A research on cardiovascular disease in the United States reveals that 1.5 million cases of heart attacks occur each year with 500,000 resulting into deaths. Heart attack, which is the leading cause of death among men and women in the US, claims about 50 per cent of deaths occurring within an hour outside a hospital and about 6 per cent to 9 per cent of mortality rate for those who make it to the hospital. Studies show that heart attacks commonly occur on Monday mornings and usually during early morning hours when the blood platelets are more sticky.
