The Relationship Between Vitamin D Status and Cardiovascular Diseases.

Curr Probl Cardiol 2021 Mar 19;46(7):100836. Epub 2021 Mar 19.

Liverpool Centre for Cardiovascular Science, University of Liverpool and Liverpool Heart and Chest Hospital, Liverpool, UK; Department of Cardiothoracic Surgery, Liverpool Heart and Chest Hospital, Liverpool, UK. Electronic address:

With cardiovascular conditions being a leading cause of mortality and morbidity globally, several studies have identified that there is an important correlation between the level of Vitamin D and cardiovascular diseases, including an increased risk of hypertension, heart failure, and coronary artery diseases. Current published studies are in the form of both in vivo and in vitro studies and they primarily showed the evidence of how Vitamin D can downregulate Renin-Angiotensin-Aldosterone system activity and therefore providing a cardioprotective role. Nevertheless, most of these studies are observational, and there yet to be large-scale randomized controlled trials which would increase the evidence of the findings. Read More

Screening for Vitamin D Deficiency in Adults: US Preventive Services Task Force Recommendation Statement.

JAMA 2021 04;325(14):1436-1442

Tufts University School of Medicine, Boston, Massachusetts.

Importance: Vitamin D is a fat-soluble vitamin that performs an important role in calcium homeostasis and bone metabolism and also affects many other cellular regulatory functions outside the skeletal system. Vitamin D requirements may vary by individual; thus, no one serum vitamin D level cutpoint defines deficiency, and no consensus exists regarding the precise serum levels of vitamin D that represent optimal health or sufficiency.

Objective: To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening for vitamin D deficiency, including the benefits and harms of screening and early treatment. Read More
