Can I improve my ejection fraction?
Ejection fraction is the fraction (expressed as a percentage) of the blood that the heart "ejects" out to the rest of the body when it contracts. Low ejection fraction signals one form of heart failure. An echocardiogram is the standard test to measure ejection fraction.
When heart-related pain goes unrecognized
As many as 60% of heart attacks go unnoticed when they occur. So-called silent heart attacks occur for a variety of reasons, including differences in pain perception and people not recognizing symptoms or dismissing them. People may assume heart attack symptoms are limited to the chest, but nerves in the heart can send signals to the surrounding nerves, causing pain that radiates to the stomach, back, neck, arm, or jaw. Sometimes people assume their chest pain is caused by a respiratory infection or heartburn when they're actually having a heart attack.
Harvard study: Even weekend warriors achieve heart benefits
A 2023 Harvard study found that regularly squeezing a week's worth of exercise (150 minutes) into just one or two days—a "weekend warrior" approach—is linked to the same heart-healthy benefits as daily exercise.
Genetic profiling for heart disease: An update
A polygenic risk score for heart disease is based on an analysis of more than three million common DNA variants and is expressed as a percentile. People can have zero, one, or two copies of any variant, each of which may either raise or lower the risk of coronary artery disease. Many of these variants occur in genes known to affect heart disease, such as those related to cholesterol, blood pressure, and blood clotting. Others aren't well understood and may provide targets for future research, potentially fueling new drug discovery efforts. For now, the potential benefits of this test are greatest for people under 50.
Low-dose aspirin linked to anemia
Older people who take low-dose aspirin every day may be more likely to develop anemia. Aspirin discourages blood clots, but the drug also blocks substances that help maintain and protect the delicate tissue lining the gastrointestinal tract. Long-term aspirin use can damage this protective layer, making bleeding more likely. Minor bleeding can go unrecognized and contribute to anemia, a condition marked by a reduced number of healthy red blood cells. People currently taking aspirin should check with their doctor to see if the practice still makes sense for them.
Testosterone therapy may be safe for men at risk for heart attack and stroke
A 2023 study suggests taking testosterone replacement therapy does not raise the risk for heart attacks or stroke among men with cardiovascular disease or a high risk for it, but it could increase the risk of atrial fibrillation, acute kidney injury, and pulmonary embolism.
Focusing on six food groups may help prevent cardiovascular disease
A 2023 study suggests eating enough of six categories of food common in popular heart-health diets is associated with a lower risk of cardiovascular disease, including heart attacks and strokes. The six groups are fruits, vegetables, legumes, nuts, fish, and dairy products.
Weather and air pollution linked to heart-related hospitalizations
Lower temperatures, high wind speed, atmospheric pressure, high precipitation, and high degrees of pollution may raise the risk of being hospitalized for serious heart-related conditions. Modeling these factors may help forecast future heart problems.
Statin alternative lowers heart-related deaths
The cholesterol-lowering drug bempedoic acid (Nexletol) can be a good alternative for people who can't take statins. A 2023 study found that compared with a placebo, bempedoic acid can lower the risk of heart attacks and related problems.
Heart attacks may speed cognitive decline
Accelerated cognitive decline may be more common after a heart attack, probably because the same factors that lead to narrowed heart arteries (the root cause of most heart attacks) can also cause tiny, silent strokes. An accumulation of these strokes shows up as bright areas (called white matter lesions) on an MRI scan. These lesions are markers of typical cognitive changes that occur with age. But people who have heart attacks likely have more white matter lesions and experience even greater cognitive decline.
