When a heart attack begins, the time it takes until the blockage in a coronary artery is cleared is critical in preventing further damage to the heart, a new study warns.

The amount of damage is directly related to how long it takes from the start of a heart attack to when patients receive an artery-clearing procedure called percutaneous coronary interventio...

People with metabolic syndrome and the skin condition psoriasis are at especially high risk for heart attack and stroke, a new study warns.

"It's very difficult to understand exac...

Fewer U.S. heart attack survivors are having another heart attack within a year, a new study finds.

Rates of recurrent heart attacks, hospitalization for heart failure and deaths within a year have gone down in heart attack survivors, according to the study published Sept. 21 in the journal Circulation. However, the rates are still high, researchers said.

The study an...

Many heart attack survivors worry that resuming sex too soon afterwards might trigger another attack. But new research suggests the opposite may be true.

Research out of Israel finds that resuming a normal sex life in the months after a heart attack may actually boost survival.

Lead researcher Yariv Gerber believes part of the benefit could lie in a person's mindset.

Most people now know that COVID-19 can cause blood clots, potentially leading to paralysis, stroke, heart attack and death.

While it's not clear precisely how SARS-CoV-2 causes clots, a new study suggests that the amount of a particular protein -- called factor V -- in a patient's blood may have something to do with it.

In March, researchers at Massachusetts General Hospit...

If you have experienced a heart attack and you have an adversarial personality, new research suggests you might want to consider an attitude adjustment.
