Women generally have higher heart rates and smaller hearts and arteries than men. This means that when it comes to heart disease, plaque builds differently within women’s blood vessels.
Female hormones can also make arteries smaller, causing them to be more prone to blood clots or blockages and more difficult to repair.
Women can show different symptoms of a heart attack. For both men and women, the most common sign of a heart attack is chest pain or discomfort, but women can experience a heart attack without chest symptoms. They may experience shortness of breath, dizziness, lightheadedness or fainting, upper back pressure or extreme fatigue. Because symptoms in women can be less specific, they can be harder to recognize as danger signs.
Women may also experience different mental and neurological symptoms when they experience a blood vessel related injury to the brain such as a TIA (mini-stroke) – a problem in the blood vessels of the brain that causes a temporary decrease in blood flow to a certain brain region. Because women and men’s brains and blood vessels are slightly different in form and function, stroke and TIA symptoms can vary widely in women compared to men, depending on the part of the brain that is affected.
According to the Heart and Stroke Foundation, the following are true, when comparing cardiovascular health between women and men:
Explaining why these differences exist and what can be done to address them requires more research.
Some risk factors are a red flag for women. While men and women share most of the same risk factors, some of them, such as smoking, diabetes, high blood pressure, and a family history of heart disease or stroke, may pose an even greater threat for women than for men. It’s also believed that estrogen protects against heart complications, but once estrogen levels drop during menopause, the risk of heart disease within women rises. And as women age they are more likely to have other conditions, such as diabetes, that can further increase risk and complicate a diagnosis.
Knowing your risk factors is the first step in prevention. For example, you can reduce your risk by having regular medical checkups and focusing on treatable risk factors like:
It’s also important to be aware of non-treatable risk factors like age, gender, race, and family history as they will play a role in determining an individual patient’s risk for heart disease and stroke. If you are unsure, speak to your health care practitioner about your risk factors, and possible lifestyle changes and regular screening options that can help lower your risk.
An exercise stress test and myocardial perfusion imaging are medical imaging tests that can evaluate heart function. For a detailed look at coronary arteries, your doctor might also order computed tomography imaging. Magnetic resonance imaging can be requested to look at the blood vessels in the brain and for signs of a stroke.
