Background: In 2006, the International Society for Heart and Lung Transplantation amended the guidelines for the upper age limit of heart transplantation (HTx) from 55 years to 70 years and older for carefully selected patients. However, the relation of age to outcomes following of HTx has not been well studied.

Objectives: To investigate the impact of recipient age on the occurrence of rejections, vasculopathy, and mortality after HTx.

Methods: Study population comprised all consecutive 291 patients who underwent HTx between 1991–2016 and were followed at our center. Patients were categorized by age tertiles: < 46 years (mean 31.4 ± 11.7, range 16–45, n=90), 46–57 years (mean 51.4 ± 3.2, range 46–56, n=92), and ≥ 57 years (mean 61.6 ± 3.4, range 57–73, n=109).

Results: Patients aged ≥ 57 years were more often males and had more pre-HTx co-morbidities including hypertension, diabetes, dyslipidemia, and history of smoking (P < 0.05) compared to the younger age groups. Kaplan-Meier analysis by age tertiles showed the rates of major rejections and vasculopathy at 15 years were similar among the three age groups. Mortality rates at 15 years were directly related to the age groups (39%, 52%, 62% log-rank, P = 0.01). However, the association between age and mortality was no longer statistically significant after multivariate analysis (hazard ratio 1.01, 95% confidence interval 1.00–1.03).

Conclusions: In a contemporary cohort of patients undergoing HTx, recipient age does not significantly impact the risk of major rejections, vasculopathy, and long-term mortality.

Background: Heart transplantation (HT) is the treatment of choice for patients with end-stage heart failure. The HT unit at the Sheba Medical Center is the largest of its kind in Israel.

Objectives: To evaluate the experience of HT at a single center, assess trends over 3 decades, and correlate with worldwide data.

Methods: Between 1990 and 2017, we reviewed all 285  adult HT patients. Patients were grouped by year of HT: 1990–1999 (decade 1), 2000–2009 (decade 2), and 2010–2017 (decade 3).

Results: The percentage of women undergoing HT has increased and etiology has shifted from ischemic to non-ischemic cardiomyopathy (10% vs. 25%, P = 0.033; 70% vs. 40% ischemic, for decades 1 vs. 3, respectively). Implantation of left ventricular assist device as a bridge to HT has increased. Metabolic profile has improved over the years with lower low-density lipoprotein, diabetes, and hypertension after HT (101 mg/dl, 27%, and 41% at decade 3, respectively). There has been a prominent change in immunosuppressive treatments, currently more than 90% are treated with tacrolimus, compared with 2.7% and 30.9% in decades 1 and 2, respectively (P < 0.001). Cardiac allograft vasculopathy (CAV) rates have declined significantly (47% vs. 17.5% for decades 1 and 2, P < 0.001) as have the combined endpoint of CAV/death. Similarly, the current incidence of acute rejections is significantly lower.

Conclusions: Our analysis of over 25 years of a single-center experience with HT shows encouraging improved results, which are in line with worldwide standards and experience.

Lower extremity ulcers are a late complication of connective tissue diseases and occur more commonly in patients with this disease than in the general population. Although these lesions have historically been attributed to vasculitis, it is now recognized that inflammatory vessel injury accounts for fewer than 20% of ulcers in connective tissue disease. The pathogenesis of these lesions is complex, and often several processes act synergistically to initiate and perpetuate tissue injury. We review the evidence for antiphospholipid antibodies and prothrombotic states contributing to a vasculopathy in patients with connective tissue disease, precipitating ulceration and impairing healing.
