The objective of this study was to identify unknown modulators of Calcineurin (Cn)-NFAT signaling. Measurement of NFAT reporter driven luciferase activity was therefore utilized to screen a human cardiac cDNA-library (~10(7) primary clones) in C2C12 cells through serial dilutions until single clones could be identified. This extensive screening strategy culminated in the identification of SUMO2 as a most efficient Cn-NFAT activator. SUMO2-mediated activation of Cn-NFAT signaling in cardiomyocytes translated into a hypertrophic phenotype...

Introduction The significance of abnormal cardiac measures in asymptomatic females who harbor dystrophin gene mutations is controversial. Methods Echo-measures of ventricular function were compared with published norms in a cross-sectional study of 130 (age 39 ± 15.7 years) 'carriers' of Duchenne or Becker muscular dystrophy (DBMD). Correlations between cardiomyopathy (CM) and mutation, CK levels, age, and muscle symptoms were investigated. Results Depending on definition, CM prevalence was 3-33%. Ejection fraction (Simpson) was < 55% in 9 (13%) and < 40% in 2 (2...

In 1992, the Brugada syndrome (BrS) was recognized as a disease responsible for sudden cardiac death, characterized by a right bundle-branch block with ST segment elevation in the leads V1 and V2. This syndrome is highly associated with sudden cardiac death, especially in young males. BrS is currently diagnosed in patients with ST-segment elevation showing type 1 morphology ≥ 2 mm in ≥1 leads among the right precordial leads V1 or V2 positioned in the 2nd, 3rd, or 4th intercostal space, and occurring either spontaneously or after a provocative drug test by the intravenous administration of Class I antiarrhythmic drugs...

Using time-resolved fluorescence resonance energy transfer (FRET), we have developed and validated the first high-throughput screening (HTS) method to discover compounds that modulate an intracellular Ca(2+) channel, the ryanodine receptor (RyR), for therapeutic applications. Intracellular Ca(2+) regulation is critical for striated muscle function, and RyR is a central player. At resting [Ca(2+)], an increased propensity of channel opening due to RyR dysregulation is associated with severe cardiac and skeletal myopathies, diabetes, and neurological disorders...

Left-ventricular outflow tract obstructions (LVOTO) encompass a wide spectrum of phenotypically heterogeneous heart malformations which frequently cluster in families. We performed family based whole-exome and targeted re-sequencing on 182 individuals from 51 families with multiple affected members. Central to our approach is the family unit which serves as a reference to identify causal genotype-phenotype correlations. Screening a multitude of 10 overlapping phenotypes revealed disease associated and co-segregating variants in 12 families...

BACKGROUND: Multiple studies have sought to determine variables associated with improved "response" to cardiac resynchronization therapy(CRT). Such variables, however, are often derived from inadequately controlled, single center cohort studies calling external validity into question. We sought to determine predictors of response to CRT-D and CRT-P utilizing the methods of systematic review. METHODS: We searched MEDLINE, Embase®, and the Cochrane Central Register of Controlled Trials (CENTRAL) from January 1, 1995, as this is the date of first article reporting use of CRT through October 20, 2014...

OBJECTIVE: Childhood adversity is a vulnerability factor for chronic pain. However, the underlying pain mechanisms influenced by childhood adversity remain unknown. The aim of the current study was to evaluate the impact of childhood adversity on dynamic pain sensitivity in young adults. METHODS: After screening for childhood adverse events and health status, healthy individuals reporting low (below median; n = 75) or high levels of adversity (the top 5%; n = 51) were invited for pain testing...

OBJECTIVE: The traditional history and physical (H&P) is a poor screening modality to identify athletes at risk for sudden cardiac death. Although better than H&P alone, electrocardiograms (ECG) have also been found to have high false-positive rates. A limited portable ECG by a frontline physician (PEFP) performed during preparticipation physical examination (PPE) allows for direct measurements of the heart to more accurately identify athletes with structural abnormalities. Therefore, it is worthwhile to assess the feasibility of incorporating limited PEFP as part of PPEs...

5-Fluorouracil (5-FU) is the backbone of the chemotherapy regimens approved for treatment of many malignancies, especially colorectal cancer (CRC). The incidence of cardiotoxicity associated with 5-FU ranges between 1.5% to 18% and is most commonly manifested as anginal symptoms. Cardiomyopathy is very rarely reported with 5-FU and capecitabine. A 35-year-old Caucasian male with T3, N1, M0 rectal cancer after the initial neoadjuvant chemoradiation with 5FU/LV followed by surgical abdominoperineal resection (APR), began mFOLFOX6 in the adjuvant setting...

We report a 55-year-old man who underwent off-pump bypass surgery and had diffuse oozing and bruising postoperatively. His hematological profile had been normal preoperatively and he had been off antiplatelets for a week prior to surgery. Postoperatively, a detailed talk revealed that he had been on dietary supplements containing fish oil and garlic - both of which are known to affect platelet function. It behooves the surgeon and anesthetist to screen all patients preoperatively for the possibility of intake of any dietary supplements taken by the patient...

Human pluripotent stem cell (hPSC)-derived cardiomyocytes hold great potential for in vitro modeling of diseases like cardiomyopathies. Yet, knowledge about expression and functional impact of sarcomeric protein isoforms like the myosin heavy chain (MyHC) in hPSC-cardiomyocytes is scarce. We hypothesized that ventricular β-MyHC expression alters contraction and calcium kinetics and drives morphological and electrophysiological differentiation towards ventricular-like cardiomyocytes. To address this, we (1) generated human embryonic stem cell-derived cardiomyocytes (hESC-CMs) that switched towards exclusive β-MyHC, and (2) functionally and morphologically characterized these hESC-CMs at the single-cell level...

Wolff Parkinson White (WPW) syndrome is a condition in which there is an aberrant conduction pathway between the atria and ventricles, resulting in tachycardia. A 42-year-old patient, who was treated for WPW syndrome previously, presented with chronic somatic pain. With her cardiac condition in mind, she was thoroughly worked up for a recurrence of disease. As part of routine screening of all patients at our pain clinic, she was found to have severe depression as per the Patient Health Questionnaire-9 (PHQ-9) criteria...
