RESUMEN

The study of gender differences may lead into improvement in patient care. We have aimed to identify the gender differences in heart transplantation (HT) of adult HT recipients in Spain and their evolution in a study covering the years 1993-2017 in which 6740 HT (20.6% in women) were performed. HT indication rate per million inhabitants was lower in women, remaining basically unchanged during the 25-year study period. HT rate was higher in men, although this decreased over the 25-year study period. Type of heart disease differed in men versus women (p < .001): ischemic heart disease 47.6% versus 22.5%, dilated cardiomyopathy 41.3% versus 34.6%, or other 36% versus 17.8%, respectively. Men were more frequently diabetics (18% vs. 13.1% p < .001), hypertensives (33.1% vs. 24% p < .001), and smokers (21.7% vs. 12.9% p < .001), respectively. Women had more pre-HT malignancies (7.1% vs. 2.8% p < .001), and their clinical status was worse at HT due to renal function and mechanical ventilation. Adjusted survival (p = .198) and most of the mortality-related variables were similar in men and women. Death occurred more frequently in women due to rejection (7.9% vs. 5.1% p < .001) and primary failure (18.2% vs. 12.5% p < .001) and in men due to malignancies (15.1% vs. 6.6% p < .001).

RESUMEN

PURPOSE: Our objective was to investigate the impact of inter-vendor variability in the ability of myocardial strain analysis to detect acute cellular rejection (ACR) in heart transplant recipients. METHODS: We performed serial echocardiographic examinations in 18 consecutive adult heart transplanted patients, in their first year post-transplantation, within 3 hours of the routine surveillance endomyocardial biopsies (EMB) in a single center. Myocardial strain was analyzed using two software in two different institutions, and inter-vendor variability of strain values and its association with ACR (any grade or grade ≥2R) was investigated. The parameter of comparison was the peak value of the average curve of strain during the entire cardiac cycle. RESULTS: A total of 147 pairs of EMB-echocardiogram were performed, 65 with no ACR, 63 with ACR grade 1R, and 19 with ACR grade ≥2R. Intra-class correlation coefficients for left ventricle longitudinal, radial, and circumferential strain were 0.38, 0.39, and 0.77, respectively, and 0.32 for right ventricular longitudinal strain. Neither software found significant association of left ventricular longitudinal strain with rejection. Grade ≥2R ACR was associated with left ventricular circumferential strain measured with the first software and with left ventricular radial strain with the other; and ACR of any grade was only significantly associated with right ventricle longitudinal strain measured with the first software. CONCLUSIONS: Inter-vendor reproducibility of strain values was low in this study. Some strain parameters were associated to ACR, although these results were inconsistent between two commercially available software. Specific validation of each software is warranted for this clinical indication.

RESUMEN

AIMS: Cardiac resynchronization therapy (CRT) reduces the incidence of sudden cardiac death and the use of appropriate implantable cardioverter-defibrillator (ICD) therapies (AICDTs); however, this antiarrhythmic effect is only observed in certain groups of patients. To gain insight into the effects of CRT on ventricular arrhythmia (VA) burden, we compared the incidence of AICDT use in four groups of patients: patients with ischaemic cardiomyopathy vs. non-ischaemic dilated cardiomyopathy (NIDC) and patients implanted with an ICD vs. CRT-ICD. METHODS AND RESULTS: We analysed 689 consecutive patients (mean follow-up 37 ± 16 months) included in the Umbrella registry, a multicentre prospective registry including patients implanted with ICD or CRT-ICD devices with remote monitoring capabilities in 48 Spanish Hospitals. The primary outcome was the time to first AICDT. Despite a worse clinical risk profile, NIDC patients receiving a CRT-ICD had a lower cumulative probability of first AICDT use at 2 years compared with patients implanted with an ICD [24.7 vs. 41.6%, hazard ratio (HR): 0.49, P = 0.003]; on the other hand, there were no significant differences in the incidence of first AICDT use at 2 years in ischaemic patients (22.6 vs. 21.9%, P = NS). Multivariate analysis confirmed the association of CRT with lower AICDT rates amongst NIDC patients (Adjusted HR: 0.55, CI 95% 0.35-0.87). CONCLUSIONS: These data suggest that CRT is associated with significantly lower rates of first AICDT use in NIDC patients, but not in ischaemic patients. This study suggests that ICD patients with NIDC and left bundle branch block experiencing VAs may benefit from an upgrade to CRT-ICD despite being in a good functional class.

RESUMEN

The results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 ± 4.1 vs. 24.3 ± 3.7; P < 0.01), and male donors were younger than female donors (33.4 ± 12.7 vs. 38.2 ± 12.3; P < 0.01). No further relevant differences related to donor sex were detected. In the univariate analysis, mismatch was associated with mortality in men (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.06-1.32; P = 0.003) but not in women (HR, 0.91; 95% CI 0.74-1.12; P = 0.4). A significant interaction was detected between sex mismatch and recipient gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with long-term mortality (HR, 1.14; 95% CI 1.01-1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women.

RESUMEN

BACKGROUND: Our objective was to evaluate the impact of asymptomatic acute cellular rejection (ACR) in left ventricular myocardial strain in heart transplant (HT) recipients by means of two-dimensional speckle tracking echocardiography (2DSTE). METHODS: From September 1, 2009 to December 15, 2010 a conventional echocardiography and 2DSTE exam was performed on all consecutive HT recipients in their first year posttransplantation within 3 hours of the surveillance endomyocardial biopsies, as well as on 14 healthy controls. The association of strain echocardiographic variables with different grades of ACR was investigated. RESULTS: Of the 78 studies performed 4 ± 3 months after HT in 20 patients, 32 studies were coincident with grade 0R rejection, 41 with grade 1R, and 5 with grade 2R. Significantly lower values of average radial strain were found with higher grades of ACR (29.1 ± 7.7%, 23.2 ± 8.5%, and 14.3 ± 8.8% for grades 0R, 1R, and 2R of ACR, P = 0.001). Average deformation was similar for controls versus transplanted patients, in the absence of acute rejection: radial 29.1 ± 10.0% versus 29.1 ± 7.7%, P = 0.98; circumferential -19.3 ± 3.2% versus -20.2 ± 5.9%, P = 0.62; and longitudinal -20.7 ± 4.1% versus -18.5 ± 5.4%, P = 0.19. An average radial strain <25% presented 100% sensitivity, 48% specificity, 6% positive predictive value, and 100% negative predictive value for the presence of 2R rejection (area under the curve 0.80, IC 95% 0.60-0.99, P = 0.048). CONCLUSION: In this study, HT recipients showed significantly lower values of average radial left ventricle strain, evaluated by means of 2DSTE, with the presence of ACR.

RESUMEN

BACKGROUND: This study aimed to assess long-term prognosis of stable coronary artery disease (sCAD) in patients aged ≥ 75 years and to identify clinical predictors of cardiovascular and overall mortality. MATERIALS AND METHODS: From February 2000 to January 2007, 391 outpatients aged ≥ 75 years (median 78 years, interquartile range [IQR] 76-81 years, 66% male) with sCAD were recruited in this prospective cohort study. Associations of baseline variables with long-term cardiovascular and all-cause death were investigated. RESULTS: After up to 11 years of follow-up (median 4 years, IQR 2-6 years), 89 patients died (23%, 5·45%/year), 35 from cardiovascular causes (9%, 2·14%/year). Multivariate analysis identified family history of coronary disease (HR 4·28, 95% CI 1·22-15·02, P = 0·02), baseline atrial fibrillation (HR 3·18, 95% CI 1·37-7·39, P = 0·007), age (HR 1·61 per 5 year increase, 95% CI 1·04-2·50, P = 0·03), resting heart rate (HR 1·26 per 5 bpm increase, 95% CI 1·09-1·47, P = 0·003) and previous revascularization (HR 0·17, 95% CI 0·04-0·77, P = 0·02) as independent predictors of cardiovascular death, and previous acute coronary syndrome (HR 4·93, 95% CI 1·49-16·30, P = 0·009), baseline atrial fibrillation (HR 1·96, 95% CI 1·12-3·43, P = 0·02), tobacco use (HR 1·69, 95% CI 1·00-2·84, P = 0·049 for ex-smoking and HR 6·78, 95% CI 0·89-51·47, P = 0·06 for active smoking), age (HR 1·58 per 5 year increase, 95% CI 1·18-2·11, P = 0·002), resting heart rate (HR 1·10 per 5 bpm increase, 95% CI 1·00-1·22, P = 0·05) and diastolic blood pressure (HR 0·97, 95% CI 0·94-0·99, P = 0·01) as independent predictors of overall mortality. CONCLUSIONS: In this study, 4-years overall mortality was 23% among elderly patients with sCAD. Simple clinical variables can identify patients at higher risk of mortality.

RESUMEN

We sought to determine the incidence, risk factors, and consequences of acute rejection (AR) after conversion from a calcineurin inhibitor (CNI) to a proliferation signal inhibitor (PSI) in maintenance heart transplantation. Relevant clinical data were retrospectively obtained for 284 long-term heart transplant recipients from nine centers in whom CNIs were replaced with a PSI (sirolimus or everolimus) between October 2001 and March 2009. The rejection rate at one yr was 8.3%, stabilizing to 2% per year thereafter. The incidence rate after conversion (4.9 per 100 patient-years) was significantly higher than that observed on CNI therapy in the pre-conversion period (2.2 per 100 patient-years). By multivariate analysis, rejection risk was associated with a history of late AR prior to PSI conversion, early conversion (<5 yr) after transplantation and age <50 yr at the time of conversion. Use of mycophenolate mofetil was a protective factor. Post-conversion rejection did not significantly influence the evolution of left ventricular ejection fraction, renal function, or mortality during further follow-up. Conversion to a CNI-free immunosuppression based on a PSI results in an increased risk of AR. Awareness of the clinical determinants of post-conversion rejection could help to refine the current PSI conversion strategies.

RESUMEN

Biological differences between males and females change the course of different diseases and affect therapeutic measures' responses. Heart failure is not an exception to these differences. Women account for a minority of patients on the waiting list for heart transplantation or other advanced heart failure therapies. The reason for this under-representation is unknown. Men have a worse cardiovascular risk profile and suffer more often from ischemic heart disease. Conversely, transplanted women are younger and more frequently have non-ischemic cardiac disorders. Women's poorer survival on the waiting list for heart transplantation has been previously described, but this trend has been corrected in recent years. The use of ventricular assist devices in women is progressively increasing, with comparable results than in men. The indication rate for a heart transplant in women (number of women on the waiting list for millions of habitants) has remained unchanged over the past 25 years. Long-term results of heart transplants are equal for both men and women. We have analyzed the data of a national registry of heart transplant patients to look for possible future directions for a more in-depth study of sex differences in this area. We have analyzed 1-year outcomes of heart transplant recipients. We found similar results in men and women and no sex-related interactions with any of the factors related to survival or differences in death causes between men and women. We should keep trying to approach sex differences in prospective studies to confirm if they deserve a different approach, which is not supported by current evidence.

RESUMEN

The longer survival of patients with heart transplantation (HT) favors calcineurin inhibitor-related chronic kidney disease (CKD). It behoves to identify risk factors. At 14 Spanish centers, data on 1062 adult patients with HT (age 59.2 ± 12.3 yr, 82.5% men) were collected at routine follow-up examinations. Glomerular filtration rate, GFR, was estimated using the four-variable MDRD equation, and moderate-or-severe renal dysfunction (MSRD) was defined as K/DOQI stage 3 CKD or worse. Time since transplant ranged from one month to 22 yr (mean 6.7 yr). At assessment, 26.6% of patients were diabetic and 63.9% hypertensive; 53.9% were taking cyclosporine and 33.1% tacrolimus; and 61.4% had MSRD. Among patients on cyclosporine or tacrolimus at assessment, multivariate logistic regression identified male sex (OR 0.44), pre- and post-HT creatinine (2.73 and 3.13 per mg/dL), age at transplant (1.06 per yr), time since transplant (1.05 per yr), and tacrolimus (0.65) as independent positive or negative predictors of MSRD. It is concluded that female sex, pre- and one-month post-HT serum creatinine, age at transplant, time since transplant, and immunosuppression with cyclosporine rather than tacrolimus may all be risk factors for development of CKD ≥ stage 3 by patients with HT.

RESUMEN

Chronic kidney disease (CKD) is staged on the basis of glomerular filtration rate; generally, the MDRD study estimate, eGFR, is used. Renal dysfunction (RD) in heart transplant (HT) patients is often evaluated solely in terms of serum creatinine (SCr). In a cross-sectional, 14-center study of 1062 stable adult HT patients aged 59.1±12.5 yr (82.3% men), RD was graded as absent-or-mild (AoM), moderate, or severe (this last including dialysis and kidney graft) by two classifications: SCr-RD (SCr cutoffs 1.6 and 2.5 mg/dL) and eGFR-RD (eGFR cutoffs 60 and 30 mL/min/1.73 m2). SCr-RD was AoM in 68.5% of patients, moderate in 24.9%, and severe in 6.7%; eGFR-RD, AoM in 38.6%, moderate in 52.2%, severe in 9.2%. Among patients evaluated <2.7, 2.7-6.2, 6.2-9.5 and >9.5 yr post-HT (the periods defined by time-since-transplant quartiles), AoM/moderate/severe RD prevalences were <2.7, SCr-RD 74/21/5%, eGFR-RD 47/47/6%; 2.7-6.2, SCr-RD 73/22/5%, eGFR-RD 37/56/7%; 6.2-9.5, SCr-RD 69/24/7%, eGFR-RD 37/54/9%; >9.5, SCr-RD 58/32/10%, eGFR-RD 32/52/16%. The prevalence of severe RD increases with time since transplant. If the usual CKD stages are appropriate for HT patients, the need for less nephrotoxic immunosuppressants and other renoprotective measures is greater than is suggested by direct SCr-based grading, which should be abandoned as excessively insensitive.

RESUMEN

OBJECTIVES: CHADS(2) score predicts embolic risk in patients with nonvalvular atrial fibrillation (NVAF), but also bleeding risk in patients receiving oral anticoagulation (OAC). Our objective is to analyze the effectiveness and safety of OAC in patients with NVAF in daily clinical practice, according to embolic risk evaluated by means of CHADS(2) score. METHODS: All consecutive outpatients with permanent NVAF seen at 2 cardiology clinics were prospectively followed for embolic events (transient ischemic attack, ischemic stroke, peripheral embolism) and severe bleedings. OAC was prescribed according to the recommendations of scientific associations. CHADS(2) score was obtained for each patient. RESULTS: From February 1, 2000 to July 31, 2003, 796 outpatients fulfilled the inclusion criteria. OAC was prescribed to 564 (71%) patients. After 2.4 +/- 1.9 years of follow-up, the embolic event rates (per 100 patient-years) for each stratum of the CHADS(2 )score for patients with/without OAC were: 1/4.1, p = 0.23 (CHADS(2) = 0); 0.6/7.1, p = 0.0018 (CHADS(2) = 1); 0.5/5.1, p = 0.0014 (CHADS(2) = 2); 2.4/12.5, p = 0.0017 (CHADS(2) = 3) and 2.9/20, p = 0.013 (CHADS(2) >or=4). The severe bleeding rates for the same CHADS(2) score strata were 3/0.8, 0.8/0.7, 1.3/0.7, 0.4/0, and 2.9/5 in patients with/without OAC (n.s.). CONCLUSION: OAC is effective and safe in daily clinical practice in patients with NVAF and CHADS(2) score >or=1.

RESUMEN

BACKGROUND AND OBJECTIVES: Chronic heart failure continues to have a poor prognosis, in spite of advances made in its therapy. It is uncertain whether symptom-guided therapy optimization is the most effective strategy in this setting. The aim of our study was to evaluate the usefulness of a brain natriuretic peptide (BNP)-guided therapy for the treatment of patients with heart failure. PATIENTS AND METHODS: We carried out a prospective and randomized study including 60 patients consecutively discharged with the diagnosis of heart failure NYHA class III or IV in one cardiology department of a Spanish hospital; 30 patients were randomly assigned to a symptom-guided therapy group based on the clinical Framingham score, and 30 to a BNP-guided therapy group. Therapy was adjusted to obtain a clinical score <2 in the symptom-guided group and BNP levels <100pg/ml in the BNP-guided group. Follow up was 16±4 months. RESULTS: BNP-guided group had lower BNP levels during follow up than had symptom-guided group: 14(20)pg/ml versus 111±71pg/ml at 18 months, p=0.029. Clinical score was similar in both groups: 0.42(0.33) versus 0.39(0.63) at 18 months. Probability of survival (86% in both groups) and probability of being free of readmissions for heart failure (68 versus 66%) at 18 months were similar in both groups. CONCLUSIONS: In our experience, in patients with heart failure, BNP-guided therapy did not improve clinical outcomes compared with symptom-guided therapy.

RESUMEN

BACKGROUND: Lifelong adherence with post-transplant immunosuppression is challenging, with nonadherence associated with greater acute rejection (AR) risk. METHODS: This retrospective study evaluated conversion from immediate-release tacrolimus (IRT) to prolonged-release tacrolimus (PRT), between January 2008 and December 2012 in stable adult heart transplant recipients. Cumulative incidence rate (IR) of AR and infection pre- and postconversion, safety, tacrolimus dose and trough levels, concomitant immunosuppression, and PRT discontinuation were analyzed (intention-to-treat population). RESULTS: Overall, 467 patients (mean age, 59.3 [SD, 13.3] years) converted to PRT at 5.1 (SD, 4.9) years post transplant and were followed for 3.4 (SD, 1.5) years. During the 6 months post conversion, 5 patients (1.1%; 95% CI, 0.35%-2.48%) had an AR episode and IR was 2.2/100 patient-years (95% CI, 0.91-5.26). Incidence of rejection preconversion varied by time from transplant to conversion. Infection IR was similar post- and preconversion (9.2/100 patient-years [95% CI, 7.4-11.3] vs 10.6/100 patient-years [95% CI, 8.8-12.3], respectively; P = .20). Safety variables remained similar post conversion. The IR of mortality/graft loss was 2.3/100 patient-years (95% CI, 1.7-3.1). CONCLUSIONS: Conversion from IRT to PRT in heart transplant recipients in Spain was associated with no new safety concerns and appropriate immunosuppressive effectiveness.

RESUMEN

BACKGROUND: For cyclosporine (CsA), 2-hr postdose level (C2) is the best single time point predictor of the area under the curve and a critical measure for effective dosing. The therapeutic CsA microemulsion (Neoral) C2 range in de novo heart transplant patients remains to be determined. PURPOSE: The purpose of this study was to determine the efficacy of CsA C2 monitoring in de novo heart transplant patients receiving basiliximab induction. METHODS: This prospective, multicenter, randomized study enrolled 87 adult heart transplant recipients stratified according to 4 to 6 hrs posttransplant serum creatinine less than or equal to 170 micromol/L (cohort A) or more than 170 micromol/L (cohort B). Patients in cohort A were randomized into three C2 ranges (A1: "high" n=25, 1600-1800 ng/mL; A2: "intermediate" n=27, 1400-1600 ng/mL; and A3: "low" n=24, 1200-1400 ng/mL). Patients in cohort B were randomized into intermediate (n=5) and low C2 (n=6). Target ranges were progressively lowered after 1 month. Immunosuppression included basiliximab, Neoral, mycophenolate mofetil, and corticosteroids. Endpoints were acute rejection and renal function. RESULTS: The incidence of acute rejection at 12 months was 44% in group A1, 41% in group A2, 33% in group A3, and 27% in cohort B. Pretransplant and 12-month creatinine clearance (mL/min) were group A1, 72+/-25 and 64+/-24; group A2, 81+/-32 and 68+/-25; group A3, 91+/-28 and 86+/-26; and cohort B, 62+/-28 and 79+/-37. CONCLUSION: These results suggest that C2 monitoring is safe in de novo heart transplant patients. A low Neoral C2 range in combination with basiliximab induction resulted in preserved renal function without increased risk of acute rejection.

RESUMEN

Mycophenolic acid (MPA) dose reduction is associated with increased risk of rejection and graft loss in renal transplantation. This analysis investigated the impact of MPA dose changes with enteric-coated mycophenolate sodium (EC-MPS) or mycophenolate mofetil (MMF) in de novo heart transplant recipients. In a 12-month, single-blind trial, 154 patients (EC-MPS, 78; MMF, 76) were randomized to either EC-MPS (1080 mg bid) or MMF (1500 mg bid) in combination with cyclosporine and steroids. The primary efficacy variable was the incidence of treatment failure, comprising a composite of biopsy-proven (BPAR) and treated acute rejection, graft loss or death. Significantly fewer patients receiving EC-MPS required > or =2 dose reductions than patients on MMF (26.9% vs. 42.1% of patients, p = 0.048). Accordingly, the average daily dose of EC-MPS as a percentage of the recommended dose was significantly higher than for MMF (88.4% vs. 79.0%, p = 0.016). Among patients requiring > or =1 dose reduction, the incidence of treated BPAR grade > or =3A was significantly lower with EC-MPS compared with MMF (23.4% vs. 44.0%, p = 0.032). These data suggest that EC-MPS-treated heart transplant patients are less likely to require multiple dose reductions than those on MMF which may be associated with a significantly lower risk of treated BPAR > or =3A.

RESUMEN

BACKGROUND: Cytomegalovirus (CMV) infection in recipients of cardiac transplants is associated with higher rates of morbidity. A recent phase III trial showed highly significantly (P<0.001) lower CMV rates with the proliferation signal inhibitor everolimus compared to azathioprine (AZA). To better define this association, data on CMV risk factors were collected retrospectively and analyzed. METHODS: Data on CMV risk factors from a multicenter phase III trial on de novo heart transplant recipients (n=634) receiving a triple immunosuppressive regimen randomized to everolimus 1.5 mg/day (group 1), everolimus 3 mg/day (group 2), or AZA (group 3) were merged with prospectively collected CMV-related outcome data and analyzed. RESULTS: CMV-positive donors (D+) and CMV-negative recipients (R-) were evenly distributed across groups 1-3 at 36/209 (17.2%), 48/211 (22.7%), and 38/214 (17.8%), respectively. CMV prophylaxis had been given for a mean (SD) of 175 (127.8), 183 (137.1), and 177 (132.9) days, respectively. In the high-risk D+/R- subgroup with prophylaxis, the proportions of patients with CMV infection compared with group 3 (12/29 [41.4%]) were 3/25 (12.0%) in group 1 (P=0.031) and 6/36 (16.7%) in group 2 (P=0.049). In D+/R+ subgroups either with or without prophylaxis, the everolimus groups had less CMV disease (P<0.001). The incidence of CMV syndrome, organ involvement, and laboratory evidence was lower with everolimus use compared to AZA. CONCLUSIONS: Everolimus is associated with lower rates of CMV infection, syndrome, or organ involvement, suggesting an additional advantage from the use of everolimus in cardiac transplant recipients.

RESUMEN

INTRODUCTION AND OBJECTIVES: Heart failure with preserved systolic function accounts for almost 40% of heart failure cases. Prognosis is similar to that in patients with a low left ventricular ejection fraction (LVEF). However, it is not clear whether the etiology of heart failure with preserved systolic function has an effect on prognosis. METHODS: We assessed 95 consecutive patients admitted to our hospital with heart failure and a LVEF>45%. Twenty-five (26%) had an ischemic etiology and 70 (74%), a non-ischemic etiology. RESULT: The patients' mean age was 73 (6) years, 60% were female, and their mean LVEF was 61 (7)%. These characteristics were similar in the two etiological groups. After a mean follow-up period of 53 (8) months (4-69 months; median 46 months), mortality was higher in ischemic patients (17.88 vs 2.37/100 patient-years; P<.0001), as was the rate of cardiovascular admissions (24.58 vs 4.14/100 patient-years; P<.0001). The rates of mortality due to heart failure and sudden death were also higher in ischemic patients, at 7.82 vs 0.59/100 patient-years, and 7.82 vs 0.30/100 patient-years, respectively (P<.0001). The higher overall admission rate found in the ischemic group was due to higher rates of admission for heart failure (14.53 vs 0.89/100 patient-years; P<.0001) and acute coronary syndrome (8.94 vs 1.78/100 patient-years; P=.003). CONCLUSIONS: In terms of prognosis, heart failure with preserved systolic function is not a homogeneous disease entity. Morbidity and mortality rates are higher in patients with an ischemic etiology. Moreover, different mechanisms are involved.

RESUMEN

INTRODUCTION AND OBJECTIVES: The present article reports the characteristics and results of heart transplants in Spain since this therapeutic modality was first used in May 1984. METHODS: We describe the main features of recipients, donors, surgical procedures, and results of all heart transplants performed in Spain until December 31, 2015. RESULTS: A total of 299 cardiac transplants were performed in 2015, with the whole series comprising 7588 procedures. The main transplant features in 2015 were similar to those observed in recent years. A remarkably high percentage of transplants were performed under emergency conditions and there was widespread use of circulatory assist devices, particularly continuous-flow left ventricular assist devices prior to transplant (16% of all transplants). Survival has significantly improved in the last decade compared with previous time periods. CONCLUSIONS: During the last few years, between 250 and 300 heart transplants have consistently been performed each year in Spain. Despite a more complex clinical context, survival has increased in recent years.

RESUMEN

BACKGROUND AND AIM OF THE STUDY: Perivalvular abscess is a serious complication in infective endocarditis (IE) that confers a poor prognosis. Few data are available concerning the long-term outcome of these patients. The study aim was to determine clinical features and long-term prognosis of non-drug addict patients with IE complicated by perivalvular abscess. METHODS: Among a consecutive series of 241 patients with IE, 30 (12.4%) were diagnosed with perivalvular abscess and treated at the authors' institution over a 15-year period. A comparative analysis of patients with perivalvular abscess and other patients in the series was performed. RESULTS: Perivalvular abscess was more frequently associated with aortic valve endocarditis (93% versus 35%, p <0.05), and Streptococcus sp. was the predominant microorganism. Severe complications during hospital admission were more common in patients with perivalvular abscess (100% versus 61%, p <0.01). In-hospital mortality was significantly higher in patients with perivalvular abscess (33% versus 15%, p <0.05). Event-free survival at five years among survivors of the in-hospital phase was 86% in patients with perivalvular abscess, and 83% in those without abscess (p = NS). CONCLUSION: Patients with IE and perivalvular abscess have a higher in-hospital mortality rate, as major complications are more common in these patients. However, among patients who survived the active phase of the disease, long-term survival was similar with or without perivalvular abscess.

RESUMEN

INTRODUCTION AND OBJECTIVES: We present the characteristics and outcomes of heart transplantation in Spain since it was first performed in 1984. METHODS: A descriptive analysis of the characteristics of recipients, donors, the surgical procedure, and the outcomes of heart transplantations performed in Spain until 31 December 2014. RESULTS: In 2014, 266 procedures were performed, making a time series of 7289 transplantations. The temporal analysis confirmed a significant worsening of the clinical profile of recipients (higher percentage of older patients, patients with severe renal failure, insulin-dependent diabetes, previous cardiac surgery, and previous mechanical ventilation), of donors (higher percentage of older donors and greater weight mismatch), and of the procedure (higher percentage of emergency transplantations, reaching 41.4% in 2014, and ischemia time>240min). Mechanical assist devices were used less than in 2013; in 2014 they were used in 18.8% of all transplant recipients. Survival at 1, 5, 10, and 15 years was 76%, 65%, 52%, and 38%, respectively, and has remained stable since 1995. CONCLUSIONS: Cardiac transplantation activity in Spain has remained stable in recent years, at around 250 procedures per year. Despite a clear deterioration in donor and recipient characteristics and surgical times, the mortality outcomes have remained comparable to those of previous periods in our environment. The growing use of circulatory assist devices before transplantation is also confirmed.
