Treatment with antioxidant vitamins has been found to improve myocardial contraction
and relaxation defects in septic animals as a consequence of alleviated inflammatory response and apoptosis .
NNBP also strengthens myocardial tissue perfusion through its squeezing effect of myocardial contraction
on coronary arterial and venous systems.
Transthoracic echocardiography (TTE) revealed moderately enlarged left atrium (LA) with slight reduction of left ventricular myocardial contraction
, mild pericardial effusion, and normal left ventricular ejection fraction of 50%.
ISO causes exaggerated [Ca.sup.2+] influx, increased myocardial contraction
, oxygen demand, leading to depletion of ATP and electron leakage from the respiratory chain.
The cardiac MRI is used to determine myocardial contraction
(Okeke et al., 2013).
