The optimal decision regarding whether to repair or replace the tricuspid valve (TV) remains controversial in patients with very severe functional tricuspid regurgitation (TR). We sought to compare clinical outcomes of TV repair versus replacement for very severe TR associated with severe TV tethering. We included 96 consecutive patients (20 men, 58 ± 11 years of age) who had both severe tethering of TV and very severe functional TR and consequently underwent TV surgery during left-sided valve surgery. TV repair was performed on 79 patients (repair group), whereas 17 patients underwent TV replacement (replacement group)...

The aim of this study was to assess the image quality (IQ) and radiation dose of third-generation dual-source computed tomography (CT) coronary angiography (cCTA) in comparison with 64-slice single-source CT. This retrospective study included 140 patients (73 men, mean age 62 ± 11 years) with low-to-intermediate probability of coronary artery disease who underwent either third-generation dual-source cCTA using prospectively electrocardiography-triggered high-pitch spiral acquisition (n = 70) (group 1) or retrospective electrocardiography-gated cCTA on a 64-slice CT system (n = 70) (group 2)...

The Fontan procedure is increasingly being used to palliate univentricular physiology. It is a complex anatomic and physiologic repair that can fail at any age, often leaving heart transplantation as the only remaining solution. A meta-analysis was performed to achieve the aim of systematically evaluating the existing evidence for survival after heart transplantation in patients who have undergone a Fontan palliation. MEDLINE, Embase, PubMed, and Web of Science were searched for original research studies. The primary outcome was mortality at 1 and 5 years after transplantation...

Arterial calcification is associated with cardiovascular morbidity and mortality. To improve the understanding of the pathogenesis involved with iliac artery calcium (IAC), we sought to examine the associations between the burden of IAC with adiposity measures and peripheral artery disease (PAD). Participants (n = 1,236, 52% women, mean age 60 years) were drawn from the Framingham Heart Study Offspring cohort who underwent multidetector computed tomography. The extent of IAC was quantified based on calcified atherosclerotic plaques detected in the iliac arteries...

The comparative outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in diabetes mellitus (DM) patients are scarce. We aimed to assess and compare the outcomes of TAVR versus SAVR in DM patients using the Nationwide Inpatient Sample database from 2011 to 2013. A complete case analysis was performed for the multivariate analysis and cases with missing data were excluded. The primary end point was in-patient all-cause mortality and secondary outcomes were perioperative complications...

Prevalence of insulin resistance is increased in patients with obstructive sleep apnea (OSA). Because insulin resistance is an independent predictor of cardiovascular disease (CVD), this study was initiated to see if pioglitazone administration would improve insulin sensitivity and thereby decrease risk of CVD in overweight/obese, nondiabetic, insulin-resistant patients with untreated OSA. Patients (n = 30) were administered pioglitazone (45 mg/day) for 8 weeks, and measurements were made before and after intervention of insulin action (insulin-mediated glucose uptake by the insulin suppression test), C-reactive protein, lipid/lipoprotein profile, and gene expression profile of periumbilical subcutaneous fat tissue...

Creatinine clearance (CrCl) has been widely used to adjust the dosage of non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation (AF) and exclude contraindicated patients. However, there are few available real-world data on the relation between CrCl and adverse clinical outcomes in patients with AF. Therefore, we evaluated the clinical characteristics and adverse events in Japanese patients with AF stratified by CrCl. We categorized patients in the Fushimi AF Registry, a large prospective community-based Japanese cohort of patients with AF, into 3 groups as follows: (1) CrCl <30 ml/min, (2) CrCl 30 to 49 ml/min, and (3) CrCl ≥50 ml/min...

To assess the net impact of vital exhaustion on cardiovascular events and all-cause mortality, we conducted a systematic search of PubMed, EMBASE, and PsychINFO (through April 2016) to identify all studies which investigated the relation between vital exhaustion (VE) and health outcomes. Inclusion criteria were as follows: (1) a cohort study (prospective cohort or historical cohort) consisting of adults (>18 years); (2) at least 1 self-reported or interview-based assessment of VE or exhaustion; (3) evaluated the association between vital exhaustion or exhaustion and relevant outcomes; and (4) reported adjusted risk estimates of vital exhaustion/exhaustion for outcomes...

Coronary artery disease is common in patients with end-stage renal disease who are on hemodialysis. The efficacy and safety of evidence regarding the use of drug-eluting stents (DES) and bare-metal stents (BMS) in patients with dialysis is unclear. We searched MEDLINE, EMBASE, Science Citation Index, CINAHL, and the Cochrane CENTRAL database of controlled clinical trials for controlled trials that compare DES and BMS in dialysis patients up to June 2016. We conducted a meta-analysis across 14 eligible studies (n = 62,250 patients)...

Low-density lipoprotein cholesterol (LDL-C) has been demonstrated as an independent risk factor of ischemic stroke, but the association of LDL-C with ischemic stroke in patients with nonvalvular atrial fibrillation (AF) remains uncertain. Our objective was to explore whether LDL-C could refine stroke stratification in patients with AF. A total of 424 nonvalvular patients with AF with ischemic stroke and 391 ones without ischemic stroke were enrolled. No patient had received antithrombotic therapy. Multivariate logistic regression analysis showed that LDL-C was an independent predictor of ischemic stroke in patients with AF, with the adjusted odds ratio of 2...

Sarcopenia, defined as skeletal muscle loss and dysfunction, is attracting considerable attention as a novel risk factor for cardiovascular events. Although the loss of skeletal muscle is common in chronic kidney disease (CKD) patients, the relation between sarcopenia and cardiovascular events in CKD patients is not well defined. Therefore, we aimed to investigate the relation between skeletal muscle mass and major adverse cardiovascular events (MACE) in CKD patients. We enrolled 266 asymptomatic CKD patients (median estimated glomerular filtration rate: 36...

To understand the current impact of diabetes mellitus (DM) on long-term outcomes among patients referred for coronary angiography, we studied 14,337 consecutive patients (5,279 diabetic patients [37%]) referred to coronary angiography for assessment or treatment of coronary artery disease. We investigated long-term all-cause mortality and its interaction with hypoglycemic therapy and presenting coronary status. At baseline, patients with DM had more hypertension, hyperlipidemia, and renal failure; more were women, overweight, and more had previous coronary interventions...

Interatrial block (IAB) represents delay or block of conduction between the atria. IAB has been shown to predict the development or recurrence of atrial fibrillation (AF) in various clinical scenarios. Few studies have examined the correlation between coronary artery disease and the prevalence of IAB and its impact on AF. The aim of this study was to determine if specific coronary artery lesions (location and number) are associated with the presence of IAB and development of new-onset AF. Retrospective analysis of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) to our institution...

Pectus excavatum is one of the most common congenital chest wall deformities. The degree of sternal depression, which may result in compression of the right heart by the chest wall, is variable. While typically asymptomatic, there are various symptoms that can result from severe pectus excavatum. We report on a patient with severe pectus excavatum leading to dynamic obstruction of the right ventricular outflow tract in the seated position.

Troponin elevation is required to diagnose acute myocardial infarction (AMI), yet elevated values are often encountered in noncardiac disease states. We evaluated inpatient (IP) and outpatient (OP) encounters at 14 hospitals in calendar year 2014 and found that troponin assays were performed during 12% of all OP visits and 29% of all IP visits: 82,853 encounters in all. We employed an expert panel to estimate the likelihood of AMI based on primary International Statistical Classification of Diseases and Related Health Problems, 9th edition diagnoses...

Dysglycemia on admission is known to predict the prognosis of ST-segment elevation myocardial infarction (STEMI). Recently, hypoxic liver injury (HLI) has been proposed as a novel prognosticator for STEMI. We evaluated the prognostic impact of combined dysglycemia and HLI at the time of presentation in patients with STEMI who underwent primary percutaneous coronary intervention. From 2007 to 2014, 1,525 consecutive patients (79% men, mean age 61 years) who underwent primary percutaneous coronary intervention for STEMI in the INTERSTELLAR (Incheon-Bucheon Cohort of Patients Undergoing Primary PCI for Acute ST-Elevation Myocardial Infarction) cohort were analyzed retrospectively...

Ventricular premature complexes (VPCs) may represent a reversible cause of heart failure (HF); however, the type of patients most prone remains unknown. This study leverages a large population-based database to examine interactions that might prove clinically useful in risk-stratifying patients with VPCs. We used the California Healthcare Cost and Utilization Project to identify patients with VPCs and incident systolic HF from January 1, 2005, to December 31, 2009. We calculated hazard ratios for predictors of incident systolic HF using multivariable Cox proportional hazard models...

Left ventricular diastolic dysfunction in hypertrophic cardiomyopathy (HC) increases susceptibility to atrial fibrillation. Although phenotypical characteristics of the hypertrophied left ventricle are clear, left atrial (LA) and pulmonary venous (PV) remodeling has rarely been investigated. This study aimed to identify differences in LA and PV remodeling between HC and hypertensive heart disease (HHD) using 3-dimensional computed tomography. Included were 33 consecutive patients with HC, 25 with HHD, and 29 without any co-morbidities who were referred for catheter ablation of atrial fibrillation...
