Joint shock/death risk prediction model for patients considering implantable cardioverter-defibrillators.
This study’s goal was to develop a joint shock/death risk prediction tool for patients who received implantable cardioverter-defibrillators (ICDs). Secondary analysis of patients was conducted as part of the SCD-HeFT trial (Sudden Cardiac Death in Heart Failure Trial). An illness-death regression model was applied for both ICD shocks and deaths. Among 803 ICD recipients, 430 (53.5%) did not receive an ICD shock or die, 206 (25.7%) received at least 1 shock but did not die, 113 (14.1%) died before receiving a shock, and 54 (6.7%) received at least 1 shock but still died. This predictive performance can be used as a tool for individualized counseling for patients contemplating an ICD.

Influence of multimorbidity on burden and appropriateness of implantable cardioverter-defibrillator therapies.
Researchers sought to determine whether burden of multiple chronic conditions (MCCs) influences the risk of receiving inappropriate vs appropriate device therapies. They studied adults with left ventricular systolic dysfunction receiving an implantable cardioverter-defibrillator (ICD) for primary prevention. In these patients, they found that MCC burden was independently associated with an increased risk of inappropriate but not appropriate device therapies. They recommended considering comorbidity burden when engaging patients in shared decision making about ICD implantation.
