BACKGROUND: Arterial hypertension affects endothelial function and arterial stiffness. The angiotensin (AT1) receptor antagonist irbesartan improves endothelial function and arterial stiffness in hypertensive patients. Nebivolol, a beta(1)-selective beta blocker, reduces systemic vascular resistance and stimulates nitric oxide release thus exerting positive effects on vascular function. However, comparative studies on the ...

AIM: Considerable asynchrony during pressure-support ventilation has been reported. While the beginning of active inspiration is usually identifiable in the airway pressure (Paw) curve (the inspiratory trigger), there is still a need for accurate, non-invasive methods to identify the end of inspiration. To test the hypothesis that inspiration, particularly the ...

Intrinsic positive end-expiratory pressure (auto-PEEP) is a common occurrence in patients with acute respiratory failure requiring mechanical ventilation. Auto-PEEP can cause severe respiratory and hemodynamic compromise. The presence of auto-PEEP should be suspected when airflow at end-exhalation is not zero. In patients receiving controlled mechanical ventilation, auto-PEEP can be estimated ...

BACKGROUND: Acute hemorrhage is the principal cause of death in trauma patients, with most fatalities occurring during the pre-hospital phase. Recently, intra-abdominal insufflation by carbon dioxide has been shown to drastically reduce bleeding in vascular and splanchnic hemorrhagic animal models simulating the pre-hospital phase. Here, we propose that using dialysate ...

Using the Sphygmocor device it is recommended that the radial pressure wave is calibrated for brachial systolic blood pressure (SBP) and diastolic blood pressure (DBP). However it has been suggested that brachial-to-radial pressure amplification causes underestimation of central blood pressures (BPs) using this calibration. In the present study we examined ...

Abstract Objectives. Sympathetic activation has a role in the development of left ventricular hypertrophy (LVH). The presynaptic α(2C)-adrenoceptor inhibits the release of norepinephrine from sympathetic nerve terminals in the heart. A deletion polymorphism in the α(2C)-adrenoceptor (α(2C)Del322-325) generates a hypofunctional α(2C)-adrenoceptor, which may result in chronic adrenergic signalling. This study ...
