The role of estrogen, immune function and aging in heart transplant outcomes.

BACKGROUND: Aging and loss of estrogen suppress immune function, potentially improving survival after orthotopic heart transplant (OHT). The effect of female aging on OHT outcomes is unknown. METHODS: Between 1995 and 2015, 41,299 adult OHT recipients (24.3% women) were studied using a retrospective multi-institutional cohort. Patients were stratified by age and gender into premenopausal (18-39 years), perimenopausal (40-49 years), and postmenopausal (≥50 years) groups. Kaplan-Meier survival analyses and risk-adjusted models examined gender differences across groups at one, five, and ten years. RESULTS: Kaplan-Meier survival was equivalent for postmenopausal women and men, and lower for premenopausal women than men at all time points (p ≤ 0.05). Postmenopausal women had higher risk-adjusted five-year survival than premenopausal women (AOR 1.61, 95% CI 1.15-2.25, p = 0.006). CONCLUSIONS: Premenopausal women have lower unadjusted survival than men after OHT. Post-menopausal women have significantly better five-year survival than pre-menopausal women. Menopause may contribute to improved survival after OHT

When Life Gives You Lemons, Make Lemonade: The Case of Hosting the Most Successful Regional Cardiovascular Symposium during the COVID19 Pandemic –– A Tale from the Oregon Chapter of the American College of Cardiology

The Sars-Cov-2 (COVID-19) pandemic has created unprecedented challenges, and revamped the way we live and work. Overall, this pandemic and its isolating consequences has forced societies to become more creative and develop new ways to engage. Professionally, employees are more secluded with attempts to work from home, while in the medical community, physicians have needed to either be on the frontlines treating patients or have adapted to interacting with patients virtually. Even with today’s technological advances to virtually connect with patients, physicians have had to relearn and re-engage

Physiologic risk stratification is important to long-term mortality, complications, and readmission in thoracic endovascular aortic repair

Use of the American Society of Anesthesiologists (ASA) physical status classification is important for periprocedural risk stratification. However, the collective effect after adjustment for the Society for Vascular Surgery (SVS) medical comorbidity grading system on long-term all-cause mortality, complications, and discharge disposition is unknown. We examined these associations in patients after thoracic endograft placement. Data from three thoracic endovascular aortic repair (TEVAR) trials through 5 years of follow-up were included. Patients with acute complicated type B dissection (n = 50), traumatic transection (n = 101), or descending thoracic aneurysm (n = 66) were analyzed. The patients were stratified into three groups according to the ASA class: I-II, III, and IV. Multivariable proportional hazards regression models were used to examine the effect of ASA class on 5-year mortality, complications, and rehospitalizations after adjustment for SVS risk score and potential confounders. The largest proportion of patients treated by TEVAR across the ASA groups (n = 217) was ASA IV (n = 97; 44.7%; P < .001), followed by ASA III (n = 83; 38.2%) and ASA I-II (n = 37; 17.1%). Among the ASA groups, the ASA I-II patients were, on average, 6 years younger than those with ASA III and 3 years older than those with ASA IV (ASA I-II: age, 54.3 ± 22.0 years; ASA III: age, 60.0 ± 19.7 years; ASA IV: age, 51.0 ± 18.4 years; P = .009). Multivariable adjusted 5-year outcome models showed that ASA class IV, independent of the SVS score, conferred an increased risk of mortality (hazard ratio [HR], 3.83; 95% confidence interval [CI], 1.19-12.25; P = .0239) and complications (HR, 4.53; 95% CI, 1.69-12.13; P = .0027) but not rehospitalization (HR, 1.84; 95% CI, 0.93-3.68; P = .0817) compared with ASA class I-II. Procedural ASA class is associated with long-term outcomes among post-TEVAR patients, independent of the SVS score. The ASA class and SVS score remain important to patient counseling and postoperative outcomes beyond the index operation
