Abstract
PURPOSE To analyze the impact of chronic obstructive pulmonary disease (COPD) and bronchial asthma on therapeutic management and prognosis of patients with heart failure (HF). METHODS Analysis of the information collected in a clinical registry of patients referred to a specialized HF unit from January-2010 to June-2012. Clinical profile, treatment and prognosis of patients was evaluated, according to the presence of COPD or asthma. Survival analyses were conducted by means of Kaplan-Meier and Cox's methods. Median follow-up was 1493 days. RESULTS We studied 2577 patients, of which 251 (9.7%) presented COPD and 96 (3.7%) bronchial asthma. Significant differences among study groups were observed regarding to the prescription of beta-blockers (COPD=89.6%; asthma=87.5%; no bronchopathy=94.1%; p=0.002) and SGLT2 inhibitors (COPD=35.1%; asthma=50%; no bronchopathy=38.3%; p=0.036). Also, patients with bronchial disease received less frequently a defibrillator (COPD=20.3%; asthma=20.8%; no broncopathy=29%; p=0.004). COPD was independently associated with increased risk of all-cause mortality (HR=1.64; 95% CI 1.33-2.02), all-cause death or HF admission (HR=1.47; 95% CI 1.22-1.76) and cardiovascular death or heart transplantation (HR=1.39; 95% CI 1.08-1.79) as compared with patients with no bronchopathy. Bronchial asthma was not significantly associated with increased risk of adverse outcomes. CONCLUSIONS COPD, but not asthma, is an adverse independent prognostic factor in patients with HF.

Soluble HLA-G levels in heart transplant recipients: Dynamics and correlation with clinical outcomes. Transpl Immunol 2023; 76:101771. [PMID: 36473577 DOI: 10.1016/j.trim.2022.101771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 11/30/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE To describe the evolution of the serum levels of soluble HLA-G (s-HLA-G) during the first 12 months after heart transplantation (HT) and to correlate it with clinical outcomes. METHODS Observational study based in a single-center cohort of 59 patients who underwent HT between December-2003 and March-2010. Soluble HLA-G levels were measured from serum samples extracted before HT, and 1, 3, 6 and 12 months after HT. The cumulative burden of s-HLA-G expression during the first post-transplant year was assessed by means of the area under the curve (AUC) of s-HLA-G levels over time and correlated with the acute rejection burden -as assessed by a rejection score-, the presence of coronary allograft vasculopathy (CAV) grade ≥ 1 and infections during the first post-transplant year; as well as with long-term patient and graft survival. Mean follow-up was 12.4 years. RESULTS Soluble HLA-G levels decreased over the first post-transplant year (p = 0.020). The AUC of s-HLA-G levels during the first post-transplant year was higher among patients with infections vs. those without infections (p = 0.006). No association was found between the AUC of s-HLA-G levels and the burden of acute rejection or the development of CAV. Overall long-term survival, long-term survival free of late graft failure and cancer-free survival were not significantly different in patients with an AUC of s-HLA-G levels higher or lower than the median of the study population. CONCLUSIONS Soluble HLA-G levels decreased over the first year after HT. Higher HLA-G expression was associated with a higher frequency of infections, but not with the burden of acute rejection or the development of CAV, neither with long-term patient or graft survival.

Abstract
AIMS To assess the incidence of cancer diagnosis and cancer-related mortality in patients with heart failure (HF). METHODS Observational study based in a prospective cohort of patients with HF referred to a specialized Spanish clinic between 2010 and 2019. The observed incidence of malignancies (excluding non-melanoma skin cancer) was compared to that expected for the general Spanish population according to the Global Cancer Observatory. RESULTS We studied 1909 consecutive patients with HF. Over a median follow-up of 4.07 years, 165 new cases of malignancy were diagnosed. Observed age-standardized incidence rates of cancer were 861 (95% CI 618.4-2159.4) cases per 100,000 patients-years in men and 728.5 (95% CI 451.1-4308.7) cases per 100,000 patients-years in women; while age-standardized incidence rates of cancer expected for the general Spanish population were 479.4 cases per 100,000 patients-years in men (risk ratio = 1.80) and 295.5 cases per 100,000 patients-years in women (risk ratio = 2.46). Both a history of pre-existing malignancy at baseline and the development of new malignancies during follow-up were associated with reduced survival. Observed age-standardized cancer-related mortality was 344.1 (95% CI 202.1-1675) deaths per 100,000 patient-years in men and 217.0 (95% CI 32.8-3949.3) deaths per 100,000 patient-years in women; while age-standardized cancer-related mortality expected for the general Spanish population was 201.4 deaths per 100,000 patients-years in men (risk ratio = 1.71) and 96.2 deaths per 100,000 patients-years in women (risk ratio = 2.26). CONCLUSION Patients with HF showed higher incidence rates of cancer diagnosis and cancer-related mortality than those expected for the general population.

Epidemiological Study of Tricuspid Regurgitation After Cardiac Transplantation. Does it Influence Survival? Transpl Int 2022; 35:10197. [PMID: 35387398 PMCID: PMC8979064 DOI: 10.3389/ti.2022.10197] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Accepted: 02/17/2022] [Indexed: 01/05/2023]
Abstract
Background: Tricuspid valve disease is the most frequent valvulopathy after heart transplantation (HTx). Evidence for the negative effect of post-transplant tricuspid regurgitation (TR) on survival is contradictory. The aim of this study was to analyze the causes of post-transplant TR and its effect on overall mortality. Methods: This is a retrospective observational study of all transplants performed in two Spanish centers (1009 patients) between 2000 and 2019. Of the total number of patients, 809 had no TR or mild TR and 200 had moderate or severe TR. The etiology of TR was analyzed in all cases. Results: The prevalence of moderate and severe TR was 19.8%. The risk of mortality was greater when TR was caused by early primary graft failure (PGF) or rejection (p < 0.05). TR incidence was related to etiology: incidence of PGF-induced TR was higher in the first period, while TR due to rejection and undefined causes occurred more frequently in three periods: in the first year, in the 10-14-year period following HTx, and in the long term (16-18 years). In the multivariable analysis, TR was significantly associated with mortality/retransplantation (HR:1.04, 95% CI:1.01-1.07, p:0.02). Conclusion: The development of TR after HTx is relatively frequent. The annual incidence depends on TR severity and etiology. The risk of mortality is greater in severe TR due to PGF or rejection.

Abstract
AIMS In the absence of previous direct comparative studies, we aimed to evaluate the effectiveness of spironolactone and eplerenone in patients with heart failure and reduced ejection fraction (HFrEF) in a real-world clinical setting. METHODS Using Fine-Gray´s competing risk regression, we compared the clinical outcomes of 293 patients with chronic HF and left ventricular ejection fraction <40% treated with eplerenone and 293 propensity-score matched individuals treated with spironolactone. Study subjects were selected from a prospective cohort of 1404 ambulatory patients with HFrEF seen since 2010 to 2019 in a single specialized HF clinic, among which 992 received a mineralocorticoid receptor antagonist at baseline. Median follow-up was 3.95 years. RESULTS No statistically significant differences between patients treated with eplerenone versus spironolactone were observed with regard to the risk of the primary composite end-point cardiovascular death or HF hospitalization (HR 0.95; 95% CI 0.73-1.23; p= 0.677). However, eplerenone use was associated to lower cardiovascular mortality (HR 0.55; 95% CI 0.35-0.85; p= 0.008) and lower all-cause mortality (HR 0.67; 95% CI 0.47-0.95; p= 0.027). The incidence of drug suspension due to side effects (HR 0.58, 95% CI 0.40-0.85; p= 0.005) and drug suspension due to any reason (HR 0.70, 95% CI 0.51-0.97; p= 0.033) were lower among patients treated with eplerenone. CONCLUSIONS In this observational, real-world, propensity-score matched study of patients with HFrEF, eplerenone was associated to lower cardiovascular mortality and lower all-cause mortality than spironolactone.

Abstract
INTRODUCTION AND OBJECTIVES The present report describes the clinical characteristics and outcomes of heart transplants in Spain and updates the data to 2019. METHODS We describe the clinical characteristics and outcomes of heart transplants performed in Spain in 2019, as well as trends in this procedure from 2010 to 2018. RESULTS In 2019, 300 transplants were performed (8794 since 1984; 2745 between 2010 and 2019). Compared with previous years, the most notable findings were the decreasing rate of urgent transplants (38%), and the consolidation of the type of circulatory support prior to transplant, with an almost complete disappearance of counterpulsation balloon (0.7%), stabilization in the use of extracorporeal membrane oxygenation (9.6%), and an increase in the use of ventricular assist devices (29.0%). Survival from 2016 to 2018 was similar to that from 2013 to 2015 (P=.34). Survival in both these periods was better than that from 2010 to 2012 (P=.002 and P=.01, respectively). CONCLUSIONS Heart transplant activity has remained stable during the last few years, as have outcomes (in terms of survival). There has been a trend to a lower rate of urgent transplants and to a higher use of ventricular assist devices prior to transplant.

Abstract
INTRODUCTION AND OBJECTIVES To analyze survival in heart failure (HF) patients treated at a specialized unit. METHODS Prospective cohort-based study of HF patients treated at a specialized unit from 2011 to 2017. Observed 1- and 3-year mortality rates were compared with those predicted by the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score. RESULTS We studied 1280 patients, whose median MAGGIC risk score was 19 [interquartile range, 13-24]. Prescription rates of beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, mineralocorticoid receptor antagonists, and sacubitril-valsartan were 93%, 67%, 22%, 73%, and 16%, respectively. The MAGGIC risk score showed good discrimination for mortality at 1 year (c-statistic=0.71) and 3 years (c-statistic=0.76). Observed mortality was significantly lower than predicted mortality, both at 1 year (6.2% vs 10.9%; observed/predicted ratio=0.57; P<.001) and at 3 years (16.7% vs 27.7%; observed/predicted ratio=0.60; P<.001). This discrepancy was found in several subgroups, except in patients aged> 70 years (29.9% vs 34.7%; observed/predicted ratio=0.86; P=.126) and in patients with ejection fraction> 40% (19.6% vs 20.7%; observed/predicted ratio=0.95; P=.640). CONCLUSIONS Mortality in HF patients treated at a specialized clinic was significantly lower than that predicted by the MAGGIC risk score.

Abstract
INTRODUCTION AND OBJECTIVES Light-chain amyloidosis (AL-CA) and transthyretin amyloidosis (ATTR-CA) are the most common types of cardiac amyloidosis (CA). We sought to study the clinical characteristics and prognosis of both diseases. METHODS We conducted a single-centre, retrospective review of all patients diagnosed with CA between 1998 and 2018. Clinical characteristics, complementary tests, survival and other adverse clinical events were studied. RESULTS We identified 105 patients with CA, 65 ATTR-CA and 40 AL-CA. Mean age was 74.4 years; 24.8% were women. In both groups, heart failure was the most frequent clinical presentation (55.2%). The most prevalent electrocardiographic findings were the pseudoinfarct pattern (68.5%) and a Sokolow-Lyon index < 1.5 mV (67.7%), with no differences between the two subtypes of CA. One-year, 3-year, and 5-year survival was 43.3%, 40.4% and 35.4%, respectively, in AC-AL patients, and 85.1%, 57.3% and 31.4% in AC-ATTR patients (p = 0.004). AL-CA subtype (HR 3.41; 95% CI 1.45-8.06; p = 0.005), previous admission for heart failure (HR 4.25; 95% CI 1.63-11.09; p = 0.003) and a NYHA class III-IV (HR 2.76; 95% CI; 1.09-7.03; p = 0.033) were independent predictors of mortality, while beta-blocker therapy was associated with longer survival (HR 0.23; 95% CI 0.09-0.59; p = 0.002). CONCLUSIONS Differences exist between the clinical presentation of AL-CA and ATTR-CA patients. Both diseases, particularly AL-CA, are associated with poor life prognosis.

Abstract
INTRODUCTION AND OBJECTIVES Circulating galectin-3 (Gal-3) is elevated and significantly correlates with all-cause and cardiovascular mortality in patients with heart failure. However, the relationship between serum Gal-3 and heart transplant (HT) outcomes is unclear. The aim of this study was to describe the longitudinal trend and prognostic value of Gal-3 levels after HT. METHODS Banked serum samples were available from 122 HT recipients, collected before transplant and at 1, 3, 6, and 12 months posttransplant. Gal-3 levels in these serum samples were measured by enzyme immune assay. Multivariable Cox regression was performed to determine the prognostic value of 12-month posttransplant Gal-3 serum levels. The primary endpoint was the composite variable all-cause death or graft failure over long-term posttransplant follow-up. RESULTS Circulating Gal-3 concentration steadily decreased during the first year after HT (median values: pretransplant, 19.1 ng/mL; 1-year posttransplant, 14.6 ng/mL; P<.001). Circulating Gal-3 levels 1-year posttransplant were associated with an increased risk of all-cause death or graft failure (adjusted HR per 1 ng/mL, 1.04; 95%CI, 1.01-1.08; P=.008). The predictive accuracy of this biomarker was moderate: area under the ROC curve, 0.72 (95%CI, 0.60-0.82; P<.001). CONCLUSIONS Circulating Gal-3 steadily decreased during the first year after HT. However, 1-year posttransplant Gal-3 serum levels that remained elevated were associated with increased long-term risk of death and graft failure.

Abstract
INTRODUCTION AND OBJECTIVES To study the prognostic impact of preoperative nutritional status, as assessed through the nutritional risk index (NRI), on postoperative outcomes after heart transplantation (HT). METHODS We conducted a retrospective, single-center study of 574 patients who underwent HT from 1991 to 2014. Preoperative NRI was calculated as 1.519 × serum albumin (g/L) + 41.7 × (body weight [kg] / ideal body weight [kg]). The association between preoperative NRI and postoperative outcomes was analyzed by means of multivariable logistic regression and multivariable Cox regression. RESULTS Mean NRI before HT was 100.9 ± 9.9. According to this parameter, the prevalence of severe nutritional risk (NRI < 83.5), moderate nutritional risk (83.5 ≤ NRI < 97.5), and mild nutritional risk (97.5 ≤ NRI < 100) was 5%, 22%, and 10%, respectively. One year post-transplant mortality rates in these 4 categories were 18.2%, 25.3%, 7.9% and 10.2% (P < .001), respectively. The NRI was independently associated with a lower risk of postoperative infection (adjusted OR, 0.97; 95%CI, 0.95-1.00; P = .027) and prolonged postoperative ventilator support (adjusted OR, 0.96; 95%CI, 0.94-0.98; P = .001). Patients at moderate or severe nutritional risk had significantly higher 1-year post-HT mortality (adjusted HR, 1.55; 95%CI, 1.22-1.97; P < .001). CONCLUSIONS Malnourished patients have a higher risk of postoperative complications and mortality after HT. Preoperative NRI determination may help to identify HT candidates who might benefit from nutritional intervention.

Abstract
INTRODUCTION AND OBJECTIVES To assess the potential association between recipient Toxoplasma gondii serostatus and outcomes after heart transplant (HT). METHODS We conducted a retrospective single-center study of 657 HT recipients from 1991 to 2015. Survival and the incidence of adverse clinical events of T. gondii-seropositive (n = 481) vs T. gondii-seronegative (n = 176) recipients were compared by means of 2 different multivariable Cox regression models. Model 1 included solely age and sex, and model 2 included other potential confounders. RESULTS Over a median follow-up of 2903 days (interquartile range: 898-4757), 250 seropositive recipients (52%) and 72 seronegative recipients (41%) died. Univariable analysis showed increased posttransplant mortality among T. gondii-seropositive recipients (hazard ratio [HR] = 1.31; 95% confidence interval [95%CI], 1,00-1.70). After multivariable adjustment, the statistical significance of this association was lost (model 1: HR = 1.09; 95%CI, 0.83-1.43; model 2:HR = 1.12; 95%CI, 0.85-1.47). Recipient T. gondii seropositivity was independently associated with an increased risk of acute rejection (model 1: HR = 1.36; 95%CI, 1.06-1.74; model 2: HR = 1.29; 95%CI, 1.01-1.66). Multivariable models showed no statistically significant impact of recipient T. gondii serostatus on the incidence of infection, malignancy, coronary allograft vasculopathy, or the composite outcome of cardiac death or retransplant. No significant association was found between donor-recipient T. gondii serostatus matching and posttransplant outcome. CONCLUSIONS In this study, recipient T. gondii serostatus was not an independent predictor of long-term post-HT outcome.

Abstract
INTRODUCTION Cardiac allograft vasculopathy (CAV) remains a major impediment to long-term survival after heart transplantation (HT). Limited data exist regarding the impact of coronary revascularization in these patients. OBJECTIVE To evaluate the outcomes of revascularization procedures in patients with CAV compared with patients who did not undergo revascularization. METHODS Retrospective analysis of 249 patients who underwent HT at our center between June 1998 and December 2009 and who were examined by coronary angiography after HT. We included patients with moderate or severe CAV according to the International Society for Heart and Lung Transplantation (ISHLT) nomenclature to evaluated outcomes after revascularization or diagnostic angiography. Major adverse cardiovascular events (MACE) comprised death, acute coronary syndrome, coronary revascularization, admission because of heart failure not due to an acute rejection episode, and cardiac retransplantation. RESULTS Moderate or severe CAV was detected in 43 patients. Twelve (27.9%) underwent coronary revascularization: eight percutaneous interventions and four bypass surgeries. Indications for revascularization were symptomatic ischemia or noninvasive evidence of ischemia (n = 6, 14.0%) or high-risk asymptomatic CAV (n = 6; 14.0%), namely, lesions located in the left main or proximal anterior descending arteries or multivessel disease with left ventricular dysfunction. The remaining 31 (72.1%), who did not undergo revascularization showed an absence of ischemia during exercise echocardiography (n = 11; 25.6%) or diffuse disease not amenable to revascularization (n = 20; 46.5%). During a mean follow-up of 3.0 ± 2.4 years, MACE occurred in three revascularized patients (25.0%), in one with absence of stress-induced ischemia (9.1%) and in 13 with nonrevascularizable disease (65%; P = .012). CONCLUSIONS Revascularization procedures were effective in HT patients with evidence of ischemia or high-risk CAV. Patients with absence of stress-induced ischemia have a good prognosis without revascularization. On the other hand, diffuse nonrevascularizable CAV is associated with a poor prognosis.

Abstract
INTRODUCTION It has been suggested that for adequate maintenance of tacrolimus levels, the total daily dosage should be increased when switching from the conventional twice-daily regimen tacrolimus (CT) to once-daily sustained-release tacrolimus (SR-T). OBJECTIVE To evaluate the safety and efficacy of a 25% increase in daily dosage when switching heart transplant (HT) patients from CT to SR-T. METHODS We switched 75 HT patients including 72% males and an overall mean age of 55.6 years from CT to SR-T using a 25% increase in daily dosage. We screened for adverse events by measurements of lipids, creatinine, glycemia, and tacrolimus in blood samples taken at 1, 3, 7, and 12 weeks after the conversion, as well as by repeated echocardiography and routine clinical examinations. RESULTS Just two patients (2.7%) were returned to CT because of failure of SR-T to attain therapeutic levels. In the remainder of subjects, tacrolimus levels remained stable, with trough values of 8.7±3.2, 8.7±2.9, 8.3±2.6, and 7.5±2.0 mg/dL, respectively. Twenty-three patients (31%) required no dosage change in the first 3 months, but 44 (33%) required one or two changes. No departure from therapeutic levels was associated with rejection; there was no case of severe intercurrent infection. We did not observe significant changes in glycemia, creatinine, lipid profile, or blood pressure. CONCLUSIONS Administration of SR-T at a dosage 25% higher than the daily dosage of CT was safe. It ensured adequate tacrolimus levels in one-third of patients. Nevertheless, strict analytical surveillance is necessary during the initial months to allow dosage adjustments and to detect the minority of patients for whom SR-T does not achieve therapeutic tacrolimus levels.

Abstract
INTRODUCTION AND OBJECTIVES Our aim was to assess the prognostic value of the INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) scale in patients undergoing urgent heart transplantation (HT). METHODS Retrospective analysis of 111 patients treated with urgent HT at our institution from April, 1991 to October, 2009. Patients were retrospectively assigned to three levels of the INTERMACS scale according to their clinical status before HT. RESULTS Patients at the INTERMACS 1 level (n=31) more frequently had ischemic heart disease (P=.03) and post-cardiothomy shock (P=.02) than patients at the INTERMACS 2 (n=55) and INTERMACS 3-4 (n=25) levels. Patients at the INTERMACS 1 level showed higher preoperative catecolamin doses (P=.001), a higher frequency of use of mechanical ventilation (P<.001), intraaortic balloon (P=.002) and ventricular assist devices (P=.002), and a higher frequency of preoperative infection (P=.015). The INTERMACS 1 group also presented higher central venous pressure (P=.02), AST (P=.002), ALT (P=.006) and serum creatinine (P<.001), and lower hemoglobin (P=.008) and creatinine clearance (P=.001). After HT, patients at the INTERMACS 1 level had a higher incidence of primary graft failure (P=.03) and postoperative need for renal replacement therapy (P=.004), and their long-term survival was lower than patients at the INTERMACS 2 (log rank 5.1, P=.023; HR 3.1, IC 95% 1.1-8.8) and INTERMACS 3-4 level (log rank 6.1, p=0.013; HR 6.8, IC 95% 1.2-39.1). CONCLUSIONS Our results suggest that the INTERMACS scale may be a useful tool to stratify postoperative prognosis after urgent HT.

Abstract
INTRODUCTION AND OBJECTIVES Data on chronic anemia following heart transplantation (HT) are scarce and contradictory. Our aims were to determine the prevalence of chronic anemia after HT, to identify predisposing factors for the condition at 12 months, and to evaluate its influence on medium-term and long-term survival. METHODS Retrospective analysis of patients who underwent HT between 1991 and 2005 (n=457). Chronic anemia was defined as a hemoglobin level <12 g/dL. RESULTS The prevalence of post-HT chronic anemia was 75.5% at 1 month, 31% at 12 months, and 26.2% at 120 months. The condition was significantly more prevalent among women than men. Predisposing factors for chronic anemia 1 year post-HT were mild-to-moderate chronic renal failure (i.e., creatinine level >1.5 mg/dL; odds ratio [OR]=2.8; 95% confidence interval [CI], 1.5-5.0), female sex (OR=6.4; 95% CI, 3.1-13.2), and immunosuppression with mycophenolate mofetil compared with azathioprine (OR=2.6;, 95% CI, 1.4-4.8). The prevalence of chronic anemia 12 months after HT was independent of the donor's sex, the recipient's age, the etiology of the recipient's heart failure, diabetes mellitus, mild-to-moderate graft rejection, cytomegalovirus infection, and angiotensin-converting enzyme inhibitor treatment. The presence of chronic anemia 12 months after HT did not influence either long-term survival (mean, 11.5 years with chronic anemia vs. 13.0 years without) or actuarial survival. CONCLUSIONS Post-HT chronic anemia is common, but improves with time and treatment. Predisposing factors for the condition 1 year post-HT include chronic renal failure, female sex, and immunosuppression with mycophenolate mofetil. The presence of chronic anemia does not appear to influence long-term survival.

Long-Term Results of Heart Transplant in Recipients Older and Younger Than 65 Years: A Comparative Study of Mortality, Rejections, and Neoplasia in a Cohort of 445 Patients.

Abstract
BACKGROUND Whether being older than 65 years should be considered an absolute counterindication to heart transplant (HT), as it is in some centers, is controversial. In our centre, patients older than 65 years are accepted for HT if they satisfy stringent conditions. The aim of this study was to examine whether heart recipients older than 65 years have a greater risk of rejection, neoplasia, or mortality than younger ones. METHODS We studied 445 patients who underwent HT between April 1991 and December 2003, 42 of whom were older than 65 years and 403 who were 65 years or younger. The parameters evaluated were the cumulative incidences of neoplasias and rejections (ISHLT grade > or = 3A), and the survival rates 1 month, 1 year, and 5 years post-HT. RESULTS The two groups had similar percentages of patients with at least one rejection episode (< or =65 years 56.9%, >65 years 51.3%; P > .05), and although there were proportionally almost twice as many tumors in the older group (14.2%) as in the younger (7.9%), this difference was not statistically significant either. Nor were there any significant differences in survival, the 1-month, 1-year, and 5-year rates being 87.8%, 82.1%, and 68.8%, respectively, in the younger group and 85.7%, 78.6%, and 73.4%, respectively, in the older. CONCLUSIONS Among carefully selected patients aged more than 65 years, HT can be performed without incurring greater risk of rejection, malignancy, or death than is found among recipients younger than 65 years.
