Effect of peripheral artery disease on frequency, mortality and morbidity in patients of coronary artery

We were aimed to determine peripheral artery disease and risk factors and evaluate their effects on mortality and morbidity in patients who were decided to have coronary artery bypass graft operation due to coronary artery disease. We planned to enroll patients who have been decided to have a coronary artery bypass graft operation in the Department of Cardiovascular Surgery of Dokuz Eylul University Hospital, and the registration process has been completed between February 2019 and October 2020. In our study, coronary artery disease diagnosed by coronary angiography, coronary artery bypass grafting decision was made, no additional cardiac pathology accompanying coronary artery disease (heart valve disease, heart failure, congenital heart defects), renal functions within normal limits, patients without lung pathology were included. 99 patients, 22 (22.2%) female and 77 (77.8%) male patients, were recorded. It is planned to include individuals who are at least 50 years old. The average age of the patients was 64.45 ± 7.75 years; distribution is 50-88 years, median is 64 years. Ankle-brachial index (ABI) was measured in all patients included in the study and risk factors were investigated. In addition, past laboratory and imaging histories of the patients were also examined and data were recorded as LDL, glucose, creatinine, ejection fraction (EF), bypassed coronary arteries, operation values, the percentage of stenosis in the coronary arteries, pre- and post-operative hospitalization periods in the hospital. Ankle-brachial index: While the patient was at rest, blood pressure was measured over the radial or ulnar artery in the bilateral upper extremities and over the dorsal pedal artery or posterior tibial artery in the lower extremities using a standard blood pressure cuff and sound doppler. The ankle-brachial index value was calculated with the ratio of the highest systolic pressure to the highest arm pressure value of the ankle. In our study, the presence of PAD on mortality was not found to be statistically sigificant in our patients who underwent CABG. However, the absence of PAD increased survival in patientes undergoin coronary artery bypass. The absence of carotid artery disease also increased survival in our patients who underwent CABG, while the presence of carotid artery disease increased mortality. In CABG applied cases; we think that this patient group should be followed up closely and medical treatment should be applied because of the negative effect of presence of PAH on long-term mortality.
