Relationship benefit in women with IHD
As reported in BMC Medicine, women who were married or living with a partner had a decreased risk of mortality (RR=0.72) after the first ischemic heart disease (IHD) event compared to women who were not married or living with a partner. The study involved 734626 women with no history of IHD who were followed for 8.6 y; there were 30747 women with a first IHD event and 2148 deaths.
Muscle strength in adolescence decreases CVD risk
As reported in BMC Medicine, adolescents (n=38588) with the highest tertile of muscle strength had a decreased risk of CVD (HR=0.88) compared to adolescents with the lowest tertile of muscle strength after 42 y of follow-up. Of note, low muscle strength in adolescence by itself had no effect on CVD risk in middle age (HR=0.99). In contrast, high muscle strength in adolescence significantly decreased the risk of CVD in middle age (HR=1.31).
Vitamin D supplementation improves ejection fraction
As reported in Nutrition, Metabolism, and Cardiovascular Diseases, vitamin D supplementation (4000 IU/d of cholecalciferol x 6 months) of vitamin D-deficient heart failure patients (n=23) resulted in an increase in the ejection fraction compared to placebo (6.7 vs. -4.3%).
