Contemporary NSTEMI management: the role of the hospitalist. [PDF]

, 2019
Non-ST-segment elevation myocardial infarction (NSTEMI) is defined as elevated cardiac biomarkers of necrosis in the absence of persistent ST-segment elevation in the setting of anginal symptoms or other acute event.

Metformin for non-diabetic patients with coronary heart disease (the CAMERA study): a randomised controlled trial [PDF]

, 2009
<br>Background: Metformin reduces cardiovascular risk in patients with type 2 diabetes seemingly independent of lowering blood glucose concentration. We assessed the cardiovascular effects of metformin in individuals without type 2 diabetes.</br&

Size‐Modulated Mesoderm‐Endoderm Divergence and Myocardial Cavitation in Micropatterned Cardioids

Advanced Science, EarlyView.
Micropatterned cardioids, CRISPR‐engineered reporter hiPSCs, deep‐tissue imaging, and single‐cell RNA sequencing are integrated to model mesoderm‐endoderm co‐development. Heart‐foregut crosstalk promotes single large cavitation inside cardioids, resembling early heart chamber formation. ABSTRACT The human heart, originating from the splanchnic mesoderm,

Amino Acid Changes at Arginine 204 of Troponin I Result in Increased Calcium Sensitivity of Force Development. [PDF]

, 2016
Mutations in human cardiac troponin I (cTnI) have been associated with restrictive, dilated, and hypertrophic cardiomyopathies. The most commonly occurring residue on cTnI associated with familial hypertrophic cardiomyopathy (FHC) is arginine (R), which ...

3D Bioprinted Fat‐Myocardium Model Unravels the Role of Adipocyte Hypertrophy in Atrial Dysfunction

Advanced Science, EarlyView.
A human‐derived 3D bioprinted fat–myocardium model is developed to investigate how adipocyte hypertrophy drives atrial dysfunction in obesity. Palmitate‐induced adipocyte hypertrophy promotes adipose dysfunction that impairs atrial cardiomyocyte metabolism and electrophysiology through both paracrine and direct interactions. This platform recapitulates

A8V Mutation of Cardiac Troponin C Enhances Troponin I Binding [PDF]

Biophysical Journal, 2016
We find in our model that higher affinity for TnI is a potential mechanism by which the A8V mutation renders troponin-C (TnC) capable of causing hypertrophy in hearts carrying TnCA8V. At issue is to explain how muscle fibers reconstituted with TnCA8V are sensitized to Ca2+, i.e.

Cardiac troponin I as compared to troponin T for the detection of myocardial damage in horses [PDF]

, 2015
Background: Different cardiac troponin I (cTnI) assays give different results. Only 1 manufacturer has marketed troponin T (cTnT) assays. Therefore, cTnT often is preferred for detection of myocardial infarction in human patients.

F‐Box and Leucine‐Rich Repeat Protein 4 (FBXL4) Maintains Sarcomere Integrity and Cardiac Function by Enhancing K48‐Linked Ubiquitinated Degradation of Profilin‐1 (PFN1)

Advanced Science, EarlyView.
Schematic diagram depicting the proposed signaling mechanisms underlying the effects of FBXL4 in the setting of cardiac hypertrophy. Under hypertrophic stimulation, cardiomyocytes‐specific overexpression FBXL4 maintains sarcomere integrity and cardiac function by enhancing K48‐linked ubiquitinated degradation of PFN1 at the K70 site.

Study of Plasma Malondialdehyde, Troponin I and C - Reactive protein in Acute Coronary Syndromes Patients

پزشکی بالینی ابن سینا, 2006
Introduction & Objective: Ischemic injury of endothelium is associated with prostaglandin synthesis and platelet adhesion and aggregation, which may be associated with the release of aldehydes such as malondialdehyde (MDA). C-reactive protein and cardiac

Effect of antioxidant supplementation on exercise-induced cardiac troponin release in cyclists: a randomized trial. [PDF]

PLoS ONE, 2013
Cardiac troponin is the biochemical gold standard to diagnose acute myocardial infarction. Interestingly however, elevated cardiac troponin concentrations are also frequently observed during and after endurance-type exercise.
