Stroke Prevention in Very Elderly Patients With Nonvalvular Atrial Fibrillation Revisited

Chronological vs Biological Age in Interventional Cardiology: A Comprehensive Approach to Care for Older Adults: JACC Family Series

Aging is the gradual decline in physical and physiological functioning leading to increased susceptibility to stressors and chronic illnesses, including cardiovascular disease. With an aging global population, in which 1 in 6 individuals will be older than 60 years by 2030, interventional cardiologists are increasingly involved in providing complex care for older individuals. Although procedural aspects remain their main clinical focus, interventionalists frequently encounter age-associated risks that influence eligibility for invasive care, decision making during the intervention, procedural adverse events, and long-term management decisions. The unprecedented growth in transcatheter interventions, especially for structural heart diseases at extremes of age, have pushed age-related risks and implications for cardiovascular care to the forefront. In this JACC state-of-the-art review, the authors provide a comprehensive overview of the aging process as it relates to cardiovascular interventions, with special emphasis on the difference between chronological and biological aging. The authors also address key considerations to improve health outcomes for older patients during and after their invasive cardiovascular care. The role of "gerotherapeutics" in interventional cardiology, technological innovation in measuring biological aging, and the integration of patient-centered outcomes in the older adult population are also discussed.

Left Atrial Appendage Occlusion in the Elderly: Insights From PROTECT-AF, PREVAIL, and Continuous Access Registries

BACKGROUND

Data on the safety and efficacy of left atrial appendage occlusion (LAAO) in elderly patients are limited.

OBJECTIVES

We aimed to compare the outcomes of LAAO between patients ≥80 and <80 years of age.

METHODS

We included patients enrolled in randomized trials and nonrandomized registries of the Watchman 2.5 device. The primary efficacy endpoint was a composite of cardiovascular/unknown death, stroke, or systemic embolism at 5 years. Secondary endpoints included cardiovascular/unknown death, stroke, systemic embolism, and major and nonprocedural bleeding. Survival analyses were performed using the Kaplan-Meier, Cox proportional hazards, and competing risk analysis methods. Interaction terms were used to compare the 2 age groups. We also estimated the average treatment effect of the device with the use of inverse probability weighting.

RESULTS

We studied 2,258 patients, of whom 570 (25.2%) were ≥80 years old, and 1,688 (74.8%) were <80 years old. Procedural complications at 7 days were similar in both age groups. The primary endpoint occurred in 12.0% in the device group vs 13.8% in the control group (HR: 0.9; 95% CI: 0.6-1.4) among patients <80 years of age and in 25.3% vs 21.7%, respectively (HR: 1.2; 95% CI: 0.7-2.0) among patients ≥80 (interaction P value = 0.48). There was no interaction between age and treatment effect for any of the secondary outcomes. The average treatment effects of LAAO (compared with warfarin) were similar in the elderly population (compared with younger patients).

CONCLUSIONS

Despite the higher event rates, octogenarians derive similar benefits from LAAO as their younger counterparts. Age alone should not preclude LAAO in otherwise suitable candidates.

The Heart Brain Team and Patient-Centered Management of Ischemic Stroke

The multifaceted connections between the heart and the brain have been extensively studied at the anatomy, pathophysiology, and clinical levels. Studies have suggested a vital role for both cardiologists and neurologists in the management of various cardiovascular and neurological disorders. However, a true heart-brain team-based approach remained confined to large, specialized centers. In this paper, we review the various intersection areas of cardiology and neurology with regard to ischemic stroke. We focus our discussion on the challenges and opportunity for a heart-team approach to stroke in the context of atrial fibrillation, carotid disease, and patent foramen ovale, and in the setting of strokes complicating transcatheter endovascular interventions.
