Aims: Delayed QRS transition zone in the precordial leads of the 12-lead electrocardiogram (ECG) has been recently associated with increased risk of sudden cardiac death (SCD), but the underlying mechanisms are unknown. We correlated echocardiographic findings with ECG and clinical characteristics to investigate how alterations in cardiac structure and function contribute to this risk marker. Methods and Results: From the ongoing population-based Oregon Sudden Unexpected Death Study (catchment population ∼1 million), SCD cases with prior ECG available (n = 627) were compared with controls (n = 801)...

Aims: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease mainly caused by desmosome gene mutations. The genetic culprit, however, remains elusive in ∼50% of ARVC patients. One of the reasons for missing genetic abnormalities is the difficulty in detecting large deletions/duplications, which are called as copy number variation (CNV) by the Sanger sequencing method. This study aimed to identify CNVs in PKP2 and a part of other desmosome genes in ARVC patients. Methods and Results: The study cohort consisted of 71 ARVC probands who were diagnosed as definite or borderline cases based on 2010 Task Force Criteria...

OBJECTIVE: Myocardial apoptosis is an important pathologic basis of ischemia-reperfusion injury (I/R). Transforming growth factor β1 (TGFβ1) participates in the regulation of oxidative damage and apoptosis. TGFβ1 is upregulated in the repair process of I/R injury. It is speculated that TGFβ1 over-expression is involved in the endogenous protective mechanism of I/R injury. This study explores the significance of TGFβ1 in myocardial cell apoptosis after I/R. MATERIALS AND METHODS: Rat myocardial I/R injury model was established...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary artery irregularity. This study aimed to clarify the long-term postoperative outcomes in ALCAPA patients, and to compare the infantile and adult types. METHODS: We retrospectively analyzed the clinical data from 33 patients with ALCAPA who underwent surgical repairs after 1980. The patients were grouped based on whether presentation occurred before (infantile type: n=14) or after (adult type: n=19) 1 year of age...

BACKGROUND: High level of androgens found in congenital adrenal hyperplasia (CAH) seems to have a deleterious effect on heart function. We therefore evaluate cardiac function of children with CAH in comparison with a healthy group. METHODS: We carried out a case-control study in the single endocrinology unit of the Mother and Child Center of Chantal Biya's Foundation. Cases were matched for age and genotypic sex to 2 healthy controls. We analyzed the ejection fraction (LVEF), fractional shortening and left ventricular mass; output and cardiac index; E and A waves velocities, E/A ratio and the mitral deceleration time and diameter of the left atrium; tricuspid annular plane systolic excursion and pulmonary artery systolic pressure were also measured...

Aims: The incidence and predictors of stroke in patients with heart failure and preserved ejection fraction (HF-PEF), but without atrial fibrillation (AF), are unknown. We described the incidence of stroke in HF-PEF patients with and without AF and predictors of stroke in those without AF. Methods and results: We pooled data from the CHARM-Preserved and I-Preserve trials. Using Cox regression, we derived a model for stroke in patients without AF in this cohort and compared its performance with a published model in heart failure patients with reduced ejection fraction (HF-REF)-predictive variables: age, body mass index, New York Heart Association class, history of stroke, and insulin-treated diabetes...

BACKGROUND: Evaluation of impaired left ventricular (LV) filling has focused on intrinsic causes of LV dysfunction; however, pulmonary vascular changes may contribute to reduced LV filling and dyspnea. We hypothesized that lower total pulmonary vascular volume (TPVV) on computed tomography (CT) would be associated with dyspnea and decrements in LV end-diastolic volume, particularly among ever-smokers. METHODS: The Multi-Ethnic Study of Atherosclerosis recruited adults without clinical cardiovascular disease in 2000-02...

BACKGROUND/AIM: Aortic valve sclerosis (AVS) is characterized by lipid deposition and calcific infiltration on the edge of aortic leaflets without significant restriction of motion. The SYNTAX Score (SS) is an important method for evaluating coronary artery disease (CAD). Many studies showed that there is an important relation between the SS and undesired cardiac outcomes. In our study, we investigated the correlation between the SS and AVS by including both ACS and stable CAD cases. MATERIALS AND METHODS: We enrolled 543 patients with CAD who underwent coronary angiography into this cross-sectional study between September 2013 and September 2014...
