The Relationship of Conduction Disorder and Prognosis in Patients with Acute Coronary Syndrome

Figure 2

Kaplan–Meier curve analysis for heart failure (HF) hospitalization, cardiovascular (CV) mortality, and all-cause mortality among the patients with left bundle branch block (LBBB), right bundle branch block (RBBB), and nonspecific intraventricular conduction delay (NICD) after propensity score matching during the 3-year follow-up period. (a): Between three groups, highest incidence of HF hospitalization is noted in patients with LBBB after propensity score matching (LBBB vs. RBBB vs. NICD; 27.91% vs. 17.78% vs. 24.14%; ). (b): Between three groups, lowest incidence of CV mortality is noted in patients with RBBB after propensity score matching (LBBB vs. RBBB vs. NICD; 20.13% vs. 16.50% vs. 20.69%; ). (c): Between three groups, lowest incidence of all-cause mortality is noted in the patients with RBBB after propensity score matching (LBBB vs. RBBB vs. NICD; 41.23% vs. 37.22% vs. 41.81%; ).
