Better blood sugar tracking: A benefit for heart health?

Published October 1, 2021

A continuous glucose monitor (CGM)—a small device placed on the arm or belly that measures blood sugar every few minutes—may help people with diabetes recognize the eating and exercise habits that hinder (or help) them control their blood sugar. CGM readouts, which are displayed on a smartphone or portable monitor, show your blood sugar values, trends, and the percentage of time that your blood sugar is in a "good control" range. Medicare covers CGMs for people who inject insulin at least three times a day or use an insulin pump to control their blood sugar.

Stroke prevention in atrial fibrillation: Beyond anti-clotting drugs

Published October 1, 2021

People with atrial fibrillation who develop or face a high risk of serious bleeding from anti-clotting drugs may be candidates for procedures that block or remove a part of the heart where dangerous blood clots form. About 90% of blood clots in the heart form in the left atrial appendage (LAA), a small pouch that protrudes from the top of the heart. Two procedures prevent clots from escaping from the LAA and causing a stroke. One delivers a device that blocks the opening of the LAA; the other removes most of the LAA during heart surgery done for another reason.

When someone you love has heart disease

Published October 1, 2021

People can support family members and friends with heart disease by encouraging them to do cardiac rehabilitation, a 12-week program that teaches the fundamentals of a heart-healthy lifestyle and features supervised exercise training. They can also ask about the person’s health goals and ways to help, rather than becoming frustrated if the person appears to be making poor choices. Finally, acknowledging and sharing emotions, such as fear and worry, may improve communication.

Yoga: A gateway to healthier habits?

Published October 1, 2021

Yoga addresses multiple factors that underlie heart disease, including both physical and psychological issues. Yoga can improve strength and fitness, foster better sleep, and encourage slow, deep breathing, which helps lower blood pressure and heart rate. The relaxation aspect of yoga trains the nervous system to be less reactive during times of stress. By cultivating greater mind-body awareness, yoga can help people become more in tune with their bodies and how their daily habits affect how they feel.

Harvard Health Ad Watch: Can a wearable device reduce stress?

Published September 22, 2021

Stress can affect sleep, mood, and appetite, and the long-term effects of chronic stress have been linked to health issues like cardiovascular disease, obesity, and Alzheimer's disease.

A closer look at heart disease risk

Updated September 21, 2021

Sometimes the presence of atherosclerosis, the disease underlying most heart attacks, is not clear or easily recognized, especially before a heart attack or other crisis happens. In those instances, doctors may rely on a coronary artery calcium (CAC) scan, which measures the amount of calcium in the heart's arteries, high levels of which are associated with cardiovascular disease. The CAC results can help predict a person's risk for heart attack or stroke, even if that person doesn't have obvious risk factors or symptoms.
