Objective:To determine the relations between endothelium-dependent vasodilator function and blood flow in the brachial and coronary arteries in patients with suspected coronary artery disease.Methods:Twenty-eight patients with suspected coronary artery disease underwent brachial artery endothelial function test by using high-resolution B-mode ultrasound before coronary angiography(CAG)and coronary flow reserve(CFR)test by using intracoronary Doppler technique.The correlation of coronary artery dilatation induced by an increase in blood flow after intracoronary adenosine infusion and brachial artery flow-mediated dilatation(FMD) following reactive hyperemia was evaluated.The relation between the change of brachial artery blood flow and CFR was also studied.Results:There was a positive correlation between brachial FMD and percent change of coronary diameter after adenosine infusion(12.50%±9.35% vs 11.38%±7.55%,r=0.425,P=0.02).There was also a weak negative relation between brachial flow change following reactive hy-peremia and CFR(r=-0.397,P=0.04).Conclusion:There is a correlation between the coronary endo-thelial function and the CFR by ultrasonic determination of brachial flow changes following reactive hyperemia. 展开更多

Objectives To understand the effect of carvedilol on the coronary vascular endothelial function of the patients with coronary heart disease after percutaneous transluminal coronary angioplasty (PTCA). Methods 51cases, having one or more than two branches narrow ( ≥ 70% ) , were diagnosed by coronary angiography. These patients were divided randomly into carvedilol group (n = 28) and control group ( n = 23) who did not take carvedilol. Endothelin (ET) and nitro dioxide (NO) levels of peripheral blood were measured before and after PTCA, before and after two weeks by taking earvedilol. Results Compared with the ET and NO levels before PTCA, ET were markedly increased and NO were decreased after PTCA (p <0. 05) ; compared with the ET and NO levels before taking carvedilol, ET were decreased and NO were increased after two week (p <0.05 ) , but the ET and NO levels of the control group did not change in the period of two weeks observation (p > 0.05). Conclusions Carvedilol may improve the coronary vascular endothelial function after PTCA. 展开更多

Aim: To investigate the relationship between androgen level and the indexes indicating endothelial function in male patients with coronary heart disease (CHD). Methods: We registered the following data for 106 50-70-year-old men: age, weight, blood lipid, including total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride, whether a smoker, sugar levels, blood pressure, free testosterone (FT), vascular cell adhesion molecule- 1 (VCAM- 1) and the intima-media thickness (IMT) of common carotid artery, common carotid diameter, maximum velocity in systolic phase, minimum velocity in diastolic phase and resistent index. Among the 106 men, 51 were patients with CHD. The relationships between FT level, VCAM-1 concentration and IMT were examined, respectively, using a stepwise linear regression technique among all the 106 men. Results: There was no statistical difference in terms of age, blood pressure, whether a smoker, sugar levels, HDL-C, minimum velocity in diastolic phase, resistent index between male CHD patients and controls; whereas results for weight, total cholesterol, low density lipoprotein cholesterol, triglyceride, VCAM- 1 and IMT of male CHD patients were higher than those of controls; FT level and maximum velocity in systolic phase were lower. It was found that among all the objects, FT level was inversely correlated with IMT and VCAM-1 concentration. Condusion: FT level was inversely correlated with VCAM-I concentration and IMT which are indicators of endothelial function. (Asian JAndro12008 Mar; 10: 214-218) 展开更多

AIM: To investigate the effects of different doses of aspirin on coronary endothelial function. METHODS: The study included 139 Japanese subjects(mean age, 60 years; 53 women) with angiographically normal coronary arteries. Patients were distributed into GroupⅠ(n = 63), who was administered aspirin and Group Ⅱ(n = 76), the control, who were not administered aspirin. GroupⅠwas further divided into GroupⅠa(n = 50, low-dose aspirin, 100 mg) and GroupⅠb(n = 13, high-dose aspirin, 500 mg). After a routine coronary angiography, acetylcholine(ACh; 3 and 30 μg/min successively) and nitroglycerin(NTG) were infused into the left coronary ostium over 2 min. The change in the diameter of the coronary artery in response to each drug was expressed as the percentage change from baseline values.RESULTS: The patient characteristics did not differ between the two groups. The change in coronary diameter in response to ACh was greater in GroupⅠthan in Group Ⅱ(P = 0.0043), although the NTG-induced coronary vasodilation was similar between groups. ACh-induced dilation was greater in GroupⅠa than in GroupⅠb(P = 0.0231). Multivariate regression analysis showed that a low-dose of aspirin(P = 0.0004) was one of the factors associated with ACh-induced dilation at 30 μg/min.CONCLUSION: In subjects with angiographically normal coronary arteries, aspirin only had a positive influence on coronary endothelial function at the low dose of 100 mg. This improvement of coronary endothelial function may be involved in the preventive effect of aspirin against future coronary events. 展开更多

AIM: To investigate endothelium-dependent and independent coronary microvascular functions in patients with vasospastic angina (VSA). METHODS: Thirty-six patients with VSA (30 men and 6 women; mean age, 58 years) were enrolled in this study. VSA was defined as ≥ 90% narrowing of the epicardial coronary arteries on angiography performed during a spasm provocation test, presence of chest pain, and/or ST-segment deviation on an electrocardiogram (ECG). Patients (n = 36) with negative spasm provocation test results and those matched for age and sex were enrolled as a control group (nonVSA group). Low-dose acetylcholine (ACh; 3 μg/min) was infused into the left coronary ostium for 2 min during the spasm provocation test. Following the spasm provocation test, nitroglycerin (0.2 mg) was administered intracoronally. Coronary blood flow (was calculated from quantitativeangiography and Doppler flow velocity measurements, and the coronary flow reserve was calculated as the ratio of coronary flow velocity after injection of adenosine triphosphate (20 μg) to the baseline value. Changes in the coronary artery diameter in response to ACh and nitroglycerin infusion were expressed as percentage changes from baseline measurements. RESULTS: Body mass index was significantly lower in the VSA group than in the nonVSA group. The fre- quency of conventional coronary risk factors and the rate of statin use were similar between the 2 groups. The left ventricular ejection fraction as evaluated by echocardiography was similar between the 2 groups. The duration of angina was 9 ± 2 mo. The results of blood chemistry analysis were similar between the 2 groups. Low-dose ACh did not cause coronary spasms. The change in coronary artery diameter in response to ACh was lower in the VSA group (-1.4% ± 9.3%) than in the nonVSA group (3.1% ± 6.5%, P 【 0.05), whereas nitroglycerin-induced coronary artery dilatation and coronary blood flow increase in response to ACh or coronary flow reserve did not differ significantly between the 2 groups. CONCLUSION: These findings suggest that microvascular coronary function may be preserved despite endothelial dysfunction of the epicardial coronary arteries in patients with VSA. 展开更多

Background Pulse wave velocity and flow-mediated vasodilation (FMD) are widely used as noninvasive modalities for evaluating atherosclerosis. However, it is not known whether pulse wave velocity is related to FMD in patients with coronary artery disease (CAD). Therefore, the present study was designed to investigate the alteration in brachial-ankle pulse wave velocity (baPWV) and endothelial function in CAD patients. Methods Thirty-three patients with CAD and thirty control subjects were recruited for this study, baPWV was measured non-invasively using a VP 1000 automated PWV/ABI analyzer (PWV/ABI, Colin Co. Ltd., Komaki, Japan). Endothelial function as reflected by FMD in the brachial artery was assessed with a high-resolution ultrasound device. Results baPWV was increased in CAD patients compared with control subjects [(1756.1±253.1) cm/s vs (1495.3±202.3) cm/s, P〈0.01]. FMD was significantly reduced in CAD patients compared with control subjects [(5.2±2.1) % vs (11.1±4.4) %, P〈0.01]. baPWV correlated with FMD (r =-0.68, P〈0.001). The endothelium-independent vasodilation induced by sublingual nitroglycerin in the brachial artery was similar in the CAD group compared with the control group.Conclusions CAD is associated with increased baPWV and endothelial dysfunction. Increased baPWV parallels diminished endothelial function. Our data therefore suggest that baPWV can be used as a noninvasive surrogate index in clinical evaluation of endothelial function. 展开更多

Objective: To study the effect of Shengmai injection (生脉注射液, SMI) on vascular endothelial and heart functions in coronary heart disease patients complicated with diabetes mellitus (CHD-DM). Methods: One hundred and twenty patients with CHD-DM, their diagnosis confirmed by coronary arteriography, were equally randomized into a control group treated with conventional treatment and a treated group treated with conventional treatment plus SMI. The changes in blood levels of nitric oxide (NO), endothelin-1 (ET-1) and angiotensin Ⅱ (Ang Ⅱ), as well as endothelium-dependent vascular dilating function and heart function in the patients were observed before treatment and after the 3-week treatment. Results: After being treated with SMI for 3 weeks, in the treated group, blood level of NO was raised significantly from 69.8±33.1 μmol/L to 120.1±50.8μmol/L, and ET-1 was lowered from 70.1±32.1 ng/L to 46.2±21.3 ng/L, respectively (P〈0.01); that of Ang Ⅱ was lowered from 81.3±24.3 ng/L to 50.2±27.3 ng/L (P〈0.01); brachial arterial post-congestion blood flow increasing rate was raised from 389.4±26.3% to 459.3±27.8% (P〈0.01); and the improvement in heart function as seen through the ejection fraction (EF) was increased from 44±5% to 68±6% (P〈0.01), all the changes being more significant than those in the control group (all P〈0.01). Conclusion: SMI can improve not only the endothelial function in CHD-DM patients, but also heart contraction significantly. 展开更多

Background:Ongoing low-grade inflammation and endothelial dysfunction persist in children with coronary lesions diagnosed with Kawasaki disease(KD).Statins,frequently used in the management of high cholesterol,have also shown to improve surrogate markers of infl ammation and endothelial dysfunction.This study was undertaken to investigate the effi cacy and safety of pravastatin in children with coronary artery aneurysms due to KD.Methods:The study enrolled 14 healthy children and 13 male children,aged 2-10 years,with medium-to-giant coronary aneurysms for at least 12 months after the onset of KD.Pravastatin was given orally to the KD group at a dose of 5 mg/day for children under 5 and 10 mg/day for children older than 5 years.To determine the effects of pravastatin on endothelial function,high-frequency ultrasound was performed before the start of the study and 6 months after pravastatin therapy.The parameters measured were brachial artery flow-mediated dilation(FMD),non-flow mediated dilation(NMD),and carotid artery stiffness index(SI).High sensitive C-reactive protein(hs-CRP)levels,the circulating endothelial progenitor cells(EPCs)number,and serum lipid profiles were also determined at baseline and after 6 months of pravastatin treatment.Results:Before treatment,the KD group had significantly decreased FMD(P<0.05)and increased SI and hs-CRP levels(P<0.05)compared with controls.After 6 months of pravastatin therapy,FMD improved significantly compared to the baseline KD group(3.16±6.49 to 10.05±7.74,P<0.05),but remained significantly less than that in the control group with no signifi cant changes in NMD and SI.There were signifi cant decreases in markers of inflammation after treatment.The hs-CRP levels decreased signifi cantly from 2.93±0.81 mmol/L to 2.14±0.82 mmol/L(P<0.05)and the serum apo-B and apo-B/apo-A1 ratio were also reduced(P<0.05)in the KD group.However,the circulating EPC number was not signifi cantly different between baseline and that following pravastatin treatment in the KD group and the control group(P>0.05).No signifi cant complications were noted with paravastatin therapy.Conclusions:Pravastatin improves endothelial function and reduces low-grade chronic infl ammation in patients with coronary aneurysms due to KD.Children with coronary aneurysms due to KD may benefit from statin therapy. 展开更多

Background There are numerous articles on the endothelial progenitor cells (EPCs) in different disease conditions. However, the functional properties of EPCs in acute coronary syndrome (ACS) are still uncertain. Here we aimed to study the number and functions of EPCs in ACS patients. Methods Patients were enrolled with admitted ACS (n=25) and another 25 gender-, age-, atherosclerotic risk factors-matched stable coronary artery disease (CAD) controls. EPCs were defined as CD34+/CD133+/VEGFR-2+ and quantified by flow cytometry. Moreover, functional properties of EPCs including colony-forming unit (CFU), proliferation, migration as well as apoptosis were evaluated and compared between the two groups. Plasma matrix metalloproteinase-9 (MMP-9) was detected in all patients as well. Results The two groups had similar medication and clinical characteristics on admission. The EPCs in ACS patients were more than 2.6 times that in stable CAD subjects (15.6±2.7 vs. 6.0±0.8 /100 000 events, P 〈0.01). CFU was not statistically different between the two groups (10.8±2.9 vs. 8.2±1.8, number/well, P 〉0.05). Furthermore, EPCs isolated from ACS patients were significantly impaired in their proliferation (0.498±0.035 vs. 0.895±0.067, OD value, P〈0.01) and migration capacity (20.5±3.4 vs. 30.7±4.3, number/well, P 〈0.01) compared with controls. Moreover, the apoptosis cell in cultured EPCs was drastically increased in ACS group ((18.3±2.. 1 )% vs. (7.8±0.4)%, P 〈0.01). Conclusions Patients with ACS exhibited apparently increased circulating EPCs as well as cultured apoptosis percentage together with a remarkable impairment of proliferation and migration activities compared with stable CAD subjects. 展开更多

The exploration of coronary microcirculatory dysfunction in diabetes has accelerated in recent years.Cardiac function is compromised in diabetes.Diabetic patients manifest accelerated atherosclerosis in coronary arteries.These data are confirmed in diabetic animal mod-els,where lesions of small coronary arteries have been described.These concepts are epitomized in the classic microvascular complications of diabetes,i.e.blindness,kidney failure and distal dry gangrene.Most importantly,accumulating data indicate that insights gained from the link between inflammation and diabetes can yield predictive and prognostic information of considerable clinical utility.This review summarizes the evidence for the predisposing factors and the mechanisms involved in diabetes,and assesses the current state of knowledge regarding the triggers for inflammation in this disease.We evaluate the roles of hyperglycemia,oxidative stress,polyol pathway,protein kinase C,advanced glycation end products,insulin resistance,peroxisome proliferator-activated receptor-γ,inflammation,and diabetic cardiomyopathy as a "stem cell disease".Furthermore,we discuss the mechanisms responsible for impaired coronary arteriole function.Finally,we consider how new insights in diabetes may provide innovative therapeutic strategies. 展开更多
