Coronary Artery Calcium Scan Embraced By New AHA/ACC Cholesterol Guidelines: Will Insurance Coverage Follow?

Thank you Dr. Pearson.

The Skeptical Cardiologist

The skeptical cardiologist has been utilizing coronary artery calcium (CAC) scans to help decide which patients are at high risk for heart attacks, and sudden cardiac death for the last decade. As I first described in 2014, (see here) those with higher than expected calcium scores warrant more aggressive treatment and those with lower scores less aggrressive treatment.

Although , as I have discussed previously, CAC is not the “mammography of the heart” it is incredibly helpful in sorting out personalized cardiovascular risk. We use standard risk factors like lipids, smoking, age, gender and diabetes to stratify individuals according to their 10 year risk of atherosclerotic cardiovascular disease (ASCVD) but many apparent low risk individuals (often due to inherited familial risk) drop dead from ASCVD and many apparent high risk individuals don’t need statin therapy.

Previously, major guidelines from organizations like the AHA and the ACC did not recommend…

Abdominal Aortic Calcification Among Individuals With and Without Diabetes: The Jackson Heart Study

In the Jackson Heart Study (JHS), we examined the association of diabetes with abdominal aortic calcification (AAC) among African Americans. Among included individuals (n = 1,664), the mean age was 57 (± 11) years, 69% were female, and 18.3% had diabetes (based on fasting blood glucose [FBG], HbA1c, use of glucose-lowering medications, or physician diagnosis). The median AAC and coronary artery calcification (CAC) scores were 904.15 (interquartile range 0–1093.10) and 0 (0–96.19), respectively. The prevalence of any AAC or CAC was 69% and 49%, respectively. Individuals with diabetes were older, had higher BMI, had higher systolic blood pressure and prevalence of hypertension, had lower HDL levels, were less affluent or physically active, had poorer nutritional intake, and had higher levels of hs-CRP.
