Is adverse remodeling of the electrophysiological response to ischemia-reperfusion in human heart failure associated with remodeling of metabolic gene expression?
We demonstrate, for the first time in human hearts, that the electrophysiological response to ischemia-reperfusion in heart failure is accelerated during ischemia with slower recovery after reperfusion. This can enhance spatial conduction and repolarization gradients across the ischemic border and increase arrhythmia susceptibility. This adverse response was associated with downregulation of expression of cardiac metabolic genes.
The mean score in our study was 2.36, which is quite less as compared to reports from high income countries (range: 2.58-3.36). This study provides an insight on an aspect of burn care outcome, which can be reasonably expected in low income countries with the available standard of care. Being a female, presence of hand and face burn, requirement of corrective surgeries and inability to resume work were factors associated with poor QoL.
