In this study the intrinsic rate and ventricular contractile force were measured in dogs during acute heart failure produced by agents which impair myocardial energy syntinesis ... were consistent ...

Mechanisms accounting for in vivo inotropic effects of NO include parasympathetic and sympathetic outflow to the heart, myocardial cholinergic and adrenergic receptor-effector coupling, myocardial ...

U-II was found to increase afterload and reduce myocardial contractility. Its effect at high concentrations is best rationalized by myocardial ischemia. Using the calculations of Sunagawa et al.

Specifically, before revascularization, 804 of 2,093 myocardial segments analyzed (38%) had abnormal contractility, and 694 segments (33%) had some areas of hyperenhancement. Among all 804 ...

Peptides have emerged as a focal point in molecular and biological research, providing a promising avenue for understanding ...

Non-ischaemic causes include myocarditis, end-stage cardiomyopathy or sustained arrhythmias. Cardiogenic shock after STEMI is mostly a consequence of decreased myocardial contractility due to the ...

Sepsis-induced myocardial dysfunction (SIMD) involves reversible myocardial dysfunction ... and enhanced calcium handling to improve contractility, and harmful effects (red lines) via CaMKII-mediated ...

Conclusions Patients with unoperated congenitally corrected TGA have a high prevalence of myocardial perfusion defects, with consequent abnormalities of regional wall motion and thickening, and ...

Nevertheless, the excellent reproducibility of Paw tw suggests that it may be a useful means of monitoring inspiratory muscle contractility in the routine care of mechanically ventilated patients.

Background —Patients with spinal cord injury (SCI) have an increased prevalence of gallstones. Aims —To study prospectively the incidence of gallstones and gall bladder contractility in patients with ...

This finding may be explained by suboptimal sarcomere length due to lower end-diastolic volumes, impairing myocardial contractility as indicated by reduced E CC. Additionally, as a critical ...
