Objectives. We aimed to analyse data from our high-volume interventional centre (>1000 primary percutaneous coronary
interventions (PCI) per year) searching for predictors of in-hospital mortality in acute myocardial infarction (MI) patients.
Moreover, we looked for realistic strategies and interventions for lowering in-hospital mortality under the “5 percent threshold.”
Background. Although interventional and medical treatment options are constantly expanding, recent studies reported a residual
in-hospital mortality ranging between 5 and 10 percent after primary PCI. Current data sustain that mortality after ST-elevation
MI will soon reach a point when cannot be reduced any further. Methods. In this retrospective observational single-centre cohort
study, we investigated two-year data from a primary PCI registry including 2035 consecutive patients. Uni- and multivariate
analysis were performed to identify independent predictors for in-hospital mortality. Results. All variables correlated with
mortality in univariate analysis were introduced in a stepwise multivariate linear regression model. Female gender, hypertension,
depressed left ventricular ejection fraction, history of MI, multivessel disease, culprit left main stenosis, and cardiogenic shock
proved to be independent predictors of in-hospital mortality. e model was validated for sensitivity and specificity using receiver
operating characteristic curve. For our model, variables can predict in-hospital mortality with a specificity of 96.60% and a
sensitivity of 84.68% (p < 0.0001, AUC 0.93, 95% CI 0.922–0.944). Conclusions. Our analysis identified a predictive model for in-
hospital mortality. e majority of deaths were due to cardiogenic shock. We suggested that in order to lower mortality under 5
percent, focus should be on creating a cardiogenic shock system based on the US experience. A shock hub-centre, together with
specific transfer algorithms, mobile interventional teams, ventricular assist devices, and surgical hybrid procedures seem to be the
next step toward a better management of ST-elevation MI patients and subsequently lower death rates.
1. Introduction
Myocardial infarction (MI) remains one of the leading causes of
global cardiovascular burden [1]. Even if numerous efforts have
been made to increase awareness, prevention, and management
of acute MI, it still has a high incidence—ST-elevation
myocardial infarction (STEMI) accounting for high mortality
and morbidity rates [2]. Since 2008, when “Stent for Life” ini-
tiative expanded throughout all Europe (including Eastern
countries), death rates in STEMI decreased to a plateau [3].
Although interventional and medical treatment options
are constantly expanding, recent studies reported a residual
