Effects of intra-aortic balloon pump on in-hospital outcomes and 1-year mortality in patients with acute myocardial infarction complicated by cardiogenic shock.

ABSTRACT:

Background

The role of intra-aortic balloon counterpulsation (IABP) in cardiogenic shock complicating acute myocardial infarction (AMI) is still a subject of intense debate. In this study, we aim to investigate the effect of IABP on the clinical outcomes of patients with AMI complicated by cardiogenic shock undergoing percutaneous coronary intervention (PCI).

Methods

From the Medical Information Mart for Intensive Care (MIMIC)-IV 2.2, 6017 AMI patients were subtracted, and 250 patients with AMI complicated by cardiogenic shock undergoing PCI were analyzed. In-hospital outcomes (death, 24-hour urine volumes, length of ICU stays, and length of hospital stays) and 1-year mortality were compared between IABP and control during the hospital course and 12-month follow-up.

Results

An IABP was implanted in 30.8% (77/250) of patients with infarct-related cardiogenic shock undergoing PCI. IABP patients had higher levels of Troponin T (3.94 [0.73-11.85] ng/ml vs. 1.99 [0.55-5.75] ng/ml, p-value = 0.02). IABP patients have a longer length of ICU and hospital stays (124 [63-212] hours vs. 83 [43-163] hours, p-value = 0.005; 250 [128-435] hours vs. 170 [86-294] hours, p-value = 0.009). IABP use was not associated with lower in-hospital mortality (33.8% vs. 33.0%, p-value = 0.90) and increased 24-hour urine volumes (2100 [1455-3208] ml vs. 1915 [1110-2815] ml, p-value = 0.25). In addition, 1-year mortality was not different between the IABP and the control group (48.1% vs. 48.0%; hazard ratio 1.04, 95% CI 0.70-1.54, p-value = 0.851).

Conclusion

IABP may be associated with longer ICU and hospital stays but not better short-and long-term clinical prognosis.

N Engl J Med 2012, 367:1287-1296.In the current international guidelines, intra-aortic balloon pump (IABP) counterpulsation is considered a class I treatment for acute myocardial infarction complicated by cardiogenic shock. However, evidence is based mainly on registry data, and there is a paucity of randomized clinical trials.To test the hypothesis that IABP counterpulsation, as compared with the best available medical therapy alone, results in a reduction in mortality among patients with acute myocardial infarction complicated by cardiogenic shock for whom early revascularization is planned.Randomized, prospective, open-label, multicenter trial.Thirty-seven centers in Germany.All adults had acute myocardial infarction complicated by cardiogenic shock and were expected to undergo early revascularization (by means of percutaneous coronary intervention or bypass surgery).After enrollment, 600 patients were randomly assigned to intra-aortic balloon counterpulsation (IABP group, 301 patients) or no IABP counterpulsation (control group, 299 patients).The primary efficacy endpoint is 30-day all-cause mortality.At 30 days, 119 patients in the IABP group (39.7%) and 123 patients in the control group (41.3%) had died (relative risk with IABP, 0.96; 95% confidence interval, 0.79 to 1.17; P=0.69). There were no significant differences in secondary endpoints or in process-of-care measures, including the time to hemodynamic stabilization, the length of stay in the intensive care unit, serum lactate levels, the dose and duration of catecholamine therapy, and renal function.The use of IABP counterpulsation did not significantly reduce 30-day mortality in patients with acute myocardial infarction complicated by cardiogenic shock for whom an early revascularization strategy was planned.

Project description:Background Clinical outcomes of acute myocardial infarction complicated by cardiogenic shock remain poor with high in-hospital mortality. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been widely used for patients with acute myocardial infarction complicated by cardiogenic shock refractory to conservative therapy, which is likely fatal without mechanical circulatory support. However, whether additional intra-aortic balloon pumping (IABP) use during VA-ECMO support improves clinical outcomes remains controversial. This study sought to investigate prognostic impact of the combined VA-ECMO plus IABP treatment compared with VA-ECMO alone. Methods and Results From the nationwide Japanese administrative case-mix Diagnostic Procedure Combination (DPC), the JROAD (Japanese Registry of All Cardiac and Vascular Diseases)-DPC, we identified 3815 patients with acute myocardial infarction complicated by cardiogenic shock who underwent primary percutaneous coronary intervention and managed with VA-ECMO. Of these, 2964 patients (77.7%) were managed with IABP (VA-ECMO plus IABP), whereas 851 (22.3%) were managed without IABP (VA-ECMO alone). We compared in-hospital, 7-day, and 30-day mortality between the VA-ECMO plus IABP versus the VA-ECMO alone support. Patients managed with VA-ECMO plus IABP demonstrated significantly lower in-hospital, 7-day, and 30-day mortality than those managed with VA-ECMO alone (adjusted odds ratios [95% CI] of 0.47 [95% CI, 0.38-0.59], 0.41 [95% CI, 0.33-0.51], and 0.30 [95% CI, 0.25-0.37], respectively). The findings were consistent in the propensity matching and inverse probability of treatment-weighting models. Conclusions This large-scale, nationwide study demonstrated that the combination of VA-ECMO plus IABP support was associated with significantly lower mortality compared with VA-ECMO support alone in patients presenting with acute myocardial infarction complicated by cardiogenic shock who underwent primary percutaneous coronary intervention.
