  coronary calcification
Osteoprotegerin is not associated with angiographic coronary calcification
      
Whether measurement of coronary calcification also increases the predictive power of coronary events based on cardiovascular risk factors is topic of current research.
      
Therefore, coronary calcification is a promising method for non-invasive detection of asymptomatic subjects at high risk of developing coronary heart disease.
      
Several studies have shown that the amount of coronary calcification is associated with the risk of coronary heart disease.
      
The amount of coronary calcification, as detected by EBT, has a close relation with the amount of coronary atherosclerosis, which is the substrate for the occurrence of myocardial infarction and sudden cardiac death.

45 patients of coronary disease were examined with CT. The extent and morphology of coronary calcification, if present, were described. Coronary angiographies were also done in all of them. Results of the two diagnostic measures were in completes accordance in 36 (80%) cases, near accordance in 2 (4.4%) and not in accordance in 7 (15.6%). The conformation rate of 84.4% warrants the proposition of CT as useful atraumatic measure in the diagnosis of coronary disease.

对临床可疑冠心病、冠心病、心肌梗塞患者45例,作冠状动脉CT检查冠状动脉钙化,并描述CT显示的钙化程度和形态,诊断冠心病,同时与冠状动脉造影对比。结果显示,两者完全符合者36例(80%),基本符合者4例(8.89%)。为冠心病无创诊断提供有效的检查手段。

The Data accrued on 99 Chinese patients among the Initial Batch of subjects scanned at the Matilda Hospital Ultrafast CT unit were analysed retrospectively. It became apparent that the Threshold CT Number could be lowered for Chinese individuals from the usually adopted value of 130 to 100 Hounsfield Units to meaningfully pick up evidence of background Coronary Calcification. It was also found that patients should be segregated into 10year ranges(21-30,31-40,41-50, 51-60)rather than being lumped together...

The Data accrued on 99 Chinese patients among the Initial Batch of subjects scanned at the Matilda Hospital Ultrafast CT unit were analysed retrospectively. It became apparent that the Threshold CT Number could be lowered for Chinese individuals from the usually adopted value of 130 to 100 Hounsfield Units to meaningfully pick up evidence of background Coronary Calcification. It was also found that patients should be segregated into 10year ranges(21-30,31-40,41-50, 51-60)rather than being lumped together randomly to allow a clear distinction in mean CT Score between Males and Females. Furthermore Males tended to have the highest CT Score in middle age while Females did so a decade later.A Case may therefore be made to lower the Basal CT Number in order to facilitate early detection of Calcification, or the tendency to Calcification,in the Coronary Circulation. This in turn may have practical implications for Pre-emptive and Preventive measures against the Atherosclerotic process.

回顾分析Matilda医院超速CT室筛选首批病人中99例中国人资料,很明显从通常采用130-100Hounsfield单位作为检出冠状血管钙化的基数应用至中国人身上其阈值数目需要降低,同时,我们也发现如果病人年龄按每10年范围分组(21-30,30-40,41-50,51-60)而计算其超速CT的钙化指数会较随机男女一起按平均计算更易区分其差异.进一步分析显示,男性中年时候超速CT指数已达最高值,而女性则晚10年方达最高值,因此,为了更易探测冠脉循环内钙化倾向应作出超速CT检出钙化的指数数目.这些实践经验对动脉粥样硬化过程的预测或预防有实际意义.

Purpose: To evaluate the clinical application of ultrafast CT (UFCT) in diagnosis of cardiovascular diseases. Materials and methods: UFCT was achieved in 2 069 patients with various cardiovascular diseases, age ranged from 1 to 82 years. The scanning protocols included single slicee mode (SSM) with slice thickness 1.5, 3.0, 6.0, 10.0 mm, multislice mode (MSM) including cine study and flow study, and continuous volume scan (CVS). In this series of 2 069 cases, there were nonenhancement scans 1 862, contrast enhancement SSM 279, cine study 1 101, flow study 295, and CVS 82. The ECG triggering was used in SSM and MSM. Contrast media were injected by power injector. Results: Among the 2 069 patients with cardiovascular diseases the UFCT technical successful rate was 100%. In the group of the 1 792 patients suspected of coronary heart disease, coronary calcification was detected in 707 (39%). Of 1 792 patients, 90 cases underwent both UFCT and coronary arteriography. The sensitivity and specificity of calcification for diagnosis of coronary stenosis (>50%) were 77% and 80% respectively. Other cardiovascular diseases included valvular diseases in 79 cases, cardiomyopathy in 30, pericardial lesions in 25, cardiac tumors in 11, great vessel diseases in 97, congenital heart diseases in 25 and pulmonary thrombosis and embolism in 10 cases. Conclusion: With scan time as fast as 50~100 millisecond, UFCT can provide high resolution anatomical images of the heart and great vessels without motion artifacts. Both cine and flow studies can assess cardiac function, organ perfusion, and hemodynamics, allowing examination of cardiovascualr pathology in sharp detail for more accurate diagnosis.

目的:评价超高速CT(UFCT)在心血管病诊断中的价值。材料与方法:对2069例心血管病患者进行超高速CT检查。其中平扫1862次,单层增强279次,电影序列1101次,血流序列295次,连续容积扫描82次。结果:疑诊冠心病1792例,其中平扫发现冠状动脉钙化707例(39%),其诊断冠心病的敏感性为77%,特异性为80%。其他包括瓣膜病79例,心肌病30例,心包疾患25例,心脏肿瘤11例,大血管疾患97例,先天性心脏病25例,肺动脉血栓栓塞10例。结论:UFCT扫描可得到高分辨率的心脏大血管解剖影像,并可以评价心脏功能、器官灌注和血液动力学资料,在心血管病理上可以得到更详尽的、正确的诊断
