What are the prognostic implications of microvascular angina in women with myocardial ischemia?
Studies have shown that in women with myocardial ischemia and no obstructive coronary artery disease, the prognosis is worse than those with obstructive coronary artery disease. A 2004 study published in the journal Circulation found that women with myocardial ischemia and no obstructive coronary artery disease had a higher risk of death, recurrent ischemic events, and heart failure compared to women with obstructive coronary artery disease. Furthermore, the presence of microvascular angina further increased the risk of adverse cardiovascular events. Therefore, microvascular angina in women with myocardial ischemia is associated with a worse prognosis.
