Uncommon form of heart attack likely runs in family: study

By Sharon Begley NEW YORK (Reuters) - Although oncologists increasingly distinguish breast, lung, and other cancers by their molecular drivers, cardiologists have lagged behind in efforts to do something similar for heart disease. A study published on Monday could help remedy that: Researchers have found evidence of a genetic basis for an enigmatic kind of heart attack that preferentially strikes young women. Just as breast cancers driven by one mutation need different chemotherapy than those driven by another, many heart attacks likely have different causes and so need different treatment. "The key to precision medicine will be splitting instead of lumping diseases together," said cardiologist Joseph Loscalzo of Brigham and Women's Hospital and Harvard Medical School.
