Medications such as aspirin, statins, ACE inhibitors, and beta blockers are prescribed to certain patients to lower the chance of a first or repeat heart attack. New research shows that they also may reduce the severity of attacks that do occur.

A review of 31 studies indicated that calcium intake of 2,500 milligrams or less per day does not increase the risk of developing heart disease in healthy adults.

Reduce your dependence on medications with these strategies.

More than a third of all adults in the United States have high blood pressure—a systolic pressure (the top number in a reading) of at least 140 millimeters of mercury (mm Hg), or a diastolic pressure (the bottom number) of at least 90 mm Hg, or both. The condition injures blood vessel walls and forces the heart to work harder, increasing the risk for heart disease and stroke.

Taking medication to treat high blood pressure is just part of the solution.

An abnormal heart rhythm — when your heartbeat is too slow, too fast, or irregular — may be a fleeting, harmless event. But it may also be a symptom of a more serious heart condition. One of these common abnormal heart rhythms, known medically as arrhythmias, is atrial fibrillation.

Atrial fibrillation

In atrial fibrillation (afib, for short), the heart's upper chambers, or atria, quiver instead of beating normally. The result is a fast, irregular heartbeat, which may lead to dizziness and fatigue but is often symptomless. A related condition is called atrial flutter.

Research suggests that raising good cholesterol beyond a certain point doesn't offer any extra benefit for the heart.

When it comes to cholesterol, it's mostly about the numbers. You want less of the "bad" low-density lipoprotein (LDL) cholesterol and more of the "good" high-density lipoprotein (HDL) kind. This combination is often associated with a lower risk of cardiovascular disease. Sounds simple—and it is, for the most part. But while most attention is spent on driving down bad LDL, you still have to keep your eyes on the good HDL, as some research suggests that after a certain threshold, higher levels don't offer extra protection.

The ideal numbers

New research has linked heart tissue damage to blood pressure treatments that drive diastolic pressure (the bottom number in a reading) too low. 

A majority of men do not talk about resuming their sex life after a heart attack, which may lead to sexual problems like lack of interest and erectile difficulties. Researchers say that before being discharged from the hospital, men should expect to have a conversation with their physician about when it’s okay to resume all regular activities, including sex. If the topic does not come up, men should take the initiative.
