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.

Assessment of patients' and caregivers' informational and decisional needs for left ventricular assist device placement: implications for informed consent and shared decision-making.
The authors investigated the decision-making process and informational and decisional needs of patients and their caregivers regarding left ventricular assist device (LVAD) placement. They found that participants easily and clearly identified their values: life extension; family; and mobility. Participants reported the need to meet other patients and caregivers before device placement and to have an involved caregiver to synthesize information. They further found that some participants demonstrated a lack of clarity regarding transplant probability.

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.

Implantable cardioverter-defibrillator use among Medicare patients with low ejection fraction after acute myocardial infarction.
This study examined Implantable Cardioverter-Defibrillator (ICD) implantation rates and associated mortality among older MI patients with low ejection fraction (EF). It found that fewer than 1 in 10 eligible patients with low EF received an ICD within 1 year after MI, although ICD implantation was associated with lower risk-adjusted mortality at 2 years.

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.
