‘Promising Signals’ With Cocoa Flavanols to Reduce CV Events?

Results of a large, randomized trial of a cocoa flavanol supplement showed a trend toward a reduction in total cardiovascular events, although the reduction did not reach statistical significance in comparison with placebo. However, some secondary endpoints, including cardiovascular disease (CVD) death, did show significant results the researchers called “promising” and that warrant further investigation, … Read more

Exercise Provides Twice the CV Benefit in Anxiety, Depression

Meeting guideline-recommended exercise targets is associated with a reduced risk of cardiovascular disease (CVD) in everyone, but the benefits may be particularly clear for people with anxiety and depression, a new analysis suggests. In a study of more than 50,000 adult patients with or without CVD or risk factors who were followed for a median … Read more

‘Voice Biomarker’ Shows Progress in CAD Risk Assessment

Vocal characteristics that can’t actually be heard, discernible only by computer, might help identify individuals with confirmed or suspected heart disease who are at increased risk for a cardiovascular (CV) event over the next several years, a prospective study suggests. The research is only the latest to suggest a potential role for “voice biomarkers” — … Read more

Calcium Scores May Predict Sudden-Death Risk in Preclinical CAD

The risk for sudden cardiac death (SCD) climbs steadily in tandem with coronary artery calcium (CAC) burden, independent of more conventional risk factors, in primary-prevention patients considered low- to intermediate-risk, researchers say. The findings, based on a large cohort study, strengthen the case for initial CAC imaging as a gatekeeper to further testing in such … Read more
