Atrial fibrillation and supraventricular tachycardia are rapid, abnormal heart rhythms that originate in the upper part of the heart. But they tend to arise at different ages, and they require different treatments.

About one in five medications taken by older people is inappropriate. Many of these are heart drugs that are potentially harmful, have no clear benefit, or aren't as good as other options. These should be stopped or switched. One common example is low-dose aspirin, which is advised only for people who've had or are at high risk for a heart attack. Other drugs that may need to be stopped or replaced include beta blockers, warfarin, and older diabetes drugs.

What we eat plays an important role in health and quality of life — but is there a single best diet? One newer choice is the largely plant-based portfolio diet, which combines aspects of highly regarded eating patterns and focuses on foods proven to lower harmful blood lipids and enhance cardiovascular health.

In a 2024 study by Harvard researchers, people who reported feeling persistently lonely had a 56% higher risk of experiencing a stroke compared with people who did not report feelings of loneliness.

High levels of lipoprotein(a), or Lp(a)—a variant of LDL (bad) cholesterol— may triple the risk of a heart attack, even among healthy people with no other known risks for heart disease.

Following a Mediterranean eating pattern is linked to longer life—a finding at least partly explained by such heart-related improvements as decreases in body mass index, inflammation, triglyceride-rich lipoproteins, and insulin resistance.

Mobile ECG devices are small, handheld devices that people can use to record a simple ECG at home. They are designed to detect heart rhythm disorders such as atrial fibrillation.

Getting an electrocardiogram (ECG) prior to undergoing noncardiac surgery should be the exception rather than the rule. About half of surgeries are low-risk and pose very little danger for the heart. Asking about a person's symptoms during physical activity—for example, whether they can walk up a flight of stairs without feeling winded—is a better gauge of their risk than the findings from an ECG. But presurgical ECGs make sense for older, inactive people with heart disease. The results can reveal signs of reduced blood flow to the heart or an unstable electrical heart rhythm that may require treatment before surgery.
