Direct-to-consumer genetic tests for heart disease

Direct-to-consumer genetic tests can screen for rare heart conditions that arise from variants in a single gene (such as cardiomyopathies) as well as common conditions influenced by many thousands of gene variants (such as coronary artery disease).

Cannabis and heart concerns: A closer look

Cannabis use is rising among older adults, who mostly use cannabis edibles such as gummies for relaxation and sleep. While smoking cannabis may raise heart attack risk, the cardiac effects of consuming cannabis in food or drinks are less well understood.

Because the shock of cold water on the skin can raise heart rate and blood pressure, people with cardiovascular disease (especially heart rhythm abnormalities) should avoid the practice.

Plant-based oils are better than butter for your heart
