An obese, middle-aged man is running to catch a bus. Suddenly, he clutches his chest, falls to the ground and dies of a massive heart attack. It turns out that he's a smoker and a diabetic, has high blood pressure, eats a diet high in saturated fat and low in leafy green vegetables, pours salt on everything, drinks too much beer, avoids exercise at all costs and has a father, grandfather and two uncles who also died young of heart attacks. So what killed him? Most people are savvy enough about health risks to know this is a trick question.

Heart patients who used common pain relievers called NSAIDs even briefly are at much higher risk of having a repeat heart attack or of dying than those who stay away from the drugs, which include such widely used over-the-counter medications as ibuprofen and naproxen, a new study concludes. The research, published Tuesday in the American Heart Assn.'s journal, Circulation , suggests that for patients who have suffered a heart attack, even short-term use of NSAIDs, or nonsteroidal anti-inflammatory drugs for headaches, back pain or sore muscles and joints is a bad idea.

Heart attacks can be difficult to diagnose. Moreover, doctors often can't tell a cardiac patient whether he or she is likely to suffer another heart attack. A new test to detect a particular substance in the blood may help with that problem but, if adopted for widespread use, it could also dramatically raise the number of heart attack diagnoses. In the study, published Tuesday in the Journal of the American Medical Assn ., researchers reported success using a more sensitive test to identify troponin, a cardiac muscle protein.

Hall of Fame manager Tommy Lasorda, who retired as Dodgers manager after a heart attack in 1996, had a “mild heart attack” Monday while in New York City. He is 84, and reports say he had a stent inserted to clear a blocked coronary artery and is resting stably and comfortably at a hospital in New York City. What is a “mild heart attack,” anyway? “A 'mild heart attack' is like being a little bit pregnant -- it's still a heart attack,” said cardiologist Dr. Robert Greenfield, chairman of medicine at Orange Coast Memorial Medical Center in Fountain Valley.

It's long been an article of faith that human heart muscle, once damaged, cannot regenerate. But findings from two clinical trials, presented Monday at the American Heart Assn.'s Scientific Sessions in Orlando, Fla., suggest that isn't the case. Two teams of researchers found that stem cells harvested from a patient's own heart were able to reverse damage from a heart attack. Dr. Roberto Bolli, director of the division of cardiology at the University of Louisville in Louisville, Ky., and colleagues presented initial results from an ongoing clinical trial that treated 16 heart attack patients with infusions of cardiac stem cells that had been harvested from their own hearts during bypass surgery. Their trial was also described in an article published simultaneously by the journal The Lancet . Dr. Eduardo Marbán, director of the Cedars-Sinai Heart Institute in Los Angeles, discussed final results from another Phase 1 trial in which doctors harvested cardiac tissue using a minimally invasive technique, cultivated stem cells from the tissue and administered them to 17 study subjects.

The toll of a heart attack may be more than just physical. Patients who suffer heart attacks could also suffer from post-traumatic stress disorder -- which could raise the risk of another heart attack, according to a study in the journal PLoS ONE. Post-traumatic stress disorder, or PTSD, is an anxiety disorder that often develops after a traumatic event involving the threat of injury or death, according to the National Institutes of...
