چکیده
INTRODUCTION The objective of this study was to evaluate the incidence of death, cardiovascular events and the use of later non-scheduled imaging for coronary artery disease (CAD) in patients suspected for CAD and discharged without a need for further examination or treatment from an outpatient clinic following coronary computed tomography angiography (CCTA). MATERIAL AND METHODS This was a retrospective cohort study among patients discharged from an outpatient clinic after CCTA at our institution during 2009 and 2010. Follow-up was performed using nationwide Danish registers. RESULTS A total of 683 (68.2%) out of 1001 patients were discharged from the outpatient clinic after CCTA with no need for further examination. These patients were included in our study. After a median follow-up of 37 months, a low all-cause mortality of 3.7 per 1,000 person-years was found. There was only one case of acute myocardial infarction and no cases of death related to cardiovascular disease. A total of 5.0% of the patients later underwent non-scheduled imaging, predominantly invasive coronary angiography. No patients had revascularisation performed during the study period. CONCLUSION Patients with suspected CAD discharged after CCTA with no need for further examination have a favourable cardiovascular prognosis. FUNDING Not relevant. TRIAL REGISTRATION Not relevant.

Intramural coronary arterial course is associated with coronary arterial stenosis and prognosis of major cardiac events.
OBJECTIVE The clinical significance of an intramural course (or bridging) of the coronary artery remains controversial. We investigated the relationship between intramural coronary arteries (ICAs) and coronary stenosis and prognosis of subjects with ICA. METHODS AND RESULTS ICA and coronary stenosis were assessed by multidetector computed tomography coronary angiography. ICAs in the left ante...

Differences in Prevalence, Extent, Severity, and Prognosis of Coronary Artery Disease Among Patients With and Without Diabetes Undergoing Coronary Computed Tomography Angiography
OBJECTIVE We examined the prevalence, extent, severity, and prognosis of coronary artery disease (CAD) in individuals with and without diabetes (DM) who are similar in CAD risk factors. RESEARCH DESIGN AND METHODS We identified 23,643 consecutive individuals without known CAD undergoing coronary computed tomography angiography. A total of 3,370 DM individuals were propensity matched in a 1-to...
متن کاملDynamic myocardial perfusion imaging by dual-source computed tomography.
We report a dual-source computed tomography study of dynamic and quantitative myocardial perfusion in a 44-year-old patient with previous documented coronary artery disease. Quantitatively, the tomography showed myocardial perfusion deficit in the territories with significant coronary stenosis, confirmed by computed tomography angiography and conventional angiography. Dual-source computed tomog...
متن کاملMulti-slice computed tomography: Can it adequately rule out left main coronary disease in patients with an intermediate probability of coronary artery disease?
BACKGROUND Multi-slice computed tomography (MSCT) is a fast-growing technology that permits a non-invasive, yet reliable, assessment of coronary atherosclerosis. We sought to explore the diagnostic accuracy of MSCT angiography in the detection of significant stenosis of the left main coronary artery (LMCA) in a series of patients with an intermediate pre-test likelihood of coronary artery disea...
