Americans of South Asian descent are twice as likely as whites to have risks for heart disease, stroke and diabetes, when their weight is in the normal range, according to a study headed by Emory University and UC San Francisco.
Similarly, Americans of Hispanic descent were 80 percent more likely than whites to suffer from so-called cardio-metabolic abnormalities that give rise to heart disease, stroke and diabetes, compared with 50 percent more likely for those who were Chinese and African-American.
These risks include high blood pressure (hypertension), elevated glucose, low HDL, the “good cholesterol,” and high triglycerides, a fat found in blood. In the study, participants who were aged between 45 and 84, were classified as having cardio-metabolic abnormalities if they had two or more of these four risk factors.
Lifestyle Changes in Plain English:
If you don’t drink alcohol, start drinking to reduce your risk of cardiac diseases.
If you drink alcohol heavily, decrease consumption to reduce your risk of cardiac diseases.
Despite what you may be thinking this is not a racist article.
Conclusions: Treatment with rosuvastatin at a dose of 10 mg per day resulted in a significantly lower risk of cardiovascular events than placebo in an intermediate-risk, ethnically diverse population without cardiovascular disease.

This study describes the characteristics of patients referred for typical, atypical, or no angina and examines the associations between angina type, pre–cardiac catheterization stress test results, and burden of coronary atherosclerosis identified on coronary angiography.

In this short research letter we find further lack of utility for stress tests in the manner for which we are currently using them for risk stratification. The authors categorized patients referred for catheterization without known CAD to groups based on chest pain symptoms of: typical, atypical, or absent. They then looked at their stress test results, categorized as positive or negative, and found that a negative stress test did not help predict those without obstructive CAD on catheterization. Specifically, patients with typical angina symptoms and a negative stress test were the MOST likely to have obstructive CAD (74%). Clearly limited by the nature of the data presented, and the limited information given regarding the methodology in this research letter, it does further raise doubts regarding the utility of stress testing to risk stratify patients for CAD.

Conclusions Saturated fats are not associated with all cause mortality, CVD, CHD, ischemic stroke, or type 2 diabetes, but the evidence is heterogeneous with methodological limitations. Trans fats are associated with all cause mortality, total CHD, and CHD mortality, probably because of higher levels of intake of industrial trans fats than ruminant trans fats. Dietary guidelines must carefully consider the health effects of recommendations for alternative macronutrients to replace trans fats and saturated fats.
