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.

Real world effectiveness of primary implantable cardioverter defibrillators implanted during hospital admissions for exacerbation of heart failure or other acute co-morbidities: cohort study of older patients with heart failure.
The researchers examined the effectiveness of primary implantable cardioverter defibrillators (ICDs) in elderly patients receiving the device during a hospital admission for exacerbation of heart failure or other acute co-morbidities. They concluded that the benefits of primary ICD therapy seen in pivotal trials were not apparent in patients aged 66 or over who received ICDs during a hospital admission for exacerbation of heart failure or other acute co-morbidities.

Does age influence cardiac resynchronization therapy use and outcome?
This study sought to describe the use of cardiac resynchronization therapy with defibrillator (CRT-D) and its association with survival for older patients. It found that receipt of CRT-D was associated with better survival at 1 year (82.1 percent vs. 77.1 percent, respectively) and 4 years (54.0 percent vs. 46.2 percent , respectively) than in those receiving only an implantable cardiac defibrillator.
