ECG-GATED 16-SLICE CTCA: COMPARISON WITH CATHETER CORONARY ANGIOGRAPHY

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 最终可能导致心脏病发作的冠状动脉疾病是美国死亡的主要原因，在2000年占美国所有死亡的30%（NIH统计）。密歇根州的CAD年龄调整死亡率在美国排名第四。导管冠状动脉造影术是目前最好的诊断工具，可用于检测心脏主要血管中的血流问题，然而，它是一种具有许多相关风险的侵入性手术。我们想确定使用更新更快的64层CT扫描仪（心脏和心脏主要动脉的CAT扫描）进行的CT冠状动脉造影术是否是诊断冠状动脉疾病的准确成像方式。这项研究希望表明，通过使用新的CT扫描技术，我们将能够准确地诊断心脏状况，并且比心脏导管插入术更安全。18岁或以上的男性和女性，如果他们的医生计划进行心脏导管插入术，则可以参加本研究。我们将入组既往接受过或未接受过心脏介入治疗（如血管成形术、支架置入术或冠状动脉搭桥术）的受试者。如果CT冠状动脉造影被证明是一种强大的成像工具，那么它可能对胸痛和非典型胸痛患者（当难以知道胸痛是否源于心脏时）有用。CT的潜在优势包括与心脏导管插入术相比减少辐射剂量，并且更多可能患有心脏病的人可以选择这种非侵入性测试。该测试也可能被证明比心导管插入术更便宜。如果CT对冠状动脉疾病的诊断准确，则可能使用CT来筛查具有冠状动脉疾病高风险因素特征的无症状个体;长期目标是减少急性心脏事件和冠状动脉疾病死亡。'

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Disease of the coronary arteries, which may ultimately lead to a heart attack, is the leading cause of death in the United States, accounting for 30% of all deaths in the United States in the year 2000 (NIH statistics). The state of Michigan has the 4th highest age-adjusted death rate for CAD in USA. Catheter coronary angiography is currently the best diagnostic tool available to detect blood flow problems in the major vessels of the heart, however, it is a invasive procedure with many associated risks. We would like to determine if CT Coronary Angiography using the newer faster 64-slice CT scanner (a CAT Scan of your heart and major arteries of the heart) is an accurate imaging modality for diagnosing coronary artery disease. This study hopes to show that by using new CT scanning techniques we will be able to diagnose heart conditions accurately, and more safely, than heart catheterization. Men and women 18 years of age or older who are scheduled to have a heart catheterization by their physician can participate in this study. We will enroll subjects both who have had or have not had a previous heart intervention such as angioplasty, stent placement or coronary artery bypass surgery. If CT coronary angiography proves to be a robust imaging tool, it may become useful both in patients with chest pain, and atypical chest pain, when it is difficult to know whether the pain in the chest is originating from the heart or not. Potential advantages of CT include decreased radiation dose vs cardiac catheterization and that a greater number of people with possible heart disease may opt for this non-invasive test. The test may also prove to be less expensive than cardiac catheterization. If CT is accurate for the diagnosis of coronary artery disease, it may be possible to use CT to screen asymptomatic individuals with a high risk factor profile for coronary artery disease; with the long term goal of reducing acute cardiac events and death from coronary artery disease.'
