Introduction: Diabetes is a modern epidemic imposing significant cardiovascular risk. Immediate and discrete parameters such as arterial stiffness and central hemodynamics are studied scarcely. Pulse wave analysis (PWA) offers noninvasive measurement of the same and we performed that in diabetics. Materials and Methods: We performed a case–control study on 148 treated diabetic not on antihypertensive and 148 nondiabetic normotensive controls. Oscillometric PWA was performed by Mobil-O-Graph (IEM). Parameters were further analyzed for effect of gender, physical activity, body mass index (BMI; cut-off 23), glycemic control, and disease duration (cut-off 4 years). Multiple linear regressions were used to find significant predictors. P <0.05 was taken as statistical significance. Results: Cases had significantly raised brachial hemodynamics (blood pressure, heart rate, rate pressure product), arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, pulse pressure amplification), and central hemodynamics (central blood pressure, cardiac output, stroke work) than controls. In the case group, female gender, BMI ≥ 23, and physical inactivity were the significant factors affecting results (arterial stiffness more than central hemodynamics); glycemic control and duration were not. Heart rate was the major predictor of study parameters. Brachial pressure parameters were not significant predictors of corresponding central pressure parameters. Conclusion: Gujarati diabetics not using any antihypertensive had adverse profile of beyond brachial blood pressure discrete cardiovascular parameters, independent of duration and glycemic control, related to gender, BMI, and physical activity, indicating vascular progeria in the absence of hypertension. This baseline study suggests further work on these potential parameters.
