Study finds chronically disrupted sleep may increase risk for heart disease

Vanderbilt research found that sleep irregularity — chronically disrupted sleep and highly variable sleep durations night after night — may increase the risk for atherosclerosis.

BMI genetics influence heart function

Vanderbilt researchers have discovered that a genetic predisposition to elevated body mass index increases the risk of diastolic dysfunction — a cardiac condition that can lead to heart failure.

Sex & race & door-to-ECG time

More than a third of patients presenting at the emergency department with a suspected heart attack have a “delayed” ECG measure of heart function, with Black patients, females and non-English speakers more likely to experience delays.

Vitamin D impact on disease biomarkers

In a randomized controlled trial, vitamin D supplementation did not improve biomarkers for cardiovascular and metabolic disease.

Heat for hypertension in autonomic failure

Heat therapy could offer a novel nonpharmacologic approach for treating the overnight hypertension that affects patients with autonomic failure.
