Signs of ‘sudden’ cardiac death may come weeks before, study finds: A new study suggests that heart attacks don’t come out of the blue – in fact, signs are usually apparent “at least a month ahead of time.” Of the approximately 360,000 out-of-hospital heart attacks that occur every year in the U.S., only 9.5% of people survive. Researchers “went back and examined medical records of men 35 to 65 years old after they had out-of-hospital attacks,” and found that 53% of the men had symptoms including chest pain, shortness of breath and dizziness, fainting or palpitations before their heart attack. “About 80 percent of symptoms happened between four weeks and one hour before the cardiac arrest, researchers said.” 

Harvard study: Eating nuts may make you live longer: Here’s more evidence that nuts are good for you. A 30-year Harvard study has found that “regular nut eaters were less likely to die of cancer or heart disease – in fact, were less likely to die of any cause.” The benefit appears to be substantial: daily nut eaters were 20% less likely to die during the study period than those who avoided the healthy snack. Plus, their risk of dying of heart disease dropped 29%. “The benefits were seen from peanuts as well as from pistachios, almonds, walnuts and other tree nuts,” though researchers did not look at how the nuts were prepared.
