Prognostic Value of The Age, Creatinine, and Ejection Fraction Score for Non-infarct-related Chronic Total Occlusion Revascularization After Primary Percutaneous Intervention in Acute ST-elevation Myocardial Infarction Patients: A Retrospective Study
Prognostic Value of The Age, Creatinine, and Ejection Fraction Score for Non-infarct-related Chronic Total Occlusion Revascularization After Primary Percutaneous Intervention in Acute ST-elevation Myocardial Infarction Patients: A Retrospective Study
The age, creatinine, and ejection fraction (ACEF) score has been used to evaluate the
 clinical prognostic to patients who underwent PCI. However, it is not known if ACEF score
 could evaluate the prognostic of recanalization of non-infarct-related coronary arteries
 (non-IRA) chronic total occlusions (CTO) in patients who successful underwent primary PCI.
 The objectivity of current study was to assess the prognostic value of ACEF score in acute
 ST-segment elevation myocardial infarction (STEMI) patients with non-IRA CTO after successful
 primary PCI.
Among the 2952 patients with STEMI successful treatment by PCI, 395 patients (13.4%) had a
 non-IRA CTO lesion. 18 patients were excluded from current study as they death within 7
 days (n=6) or were not to follow-up (n=7). Due to unavailability of ejection fraction or
 renal function before CTO-PCI, ACEF score could not be calculated in 5 patients. The
 remaining 377 patients (95.4%) were finally analyzed in the study. 279 patients performed a
 staged CTO-PCI attempt(ranging 7-28 days) and was successful in 221 of them. Due to low
 possibility of PCI success or patients refused to perform PCI, 98 patients did not undergo
 the PCI attempt. The patients were then divided into successful CTO-PCI group (221
 patients) and failed/ non-attempted CTO-PCI group (156 patients).
