Why does screening for the prevention of heart attacks need to look beyond cholesterol and traditional risk factors?

Because traditional risk factor based screening fails miserably in identifying the Vulnerable Patient.

Of 136, 905 patients hospitalized with CAD, 77% had normal LDL levels below 130 mg/dl Modified from Sachdeva et al.

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

CONCLUSION: Status Quo Unacceptable

In summary: Two Major Problems Exist in Cardiology Today: 1 - Inaccurate Individualized Risk Assessment 2 - Inadequate Monitoring of Response to Therapy

SHAPE Guidelines Published

SHAPE v. s. Status Quo Existing Guidelines (Status Quo): • Screen for Risk Factors of Atherosclerosis • Treat Risk Factors of Atherosclerosis The SHAPE Guidelines: • Screen for Atherosclerosis (the Disease) Regardless of Risk Factors • Treat based on the Severity of the Disease and its Risk Factors

1: No history of angina, heart attack, stroke, or peripheral arterial disease. 2: Population over age 75 y 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 mm. Hg, 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.

TEXAS HEART ATTACK PREVENTIVE SCREENING LAW Sec. A 1376. 003. AAMINIMUM COVERAGE REQUIRED. (a) A health benefit plan that provides coverage for screening medical procedures must provide the minimum coverage required by this section to each covered individual: (1)who is: (A)a male older than 45 years of age and younger than 76 years of age; or (B)a female older than 55 years of age and younger than 76 years of age; and (2)who: (A)is diabetic; or (B)has a risk of developing coronary heart disease, based on a score derived using the Framingham Heart Study coronary prediction algorithm, that is intermediate or higher. (b)the minimum coverage required to be provided under this section is coverage of up to $200 for one of the following:

TEXAS HEART ATTACK PREVENTIVE SCREENING LAW noninvasive screening tests for atherosclerosis and abnormal artery structure and function every five years, performed by a laboratory that is certified by a national organization recognized by the commissioner by rule for the purposes of this section: (1) computed tomography (CT) scanning measuring coronary artery calcification; Or (2) ultrasonography measuring carotid intima-media thickness and plaque.

Comparing to the treatment of a heart attack, its prevention is woefully under-invested.

The ultimate preventive strategies must be directed towards the different levels of primary prevention (i. e. prevention of atherosclerosis risk factors in the entire population, mass treatment of atherosclerosis in a smaller at -risk population, and preemptive prevention of events in further smaller pre-symptomatic population. The 1 st SHAPE guideline is directed at the early detection and treatment of subclinical atherosclerosis and fills the gap in the existing guidelines.
