People suffering from stress cardiomyopathy, or "broken-heart syndrom", seem to be havinf a heart attack: they have chest pain, fluid in the lungs, shortness of breath and heart failure. But although the ability of heart to pump is singificantly reduced and the heart muscle is weakened, it is not killed, or infarcted, as in a classic attack.
