[摘要] When a patient undergoes emergent surgery for type A aortic dissection, in which a tear occurs in the layers of the body’s main artery, there is usually no time to perform an additional study of the state of the patients coronary arteries, the vessels which supply the heart muscle with blood. The authors of this study analysed how often these patients also have disease of their coronary arteries and how often this causes problems. Studying 31 patients with aortic dissection and 123 patients who underwent planned surgery for aortic aneurysm (dilation), they came to the conclusion that coronary heart disease was missed only in very few patients, and that not screening for it before surgery did not decrease survival due to non-aortic causes. They therefore conclude that it is not necessary to delay emergent surgery for aortic dissection to perform coronary angiography to screen for coronary heart disease. However, due to the design of the study and limited patient numbers, further and larger investigations are necessary.
