More women die of cardiovascular disease than men; in women, cardiovascular mortality is 1.5 times greater than cancer mortality. The pathophysiology of cardiovascular disease has female-specific aspects such as fragile coronary arteries and microvascular ischaemia. Women with acute coronary syndromes are more likely to present with atypical symptoms such as dyspnoea, nausea or fatigue. With regard to diagnostic tests in women, exercise ECG can be difficult to interpret and a normal coronary angiogram does not exclude coronary heart disease. Myocardial perfusion scintigraphy may be considered for high-risk women who are clinically suspected of having coronary heart disease and have a normal or inconclusive exercise ECG and angiogram. Women are less likely to be treated according to guidelines than men, and their prognosis after a myocardial infarction or a coronary intervention is worse. Female-specific aspects such as gestational hypertension and diabetes allow for early detection and treatment of women at risk for cardiovascular disease.
