Korelasi antara Ankle-Brachial Index, Pulse Oximetry, dan Ankle Peak Systolic Velocity Penderita Diabetes Melitus tanpa Obesitas Abdominal

Abstract

Background: Diabetes Mellitus is the most common complication of vascular complications, one of which is peripheral arterial disease (PAD), which can increase morbidity and mortality in diabetic patient.Early screening parameter and diagnosis of PAD that currently still largely accepted are Ankle-Brachial Index (ABI) and pulse oximetry. ABI and pulse oximetry each has advantages and disadvantages. Patients with diabetes, especially if accompanied by abdominal obesity often have arterial sti?ness so that the value of ABI actually increased, in this case pulse oximetry has a higher sensitivity. Ankle Peak Systolic Velocity (APSV) which is the average of Peak Systolic Velocity (PSV) of anterior and posterior tibial artery at ankle joint level is a new parameter for assessing ischemia of the lower limb and is not in?uenced by arterial sti?ness. The purpose of this study was to determine and analyze the correlation between ankle-brachial index, pulse oximetry and ankle peak systolic velocity in DM patients without abdominal obesity.Materials and methods: This study was observational analytic with cross-sectional design study in subjects with DM without abdominal obesity who meet the inclusion and exclusion criteria.Results: The subjects consisted of 38 limbs from 19 people, 11 (57.9%) males and 8 (42.1%) women aged 47-68 years. Spearman test showed a positive correlation was signifcant between ABI with APSV (r = 0.549, p <0.001). Correlation between ABI and pulse oximetry; pulse oximetry and APSV showed weak signifcant negative correlation (r = -0.347, p <0.05 and r = -0.369, p <0.05). Only APSV which has a strong positive correlation with clinical PAD signifcantly (r = 0.743, p <0.001).Conclusions: There is no strong correlation between ABI, pulse oximetry and APSV in DM patients without abdominal obesity. APSV can replace ABI and pulse oximetry as a non-invasive examination of diabetic patients for screening and follow-up PAD
