A Woman’s Heart Attack Causes & Symptoms may Differ from a Man’s

Statement Highlights

  • Women frequently have different underlying causes of heart attacks than men, such as the types of plaque build-up.
  • Compared to men, women tend to be undertreated and are less likely to participate in cardiac rehab after a heart attack.
  • Risk factors (such as high blood pressure and diabetes) increase heart attack risk in women more severely than in men.

A woman’s heart attack may have different underlying causes, symptoms and outcomes compared to men, according to a scientific statement published in the American Heart Association’s journal Circulation.

The statement is the first scientific statement from the American Heart Association on heart attacks in women. It notes that there have been dramatic declines in cardiovascular deaths among women due to improved treatment and prevention of heart disease as well as increased public awareness.

“Despite stunning improvements in cardiovascular deaths over the last decade, women still fare worse than men and heart disease in women remains underdiagnosed, and undertreated, especially among African-American women,” said writing group chair Laxmi Mehta, M.D., a noninvasive cardiologist and Director of the Women’s Cardiovascular Health Program at The Ohio State University.

Causes:
Heart attacks caused by blockages in the main arteries leading to the heart can occur in both men and women. However, the way the blockages form a blood clot may differ. Compared to men, women can have less severe blockages that do not require any stents; yet the heart’s coronary artery blood vessels are damaged which results in decreased blood flow to the heart muscle. The result is the same – when blood flow to the heart is decreased for any reason, a heart attack can occur. If doctors do not correctly diagnose the underlying cause of a woman’s heart attack, they may not be prescribing the right type of treatments after the heart attack. Medical therapies are similar regardless of the cause of the heart attack or the severity of the blockages. However, women are undertreated compared to men despite proven benefits of these medications.

Treatment:
Women face greater complications from attempts to restore blood flow because their blood vessels tend to be smaller, they are older and have increased rates of risk factors, such as diabetes and high blood pressure.The recommended guidelines for medications medications are consistently underutilised in women, leading to worse outcomes. Also, cardiac rehabilitation is prescribed less frequently for women and even when it is prescribed, women are less likely to participate in it or complete it.

Symptoms:
While the most common heart attack symptom is chest pain or discomfort for both sexes, women are more likely to have atypical symptoms such as shortness of breath, nausea or vomiting, and back or jaw pain.

Risk factors:
Risk factors for heart attacks also differ in degree of risk in men compared to women. For example, high blood pressure is more strongly associated with heart attacks in women and if a young woman has diabetes, her risk for heart disease is 4 to 5 times higher than that of a young man.
