Background
Resolution of ST elevation (STE) is the hallmark of successful thrombolysis for ST- Elevation Myocardial Infarction (STEMI). The effect of persistent STE on in-hospital outcomes following primary percutaneous coronary intervention (PPCI) is not well established.
Methods
In this single-center retrospective cohort analysis, all patients admitted between Jan 1,2016 and Sep 30,2018 with a diagnosis of STEMI who underwent PPCI were included. Complete resolution was defined as >70% decrease in the STE sum on the first ECG following PPCI. Partial resolution denoted a 30-70% decrease, and persistent STE denoted <30% decrease, or any increase in the STE sum. The study population was divided into two groups: (1) resolved STE incorporating complete and partial resolution; (2) persistent STE incorporating persistent and increased STE. Using multivariate logistic regression, we compared the rates of in-hospital mortality, cardiogenic shock, ICU admission, clinical heart failure, and readmission for a cardiac reason and heart failure between the study groups.
Results
We included 1,250 patients in the analysis. Most of the patients were male (96 %) with a mean age of 52±10 years. More than three-quarters were Asian. Compared with patients with resolved STE, patients with persistent STE had higher risk of clinical heart failure (24% vs 12%, adjusted odds ratio 1.7 [95% Confidence Interval 1.2-2.5], p-value 0.003), cardiogenic shock (12.1% vs 5.3%, aOR 2.7 [95% CI 1.73-4.24], p-value <0.001), in-hospital mortality (5.1% vs 2.1%, aOR 4.8 [95% CI 2.35-9.88], p-value < 0.001), and readmission for heart failure (6.9% vs. 1.6%, aOR 3.9[95% CI 1.95-7.82], p-value <0.001).
Conclusion
Persistent STE following PPCI is a quick clinical indicator of in-hospital adverse outcomes as well as readmission. Future studies may explore interventions, such as early intensive medical therapy, that can improve outcomes in this population.
