Objective: To assess the impact of concomitant use of aspirin, BB (metoprolol), statin (atorvastatin), and metformin on central haemodynamics and arterial stiffness parameters in treated hypertensive patients. Materials and Methods: We did a cross-sectional study on 476 treated hypertensives. Oscillometric PWA was accomplished by Mobil-o-Graph (IEM, Germany) and groups were stratified using low-dose aspirin, statin, BB, or metformin. Parameters studied were brachial hemodynamics (BP, heart rate, and rate pressure product), arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, and pulse pressure amplification), and central hemodynamics (central BP, cardiac output, and stroke work). Results: All pairs were matched by or comparable for major confounding factors except concomitant use of drugs. The use of BB, aspirin, and statin had favorable effect on brachial and central hemodynamics. Metformin use had effect more on central than brachial hemodynamics. BB and metformin had negative, statin had indifferent, and aspirin had positive effect on arterial stiffness. Only few of these differences had statistical significance. Frequency of central pulse pressure ≥40 was insignificantly affected by drugs studied. Conclusions: Concomitant aspirin, BB, and metformin in hypertensives have favorable effects on hemodynamics, brachial more than central. Arterial stiffness has positive impact of metformin and negative impact of BB use. These effects must be considered in studies focusing hypertensive therapies. It remains inconclusive whether these results are due to drugs or their indication.

Objective: To study the effect of different classes and combinations of antihypertensive agents on arterial stiffness and central hemodynamic parameters. Materials and Methods: A cross-sectional study was conducted in 446 treated apparently healthy hypertensives. Oscillometric PWA was performed by Mobil-o-Graph (IEM, Germany) to derive cardiovascular parameters that were further analyzed in groups stratified by antihypertensive used. Study parameters were brachial hemodynamics (blood pressure (BP), heart rate, and rate pressure product); arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, and pulse pressure amplification); and central hemodynamics (central BP, cardiac output, and stroke work). Statistical significance was kept at P

Introduction: Diabetes mellitus (DM) is a significant risk factor for nephropathy and cardiovascular morbidity. Pulse wave analysis (PWA) gives direct inference of brachial hemodynamics (BH) and central hemodynamics (CH). We studied relation of them with diabetic nephropathy (DN) among type-2 diabetics (T2D). Methods: We studied oscillometric PWA by a cross-sectional study in 160 T2Ds. Using Mobil-o-Graph (IEM, Germany), we derived BH (blood pressure, pulse pressure index, rate pressure product) and CH (aortic pressure, cardiac index, stroke volume index, stroke work). They were further compared and associated with DN in terms of creatinine, proteinuria, and estimated glomerular filtration rate (eGFR). Results: There were 89 males, mean age 56 years, mean duration 4.8 years, 80% hypertensive predominantly using ACE inhibitors, poor glycemic blood pressure (BP) control, mainly mild-to-moderate DN, mean eGFR 88.2, 34% prevalence of proteinuria. Arterial stiffness was high with female disadvantage. BH and CH parameters were not different with or without DN using proteinuria or eGFR (60 cutoff) criteria. BH, CH correlated insignificantly with creatinine and eGFR. Female disadvantage, correlation with bSBP and aSBP were only significant results. Conclusions: BH and CH are not related to eGFR and proteinuria in predominantly hypertensive, Gujarati diabetics with mild-to-moderate nephropathy suggesting need of other cardiovascular parameters.

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

Introduction: Diabetes mellitus (DM) imposes significant cardiovascular risk beyond raised blood pressure. Pulse wave analysis (PWA) infers directly about the same by arterial stiffness (AS) assessment. We studied the relation between AS and diabetic nephropathy (DN) in type 2 diabetics (T2D). Materials and Methods: We evaluated 164 T2Ds in a cross-sectional study. Oscillometric PWA performed by Mobil-o-Graph (IEM, Germany) reported AS parameters such as augmentation pressure (AP), augmentation index at heart rate 72, reflection magnitude, and aortic pulse wave velocity (aPWV). DN was evaluated by creatinine, proteinuria, and estimated glomerular filtration rate (eGFR). Parameters were further analyzed for the effect of gender, proteinuria, and grades of DN by eGFR. Multiple linear regressions were used to find significant predictors. P
