Enhanced External Counterpulsation Therapy Medical Management versus Coronary Revascularization Angiographic studies on patients before myocardial infarction show that the majority of subsequent events involve sites with < 70% obstruction. Falk E. et al. Circ 1995;92:657 The new picture of atherosclerosis explains why many heart attacks come from out of the blue: the plaques that rupture do not necessarily protrude very far into the blood channel and so may not cause angina or ischemic ST-segment depression.

AJC 2006;78:1550 The Polypill as Part of a Global Strategy to Substantially Reduce the CVD Burden The polypill could potentially be widely used in secondary prevention and in selected high-risk individuals without known CVD (e.g., those with diabetes mellitus with additional risk factors). In such individuals, a 50% to 75% proportional reduction in risk can be anticipated from prolonged therapy. By contrast, in individuals without CVD and not at high risk, large trials are needed to quantify the benefits, potential risks and cost-effectiveness of the polypill. Lonn E et al. Circulation 2010;122:2078-2088 Polypill: User Directions Take medication each day in the prescribed dosage, followed or preceded by at least 30 minutes of moderate-to-vigorous physical activity, in combination with a low-fat, lowcholesterol diet, weight management, smoking cessation, and regular visits to your physician. Franklin BA et al. AJC 2004;94:162 Dietary Priorities Associated with Cardioprotective Benefits Consume more: Consume less: • Fish and shellfish • Potatoes, refined grains, sugars • Whole grains • Processed meats • Fruits • Sweetened beverages, diet sodas • Vegetables • Grain-based desserts & bakery goods • Nuts • Fats, oil or foods containing partially • Low-fat or no fat diary products hydrogenated vegetable oils • Vegetable oils* • Salt • Water • Alcohol** * Examples include flaxseed, canola, and soybean oil ** For adults who drink alcohol, no more than moderate consumption (i.e., up to 2 drinks/day for men, 1 drink/day for women) should be encouraged, ideally with meals. CONCLUSIONS: Better CRF was associated with lower risk all-cause mortality and CHD/CVD. Participants with a MAC of 7.9 METs or more had substantially lower rates of all-cause mortality and CHD/CVD events compared with those with a MAC of less 7.9 METs. Kodama S et al. JAMA 2009;301:2024 CHD/CVD Overall 100.00 0.85 (0.82-0.88) Kodama S et al. JAMA 2009;301:2024 Prognostic Significance of Peak Exercise Capacity in Patients with CAD* • 527 men with CVD who were referred to an outpatient rehabilitation program • Measured peak VO2 during cycle ergometer testing • Average follow-up of 6.1 yrs, 33 and 20 pts died of cardiovascular and noncardiovascular causes, respectively. Highest mortality in pts who averaged ≤ 4.4 METs; There were no deaths in pts who averaged ≥ 9.2 METs. *Vanhees L et al.

MI indicates myocardial infarction. Major Findings Compared with usual care, CR ↓ total mortality by 20% and cardiac mortality by 26%. There were also substantial ↓s in TC, TGs, SBP, and self-reported cigarette smoking in the CR group, but there were no differences in HDL-C and LDL-C, DBP, or health-related QOL. The effect of CR on total mortality was independent of whether the trial was published before or after 1995, suggesting that the mortality benefits of CR persist in modern cardiology.
