Implantable cardioverter-defibrillator (ICD) has been increasingly used to prevent sudden death in patients with high risk of ventricular arrhythmias (VAs). Chronic total occlusion (CTO) is a severe condition of coronary artery disease. However, the prognostic impact of CTO in ICD recipients remains controversial. We systematically searched the PubMed, EMBASE, and Cochrane databases for documents published before October 1, 2017 to identify studies that investigated the prognostic impact of CTO on VAs and all-cause mortality (ACM) in ICD recipients...

Aims: Plaque erosion is a significant substrate of acute coronary thrombosis. This study sought to determine in vivo predictors of plaque erosion in patients with ST-segment elevation myocardial infarction (STEMI). Methods and results: A prospective series of 822 STEMI patients underwent pre-intervention optical coherence tomography. Using established diagnostic criteria, 209 had plaque erosion (25.4%) and 564 had plaque rupture (68.6%). Plaque erosion was more frequent in women <50 years when compared with those ≥50 years of age (P = 0...

INTRODUCTION: Percutaneous endovascular therapy is an accepted and preferred procedure for symptomatic subclavian artery disease. However, the technical feasibility and effectiveness of treating chronic total occlusion of the subclavian artery with this approach is uncertain. We aimed to evaluate the initial and mid-term results of endovascular therapy for patients with symptomatic chronic total occlusion of the left subclavian artery. METHODS: Consecutive patients who underwent balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery between January 2010 and February 2014 were included...

We assessed the subsequent risk of cholelithiasis development in patients with inflammatory bowel diseases (IBDs) such as Crohn's disease (CD) or ulcerative colitis (UC). We identified 8186 patients who aged ≥20 years and were diagnosed with IBD between 2000 and 2010 as the study cohort. A total of 8186 patients without IBD were selected by frequency-matching according to age, sex, comorbidities, and the index date of diagnosis, and they were identified as the control cohort. To measure the incidence of cholelithiasis, all patients were followed up until the end of 2011...

The 2017 American College of Cardiology/American Heart Association hypertension guidelines diagnose hypertension if systolic blood pressure (SBP) is ≥ 130 mmHg or diastolic blood pressure (DBP) is ≥ 80 mmHg. Increased BP is SBP 120-129 mmHg with DBP < 80 mmHg. Lifestyle measures should be used to treat individuals with increased BP. Lifestyle measures plus BP-lowering drugs should be used for secondary prevention of recurrent cardiovascular events in individuals with clinical cardiovascular disease (coronary heart disease, congestive heart failure, or stroke) and an average SBP ≥ 130 mmHg or an average DBP ≥ 80 mmHg...

Importance: Health care spending in the United States is a major concern and is higher than in other high-income countries, but there is little evidence that efforts to reform US health care delivery have had a meaningful influence on controlling health care spending and costs. Objective: To compare potential drivers of spending, such as structural capacity and utilization, in the United States with those of 10 of the highest-income countries (United Kingdom, Canada, Germany, Australia, Japan, Sweden, France, the Netherlands, Switzerland, and Denmark) to gain insight into what the United States can learn from these nations...

BACKGROUND: While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. METHODS: In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery...

OBJECTIVE: Performing lower extremity bypass (LEB) in actively smoking claudicants remains controversial. Whereas some surgeons advocate a strict nonoperative approach to active smokers, citing perceived inferior outcomes, others will proceed with surgical bypass if the patient is anatomically suited and medical management has failed. The purpose of this study was to determine the impact of active smoking on LEB outcomes among claudicants. METHODS: All patients undergoing infrainguinal LEB for claudication in the Vascular Study Group of New England from 2003 to 2016 were analyzed...

PURPOSE: Chronic pancreatitis (CP) can cause fat or bile acid malabsorption due to exocrine insufficiency. Fat or bile acid malabsorption has been reported to increase the risk of urolithiasis through increased intestinal oxalate absorption. However, no studies have reported an association between CP and urolithiasis. METHODS: We identified 15,848 patients (age: ≥20 years) diagnosed as having CP between 2000 and 2010 from the National Health Insurance Research Database as the study cohort...

Differential diagnosis of lower limb oedema is a common exercise in clinical practice. Taking the example of a patient presenting with such clinical picture in the presence of type 2 diabetes and arterial hypertension with coronary heart disease and chronic kidney disease as comorbidities, we discuss here the respective contributions of congestive heart failure, renal impairment (and possibly nephrotic syndrome) and liver disease in the development of lower limb oedema. The focus is made on a careful patient history and a meticulous clinical examination, two crucial steps that should allow prescribing well selected simple complementary procedures and rapidly make the final diagnosis...

Vascular adverse events (VAEs) in chronic myeloid leukemia (CML) patients treated with nilotinib (NIL) has become a; however, studies on strategies to prevent VAEs remain limited. Therefore, the present study investigated VAEs in 19 CML patients treated with NIL at our hospital. The median age of the patients was 65 years and median follow-up period was 55 months after the initiation of NIL. VAEs occurred in 8 patients (peripheral artery disease (PAD), n=6; cerebral infarction (CI), n=3; coronary artery disease (CAD), n=4)...

BACKGROUND/AIMS: Variability in the grade of atherosclerosis among patients with chronic kidney disease (CKD) could affect the ultrasound measurements of intima media thickness (IMT). We sought to investigate IMTs of carotid (cIMT) and femoral (fIMT) arteries in CKD patients and assess the degree of their correlation with histopathological atherosclerosis. METHODS: Eighty-nine out of 99 enrolled subjects completed this study. The subjects were divided into 3 groups: 34 patients with CKD (Case group), 31 with coronary artery disease undergoing coronary artery bypass graft (CABG, positive control group), and 24 healthy kidney donors (negative control group)...

Atherosclerosis is a chronic, progressive, and multifactorial disease modulated by genetic and environmental factors. In recent years, the paradigm that explained atherosclerosis as resulting from a complex interaction between factors not accessible to medical intervention, and modifiable risk factors has changed. In this paradigm, alterations in lipid metabolism were the pivotal concept of atherosclerosis as a chronic degenerative disease. In the last years, an increasing number of observations have shown that the innate and adaptive immune responses to lipoprotein deposition and oxidation in the arterial wall significantly influence atherosclerosis...

INTRODUCTION: Cardiovascular disease is the most common cause of death in chronic hemodialysis patients(1). Cardiac surgery in hemodialysis patients exposes to higher risks inherent in the particular status of these patients. The aim of our study is to report the perioperative particularities of hemodialysis patients undergoing cardiac surgery, and to determine the impact of preoperative clinical status on hospital and late morbidity and mortality. METHODS: Between January 1998 and December 2012, 48 patients in chronic hemodialysis (HD) and candidates for cardiac surgery on cardiopulmonary bypass were retrospectively included...
