Angiographic findings and clinical correlates in patients with cardiogenic shock complicating acute myocardial infarction: a report from the SHOCK Trial Registry

摘要: OBJECTIVES We sought to delineate the angiographic findings, clinical correlates and in-hospital outcomes in patients with cardiogenic shock (CS) complicating acute myocardial infarction. BACKGROUND Patients CS infarction carry a grave prognosis. Detailed findings large, prospectively identified cohort of are currently lacking. METHODS compared characteristics, 717 selected undergo angiography 442 not selected, overall by etiology: left or right ventricular failure versus mechanical complications. RESULTS who underwent had lower baseline risk better hemodynamic profile than those did not. Overall, 15.5% significant main lesions on angiography, 53.4% three-vessel disease, higher rates both for failure, Among significantly mortality complications (45.2% vs. 57.0%; p = 0.021). Importantly, also correlated disease severity: 35.0% no single-vessel 50.8% disease. Furthermore, was associated culprit lesion location (78.6% lesion, 69.7% saphenous vein graft lesions, 42.4% circumflex 42.3% anterior descending 37.4% coronary artery lesions), Thrombolysis In Myocardial Infarction (TIMI) flow grade (46.5% TIMI 0/1, 49.4% 2 26% 3). CONCLUSIONS study SHOCK Trial Registry more benign cardiac profile, favorable whom angiograms were obtained. caused severe atherosclerosis, different distribution vessel involvement but mortality, Overall survival extent obstructions, grade.
