Women’s hearts beat differently!
Why Heart Disease Is Different in Women Than in Men
Heart disease is often considered a “man’s problem” — but this myth is not only medically incorrect, it is also dangerous. In reality, cardiovascular diseases are the leading cause of death among women. Because they often develop and present differently in women than in men, they are frequently recognized too late or misdiagnosed.

Women Experience Different Symptoms — and They Are Often Overlooked
Perhaps the most important misunderstanding concerns the symptoms of a heart attack or coronary heart disease. While men typically experience strong chest pain and a feeling of “crushing pressure,” many women show different or additional warning signs.
According to a large U.S. study (McSweeney, J. C. et al., Women’s Early Warning Symptoms of Acute Myocardial Infarction, Circulation), women commonly report the following symptoms before a heart attack:
- Shortness of breath
- Weakness or general exhaustion
- Unusual fatigue
- Sleep disturbances
During acute events, 43% of women did not experience the pronounced chest pain that is classically associated with heart attacks in men.
The Mayo Clinic also confirms that women frequently report additional symptoms such as pain in the neck, back, jaw, or upper abdomen, as well as nausea, dizziness, or even digestive problems — symptoms that are not immediately associated with a cardiac event.
These “nonspecific” symptoms often lead women to underestimate their own complaints or cause medical professionals to initially suspect harmless causes such as stress, stomach problems, or fatigue.

Heart Disease Often Develops Differently in Women
Another reason heart disease differs between women and men lies in how the disease develops:
- Women typically develop heart disease about a decade later than men. One reason is the protective effect of estrogen before menopause, which slows the development of arterial plaque buildup (atherosclerosis).
- However, after menopause the risk rises sharply. Women also have lower survival rates after a heart attack, partly because symptoms are often recognized later.
Additionally, some women do not show clear blockages in the major coronary arteries. Instead, they may experience dysfunction in the smaller blood vessels (microcirculation). This so-called “small vessel disease” may not appear clearly on standard angiography, which can delay or complicate diagnosis.

Biological Differences Influence Symptoms and Diagnosis
Women’s hearts and blood vessels differ from men’s in several biological ways:
- Heart size and anatomy: The female heart is on average smaller, and the blood vessels are more finely branched, which can influence both symptoms and how well conditions are detected in diagnostic tests.
- Changes after menopause: Declining estrogen levels promote inflammatory processes and the development of cardiovascular disease.
- Different warning signs: Studies show that women often experience more numerous and varied symptoms before a cardiac event than men, making interpretation more difficult for medical professionals.
-
Perception and Treatment — Social and Medical Factors
Awareness and medical training still play a major role:
- Many women themselves still consider heart disease a “male problem.” As a result, the risk is underestimated and warning signs are taken less seriously.
- Historically, the medical community has also understood heart disease in women less well, partly because women were underrepresented in cardiovascular studies for a long time.
These factors contribute to the fact that women, on average, arrive at the emergency department later than men, delaying treatment and worsening outcomes.
A new study conducted with MEDIACC shows that artificial intelligence can help break this invisibility.[5]
Key findings:
- Superior to standard tools: While conventional scores like the CVRF score simply add up risk factors, the CSG Index “sees” patterns hidden within the data.
- Especially better in women: In the study, the CSG Index performed significantly better for women.
- Making the invisible visible: Particularly remarkable was its ability to detect early disease in symptom-free women. This means that even without symptoms, heart weakness or vascular alterations could be predicted.
This is especially the case when a conventional ECG appears normal. Cardisiography showed superior accuracy in detecting cardiovascular risk, particularly in asymptomatic women.
What is included in a Cardisiography report:
- Ischemia Index (CSG Ischemia Index / “P”)
- Structural Heart Disease Index (CSG-SHD / “S”)
- Arrhythmia Index (A)
Additionally: selected VCG parameters (QRS-T angle, QRS duration, T-wave metrics), a 12-lead ECG view plus extended leads: extended left-sided leads V7–V9 and right-sided leads Vr3–Vr6 (ESC guideline recommendation from 2023), and vector loops.
More advanced technologies in this field, such as CT or MRI, are too complex and too expensive to use prophylactically. Cardisiography was specifically developed as a decision-support tool for the early diagnostic phase, to detect heart diseases that do not appear in conventional ECG examinations.
Cardisiographs comply with the standards and regulations according to EN 55032:2015 Class B, EN55024:2010+A1:2015, 47 CFR Part 15.

What Women (and Everyone) Should Know
Recognizing heart disease: A heart attack does not always mean severe chest pain. In women, symptoms such as fatigue, shortness of breath, nausea, or back pain may be more prominent.
Act quickly: Whether symptoms are typical or atypical, suspected heart disease requires immediate medical attention.
Address risk factors: High blood pressure, diabetes, smoking, obesity, and stress significantly increase cardiovascular risk in women.
