Signs of 'sudden' cardiac death may come weeks before: study

Signs of approaching "sudden" cardiac arrest, an electrical malfunction that stops the heart, usually appear at least a month ahead of time, according to a study of middle-age men in Portland, Oregon. "We're looking at how to identify the Tim Russerts and Jim Gandolfinis - middle aged men in their 50s who drop dead and we don't have enough information why," said Sumeet Chugh, senior author of the study and associate director for genomic cardiology at the Cedars-Sinai Heart Institute in Los Angeles. Some 360,000 out-of-hospital cardiac arrests occur each year in the United States, largely involving middle-aged men, with only 9.5 percent surviving, according to the American Heart Association. But Chugh's study set out to determine whether signs and symptoms occurred as much as a month before sudden cardiac arrests.
