Effect of propranolol on regional myocardial function in anesthetized open-chest dogs with myocardial ischemia [PDF]

, 1978
Effects of propranolol on ischemic segmental function were studied in anesthetized open-chest dogs. Two segment-length gauges were used for measuring the regional myocardial function: one was sutured on to the left ventricular surface perfused by the ...

Exercise training corrects control of spontaneous calcium waves in hearts from myocardial infarction heart failure rats [PDF]

, 2011
Impaired cardiac control of intracellular diastolic Ca²⁺ gives rise to arrhythmias. Whereas exercise training corrects abnormal cyclic Ca²⁺ handling in heart failure, the effect on diastolic Ca<sup>2 ...

Studies on myocardial contraction. Right ventricular contraction and local myocardial contraction measured by the transcatheter method.

The Keio journal of medicine, 1969
The relations between the right ventricular contraction and the local myo-cardial shortening measured by means of the transcatheter method were dis-cussed. The local tension-velocity-length relationships were also shown.The authors wish to express their sincere gratitude to Prof. H. Sasamoto for his generous guidance and instruction in this study.

The impact of myocardial compressibility on organ-level simulations of the normal and infarcted heart

Scientific Reports, 2021
Myocardial infarction (MI) rapidly impairs cardiac contractile function and instigates maladaptive remodeling leading to heart failure. Patient-specific models are a maturing technology for developing and determining therapeutic modalities for MI that ...

A comparative study of embedded and anesthetized zebrafish in vivo on myocardiac calcium oscillation and heart muscle contraction

Frontiers in Pharmacology, 2010
The zebrafish (Danio rerio) has been used as a model for studying vertebrate development in the cardiovascular system. In order to monitor heart contraction and cytosolic calcium oscillations, fish were either embedded in methylcellulose or anesthetized

Effects of Rosuvastatin and Pitavastatin on Ischemia-Induced Myocardial Stunning in Dogs

Journal of Pharmacological Sciences, 2008
Incomplete recovery of myocardial contraction after reperfusion following brief ischemia is called the “stunning phenomenon” in an animal experiment.

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]

, 2005
Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.

Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricle

Cardiovascular Ultrasound, 2006
Background The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering ...

Effects of Short Term Adiponectin Receptor Agonism on Cardiac Function and Energetics in Diabetic db/db Mice

Journal of Lipid and Atherosclerosis, 2022
Objective Impaired cardiac efficiency is a hallmark of diabetic cardiomyopathy in models of type 2 diabetes. Adiponectin receptor 1 (AdipoR1) deficiency impairs cardiac efficiency in non-diabetic mice, suggesting that hypoadiponectinemia in type 2 ...
