Abstract
This study was done to evaluate the effect of coronary lesion length on non-diabetic patients’ mid-term (6 months) outcomes. Thirty (30) patients from Alexandria Main University Hospital underwent history-taking with emphasis on risk factors for coronary heart disease (CHD) and complete physical examination. Laboratory investigations done for the patients included blood urea, serum creatinine, fasting and post-prandial blood glucose, total cholesterol, serum triglycerides, bleeding and coagulation times, prothrombin activity and complete blood count. Standard 12-lead ECG was done as a baseline, 24-hours after stenting and whenever clinically indicated. Echocardiography was done to estimate the left ventricular ejection fraction (LVEF). Coronary angiography was done at the time of BMS placement (baseline) and whenever clinically indicated. Patients were followed-up for six-month with emphasis on the occurrence of angina and MACE (death, acute coronary syndromes and target vessel revascularization (TVR)).
In our study, mean age of the patients was 56.07 ± 9.37 years. Male patients accounted for 73.33% of the studied group. Smokers and ex-smokers accounted for 56.67% of the patients. Hypertensive patients accounted for 50% of the studied group. Dyslipidemia was found in 26.67% of patients. Mean LVEF was 53.47 ± 6.26%. The number of stents per patient was 1 to 3 stents. Stent length was 31 ± 7.89 mm while stent diameter was 3.23 ± 0.25 mm. At 6 months follow-up, cardiac death occurred in 10% of patients while TVR occurred in 13.33% of patients. Angina (CCS class II) occurred in 13.33% of patients while in-stent narrowing less than 50% necessitating only medical treatment occurred in 13.33% of patients. Asymptomatic patients represented 40% of the studied group.
