background: systolic blood pressure (sbp) and diastolic blood pressure (dbp) are a multi-factorial traits and significantly heritable.glutathione s-transferase (gst) enzyme is involved in detoxification of reactive oxygen species. the present study aimed at finding out the association between gstm1 and gstt1 polymorphisms and mean arterial pressure (map) in iranian population. map, as the impor...

Low arterial pressure* (Hypopiesis) is a term applied to low arterial pressure in general, whether physiological or pathological, temporary or permanent, congenital or acquired. Hypopiesia (primary low arterial pressure) is a clinical series of primary congenital, constitutional or familial origin, characterised by persistently lowered arterial pressure occurring as a part of a low vitality sta...

Objectives To test the usefulness of continuous assessment of arterial load based on a 3-element Windkessel model by a combined analysis of the esophageal Doppler derived-blood flow and arterial pressure waveform, against standard frequency-domain analysis of arterial impedance. Methods Time-domain variables of arterial impedance were obtained by the simultaneous analysis of the Doppler derived...

Three anephric patients were studied during sequential periods of normal hydration and overhydration. The increase in arterial pressure caused by the overhydration (+ 7% of body weight) was associated with an increase in peripheral resistance (+ 21.1%, P < 0.01). The elevation of peripheral resistance was preceded by an increased cardiac output (+ 22.3%, P < 0.02) which then fell part way to co...

Arterial baroreceptor reflex control of renal sympathetic nerve activity (RSNA) has been proposed to play a role in long-term control of arterial pressure. The hypothesis that the "set point" of the acute RSNA baroreflex curve determines the long-term level of arterial pressure is presented and challenged. Contrary to the hypothesis, studies on the long-term effects of sinoaortic denervation (S...

BACKGROUND Continuous noninvasive arterial pressure monitoring devices are available for bedside use, but the accuracy and precision of these devices have not been evaluated in a systematic review and meta-analysis. METHODS The authors performed a systematic review and meta-analysis of studies comparing continuous noninvasive arterial pressure monitoring with invasive arterial pressure monito...

To the Editor:—We read with great interest the article by Petersen et al., which demonstrated the expected clinical response to the three anesthetic agents studied. An increase in arterial pressure may result in an increase in the cerebral perfusion pressure and reduce reflex cerebral vasodilatation, potentially resulting in reduced intracranial pressure. We note that the mean arterial pressure...

Background:  Patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (BCIS) which is a leading cause of intraoperative complications. The purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   Methods:  Cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. A...
