Take Home Messages: Physicians (1) • For LDL cholesterol, “lower is better” for preventing CV events. Mounting evidence (HPS, ASCOT, PROVE IT-TIMI 22, TNT, and now IDEAL) should likely prompt future changes in National Cholesterol Education Program and ACC/AHA cholesterol treatment guidelines. • Benefit in both ACS and stable CAD Cannon CP. JAMA 2005;294:2492-4.
Take Home Messages: Physicians (2) • Benefit dramatic on stroke: • CTT – 17% reduction in stroke with standard dose vs. placebo • IDEAL, TNT – ADDITIONAL ~20% reduction in stroke • 4. Provides support to adopt the NCEP update in 2004 • < 100 mg/dL for individuals with risk factors • < 70 mg/dL if heart disease is present. • 5. Continue research on novel approaches (HDL, CRP etc) Cannon CP. JAMA 2005;294:2492-4.
Take Home Messages: Patients (1) • For LDL cholesterol, “lower is better” for preventing heart attacks, strokes and death. Mounting evidence may prompt future changes in National Cholesterol Education Program cholesterol-level guidelines. • Know your numbers ! For both “bad” (LDL) and “good” (HDL) cholesterol Cannon CP. JAMA 2005;294:2492-4.
Take Home Messages: Patients (1) • Work with your doctor to try to reduce their LDL cholesterol to new guideline suggested levels – • < 100 mg/dL for individuals with risk factors • < 70 mg/dL if heart disease is present. This strategy is key to prevent future cardiovascular events. Cannon CP. JAMA 2005;294:2492-4.
Take Home Messages: Patients (3) • Statins are considered safe with side effects usually resolving with dose changes or switching to a different drug. • A good diet and exercise is part of the overall “heart healthy” plan. • In addition, raising the “good” (HDL) cholesterol may be beneficial on top of lowering the bad cholesterol. Cannon CP. JAMA 2005;294:2492-4.
IDEAL Editorial - JAMA • “There are now four trials and more than 27,000 patients showing that high-dose statins lower cholesterol more than regular-dose statins and provide additional benefit in preventing heart attacks,” • “These studies reaffirm the central role of lowering cholesterol as a means of reducing morbidity and mortality from heart disease.” Cannon CP. JAMA 2005;294:2492-4.
