Right ventricular functional recovery after acute myocardial infarction: relation with left ventricular function and interventricular septum motion. GISSI-3 echo substudy.

OBJECTIVE: To evaluate the pattern of right ventricular (RV) functional recovery and its relation with left ventricular (LV) function and interventricular septal (IVS) motion in low risk patients after acute myocardial infarction (AMI). DESIGN AND SETTING: Multicentre clinical trial carried out in 47 Italian coronary care units. PATIENTS: 500 patients from the GISSI (Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico) -3 echo substudy, who underwent serial echocardiograms 24-48 hours after symptom onset and at discharge, six weeks, and six months after AMI. RESULTS: Tricuspid annular plane systolic excursion (TAPSE) increased significantly during follow up (mean (SD) 1.79 (0.46) cm at 24-48 hours to 1.92 (0.46) cm at six months, p < 0.001) and the increase was already significant at discharge (1.88 (0.47) cm, p < 0.001). LV ejection fraction (LVEF) was the best correlate of TAPSE at 24-48 hours (r = 0.15, p = 0.001). TAPSE increased significantly in patients both with reduced (< 45%) and with preserved (> or = 45%) LVEF, but the magnitude of increase was higher in patients with lower initial LVEF (p = 0.001). Improvement in IVS wall motion score index (IVS-WMSI) was the only independent predictor of TAPSE changes during follow up (r = -0.12, p = 0.007). CONCLUSIONS: In low risk patients after AMI, RV function recovered throughout six months of follow up and was already significant at discharge. TAPSE was significantly related to LVEF at 24-48 hours. The magnitude of RV functional recovery was higher in patients with lower initial LVEF. RV functional recovery is best related to IVS-WMSI improvement, suggesting that IVS motion has an important role in RV functional improvement in this setting.

Polymorphisms of the interleukin-1beta gene affect the risk of myocardial infarction and ischemic stroke at young age and the response of mononuclear cells to stimulation in vitro.

OBJECTIVE: To investigate the role of interleukin-1beta (IL-1beta) gene polymorphisms as a link between inflammation, coagulation, and risk of ischemic vascular disease at young age. METHODS AND RESULTS: A total of 406 patients with myocardial infarction (MI) at young age, frequency-matched for age, sex, and recruitment center, with 419 healthy population-based controls and 134 patients with ischemic stroke at young age, matched by age and sex, with 134 healthy population-based controls, were studied. Subjects carrying the TT genotype of the -511C/T IL-1beta polymorphism showed a decreased risk of MI (odds ratio [OR], 0.36; 95% CI, 0.20 to 0.64) and stroke (OR, 0.32; 95% CI, 0.13 to 0.81) after adjustment for conventional risk factors. In both studies, the T allele showed a codominant effect (P=0.0020 in MI; P=0.021 in stroke). Mononuclear cells from volunteers carrying the T allele showed a decreased release of IL-1beta and a decreased expression of tissue factor after stimulation with lipopolysaccharide compared with CC homozygotes. The presence of a monoclonal antibody against IL-1beta during cell stimulation resulted in a marked reduction of tissue factor activity expression. CONCLUSIONS: -511C/T IL-1beta gene polymorphism affects the risk of MI and ischemic stroke at young age and the response of mononuclear cells to inflammatory stimulation.

Secondary prevention through cardiac rehabilitation: position paper of the Working Group on Cardiac Rehabilitation and Exercise Physiology of the European Society of Cardiology.

The purpose of this statement is to provide specific recommendations in regard to evaluation and intervention in each of the core components of cardiac rehabilitation (CR) to assist CR staff in the design and development of their programmes; the statement should also assist health care providers, insurers, policy makers and consumers in the recognition of the comprehensive nature of such programmes. Those charged with responsibility for secondary prevention of cardiovascular disease, whether at European, at national or at individual centre level, need to consider where and how structured programmes of CR can be delivered to the large constituency of patients now considered eligible for CR.

Physical activity for primary and secondary prevention. Position paper of the Working Group on Cardiac Rehabilitation and Exercise Physiology of the European Society of Cardiology.

There is now clear scientific evidence linking regular aerobic physical activity to a significant cardiovascular risk reduction, and a sedentary lifestyle is currently considered one of the five major risk factors for cardiovascular disease. In the European Union, available data seem to indicate that less than 50% of the citizens are involved in regular aerobic leisure-time and/or occupational physical activity, and that the observed increasing prevalence of obesity is associated with a sedentary lifestyle. It seems reasonable therefore to provide institutions, health services, and individuals with information able to implement effective strategies for the adoption of a physically active lifestyle and for helping people to effectively incorporate physical activity into their daily life both in the primary and the secondary prevention settings. This paper summarizes the available scientific evidence dealing with the relationship between physical activity and cardiovascular health in primary and secondary prevention, and focuses on the preventive effects of aerobic physical activity, whose health benefits have been extensively documented.

Prediction of 6 months left ventricular dilatation after myocardial infarction in relation to cardiac morbidity and mortality. Application of a new dilatation model to GISSI-3 data.

AIMS: To predict the long-term left ventricular volume index early after myocardial infarction and to investigate the relationship between long-term left ventricular dilatation risk and clinical outcome. METHODS AND RESULTS: By applying a previously developed dilatation model, we predicted the 6-month left ventricular volume index early after myocardial infarction (median 9 days) in 13,679 GISSI-3 patients, to identify patients at high risk of long-term left ventricular dilatation. The left ventricular systolic and diastolic volume indexes at 6 months were predicted with r=0.72 and r=0.68, respectively, in the subgroup of patients in whom a pre-discharge echo was available (n=7842). Patients predicted to be at risk for long-term left ventricular dilatation had an increased risk of mortality (RR 1.87, 95% CI: 1.48 to 2.36) and heart failure at 6 months (RR 2.59, 95% CI:2.04 to 3.28), but no increased risk of reinfarction at 6 months (RR 1.12, 95% CI: 0.87 to 1.45) or of angina pectoris (RR 1.07, 95% CI: 0.95 to 1.20). CONCLUSION: Our prediction of long-term left ventricular dilatation, obtained by applying our new dilatation model in over 13,000 GISSI-3 patients, correlated well with mortality and heart failure after myocardial infarction. Therefore, our new dilatation model may contribute to more efficient risk stratification early after myocardial infarction.

Relation between early mitral regurgitation and left ventricular thrombus formation after acute myocardial infarction: results of the GISSI-3 echo substudy.

OBJECTIVE: To evaluate the prevalence and correlates of left ventricular thrombosis in patients with acute myocardial infarction, and whether the occurrence of early mitral regurgitation has a protective effect against the formation of left ventricular thrombus. DESIGN AND SETTING: Multicentre clinical trial carried out in 47 Italian coronary care units. PATIENTS AND METHODS: 757 patients from the GISSI-3 echo substudy population with their first acute myocardial infarct were studied by echocardiography at 24-48 hours from symptom onset (S1), at discharge (S2), at six weeks (S3), and at six months (S4). The diagnosis of left ventricular thrombosis was based on the detection of an echo dense mass with defined margins visible throughout the cardiac cycle in at least two orthogonal views. RESULTS: In 64 patients (8%), left ventricular thrombosis was detected in one or more examinations. Compared with the remaining 693 patients, subjects with left ventricular thrombosis were older (mean (SD) age: 64.6 (13.0) v 59.8 (11.7) years, p < 0.005), and had larger infarcts (extent of wall motion asynergy: 40.9 (11.5)% v 24.9 (14)%, p < 0.001), greater depression of left ventricular ejection fraction at S1 (43.3 (6.9)% v 48.1 (6.8)%, p < 0.001), and greater left ventricular volumes at S1 (end diastolic volume: 87 (22) v 78 (18) ml/m(2), p < 0.001; end systolic volume: 50 (17) v 41 (14) ml/m(2), p < 0.001). The prevalence of moderate to severe mitral regurgitation on colour Doppler at S1 was greater in patients who had left ventricular thrombosis at any time (10.2% v 4.2%, p < 0.05). On stepwise multiple logistic regression analysis the only independent variables related to the presence of left ventricular thrombosis were the extent of wall motion asynergy and anterior site of infarction. CONCLUSIONS: Left ventricular thrombosis is not reduced, and may even be increased, by early moderate to severe mitral regurgitation after acute myocardial infarction. The only independent determinant of left ventricular thrombosis is the extent of the akinetic-dyskinetic area detected on echocardiography between 24-48 hours from symptom onset.

["Bad" sleepers... Causes, effects, and diagnosis of sleep-related breathing disorders in cardiac patients].

Cardiovascular and cerebrovascular disease are the most common life-threatening disease in the industrialized world. There is high interest in sleep apnea and cardiovascular disease: several studies have demonstrated an association between sleep apnea and cardiovascular and cerebrovascular events. The aim of this review is to critically appraise the possible adverse physiological consequences of sleep apnea on the cardiovascular system and to assess whether such adverse effects constitute a risk for the development of cardiovascular disease.

Accurate noninvasive estimation of pulmonary vascular resistance by Doppler echocardiography in patients with chronic failure heart failure.

OBJECTIVES: This study was undertaken to explore further the relationship between Doppler-derived parameters of pulmonary flow and pulmonary vascular resistance (PVR) and to determine whether PVR could be accurately estimated noninvasively from Doppler flow velocity measurements in patients with chronic heart failure. BACKGROUND: The assessment of PVR is of great importance in the management of patients with heart failure. However, because of the inconclusive and conflicting data available, Doppler estimation of PVR is still considered unreliable. METHODS: Simultaneous Doppler echocardiographic examination and right heart catheterization were performed in 63 consecutive sinus rhythm heart failure patients with severe left ventricular systolic dysfunction. Hemodynamic PVR was calculated with the standard formula. The following Doppler variables on pulmonary flow and tricuspid regurgitation velocity curve were correlated with PVR: maximal systolic flow velocity, pre-ejection period (PEP), acceleration time (AcT), ejection time, total systolic time (TT), velocity time integral, and right atrium-ventricular gradient. RESULTS: At univariate analysis, all variables except maximal systolic flow velocity and velocity time integral showed a significant, although weak, correlation with PVR. The best correlation found was between AcT and PVR (r = -0.68). By regression analysis, only PEP, AcT and TT entered into the final equation, with a cumulative r = 0.87. When the function (PEP/AcT)/TT was correlated with PVR, the correlation coefficient further improved to 0.96. Of note, this function prospectively predicted PVR (r = 0.94) after effective unloading manipulations. CONCLUSIONS: The analysis of Doppler-derived pulmonary systolic flow is a reliable and accurate tool for estimating and monitoring PVR in patients with chronic heart failure due to left ventricular systolic dysfunction.

Heterogeneity of left ventricular remodeling after acute myocardial infarction: results of the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-3 Echo Substudy.

BACKGROUND: Left ventricular (LV) remodeling after acute myocardial infarction has still to be clarified in the thrombolytic era. METHODS: To evaluate timing and the magnitude and pattern of postinfarct LV remodeling, a subset of 614 patients enrolled in the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-3 Echo Substudy underwent serial 2-dimensional echocardiograms at 24 to 48 hours from symptom onset (S1), at hospital discharge (S2), at 6 weeks (S3), and at 6 months (S4) after acute myocardial infarction. RESULTS: During the study period the end-diastolic volume index (EDVi) increased (P <.001) and wall motion abnormalities (%WMA) decreased (P <.001), whereas ejection fraction (EF) remained unchanged. Nineteen percent of patients showed a > 20% increase in EDVi at S2 compared with S1 (severe early dilation), and 16% of patients showed a > 20% dilation at S4 compared with S2 (severe late dilation). Independent predictors of severe in-hospital LV dilation were relatively small EDVi (odds ratio [OR] 0.961, 95% confidence interval [CI] 0.947-0.974, P =.0001) and relatively large %WMA (OR 1.030, 95% CI 1.013-1.048, P =.0005). Similarly, smaller predischarge EDVi (OR 0.975, 95% CI 0. 963-0.987, P =.0001), greater %WMA (OR 1.026, 95% CI 1.008-1.045, P =.0042), and moderate to severe mitral regurgitation (OR 2.261, 95% CI 1.031-4.958, P = 0.0417) independently predicted severe late dilation. Importantly, 92% of the patients with severe early dilation did not have further dilation at S4, and 91% of patients with severe late dilation did not have in-hospital dilation. EF was unchanged over time in patients with early dilation, whereas it significantly decreased in those with late dilation. CONCLUSIONS: Although in-hospital LV enlargement is not predictive of subsequent dilation and dysfunction, late remodeling is associated with progressive deterioration of global ventricular function over time: patients with extensive %WMA and not significantly enlarged ventricular volume before discharge are at higher risk for progressive dilation and dysfunction.

Chlamydia pneumoniae and cytomegalovirus seropositivity, inflammatory markers, and the risk of myocardial infarction at a young age.

BACKGROUND: Pathogens causing chronic infections may promote atherosclerosis. The aim of our study was to evaluate the association of Chlamydia pneumoniae (Cp) and cytomegalovirus (CMV) infection and of inflammatory activation with premature myocardial infarction (MI). METHODS: Specific anti-Cp and anti-CMV immunoglobulin G (IgG), fibrinogen, white blood cells (WBC), and C-reactive protein (CRP) were measured in 120 post-MI patients </=50 years old and in 120 age-matched controls. RESULTS: Seropositivity to Cp and elevated concentrations of anti-Cp and anti-CMV IgGs were more frequent (P =.01) in patients than in control subjects, and fibrinogen, CRP, and WBC levels (P =.02) were more elevated. After adjustment for coronary risk factors and socioeconomic status, the odds ratios (95% confidence intervals) for premature MI were 2.4 (1.3-4.6) for Cp infection and 2.9 (1.5-5.8) for CMV. The risk of Cp infection was greater in smokers (3.7, 1.8-7.6). When both infections were present (35% of patients vs 8% of controls, P =.001), CRP was higher (P =.01) and the risk increased by 12 times (12.5, 4-38.9) compared with that in subjects without any infection and by 5 times (4.9, 2.2-10.9) if only one was present. CONCLUSIONS: After adjustment for confounders, seropositivity to both Cp and CMV infections is associated with the diagnosis of premature MI. The combination of both infections is associated with an enhanced inflammatory response and a markedly increased risk of premature MI.

Chronic mitral regurgitation and Doppler estimation of left ventricular filling pressures in patients with heart failure.

Previous studies relating Doppler parameters and pulmonary capillary wedge pressures (PCWP) typically exclude patients with severe mitral regurgitation (MR). We evaluated the effects of varying degrees of chronic MR on the Doppler estimation of PCWP. PCWP and mitral Doppler profiles were obtained in 88 patients (mean age 55 +/- 8 years) with severe left ventricular (LV) dysfunction (mean ejection fraction 23% +/- 5%). Patients were classified by severity of MR. Patients with severe MR had greater left atrial areas, LV end-diastolic volumes, and mean PCWPs and lower ejection fractions (each P <.01). In patients with mild MR, multiple echocardiographic parameters correlated with PCWP; however, with worsening MR, only deceleration time strongly related to PCWP. From stepwise multivariate analysis, deceleration time was the best independent predictor of PCWP overall, and it was the only predictor in patients with moderate or severe MR. Doppler-derived early mitral deceleration time reliably predicts PCWP in patients with severe LV dysfunction irrespective of degree of MR.

The E27 beta2-adrenergic receptor polymorphism reduces the risk of myocardial infarction in dyslipidemic young males.

In the present study we evaluated whether two polymorphisms of beta2-adrenergic receptors (beta2-AR) gene (R16G and Q27E) could modify the risk of myocardial infarction (MI). Using a case-control design, we analyzed the data from 125 male patients who had experienced a first episode of MI before the age of 45 years and 108 male controls matched for age. The allele frequencies for R16G and Q27E were: G16=0.56 and E27=0.36 in patients with MI and G16=0.61 and E27=0.42 in the control group. There was a trend (not statistically significant) of decreasing MI risk according to E27 or G16 alleles. Combined effect between E27 allele and history of dyslipidemia has been observed. Whereas dyslipidemia conferred a relative risk of MI of 4.8 (P<0.001) compared with normolipidemia in the entire study population, the relative risk increased to 9.0 (P<0.001) in Q27 homozygotes with dyslipidemia, and decreased to 1.8 (P=0.36) in E27 homozygotes. Our results show that the E27 allele of the beta2-adrenergic receptor has a significant protective effect on MI in dyslipidemic young male.

Restrictive left ventricular filling pattern as a strong predictor of depressed baroreflex sensitivity in heart failure.

BACKGROUND: The aim of this study was to test the hypothesis that a restrictive left ventricular diastolic filling pattern, as an index of elevated pulmonary wedge pressure, would predict a depressed baroreflex sensitivity (BRS) in patients with chronic heart failure. METHODS: A total of 189 consecutive patients with an ejection fraction < or = 40% at echocardiography, in sinus rhythm and clinically stable for at least 1 month in oral therapy, underwent clinical examination, echo-Doppler study and the phenylephrine test. RESULTS: The correlations between the NYHA functional class, echo-Doppler variables and BRS were weak, although significant (r ranging from -0.15 to 0.40). However, patients with a deceleration time < 140 ms as an expression of restrictive filling, compared to those with a deceleration time > or = 140 ms, had a lower BRS (3 +/- 4 vs 6 +/- 4 ms/mmHg, p < 0.00001), a lower ejection fraction (20 +/- 6 vs 28 +/- 7%, p < 0.00001), greater left ventricular (end-diastolic volume index 137 +/- 43 vs 113 +/- 45 ml/m2, p < 0.00001) and left atrial dimensions (25 +/- 6 vs 20 +/- 5 cm2, p < 0.00001), more severe mitral regurgitation (3 +/- 1 vs 2.3 +/- 1, p < 0.00001) and were in a higher NYHA class (2.3 +/- 0.6 vs 1.8 +/- 0.5, p < 0.00001). Medications at the time of the study were similar in the two groups. At stepwise regression analysis, the deceleration time emerged as the most powerful independent predictor of a depressed BRS (< 3 ms/mmHg), followed by mitral regurgitation, age, and NYHA class (all data p = 0.0001). CONCLUSIONS: In patients with chronic heart failure, the presence of a restrictive left ventricular filling pattern is highly predictive of autonomic derangement as expressed by low values of BRS.

Independent and incremental prognostic value of (201)Tl lung uptake at rest in patients with severe postischemic left ventricular dysfunction.

BACKGROUND: An elevated (201)Tl lung uptake after stress is related to an adverse prognosis. METHODS AND RESULTS: The functional and prognostic significance of resting (201)Tl lung uptake was assessed in 124 consecutive patients with ischemic heart disease and ejection fraction </=35% undergoing rest-redistribution tomography to evaluate myocardial viability. (201)Tl lung uptake significantly correlated with pulmonary wedge pressure (r=0.66; P:<0.01) and with a restrictive physiology by Doppler echocardiography (P:<0.001). During a 13+/-13-month follow-up, 13 patients died and 23 patients required hospitalization as the result of worsening heart failure or nonfatal myocardial infarction (cumulative events rate 29%). Patients with events had a significantly higher (201)Tl lung/heart ratio (L/H) (P:<0.001). A L/H value >0.61 best separated patients with and without events (ROC area under curve 0.82). Event-free survival was significantly lower in patients with L/H >0.61 (P:<0. 001); L/H >0.61 (chi(2)=10.8; P:<0.001) and a restrictive filling pattern (chi(2)=3.6; P:<0.05) were independent predictors of events. The prognostic value of L/H was incremental over that obtained by clinical, echographic and Doppler data (global chi(2)=20.8). CONCLUSIONS: In patients with severe postischemic left ventricular dysfunction undergoing rest-redistribution (201)Tl imaging, an increased lung tracer uptake showed incremental prognostic value over clinical and other imaging findings, providing clinically useful risk assessment.

Electrocardiographic evolutionary changes and left ventricular remodeling after acute myocardial infarction: results of the GISSI-3 Echo substudy.

OBJECTIVES: The aim of this study was to describe the electrocardiographic (ECG) evolutionary changes after an acute myocardial infarction (AMI) and to evaluate their correlation with left ventricular function and remodeling. BACKGROUND: The QRS complex changes after AMI have been correlated with infarct size and left ventricular function. By contrast, the significance of T wave changes is controversial. METHODS: We studied 536 patients enrolled in the GISSI-3-Echo substudy who underwent ECG and echocardiographic studies at 24 to 48 h (S1), at hospital discharge (S2), at six weeks (S3) and six months (S4) after AMI. RESULTS: The number of Qwaves (nQ) and QRS quantitative score (QRSs) did not change over time. From S2 to S4, the number of negative T waves (nT NEG) decreased (p < 0.0001), wall motion abnormalities (%WMA) improved (p < 0.001), ventricular volumes increased (p < 0.0001) while ejection fraction remained stable. According to the T wave changes after hospital discharge, patients were divided into four groups: stable positive T waves (group 1, n = 35), patients who showed a decrease > or =1 in nT NEG (group 2, n = 361), patients with no change in nT NEG (group 3, n = 64) and those with an increase > or =1 in nT NEG (group 4, n = 76). The QRSs and nQ remained stable in all groups. Groups 3 and 4 showed less recovery in %WMA, more pronounced ventricular enlargement and progressive decline in ejection fraction than groups 1 and 2 (interaction time x groups p < 0.0001). CONCLUSIONS: The analysis of serial ECG can predict postinfarct left ventricular remodeling. Normalization of negative T waves during the follow-up appears more strictly related to recovery of regional dysfunction than QRS changes. Lack of resolution and late appearance of new negative T predict unfavorable remodeling with progressive deterioration of ventricular function.

Habitual activities and peak aerobic capacity in patients with asymptomatic and symptomatic left ventricular dysfunction.

BACKGROUND: A reduced level of daily activities is thought to be an important determinant of aerobic exercise intolerance in patients with chronic heart failure chronic heart failure; however, few data exist about the relationship between habitual physical activity level and peak aerobic capacity in patients at different clinical stages of left ventricular dysfunction. STUDY OBJECTIVES: The purposes of this study were as follow: (1) to validate a simple interviewer-administered scoring system for evaluation of habitual physical activity level of patients with chronic heart failure and asymptomatic left ventricular dysfunction (ALVD); (2) to determine the relationship between habitual physical activity level and peak aerobic capacity in chronic heart failure and ALVD patients; and (3) to compare habitual activity levels among different New York Heart Association (NYHA) classes in these populations. SETTING: Cardiology division at a tertiary-care hospital. STUDY POPULATION: We studied 167 consecutive patients with chronic heart failure (NYHA class I to III), 40 patients with ALVD, and 52 healthy subjects (HS). MEASUREMENTS AND RESULTS: Habitual physical activity level was evaluated by means of an interview-based activity scoring system considering leisure time and occupational activities and also recent deconditioning events (eg, hospital admissions); a final activity score (AS) ranging from 0.8 to 5 was obtained. All patients and HS performed a symptom-limited cardiopulmonary exercise test up to a respiratory exchange ratio of > or = 1.1. AS was an independent predictor of peak oxygen consumption (VO(2)) in all groups, with a significantly higher VO(2) vs AS relationship slope in the ALVD and HS groups than in the chronic heart failure group. Moreover, AS was found to be significantly lower in chronic heart failure than in ALVD patients and HS (1.6 +/- 0.6 vs 2.2 +/- 0.7 vs 3.5 +/- 1.1, respectively; p < 0.0001), as was peak VO(2) (14.7 +/- 3.7 mL/kg/min vs 20 +/- 4 mL/kg/min vs 33.1 +/- 10 mL/kg/min, respectively; p < 0.0001), but the latter differences were canceled after adjusting for AS values. Significant AS and peak VO(2) reductions were observed in chronic heart failure patients with NYHA class progression from I to III. CONCLUSIONS: Habitual physical activity level is progressively decreased with worsening of heart failure symptoms and is related to peak aerobic capacity in both chronic heart failure and ALVD patients. However, this relationship appears to be weak in patients with chronic heart failure, whereas daily activity is a strong independent predictor of peak aerobic capacity both in ALVD patients and HS. This may be related to the intervention of factors other than skeletal muscle deconditioning in the exercise pathophysiology of chronic heart failure patients.
