Discrepancy between angiographic percent (%) diameter stenosis and fractional flow reserve (FFR) exists in non-left main bifurcation lesions. The aim of this study was to compare severity FFR jailed ostial left circumflex artery (LCX) lesions after (LM)-to-left anterior descending (LAD) crossover stenting. Twenty-nine (n=29) patients with distal LM or LAD treated by LM-to-LAD stenting were consecutively enrolled. After successful stenting, measured at the LCX. Additional intervention...
Objectives Beneficial effects of overweight and obesity on mortality after acute myocardial infarction (AMI) have been described as "Body Mass Index (BMI) paradox". However, the BMI is still debate. We analyzed association between 1-year clinical outcomes AMI. Methods Among 13,104 AMI patients registered in Korea Acute Myocardial Infarction Registry-National Institute Health (KAMIR-NIH) November 2011 December 2015, 10,568 who eligible for this study were classified into 3 groups according to...
Background: Patients with heart failure a preserved ejection fraction (HFPEF) have high N‐terminal pro‐B‐type natriuretic peptide (NT‐pro‐BNP) level and ratio of early transmitral inflow to diastolic velocity the mitral annulus (E/E′) derived from tissue Doppler imaging (TDI). Because left atrial volume indexed body surface area (LAVI) is believed reflect chronic dysfunction, we assessed ability LAVI E/E′ predict NT‐pro‐BNP in patients HFPEF. Methods: One hundred forty‐eight HFPEF (ejection...
Efficacy of combined intravascular ultrasound (IVUS) parameters in functional significance prediction and discrepancy between IVUS fractional flow reserve (FFR) have not been well defined. This study therefore aimed to: 1) evaluate the diagnostic accuracy parameters, namely minimal lumen area (MLA) percent plaque burden (%PB), coronary artery stenosis; 2) define factors that affect relation FFR value parameters.At 11 international centres, measurements were concurrently performed 945 major...
Abstract Background After acute myocardial infarction (AMI), the replicated phenomenon of obesity paradox, i.e., appearing to be associated with increased survival, has not been evaluated in stabilized (i.e., without clinical events within 1 month post AMI) Asian patients diabetes mellitus (DM). Methods Among 1192 DIabetic Acute Myocardial InfarctiON Disease (DIAMOND) Korean multicenter registry between April 2010 and June 2012, 2-year cardiac all-cause death were compared according (body...
Background/Aims In patients with heart failure (HF), N-terminal prohormone brain natriuretic peptide (NT-ProBNP) is a standard prognostic indicator. addition, uric acid (UA) was recently established as marker for poor outcome in chronic HF. The aim of this study to determine the combined role UA and NT-ProBNP markers short-term outcomes acute (AHF). Methods levels were determined 193 (age, 69 ± 13 years; 76 males) admitted AHF. Patients followed 3 months evaluated cardiovascular events,...
Although uric acid (UA) level has been associated with an increased risk of cardiovascular events, it is unclear whether UA can provide greater prognostic information than N‐terminal pro B‐type natriuretic peptide (NT‐proBNP) in advanced heart failure nonischemic dilated cardiomyopathy (DCM). and NT‐proBNP values were obtained from a total 122 DCM patients. Development clinical events during follow‐up was defined as the composite cardiac death readmission for failure. During follow‐up, there...
Background and Objectives：Arterial stiffness assessed non-invasively with the aortic pulse wave velocity (PWV) has been associated atherosclerosis in coronary arteries also cardiovascular mortality. The aim of this study was to determine whether arterial may predict severity artery disease (CAD). Subjects Methods：We enrolled 106 consecutive, symptomatic patients (males: 71 (67%), mean age: 57.0±10.5 years) who underwent angiography. extent CAD defined by single or multiple vessel according...
The phenomenon of obesity paradox after acute myocardial infarction (AMI) has been reported under strong recommendation statin therapy. However, the impact therapy on this not investigated. This study investigated 1-year mortality according to AMI. A total 2745 AMI patients were included from Korea Acute Myocardial Infarction Registry 1:4 propensity score matching analysis (n = 549 for nonstatin group and n 2196 group). Primary secondary outcomes all-cause cardiac death, respectively. During...
Few studies have explored the clinical potentials of combined Cystatin C (Cys) and uric acid (UA) in heart failure (HF). The authors evaluated Cys UA as predictors outcomes compared with conventional renal biomarkers. This prospective cohort study included 587 HF patients presenting dyspnea. At admission, Cys, UA, other measures including serum urea nitrogen (BUN), creatinine (Cr), glomerular filtration rate (GFR) were obtained. primary endpoint was composite cardiac death rehospitalization...
Carcinoid heart disease is characterized by valve dysfunction as well carcinoid symptomatology. We report a case of associated with primary ovarian tumor. A 60-year-old woman presented for dyspnea evaluation history facial flushing, telangiectatic skin changes, and pitting edema both lower extremities. Chest radiography showed cardiomegaly, echocardiography revealed an isolated, severe tricuspid regurgitation without left-sided valvular dysfunction. The leaflets were severely retracted...
Background Despite improved long-term safety of biodegradable polymer (BP) drug-eluting stents (DES) compared to first-generation durable (DP) DES, data on the and efficacy BP-DES with second-generation (2G) DP-DES in patients acute myocardial infarction (AMI) are limited. Hypothesis To evaluate 2G-DP-DES higher stent thrombosis (ST) risk setting AMI. Methods A total 3359 AMI who received either (n = 261) or 3098) were included from Korea Acute Myocardial Infarction Registry (KAMIR)....
Clinical Outcomes in Patients with Deferred Coronary Lesions according to Disease Severity Assessed by Fractional Flow ReserveData on the clinical outcomes deferred coronary lesions functional severity have been limited.This study evaluated of fractional flow reserve (FFR) grade using Korean FFR registry data.Among 1,294 patients and 1,628 registry, 665 781 were included this study.All participants consecutively categorized into 4 groups FFR; group 1: ≥ 0.96 (n = 56), 2: 0.86-0.95(n 330), 3:...
Abstract Background The aim of this study was to evaluate and compare the clinical angiographic outcomes 3 drug‐eluting stents (DES) in patients with large vessel diameter single coronary artery lesions. Hypothesis efficacy DESs may be similar. Methods A total 411 consecutive who visited university hospitals from June 2004 December 2007 had a lesion which treated use DES that 3.5 mm were enrolled study. Patients divided into stent groups: Paclitaxel‐eluting (PES, n = 105), Sirolimus‐eluting...
Background and Objectives:Percutaneous coronary intervention (PCI) for unprotected left main artery (LMCA) stenosis is a promising technique in the drug-eluting stent era. However, there lack of data as to impact lesion location LMCA on procedural postprocedural outcomes. The aim this study evaluate effect Subjects Methods: From July 2003 January 2006, we enrolled 82 patients (Males: n=49), who underwent PCI at Yeungnam University Medical Center, Keimyung Dong-san Hospital In-je Baik Busan....
