In >50% of victims, the first symptom of asymptomatic atherosclerosis is a sudden cardiac death or acute MI.

Would they have received statin therapy or more intensive statin therapy? 75% would not qualify for statin Rx. Traditional Risk Factors Miss the Majority of High Risk Patients Akosah et al.

Relying on risk factors of atherosclerosis (i.e. cholesterol & blood pressure) mislead physicians and patients. A direct assessment of atherosclerosis is needed. CONCLUSION:

1: No history of angina, heart attack, stroke, or peripheral arterial disease. 2: Population over age 75y is considered high risk and must receive therapy without testing for atherosclerosis. 3: Must not have any of the following: Chol>200 mg/dl, blood pressure >120/80 mmHg, diabetes, smoking, family history, metabolic syndrome. 4: Pending the development of standard practice guidelines. 5: High cholesterol, high blood pressure, diabetes, smoking, family history, metabolic syndrome. 6: For stroke prevention, follow existing guidelines.

Current National Preventive Care Reimbursement Policies Do Not Match the Burden of the Problem Inadequate & Disproportionate

Why do we screen for asymptomatic cancers but ignore asymptomatic CVD?
