Women may be at 20% greater risk than men of developing heart failure or dying within five years of a severe heart attack, a new study published in the American Heart Association journal Circulation states. Data from 45000 patients was analyzed by Canadian VIGOUR Centre at the University of Alberta, with focus on two types of heart attacks. They concluded that heart failure and death from severe heart attack was higher for women than men. The study noted that women are less likely to take necessary steps to prevent heart disease. It further added that most women presented symptoms of heart disease later in life compared to men.
