What is a bubble study?

A bubble study is a test done in conjunction with an echocardiogram to check for the presence of a tiny opening between the heart's upper chambers called a patent foramen ovale. Such an opening could explain how an unexpected stroke happened.

More protection for your heart? It's just a shot away

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

Can self-employment promote better cardiovascular health for women?

Being self-employed can offer advantages like flexibility and autonomy in a person's work life. Now, data from a long-term health study suggests that self-employment may provide another benefit for some women: improved health outcomes.

The case of the bad placebo

A trial from 2019 showed a medication dramatically reduced triglyceride levels in participants, but subsequent analysis found that the placebo used in the trial may have negatively affected those assigned to take it.

The lowdown on "good" cholesterol

Long touted as beneficial for heart health, high-density lipoprotein (HDL) is more complicated than experts once thought. Some forms of HDL grab cholesterol from the bloodstream and other tissues and transport it to the liver, where it's recycled or disposed, but other types are neutral or perform the opposite action. Most drugs that raise HDL don't seem to prevent heart disease, and very high HDL levels may even be linked to a higher risk.

Putting potassium in perspective

Too much or too little potassium can harm the heart. Diet, medications, and kidney function can affect the body's potassium level. Dietary potassium helps keep blood pressure in a normal range, but most Americans don't consume enough of this mineral. However, people taking medications that raise potassium levels—which includes certain drugs to treat high blood pressure and heart failure—should avoid salt substitutes made with potassium chloride.

A lower blood pressure goal benefits some older adults

Taking an aggressive approach to lower high blood pressure with more medication can help many older adults reduce their risk for heart attacks, stroke, and heart failure. But they need to weigh the benefits with the potential side effects of extra medication.

Meal of the month: Hearty salad supper

A big, hearty salad can provide the recommended daily dose of vegetables. Adding other filling ingredients such as starches and proteins turns a salad into a healthy, satisfying meal.

Long periods of sitting tied to higher risk of stroke

Sitting too much can boost stroke risk. But adding more movement—even low-effort activity such as doing household chores—may help lower that risk.

Could anger and depression raise the risk of afib?

Psychological issues such as anger, anxiety, depression, and work stress are associated with a greater likelihood of the heart rhythm disorder known as atrial fibrillation, according to a 2022 study.
