Inferior ST-Elevation Myocardial Infarction Associated with Takotsubo Cardiomyopathy

Case Reports in Medicine, 2010
Takotsubo cardiomyopathy (TCM) is usually characterized by transient left ventricular apical ballooning. Due to the clinical symptoms which include chest pain, electrocardiographic changes, and elevated myocardial markers, Takotsubo cardiomyopathy is ...

Sevoflurane Pre-conditioning Ameliorates Diabetic Myocardial Ischemia/Reperfusion Injury Via Differential Regulation of p38 and ERK. [PDF]

, 2020
Diabetes mellitus (DM) significantly increases myocardial ischemia/reperfusion (MI/R) injury. During DM, cardioprotection induced by conventional pre-conditioning (PreCon) is decreased due to impaired AMP-activated protein kinase (AMPK) signaling.

Left ventricular active stiffness: dependency on time and inotropic state [PDF]

, 1978
Left ventricular systolic stiffness was measured by rapidly changing ventricular volume (within 7 ms) of isovolumically contracting isolated rabbit hearts. Instantaneous pressure-volume relations were found to be linear with slopes that depended upon the

New Aspects for the Treatment of Cardiac Diseases Based on the Diversity of Functional Controls on Cardiac Muscles: Diversity in the Excitation–Contraction Mechanisms of the Heart

Journal of Pharmacological Sciences, 2009
The waveform of the myocardial action potential (AP) triggering contraction differs among the species, developmental stage, and pathological state. The species difference in heart rate, which inversely correlates with body size, originates in the ion ...

Index of Myocardial Performance risk assessment by Ultrasound Waves of patients with high blood pressure

Diyala Journal of Medicine, 2018
Background: It is well known that hypertension results in cardiac overload. This overload is more profound on the left ventricle were systolic high pressure is present resulting in stiff LV.

The Effect of Ivabradine on the Human Atrial Myocardial Contractility in an In Vitro Study

Cardiology Research and Practice, 2019
Purpose. Ivabradine has emerged as a new antiarrhythmic agent that could compete with the traditional ones, such as beta-blockers. This experimental study aims to ascertain whether ivabradine directly interferes with the myocardial contractility in an in

Ischemic preconditioning affects phosphosites and accentuates myocardial stunning while reducing infarction size in rats

Frontiers in Cardiovascular Medicine
Background and aimsIschemic preconditioning (IPC), i.e., brief periods of ischemia, protect the heart from subsequent prolonged ischemic injury, and reduces infarction size. Myocardial stunning refers to transient loss of contractility in the heart after
