Abstract:

Background: Cardiovascular disease remains the leading cause of death worldwide. Uncontrolled hypertension places patients atsignificant risk ofcomplications including coronary artery disease, cerebrovascular disease and cardiovascular death. Arterial stiffness is recognized as an important determinant of outcome in hypertensive population. Arterial stiffness can be measured from stiffness indices by digital volume pulse (DVP) wave recording.

Aim and Objective: To compare the arterial stiffness indices (stiffness index [SI] and reflection index [RI]) of DVP between normal and hypertensive patients.

Materials and Methods: A study was conducted in 50 normal subjects (control group)and 50 hypertensive patients (study group)within the age group of 40‑60 years. After a detailed history, baseline parameters were measured. DVP was recorded and Arterial stiffness Indices were measured from DVP in both the groups. Results: There was significant (P < 0.001)increase in both SI and RI in hypertensive patients when compared to normotensive subjects. The results were statistically analyzed by using SPSS Software version 17.0.

Conclusion: By using noninvasive and cost effective method of arterial stiffness indices by finger photo pulse plethysmography, we can predict the vascular complications of hypertensive patients.
