Objectives
Although carotid artery structural variations have been detected by ultrasound, their clinical significance is not fully understood. The objective of this study was to determine whether the angle between the common carotid artery (CCA) and the internal carotid artery (ICA), designated angle α, an ultrasound-detectable carotid artery structural variation, is related to carotid artery intima-media thickness (IMT), a surrogate marker for carotid atherosclerosis.Methods
As a cross-sectional study, we measured angle α in routine carotid artery ultrasounds from 176 subjects (130 men) with atherosclerotic disease/risk factors that attended Kouseiren Hospital in Kagoshima City, Japan between August 2007 and April 2009. We evaluated the correlation between the angle α and CCA- or ICA-IMT.Results
Angle α was weakly correlated with age but significantly correlated with ICA-IMT. The correlation was stronger in subjects with an ICA-IMT ≥ 0.5 mm than in those with an ICA-IMT < 0.5 mm (Right side r = 0.475 vs. 0.246, Left side r = 0.498 vs. 0.301, respectively). Upon multivariate logistic regression analysis, angle α and serum low-density lipoprotein cholesterol were independent explanatory variables for ICA-IMT.Conclusion
Angle α is related to ICA-IMT in subjects with atherosclerotic disease or risk factors in this study.Electronic supplementary material

Restenosis after percutaneous transluminal coronary angioplasty: pathologic observations in 20 patients 总被引:14,自引:0,他引:14

Histopathologic examination was performed in 20 patients undergoing antemortem coronary angioplasty. Thirty-four lesions were dilated and the interval between coronary angioplasty and death ranged from several hours to 4 years. Intimal proliferation of smooth muscle cells, as a major cause of restenosis, was observed in 83% to 100% of 28 lesions examined 11 days to 2 years after coronary angioplasty. In 20 lesions examined within 6 months, proliferating smooth muscle cells were predominantly of the synthetic type and there was abundant extracellular matrix substance chiefly composed of proteoglycans. In eight lesions examined between 6 months and 2 years, contractile type smooth muscle cells were dominant and extracellular matrix was composed chiefly of collagen. In three lesions examined after 2 years, evidence of antemortem coronary angioplasty was hardly identifiable and these lesions were almost indistinguishable from conventional atherosclerotic plaque. These temporal changes in histologic pattern provide a pathologic background for clinical reports that restenosis is predominantly found within 6 months after coronary angioplasty. Morphometric analysis revealed that the extent of intimal proliferation was significantly greater in lesions with evidence of medial or adventitial tears than in lesions with no or only intimal tears. 相似文献

Summary Five hundred and seven subjects with postprandial glycosuria underwent a 50 g oral glucose tolerance test in an epidemiological survey of diabetes mellitus carried out in 1964–1965 in the town of Osaka, Japan. The oral glucose tolerance test was repeated 7 years later in 207 (40.8%) of the subjects. The results of the initial and the follow-up test were classified into three categories according to the new WHO criteria: normal, impaired glucose tolerance and diabetes. Most of the diabetic subjects (84.8%) remained unchanged between the initial and follow-up test. Of the subjects with impaired glucose tolerance at the time of the initial test, 38.5% showed diabetes in the follow-up test, while another 38.5% returned to normal. On the other hand, 13.5% of the normal subjects in the initial test developed impaired glucose tolerance or diabetes in the follow-up test. The rate of worsening to diabetes was related closely to the 2-h blood glucose value at the initial test. In addition, the rate of worsening was higher in males and obese subjects than in females and non-obese subjects. A multiple logistic analysis indicated that the fasting and 2-h glucose values were significantly predictive of worsening to diabetes. 相似文献

Endoscopic pancreatic sphincter balloon dilation for effective retrieval of pancreatic duct stone 总被引:9,自引:0,他引:9

To facilitate pancreatic stone retrieval, four patients with chronic pancreatitis and pancreatic stones underwent endoscopic pancreatic sphincter balloon dilation (EPSBD) rather than pancreatic sphincterotomy. Extracorporeal shock wave lithotripsy combined with endoscopic removal was carried out in three patients. Stone removal following EPSBD was completely successful in all four patients. Patients showed no severe complications during the dilation procedure. In one patient, to prevent pancreatitis, an endoscopic nasopancreatic drain was placed for 1 week after EPSBD. Compared with pancreatic sphincterotomy, EPSBD can be performed safely in patients with chronic pancreatitis to assist in the extraction of pancreatic duct stones. Use of the EPSBD procedure in cases of chronic pancreatitis provides a useful approach to improve endoscopic clearance of pancreatic duct stones. 相似文献

We investigated the prevalence of Helicobacter pylori infection and the effect of its eradication in a series of 61 chronic ITP patients. H. pylori infection was found in 53 (86.9%) of 61 ITP patients. H. pylori eradication were performed in 44 infected ITP patients and succeeded in 28 (63.6%) patients. 20 (71.4%) of those 28 patients had platelet recovery and 15 (53.6%) patients achieved a remission, and that effect continue (about 2 years). And we investigated relation with ITP and upper gastrointestinal disease. 2 (3.8%) of 53 H. pylori infected cases were gastric ulcer, 1 (1.9%) was duodenal ulcer and 1 (1.9%) was gastric cancer. All cases were chronic atrophic gastritis, and localized atrophic cases achieved a remission after eradication of H. pylori. 相似文献

Relationship between efficacy of antiarrhythmic drug therapy and structural remodeling in patients with paroxysmal atrial fibrillation 总被引:1,自引:0,他引:1

OBJECTIVES: To evaluate whether the response to antiarrhythmic drug therapy in patients with paroxysmal atrial fibrillation affects the development of structural remodeling in the left atrium and ventricle. METHODS: This study included 230 patients (158 men and 72 women, mean age 67 +/- 11 years) in whom antiarrhythmic drug therapy was attempted for > or = 12 months to maintain sinus rhythm (mean follow-up period 45 +/- 27 months). The patients were divided into three groups according to the response to antiarrhythmic drug therapy: group A consisted of 78 patients without recurrence of atrial fibrillation, group B consisted of 87 patients with recurrence of atrial fibrillation and electrical and/or pharmacological cardioversion to restore sinus rhythm, and group C consisted of 65 patients with permanent conversion despite antiarrhythmic drug therapy. RESULTS: In group A, left atrial dimension (LAD), left ventricular end-diastolic dimension (LVDd), and left ventricular ejection fraction (LVEF) did not change after antiarrhythmic drug therapy. In group B, LAD increased significantly after antiarrhythmic drug therapy (from 32.6 +/- 6.4 to 36.0 +/- 6.5 mm, p < 0.01), Whereas either LVDd or LVEF did not change after antiarrhythmic drug therapy. In group C, LAD increased significantly after antiarrhythmic drug therapy (from 37.3 +/- 7.0 to 40.5 +/- 7.9 mm, p < 0.01) and LVEF was significantly reduced after antiarrhythmic drug therapy (from 69.4 +/- 6.2% to 66.5 +/- 8.9%, p < 0.05). LVDd did not change after antiarrhythmic drug therapy. The plasma concentration of human atrial natriuretic peptide during sinus rhythm at the initiation of antiarrhythmic drug therapy in group A (30.5 +/- 26.7 pg/ml) was significantly lower than those in group B (48.0 +/- 49.7 pg/ml) and group C (49.7 +/- 39.5 pg/ml). CONCLUSIONS: The development of structural remodeling in human myocardium can be prevented with antiarrhythmic drug therapy if sinus rhythm is maintained without recurrence of atrial fibrillation in patients with paroxysmal atrial fibrillation. 相似文献
