Multicenter Study Comparative Study Observational Study
Implantable cardioverter-defibrillator therapy among patients with non-ischaemic vs. ischaemic cardiomyopathy for primary prevention of sudden cardiac death.
The magnitude of benefit related to implantable cardioverter defibrillator (ICD) therapy for primary prevention of sudden cardiac death (SCD) in non-ischaemic cardiomyopathy (NICM) and ischaemic cardiomyopathy (ICM) has not been evaluated extensively in clinical practice. ⋯ NCT 01992458.

Atrial fibrillation (AF) is the most common arrhythmia and prevalence increases with age. Patients with AF have a high risk of stroke, and screening for AF is recommended in all people aged 65 years or older to identify patients eligible for stroke prevention. A handheld, single-lead electrocardiogram (ECG) device can be used for systematic screening in the population at risk. The objective of this study is to estimate the cost-effectiveness of screening for AF in primary care with the MyDiagnostick® during seasonal influenza vaccination in the Netherlands. ⋯ Screening for AF in primary care with a handheld, single-lead ECG during seasonal influenza vaccination is very likely to be cost saving for identifying new cases of AF in the Dutch population aged 65 years and over. Active screening for AF with a single-lead, handheld ECG device during seasonal influenza vaccination could be implemented in primary care.

Observational Study
Cardiac resynchronization therapy in patients with end-stage hypertrophic cardiomyopathy.
A dilated/end-stage phase of hypertrophic cardiomyopathy (HCM) is rare but well-recognized. The role for cardiac resynchronization therapy (CRT) in this subset of patients remains unexplored. We aimed to clarify the impact of bi-ventricular pacing CRT in dilated/end-stage HCM. ⋯ CRT in patients with dilated/end-stage HCM does not appear to confer a salutary effect on ventricular function. In medium-term follow-up, however, left ventricular function did not appear to deteriorate further, yet advanced heart failure therapy was common in this group.

Observational Study
Relation of renal dysfunction with incident atrial fibrillation and cardiovascular morbidity and mortality: The PREVEND study.
Renal dysfunction is a risk factor for cardiovascular disease, including atrial fibrillation (AF) and mortality. However, the exact pathobiology linking different renal dysfunction measures, such as albumin excretion or glomerular filtration rate (GFR), to cardiovascular- and AF risk are unclear. In this study, we investigated the association of several renal function measures and incident AF, and whether the relation between renal measures and outcomes is modified by AF. ⋯ In this community-based cohort, increased albumin excretion, and not GFR, was associated with incident AF, independent of established cardiovascular risk factors. Incidence of AF did not largely alter the association of renal dysfunction and cardiovascular outcomes.

Catheter ablation to achieve posterior left atrial wall (PW) isolation may be performed as an adjunct to pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (AF). We aimed to determine whether routine adenosine challenge for dormant posterior wall conduction improved long-term outcome. ⋯ Posterior left atrial wall isolation in addition to PVI is a readily achievable ablation strategy in patients with persistent AF. Routine adenosine challenge for dormant posterior wall conduction was associated with an improvement in the success of catheter ablation for persistent AF.
