Abstract:
Mechanical complications of an acute coronary syndrome can lead to hemodynamic instability out of proportion to the degree of left ventricular dysfunction. We present the case of a patient with cardiogenic shock secondary to severe mitral regurgitation in the setting of an acutely occluded obtuse marginal artery. Echocardiography and pathologic findings revealed an uncommon cause of anterolateral papillary muscle rupture. Using the unique features of this case, we present a clinical self-assessment exercise highlighting the challenges involved in the management of this type of patient.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
