Relationship between myocardial metabolites and contractile abnormalities during graded regional ischemia. Phosphorus-31 nuclear magnetic resonance studies of porcine myocardium in vivo. [PDF]

Journal of Clinical Investigation, 1990
The mechanisms responsible for changes in myocardial contractility during regional ischemia are unknown. Since changes in high-energy phosphates during ischemia are sensitive to reductions in myocardial blood flow, it was hypothesized that myocardial function under steady-state conditions of graded regional ischemia is closely related to changes in ...

Coronary Artery Disease and Intradialytic Myocardial Ischemia in Hemodialysis: An Exploratory Study Using Intradialytic Imaging [PDF]

Kidney Medicine
Rationale & Objective: Recurrent segmental myocardial ischemia (myocardial stunning) is a well-recognized consequence of hemodialysis leading to fixed contractile deficits and increased morbidity and cardiac mortality.

Quantification of Cardiac Kinetic Energy and Its Changes During Transmural Myocardial Infarction Assessed by Multi-Dimensional Seismocardiography

Frontiers in Cardiovascular Medicine, 2021
Introduction: Seismocardiography (SCG) records cardiac and blood-induced motions transmitted to the chest surface as vibratory phenomena. Evidences demonstrate that acute myocardial ischemia (AMI) profoundly affects the SCG signals.

Blunting of Colon Contractions in Diabetics with Gastroparesis Quantified by Wireless Motility Capsule Methods. [PDF]

PLoS ONE, 2015
Generalized gut transit abnormalities are observed in some diabetics with gastroparesis. Relations of gastric emptying abnormalities to colon contractile dysfunction are poorly characterized.

Aerobic Training in Patients with Congenital Myopathy. [PDF]

PLoS ONE, 2016
INTRODUCTION:Congenital myopathies (CM) often affect contractile proteins of the sarcomere, which could render patients susceptible to exercise-induced muscle damage. We investigated if exercise is safe and beneficial in patients with CM.

Induction of PGC-1α expression can be detected in blood samples of patients with ST-segment elevation acute myocardial infarction. [PDF]

PLoS ONE, 2011
Following acute myocardial infarction (MI), cardiomyocyte survival depends on its mitochondrial oxidative capacity. Cell death is normally followed by activation of the immune system.

The new clinical standard of integrated quadruple stress echocardiography with ABCD protocol

Cardiovascular Ultrasound, 2018
Background The detection of regional wall motion abnormalities is the cornerstone of stress echocardiography. Today, stress echo shows increasing trends of utilization due to growing concerns for radiation risk, higher cost and stronger environmental ...

Alterações contráteis segmentares e sua associação com arritmias ventriculares complexas, em pacientes chagásicos com eletrocardiograma normal ou borderline Regional left ventricular dysfunction and its association with complex ventricular arrhythmia, in chagasic patients with normal or borderline electrocardiogram

Revista da Sociedade Brasileira de Medicina Tropical, 2010
INTRODUÇÃO: Morte súbita representa a principal causa de óbito em chagásicos. Eventos fatais em pacientes saudáveis, com anormalidades contráteis, foram documentados.
