Evaluation Of Ankle Brachial Index As A Predictive Factor For Diagnosis Of Coronary Artery Disease
E Nematipor , B Heydari,
Volume 64, Issue 1 (3-2006)
Abstract

Background and Aim: Cardiovascular disease is one of the main causes of mortality and morbidity around the world and because of insidious and chronic progression of arterioscleroses and coronary artery disease (CAD) and also correlation between peripheral arterial disease and CAD we evaluated ankle brachial index (ABI) as a predictive factor for early diagnosis of CAD.

Materials and Methods: Evaluation of ABI performed in patients who referred to cardiology department of Imam Khomeini Hospital for coronary angiography from April 2003 to May 2004. 100 patients selected for the study, 50 patients with CAD (at least one vessel significantly involved) and 50 patients with normal coronary arteries as control cases. Relation between ABI and CAD studied in the patients, also other variables such as age, sex, family history of CAD, diabetes mellitus, hypertension, hyperlipidemia, cigarette smoking and claudication were evaluated.

Results: The mean age in patients with coronary artery disease was 56±16 years old (66% male, 34% female) and in normal coronary patients was 52+15 years old (48% male, 52% female). The mean ABI in patients with abnormal coronary arteries was 1.07±0.028 and in cases with normal coronary arteries was 1.12±0.016 that was not significant (P= 0.128). In addition there was no significant value between ABI and other variables mentioned above. All patients with ABI≤ 0.9 (14% of patients) had CAD.

Conclusion: This study revealed that although an ABI≤ 0.9 has a high predictive value for CAD, the ABI itself can not be a sensitive predictor of CAD diagnosis because a large numbers of CAD patients had ABI more than 0.9. Hence this level of ABI can not rule out the presence of CAD in many patients.

Abstract
Background: smoking enhances the risk of cardiac events in patients with coronary artery disease. So, it is necessary to evaluate the effects of exercise-based cardiac rehabilitation on endothelial function and functional capacity among smoker patients.
Methods: This randomized clinical trial study was conducted on 56 non-diabetic smokers with a history of percutaneous coronary intervention or coronary artery bypass graft surgery in Imam Khomeini Hospital from May to August 2015. Based on cardiac rehabilitation, patients were divided into intervention and control groups. Before rehabilitation, fasting blood sugar (FBS), lipid profile (LDL, HDL, triglyceride, and total cholesterol), and Ankle-Brachial Index (ABI) were measured for endothelial function. Besides, METs were measured based on the Duke activity status index. After 24 rehabilitation sessions (3 sessions of 1 hour each week for 2 months), all values were checked again and compared with the initial values.
Results: The mean age of the subjects in the cardiac rehabilitation and control groups were 61.18 and 52.32, respectively. Before the intervention, there were no significant differences between the two groups in terms of the ABI variables, BMI, systolic and diastolic blood pressure, LDL, triglyceride, total cholesterol and FBS; only HDL and  METs showed significant differences. After exercise-based cardiac rehabilitation, the mean rate of ABI changes was +0.078 on the right side of the body and +0.084 on the left side of the body. In the control group, these values were 0.002 and 0.003, respectively (P=0.001). The amount of changes in increasing METs as well as decreasing body mass index (BMI), and systolic and diastolic blood pressure in the rehabilitation group were statistically significant compared to the control group. In addition, there were no significant differences in terms of FBS and lipid profiles either (P>0.05).
Conclusion: Two months of cardiac rehabilitation with regular exercise was associated with improved ABI as an indicator of endothelial function and prognosis of cardiovascular disease, as well as improved cardiac functional capacity among smoker patients.
