Peripheral Arterial Disease in Diabetes and its Relation to Cardiovascular Risk Factors in Women

Abstract

Objectives: Peripheral arterial disease (PAD) is characterized by occlusive disease in the abdominal aorta, iliac, and femoral arteries, leading to reduced blood flow and complications. Diabetes mellitus (DM) is known to contribute to the development and progression of PAD due to factors such as hyperglycemia, dyslipidemia, endothelial dysfunction, and inflammation. However, PAD may be underdiagnosed in women with DM, leading to adverse cardiovascular outcomes. The present study aimed to investigate the prevalence of PAD in women with type 2 DM (T2DM) and its relationship with cardiovascular risk factors. Materials and Methods: This hospital-based, cross-sectional, and observational study was conducted for a period of 3 months from June 10, 2023, to September 10, 2023, in the outpatient department of general medicine. After obtaining the approval from the Institutional Ethical Committee, the study was performed according to the Declarations of Helsinki and Good Clinical Practice requirements for human subject protection. Non-probability purposive sampling technique was used to enroll participants. Participants underwent face-to-face interviews and clinical examinations. Sociodemographic data, medical history, and pharmacotherapy details were collected. Laboratory investigations were conducted, including blood glucose, lipid profile, and glycosylated hemoglobin (HbA1C) tests. The ankle-brachial index (ABI) was measured. Results: The results showed that the majority of the participants were between 50 and 70 years of age, married, and had a high school education. Participants had an average body mass index (BMI) indicating overweight, and the average duration of diabetes was 6.571 years. Hypertension was the most prevalent comorbidity. Overweight, obesity I, and obesity II were present in 15.25% (n = 19), 33.6% (n = 42), and 8.8% (n = 11), respectively. Average values for HbA1C, fasting blood glucose (FBG), and postprandial blood glucose (PPBG) were within the diabetic range. ABI was normal in the right side, left side, and bilateral in 43.2%, 56%, and 14.4% of participants, respectively. ABI was borderline on the right side, left side, and bilateral in 40.8%, 36.8%, and 22.4% of participants, respectively. PAD was observed on the right side, left side, and bilateral in 16%, 7.2%, and 4% of participants, respectively. BMI, duration of DM, glycosylated hemoglobin, FBG, and PPBG showed significant negative correlations with ABI. Age, triglycerides, high-density lipoprotein, and low-density lipoprotein did not show any statistically significant correlation with ABI. Conclusion: The study highlighted the importance of screening for PAD in women with T2DM to improve cardiovascular outcomes. The findings shed light on the prevalence of risk factors for PAD and their association with the disease. These insights can contribute to the development of targeted interventions to reduce adverse clinical outcomes in this population.
