Comparative StudyImpact of baseline heart failure burden on post-implantable cardioverter-defibrillator mortality among medicare beneficiaries.
This study sought to assess the impact of baseline heart failure (HF) burden on survival with primary implantable cardioverter-defibrillator (ICD) among Medicare recipients. ⋯ Nearly one-third of Medicare ICD recipients died within 3 years, reflecting a population with more advanced age and disease than seen in trial populations for primary prevention ICD. Nearly one-half of Medicare recipients had a low HF burden and had a survival similar to trial ICD recipients. Future research is warranted to understand the effectiveness of primary ICD implantation among Medicare beneficiaries with heavy HF burdens.

Comparative StudyNoninvasive renal sympathetic denervation by extracorporeal high-intensity focused ultrasound in a pre-clinical canine model.
This study investigated the feasibility of noninvasive renal sympathetic denervation (RSD) by using the novel approach of extracorporeal high-intensity focused ultrasound (HIFU). ⋯ Effective RSD was successfully achieved by using the extracorporeal HIFU method in canines. Thus, noninvasive HIFU may be further explored as an important and novel strategy for RSD.

Comparative StudyPatterns of use and comparative effectiveness of bleeding avoidance strategies in men and women following percutaneous coronary interventions: an observational study from the National Cardiovascular Data Registry.
This study sought to compared the use and effectiveness of bleeding avoidance strategies (BAS) by sex. ⋯ Women continue to have almost twice the rate of bleeding following PCI. The use of any BAS was associated with a similarly lower risk of bleeding for men and women; however, the absolute risk differences were substantially higher in women. These data underscore the importance of applying effective strategies to limit post-PCI bleeding, especially in women.
