Influence of age, body mass index, and blood pressure on the carotid intima-media thickness in normotensive and hypertensive patients

We investigated whether body mass index and blood pressure have an additive influence on the carotid intima-media thickness (IMT)...

Estimation of spontaneous baroreflex sensitivity using transfer function analysis: effects of positive pressure ventilation

To determine the short-term effects of non-invasive positive pressure ventilation (PPV) on spontaneous baroreflex sensitivity, we acquired time series of RR interval and beat-to-beat blood pressure in 55 healthy volunteers (mean age 46.5±10.5 years), who performed breathing tests on four occasions at frequencies of 12 and 15/min, with application of PPV of 5 mbar, and without positive pressure (control)...
