A 2024 study suggests that for people with atrial fibrillation (afib), heart failure may be a more common complication than stroke. People with afib should be vigilant for the early warning signs of heart failure, such as feeling tired and winded.

A large observational study published in 2024 suggests that stroke isn't the biggest risk of atrial fibrillation (an abnormal heart rhythm condition). The biggest risk seems to be heart failure, a condition in which the heart is unable to pump blood effectively.

Aortic stenosis occurs when the heart's aortic valve becomes stiff and calcified, narrowing its opening so blood cannot flow normally. This can cause symptoms such as shortness of breath, fatigue, lightheadedness, fainting, and chest tightness. Neither lifestyle nor medications can slow or reverse aortic stenosis. People born with a bicuspid aortic valve are at high risk, but most people with aortic stenosis have a normal appearing valve. The only treatment is to replace the damaged valve using open heart surgery or a less invasive, nonsurgical approach called transcatheter aortic valve implantation.

Palliative care for heart failure aims to improve quality of life for patients and their families by addressing physical symptoms, and also emotional, psychosocial, and spiritual issues. This may include treating anxiety and depression in patients and supporting caregivers, who may be dealing with stress and worry. Palliative care also includes talking with patients about their personal goals and what matters most to them, which can help guide their care as the illness progresses.

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.

Even slightly elevated blood sugar levels—a condition known as pre-diabetes—may raise the risk of cardiovascular problems. But attention to weight loss and greater use of medications to lower blood pressure and cholesterol appear to reduce the risk.

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.

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.
