Evaluation of short-term (in-hospital) and long-term (6 months and one year) clinical results of patients with PCI on vein grafts referred to Shahid Rajaei Cardiovascular Hospital in 2017 to 2019

Revascularization to treat coronary artery stenosis in two ways; Percutaneous intervention (PCI) and open surgery can be performed.For patients who were previously treated with open surgery and now have symptoms again, due to the higher mortality and morbidity of re-surgery, PCI is the preferred method of treatment.

This study is a cohort.The study population includes all patients without exit criteria who were subjected to PCI on SVG in Shahid Rajaei Hospital from October 2017 to 2019. In these patients, the short-term(in-hospital) and long-term(6 months and one year) clinical results were examined in terms of the incidence of MACE(major adverse cardiovascular events).

216 patients aged 39 to 99 years with an average of 65.95±9.16 were included in the study. In-hospital MACE, we had only one case of stroke, one case of MI, and one case of vascular complications. During the first 6 months, there were 19 cases of mortality, 5 cases of MI, 2 cases requiring reperfusion on the same SVG, and 3 cases requiring PCI, It was seen on other SVGs of the patients. After one year, a total of 28 cases of mortality, 13 cases of MI, 7 cases requiring re-establishment of flow in the same SVG and 7 cases requiring PCI were seen on other SVGs of the patients. The relationship between the incidence of MACE with the age and chronic kidney disease was seen.

MACE occurred more in older patients and patients with a history of chronic kidney disease with GFR>30 (mild and moderate CKD).
