Cerebral Blood Flow, Metabolism and Mean Arterial Pressure Changes Following Unilateral Internal Carotid Endarterectomy: Cerebral Ischemia and Elevated Systemic Arterial Pressure • Cerebral blood flow and metabolism studies were performed on 13 patients before and after unilateral carotid endarterectomy for severe atheromatous occlusive disease. Mean brachial arterial pressure was monitored dur...

To investigate the role of the sympathetic control mechanism in the antihypertensive effect of dietary calcium supplementation, we examined whether a high calcium diet affected mean arterial pressure, renal sympathetic nerve activity, heart rate, and overall and central properties of the arterial baroreceptor reflex in salt-loaded young spontaneously hypertensive rats (SHR). Six-week-old SHR we...

The role of nucleus tractus solitarius (NTS) in cardiovascular system regulation is controversial. On the other hand, the problem of hypertension in diabetic animals is the subject of many research programs. The aim of present study was to determine whether inactivation of NTS could affect blood pressure and heart rate in diabetic rats. To this end, stereptozotocin induced diabetic rats were an...

Detailed echocardiographic evaluation was performed on sixty-four normal persons without any cardiovascular risk factor and clinic blood pressure of 120/80 mm of Hg or less with an aim to find, if there are subclinical echocardiographic changes even in this population. There was significant positive linear correlation between mean arterial pressure and LV mass index. On dividing the patients ac...

Intra-aneurysmal pressure was studied in an experimental model of saccular aneurysm in dogs, using a vein pouch grafted onto a common carotid arterial bifurcation. The mean and the pulse pressures were recorded simultaneously from within the aneurysm and within the common carotid artery, before and after 50% proximal carotid artery stenosis. These experiments were performed under systemic normo...

The relative importance of systolic blood pressure (SBP) versus diastolic blood pressure (DBP) in predicting the risk of ischaemic heart disease (IHD) mortality is controversial. We have re-examined SBP compared to D BP and other combinations of SBP and D BP in predicting the risk of IHD mortality in a long-term cohort study oflO,541 men and women in the West of Scotland. During a mean fo...

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...

BACKGROUND Sampler filling time begins with the initial flash of blood in the needle hub until the preset sampler volume is obtained. Previous studies have shown statistically significant differences between arterial and venous sampler filling times, but included only a few subjects with abnormal blood pressures. OBJECTIVE To determine whether the time required to fill a vented arterial sampl...
