Background@#The US Food and Drug Administration (FDA) and European Medicines Agency (EMA) approved empagliflozin for reducing cardiovascular mortality and heart failure (HF) hospitalization in patients with both HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). However, limited data are available on the generalizability of empagliflozin to clinical practice. Therefore, we evaluated real-world eligibility and potential cost-effectiveness based on a nationwide prospective HF registry. @*Methods@#A total of 3,108 HFrEF and 2,070 HFpEF patients from the Korean Acute Heart Failure (KorAHF) registry were analyzed. Eligibility was estimated by inclusion and exclusion criteria of EMPagliflozin outcomE tRial in Patients With chrOnic heaRt Failure With Reduced Ejection Fraction (EMPEROR-Reduced) and EMPagliflozin outcomE tRial in Patients With chrOnic heaRt Failure With Preserved Ejection Fraction (EMPEROR-Preserved) trials and by FDA & EMA label criteria. The cost-utility analysis was done using a Markov model to project the lifetime medical cost and quality-adjusted life year (QALY). @*Results@#Among the KorAHF patients, 91.4% met FDA & EMA label criteria, while 44.7% met the clinical trial criteria. The incremental cost-effectiveness ratio of empagliflozin was calculated at US$6,764 per QALY in the overall population, which is far below a threshold of US$18,182 per QALY. The cost-effectiveness benefit was more evident in patients with HFrEF (US$5,012 per QALY) than HFpEF (US$8,971 per QALY). @*Conclusion@#There is a large discrepancy in real-world eligibility for empagliflozin between FDA & EMA labels and clinical trial criteria. Empagliflozin is cost-effective in HF patients regardless of ejection fraction in South Korea health care setting. The efficacy and safety of empagliflozin in real-world HF patients should be further investigated for a broader range of clinical applications.

Background and Objectives@#Veno-arterial extracorporeal membrane oxygenation (VAECMO) as a bridge to eventual heart transplantation (HT) is increasingly used worldwide.However, the effect of different VA-ECMO types on HT outcomes remains unclear. @*Methods@#This was a retrospective observational study of 111 patients receiving VA-ECMO and awaiting HT. We assessed 3 ECMO configuration groups: peripheral (n=76), central (n=12), and peripheral to central ECMO conversion (n=23). Cox proportional hazards regression and landmark analysis were conducted to analyze the effect of the ECMO configuration on HT and in-hospital mortality rates. We also evaluated adverse events during ECMO support. @*Results@#HT was performed in the peripheral (n=48, 63.2%), central (n=10, 83.3%), and conversion (n=11, 47.8%) ECMO groups (p=0.133) with a median interval of 10.5, 16, and 30 days, respectively (p<0.001). The cumulative incidence of HT was significantly lower in the conversion group (hazard ratio, 0.292, 95% confidence interval, 0.145–0.586, p=0.001).However, there was no difference in in-hospital mortality (log-rank p=0.433). In the landmark analysis, in-hospital mortality did not differ significantly among the 3 groups.Although we did note a trend toward lower HT in the conversion group, the difference was not statistically significant. Surgical site bleeding occurred mainly in the central, while limb ischemia occurred mainly in the peripheral groups. @*Conclusions@#We suggest that if patients are being stably supported with their initial ECMO configuration, whether it is central or peripheral, it should be maintained, and ECMO conversion should only be cautiously performed when necessary.

Purpose@#Epidemiological data on injuries resulting from ice hockey and their management are lacking in Korea. A comprehensive analysis of such data is crucial for the effective prevention and management of ice hockey injuries. This study aimed to determine the epidemiological profile of ice hockey injuries and their management among elite Korean players. @*Methods@#The descriptive epidemiological study involved three semiprofessional male ice hockey teams and used a retrospective self-reported questionnaire for assessment. The data collected included demographic characteristics such as player positions and stick-side preferences, injured body parts, injury types, treatment methods, and the decision-maker for returning to sports. @*Results@#A total of 68 players were included in the study, of whom 58 (85.3%) experienced moderate-to-severe orthopedic injuries. Among the reported injuries, 93 (77.5%) occurred during the games, with player-to-player contact being the most frequent cause of such injuries. The decision to return to sports in 53 cases (44.2%) was made by the medical staff, whereas players and nonmedical staff made that decision in 67 cases (55.8%). The decision-making process of the medical staff for allowing players to return to sports was significantly associated with the player’s position and whether the injury required surgery. @*Conclusion@#The study emphasizes the high prevalence of orthopedic injuries among elite ice hockey players in Korea and the importance of injury prevention strategies. It also highlights the need for increased involvement of medical staff in return-to-play decisions to ensure successful recovery of players and their reintegration into the competition.

Background@#Prolonged ischemic time is a risk factor for primary graft dysfunction in patients who undergo heart transplantation. We investigated the effect of a supplemental cardioplegia infusion before anastomosis in patients with long ischemic times. @*Methods@#We identified 236 consecutive patients who underwent orthotopic heart transplantation between February 2010 and December 2014. Among them, the patients with total ischemic times of longer than 3 hours (n=59) were categorized based on whether they were administered a complementary cardioplegia solution (CPS) immediately before implantation (CPS+, n=30; CPS−, n=29). @*Results@#The mean total ischemic times in the CPS+ and CPS− groups were 238.1±30.1 minutes and 230.1±28.2 minutes, respectively (p=0.3). The incidence of left ventricular primary graft dysfunction (CPS+, n=6 [20.0%]; CPS−, n=5 [17.2%]; p=0.79) was comparable between the groups. In the Kaplan-Meier survival analysis, no significant difference in overall survival at 5 years was observed between the CPS+ and CPS− groups (83.1%±6.9% vs. 89.7%±5.7%, respectively; log-rank p=0.7). No inter-group differences in early mortality (CPS+, n=0; CPS−, n=1 [3.4%]; p=0.98) or complications were observed. @*Conclusion@#The additional infusion of a cardioplegia solution immediately before implantation in patients with longer ischemic times is a simple, reproducible, and safe procedure. However, we did not observe benefits of this strategy in the present study.

Background/Aims@#This study investigated the prognostic power of corrected QT (QTc) interval in patients with acute heart failure (AHF) according to sex. @*Methods@#We analyzed multicenter Korean Acute Heart Failure registry with patients with AHF admitted from 2011 to 2014. Among them, we analyzed 4,990 patients who were followed up to 5 years. Regarding QTc interval based on 12 lead electrocardiogram, patients were classified into quartiles according to sex. @*Results@#During follow-up with median 43.7 months, 2,243 (44.9%) patients died. The relationship between corrected QT interval and all-cause mortality followed a J-curve relationship. In Kaplan-Meier analysis, both sex had lowest mortality in the second QTc quartile. There were significant prognostic differences between the second and the fourth quartiles in male (log-rank p = 0.002), but not in female (log-rank p = 0.338). After adjusting covariates, the third (hazard ratio [HR], 1.185; 95% confidence interval [CI], 1.001 to 1.404; p = 0.049) and the fourth (HR, 1.404; 95% CI, 1.091 to 1.535; p = 0.003) quartiles demonstrated increased risk of mortality compared to the second quartile in male. In female, however, there was no significant difference across quartiles. QTc interval was associated with 5-year all-cause mortality in J-shape with nadir of 440 to 450 ms in male and 470 to 480 ms in female. @*Conclusions@#QTc interval was an independent predictor of overall death in male, but its significance decreased in female. The relationship between QTc interval and all-cause mortality was J-shaped in both sex.

Background@#β-blockers (BBs) are considered primary therapy in stable heart failure (HF) with reduced ejection fraction (HFrEF) without atrial fibrillation (AF); evidence-based benefits of BB on outcome have been documented. However, BBs have not been shown to improve mortality or reduce hospital admissions in HF patients with AF. This study assessed the relationship between BBs at discharge and relevant clinical outcomes in acute heart failure (AHF) patients with AF. @*Methods@#From the Korean Acute Heart Failure Registry, 936 HFrEF and 639 HF patients with preserved ejection fraction (HFpEF) and AF were selected. Propensity score (PS) matching accounted for BB selection bias when assessing associations. @*Results@#BB-untreated patients in the overall cohort of HFrEF and HFpEF had greater deteriorated clinical and laboratory characteristics. In the 670 PS-matched cohort of HFrEF patients, incidences of all clinical events at 60 days and 1 year were not different according to use of BBs. In the 470 PS-matched cohort of HFpEF, rehospitalization and composite outcome at 6 months and 1 year more frequently occurred in non-users of BBs. After adjusting for covariates in the multivariable Cox model of matched cohorts, BB was not associated with clinical outcomes at 60 days and 1 year in HFrEF with AF patients. In HFpEF patients with AF, BB use was associated with reduced 6-month (hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.20–0.74) and 1-year rehospitalization (HR, 0.53; 95% CI, 0.34–0.82). @*Conclusion@#In the HFrEF with AF PS-matched cohort, the use of BBs at discharge was not associated with clinical outcome. However, in HFpEF with AF, the use of BB was associated with reduced rehospitalization during the 6-month and 1-year follow up.

Background@#There are sparse data on the utilization rate of implantable cardioverterdefibrillator (ICD) and its beneficial effects in Korean patients with heart failure with reduced left ventricular ejection fraction (LVEF). @*Methods@#Among 5,625 acute heart failure (AHF) patients from 10 tertiary university hospitals across Korea, 485 patients with reassessed LVEF ≤ 35% at least 3 months after the index admission were enrolled in this study. The ICD implantation during the follow-up was evaluated. Mortality was compared between patients with ICDs and age-, sex-, and follow-up duration matched control patients. @*Results@#Among 485 patients potentially indicated for an ICD for primary prevention, only 56 patients (11.5%) underwent ICD implantation during the follow-up. Patients with ICD showed a significantly lower all-cause mortality compared with their matched control population: adjusted hazard ratio (HR) (95% confidence interval [CI]) = 0.39 (0.16–0.92), P = 0.032. The mortality rate was still lower in the ICD group after excluding patients with cardiac resynchronization therapy (adjusted HR [95% CI] = 0.09 [0.01–0.63], P = 0.015).According to the subgroup analysis for ischemic heart failure, there was a significantly lower all-cause mortality in the ICD group than in the no-ICD group (HR [95% CI] = 0.20 [0.06– 0.72], P = 0.013), with a borderline statistical significance (interaction P = 0.069). @*Conclusion@#Follow-up data of this large, multicenter registry suggests a significant underutilization of ICD in Korean heart failure patients with reduced LVEF. Survival analysis implies that previously proven survival benefit of ICD in clinical trials could be extrapolated to Korean patients.

BACKGROUND AND OBJECTIVES@#This second adult heart transplantation (HTx) report is based on Korean Organ Transplant Registry data submitted on 400 HTxs in recipients of all ages.@*METHODS@#From March 2014 to December 2017, a total of 400 HTxs were performed at 4 major centers in Korea. We analyzed demographics and characteristics according to transplant years. Patterns of immunosuppression, allograft rejection, and survival after HTx were analyzed. Donor and recipient age were highlighted.@*RESULTS@#Some distinct differences in HTx statistics were noted. Mean donor age increased significantly in the most recent years compared to 2014–2015, while mean recipient age did not change. The proportion of patients on pre-transplant extracorporeal membrane oxygenation (ECMO) increased over time. One-year and intermediate-term survival was significantly worse in patients on pre-transplant ECMO compared to those without mechanical support. Over the years, tacrolimus has increased to become the most frequently used calcineurin inhibitor over cyclosporine, while the number of patients using steroids both at discharge and 1-year follow-up has declined. Age did not affect 1-year survival, but significantly affected intermediate-term survival.@*CONCLUSIONS@#From 2014 to 2017, centers were willing to accept older donors to address increasing organ shortages and more patients received transplant under ECMO care. Increasing age was a strong independent factor for intermediate-term survival, however, post-transplant comorbidities did not differ among age groups. Further studies with longer follow-up duration are needed to better understand age-related post-transplant prognosis.

BACKGROUND AND OBJECTIVES@#Conflicting data exist regarding the prognostic implication of ventricular conduction disturbance pattern in patients with heart failure (HF). This study investigated the prognostic impact of ventricular conduction pattern in hospitalized patients with acute HF.@*METHODS@#Data from the Korean Acute Heart Failure registry were used. Patients were categorized into four groups: narrow QRS (<120 ms), right bundle branch block (RBBB), left bundle branch block (LBBB), and nonspecific intraventricular conduction delay (NICD). The NICD was defined as prolonged QRS (≥120 ms) without typical features of LBBB or RBBB. The primary endpoint was the composite of all-cause mortality or rehospitalization for HF aggravation within 1 year after discharge.@*RESULTS@#This study included 5,157 patients. The primary endpoint occurred in 39.7% of study population. The LBBB group showed the highest incidence of primary endpoint followed by NICD, RBBB, and narrow QRS groups (52.5% vs. 49.7% vs. 44.4% vs. 37.5%, p<0.001). In a multivariable Cox-proportional hazards regression analysis, LBBB and NICD were associated with 39% and 28% increased risk for primary endpoint (LBBB hazard ratio [HR], 1.392; 95% confidence interval [CI], 1.152–1.681; NICD HR, 1.278; 95% CI, 1.074–1.520) compared with narrow QRS group. The HR of RBBB for the primary endpoint was 1.103 (95% CI, 0.915–1.329).@*CONCLUSIONS@#LBBB and NICD were independently associated with an increased risk of 1-year adverse event in hospitalized patients with HF, whereas the prognostic impacts of RBBB were limited.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01389843

BACKGROUND AND OBJECTIVES@#Beta-blockers are indicated in patients with heart failure (HF) with reduced ejection fraction. However, their efficacy in patients with HF with preserved ejection fraction (HFpEF) is uncertain. We investigated the hypothesis that beta-blockers are associated with reduced adverse events in patients with HFpEF.@*METHODS@#The Korea Acute Heart Failure (KorAHF) is a prospective observational multicentre cohort study. The 5,625 patients hospitalized for acute HF syndrome in 10 tertiary university hospitals across the country have been consecutively enrolled between March 2011 and February 2014. Of these patients, 2,152 patients with HFpEF (ejection fraction ≥40%) were investigated. The primary outcome was all-cause mortality according to beta-blocker use.@*RESULTS@#During a median follow-up duration of 807 days, 702 patients died. In Cox proportional hazards model beta-blocker use was associated with a 14% reduced all-cause death (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.75–0.98), but not with reduce rehospitalization (HR, 1.03; 95% CI, 0.85–1.27). In the propensity-score matched population, beta-blockers were also associated with reduced all-cause death (HR, 0.80; 95% CI, 0.69–0.94) but not with reduced rehospitalization (HR, 1.08; 95% CI, 0.87–1.33).@*CONCLUSIONS@#In Korean patients with HFpEF, use of beta-blockers is associated with reduced all-cause death but not with reduced rehospitalization.

BACKGROUND/AIMS@#It is unknown whether different β-blockers (BBs) have variable effects on long-term survival of patients with heart failure with reduced ejection fraction (HFrEF). This study compares the effects of two BBs, carvedilol and bisoprolol, on survival in patients with HFrEF.@*METHODS@#The Korean Acute Heart Failure (KorAHF) registry is a prospective multicenter cohort that includes 5,625 patients who were hospitalized for acute heart failure (AHF). We selected 3,016 patients with HFrEF and divided this study population into two groups: BB at discharge (n = 1,707) or no BB at discharge (n = 1,309). Among patients with BB at discharge, subgroups were formed based on carvedilol prescription (n = 831), or bisoprolol prescription (n = 553). Propensity score matching analysis was performed.@*RESULTS@#Among patients who were prescribed a BB at discharge, 60.5% received carvedilol and 32.7% received bisoprolol. There was a significant reduction in all-cause mortality in those patients with HFrEF prescribed a BB at discharge compared to those who were not (BB vs. no BB, 26.1% vs. 40.8%; hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.52 to 0.67; p < 0.001). However, there was no significant difference in the rate of all-cause mortality between those receiving different types of BB (carvedilol vs. bisoprolol, 27.5% vs. 23.5%; HR, 1.21; 95% CI, 0.99 to 1.47; p = 0.07). Similar results were observed after propensity score matching analysis (508 pairs, 26.2% vs. 23.8%; HR, 1.10; 95% CI, 0.86 to 1.40; p = 0.47).@*CONCLUSIONS@#In the treatment of AHF with reduced EF after hospitalization, mortality benefits of carvedilol and bisoprolol were comparable.

BACKGROUND AND OBJECTIVES@#The prognostic impact of left axis deviation (LAD) on clinical outcomes in acute heart failure syndrome (AHFS) with left bundle branch block (LBBB) is unknown. The aim of this study was to determine the prognostic significance of axis deviation in acute heart failure patients with LBBB.@*METHODS@#Between March 2011 and February 2014, 292 consecutive AHFS patients with LBBB were recruited from 10 tertiary university hospitals. They were divided into groups with no LAD (n=189) or with LAD (n=103) groups according to QRS axis <−30 degree. The primary outcome was all-cause mortality.@*RESULTS@#The median follow-up duration was 24 months. On multivariate analysis, the rate of all-cause death did not significantly differ between the normal axis and LAD groups (39.7% vs. 46.6%, adjusted hazard ratio, 1.01; 95% confidence interval, 0.66, 1.53; p=0.97). However, on the multiple linear regression analysis to evaluate the predictors of the left ventricular ejection fraction (LVEF), presence of LAD significantly predicted a worse LVEF (adjusted beta, −3.25; 95% confidence interval, −5.82, −0.67; p=0.01). Right ventricle (RV) dilatation was defined as at least 2 of 3 electrocardiographic criteria (late R in lead aVR, low voltages in limb leads, and R/S ratio < 1 in lead V5) and was more frequent in the LAD group than in the normal axis group (p < 0.001).@*CONCLUSIONS@#Among the AHFS with LBBB patients, LAD did not predict mortality, but it could be used as a significant predictor of worse LVEF and RV dilatation (Trial registry at KorAHF registry, ClinicalTrial.gov, NCT01389843).

BACKGROUND AND OBJECTIVES: The Korean Organ Transplant Registry (KOTRY), which was the first national transplant registry in Korea, was founded by the Korean Society for Transplantation and the Korean Center for Disease Control in 2014. Here, we present the initial report of the Korean Heart Transplant Registry. METHODS: A total of 183 heart transplantation (HTPL) patients performed at 4 nationally representative hospitals were collected from April 2014 to December 2015. We analyzed donor and recipient characteristics, treatment patterns, and immediate post-transplantation outcomes. RESULTS: One hundred and eighty-three patients were enrolled. The mean age of the patients was 50.5±13.5 years. The mean age of the male recipients was 4 years greater than that of the female recipients (51.7±13.3 years vs. 47.9±13.7 years, p < 0.050). The mean age of donors was more than 12 years younger than that of heart recipients (37.6±10.1 years). Dilated cardiomyopathy was the predominant cause (69%) of heart failure in recipients, followed by ischemic heart diseases (14%) and valvular heart disease (4%). Rejection episodes were most frequent in the 1–6-month period after transplantation (48%), and rarely required intensive treatment. Infection episodes were most frequent <1 month after transplantation (66%) and bacterial and viral infections were equally reported. The 1-year survival rate was 91.6% and most mortality cases occurred during the perioperative period within 1 month after transplantation. CONCLUSION: With the establishment of the KOTRY in 2014, it is now possible to present nationwide epidemiological data for HTPL in Korea for the first time. The KOTRY is the first national HTPL registry in Korea, and will continue until 2023.

Combined heart-liver transplantation (CHLT) is an increasingly accepted treatment for select patients with advanced heart and liver disease. However, CHLT are infrequently performed, despite growing optimism about their effectiveness. Here, we report Asan Medical Center experience with CHLT in three patients presenting with advanced heart and liver failure. One patient died of brain swelling because of intractable hyperammonemia on postoperative day 9. The two other patients were still alive at 53 and 9 months postsurgery. None of these patients required readmission for cardiac or hepatic graft dysfunction and no rejection episodes were detected on routine cardiac biopsies. This is the first report of CHLT cases from Korea.
