After age 50, about the age of natural menopause, nearly half of all female deaths are due to some form of cardiovascular disease. There are a number of risk factors for cardiovascular disease. Some are modifiable, like smoking, excess weight, excess alcohol intake, sedentary lifestyle, diabetes, high blood pressure, and cholesterol for example. Other risk factors are non-modifiable, like family history of heart attack or stroke, ethnic background, age, and sex. Women seem to be at higher risk of heart disease after menopause due to decrease in estrogen levels and blood pressure tends to increase with menopause.
