After surgery unrelated to the heart, a diagnosis of atrial fibrillation (afib) may be more common than previously thought. These cases, which may constitute 13% of new afib diagnoses, appear to be undertreated.

The American Heart Association added sleep to its list of factors for cardiovascular health. The others are a healthy diet; physical activity; low levels of nicotine exposure; and healthy levels of weight, cholesterol, blood sugar, and blood pressure.

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.

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.

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.

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.

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 2022 study found that women are more likely than men to have "generalized" stroke symptoms such as weakness and confusion, in addition to classic signs such as speech or movement problems.

A randomized trial published May 14, 2022, in The Lancet found that people with heart disease who ate a Mediterranean diet for seven years had a 26% lower risk of having a heart attack or stroke, compared with people who ate a low-fat diet.

Recent guidelines suggest a blood pressure reading of less than 120/80 mm Hg as normal. But the ideal number for individuals depends on their individual goals and whether they also have a chronic condition, such as heart disease or kidney disease.
