The influence of body mass index (BMI) on the outcome of patients with colorectal cancer (CRC) is largely unknown, particularly in an Asian population. Therefore, we investigated the influence of BMI on survival of patients who underwent surgical treatment for CRC in Korean population. This prospective cohort study included CRC patients who underwent(More)
OBJECTIVE The aim of this study was to evaluate the impact of left ventricular diastolic dysfunction on predicting postoperative pulmonary edema and major cardiovascular events (MACE) in patients who underwent low- or intermediate-risk noncardiac surgery. METHODS A total of 692 patients aged >60 years who underwent transthoracic echocardiography (TTE)(More)
BACKGROUND/AIMS The proper assessment of the current disease status of patients with chronic hepatitis B would be valuable for establishing optimal management strategies. METHODS The clinical and laboratory characteristics of 2,954 patients with current or previous antiviral treatment (46.2±10.8 years, 69.7% male) enrolled from 46 referral hospitals and(More)
Left ventricular (LV) remodeling in systemic arterial hypertension causes electrical conduction delay and impairs synchronous contraction, which may contribute to the development of heart failure. This study aimed to assess the change of LV mechanics in hypertension by layer-specific dyssynchrony. One hundred and twenty-one patients with primary(More)
The association between colorectal cancer (CRC) and diverticulosis is uncertain, and there is little data reported in Asia. This study examined the association of both diseases based on the computed tomographic colonography (CTC). This study was designed as a case–control study. Korean subjects undergoing CTC between April 2002 to April 2008 in Samsung(More)
OBJECTIVE Because patients with new-onset diabetes mellitus (DM) have a significantly increased likelihood of association with pancreatic cancer, we need to select the subgroup of diabetic patients who have more chance of association with pancreatic cancer. METHODS We retrospectively reviewed medical records of case group (151 patients with pancreatic(More)
BACKGROUND Systemic arterial hypertension causes functional and structural remodelling of the left ventricle, which is related to subclinical left ventricular (LV) dysfunction and heart failure. This study assessed LV functional change using layer-specific strain and its relationship to structural remodelling in patients with hypertension. METHODS A total(More)
The discriminative ability of the widely used CHADS2 and CHA2DS2-VASc scores for risk stratification of thromboembolism in atrial fibrillation (AF) is known as modest. Some echocardiographic parameters are known risk factors for thromboembolism. This study aimed to evaluate whether combining echocardiographic parameters with CHADS2 and CHA2DS2-VASc scores(More)
BACKGROUND AND OBJECTIVE Bronchoscopic resection of endobronchial hamartomas has been reported to have a favourable outcome. This study describes the bronchoscopic features of endobronchial hamartoma and reports the clinical outcome of bronchoscopic intervention. METHODS A retrospective analysis was conducted of patients with histologically proven(More)
There has been a rising interest in interarm blood pressure difference (IAD), due to its relationship with peripheral arterial disease and its possible relationship with cardiovascular disease. This study aimed to characterize hypertensive patients with a significant IAD in relation to cardiovascular risk. A total of 3699 patients (mean age, 61 ± 11 years)(More)
