RE: Lipids and atrial fibrillation: New insights into a paradox

Posted by DrRajivKumarGmchChandigarhIndia on 23 Aug 2022 at 11:04 GMT

It is good to read perspective on the very important topic "Lipids and Atrial Fibrillation: New Insights in a Paradox".
I appreciate the authors for their research and for a good compilation.
Dyslipidemia is a known risk factor for cardiovascular diseases, but the paradoxical inverse relationship between lipid levels and atrial fibrillation as reported by the authors is provocative and an eye-opener.

The authors rightly mentiond that until the understanding of the pathophysiology behind this paradoxical observation is improved, "hyperlipidemia should be assessed as part of overall cardiovascular risk, and atrial fibrillation paradox should not outweigh this risk".

Cholesterol performs functions that are Good for Health.

Cholesterol is a precursor molecule for the synthesis of steroid hormones (cortisol & aldosterone), sex hormones (progesterone, estrogen, & testosterone) and for the making of Vitamin D Cholesterol maintains cell membranes, nerve myelin sheath and improve immune functions [1]. High cholesterol protects against infection [2], while low cholesterol predicted an increased risk of dying from gastrointestinal and respiratory diseases [3] and associated with risk of death from AIDS [4].

This observational evidence is very important for health care system and will benefits the patients from unnecessary use of "lipid lowering agents".
