Socioeconomic status as an independent risk factor for hospital readmission for heart failure.

The management of heart failure is characterized by high rates of hospital admission as well as rehospitalization after inpatient treatment of this disorder, whereas skillful medical care may reduce the risk of hospital admission. The purpose of this study was to examine the relation between income (as a measure of socioeconomic status) and the frequency of hospital readmission among a large and diverse group of persons treated for heart failure. We analyzed administrative discharge data from 236 nonfederal acute-care hospitals in New York State, involving 41,776 African-American or Caucasian hospital survivors with International Classification of Diseases, Ninth Revision, Clinical Modification codes for heart failure in the principal diagnosis position between January 1 and December 31, 1995. Household income was derived from postal ZIP codes and census data. We found that patients residing in lower income neighborhoods were more often women or African-Americans, had more comorbid illness, had higher use of Medicaid insurance, and were more often admitted to rural hospitals. There was a stepwise decrease in the crude frequency of readmission from the lowest quartile of income (23.2%) to the highest (20.0%) (p <0.0001 for Mantel-Haenszel chi-square test for trend across all quartiles; p <0.0001 for comparison between quartiles 1 and 4). After adjustment for baseline differences and process of care, income remained a significant predictor, with an increase in the risk of readmission noted in association with lower levels of income (adjusted odds ratio for quartile 1:4 comparison, 1.18; 95% confidence interval, 1.10 to 1.26, p <0.0001). We conclude that lower income patients hospitalized for treatment of heart failure in New York differ from higher income patients in important clinical and demographic comparisons. Even after adjustment for these fundamental differences and other potential confounding factors, lower income is a positive predictor of readmission risk.

Length of stay and procedure utilization are the major determinants of hospital charges for heart failure.

BACKGROUND: Most of the 10 billion dollars spent annually on heart failure (HF) management in this country is attributed to hospital charges. There are widespread efforts to decrease the costs of treating this disorder, both by preventing hospital admissions and reducing lengths of stay (LOS). HYPOTHESIS: The objective of this study was to identify the major determinants of hospital charges for an acute hospitalization for HF among a large, diverse group of patients. METHODS: Administrative information on all 1995 New York State hospital discharges assigned ICD-9-CM codes indicative of HF in the principal diagnosis position were obtained. Bivariate and multivariate statistical analyses were utilized to determine those patient- and hospital-specific characteristics which had the greatest influence on hospital charges. RESULTS: In all, 43,157 patients were identified. Mean hospital charges were $11,507+/-15,995 and mean hospital LOS was 9.6+/-14.5 days. With multivariate analyses, the most significant independent predictors of higher hospital charges were longer LOS, admission to a teaching hospital, treatment in an intensive care unit, and the utilization of cardiac surgery, permanent pacemakers, and mechanical ventilation. Age, gender, race, comorbidity score, and medical insurance, as well as treatment by a cardiologist and death during the index hospitalization were not among the most significant predictors. CONCLUSIONS: We conclude that LOS and procedure utilization are the major determinants of hospital charges for an acute episode of inpatient HF care. Reducing LOS and other initiatives to restructure hospital-based HF care may reduce total health care costs for HF.

Underuse of invasive procedures among Medicaid patients with acute myocardial infarction.

OBJECTIVES: The purpose of this study was to determine whether underuse of cardiac procedures among Medicaid patients with acute myocardial infarction is explained by or is independent of fundamental differences in age, race, or sex distribution; income, coexistent illness; or location of care. METHODS: Administrative data from 226 hospitals in New York were examined for 11,579 individuals hospitalized with a primary diagnosis of acute myocardial infarction. Use of various cardiac procedures was compared among Medicaid patients and patients with other forms of insurance. RESULTS: Medicaid patients were older, were more frequently African American and female, and had lower median household incomes. They also had a higher prevalence of hypertension, diabetes, lung disease, renal disease, and peripheral vascular disease. After adjustment for these and other factors, Medicaid patients were less likely to undergo cardiac catheterization, percutaneous transluminal coronary angioplasty, and any revascularization procedure. CONCLUSIONS: Factors other than age, race, sex, income, coexistent illness, and location of care account for lower use of invasive procedures among Medicaid patients. The influence of Medicaid insurance on medical practice and process of care deserves investigation.

Systolic versus diastolic heart failure in community practice: clinical features, outcomes, and the use of angiotensin-converting enzyme inhibitors.

BACKGROUND: Among patients with heart failure, there is controversy about whether there are clinical features and laboratory tests that can differentiate patients who have low ejection fractions from those with normal ejection fractions. The usefulness of angiotensin-converting enzyme (ACE) inhibitors among heart failure patients who have normal left ventricular ejection fractions is also not known. METHODS: From a registry of 2,906 unselected consecutive patients with heart failure who were admitted to 10 acute-care community hospitals during 1995 and 1997, we identified 1291 who had a quantitative measurement of their left ventricular ejection fraction. Patients were separated into three groups based on ejection fraction: < or =0.39 (n = 741, 57%), 0.40 to 0.49 (n = 238, 18%), and > or =0.50 (n = 312, 24%). In-hospital mortality, prescription of ACE inhibitors at discharge, subsequent rehospitalization, quality of life, and survival were measured; survivors were observed for at least 6 months after hospitalization. RESULTS: The mean (+/- SD) age of the sample was 75+/-11 years; the majority (55%) of patients were women. In multivariate models, age >75 years, female sex, weight >72.7 kg, and a valvular etiology for heart failure were associated with an increased probability of having an ejection fraction > or =0.50; a prior history of heart failure, an ischemic or idiopathic cause of heart failure, and radiographic cardiomegaly were associated with a lower probability of having an ejection fraction > or =0.50. Total mortality was lower in patients with an ejection fraction > or =0.50 than in those with an ejection fraction < or =0.39 (odds ratio [OR] = 0.69, 95% confidence interval [CI 0.49 to 0.98, P = 0.04). Among hospital survivors with an ejection fraction of 0.40 to 0.49, the 65% who were prescribed ACE inhibitors at discharge had better mean adjusted quality-of-life scores (7.0 versus 6.2, P = 0.02), and lower adjusted mortality (OR = 0.34, 95% CI: 0.17 to 0.70, P = 0.01) during follow-up than those who were not prescribed ACE inhibitors. Among hospital survivors with an ejection fraction > or =0.50, the 45% who were prescribed ACE inhibitors at discharge had better (lower) adjusted New York Heart Association (NYHA) functional class (2.1 versus 2.4, P = 0.04) although there was no significant improvement in survival. CONCLUSIONS: Among patients treated for heart failure in community hospitals, 42% of those whose ejection fraction was measured had a relatively normal systolic function (ejection fraction > or 0.40). The clinical characteristics and mortality of these patients differed from those in patients with low ejection fractions. Among the patients with ejection fractions > or =0.40, the prescription of ACE inhibitors at discharge was associated favorable effects.

Socioeconomic status is an important determinant of the use of invasive procedures after acute myocardial infarction in New York State.

BACKGROUND: Patient and hospital characteristics influence the use of invasive cardiac procedures. Whether socioeconomic status (SES) has an influence that is independent of these other determinants is unclear. The purpose of the present study was to examine the influence of household income as a measure of SES on the use of invasive cardiac procedures among a large group of patients with acute myocardial infarction. METHODS AND RESULTS: We analyzed administrative discharge data from 231 nonfederal acute care hospitals in New York State that involved 28 698 black or white inpatients with International Classification of Diseases, Ninth Revision, Clinical Modification code 410.XX in the principal diagnosis position between January 1 and December 31, 1995. Household income was derived from postal ZIP codes and census data. The use of cardiac catheterization, PTCA, CABG, and any revascularization procedure was examined across groups stratified by income. Patients who resided in lower-income neighborhoods were more often female or black, had a higher prevalence of coexistent illness, had a higher use of Medicaid insurance, and were less often admitted to urban hospitals or hospitals that provide on-site CABG and PTCA. Crude and adjusted odds ratios for catheterization, PTCA, CABG, and any revascularization procedure were related to income in a graded fashion. After adjustment, patients in the highest quintile of income were 22% more likely to undergo catheterization, 74% more likely to undergo PTCA, 48% more likely to undergo CABG, and 76% more likely to undergo any revascularization procedure than were patients in the lowest quintile. The difference in cardiac catheterization did not fully account for income-based differences in revascularization, because income remained a significant determinant of revascularization after accounting for whether a catheterization was performed. Even among patients treated in hospitals that provide on-site CABG and PTCA, income was a significant determinant of procedures. CONCLUSIONS: Lower-income patients hospitalized for acute myocardial infarction are more often female or black, have more coexisting illnesses, and are less often admitted to urban hospitals or hospitals that provide CABG and PTCA. Even after adjustment for these and other factors, lower income is a negative predictor of procedure use.

The results of a randomized trial of a quality improvement intervention in the care of patients with heart failure. The MISCHF Study Investigators.

PURPOSE: Quality improvement and disease management programs for heart failure have improved quality of care and patient outcomes at large tertiary care hospitals. The purpose of this study was to measure the effects of a regional, multihospital, collaborative quality improvement intervention on care and outcomes in heart failure in community hospitals. PATIENTS AND METHODS: This randomized controlled study included 10 acute care community hospitals in upstate New York. After a baseline period, 5 hospitals were randomly assigned to receive a multifaceted quality improvement intervention (n = 762 patients during the baseline period; n = 840 patients postintervention), while 5 were assigned to a "usual care" control (n = 640 patients during the baseline period; n = 664 patients postintervention). Quality of care was determined using explicit criteria by reviewing the charts of consecutive patients hospitalized with the primary diagnosis of heart failure during the baseline period and again in the postintervention period. Clinical outcomes included hospital length of stay and charges, in-hospital and 6-month mortality, hospital readmission, and quality of life measured after discharge. RESULTS: Patients had similar characteristics in the baseline and postintervention phases in the intervention and control groups. Using hospital-level analyses, the intervention had mixed effects on 5 quality-of-care markers that were not statistically significant. The mean of the average length of stay among hospitals decreased from 8.0 to 6.2 days in the intervention group, with a smaller decline in mean length of stay in the control group (7.7 to 7.0 days). The net effects of the intervention were nonsignificant changes in length of stay of -1.1 days (95% confidence interval [CI]: -2.9 to 0.7 days, P = 0.18) and in hospital charges of -$817 (95% CI: -$2560 to $926, P = 0.31). There were small and nonsignificant effects on mortality, hospital readmission, and quality of life. CONCLUSIONS: The incremental effect of regional collaboration among peer community hospitals toward the goal of quality improvement was small and limited to a slightly, but not significantly, shorter length of stay.

Dilated cardiomyopathy and sensorineural hearing loss: a heritable syndrome that maps to 6q23-24.

BACKGROUND: Dilated cardiomyopathy (DCM) and sensorineural hearing loss (SNHL) are prevalent disorders that occur alone or as components of complex multisystem syndromes. Multiple genetic loci have been identified that, when mutated, cause DCM or SNHL. However, the isolated coinheritance of these phenotypes has not been previously recognized. METHODS AND RESULTS: Clinical evaluations of 2 kindreds demonstrated autosomal-dominant transmission and age-related penetrance of both SNHL and DCM in the absence of other disorders. Moderate-to-severe hearing loss was evident by late adolescence, whereas ventricular dysfunction produced progressive congestive heart failure after the fourth decade. DNA samples from the larger kindred (29 individuals) were used to perform a genome-wide linkage study. Polymorphic loci on chromosome 6q23 to 24 were coinherited with the disease (maximum logarithm of odds score, 4.88 at locus D6S2411). The disease locus must lie within a 2.8 cM interval between loci D6S975 and D6S292, a location that overlaps an SNHL disease locus (DFNA10). However, DFNA10 does not cause cardiomyopathy. The epicardin gene, which encodes a transcription factor expressed in the myocardium and cochlea, was assessed as a candidate gene by nucleotide sequence analysis; no mutations were identified. CONCLUSIONS: A syndrome of juvenile-onset SNHL and adult-onset DCM is caused by a mutation at 6q23 to 24 (locus designated CMD1J). Recognition of this cardioauditory disorder allows for the identification of young adults at risk for serious heart disease, thereby enabling early intervention. Definition of the molecular cause of this syndrome may provide new information about important cell physiology common to both the ear and heart.

Differences between patients with heart failure treated by cardiologists, internists, family physicians, and other physicians: analysis of a large, statewide database.

BACKGROUND: The management of heart failure (HF) by cardiologists may be better than that of other physicians in that cardiologists' treatment choices more frequently conform with published guidelines and the results of clinical trials. Whether cardiologists' management of HF is more or less cost-effective is up for debate. METHODS: Information on all 1995 New York state hospital discharges assigned ICD-9-CM codes indicative of HF in the principal diagnosis position was obtained. Demographic and clinical characteristics, process of care, resource utilization, and short-term HF-related outcomes were compared between patients of cardiologists and patients of other physicians. RESULTS: A total of 44,926 patients were identified, with 10,506 (23%) receiving care from cardiologists, 28,300 (63%) from internists, 4812 (11%) from family practitioners, and 1308 (3%) from other physicians. Patients of cardiologists were younger, more frequently male, and less frequently residents of nursing homes. They were more likely to have associated cardiovascular diagnoses but less likely to have comorbid general medical conditions. Patients of cardiologists were more likely to undergo cardiac catheterization (9%) than those of internists (3%) and family practice (2%) physicians but had similar adjusted hospital length of stay and charges. Mortality and hospital readmission rates for HF were similar among the groups. Patients in the "other" group (managed mostly by surgeons) were the youngest, underwent more invasive and cardiac surgical procedures, and had the longest length of stay and highest hospital charges. CONCLUSIONS: Cardiologists' management of HF is not economically disadvantageous. The relations among physician specialty, process of care, resource utilization, and clinical outcomes require further study before rational and evidence-based health care staffing recommendations can be formulated.

Race-related differences among patients with left ventricular dysfunction: observations from a biracial angiographic cohort. Harlem-Bassett LP(A) Investigators.

BACKGROUND: This study was designed to describe race-related differences in left ventricular function among a consecutive series of patients undergoing cardiac catheterization and to identify racial differences in coexistent medical and social conditions that are associated with the development of heart failure (HF). METHODS AND RESULTS: This was a prospective cohort study conducted at 2 university-affiliated teaching hospitals. We used the database of the Harlem-Bassett Lp(a) Study. We included all black (N = 143) or white (N = 313) patients from the main study database for whom complete survey, laboratory, coronary angiographic, and ventriculographic data were available. "Left ventricular dysfunction" was arbitrarily defined as an ejection fraction < or =0.40 or prior pharmacologic treatment for HF. We found that blacks were younger, had a higher proportion of women, and had fewer years of formal education than their white counterparts. Coronary artery disease was less common among blacks, although this group had a higher prevalence of hypertension, diabetes, cigarette smoking, illicit drug use, and alcohol consumption. Black patients had a higher prevalence of previous treatment for HF, larger left ventricular volumes, and lower ejection fractions than white patients. Blacks with left ventricular dysfunction were more likely to have had a previous myocardial infarction or a history of hypertension compared with those without left ventricular dysfunction. CONCLUSIONS: Regarding left ventricular dysfunction and HF, we conclude that blacks seem to have a much higher burden of disease than whites. Our observations support prior evidence that hypertension is linked to race-related differences in the epidemiology of HF. The interaction between race and access to quality care for HF remains an important area for future investigation.

High levels of Lp(a) with a small apo(a) isoform are associated with coronary artery disease in African American and white men.

Elevated levels of lipoprotein(a) [Lp(a)] and the presence of small isoforms of apolipoprotein(a) [apo(a)] have been associated with coronary artery disease (CAD) in whites but not in African Americans. Because of marked race/ethnicity differences in the distribution of Lp(a) levels across apo(a) sizes, we tested the hypothesis that apo(a) isoform size determines the association between Lp(a) and CAD. We related Lp(a) levels, apo(a) isoforms, and the levels of Lp(a) associated with different apo(a) isoforms to the presence of CAD (>/=50% stenosis) in 576 white and African American men and women. Only in white men were Lp(a) levels significantly higher among patients with CAD than in those without CAD (28.4 versus 16.5 mg/dL, respectively; P:=0.004), and only in this group was the presence of small apo(a) isoforms (<22 kringle 4 repeats) associated with CAD (P:=0.043). Elevated Lp(a) levels (>/=30 mg/dL) were found in 26% of whites and 68% of African Americans, and of those, 80% of whites but only 26% of African Americans had a small apo(a) isoform. Elevated Lp(a) levels with small apo(a) isoforms were significantly associated with CAD (P:<0.01) in African American and white men but not in women. This association remained significant after adjusting for age, diabetes mellitus, smoking, hypertension, HDL cholesterol, LDL cholesterol, and triglycerides. We conclude that elevated levels of Lp(a) with small apo(a) isoforms independently predict risk for CAD in African American and white men. Our study, by determining the predictive power of Lp(a) levels combined with apo(a) isoform size, provides an explanation for the apparent lack of association of either measure alone with CAD in African Americans. Furthermore, our results suggest that small apo(a) size confers atherogenicity to Lp(a).

Left ventricular thrombus and subsequent thromboembolism in patients with severe systolic dysfunction.

STUDY OBJECTIVES: To determine the frequency of left ventricular (LV) thrombi by echocardiography and to define the predictors of LV thrombus and subsequent thromboembolism. DESIGN: Retrospective case-control design. SETTING: Single tertiary care center. PATIENTS: Twenty-eight patients with LV thrombus in a consecutive series of 144 patients with severe LV dysfunction and follow-up period for a mean of 27.6 months. MEASUREMENTS AND RESULTS: Thirty-five clinical and echocardiographic variables were evaluated. The mean age of patients with (n = 28) vs patients without (n = 116) LV thrombus was 50.3 +/- 11.0 years vs 54.2 +/- 11.1 years (p = 0.09), with 22 patients (78.6%) and 78 patients (67.2%) being male (p = 0.24), respectively. The mean ejection fraction (EF) for those with vs those without LV thrombus was 17.5 +/- 5.5 vs 20.0 +/- 6.9 (p = 0. 08), with 16 patients (57.1%) and 42 patients (36.2%) having an EF < 20% (p = 0.04), respectively. The groups were similar with respect to other baseline characteristics, comorbid illnesses, and drug therapies other than anticoagulants. All 28 patients with LV thrombus (100%) and 54 of those without LV thrombus (46.6%) were treated with warfarin. Ischemic etiology of the cardiomyopathy (odds ratio, 4.78; 95% confidence interval, 1.51 to 15.11; p = 0.008) and increased LV internal diastolic dimension (LVIDD; odds ratio, 1.10; 95% confidence interval, 1.03 to 1.18; p = 0.004) were found to be independent predictors of thrombus formation. Peripheral embolism occurred in 5 patients (17.9%) vs 13 patients (11.2%) of those with and without LV thrombi, respectively (p = 0.35). Ischemic etiology of the cardiomyopathy (odds ratio, 3.79; 95% confidence interval, 1. 13 to 12.64; p = 0.03) and EF (odds ratio, 0.91; 95% confidence interval, 0.82 to 1.00; p = 0.04) were found to be independent predictors of systemic embolization. The patients with an embolic event suffered a significantly higher mortality (7 of 18 patients; 38.9%) during the follow-up period when compared to those without an embolic event (13 of 126 patients; 10.3%; p < 0.0001). CONCLUSIONS: We conclude that ischemic cardiomyopathy and dilated LV chamber sizes (LVIDD > 60 mm) are independently associated with LV thrombi. A peripheral embolic event is related to poor long-term survival in this patient group.

Cholesterol lowering with pravastatin improves resistance artery endothelial function: report of six subjects with normal coronary arteriograms.

STUDY OBJECTIVES: Improvement in coronary artery endothelial function has been demonstrated after cholesterol lowering in hypercholesterolemic patients with significant atherosclerosis. However, to our knowledge, no previous study has shown improvement in resistance artery function in subjects with normal coronary arteries after cholesterol lowering. The purpose of our study was to investigate the effect of cholesterol lowering with pravastatin on coronary resistance artery endothelial function in the setting of angiographically normal coronary arteries. METHODS: Invasive testing of coronary endothelial and vasomotor function was performed at baseline and after 6 months of pravastatin treatment in six patients with normal coronary arteriograms. RESULTS: After 6 months of pravastatin treatment, low-density lipoprotein cholesterol level dropped from 157+/-11 to 117+/-8 mg/dL (p = 0.02) and percent increase in coronary blood flow after acetylcholine improved from 97+/-13% to 160+/-16% (p = 0.01). There was a trend (p = 0.17) toward enhanced epicardial dilation in response to acetylcholine after pravastatin treatment when compared with the baseline study. CONCLUSIONS: Our study demonstrates significant improvement in coronary resistance artery endothelial function after 6 months of cholesterol lowering with pravastatin in six subjects presenting with chest pain who were found to have normal coronary arteriograms. A trend toward improved epicardial vasomotion was also observed.

Clinical outcomes in heart failure: report from a community hospital-based registry.

PURPOSE: Most of the recent information on the prognosis of patients with heart failure has come from large clinical trials or tertiary care centers. This study reports current information from a community hospital-based heart failure registry. SUBJECTS AND METHODS: We compiled data from 2,906 unselected consecutive patients with heart failure who were admitted to 10 acute care community hospitals in New York State between 1995 and 1997. Patients were followed prospectively for 6 months after hospital discharge or until their death. RESULTS: The mean (+/- SI)) age of the sample was 76 +/- 11 years. The majority of the patients were women (56%) and most were white (95%). Hospital length of stay averaged 7.4 +/- 7.6 days; hospital charges averaged $7,460 +/- $6,114. Mortality during the index admission was 5%. Among the 2,508 patients for whom mortality or follow-up data were available, an additional 411 died during follow-up, for a cumulative 6-month mortality of 23%. Progressive pump failure was the predominant cause of death in the hospital and after discharge. Although mean functional class (on a 1 to 4 scale) improved from 3.4 +/- 0.7 at hospital admission to 2.3 +/- 0.9 at 1 month after discharge, 43% of patients had at least one hospital readmission during follow-up and 25% had at least one recurrent admission for heart failure. The mean time from index discharge to first rehospitalization was 60 +/- 56 days. In all, 55% of patients (1,370 of 2,508) were rehospitalized or died during the study period. CONCLUSIONS: Despite advances in the management of heart failure, patients recently hospitalized for this disorder remain at high risk of death, hospital readmission, and poor clinical outcome. Discovery or implementation of new or existing methods of prevention and treatment remain a high priority.

Prediction of hospital readmission for heart failure: development of a simple risk score based on administrative data.

OBJECTIVES: The purpose of this study was to develop a convenient and inexpensive method for identifying an individual's risk for hospital readmission for congestive heart failure (CHF) using information derived exclusively from administrative data sources and available at the time of an index hospital discharge. BACKGROUND: Rates of readmission are high after hospitalization for CHF. The significant determinants of rehospitalization are debated. METHODS: Administrative information on all 1995 hospital discharges in New York State which were assigned International Classification of Diseases-9-Clinical Modification codes indicative of CHF in the principal diagnosis position were obtained. The following were compared among hospital survivors who did and did not experience readmission: demographics, comorbid illness, hospital type and location, processes of care, length of stay and hospital charges. RESULTS: A total of 42,731 black or white patients were identified. The subgroup of 9,112 patients (21.3%) who were readmitted were distinguished by a greater proportion of blacks, a higher prevalence of Medicare and Medicaid insurance, more comorbid illnesses and the use of telemetry monitoring during their index hospitalization. Patients treated at rural hospitals, those discharged to skilled nursing facilities and those having echocardiograms or cardiac catheterization were less likely to be readmitted. Using multiple regression methods, a simple methodology was devised that segregated patients into low, intermediate and high risk for readmission. CONCLUSIONS: Patient characteristics, hospital features, processes of care and clinical outcomes may be used to estimate the risk of hospital readmission for CHF. However, some of the variation in rehospitalization risk remains unexplained and may be the result of discretionary behavior by physicians and patients.

Comprehensive multidisciplinary programs for the management of patients with congestive heart failure.

OBJECTIVE: To evaluate the impact of comprehensive, multidisciplinary management programs on the process of care, resource utilization, health care costs, and clinical outcomes in patients with congestive heart failure. MEASUREMENTS AND MAIN RESULTS: A MEDLINE search identified seven english-language reports that compared the process of care, clinical outcomes, or economic variables related to implementation of a multidisciplinary congestive heart failure management program of at least 3 month's duration to a control or reference group. The primary intent of the programs was to emphasize compliance with recommended therapeutic principles, enhance patient education, and provide careful patient surveillance. Five of the studies reported improved functional status, aerobic capacity, or patient satisfaction. Six of the studies reported a 50% to 85% reduction in the risk of hospital admission. Three studies reported economic analyses with suggestive but not compelling evidence of financial benefit. CONCLUSIONS: Comprehensive, multidisciplinary management programs for congestive heart failure can improve functional status and reduce the risk of hospital admission, and they may lower medical costs.

Angiotensin-converting enzyme inhibitor use in older patients with heart failure and renal dysfunction.

OBJECTIVE: To examine the relationship between angiotensin-converting enzyme (ACE) inhibitor use and clinical outcomes among recently hospitalized patients with congestive heart failure (CHF) and coexisting renal insufficiency. DESIGN: A prospective cohort study. SETTING: Ten community hospitals in upstate New York. PARTICIPANTS: A total of 1076 hospital survivors identified from a consecutive series of CHF inpatients. MEASUREMENTS: Patients were followed prospectively for 6 months after hospital discharge to track mortality, hospital readmission, and quality of life. Clinical outcomes were stratified by ACE inhibitor use among those with renal dysfunction, defined as serum creatinine > or = 2.0 mg/dL, and among the remaining patients, whose serum creatinine was < or = 1.9. RESULTS: ACE inhibitor use was lower among 187 patients with renal dysfunction than among 889 patients with preserved function (41 vs 69%, P < .001). Age and sex were among the significant determinants of drug use in both groups. After adjustment for covariables, ACE inhibitor use among those with abnormal renal function was not associated with a lower risk for death or readmission, or better quality of life. By comparison, ACE inhibition conferred meaningful clinical benefit among those whose creatinine was < or = 1.9 mg/dL. CONCLUSION: Convincing evidence of clinical benefit from ACE inhibitor use is not readily detectable among a sample of 187 unselected older patients with CHF and moderate or severe renal insufficiency. Further studies to identify subsets of this group who might benefit are warranted.

Heart transplant for dilated cardiomyopathy associated with polymyositis.

Cardiac involvement is one of the most significant factors in the poor clinical outcome of polymyositis. The case of a 39 year old African American woman with polymyositis, cardiomyopathy, and severe heart failure who had orthotopic heart transplantation is described. Review of the literature reveals that cardiac manifestations of polymyositis are frequent and include conduction system abnormalities, myocarditis, cardiomyopathy, coronary artery atherosclerosis, valvar disease, and pericardial abnormalities.

Cardiology or primary care for heart failure in the community setting: process of care and clinical outcomes.

STUDY OBJECTIVES: Severity of illness, treatment choices, and clinical outcomes may vary with physician training. This study was performed to determine whether such differences exist among patients with congestive heart failure (CHF) treated by cardiologists and by noncardiologists in the community hospital setting. DESIGN: Prospective cohort study. SETTING: Ten acute-care community hospitals. PATIENTS, MEASUREMENTS, AND RESULTS: Two thousand four hundred fifty-four patients with CHF were identified and followed up for 6 months after hospital discharge. Patients who were not treated by a cardiologist (group I; n = 977) were compared with patients whose attending physician was a cardiologist (group II; n = 419) and patients who received consultative care from a cardiologist (group III; n = 1,058). When compared with group I patients, group II patients were more likely to receive the recommended diagnostic tests and treatment strategies, although some of these differences could be explained by variations in the case mix. Group II patients had higher hospital charges, but lower CHF readmission rates and better postdischarge quality-of-life measures. No differences in adjusted mortality rates were observed. CONCLUSIONS: In the community-hospital setting, the clinical practices of cardiologists are more compatible with published treatment guidelines than the clinical practices of other physicians. The benefits of cardiology specialty care include lower CHF readmission rates and better postdischarge quality-of-life measures, rather than lower mortality rates, fewer hospital charges, or shorter length of stay.
