Optimal low-density lipoprotein cholesterol target level in Korean acute myocardial infarction patients (<70 mg/dL vs. <55 mg/dL): Based on Korea acute myocardial infarction registry-National Institute of Health.

Background: Current treatment guidelines for acute myocardial infarction (AMI) recommend lowering low density lipoprotein cholesterol (LDL-C). However, previous clinical studies among East Asian AMI patients failed to prove its clinical efficacy of lipid lowering therapy based on Western target LDL-C level. Thus, the purpose of this study is directly to compare the clinical outcomes of target LDL-C < 70 mg/dL and < 55 mg/dL and identify optimal target LDL-C level and in Korean AMI patients.

Post-operative Atrial Fibrillation Impacts on Outcomes in Transcatheter and Surgical Aortic Valve Replacement.

Atrial fibrillation (AF) in severe aortic stenosis (AS) has poor outcomes after transcatheter and surgical aortic valve replacement (TAVR and SAVR, respectively). We compared the incidence of AF after aortic valve replacement (AVR) according to the treatment method and the impact of AF on outcomes. We investigated the incidence of AF and clinical outcomes of AVR according to whether AF occurred after TAVR and SAVR after propensity score (PS)-matching for 1 year follow-up.

Predictors of Clinical Outcome in Patients with Angiographically Intermediate Lesions with Minimum Lumen Area Less than 4 mm Using Intravascular Ultrasound in Non-Proximal Epicardial Coronary Artery.

We investigated predictors of major adverse cardiac events (MACE) with two years after medical treatment for lesions with angiographically intermediate lesions with intravascular ultrasound (IVUS) minimum lumen area (MLA) <4 mm in non-proximal epicardial coronary artery. We retrospectively enrolled 104 patients (57 males, 62±10 years) with angiographically intermediate lesions (diameter stenosis 30-70%) with IVUS MLA <4 mm in the non-proximal epicardial coronary artery with a reference lumen diameter between 2.25 and 3.
