Background

Primarypercutaneous coronary intervention (PCI) remains recommended reperfusiontherapy for patients with acute ST-elevation myocardial infarction. This studyaimed to evaluate the short-term major adverse cardiac events (MACE) and theirdeterminants among patients who underwent primary PCI at a tertiary carecardiac center of Karachi, Pakistan. 

Methods

Acohort of patients who underwent primary PCI were followed for the MACE.Multivariable Cox-regression analysis was performed with backward conditionalvariable selection and hazard ratio (HR) along with 95% confidence interval(CI) were obtained.

Results

Atotal of 1150 patients were included, of which follow-up was successful in95.8% (1102) and mean follow-up duration was 5.97±2.32 months. MACE wereobserved in 201 (19.1%) patients with 14.2% (157) all-cause mortality, 5.4% (60)cardiac mortality, 0.7% (8) stroke, 3.6% (40) re-hospitalization due to heartfailure, and 6.1% (67) myocardial infarction requiring revascularization.Independent predictors of short-term MACE were found to be admission glucose≥200 mg/dl (1.66 [1.25-2.21]), serum creatinine ≥1.5 mg/dl (1.52 [1.02-2.27]), intubation (2.81[1.98-4.00]), history of PCI (2.06 [1.45-2.93]), history of cerebrovascular accident (2.64 [1.34-5.2]), left ventricular end-diastolic pressure ≥20 mmHg (1.81 [1.3-2.51]), triple vessel diseases (1.43 [1.08-1.9]), culprit left main or proximal left anterior descending artery (1.77 [1.32-2.35]), pre-ballooning (2.14[1.2-3.82]), and thrombus grade≥4 (2.21 [1.51-3.24]).

Conclusion

Asignificant number of individuals undergone primary PCI are still vulnerable tosubsequent short-term MACE, hence, systematic follow-up and early riskstratification should be considered as an integral part of STEMI managementprotocol specially for patients with high-risk features as highlighted herein.
