RESUMEN

Introduction and objectives: Mitochondrial pyruvate carrier (MPC) mediates the entry of pyruvate into mitochondria, determining whether pyruvate is incorporated into the Krebs cycle or metabolized in the cytosol. In heart failure (HF), a large amount of pyruvate is metabolized to lactate in the cytosol rather than being oxidized inside the mitochondria. Thus, MPC activity or expression might play a key role in the fate of pyruvate during HF. The purpose of this work was to study the levels of the two subunits of this carrier, named MPC1 and MPC2, in human hearts with HF of different etiologies. Methods: Protein and mRNA expression analyses were conducted in cardiac tissues from three donor groups: patients with HF with reduced ejection fraction (HFrEF) with ischemic cardiomyopathy (ICM) or idiopathic dilated cardiomyopathy (IDC), and donors without cardiac pathology (Control). MPC2 plasma levels were determined by ELISA. Results: Significant reductions in the levels of MPC1, MPC2, and Sirtuin 3 (SIRT3) were observed in ICM patients compared with the levels in the Control group. However, no statistically significant differences were revealed in the analysis of MPC1 and MPC2 gene expression among the groups. Interestingly, Pyruvate dehydrogenase complex (PDH) subunits expression were increased in the ICM patients. In the case of IDC patients, a significant decrease in MPC1 was observed only when compared with the Control group. Notably, plasma MPC2 levels were found to be elevated in both disease groups compared with that in the Control group. Conclusion: Decreases in MPC1 and/or MPC2 levels were detected in the cardiac tissues of HFrEF patients, with ischemic or idiopatic origen, indicating a potential reduction in mitochondrial pyruvate uptake in the heart, which could be linked to unfavorable clinical features.

RESUMEN

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.

RESUMEN

BACKGROUND: Tricuspid regurgitation (TR) after heart transplant (HT) can be an important complication depending on its etiology and severity. This study aims to analyze the prevalence of TR, the causes, and its evolution over time after HT. METHODS: We performed a retrospective study of transplants performed between 2000 and 2019 in 2 centers (1009 patients). TR was grouped according to etiology: primary graft dysfunction (PGD), acute rejection, cardiac allograft vasculopathy (CAV), pulmonary hypertension, prolapse, endomyocardial biopsy complication (EMB), pacemaker (PM), and unclear etiology (TR not related to any process and for which no justification was found). RESULTS: The prevalence of TR after HT was 19.8% (moderate: 13.2%, severe: 6.6%). Significant TR was more prevalent in the first months (month 1: 51%, month 3: 40%, month 6: 29%, 1 year: 24%). These results were related to the etiologies. Thus, in the first month, TR due to PGD is frequent and it is the only time when TR due to pulmonary hypertension appears. During the first 6 months, TR of unclear cause gains relevance, which tends to decrease over time. After 1 year, TR due to rejection predominates. After 5 years, TR is less frequent (< 10%) and related to long-term complications of HT, such as CAV, EMB, and those associated with PM. CONCLUSIONS: The prevalence of TR after HT is 19.8%. Prevalence and etiology change over time. Initially it is usually related to PGD, in the medium-term to rejection and in the long-term to CAV and procedures such as EMB and PM.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Background: Infection is a major cause of morbidity and mortality after heart transplantation (HT). Little information about its importance in the immediate post-operative period is available. The aim of this study was to analyze the characteristics, incidence, and outcomes of in-hospital post-operative infections after HT. Methods: We conducted an observational, single-center study based on 677 adults who underwent HT from 1991 to 2015 and who survived the surgical intervention. In-hospital post-operative infections were identified retrospectively according to the medical finding in the clinical records. Results: Over a mean hospital stay of 24.5 days, 239 patients (35.3%) developed 348 episodes of infection (2 episodes per 100 patient-days). The most common sources of infection were those related to invasive procedures (respiratory infections, 115 [33%]; urinary tract infections, 47 [13.5%]; bacteremia, 42 [12.1%]; surgical site infections, 25 [7.2%]), in addition to abdominal focus (33, 9.5%). Enterobacteriaceae (76, 21.8%) and gram-positive cocci (58, 16.7%) were the predominant germs, although opportunistic infections were not infrequent (69, 19.8%). Ninety-five septic episodes were detected with a mean Sequential Organ Failure Assessment Score of 9.5 ± 5.3 points, with hemodynamic failure being the most severe organ dysfunction and renal dysfunction the most frequent one. Management included broad-spectrum antibiotics in 48.8% of episodes and surgical management in 13.8%. The overall antimicrobial success rate was 96.3%. Higher in-hospital mortality was observed among infected patients (15.1% vs. 10.3%), but this difference was not statistically significant (p = 0.067). The one-year survival and events were not different between patients suffering from a post-operative infection and those who did not. Conclusions: In-hospital infections were frequent in the post-operative period after HT and were associated with a poor short-term outcome. Patients who survived sepsis had a similar one-year morbidity and mortality compared with patients who did not develop an infection.

RESUMEN

INTRODUCTION: Infection is one of the most significant complications following heart transplantation (HT). The aim of this study was to identify specific risk factors for early postoperative infections in HT recipients, and to develop a multivariable predictive model to identify HT recipients at high risk. METHODS: A single-center, observational, and retrospective study was conducted. The dependent variable was in-hospital postoperative infection. We examined demographic and epidemiological data from donors and recipients, surgical features, and adverse postoperative events as independent variables. Backwards, stepwise multivariable logistic regression with a P-value < 0.05 was used to identify clinical factors independently associated with the risk of in-hospital postoperative infections following HT. RESULTS: Six hundred seventy-seven patients were included in this study. During the in-hospital postoperative period, 348 episodes of infection were diagnosed in 239 (35.9%) patients. Seven variables were identified as independent clinical predictors of early postoperative infection after HT: history of diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and use of itraconazole. Based on the results of multivariable models, we constructed a 7-variable (8-point) score to predict the risk of in-hospital postoperative infection in HT recipients, which showed a reasonable ability to predict the risk of in-hospital postoperative infection in this population. Prospective external validation of this new score is warranted to confirm its clinical applicability. CONCLUSIONS: In-hospital postoperative infection is a common complication after HT, affecting 35% of patients who underwent this procedure at our institution. Diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and itraconazole were all independent clinical predictors of early postoperative infection after HT.

RESUMEN

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.

RESUMEN

AIM: To analyse the incidence, risk factors and clinical outcomes of late graft failure after heart transplantation. METHODS AND RESULTS: We conducted an observational, single-centre study based on 547 patients who underwent cardiac transplantation from 1991 to 2014 and who survived the in-hospital postoperative period. Late graft failure was defined as the first hospitalization due to this condition after discharge. Over a mean follow-up of 8.4 ± 6 years, 178 (32.5%) patients were hospitalized due to late graft failure [incidence rate: 3.6 cases per 100 patient-years, 95% confidence interval (CI) 3.1-4.2]. Pre-transplant diabetes, higher pre-transplant transpulmonary pressure gradient and lower donor-recipient weight ratio were independently associated with higher risk of graft failure. Cardiac allograft vasculopathy, cellular rejection grade ≥1R, and antibody-mediated rejection grade ≥1 were detected in 50.6%, 44.9% and 19.2% patients, respectively, admitted due to graft failure. Left ventricular ejection fraction was ≥50% in 60.1% of these patients. Re-transplant free survival 1, 5, 10 and 15 years after the diagnosis of late graft failure was 72.2%, 38.4%, 18.4%, and 7.5%, respectively; the incidence rate of re-hospitalization due to decompensated heart failure was 40.9 episodes per 100 patient-years (95% CI 36.6-46.1). The need for inotropes, the presence of cardiac allograft vasculopathy, higher creatinine serum levels, lower ejection fraction and lower sodium serum levels were independent predictors of worse outcomes. CONCLUSIONS: Late graft failure is frequent after heart transplantation, as it is associated with poor outcomes. Rejection and cardiac allograft vasculopathy are the most frequent underlying causes.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIMS: The 'obesity paradox' is consistently observed in patients with heart failure (HF). We investigated the relationship of body surface area (BSA) to mortality and hospitalizations in patients with chronic HF. METHODS AND RESULTS: Data from the outpatient cohort of the observational, prospective, Heart Failure Long-Term Registry of the Heart Failure Association of the European Society of Cardiology was analysed in order to evaluate the prognostic significance of BSA in chronic HF. A total of 9104 chronic HF patients (age 64.8 ± 13.4 years; 71.6% males) were enrolled. Mortality during 1-year follow-up was observed in 718 of 8875 (8.1%) patients. A progressive, inverse relationship between all-cause mortality and BSA levels was observed; the adjusted hazard ratio (HR) for 1-year mortality was 1.823 [95% confidence interval (CI) 1.398-2.376], P < 0.001 for the lowest quartile of BSA <1.78 m(2) , and 1.255, 95% CI 1.000-1.576, P = 0.05 for the middle two quartiles (1.78 ≤BSA ≤2.07 m(2) ), compared with the highest quartile (BSA >2.07 m(2) ). For each increase of 0.1 m(2) in BSA, an adjusted HR of 0.908 (95% CI 0.870-0.948), P < 0.001 for mortality was calculated. HF hospitalizations were not associated with BSA subgroup distribution. In both genders, subjects within the lowest BSA quartile (males <1.84 m(2) and females <1.64 m(2) ) had significantly higher mortality rates during follow-up (log-rank P < 0.0001). However, the stepwise association with mortality was more distinct in males. CONCLUSIONS: Total and cardiovascular mortality, but not HF hospitalizations was inversely associated with BSA levels in chronic HF patients. BSA may serve as a prognostic indicator for adverse outcome in HF patients.

RESUMEN

We conducted an observational study of 30 heart transplant recipients with serum low-density lipoprotein cholesterol (LDL-c) >100 mg/dl despite previous statin therapy, who were treated with rosuvastatin 10 mg daily (5 mg in case of renal dysfunction). Serum lipids, creatine phosphokinase (CPK), bilirubin, and hepatic enzymes were prospectively measured 2, 4, and 12 weeks after the initiation of the drug. Clinical outcomes of patients who continued on long-term rosuvastatin therapy beyond this 12-week period were reviewed in February 2015. Over the 12-week period following rosuvastatin initiation, serum levels of total cholesterol (TC) and LDL-c and the ratio TC/high-density lipoprotein cholesterol (HDL-c) decreased steadily (P < 0.001). Average absolute reductions of these three parameters were -48.7 mg/dl, -46.6 mg/dl, and -0.9, respectively. Seventeen (57%) achieved a serum LDL-c < 100 mg/dl. No significant changes from baseline were observed in serum levels of triglycerides, HDL-c, hepatic enzymes, bilirubin, or CPK. Twenty-seven (90%) patients continued on long-term therapy with rosuvastatin over a median period of 3.6 years, with no further significant variation in lipid profile. The drug was suspended due to liver toxicity in 1 (3.3%) patient and due to muscle toxicity in 2 (6.7%) patients. All adverse reactions resolved rapidly after rosuvastatin withdrawal. Our study supports rosuvastatin as a reasonable alternative for heart transplant recipients with hypercholesterolemia and therapeutic failure of other statin regimens.
