Stroke prevention in atrial fibrillation: Beyond anti-clotting drugs

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.

Exercise appears to lower atrial fibrillation and stroke risk

The link between exercise and atrial fibrillation (afib) and stroke prevention is now a little clearer, thanks to a Harvard study. It offers strong evidence that 150 minutes per week of moderate-to-vigorous physical activity is associated with a reduced risk for atrial fibrillation and stroke. Researchers aren’t surprised, since exercise helps the chambers of the heart contract and relax, while being sedentary increases afib and stroke risk. Other ways to ward off afib and stroke include treating sleep apnea, quitting smoking, and drinking only in moderation.

Do people who have COVID-19 go on to develop other diseases?

Evidence suggests that people who recover from COVID-19 have an increased risk for developing new health problems, including heart attacks, high blood pressure, diabetes, high cholesterol, muscle inflammation, blood clots that travel to the lungs, strokes from clots or hemorrhages, or psychosis. This is in addition to permanent damage that can result from having COVID, including damage to the lungs, heart, kidneys, brain, or other organs; and debilitating fatigue, difficulty thinking, and other symptoms that make it hard to function normally at work or at home.

Wearable devices may encourage enough exercise to prevent afib

Getting the recommended amount of physical activity appears to lower the risk of atrial fibrillation (afib), a heart rhythm disorder that raises the risk of stroke.

Early menopause linked to higher risk of stroke

Women who go through menopause before they turn 40 may be more likely to have a stroke than women who undergo the transition between 50 and 54, according to a study published in the August 2021 issue of the journal Stroke.

Shingles vaccine may also reduce stroke risk

The shingles vaccine was associated with a 10% to 20% lower risk of stroke among adults ages 66 and older, according to a recent study.

Supplements to prevent heart disease and cancer not justified

The U.S. Preventive Services Task Force found insufficient evidence for using most vitamin and mineral supplements to prevent heart disease and cancer in most healthy adults.

High blood pressure? Treat the risk, not the number

People with a high risk for heart attacks and strokes might benefit from taking blood pressure–lowering medications, even if their blood pressure is in the normal or "high normal" range and they have no clear signs of cardiovascular disease.

Reducing heart risks in the wake of breast cancer treatment

Hormone therapy is a highly successful breast cancer treatment for women, but it can elevate cardiovascular risk. Women can reduce those risks by being vigilant about their heart health and working closely with their doctors. Women who have taken or are taking these medications as part of breast cancer treatment should focus on adopting a healthy lifestyle, exercising regularly, and keeping close tabs on their blood pressure, cholesterol levels, and blood sugar levels.

Look inside your heart

The traditional measures to gauge heart disease risk don’t always tell the whole story. Sometimes more medical information is needed. An increasingly used test to predict a person’s risk for heart attack or stroke is a coronary artery calcium scan. It measures the amount of calcified plaque in the heart’s arteries, high levels of which suggest higher overall plaque buildup. The number can determine if people should begin statin therapy and make additional lifestyle changes.
