Abstract

Background: Patients over 75 years old presenting with ST elevated myocardial infarction in cardiogenic shock portend a very high risk of mortality. Prognostic predictors for these patients undergoing contemporary primary angioplasty are not well established. Methods: This is a subanalysis of the nationwide database of primary angioplasty in the elderly (ESTROFA MI+75) with 3,576 patients included in 31 centers. Characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed. Results: A total of 332 patients were included in the analysis (9.3%), age 81+/‐4 years, 39.5% women, 35.8% diabetics, 49% with anterior infarction, ejection fraction 39 +/‐14% and 34% with > 6 hours since pain onset. The procedure was done through radial access in 27%, with bivalirudin in 7%, abciximab in 32%, thrombus aspiration in 54%, drug‐eluting stent in 21% and intra‐aortic balloon in 45%. Baseline independent predictors for mortality were anterior myocardial infarction (HR 2.8, 95% CI 1.4‐6; p=0.005), LVEF < 40% (HR 2.3, 95% CI 1.14‐4.5; p=0.018) and time from symptoms onset to PCI > 6 hours (HR 3.2, 95% CI 1.6‐7.5; p=0.001). A score was designed including these 3 factors (Score "6‐ANT‐40"), assigning 1 point for meeting each. Survival at 12 months was 54.5% for patients with Score 0, 32.3% for Score 1, 27.4% for Score 2 and 17% for Score 3 (p=0.004). Conclusions: In patients over 75 years referred for primary PCI with cardiogenic shock, baseline independent predictors for mortality were a presentation with more than 6 hours after symptoms onset, anterior myocardial infarction and LVEF < 40%. A significantly different risk of mortality was observed for a scoring based on these factors.
