Heart Disease in Women
Heart disease is the leading cause of death in women, yet it is often underdiagnosed due to "silent" symptoms or presentations that differ from those in men.
Understanding Heart Disease
Heart disease, or cardiovascular disease, is a general term for heart and blood vessel problems. Coronary artery disease is the most common type, occurring when plaque narrows or blocks blood flow to the heart muscle, potentially leading to angina, heart attacks, heart failure, and arrhythmia.
Why Diagnosis Can Be Delayed
Women are often diagnosed later than men because:
- They are more likely to have "silent" heart disease without symptoms.
- Symptoms in women may differ from the traditional symptoms seen in men.
- Women are more likely to experience types of heart disease that are harder to diagnose.
Types of Heart Disease Affecting Women
While coronary artery disease is most common, women are more frequently affected by:
- Coronary microvascular disease: Spasms in the smallest arteries of the heart that pinch off blood flow, often during rest or routine activity.
- Broken heart syndrome: Stress-induced chest pain caused by powerful emotions like grief or anger, which can mimic a heart attack.
- Variant angina: A rare type of chest pain caused by spasms in heart arteries, typically occurring during sleep.
Risk Factors
Risk increases with age, particularly after menopause, as protective estrogen levels drop. Other risk factors include:
- Family history of heart disease.
- Pregnancy complications (e.g., high blood pressure, gestational diabetes).
- Use of hormonal birth control.
- Conditions such as endometriosis, polycystic ovary syndrome, autoimmune diseases, metabolic syndrome, and mental health issues.
- Lifestyle factors: smoking, obesity, lack of physical activity, and poor diet.
- Medical conditions: diabetes, high blood pressure, and low HDL cholesterol.
Symptoms in Women
Women may experience chest pain, but they are also more likely to report:
- Pain in the neck, jaw, throat, upper belly, or back.
- Nausea or vomiting.
- Unusual fatigue.
- Shortness of breath during physical activity.
During a heart attack, women may feel pressure or tightness in the chest, dizziness, indigestion, or stomach pain. Symptoms may be mild, start slowly, or come and go.
