The subject of alcohol and heart attacks is important because the major cause of death in many countries is heart disease
Research indicates that moderate drinkers are less likely to suffer heart attacks than are abstainers or heavy drinkers.
An exhaustive review of all major heart disease studies has found that "alcohol consumption is related to total mortality in a U-shaped manner, where moderate consumers have a reduced total mortality compared with total non-consumers and heavy consumers.
Research also reports that the risk of a heart attack among moderate drinkers with diabetes is 52 percent lower than among nondrinkers and that the risk of dying in the four years after a heart attack is 32 percent lower among those who were moderate drinkers in the year before the attack.
