P6471Pronostic impact of significant valvular disease in long-term survivors of out-of-hospital-cardiac arrest

Abstract

Abstract Background There is scarce evidence about the prevalence and clinical relevance of moderate to severe valvular heart disease (VHD) in survivors of out of hospital cardiac arrest (OHCA). Purpose To determine whether VHD influence prognosis of OHCA survivors. Methods All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA and surviving until hospital discharge were included. All patients received targeted-temperature management according to our local protocol. Univariate and multivariate Cox-proportional hazard models were employed. Results A total of 201 patients were included in the analysis. Mean age was 57.6±14.2 years and 168 (83.6%) were male. Eighteen patients (9.0%) had moderate or severe VHD during index admission (Table 1). Patients with VHD were less frequently of male sex, [11 (61.1%) vs 157 (85.8%), p=0.014], experienced less acute coronary syndrome-related arrhytmias [2 (11.1%) vs 85 (46.5%), p=0.005], and had a lower pH at hospital admission (6.9±1.6 vs 7.2±0.15, p=0.008). During a median follow-up of 40.3 (18.9–69.1) months, patients with VHD showed higher mortality [7 (38.9%) vs 28 (15.3%), p=0.004] and more heart failure-related admissions [7 (38.9%) vs 15 (8.2%), p<0.001]. Only five patients received surgical or percutaneous treatment for VHD during follow-up, with no deaths in this subgroup. Moderate or severe VHD proved to be an independent predictor of global cardiovascular events and specifically heart failure episodes (Figure 1).

Specific management of VHD may be specially relevant in this high-risk patients and guideline-oriented therapy, including surgery and percutaneous intervention should be encouraged when indicated.
