RESUMEN

BACKGROUND: Dilated cardiomyopathy (DCM) associated with inflammation is diagnosed by endomyocardial biopsy; patients with this have a poorer prognosis than patients without inflammation. To date, standard diagnostic criteria have not been established.Methods and Results: This study analyzed clinical records and endomyocardial biopsy samples of 261 patients with DCM (201 males, median left ventricular ejection fraction; 28%) from 8 institutions in a multicenter retrospective study. Based on the European Society of Cardiology criteria and CD3 (T-lymphocytes) and CD68 (macrophages) immunohistochemistry, 48% of patients were categorized as having inflammatory DCM. For risk-stratification, we divided patients into 3 groups using Akaike Information Criterion/log-rank tests, which can determine multiple cut-off points: CD3+-Low, <13/mm2(n=178, 68%); CD3+-Moderate, 13-24/mm2(n=58, 22%); and CD3+-High, ≥24/mm2(n=25, 10%). The survival curves for cardiac death or left ventricular assist device implantation differed significantly among the 3 groups (10-year survival rates: CD3+-Low: 83.4%; CD3+-Moderate: 68.4%; CD3+-High: 21.1%; Log-rank P<0.001). Multivariate Cox analysis revealed CD3+count as a potent independent predictive factor for survival (fully adjusted hazard ratio: CD3+-High: 5.70, P<0.001; CD3+-Moderate: 2.64, P<0.01). CD3+-High was also associated with poor left ventricular functional and morphological recovery at short-term follow up. CONCLUSIONS: Myocardial CD3+T-lymphocyte infiltration has a significant prognostic impact in DCM and a 3-tiered risk-stratification model could be helpful to refine patient categorization.

RESUMEN

BACKGROUND: Palliative care is highly relevant for patients with heart failure (HF), and there is a need for quantitative information on quality of care. Accordingly, this study aimed to develop a set of quality indicators (QIs) for palliative care of HF patients, and to conduct a practical pilot measurement of the proposed QIs in clinical practice.Methods and Results:We used a modified Delphi technique, a consensus method that involves a comprehensive literature review, face-to-face multidisciplinary panel meeting, and anonymous rating in 2 rounds. A 15-member multidisciplinary expert panel individually rated each potential indicator on a scale of 1 (lowest) to 9 (highest) for appropriateness. All indicators receiving a median score ≥7 without significant disagreement were included in the final set of QIs. Through the consensus-building process, 35 QIs were proposed for palliative care in HF patients. Practical measurement in HF patients (n=131) from 3 teaching hospitals revealed that all of the proposed QIs could be obtained retrospectively from medical records, and the following QIs had low performance (<10%): "Intervention by multidisciplinary team", "Opioid therapy for patients with refractory dyspnea", and "Screening for psychological symptoms". CONCLUSIONS: The first set of QIs for palliative care of HF patients was developed and could clarify quantitative information and might improve the quality of care.

RESUMEN

BACKGROUND: Little is known about palliative sedation in terminally ill heart failure (HF) patients.Methods and Results:We retrospectively reviewed terminally ill HF patients who received palliative sedation from September 2013 to August 2018. Among 95 terminally ill HF patients, 25 were prescribed dexmedetomidine and 12 were prescribed midazolam at the end of life. Richmond Agitation-Sedation Scale was significantly reduced (P<0.01), but blood pressure and heart rate were unaltered after treatment in both the dexmedetomidine and midazolam groups. CONCLUSIONS: Prescription of dexmedetomidine and/or midazolam might be feasible in selected terminally ill HF patients.

RESUMEN

BACKGROUND: The ideal mortality prediction model (MPM) for acute heart failure (AHF) patients would have sufficient and stable predictive ability for long-term as well as short-term mortality. However, published MPMs for AHF predominantly predict short-term mortality up to 90 days, and their prognostic performance for long-term mortality remains unclear. Methods and Results: We analyzed 609 AHF patients in a prospective registry from January 2013 to May 2016. We compared the prognostic performance for long-term mortality among 8 systematically identified MPMs for AHF that predict short-term mortality up to 90 days from admission. The PROTECT 7-day model showed the highest c-index for long-term as well as short-term mortality among the studied MPMs. Sensitivity analyses revealed serum albumin and total cholesterol to be the most important variables, as dropping these variables resulted in a significant decline in c-index, when compared with other variables specific to the PROTECT 7-day model. Furthermore, significant improvements in c-index and net reclassification were observed when serum albumin or serum albumin plus total cholesterol was added to the studied MPMs, other than the PROTECT 7-day model. CONCLUSIONS: The PROTECT 7-day model demonstrated the highest predictive performance for long-term as well as short-term mortality in AHF patients among the published MPMs. Our findings indicate the importance of accounting for nutritional status such as serum albumin and total cholesterol in AHF patients when developing a MPM.

RESUMEN

Palliative care for end-stage heart failure should be provided by a multidisciplinary team. However, the influence of each occupational category on patients receiving palliative care for end-stage heart failure remains unclear. Thus, this study investigated the relationships between palliative care conferences and positive outcomes of palliative care for end-stage heart failure patients. We sent questionnaires to all cardiology training hospitals authorized by the Japanese Circulation Society (n = 1004); of these, responses from the directors at 554 institutions were analyzed. We divided the responding institutions into two groups according to their implementation of palliative care conferences for patients with end-stage heart failure. The institutions that had held such conferences (n = 223) had a larger number of hospital beds, beds in the cardiovascular department, and patients admitted to the cardiovascular department, compared with institutions that had not held these conferences (n = 321). The usage rates of opioids, non-steroidal anti-inflammatory drugs, and sedatives were significantly higher in institutions that held these conferences. Multivariate analysis revealed that nutritionists and medical social workers had greater involvement in the improvement of mental symptoms and ensuring that patients could stay where they wished, respectively. The presence of palliative care physicians, physical therapists, or pharmacists was associated with multiple positive outcomes. This study indicated that there are possible associations between palliative care conferences and positive outcomes when performing palliative care for patients with end-stage heart failure.

RESUMEN

The diffusing capacity of the lung for carbon monoxide (DLCO) is indicative of the alveolar-capillary membrane function. A reduced DLCO is associated with poor prognosis in chronic heart failure (HF). However, the significance of DLCO as an independent prognostic predictor has not been established. Here, we aimed to determine the prognostic value of DLCO in patients with chronic HF.We enrolled 214 patients (139 females, mean age: 63 ± 16 years, left ventricular ejection fraction [LVEF]: 45 ± 21%) with stable chronic HF who underwent pulmonary function tests. Only never smokers were included in the analysis because smoking can decrease DLCO.During a median follow-up period of 2.1 years, 52 patients (24.3%) experienced cardiac events, including unplanned HF admissions, left ventricular assist device (LVAD) implantations, all-cause deaths, and cardiopulmonary arrests (CPAs). The median percent predicted DLCO (%DLCO) was 87.3%. In a Cox regression analysis, a %DLCO of ≤87.3% was independently associated with the cardiac events, even after adjusting for age, sex, systolic blood pressure (SBP), LVEF, anemia, brain natriuretic peptide, estimated glomerular filtration rate (eGFR), and prior HF admission (hazard ratio [HR]: 1.87, 95% confidence interval: 1.03-3.53, P = 0.030).A reduced DLCO is an independent predictor of poor prognosis in nonsmoking patients with chronic HF.

RESUMEN

BACKGROUND AND PURPOSE: The incidence of heart failure increases the subsequent risk of ischemic stroke, and its risk could be higher in the short-term period after an acute heart failure (AHF) event. However, its determinants remain to be clarified. Plasma D-dimer level reflects fibrin turnover and exhibits unique properties as a biomarker of thrombosis. The aim of this study is to investigate whether D-dimer level is a determinant of short-term incidence of ischemic stroke in patients with AHF. METHODS: We examined 721 consecutive hospitalized AHF patients with plasma D-dimer level on admission from our prospective registry between January 2013 and May 2016. The study end points were incidence of ischemic stroke during hospitalization and at 30 days after admission. RESULTS: Of the total participants (mean age, 76 years; male, 60%; atrial fibrillation, 54%; mean left ventricular ejection fraction, 38%), in-hospital ischemic stroke occurred in 18 patients (2.5%) during a median hospitalization period of 21 days, and 30-day ischemic stroke occurred in 16 patients (2.2%). Higher D-dimer level on admission was an independent determinant of subsequent risk of in-hospital ischemic stroke even after adjustment by CHA2DS2-VASc score (odds ratio, 2.29; 95% confidence interval, 1.46-3.60; P<0.001) or major confounders, including age, atrial fibrillation, and antithrombotic therapy (odds ratio, 2.31; 95% confidence interval, 1.43-3.74; P<0.001). Subgroup analyses showed consistent findings in patients without atrial fibrillation (odds ratio, 2.46; 95% confidence interval, 1.39-4.54; P=0.002) and those without antithrombotic therapy (odds ratio, 2.79; 95% confidence interval, 1.53-5.57; P<0.001). Similar results were obtained for 30-day ischemic stroke as an alternative outcome. CONCLUSIONS: Elevated plasma D-dimer level on admission was significantly associated with increased incidence of ischemic stroke shortly after admission for AHF, suggesting a predictive role of D-dimer for short-term ischemic stroke events in patients with AHF.

RESUMEN

BACKGROUND: Palliative care for heart failure (HF) patients is recommended in Western guidelines, so this study aimed to clarify the current status of palliative care for HF patients in Japan.Methods and Results:A survey was sent to all Japanese Circulation Society-authorized cardiology training hospitals (n=1,004) in August 2016. A total of 544 institutions (54%) returned the questionnaire. Of them, 527 (98%) answered that palliative care is necessary for patients with HF. A total of 227 (42%) institutions held a palliative care conference for patients with HF, and 79% of the institutions had <10 cases per year. Drug therapy as palliative care was administered at 403 (76%) institutions; morphine (87%) was most frequently used. Among sedatives, dexmedetomidine (33%) was administered more often than midazolam (29%) or propofol (20%). Regarding the timing of end-of-life care, most institutions (84%) reported having considered palliative care when a patient reached the terminal stage of HF. Most frequently, the reason for the decision at the terminal stage was "difficulty in discontinuing cardiotonics." A major impediment to the delivery of palliative care was "difficulty predicting an accurate prognosis." CONCLUSIONS: This large-scale survey showed the characteristics of palliative care for HF in Japan. The present findings may aid in the development of effective end-of-life care systems.

RESUMEN

BACKGROUND: Serum Wisteria floribunda agglutinin positive Mac-2 binding protein (WFA+-M2BP) or Mac-2 Binding Protein Glycosylation Isomer (M2BPGi) is a novel biomarker currently applied for evaluating hepatic fibrosis. The aim of this study was to evaluate the utility of serum WFA+-M2BP level as a biomarker in chronic heart failure (HF) patients with abnormal liver function. METHODS AND RESULTS: Fifty chronic HF patients who underwent measurement of serum WFA+-M2BP were evaluated. The median value of serum WFA+-M2BP was 0.88 (interquartile range 0.48-1.29) cut-off index, and positive WFA+-M2BP (≥ 1.00 cut-off index) was observed in 22 (44%). Elevated WFA + -M2BP was associated with longer HF history, older age, female sex, valvular heart disease, decreased estimated glomerular filtration rate (eGFR), albumin, and cholinesterase. Stepwise multiple regression analysis showed that HF history, eGFR, and albumin were independent determinants of serum WFA+-M2BP values. Repeated measurements of serum WFA+-M2BP suggested association between the decrease of WFA+-M2BP and improvement of New York Heart Association (NYHA) functional class. CONCLUSIONS: Elevation of serum WFA+-M2BP showed a high prevalence in chronic HF patients with abnormal liver function with relation to HF history, decreased hepatic protein synthesis, and renal dysfunction. Our results suggest that serum WFA+-M2BP may be a novel biomarker of chronic HF.

RESUMEN

BACKGROUND: Surgical treatment of functional mitral regurgitation (FMR) improves ventricular remodeling in patients with dilated cardiomyopathy (DCM). However, it is unclear whether surgical treatment improves long-term outcomes. We investigated the effects of mitral valve (MV) surgery in patients with DCM and FMR.Methods and Results:Of 525 patients with DCM hospitalized due to heart failure between January 1996 and September 2014, 70 who had severe FMR despite receiving optimal medical therapy were enrolled in the study. Of these patients, 16 underwent surgery for FMR (surgery group; repair=14, replacement=2); the remaining 54 who refused or decided not to undergo surgery were classified as the medication group. There were no differences in age, sex, medication, or echocardiographic parameters between the 2 groups (P>0.05). During the mean follow-up period of 53.6±43.6 months, the occurrence of clinical outcomes (i.e., all-cause death or left ventricular assist device implantation) was 54.3%; the occurrence of clinical outcomes was lower in the surgery group (P=0.008, log-rank test). Multivariate Cox regression analysis using clinical data revealed that MV surgery (hazard ratio [HR] 0.257, 95% confidence interval [CI] 0.103-0.640; P=0.004) and diabetes mellitus (HR 2.924, 95% CI 1.243-6.876; P=0.014) were independent predictors of clinical outcomes after adjusting for age and sex. CONCLUSIONS: Surgery for severe FMR provides better long-term outcomes in patients with DCM.

RESUMEN

BACKGROUND: The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted over a prosthetic valve, has been shown to be safe and therapeutically effective, depending on the size of the replacement valve.Methods and Results:We report 3 cases of successful valve-in-valve procedure to replace a degenerated 19-mm stented prosthetic aortic valve. Balloon-expanding THVs were implanted: 20-mm in the 1st case and 23-mm in the next 2. Aortic stenosis was almost completely resolved in all patients, who recovered promptly and without cardiac adverse events. CONCLUSIONS: Using the valve-in-valve procedure for a 19-mm degenerated bioprosthesis was feasible and safe.

RESUMEN

BACKGROUNDS: Despite current therapies, acute heart failure (AHF) remains a major public health burden with high rates of in-hospital and post-discharge morbidity and mortality. Carperitide is a recombinantly produced intravenous formulation of human atrial natriuretic peptide that promotes vasodilation with increased salt and water excretion, which leads to reduction of cardiac filling pressures. A previous open-label randomized controlled study showed that carperitide improved long-term cardiovascular mortality and heart failure (HF) hospitalization for patients with AHF, when adding to standard therapy. However, the study was underpowered to detect a difference in mortality because of the small sample size. METHODS: Low-dose Administration of Carperitide for Acute Heart Failure (LASCAR-AHF) is a multicenter, randomized, open-label, controlled study designed to evaluate the efficacy of intravenous carperitide in hospitalized patients with AHF. Patients hospitalized for AHF will be randomly assigned to receive either intravenous carperitide (0.02 µg/kg/min) in addition to standard treatment or matching standard treatment for 72 h. The primary end point is death or rehospitalization for HF within 2 years. A total of 260 patients will be enrolled between 2013 and 2018. CONCLUSION: The design of LASCAR-AHF will provide data of whether carperitide reduces the risk of mortality and rehospitalization for HF in selected patients with AHF.

RESUMEN

BACKGROUND: Functional mitral regurgitation (FMR) is a common complication of heart failure (HF) and worsens in acute decompensation. It is unclear whether FMR on admission or discharge determines the outcome. This study aimed to elucidate the prognostic significance of FMR on admission or discharge in patients admitted with acute decompensated HF. METHODS AND RESULTS: From 2006 to 2009, 349 patients admitted with acute decompensated HF were enrolled. They were followed with the composite endpoint of all-cause death and hospitalization for HF; 74 (21%) died and 113 (32%) developed the composite endpoint during 2.1±1.3 years. Moderate/severe FMR at discharge was associated with the composite endpoint (P=0.001), whereas that on admission was not. Multivariate Cox proportional hazard analysis showed that moderate/severe FMR (hazard ratio [95% confidence interval] =1.70 [1.03-2.73] P=0.04), logBNP, and NYHA class III/IV at discharge were independent determinants of the outcome. Moderate/severe FMR at discharge with BNP ≥200 pg/ml was prognostic, but BNP <200 pg/ml was no longer prognostic. CONCLUSIONS: Residual moderate/severe FMR after medical therapy for acute decompensated HF was associated with poor outcome, suggesting a potential target for further treatment of HF.

RESUMEN

BACKGROUND: There are limited studies regarding the prognostic value of coagulation abnormalities in heart failure patients. The clinical significance of prothrombin time international normalized ratio (INR), a widely accepted marker assessing coagulation abnormalities, in acute decompensated heart failure (ADHF) remains unclear. METHODS AND RESULTS: Among 561 consecutive patients admitted for ADHF, INR was assessed in 294 patients without prior anticoagulation therapy, acute coronary syndrome, liver disease, or overt disseminated intravascular coagulation. Increased INR on admission was positively associated with increased levels of thrombin-antithrombin complex, C-reactive protein, total bilirubin, γ-glutamyl transpeptidase, inferior vena cava diameter, tricuspid regurgitation severity, markers of neurohormonal activation, and also negatively associated with decreased albumin, cholinesterase, and total cholesterol. In contrast, there was no significant association with left ventricular ejection fraction, serum sodium or blood urea nitrogen. Multivariate analysis showed that increased INR was independently associated with increased all-cause mortality (hazard ratio 1.89 per 0.1 increase, 95% confidence interval 1.14-3.13, P=0.013) during the median follow up of 284 days. Increased INR also had a higher prognostic value compared to risk score models including the Model for End-Stage Liver Disease (MELD) score or the MELD excluding INR (MELD-XI) score. CONCLUSIONS: Increased INR is an independent predictor of all-cause mortality in ADHF patients without anticoagulation, reflecting coagulation abnormalities and hepatic insufficiency, possibly through systemic inflammation, neurohormonal activation and venous congestion.

RESUMEN

BACKGROUND: We hypothesized that exhaled acetone concentration (EAC), reflecting altered blood ketone body metabolism and increased acetone exhaust because of pulmonary congestion in heart failure (HF), would correlate with hemodynamic parameters in patients with non-ischemic chronic HF. METHODS AND RESULTS: We prospectively enrolled 102 non-ischemic HF patients with New York Heart Association (NYHA) class I-III. Exhaled breath was collected after an overnight fast. Echocardiography and cardiac catheterization were performed in all patients. We also enrolled 17 control patients without HF. EAC in the HF patients was significantly higher than that in the control patients (median EAC; 0.53 vs. 0.38 ppm, P=0.012). EAC positively correlated with blood total ketone bodies (r=0.454, P<0.001), NYHA class (r=0.489, P<0.001), and plasma B-type natriuretic peptide (r=0.316, P=0.001). Right heart catheterization revealed that EAC significantly correlated with pulmonary capillary wedge pressure (PCWP, r=0.377, P<0.001). Receiver-operating characteristic analysis revealed that EAC >1.05 ppm was associated with PCWP ≥18 mmHg (area under the curve [AUC] 0.726, sensitivity 50%, specificity 89%). EAC was shown to be a comparable diagnostic biomarker for HF to BNP (AUC 0.760, sensitivity 80%, specificity 70%). CONCLUSIONS: EAC may be a novel noninvasive biomarker that correlates hemodynamic severity in non-ischemic chronic HF. (Circ J 2016; 80: 1178-1186).

RESUMEN

Hypertrophic cardiomyopathy (HCM) with systolic dysfunction carries a poor prognosis. Although late gadolinium enhancement (LGE) on cardiac magnetic resonance is associated with adverse cardiac events in HCM and is inversely related to left ventricular ejection fraction (LVEF), it is unknown whether LGE or LVEF more accurately predicts adverse cardiac events in HCM with systolic dysfunction. We retrospectively assessed the extent of LGE with a threshold of 6 standard deviations in 46 consecutive HCM patients with systolic dysfunction defined as LVEF <50 % (average 35 ± 12 %) who underwent cardiac magnetic resonance (35 males, mean age 59 ± 14 years). They were followed up over 1755 ± 594 days. The composite adverse cardiac events end point included cardiovascular death, lethal arrhythmia, cardioembolic stroke, and unplanned heart failure hospitalization. LGE was detected in all patients, and the mean extent was 30 ± 15 %. Twenty-nine patients developed adverse cardiac events. Multivariate Cox proportional hazard analysis revealed the extent of LGE as a good independent predictor of adverse cardiac events. Risk increased with the extent of LGE (hazard ratio = 1.62/10 % increase in LGE, 95 % confidence interval = 1.23-2.15, p < 0.001). LVEF was inversely related to the extent of LGE (r = -0.44; p = 0.002) and was also an independent predictor of adverse cardiac events. Risk decreased with LVEF (hazard ratio = 0.68/10 % increase in LVEF, 95 % confidence interval = 0.51-0.91, p = 0.010). The Akaike information criterion evaluating the fit of a model demonstrated that the extent of LGE was a better independent predictor of MACE than LVEF (Akaike information criterion = 172.20 and 178.09, respectively).The extent of LGE was a good independent predictor of adverse cardiac events and reflected mortality and morbidity more precisely than LVEF in HCM with systolic dysfunction.

RESUMEN

Although counter-regulation between B-type natriuretic peptide (BNP) levels and renin-angiotensin-aldosterone system (RAAS) activation in heart failure (HF) has been suggested, whether the regulation is preserved in acute decompensated heart failure (ADHF) patients remains unclear. This study aimed to determine: (1) the relationship between RAAS activation and clinical outcomes in ADHF patients, and (2) the relationships between plasma BNP levels and degrees of activation in RAAS factors. This study included ADHF patients (n = 103, NYHA3-4, plasma BNP > 200 pg/ml). We studied the predictability of RAAS factors for cardiovascular events and the relationships between plasma BNP levels and the degrees of activation in RAAS factors, which were evaluated by plasma renin activity (PRA) and aldosterone concentration (PAC). PRA was a strong predictor of cardiovascular (CV) events over 1 year, even after accounting for plasma BNP levels (hazard ratio (HR): 1.04, CI [1.02-1.06], p < 0.01) and medication such as RAAS blockers (HR: 1.03, CI [1.01-1.05], p < 0.01), whereas PAC was borderline-significant (univariate analysis, p = 0.06). Cut-off value of PRA (5.3 ng/ml/h) was determined by AUC curve. Of the enrolled patients, higher PRA was found in 40 % of them. Although no correlation between the plasma BNP levels and PRA was found (p = 0.36), after adjusting for hemodynamic parameters, eGFR and medication, a correlation was found between them (p = 0.01). Elevated RAAS factors were found in a substantial number of ADHF patients with high plasma BNP levels in the association with hemodynamic state, which predicts poor clinical outcomes. The measurements of RAAS factors help to stratify ADHF patients at risk for further CV events.

RESUMEN

BACKGROUND: Basal thinning of the interventricular septum (IVS) is an important diagnostic feature of cardiac sarcoidosis (CS), but its long-term prognostic significance remains unclear. METHODS AND RESULTS: We examined 74 consecutive patients who were diagnosed with CS. Basal IVS thickness at a point located 10 mm from the aortic annulus was measured. IVS thickness at the left ventricular minor axis level (IVS) was also measured according to the recommended procedure of the American Society of Echocardiography. Patients were divided into 2 groups based on the presence or absence of basal IVS thinning, which was defined as basal IVS ≤4 mm and/or basal IVS/IVS ratio ≤0.6. Basal IVS thinning was observed in 21 patients and was associated with greater long-term adverse events during follow-up (5.1±2.5 years), although the baseline characteristics were comparable between groups (overall, P<0.01; all-cause death, P=0.53; symptomatic arrhythmias, P<0.01; heart failure admission, P=0.027). Multivariate analysis showed basal IVS thinning was an independent determinant of long-term adverse events (hazard ratio 2.86, 95% confidence interval 1.31-6.14) even after adjustment for existing prognostic variables. CONCLUSIONS: The presence of basal IVS thinning at the time of CS diagnosis was associated with poor long-term clinical outcomes, suggesting its prognostic significance in patients with CS.

RESUMEN

BACKGROUND: Cardiac involvement is the worst prognostic determinant in patients with sarcoidosis, but the long-term prognostic significance of corticosteroid therapy for cardiac sarcoidosis (CS) remains unclear. METHODS AND RESULTS: We examined 83 consecutive patients diagnosed with CS. Patients were divided into 2 groups based on the presence or absence of corticosteroid therapy at diagnosis. Patients with corticosteroid therapy had lower age and higher rate of positive findings in the myocardium on gallium scintigraphy (Ga) at diagnosis than those without. LVEF, biomarkers, and use of cardiovascular medication were similar between the 2 groups. During the follow-up (7.6±4.4 years), corticosteroid therapy was associated with fewer long-term adverse events (overall, P=0.005; cardiac death, P=0.92; symptomatic arrhythmias, P=0.89; heart failure admission, P<0.0001) and a greater % increase in LVEF than those without (7.9±36.3% vs. -16.7±34.8%, P=0.03). On Cox proportional hazards modeling, corticosteroid therapy (HR, 0.41; 95% CI: 0.20-0.89) was an independent determinant of long-term adverse event-free survival, but age, sex, LVEF, and Ga findings were not. CONCLUSIONS: Corticosteroid therapy might have a beneficial effect on long-term clinical outcome in CS patients, particularly by reduction of heart failure admission and retarding the progression of LV systolic dysfunction.
