CARDIOVASCULAR RISK FACTOR A cardiovascular is a conditionthatisassociatedwithanincreasedriskofdevelopingcardiovasculardisease.condition that is associated with an increased risk of developing cardiovascular disease. The risk factors may be classified as those that cannot be changed and those that can be changed, controlled or treated.

A. Risk Factors That Cannot Be Changed

  1. Family history. If a first-degree blood relative has had coronary heart disease or stroke before the age of 55 years (for a male relative) or 65 years (for female relative), %%you might be at risk of contracting the same disease.%%
  2. Age. Through the years the %%heart undergoes subtle physiologic changes even in the absence of disease.%% The muscle of the aged heart may relax less completely between beats, and %%as a result, the pumping chambers become stiffer and may work less efficiently.%%
  3. Gender. Men are at a greater risk of heart disease than pre-menopausal women. Once past menopause, a woman’s risk is similar to a man’s. The risk of stroke, however, is the same for both men and women.

Risk Factors That Can Be Controlled, Changed, or Treated

  1. Smoking
  2. Drinking alcohol
  3. Illegal drugs
  4. Hypertension
  5. High Cholesterol
  6. Physical inactivity
