Background: Increased vascular stiffness and excessive blood pressure (BP) pulsatility are important risk factors for age-related morbidity. Vascular stiffness and BP pulsatility are related, with a prevailing view that hypertension antedates and contributes to premature vascular aging and a secondary increase in vascular stiffness. However, temporal relations between comprehensive vascular measures and BP elevation have not been fully delineated in a large community-based sample. Methods: We examined longitudinal relations of BP and 3 measures of vascular stiffness and pressure pulsatility derived from arterial tonometry (carotid-femoral pulse wave velocity [CFPWV], forward wave amplitude and augmentation index) over a 7-year period in 1,898 Framingham Offspring participants (mean age 60 yrs, 1,057 women). We also examined relations between measures of microvascular and endothelial function derived from brachial artery Doppler and future progression of BP or vascular stiffness. Results: In multivariable-adjusted regression models, baseline tonometry measures were separately and jointly associated with higher systolic and pulse pressure and incident hypertension ( Table ). Conversely, higher baseline BP was associated with higher forward wave amplitude and augmentation index (all p<0.05) but not CFPWV at follow-up. Higher baseline resting brachial artery flow and lower flow-mediated dilation were associated with incident hypertension in models that included BP and tonometry measures ( Table ). Conclusion: Higher aortic stiffness (CFPWV), pressure pulsatility (forward wave amplitude), and wave reflection (augmentation index) and lower flow-mediated dilation are associated with blood pressure progression and incident hypertension. Our findings support the notion of aortic stiffness as a precursor of hypertension and further suggest a vicious cycle of increasing pressure pulsatility with advancing age. Table.

Objective. To assess relation between central blood pressure and arterial stiffness with cardiovascular risk factors. Design and methods. 116 subjects considering themselves healthy were examined. 63 showed blood pressure elevation. Anthropometry was performed and fasting blood specimens were obtained from all patients. Plasma glucose and lipids levels were measured. Pulse wave velocity (PWV) and augmentation index (AI) were measured by Sphygmocor Px device (Australia). Results. Parameters of arterial stiffness were strongly associated with hypertension, increased waist circumference, age, cholesterol level, and metaboloc syndrome. Females had higher AI as compared to males. Conclusion. Central blood pressure and arterial stiffness are determined not only by age and peripheral blood pressure but by cholesterol level and anthropometric parameters as well.

CONTEXT AND OBJECTIVES: Assessment of central blood pressure (BP) has grown substantially over recent years because evidence has shown that central BP is more relevant to cardiovascular outcomes than peripheral BP. Thus, different classes of antihypertensive drugs have different effects on central BP despite similar reductions in brachial BP. The aim of this study was to investigate the effect of nebivolol, a β-blocker with vasodilator properties, on the biochemical and hemodynamic parameters of hypertensive patients.DESIGN AND SETTING: Experimental single cohort study conducted in the outpatient clinic of a university hospital.METHODS: Twenty-six patients were recruited. All of them underwent biochemical and hemodynamic evaluation (BP, heart rate (HR), central BP and augmentation index) before and after 3 months of using nebivolol.RESULTS: 88.5% of the patients were male; their mean age was 49.7 ± 9.3 years and most of them were overweight (29.6 ± 3.1 kg/m2) with large abdominal waist (102.1 ± 7.2 cm). There were significant decreases in peripheral systolic BP (P = 0.0020), diastolic BP (P = 0.0049), HR (P < 0.0001) and central BP (129.9 ± 12.3 versus 122.3 ± 10.3 mmHg; P = 0.0083) after treatment, in comparison with the baseline values. There was no statistical difference in the augmentation index or in the biochemical parameters, from before to after the treatment.CONCLUSIONS: Nebivolol use seems to be associated with significant reduction of central BP in stage I hypertensive patients, in addition to reductions in brachial systolic and diastolic BP.

Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice, yet there is a lack of information about the hemodynamic profile and arterial stiffness of these patients. Purpose: The purpose of this study is to describe the differences in arterial stiffness and central blood pressures in patients with paroxysmal/persistent AF compared to a healthy control group. Methods: We included 76 patients with paroxysmal and persistent AF who underwent electrical cardioversion or pulmonary vein isolation (PVI) for AF. Carotid-femoral pulse wave velocity (cfPWV), augmentation index (AIx) and central blood pressure (cBP) were measured by applanation tonometry. All measurements were done in sinus rhythm (SR). We compared the results with 75 healthy age matched individuals. Results: Patients with a history of AF had higher cfPWV compared to the control group (8,0 m/s vs 7,2 m/s, p<0,001). AF patients also had higher central systolic blood pressure (cSBP) (118 mmHg vs 114 mmHg, p=0,03) and central pulse pressure (cPP) (39 mmHg vs 37 mmHg, p=0,03), without differences in peripheral systolic pressure (pSBP) (127 mmHg vs 123 mmHg, p=0,13), peripheral diastolic blood pressure (pDPB) (78 mmHg vs 76 mmHg, p=0,14) and peripheral pulse pressure (pPP) (48 mmHg vs 47 mmHg, p=0,37). There was no difference in heart rate (HR) (58 vs 61 bpm, p=0,08) (Table 1). In a multiple regression analysis (adjusted R 2 = 0,37) where cfPWV was set as the dependent variable and adjusting for age, sex, HR, weight, mean central arterial pressure (cMAP), estimated glomerular filtration rate (eGFR), the AF group remained to be an independent predictor for cfPWV (p=0,016). Conclusions: Patients with atrial fibrillation have a higher cSBP, cPP and cfPWV compared to healthy subjects without differences in peripheral blood pressure and HR. These findings support the hypothesis that arterial stiffness may play an important role in the development of atrial fibrillation.
