Background/Aims:
The continuous flow left ventricular assist device (cf-LVAD) has improved the survival of chronic end-stage heart failure (HF) patients. Here we describe our clinical experience of the initial 50 LVAD patients from a single center.
Methods:
A total of 50 patients underwent LVAD implantation as bridge to transplantation (BTT; n = 28, 56%), bridge to candidacy (BTC; n = 2, 4%), or as destination therapy (DT; n = 20, 40%) from 2012 to 2019. Pre-implant characteristics and clinical outcomes were compared between BTT/BTC and DT.
Results:
The median age of patients was 67 years (range, 59 to 73). Men were more likely to receive LVAD (76% vs. 24%) than women. DT patients were older, had smaller body surface area, and worse laboratory profiles than BTT/BTC patients. There was no in-hospital mortality. During an average of 14 months (range, 8 to 23), the all-cause mortality was 22%. The first-year survival was 86 and 90% in BTT/BTC and DT groups, respectively. Hemorrhagic stroke was the most common cause (27%) of death. In the BTT/BTC group, 22 patients successfully underwent heart transplantation during median duration of 10 months (range, 7 to 14). The most common post-LVAD complication during the first year of LVAD implantation was major bleeding (44%). A significant proportion (76%) of patients experienced rehospitalization with gastrointestinal bleeding as the most common cause.
Conclusions
We describe short-term clinical outcome of LVAD patients from a single center for the first time in Korea. With the newer generation LVAD and a dedicated team approach, improved clinical outcomes of LVAD for end-stage HF are expected.

PURPOSE: Prediabetes is an independent risk factor for cardiovascular disease. However, data on the long term adverse clinical outcomes of prediabetic patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) are scarce. MATERIALS AND METHODS: The study population comprised 674 consecutive non-diabetic patients who underwent elective PCI between April 2007 and November 2010. Prediabetes was defined as hemoglobin A1c (HbA1c) of 5.7% to 6.4%. Two-year cumulative clinical outcomes of prediabetic patients (HbA1c of 5.7% to 6.4%, n=242) were compared with those of a normoglycemic group (< 5.7%, n=432). RESULTS: Baseline clinical and angiographic characteristics were similar between the two groups, except for higher glucose levels (104.8±51.27 mg/dL vs. 131.0±47.22 mg/dL, p < 0.001) on admission in the prediabetes group. There was no significant difference between the two groups in coronary angiographic parameters, except for a higher incidence of diffuse long lesion in the prediabetes group. For prediabetic patients, trends toward higher incidences of binary restenosis (15.6% vs. 9.8 %, p=0.066) and late loss (0.71±0.70 mm vs. 0.59±0.62 mm, p=0.076) were noted. During the 24 months of follow up, the incidence of mortality in prediabetic patients was higher than that in normoglycemic patients (5.5% vs. 1.5%, p=0.007). CONCLUSION: In our study, a higher death rate and a trend toward a higher incidence of restenosis in patients with prediabetes up to 2 years, compared to those in normoglycemic patients, undergoing elective PCI with contemporary DESs.

PURPOSE: Many recent studies have reported that successful percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for chronic total occlusion (CTO) has more beneficial effects than failed CTO-PCI; however, there are only limited data available from comparisons of successful CTO-PCI with medical therapy (MT) in the Korean population. MATERIALS AND METHODS: A total of 840 consecutive CTO patients who underwent diagnostic coronary angiography, receiving either PCI with DESs or MT, were enrolled. Patients were divided into two groups according to the treatment assigned. To adjust for potential confounders, propensity score matching (PSM) analysis was performed using logistic regression. Individual major clinical outcomes and major adverse cardiac events, a composite of total death, myocardial infarction (MI), stroke, and revascularization, were compared between the two groups up to 5 years. RESULTS: After PSM, two propensity-matched groups (265 pairs, n=530) were generated, and the baseline characteristics were balanced. Although the PCI group showed a higher incidence of target lesion and vessel revascularization on CTO, the incidence of MI tended to be lower [hazard ratio (HR): 0.339, 95% confidence interval (CI): 0.110 to 1.043, p=0.059] and the composite of total death or MI was lower (HR: 0.454, 95% CI: 0.224 to 0.919, p=0.028), compared with the MT group up to 5 years. CONCLUSION: In this study, successful CTO PCI with DESs was associated with a higher risk of repeat PCI for the target vessel, but showed a reduced incidence of death or MI.
