Improvement in left ventricular function following successful rescue percutaneous coronary intervention is independent of time-to-reperfusion.

Objective: To study the influence of clinical and angiographic factors on global and regional left ventricular (LV) function after rescue percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI).

Methods: We performed repeat cardiac catheterization in 102 patients who underwent rescue PCI at our centre. Eighty-two patients had suitable baseline and follow-up ventriculograms, which were analyzed offline by an automated edge detection technique.
