Handgrip exercise increases postocclusion hyperaemic brachial artery dilatation

OBJECTIVE: To examine the effect of handgrip exercise induced ischaemia on non-invasive assessment of endothelial function in the brachial artery. DESIGN AND SETTING: High frequency ultrasound was used to measure brachial artery diameter at rest and after reactive hyperaemia induced by forearm cuff occlusion with and without handgrip exercise induced ischaemia. SUBJECTS: 10 healthy subjects, < 40 years, without known cardiovascular risk factors. MAIN OUTCOME MEASURES: Brachial artery dilatation and blood flow. RESULTS: Hyperaemia following forearm occlusion with handgrip exercise induced ischaemia increased brachial artery diameter significantly more than hyperaemia following occlusion alone, 6.9 (3.2)% and 4.5 (1.6)%, respectively (95% confidence interval 0.3% to 4.5%). There was no difference in peak blood flow with and without exercise induced ischaemia CONCLUSIONS: Handgrip exercise induced ischaemia with forearm occlusion caused more pronounced brachial artery dilatation than occlusion alone without change in peak blood flow. This suggests continued brachial artery responsiveness to the stimulus of ischaemia despite maximum blood flow and peripheral vasodilatation with occlusion alone.     

Antiplasmin correlates to arterial reactivity in a healthy population of 35-year-old men and women

OBJECTIVE: To study whether haemostasis function variables correlate with endothelial function and other vasomotion characteristics of the brachial artery in a randomly selected healthy population of 35-year-old men and women. DESIGN: Endothelial function was measured as flow mediated dilatation (FMD) of the brachial artery during reactive hyperaemia and the nonendothelial dependent dilatation after sublingual nitroglycerin (NTG) was administered. Haemostasis and fibrinolysis function were estimated by analysis of von Willebrand factor, plasminogen activator inhibitor-1, antiplasmin and fibrinogen. SETTING: A general medicine research centre and a university hospital. SUBJECTS: Randomly chosen men (n = 53) and women (n = 56). RESULTS: Univariate correlation analysis showed significant correlations between haemostasis factors, conventional risk factors for cardiovascular disease and indices of vasomotion of the brachial artery. In multivariate analysis, with haemostasis variables and conventional risk factors included, antiplasmin was the strongest explanatory variable for FMD. When antiplasmin was removed from the analysis, the r-value dropped from 0.46 to 0.35. Antiplasmin also correlated with NTG-induced dilatation (positively) and brachial diameter at rest (negatively), albeit less consistently. CONCLUSIONS: Antiplasmin correlates significantly and independently to FMD, reflecting endothelial function, and also to brachial artery diameter at rest and nitroglycerin-induced dilatation. In multivariate analysis these correlations of antiplasmin to arterial characteristics were stronger than for 'conventional' risk factors, such as smoking, blood pressure and serum cholesterol.     

Non-invasive measurement of endothelial function: effect on brachial artery dilatation of graded endothelial dependent and independent stimuli.

OBJECTIVE: To examine the relation between endothelial dependent and endothelial independent stimuli of varying intensity and measures of vascular function in the brachial artery of young healthy adults, to determine whether these responses are consistent and can be used to assess endothelial function. DESIGN AND SETTING: High resolution ultrasound was used to measure brachial artery diameter at rest, after reactive hyperaemia induced by forearm cuff occlusion, and after sublingual isosorbide dinitrate (ISDN). Each subject was assigned to a random order of six cuff occlusion times (30 seconds, 1.5, 2.5, 3.5, 4.5, and 8 minutes) and six doses of ISDN (10, 20, 50, 100, 200, and 400 micrograms). SUBJECTS: Three males and three females mean age 31 years (range 25 to 43) with no known risk factors for cardiovascular disease. MAIN OUTCOME MEASURES: Flow mediated, endothelial dependent dilatation was compared to duration of cuff occlusion, peak reactive hyperaemia, and duration of increased flow. Nitrate induced, endothelial independent dilatation was compared to dose of ISDN and change in flow. RESULTS: Vessel dilatation and duration of peak flow change increased with longer duration of cuff occlusion. After 4.5 minutes of occlusion, flow mediated dilatation was mean (SD) 96 (6)% of maximal response and did not increase significantly with longer occlusion times. No significant dilatation occurred after 10 or 20 micrograms of ISDN in any subject. With increasing doses up to 200 micrograms there was an increase in dilatation. Endothelial independent dilatation did not increase significantly with doses of ISDN above 200 micrograms. CONCLUSIONS: Measures of arterial function vary with duration of blood flow occlusion and ISDN dose. Maximum arterial response was reached in all subjects after 4.5 minutes of blood flow occlusion or 200 micrograms of ISDN. Therefore, these variables produce consistent reproducible measures of endothelial function.     

高频超声检测高血压患者血管内皮舒张功能的探讨

Blood flow through the brachial artery at different temperatures in patients with Raynaud's phenomenon

Blood flow through the brachial and radial artery at different temperatures and during reactive hyperaemia was measured in 23 patients with Raynaud's phenomenon (9 patients with Raynaud's disease, 7 - Raynaud's syndrome with thoracic outlet syndrome (TOS), and 8 - Raynaud's syndrome and scleroderma), and 11 control subjects. Blood flow was determined by an ALVAR pulse-wave Doppler system enabling measurement of vessel diameter and blood flow rate. The measurements suggest that the blood flow through brachial artery reflects the changes of blood flow through the hand immersed in water of different temperatures. Maximum vasoconstriction was the same in all groups of Raynaud's phenomenon. The lowest blood flow at higher temperatures and during reactive hyperaemia was found in patients with scleroderma, whereas in the group of TOS and partly in patients with Raynaud's disease one can suspect only functional changes.     

Blood lipids and endothelial function in glycogen storage disease type III

We have assessed early indicators of arterial disease in patients with glycogen storage disease type III (GSD III; McKusick 232400), investigating the plasma lipid and lipoprotein profile and endothelial function. Eleven patients, aged 10–39 years, were recruited together with age-, sex- and smoking status-matched controls. Brachial artery responses were assessed by high-resolution ultrasonographic measurement of the diameter of the brachial artery at baseline, after reactive hyperaemia and in response to sublingual glyceryl trinitrate (GTN).The means of plasma cholesterol (total and HDL and LDL subfractions), triglycerides, apo-A1, apo-B, Lp(a) and the atherogenic index were similar in both groups. Cardiac troponin I was below the lower limits of detection (<0.03g/L) in all subjects. The GSD III patients had similar body mass index (BMI) and brachial artery diameter to the control group (BMI 22.6±5.6 vs 22.3±5kg/m²; brachial artery diameter 3.4±0.5 vs 3±0.7mm). When compared to the baseline diameter, the maximal flow-mediated dilatation of the brachial artery after reactive hyperaemia was 9.3±2.1% (mean±SD) in the GSD III patients and 6.5±3.5% in the control group, a difference of 1.8% (95% CI 0.07% to 5.5%). The maximal dilatation of the brachial artery after GTN administration was 18.3±6.4% in the GSD III patients and 17.9±6.5% in the control group, a difference of 0.4% (95% CI –6.9% to 7.7%.In conclusion, we found no evidence of abnormal plasma lipid and lipoprotein profile or endothelial dysfunction in patients with GSD III. They are unlikely to be at increased risk of premature atherosclerosis.     

Reduction of peripheral flow reserve impairs endothelial function in conduit arteries of patients with essential hypertension

BACKGROUND: A diminished flow reserve in resistance vessels is a hallmark of hypertensive microvascular disease. Hypertension is associated with structural alterations in the microcirculation and a reduced endothelium-dependent dilation in conduit arteries. Both have been demonstrated to predict future cardiovascular events. OBJECTIVE: We hypothesized that a reduced peripheral flow reserve impairs endothelial function in upstream conduit arteries in patients with arterial hypertension. DESIGN: In 43 hypertensive patients (HT) and 38 normotensive controls (NT) endothelial function of the brachial artery was assessed by measurement of flow-mediated dilatation (FMD), using high-resolution ultrasound. Peripheral flow reserve (FR) was determined via measurements of forearm blood flow at rest and during increments of reactive hyperaemia, using venous occlusion plethysmography. RESULTS: FMD was markedly impaired in HT (3.6 +/- 0.3%) as compared with NT (10.2 +/- 0.3%), whereas maximum brachial artery diameter following endothelium-independent dilatation was similar in both groups. In hypertensive patients FR was significantly reduced (HT, 3.2 versus NT, 6.0) during reactive hyperaemia after 5 min of ischaemia. FR was associated with FMD (r = 0.68, P < 0.01). Multiple stepwise regression analysis identified FR as a strong independent variable determining the extent of FMD (r2 = 0.46, P < 0.01). In HT the dose-response curve of FMD upon stepwise increases of FR was shifted significantly to the right. Normalization of FR improved FMD in HT by more than 60%. CONCLUSIONS: In essential hypertension a reduced FR contributes to the endothelial dysfunction of upstream conduit arteries. These findings may have therapeutic and prognostic implications in patients with arterial hypertension.     

Does a glass of red wine improve endothelial function?

AIMS: To examine the acute effect of red wine and de-alcoholized red wine on endothelial function. METHODS AND RESULTS: High frequency ultrasound was used to measure blood flow and percentage brachial artery dilatation after reactive hyperaemia induced by forearm cuff occlusion in 12 healthy subjects, less than 40 years of age, without known cardiovascular risk factors. The subjects drank 250 ml of red wine with or without alcohol over 10 min according to a randomized procedure. Brachial artery dilatation was measured again 30 and 60 min after the subjects had finished drinking. The subjects were studied a second time within a week of the first study in a cross-over design. After the red wine with alcohol the resting brachial artery diameter, resting blood flow, heart rate and plasma-ethanol increased significantly. After the de-alcoholized red wine these parameters were unchanged. Flow-mediated dilatation of the brachial artery was significantly higher (P<0.05) after drinking de-alcoholized red wine (5.6+/-3.2%) than after drinking red wine with alcohol (3.6+/-2.2%) and before drinking (3.9+/-2.5%). CONCLUSION: After ingestion of red wine with alcohol the brachial artery dilated and the blood flow increased. These changes were not observed following the de-alcoholized red wine and were thus attributable to ethanol. These haemodynamic changes may have concealed an effect on flow-mediated brachial artery dilatation which did not increase after drinking red wine with alcohol. Flow-mediated dilatation of the brachial artery increased significantly after de-alcoholized red wine and this finding may support the hypothesis that antioxidant qualities of red wine, rather than ethanol in itself, may protect against cardiovascular disease.
