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.

A closer look at alcohol's effect on heart health

Excessive drinking can contribute to high blood pressure, obesity, and stroke, while moderate drinking (no more than one drink per day for women and two drinks or fewer per day for men) is linked to a lower risk of heart problems. One possible mechanism might be stress reduction. Brain scans of people who reported light to moderate drinking show less activity in the part of the brain that responds to stress, compared with the scans of people who abstained or drank very little. Stress not only raises blood pressure and heart rate but also triggers inflammation that causes plaque buildup, which contributes to heart attacks.

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.

Don't be fooled by TIA symptoms

Ignoring the warning signs of a ministroke can lead to a major stroke at a later time. People should be evaluated right away for symptoms such as speech and vision problems or weakness in an arm or leg.

Sleep problems may raise the risk of stroke

A 2023 study suggests that sleep problems such as snoring, snorting, or getting too much or little sleep can significantly raise the odds of having a stroke.

The (almost) last word on alcohol and health

Research into the health benefits of alcohol has not provided a clear answer. Some findings suggest that alcohol helps protect against heart disease and lowers the risk of heart attacks and strokes, and drinkers tend to live longer than nondrinkers. Other studies say these benefits are less clear. If you don't drink alcohol now, there are no health reasons to start drinking. If you do enjoy it, it's best to have no more than 2 drinks in the same day.

What is a silent stroke?

Most strokes are caused by a clot that blocks a blood vessel in the brain. Those that damage small areas of brain tissue that don't control any vital functions are known as silent strokes because they don't cause any noticeable symptoms.

When walking leads to leg pain

Peripheral artery disease (PAD), which occurs when fatty deposits clog arteries outside the heart, is underrecognized and potentially dangerous. The hallmark symptom is leg pain that occurs with exercise, called intermittent claudication. PAD is more common among people who are older, who smoke, and who have diabetes. The recommended treatment involves short periods of walking interspersed with rest periods when pain occurs. Walking increases blood flow in the leg's smaller arteries and helps create new channels to move blood around the blockages; it also helps discourage new blockages.
