Half of those who need them not taking cholesterol-lowering medications

More than a third of American adults are eligible to take cholesterol-lowering medications under the current guidelines or were already taking them – but nearly half of them are not, according to a report by Centers for Disease Control and Prevention researchers published in the current issue of Morbidity and Mortality Weekly Report (MMWR). Blacks and Mexican Americans are less likely than whites to be taking cholesterol-lowering medications.

Data from 2007 through 2014 show a decline in the number of Americans with high blood levels of cholesterol. There also has been a recent increase in the use of cholesterol-lowering medications. But a high blood level of LDL cholesterol – also known as “bad” cholesterol – remains a major risk factor for heart disease and stroke in the United States. (Read More)

The U.S. government is poised to withdraw longstanding warnings about cholesterol

The nation’s top nutrition advisory panel has decided to drop its caution about eating cholesterol-laden food, a move that could undo almost 40 years of government warnings about its consumption.

The group’s finding that cholesterol in the diet need no longer be considered a “nutrient of concern” stands in contrast to the committee’s findings five years ago, the last time it convened. During those proceedings, as in previous years, the panel deemed the issue of excess cholesterol in the American diet a public health concern.

The finding follows an evolution of thinking among many nutritionists who now believe that, for healthy adults, eating foods high in cholesterol may not significantly affect the level of cholesterol in the blood or increase the risk of heart disease.

The greater danger in this regard, these experts believe, lies not in products such as eggs…(Read More Here)

Prognostic Value of Fasting vs. Non-Fasting Low Density Lipoprotein Cholesterol Levels on Long-term Mortality

National and international guidelines recommend fasting lipid panel measurement for risk stratification of patients for prevention of cardiovascular (CV) events. Yet, the prognostic value of fasting vs. non-fasting low density lipoprotein cholesterol (LDL-C) is uncertain.

Patients enrolled in the National Health and Nutrition Survey III (NHANES-III), a nationally representative cross-sectional survey performed between 1988 to 1994, were stratified based on fasting status (≥8 hours or <8 hours) and followed for a mean of 14.0 (±0.22) years…

…Non-fasting LDL-C has similar prognostic value as that of fasting LDL-C. National and international agencies should consider re-evaluating the recommendation that patients fast before obtaining a lipid panel. (Learn more here)
