The Value of Dual-source 64-Slice CT Coronary Angiography in the Assessment of Patients Presenting to an Acute Chest Pain Service - 11/08/11
Résumé |
Background |
The absence of radiological evidence of plaque on computed tomographic coronary angiography (CTCA) reliably excludes obstructive coronary artery disease.
Methods |
We studied patients who presented to our emergency department with chest pain and were admitted to our chest pain assessment service. If they were free of pain and without high-risk features of myocardial ischaemia including elevation of serum biomarkers they underwent CTCA and performed a standard treadmill exercise test.
Results |
Eighty-nine patients aged 56.3±8.6 years were admitted. Eleven of them had selective angiography; CTCA identified all who had obstructive disease. More than half of the 85 patients who had normal values of cardiac troponin and of the 75 with a negative exercise test had radiological evidence of disease.
During follow-up for 355±72 days none died, suffered myocardial infarction or required coronary artery surgery: two with obstructive disease underwent percutaneous coronary intervention 1 and 7 days after the index study.
Conclusions |
The CTCA findings were significantly correlated with those of selective angiography and with troponin status and increased the ascertainment of coronary artery disease in a cohort of patients at low risk for clinically significant ischaemic heart disease.
