Cardiogenic shock due to cardiac free-wall rupture or tamponade after acute myocardial infarction: a report from the SHOCK Trial Registry

摘要: OBJECTIVES We sought to compare the characteristics and outcomes of patients with acute myocardial infarction (MI) cardiogenic shock (CS) caused by rupture ventricular free wall or tamponade versus from other causes. BACKGROUND Free-wall is a recognized cause mortality in MI. Some these present subacutely, which provides an opportunity for intervention. Recognition factors that distinguish them overall cohort would be beneficial. METHODS The international SHOCK Trial Registry enrolled concurrently randomized Trial. Thirty-six centers consecutively all suspected CS after MI, regardless trial eligibility. RESULTS Of 1,048 studied, 28 (2.7%) had free-wall tamponade. These less pulmonary edema, diabetes, prior congestive heart failure (all p < 0.05). They more often new Q waves two leads (51.9% vs. 31.5%, 0.04), but MI location time onset did not differ. tamponade, 75% pericardial effusions. No hemodynamic identified rupture/tamponade. Most rupture/tamponade surgery and/or pericardiocentesis (27/28); their in-hospital survival rate was identical group (39.3%). Women older tended survive intervention often. CONCLUSIONS may as similar cohort. AU should have echocardiography order detect subacute initiate appropriate interventions. (J Am Coll Cardiol 2000;36:1117-22) (C) 2000 American College Cardiology.
