Input: Question: Does blood PGC-1 Concentration predict Myocardial Salvage and Ventricular Remodeling After ST-segment Elevation Acute Myocardial Infarction?
Answer: Baseline PGC-1 expression and an attenuated systemic response after acute myocardial infarction are associated with greater myocardial salvage and predict less ventricular remodeling.
Output:
yes
