What are risk factors for a heart attack?

Early and ongoing heart disease prevention is important. At least 80 percent of deaths from heart disease and stroke could be avoided, according to the World Heart Federation. Many coronary heart disease (CHD) risk factors are preventable and controllable, even if you or someone you love already has CHD. Common risk factors that increase the chances of having a heart attack include:

  • High blood pressure
  • High cholesterol
  • Diabetes
  • Smoking and secondhand smoke
  • Previous heart attack or stroke

Other risk factors include:

  • Overweight and obesity
  • Poor diet, including foods high in salt, fat, cholesterol, and sugar, and low in fruits and vegetables
  • Physical inactivity

The major risk factors for a heart attack (cardiac risk factors) are high blood pressure, high cholesterol, diabetes, tobacco use and family history of premature coronary artery disease. Some of the minor risk factors include being overweight and obese, high stress levels and a sedentary lifestyle.

Classic risk factors for a heart attack: 

  • age (men over 45, women over 55)
  • smoking exposure
  • high blood pressure
  • high cholesterol
  • diabetes
  • family history of heart disease (parents, siblings or grandparents) in male relatives younger than 55 or female relatives younger than 65

Emerging risk factors for a heart attack:

  • obesity
  • lack of physical activity
  • chronic inflammatory diseases (lupus, rheumatoid arthritis, psoriasis)

Risk factors for a heart attack include age and genetic predisposition for heart disease, which are risk factors that cannot be modified. True genetically related predisposition, found in about 10 percent of the population, needs to be distinguished from the common “family history,” indicating presence of heart disease in the family due to poor lifestyle habits such as smoking, high cholesterol diets and lack of physical activity. Most risk factors for a heart attack can be modified and controlling them would dramatically decrease the odds of having a heart attack. Modifiable risk factors include:

  • smoking
  • diabetes
  • hypertension
  • high cholesterol
  • low “good” HDL cholesterol
  • sedentary lifestyle (no regular physical activity)
  • heart unhealthy diet

Some risk factors for heart attack are ones you're born with and cannot be changed. Other risk factors can be modified, treated or controlled through medications or lifestyle change. The more risk factors you have, the greater your chance of developing coronary heart disease. The following are risk factors for heart attack:

  • increasing age (males over 45, females over 55)
  • heredity and family history
  • diabetes
  • smoking
  • high blood cholesterol levels
  • physical inactivity
  • obesity or being overweight

The risk factors for heart attack are the following:

  • smoking
  • hypertension (high blood pressure)
  • high cholesterol
  • diabetes
  • family history of premature coronary artery disease (CAD)
  • age (males over 45, females over 55)

Certain factors, called coronary risk factors, increase your risk of a heart attack. These factors contribute to the unwanted buildup of deposits (atherosclerosis) narrowing arteries including those to your heart. Coronary risk factors include:

  • tobacco smoke
  • high blood pressure
  • high blood cholesterol or triglyceride levels
  • lack of physical activity
  • obesity
  • diabetes
  • stress
  • alcohol
  • family history of heart attack
  • higher levels of homocysteine, C-reactive protein and fibrinogen

While reducing or eliminating risk factors can reduce your chance of having a first or a second heart attack, risk factors such as heredity and gender cannot be eliminated. Men are generally at greater risk to have a heart attack than women. For women the risk increases after menopause and usually after age 55. If your father had heart disease before age 55 or your mother before age 65, you are at greater risk for developing heart disease.

Heart attack risk increases if you engage in certain lifestyle choices like smoking and drug use. Other risk factors include low physical activity, obesity and diabetes. Heart attack risk also increases if you have high blood pressure and high blood cholesterol. All of these factors contribute to the accumulation of fatty deposits, called plaques, in the inside of the coronary artery walls. Age and family history are also a risk factor. A man's risk of a heart attack increases after the age of 45 and a woman's risk increases after menopause, around 55 years of age. If a member of your family has heart disease or has had a heart attack, it also increases your risk for a heart attack.
