Background: The risks of heart failure (HF) events compared with stroke/systemic embolic events (SEE) or major bleeding (MB) in heart failure with reduced ejection fraction (HFrEF) vs heart failure with preserved ejection fraction (HFpEF) in a large atrial fibrillation (AF) population have not been well-studied.
Objectives: This study sought to assess HF outcomes, according to HF history and HF phenotypes (HFrEF vs HFpEF), and compare these events with SEE and MB, among patients with AF.
Methods: We analyzed patients enrolled in the ENGAGE-AF TIMI 48 (Effective Anticoagulation with Factor Xa Next Generation in AF-Thrombolysis in Myocardial Infarction 48) trial. Cumulative incidence of heart failure hospitalization (HHF) or HF death was assessed and compared with the rates of fatal and nonfatal stroke/SEE and MB over a median follow-up of 2.8 years.
Results: Overall, 12,124 (57.4%) had a history of HF (37.7% HFrEF, 40.1% HFpEF, 22.1% with unknown ejection fraction). The rate per 100 person-years (py) of HHF or HF death (4.95; 95% CI: 4.70-5.20) was higher than of fatal and nonfatal stroke/SEE (1.77; 95% CI: 1.63-1.92) and MB (2.66; 95% CI: 2.47-2.86) among patients with HF history. HFrEF patients experienced a higher rate of HHF or HF death compared with HFpEF patients (7.15 vs 3.65; P < 0.001), while the rates of fatal and nonfatal stroke/SEE and MB were similar by HF phenotype. Patients with HF history had a higher rate of mortality after a HHF (1.29; 95% CI: 1.17-1.42) than after a stroke/SEE (0.69; 95% CI: 0.60-0.78) or after MB (0.61; 95% CI: 0.53-0.70). Overall, patients with nonparoxysmal AF had a higher rate of HF and stroke/SEE events regardless of HF history.
Conclusions: Patients with AF and HF, regardless of ejection fraction, are at a higher risk of HF events with higher subsequent mortality rates than of stroke/SEE or MB. While HFrEF is associated with a higher risk of HF events than HFpEF, the risk of stroke/SEE and MB is similar between HFrEF and HFpEF.

Background: Programmed electrical stimulation (PES) is an essential part of ventricular tachycardia (VT) ablation procedures, but VT is not always inducible, usually for reasons that are not clear.
Objectives: This study sought to review pacing site-specific failure of PES to induce scar-related VT and to provide a potential mechanistic explanation of the phenomena using a computer simulation.
Methods: Six patients in whom aggressive PES from traditional RV pacing sites failed to induce VT, but VT was easily inducible from a nontraditional site, were reviewed.

Diabetes is becoming more common worldwide, and people with diabetes are twice as likely to experience heart problems compared to those without diabetes. These cardiovascular complications are the foremost cause of mortality among people with diabetes. A specific form of heart failure known as "diabetic cardiomyopathy" can develop in individuals with diabetes.
