Abstract

Background

Microaxial circulatory support devices have been used to support patients treated with percutaneous coronary intervention (PCI) for acute myocardial infarction complicated by cardiogenic shock (AMICS). The purpose of this systematic review and meta-analysis was to pool and analyze the existing evidence on the baseline characteristics, periprocedural data, and outcomes of microaxial support before and after PCI in AMICS.

Methods

An electronic database search was performed to identify all cohort studies on Impella and PCI for cardiogenic shock in the English language. A total of five articles comprising 543 patients were included. These patients received microaxial support either before (pre-PCI) or after (post-PCI) undergoing PCI. Comparative analyses were done between both groups.

Results

The mean patient age was 66 years [95% Confidence Interval (58–74)], and 22% (89/396) of patients were female. ST-elevation myocardial infarctions (MI) comprised 64% (44–80) of MIs and 50% (44–56) of MIs involved the left anterior descending artery. The mean number of diseased vessels was 2.21 (1.62–2.80). The mean left ventricular ejection fraction was 31% (23.4–38.6). The mean arterial pressure was 66.3 mm Hg (54.1–78.5). Mean serum lactate [6.1 mmol/L (3.3–8.9)] and serum creatinine [1.4 mg/dl (1.0–1.7)] were similar between groups. 30-day mortality was lower in the pre-PCI group [41% (34%–49%)] compared to the post-PCI group [61% (42%–77%), p < 0.01]. Pooled Kaplan–Meier analysis showed better early survival in the pre-PCI group (p < 0.001).

Conclusion

Patients presenting with AMICS were similar at baseline in both pre-PCI and post-PCI groups. Nevertheless, pre-PCI group showed better early survival compared to post-PCI group.
