Factores que influyen en la diferencia de medida de presión arterial entre el método auscultatorio y el oscilométrico
Fundamento y objetivo El metodo auscultatorio mediante esfigmomanometro de mercurio esta siendo sustituido por otros metodos de medida de presion arterial, de los que el mas utilizado es el oscilometrico. Se analiza las posibles discrepancias de medida entre ambos metodos y los factores que influyen en ellas. Material y metodo Se obtuvieron medidas de presion arterial (PA) mediante esfigmomanometro de mercurio, con un monitor Spacelabs, en el mismo brazo y mediante un metodo secuencial. La relacion entre ambas medidas se analizo mediante los coeficientes de correlacion de Pearson y el metodo de Bland y Altman. Se calcularon las diferencias entre ambos metodos de medida. Se analizo los facto…
Effects of nebivolol and atenolol on central aortic pressure in hypertensive patients: a multicenter, randomized, double-blind study.
The main objective was to compare the mean change in augmentation index of hypertensive patients treated with nebivolol or atenolol.Multicenter, double-blind randomized study conducted in six Spanish centers. We enrolled outpatients between the ages of 40 and 65 years with mild or moderate essential hypertension (systolic blood pressure, SBP ≥ 140 mmHg to ≤ 179 mmHg and diastolic blood pressure, DBP ≥ 90 mmHg to ≤ 109 mmHg after a 2-week run-in placebo period). Patients received nebivolol 5 mg or atenolol 50 mg once daily. At week 3, atenolol could be titrated up to 100 mg qd for non-responders. Additionally, patients not achieving normal blood pressure after 6 weeks could be treated with 2…
Pulse pressure amplification and its determinants
Background. Pulse pressure (PP) amplification expressed as the peripheral-to-central PP ratio has gained importance in the assessment of cardiovascular phenotypes and cardiovascular risk. The aim of the present study was to assess the relationship between PP amplification, large vessel parameters and peripheral blood pressure (BP) to gain insights into the amplification phenomenon. Methods. Peripheral BP, central BP and carotid-femoral pulse wave velocity (cfPWV) were assessed using the OMRON M6, SphygmoCor and Complior devices, respectively, in 741 adults attending the hypertension outpatient clinic. Analysis of covariance, partial correlations and multiple linear regression models were pe…
