Abstract

Objective :

It is well known that obesity is a controllable cardiovascular risk factor and has effects on other risk factors, including high blood pressure (HTA). It is also known to be more difficult to control hypertension in these patients with obesity (POB), requiring more treatment settings to maintain blood pressures (BP) below 140/90. In according to these data, we performed an assessment of the central pressures in obese patients with controlled BP in the office.

Objectives:

The aim of this study is to evalue central systolic and diastolic blood pressures (CSBP,CDBP) in obese patients whose peripheral blood pressure was apparently controlled at office.

Design and method:

We studied, 68 POB (67 ± 7 average years old,45 women and 23 men, BMI > 30) and compared to 150 hypertensive patients (66 ± 9 average years old, 90 women and 60 men, BMI < = 25), non obese (P no OB), who received treatment to maintain BP below 140/90 mmHg in office. All of them submitted to a study to measure CSBP,CDBP, augmentation index (AI) and pulse wave velocity (PWV) in a observational and prospective study

Results:

Results of these groups were compared and shown in the following table:

Conclusions:

According to our data, obesity significantly increases systolic and diastolic central pressures and also, arterial stiffness, setting these patients in a high risk group, despite apparently having good peripheral blood pressure control. We have to take into account these data to increase our control on these kind of patients.
