Methods and results - From 1 January 1995 to 31 July 2006, 531 patients admitted to our hospital with the initial or later diagnosis of acute aortic dissection were reviewed. Two hundred and thirty-nine patients were diagnosed as Stanford type A aortic dissection with a mortality rate of 17% (41/239). Eleven (5%) of the 239 patients had initial presentation of AMI (chest pain and elevation of cardiac enzymes, with or without ST-segment elevation) and a high mortality rate of 36% (4/11). All six patients with ST-segment elevation underwent coronary angiography without awareness of type A aortic dissection; three patients were detected to have eccentric aortic regurgitation by transthoracic echocardiography (TTE) before angiography but type A aortic dissection was neglected at that time. Three of the five patients without ST-segment elevation also had eccentric aortic regurgitation by TTE before the confirmative diagnosis was made; prompt suspicion of type A aortic dissection was assisted with an elevation of D-dimer value in one of these three patients.The presence of eccentric aortic regurgitation by TTE, and the increased D-dimer value provided hints of the coexistence of AMI and type A aortic dissection. Conclusions - Type A aortic dissection manifesting as AMI is a catastrophe in disguise. Prompt checks of TTE and the D-dimer value would bring the hidden diagnosis of acute aortic dissection more to the forefront. |
