Figure 2 Survival After ICD Insertion by HF and Comorbidity Status
Kaplan-Meier survival plots for implantable cardioverter-defibrillator (ICD) recipients with or without heart failure (HF) and/or model comorbidities (Comorb). The presence of prior heart failure or model comorbidity (e.g., peripheral vascular disease, chronic pulmonary disease, renal disease, rheumatologic disease, microvascular complications of diabetes, or cancer) significantly worsened survival compared with patients who were free of these conditions (log rank p < 0.001).
