Is there a concordance between carotid and penile cavernosal artery intima-media thickness in patients with erectile dysfunction?

This study aimed to investigate the predictive accuracy of carotid and cavernosal Doppler ultrasound findings for discriminating patients with vasculogenic erectile dysfunction (ED). Fifty patients with complaints of ED were included. B-mode ultrasound of bilateral carotid arteries were performed and peak systolic velocity (PSV), end-diastolic velocity (EDV) and intima-media thickness (IMT) values were measured. Afterwards, corresponding values of cavernosal arteries were obtained by penile color duplex ultrasonography (P-CDU). Of total 50 patients, 29 (58%) were included in vasculogenic ED group and 21 (42%) in non-vasculogenic ED group according to P-CDU findings. There was a significant difference between groups for cavernosal IMT (P=0.012) but not for carotid IMT (P=0.601). When patients were reclassified according to carotid IMT values (IMT of the first group <0.9?mm and the second ≥0.9?mm), carotid PSV and EDV values were different (P=0.033 and 0.018, respectively). Cavernosal PSV and EDV displayed no difference (P=0.816 and 0.123) while cavernosal IMT and percent change of cavernosal caliper were significantly different (P=0.014 and 0.018). Carotid PSV and EDV successfully mirrored respective measurements in cavernosal artery. However, carotid IMT failed to demonstrate such a correlation. Cavernosal IMT seems promising as an additional tool in the evaluation of cavernosal function.

Analysis of cardiovascular risks for erectile dysfunction in Chinese patients with type 2 diabetes mellitus lacking clinical symptoms of cardiovascular diseases

BackgroundErectile dysfunction (ED) is common but usually underdiagnosed in diabetics. The correlation between different vascular lesions and ED in diabetics without clinical cardiovascular symptoms is unknown. The aim was to explore the association between cardiovascular risks and ED in Chinese type 2 diabetic men lacking clinical performance.MethodsErectile function of patients with type 2 diabetes was assessed by the 5-item International Index of Erectile Function (IIEF-5) questionnaire. The data of clinical characteristics and vascular lesions at carotid and lower limb sites assessed by the Doppler ultrasound were collected to evaluate diabetes- metabolic indices. Univariate and multivariate analyses were conducted to find statistical correlation between cardiovascular risks and diabetic ED.ResultsA total of 71.21% reported suffering from ED. Lower limb plaques were more common (45.38%) than carotid district (35.62%) in diabetes. Men with ED had higher carotid intima-media thickness (IMT) (P<0.001) and the presence of lower limb plaques (P<0.001) compared with men without ED. After adjusting for age, diabetic duration, blood pressure (BP) and antidiabetic medication, carotid IMT greater than 0.75 mm (P<0.001) and the presence of lower limb plaques (P=0.051) remained associated with the presence of ED and its severity. Compared with isolated atherosclerosis at carotid or lower limb district, vascular lesions at any site and both sites were more correlative with ED presence (all P<0.001).ConclusionsThe prevalence of ED is high among Chinese diabetic men. A higher carotid IMT and the presence of lower limb plaques indicate a tight correlation between peripheral atherosclerosis and diabetic ED. ED may be the only clinical association of symptomatic cardiovascular diseases (CVDs) in diabetes. It is significant to screen ED to prevent the further development of severe symptomatic CVDs.

Tight relations between coronary calcification and atherosclerotic lesions in the carotid artery in chronic dialysis patients

Aim: Both vascular calcification and atherosclerosis are highly prevalent in patients with end‐stage renal disease (ESRD) and have been associated with increased cardiovascular morbidity. Because those two phenomena might be only coincidentally related in chronic haemodialysis (HD) patients, in this study, coronary artery calcification (CAC), common carotid artery intima media thickness (CCA‐IMT) and thickness of atherosclerotic plaques in the carotid artery were simultaneously measured. Methods: In a cross‐sectional study of 47 HD patients (31 male, mean age 56.8 ± 11.4 years, and 16 female, mean age 56.0 ± 7.5 years) without history of major cardiovascular complications. CCA‐IMT and presence and thickness of atherosclerotic plaques were measured with ultrasound and CAC with multidetector computed tomography. Results: The CAC were present in 70.2% of patients. The mean CAC was 1055 ± 232, the mean CCA‐IMT was 0.96 ± 0.21. The atherosclerotic plaques in the common carotid arteries were visualized in 38 patients (80.1%), the mean thickness of the atherosclerotic plaque was 1.61 ± 0.8 mm. We found a significant positive correlation between CAC and CCA‐IMT (r = 0.70, P < 0.001). The thickness of atherosclerosis plaque positively correlated with CAC as well as with CCA‐IMT (r = 0.60, P < 0.001 and r = 0.7, P < 0.003, respectively). Conclusion: The study revealed close relationships between CAC, intima media thickness and the thickness of atherosclerotic plaques in dialysis patients. It may indicate that both vascular calcification and atherosclerotic lesions frequently coexist in patients with ESRD and that the intima media thickness could serve as a surrogate marker of vascular calcification.     

Carotid intima-media thickness in patients with abdominal aortic aneurysms.

OBJECTIVE: The contribution of atherosclerosis to the development of Abdominal Aortic Aneurysms (AAA) is still controversial. Ultrasound scans can detect intima-media thickening of the carotid arteries as an early sign of atherosclerosis. The aim of this study was to investigate whether patients with Abdominal Aortic Aneurysms (AAAs) have thickened carotid IMT as patients with atherosclerotic peripheral arterial disease (PAD). METHODS: With high-resolution B-mode ultrasonography, the intima-media thickness (IMT) in the carotid arteries (right and left common carotid artery) was measured in AAA patients and compared with that of age and sex-matched patients with atherosclerotic peripheral arterial disease (PAD). A third group of healthy age and sex- matched control subjects were included for comparison. The corresponding carotid artery lumen was also determined in all groups. Comparison of the three groups was made by ANOVA. RESULTS: Fifty-eight AAA patients and 69% were men (mean age of 72.3 years) were studied. Aged and sex-matched groups comprised of 111 PAD patients and 71 healthy. The mean carotid IMT was highest in PAD patients (1.036+/-0.18mm). The values of controls and AAA patients were similar and significantly lower than that of atherosclerotic patients (0.875+/-0.11mm and 0.812+/-0.53mm respectively, both p<0.005 vs. PAD). Narrowing of the corresponding lumen was found in PAD patients compared with that of AAA patients, but no difference can be seen between healthy subjects and AAA patients. The mean carotid IMT was greater in men (P<0.05) in all studied groups, but no similar gender specificity was found in the lumen diameter. CONCLUSIONS: This study shows that the carotid artery IMT of AAA patients is similar to healthy subjects, but not as thick as patients with atherosclerotic disease. As carotid (IMT) is a surrogate marker of atherosclerosis, the findings support the notion that the formation of AAA may not be fully atherosclerosis-dependent. Gender may be a confounding factor for carotid intima-media thickening.     

Viscoelastic properties of normal and atherosclerotic carotid arteries.

BACKGROUND: remodelling of the arterial wall occurs with ageing, even in the absence of atherosclerotic risk factors. With increasing age, arteries dilate, thicken, and get stiffer. The aim of this study was to correlate carotid artery stiffness with wall thickness and plaque presence between healthy individuals and patients with early and advanced atherosclerosis. METHODS: twenty healthy volunteers, 40 carotid segments and 90 patients, 174 carotid segments, with vascular disease were included in the study. The carotid artery was imaged longitudinally and measurements of the intimal-medial thickness (IMT) and plaque were obtained. Systolic and diastolic blood pressures were taken from each arm. The carotid artery stiffness (pressure-strain elastic modulus, Ep) was calculated in all sites from the changes in pressure and diameter. M-mode was used to detect the diameter change (systolic to diastolic) over five cardiac cycles. RESULTS: in the healthy volunteers there was no evidence of plaque or increased IMT. The mean IMT was significantly higher in the patients compared to control (0.83+/-0.27 mm vs. 0.54+/-0.08 mm, p <0.0001). The IMT had a poor correlation with Ep at lower thickness (r=0.24, p=0.08) but this association became stronger with increasing thickness (r=0.62, p<0.001). Arterial segments with an IMT 5 0.88 mm became significantly stiffer compared to the controls (p<0.001) and to patients with an IMT<0.88 mm (p <0.01). Carotid Ep was markedly greater in arterial segments with plaques than in those with increased IMT (p <0.001) and the controls (p<0.0001). CONCLUSIONS: carotid wall areas with small increase in IMT have a poor correlation with carotid artery stiffness. The carotid stiffness increases in areas with marked wall thickening and particularly in segments with plaque. The simultaneous study of vessel-wall elastic behaviour with IMT and plaque changes may increase our understanding of atherosclerotic progression and wall remodelling.

Circulating endothelial progenitor cells and endothelial function after chronic Tadalafil treatment in subjects with erectile dysfunction

We evaluated the effect of a chronic treatment with Tadalafil on progenitor cells (PCs) number and endothelial function in patients with erectile dysfunction (ED) with or without cardiovascular risk factors. Twenty-six subjects with ED and 23 aged matched controls were studied. All subjects underwent blood tests, International Index of Erectile Function (IIEF-5), Nocturnal Penile Tumescence Rigidity Monitoring test (NPTRM), brachial artery flow-mediated dilation (FMD) and PCs count. International index of erectile function, FMD and PC count were re-evaluated in all subjects at the end of Tadalafil and placebo treatment. With respect to controls patients had lower basal FMD (P < 0.05) and basal PCs (P < 0.05). Treatment with Tadalafil determined a significant increase in PCs (P < 0.001) and FMD (P < 0.001) with respect to basal level. Positive correlation was found between basal FMD and PCs (P < 0.05) and between basal FMD and PCs increase after Tadalafil treatment (P < 0.05). Tadalafil promotes a mobilization of PCs and improves endothelial function in ED patients.

Carotid intima-media thickness and plaques in hemodialysis patients

Atherosclerosis is accelerated in hemodialysis patients. Using B-mode ultrasonography, we compared intima-media thickness (IMT) and the prevalence of plaques in the common carotid and internal carotid arteries in 28 randomly selected hemodialysis patients with that in 28 age- and sex-matched normal controls. The IMT values of the common carotid and internal carotid arteries were higher in hemodialysis patients than in controls with more hemodialysis patients having plaques. In hemodialysis patients, there was a relationship between age and IMT in the common carotid arteries, in the area of bifurcation, and in the internal carotid arteries. We found no relationship between IMT and atherosclerotic risk factors or duration of hemodialysis treatment. IMT at all sites correlated with the number of plaques. Age was the only significant determinant for number of plaques. The results indicate that hemodialysis patients showed advanced atherosclerosis in the carotid arteries compared with age- and sex-matched normal subjects.

目的:本文通过观察不同剂量他达拉非(希爱力)对于勃起功能障碍(ED)患者的治疗效果,探索他达拉非剂量与阴茎血流彩色多普勒参数之间的关系。方法:对136例ED患者在治疗前后进行IIEF-5评分同时用彩色多普勒超声联合阴茎血管活性药物前列腺素(PGE1)注射试验,检测阴茎双侧海绵体动脉的收缩期最大流速(PSV)。根据治疗前不同的PSV值,随机分为4组,采用了疗程为4周的隔日晚餐后口服不同剂量他达那非的用药方案。A组:PSV>15 cm/s,选择10 mg剂量;B组:PSV>15 cm/s,选择5 mg剂量;C组:PSV<15 cm/s,选择10 mg剂量;D组:PSV<15 cm/s,选择5 mg剂量。结果:治疗4周后,经统计学分析,4组IIEF-5评分以及阴茎双侧海绵体动脉的PSV与治疗前相比均有显著提高(P<0.01)。而且治疗4周后,A组与B组IIEF-5评分以及阴茎双侧海绵体动脉的PSV之间没有明显差异;C组却显著高于D组(P<0.01)。结论:隔日口服不同剂量的他达那非均能有效提高ED患者阴茎海绵体动脉的收缩期最大流速,改善患者的勃起质量。PSV>15 cm/s的ED患者可选择小剂量5 mg隔日;PSV<15 cm/s的ED患者尽量选择较大剂量10 mg隔日,以取得更好的疗效。     

Atherosclerosis in patients with analgesic nephropathy treated with haemodialysis

SUMMARY: Accelerated atherosclerosis was reported to be associated with chronic analgesic consumption, but most studies were retrospective, and individual findings have almost never been controlled with regard to other atherosclerotic risk factors. Ten haemodialysis patients with analgesic nephropathy (group I) and 19 haemodialysis patients where renal failure was not caused by analgesic nephropathy (group II) were included in the study. All patients were female without diabetes. Using B-mode ultrasonography, we compared intima-media thickness (IMT) in the carotid arteries and plaque occurrence, and their thickness in group I with that in group II. the possible differences in atherosclerotic risk factors in both groups were also investigated. In group I, the average age was 60.2 years, and the average dialysis treatment was 55.7 months. In group II, the average age was 54.6 years, and the average duration of dialysis treatment was 50.4 months. We found no statistically significant difference in the age and duration of dialysis treatment between groups I and II. the IMT values of the carotid arteries (0.97 vs 0.78 mm; P = 0.027) were significantly higher in group I. More patients had plaques in group I (90 vs 57.9%), and the number of plaques ( P = 0.037) and their thickness ( P = 0.043) were significantly higher in this group. There was no statistically significant difference in the atherosclerotic risk factors between groups I and II. the results indicate that patients with analgesic nephropathy treated with haemodialysis showed advanced atherosclerosis compared with other haemodialysis patients, despite no difference being found in the atherosclerotic risk factors between these patients.     

老年慢性肾脏病患者骨密度水平与颈动脉IMT的相关性研究

目的研究不同分期老年慢性肾脏病(CKD)患者颈动脉粥样硬化与骨密度水平的关系,为CKD不同分期老年人群骨质疏松症与心血管疾病的防治提供相关的理论及临床指导。方法以本院门诊及住院的老年CKD非透析治疗患者为研究对象,健康老人为对照组,采用双能X线吸收法(DXA)测定腰椎骨和股骨区的骨密度水平(BMD),同时采用彩色多普勒超声探查颈动脉内膜-中层厚度(IMT)及粥样斑块的情况;应用SPSS18.0软件包,统计分析骨密度水平与颈动脉粥样硬化的关系。结果 CKD患者骨密度水平均比健康对照组显著降低(-2.4SD±0.18比-0.8SD±0.24,P0.01);在非透析CKD患者中,肾小球滤过率(GFR)与骨密度水平呈现正相关,各组间比较差异有统计学意义(P0.05或P0.01);CKD患者颈动脉内膜中层厚度(IMT)(0.78±0.21比0.71±0.24 mm,P0.01)及斑块形成(66.6%比36%,P0.01)、颈动脉硬化的患病率(66.6%比36%,P0.01)较健康对照组均显著升高;直线相关分析显示,骨密度水平与hs CRP、TG、血磷、i PTH、血红蛋白(Hb)呈正相关(P0.05或P0.01),与GFR、血钙、血白蛋白(SAlb)、IMT、斑块形成、颈动脉硬化的患病率呈负相关(P0.05或P0.01);多因素逐步回归分析显示,年龄、收缩压、糖尿病、吸烟、药物以及BMD是CKD患者颈动脉病变的独立危险因素。CKD患者IMT比对照组显著增厚(P0.01),其颈动脉粥样斑块总检出率66%,对照组的总检出率仅为36%(P0.01),CKD中晚期患者的颈动脉IMT增厚和粥样斑块的阳性率更为明显(P0.05)。结论各期CKD患者骨密度水平均显著降低,且与颈动脉病变相关,骨质疏松可能是CKD患者并发动脉粥样硬化的危险因素之一。动脉粥样硬化斑块的形成,与患者的年龄、血脂、CKD不同分期及骨密度均有显著相关性,骨质疏松的危险因素与之亦有共同点。骨质疏松与动脉粥样硬化高度相关,二者互为因果。

Relationship between oxidative stress parameters and atherosclerotic signs in the carotid artery of stable renal transplant patients

Reactive oxygen species (ROS) may participate in atheroma plaque formation, which may be noninvasively diagnosed by Doppler ultrasound of carotid artery. We sought to determine the relationship between the presence of carotid artery lesions and oxidative parameters to identify factors that may influence these lesions in renal transplant patients. Fifty renal transplanted patients with stable renal function and without diabetes mellitus were studied for more than 1 year posttransplantation. Echo Doppler examination of the carotid artery was performed to assess the intimal media thickness (IMT), atheroma plaques, calcification, and stenosis. Data were collected on oxidative parameters: malondialdehyde (MDA), glutathione peroxidase (GPx), catalase, superoxide dismutase (SOD), glutathione reductase (GR), and lipid profile. The serum GPx level among patients without atheroma plaques, calcification, or stenosis was higher than in those with ultrasound signs. The LDL cholesterol fraction was lower in patients with no ultrasound signs of atherosclerotic lesions; total cholesterol values showed the same behavior. In conclusion, transplanted patients with atheromatous plaques, calcification, and carotid stenosis have a greater degree of hypercholesterolemia and lower antioxidant activity (lower GPx). Recipient age was the principal risk factor for the presence of increased IMT, atheroma plaque, calcification, and/or stenosis of carotid artery in renal transplant patients.
