Standardized Definitions for Cardiogenic Shock Research and Mechanical Circulatory Support Devices: Scientific Expert Panel From the Shock Academic Research Consortium (SHARC).

The Shock Academic Research Consortium is a multi-stakeholder group, including representatives from the US Food and Drug Administration and other government agencies, industry, and payers, convened to develop pragmatic consensus definitions useful for the evaluation of clinical trials enrolling patients with cardiogenic shock, including trials evaluating mechanical circulatory support devices. Several in-person and virtual meetings were convened between 2020 and 2022 to discuss the need for developing the standardized definitions required for evaluation of mechanical circulatory support devices in clinical trials for cardiogenic shock patients. The expert panel identified key concepts and topics by performing literature reviews, including previous clinical trials, while recognizing current challenges and the need to advance evidence-based practice and statistical analysis to support future clinical trials.

Sex-specific Long-term Outcomes of Watchman Left Atrial Appendage Closure for Stroke Prevention in Atrial Fibrillation.

Background: A recent analysis of a large registry showed differences in periprocedural outcomes of the Watchman left atrial appendage closure device in males compared with females. The objective of our study was to investigate the 5-year event rate in males and females enrolled in the Watchman device premarket clinical studies submitted for US Food and Drug Administration review.

Methods: We conducted a patient-level meta-analysis of 2256 patients from 4 studies: the PROTECT AF (Embolic Protection in Patients with Atrial Fibrillation) and PREVAIL (Prospective Randomized Evaluation of the Watchman Left Atrial Appendage Closure Device in Patients with Atrial Fibrillation vs Long-Term Warfarin Therapy) randomized controlled trials and their continued-access registries-CAP1 (Continued Access to PROTECT AF) and CAP2 (Continued Access to PREVAIL).

Frailty and cardiovascular outcomes in the National Health and Aging Trends Study.

Aims: Physical frailty is a commonly encountered geriatric syndrome among older adults without coronary heart disease (CHD). The impact of frailty on the incidence of long-term cardiovascular outcomes is not known.We aimed to evaluate the long-term association of frailty, measured by the Fried frailty phenotype, with all-cause-mortality and MACE among older adults without a history of CHD at baseline in the National Health and Aging Trends Study.

Physical Frailty Phenotype and the Development of Geriatric Syndromes in Older Adults with Coronary Heart Disease.

Background: Frailty, a clinical state of vulnerability, is associated with subsequent adverse geriatric syndromes in the general population. We examined the long-term impact of frailty on geriatric outcomes among older patients with coronary heart disease.

Methods: We used the National Health and Aging Trends Study, a prospective cohort study linked to a Medicare sample.

Transcatheter Aortic Valve Replacement in Low-Population Density Areas: Assessing Healthcare Access for Older Adults With Severe Aortic Stenosis.

Background: Restricting transcatheter aortic valve replacement (TAVR) to centers based on volume thresholds alone can potentially create unintended disparities in healthcare access. We aimed to compare the influence of population density in state of Florida in regard to access to TAVR, TAVR utilization rates, and in-hospital mortality.

Methods And Results: From 2011 to 2016, we used data from the Agency for Health Care Administration to calculate travel time and distance for each TAVR patient by comparing their home address to their TAVR facility ZIP code.
