Why the study?
To describe cases demonstrating the importance of cardiac catheterization in patients who experience vasospastic angina during hospitalization for non-cardiac complaints.
Case Report (n=2)
Cardiac catheterization is essential in patients presenting with vasospastic angina to identify or rule out underlying obstructive coronary artery disease, which significantly alters management and prognosis.
Significant CAD may coexist with vasospastic angina; leaves open whether catheterization is warranted in all cases.
Prinzmetal angina, also known as vasospastic or variant angina, is defined as an intermittent focal coronary artery spasm often associated with an atherosclerotic lesion near the site of spasm. It is caused by a focal or diffuse spasm of the smooth layer of the arterial wall of an epicardial coronary artery. Acute infarctions or malignant arrhythmias may develop during spasm-induced ischemia. Evaluation includes observation of echocardiogram (EKG) for transient ST elevations during discomfort; diagnosis is confirmed with coronary angiography using provocative testing. We describe two cases of patients who presented for non-cardiac complaints, but had episodes of vasospastic angina during their hospitalization. Both underwent cardiac catheterization with differing results, demonstrating the importance of catheterization in patients who experience vasospastic angina.
