Which gender has the higher risk of a heart attack?

At first, we may perceive that a woman and man’s heart are exactly the same, except for size differences (obviously!). However, medically, there are some significant differences that we should be aware of.

Differences

A women’s heart is usually much smaller, including some of the interior chambers of the heart. The walls that divide such chambers are also a lot thinner. Whilst a woman’s heart pumps faster than her male counterparts, it ejects about 10% less blood with each squeeze.

When a woman is stressed, her pulse rate rises and her heart pumps more blood. However, when a man is stressed, the arteries of his heart constrict, raising his blood pressure.

Why do these differences matter? They matter because gender plays a role in the symptoms, treatments and outcomes of coronary artery disease (CAD).

Women have risk factors that men don’t have

There are some diseases that only affect women such as:

  • Endometriosis
  • Polycystic ovary disease
  • Diabetes & high blood pressure developing during pregnancy

All of which contribute to the risk of coronary artery disease which is the leading cause of a heart attack. Endometriosis has been found to raise the risk of developing CAD by 400% in women under the age of 40.

Women share traditional risk factors with men:

  • High blood pressure
  • High sugar levels
  • High cholesterol levels
  • Smoking
  • Obesity
  • Family history of heart disease

Both men and women are impacted by the above. A female can be impacted more so by family history of heart disease, particularly when a father or brother diagnosed with CAD before age 55, or a mother or sister had been diagnosed before age 65.
