Factors associated with temporary pacing insertion in patients with inferior ST-segment elevation myocardial infarction

Abstract

Background High-degree atrioventricular block (HAVB) is a prognostic factor for survival in patients with inferior ST-segment elevation myocardial infarction (STEMI). However, there is little information about factors associated with temporary pacing (TP). The aim of this study was to find factors associated with TP in patients with inferior STEMI. Methods We included 232 inferior STEMI patients, and divided those into the TP group (n = 46) and the non-TP group (n = 186). Factors associated with TP were retrospectively investigated using multivariate logistic regression model. Results The incidence of right ventricular (RV) infarction was significantly higher in the TP group (19.6%) than in the non-TP group (7.5%) (p = 0.024), but the incidence of in-hospital death was similar between the 2 groups (4.3% vs. 4.8%, p = 1.000). Long-term major adverse cardiovascular events (MACE), which were defined as a composite of all-cause death, non-fatal myocardial infarction (MI), target vessel revascularization (TVR) and readmission for heart failure, were not different between the 2 groups (p = 0.100). In the multivariate logistic regression analysis, statin at admission [odds ratio (OR) 0.230, 95% confidence interval (CI) 0.062–0.860, p = 0.029], HAVB at admission (OR 9.950, 95% CI 4.099–24.152, p<0.001), and TIMI-thrombus grade ≥3 (OR 10.762, 95% CI 1.385–83.635, p = 0.023) were significantly associated with TP. Conclusion Statin at admission, HAVB at admission, and TIMI-thrombus grade ≥3 were associated with TP in patients with inferior STEMI. Although the patients with TP had the higher incidence of RV infarction, the incidence of in-hospital death and long-term MACE was not different between patients with TP and those without.

“…Совершенствование тактики лечения под контролем новых технологий улучшает течение ОИМ. Так, использование в клинической практике реперфузии снижает смертность при ОИМ и в сочетании с инфарктом ПЖ; установка временного электрокардиостимулятора улучшает прогноз при возникновении атриовентрикулярной блокады 2-3 степени [3,4]. Тромболизис и чрескожное коронарное вмешательство (ЧКВ) увеличивают выживаемость пациентов с ОИМ в острый период, но не уменьшают частоту повторных госпитализаций [5].…”
