Vitamin D Supplements May Improve Cardiac Function in Heart Failure

Taking vitamin D supplements may improve cardiac function in chronic heart failure patients, according to a study presented on April 4 at ACC.16 in Chicago and published simultaneously in the Journal of the American College of Cardiology.

In this randomized, placebo-controlled double-blind trial, Klaus K. Witte, MD, FACC, and colleagues studied 223 patients with chronic heart failure due to secondary left ventricular (LV) systolic dysfunction and vitamin D deficiency ((25(OH) vitamin D3 <50nmol/L (<20ng/mL)). 20ng/mL)). Participants were either allocated to one year of vitamin D3 supplementation (4000 IU (100μg) 25(OH)D3 daily) or matching non-calcium-based placebo. A total of 163 patients completed the study. The primary endpoint was change in six-minute walk distance from baseline to 12 months, and the secondary endpoint included the change in left ventricular ejection fraction at one year. - See more at: http://www.acc.org/latest-in-cardiology/articles/2016/03/23/18/25/mon-2pm-vindicate-vitamin-d-supplementation-improves-cardiac-function-in-patients-with-chronic-hf-acc-2016?w_nav=LC#sthash.x1j5whSM.dpuf http://www.acc.org/latest-in-cardiology/articles/2016/03/23/18/25/mon-2pm-vindicate-vitamin-d-supplementation-improves-cardiac-function-in-patients-with-chronic-hf-acc-2016?w_nav=LC
