Abstract:
Objective To evaluate the relationship between pressure derived fractional collateral flow (Q C/Q N) and left ventricular remodeling after acute myocardial infarction(AMI) Methods The Q C/Q N was measured in 21 patients with first AMI treated with percutaneous transluminal coronary angioplasty (PTCA), being determined by simultaneous measurement of mean aorta pressure (P a), distal coronary pressure (P w) during the balloon occlusion 21 patients were divided into two groups according to the value of Q C/Q N (group A, Q C/Q N≥0 25, group B, Q C/Q N0 05) At one month follow up, the difference in EF ( P 0 05) Both ESVI and EDVI were considerably increased in two groups Conclusion Angiographic Rentrop′s classification has its limitation in assessing the collateral circulation Q C/Q N is a major determinant of left ventricular remodeling and prognosis in patients with AMI
