Heart disease is the leading cause of death for both men and women in the United States. But the way it affects women is often very different—and far less understood. Many people still think of heart attacks as something that mostly happens to men. This misunderstanding can delay care and increase risk for women. The truth is, women’s bodies are different, and their symptoms, risk factors, and responses to treatment don’t always match what we’ve traditionally been taught about heart disease.
Let’s start with anatomy. Women tend to have smaller hearts and narrower blood vessels compared to men. This makes a big difference. Most heart tests were designed based on male anatomy, especially tests like angiograms, which use dye and X-rays to check for blockages. Smaller blood vessels don’t always show up well on these tests, so a woman with narrowing or disease in those small vessels might be told everything looks normal—even when it’s not. Women are also more likely than men to develop microvascular disease, which affects the tiny blood vessels of the heart. These don’t always cause the “classic” signs of a heart attack but can still lead to real damage.
Many women also have different risk factors. Conditions linked to women’s reproductive health—like endometriosis, polycystic ovary syndrome (PCOS), and early menopause—can all increase the chance of developing heart disease. Pregnancy complications such as gestational diabetes and preeclampsia are red flags, too. These events might seem unrelated to the heart, but they can signal deeper problems with blood vessels and how the body handles stress. A woman who has had one of these issues during pregnancy should talk to her doctor about her heart health, even if she feels fine.
Another big difference is how a heart attack feels. For men, it’s often described as intense chest pain or pressure, like an elephant sitting on the chest. But women might not feel that at all. In fact, many women don’t feel any chest pain. Instead, they may feel short of breath, nauseous, dizzy, extremely tired, or like they have the flu. Some describe back pain, jaw pain, or pressure in the upper stomach. These symptoms can be brushed off as stress, anxiety, or a stomach bug—and that delay can be dangerous.
Even worse, about two-thirds of women who die suddenly from heart disease had no warning symptoms at all. That’s why it’s so important to pay attention to your body and push for testing if something doesn’t feel right. Some women are diagnosed with conditions that mimic heart attacks, such as coronary spasm (a temporary tightening of the artery), spontaneous coronary artery dissection (a tear in the blood vessel wall), or Takotsubo cardiomyopathy, often called “broken heart syndrome.” These can be triggered by emotional stress and may not always show up on standard tests—but they’re very real and can be life-threatening.
When it comes to medications, women again face unequal treatment. Studies show women are less likely than men to be prescribed life-saving drugs after a heart attack. These include aspirin, cholesterol-lowering statins, and blood pressure medications. The reasons aren’t completely clear, but gender bias in medicine may play a role. Doctors may not see women as being “at risk,” even when the evidence says otherwise.
Diagnostic tests may also need to be adjusted. One of the main tests used to confirm a heart attack is the troponin blood test. Troponin is a protein released when the heart muscle is damaged. But here’s the issue: the standard test uses the cutoff values from men. Women may have lower levels of troponin even during a heart attack, which means they could be misdiagnosed or sent home. New guidelines suggest using sex-specific cutoffs, but not all hospitals have made that change yet.
Even when women are diagnosed properly, they may not receive the same treatments as men. For example, coronary artery bypass surgery—an operation to fix blocked arteries—has higher risks and death rates in women. That doesn’t mean women shouldn’t have surgery when needed, but it highlights the importance of tailoring care. Some women may benefit more from medications and lifestyle changes rather than invasive procedures, depending on their overall health and the type of heart disease they have.
Then there’s the issue of medical bias. Many women report that their concerns are dismissed or not taken seriously when they describe symptoms. In emergency rooms, women with chest pain wait longer than men to be evaluated. Some doctors may be less familiar with the risk factors or may misread symptoms as anxiety or panic attacks. That’s why it’s important for women to advocate for themselves—and for providers to listen carefully and look at the whole picture, not just textbook symptoms.
So what can women do? First, know your numbers. Blood pressure, cholesterol, blood sugar, and body weight all matter. Keep track of them and work with your doctor to keep them in a healthy range. Second, take pregnancy complications seriously—these aren’t just short-term issues but could be early signs of future heart problems. Third, know the symptoms of a heart attack in women, and don’t ignore unusual fatigue, nausea, or shortness of breath.
And finally, speak up. If something feels wrong, get it checked. Ask your provider whether tests and treatments are tailored to women. The more we understand about how heart disease affects women, the more lives we can save. Women’s hearts are not just smaller versions of men’s hearts—they deserve their own spotlight, their own research, and their own personalized care.
