What was the improved ejection fraction in the ischemic cardiomyopathy case?

Explanation:
In ischemic cardiomyopathy, the ejection fraction (EF) shows how much blood the left ventricle pumps out with each beat, and it can improve when viable myocardium is revascularized or when medical therapy reverses remodeling. An EF of 55% falls in the normal-to-near-normal range, indicating substantial recovery of systolic function after treatment. That level of improvement aligns with the scenario described, where the heart’s pumping efficiency increases from a reduced baseline toward normal. The other numbers would indicate less improvement (40% still shows dysfunction) or higher EF values that are harder to achieve consistently after ischemic injury, making 55% the best reflection of the reported improvement.
