New York: Sudden tightness in your chest? Shooting pain down your left arm? Everyone knows that could be a heart attack. But what if symptoms aren't so sudden? When symptoms come on slowly, heart attack patients are less likely to get to a hospital quickly, according to a study in Dublin, Ireland.
"We didn't know that most heart attacks start off with mild and slow symptoms," said Sharon O'Donnell, who led the study at the University of Dublin, Trinity College in Ireland. |
