Heart attack - Who and what is at risk of heart attack ?

Who Is at Risk for a Heart Attack?
 The major risk factors for a heart attack that  can control include:

• Smoking 
• High blood pressure
• High blood cholesterol
• Overweight and obesity
• An unhealthy diet (for example, a diet high in saturated fat, trans fat, cholesterol, and sodium) 
• Lack of routine physical activity
• High blood sugar due to insulin resistanceexternal link icon or diabetesexternal link icon

Some of these risk factors, such as obesity, high blood pressure, and high blood sugar tend to occur together. When they do, it's called metabolic syndrome. In general, a person who has metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone who doesn't have metabolic syndrome.
The Risk Factors that  Can't Control control include:

1. Age. The risk of heart disease increases for men after age 45 and for women after age 55 (or after menopause). 
2. Family history of early heart disease. Your risk increases if your father or a brother was diagnosed with heart disease before 55 years of age, or if your mother or a sister was diagnosed with heart disease before 65 years of age. 
3. Preeclampsia external link icon .This condition can develop during pregnancy. The two main signs of preclampsia are a rise in blood pressure and excess protein in the urine. Preeclampsia is linked to an increased lifetime risk of heart disease, including CHD, heart attack, heart failure, and high blood pressure.
