Assessment of patients at intermediate cardiac risk.

The optimal approach to patients who are at intermediate risk for coronary artery disease is not clear. Various risk assessment scoring systems and imaging modalities can add diagnostic and prognostic value to cardiovascular evaluation. A better understanding of these available assessment tools can help physicians to optimize management and outcomes in patients who are initially categorized as at intermediate risk. Detailed case studies are presented that illustrate the use of these assessment tools in patients at intermediate risk.

Opportunity for intervention to achieve American Heart Association guidelines for optimal lipid levels in high-risk women in a managed care setting.

BACKGROUND: The American Heart Association (AHA) recently established evidence-based recommendations for cardiovascular disease (CVD) prevention in women, including lipid management. This study evaluated optimal lipid-level attainment and treatment patterns on the basis of these guidelines in high-risk women in a managed care setting. METHODS AND RESULTS: We conducted a historical prospective cohort analysis of a 1.1-million-member, integrated, managed-care database. Eligible high-risk women were those with evidence of previous CVD or risk equivalent who had a full lipid panel available between October 1, 1999, and September 30, 2000; were naive to lipid therapy; and had a minimum of 12 months health plan eligibility preindex and postindex lipid panel. Optimal lipid levels were defined as LDL cholesterol (LDL-C) <100 mg/dL, HDL cholesterol (HDL-C) >50 mg/dL, non-HDL-C <130 mg/dL, and triglycerides <150 mg/dL. Laboratory values and lipid pharmacotherapy were assessed longitudinally over the postindex follow-up (up to 36 months). A total of 8353 high-risk women (mean age, 66+/-14 years) with a mean follow-up of 27+/-8 months were included. Only 7% attained optimal combined lipid levels initially, and this increased to 12% after 36 months. Lipid-modifying therapy was initiated in 32% of patients, including 35% of women with LDL-C > or =100 mg/dL and 15% with LDL-C <100 mg/dL. CONCLUSIONS: Among high-risk women, few attained the AHA's standards for all lipid fractions, and only one third received recommended drug therapy, highlighting significant opportunities to apply evidence-based recommendations to manage lipid abnormalities in high-risk women.

Relationship of physical fitness vs body mass index with coronary artery disease and cardiovascular events in women.

CONTEXT: Individual contributions of obesity and physical fitness (physical activity and functional capacity) to risk of coronary heart disease in women remain unclear. OBJECTIVE: To investigate the relationships of measures of obesity (body mass index [BMI], waist circumference, waist-hip ratio, and waist-height ratio) and physical fitness (self-reported Duke Activity Status Index [DASI] and Postmenopausal Estrogen-Progestin Intervention questionnaire [PEPI-Q] scores) with coronary artery disease (CAD) risk factors, angiographic CAD, and adverse cardiovascular (CV) events in women evaluated for suspected myocardial ischemia. DESIGN, SETTING, AND PARTICIPANTS: The National Heart, Lung, and Blood Institute-sponsored Women's Ischemia Syndrome Evaluation (WISE) is a multicenter prospective cohort study. From 1996-2000, 936 women were enrolled at 4 US academic medical centers at the time of clinically indicated coronary angiography and then assessed (mean follow-up, 3.9 [SD, 1.8] years) for adverse outcomes. MAIN OUTCOME MEASURES: Prevalence of obstructive CAD (any angiographic stenosis >or=50%) and incidence of adverse CV events (all-cause death or hospitalization for nonfatal myocardial infarction, stroke, congestive heart failure, unstable angina, or other vascular events) during follow-up. RESULTS: Of 906 women (mean age, 58 [SD, 12] years) with complete data, 19% were of nonwhite race, 76% were overweight (BMI >or=25), 70% had low functional capacity (DASI scores <25, equivalent to <or=7 metabolic equivalents [METs]), and 39% had obstructive CAD. During follow-up, 337 (38%) women had a first adverse event, 118 (13%) had a major adverse event, and 68 (8%) died. Overweight women were more likely than normal weight women to have CAD risk factors, but neither BMI nor abdominal obesity measures were significantly associated with obstructive CAD or adverse CV events after adjusting for other risk factors (P =.05 to.88). Conversely, women with lower DASI scores were significantly more likely to have CAD risk factors and obstructive CAD (44% vs 26%, P<.001) at baseline, and each 1-MET increase in DASI score was independently associated with an 8% (hazard ratio, 0.92; 95% confidence interval, 0.85-0.99; P =.02) decrease in risk of major adverse CV events during follow-up. CONCLUSIONS: Among women undergoing coronary angiography for suspected ischemia, higher self-reported physical fitness scores were independently associated with fewer CAD risk factors, less angiographic CAD, and lower risk for adverse CV events. Measures of obesity were not independently associated with these outcomes.
