“…Briefly, 1820 patients with ischaemic cardiomyopathy [New York Heart Association (NYHA) functional class I or II] or non‐ischaemic cardiomyopathy (NYHA functional class II only), LVEF of less than 30%, and a QRS duration >130 ms were randomized to receive CRT‐D or ICD therapy in a 3:2 ratio. All eligible patients met the guideline criteria for ICD 4. Patients were excluded if they had an indication for CRT, implanted pacemaker; NYHA III/IV class in the past 90 days; or coronary artery bypass graft surgery, percutaneous coronary intervention or myocardial infarction within the past 90 days.…”

AimsThere are limited data on whether clinical presentation at first heart failure (HF) hospitalization predicts recurrent HF events. We aimed to assess predictors of recurrent HF hospitalizations in mild HF patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator.Methods and resultsData on HF hospitalizations were prospectively collected for patients enrolled in MADIT‐CRT. Predictors of recurrent HF hospitalization (HF2) after the first HF hospitalization were assessed using Cox proportional hazards regression models including baseline covariates and clinical presentation or management at first HF hospitalization. There were 193 patients with first HF hospitalization, and 156 patients with recurrent HF events. Recurrent HF rate after the first HF hospitalization was 43% at 1 year, 52% at 2 years, and 55% at 2.5 years. Clinical signs and symptoms, medical treatment, or clinical management of HF at first HF admission was not predictive for HF2. Baseline covariates predicting recurrent HF hospitalization included prior HF hospitalization (HR = 1.59, 95% CI: 1.15–2.20, P = 0.005), digitalis therapy (HR = 1.58, 95% CI: 1.13–2.20, P = 0.008), and left ventricular end‐diastolic volume >240 mL (HR = 1.62, 95% CI: 1.17–2.25, P = 0.004).ConclusionsRecurrent HF events are frequent following the first HF hospitalization in patients with implanted implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator. Neither clinical presentation nor clinical management during first HF admission was predictive of recurrent HF. Prior HF hospitalization, digitalis therapy, and left ventricular end‐diastolic volume at enrolment predicted recurrent HF hospitalization, and these covariates could be used as surrogate markers for identifying a high‐risk cohort.

“…The most recent US guidelines for secondary prevention ICDs, published in 2008,2 include a Class IA recommendation for an ICD in patients surviving cardiac arrest due to documented VF or hemodynamically unstable sustained VT after evaluation to exclude any completely reversible causes. A Class IB recommendation is given for those with structural heart disease and spontaneous sustained VT and for patients with syncope of undetermined origin with hemodynamically significant sustained VT or VF induced during programmed ventricular stimulation (Class IB).…”

“…Among patients with an aborted episode of sudden cardiac arrest (SCA) due to ventricular arrhythmias without a reversible cause, the ICD is considered an important therapy for secondary prevention of SCA and is supported by class IA guideline recommendations in selected patients 2. In the United States, a quarter of ICD procedures included in the National Cardiovascular Data Registry (NCDR) ICD Registry are performed for secondary prevention indications 3.…”
