Abstract

Objectives: To find out the relationship between arterial stiffness by pulse wave velocity with some risk factors in patients with chronic ischemic heart disease (CIHD). Subjects and methods: The patient group included 61 patients with chronic ischemic heart disease (defined as angiographic percent diameter stenosis ≥ 50%). The control group included 31 patients had normal coronary angiography. Results: The average age of the control group and the CIHD group was 68,26 ± 6,66 and 70,10 ± 7,15 years, respectively. The male in CIHD group was 60,7%, higher than the female group (39.3%). The mean PWV of CIHD group (15.66 ± 1.88 m/s) was higher than control group (13.35 ± 1.99 m/s). The incidence of elevated PWV (≥ 14 m/s) in the patient group (85.2%) was significantly higher than control group (38.7%). Increased PWV was associated with CIHD with OR = 9,148 (95% CI: 3,327 – 25,153). PWV in hypertensive patients of  CIHD and control groups were: 15.75 ± 1.99 and 13.8 ± 1.83 m/s, respectively; in patients with diabetes mellitus (DM): 15.89 ± 2.07 and 14.06 ± 1.29 m/s; smokers: 15.76 ± 1.97 and 13.82 ± 1.45 m/s; overweight people: 15.69 ± 1.79 and 13.59 ± 2.12 m/s. Conclusion: The mean PWV of CIHD group was higher than control group. The incidence of elevated PWV (≥ 14 m/s) in CIHD was more than control group. In patients with hypertension, diabetes, smoking, overweight, the PWV of the CIHD group was significantly higher than that of the control group, p < 0.05.
