Resumen:
Cardiovascular indices are useful to evaluate myocardial damage and the effectiveness of medical interventions during ischemic heart failure.Left ventricular thickening has been used to evaluate myocardial ischemia generated by transitory induced coro-nary occlusion. Ischemic alterations can be quantified using the wall thickening fraction (WTF). Likewise, the augmentation index (AIx) is used to esti-mate the elasticity of an artery by observing the influence of incident and reflected waveforms in the systolic aortic pressure.WTF and the AIx indices were calculated using data ob-tained from an animal model with induced heart failure and transient myocardial ischemia, followed and a reperfusion stage. The relationship between both indices was analyzed.The analysis of the relationship between WTF and AIx during heart failure and reperfusion stage showed: a) a posi-tive correlation in six animals (p
