Study suggests that HDL or 'good' cholesterol is less beneficial than previously thought, especially for Black adults - CNN

CNN  — 

High-density lipoprotein, oregon HDL, cholesterin – often referred to arsenic the “good” cholesterin – whitethorn not beryllium arsenic utile successful predicting the hazard of bosom illness and protecting against it arsenic antecedently thought, according to caller researched funded by the National Institutes of Health.

A survey from the 1970s recovered that precocious levels of HDL cholesterin attraction were associated with debased coronary bosom illness risk, a nexus that has since been wide accepted and utilized successful bosom illness hazard assessments. However, lone White Americans were included successful that study.

Now, research published Monday successful the Journal of the American College of Cardiology recovered that debased levels of HDL cholesterin were associated with higher hazard of bosom onslaught among White adults, but the aforesaid was not existent among Black adults. Also, higher levels of HDL cholesterin were not recovered to trim the hazard of cardiovascular illness for either group.

“It’s been good accepted that debased HDL cholesterin levels are detrimental, careless of race. Our probe tested those assumptions,” said Nathalie Pamir, a elder writer of the survey and an subordinate prof of medicine astatine the Knight Cardiovascular Institute astatine Oregon Health & Science University, Portland, successful a news release. “It could mean that successful the future, we don’t get a pat connected the backmost by our doctors for having higher HDL cholesterin levels.”

The researchers utilized information from thousands of radical who were enrolled successful the Reasons for Geographic and Racial Differences successful Stroke (REGARDS) cohort. Participants were astatine slightest 45 years aged erstwhile they enrolled successful the programme betwixt 2003 and 2007, and their wellness was analyzed implicit an mean of 10 years.

The researchers recovered that precocious levels of low-density lipoprotein (LDL) cholesterin and triglycerides “modestly” predicted bosom illness hazard among some Black and White adults.

But they suggest that much enactment is needed to recognize what’s driving the radical differences successful the nexus betwixt HDL and bosom illness risk.

And successful the meantime, existent objective assessments for bosom illness hazard “may misclassify hazard successful Black adults, perchance hindering optimal cardiovascular illness prevention and absorption programs for this group,” they wrote.

CNN Medical Correspondent Dr. Tara Narula, subordinate manager of the Lenox Hill Women’s Heart Program, said the survey “highlights the precise important request for much race- and ethnic-specific probe and that determination is not a one-size-fits-all approach. Additionally, this probe emphasizes the continued request to amended that precocious levels of HDL are not a escaped walk and absorption indispensable beryllium placed connected controlling elevated LDL and different known markers of accrued cardiovascular risk. “
