    Overdiagnosis and typicality of symptoms in suspected myocardial infarction

    Both in the context of suspected acute myocardial infarction(AMI)(1) and in the context of its close mimic, suspected pulmonary embolism(PE)(2) there is an appreciable risk of overdiagnosis even when clinicians rely on typicality of AMI symptoms(1) or typicality of PE symptoms the latter as portrayed in clinical decision rules(2). Furthermore, both AMI and PE may have, in common, some atypical features such as atypical retrosternal pain(3)(4), which may sometimes be associated with raised serum troponin(4), and ST segment elevation in the absence of coronary artery occlusion, a feature documented both in Type 2 AMI(5) and also in PE(6). The differential diagnosis of atypical retrosternal pain also includes atypical thoracic aortic dissection(TAD) where the atypical feature may be the absence of back pain in a patient presenting with retrosternal pain.(7). In view of these considerations(3)(4)(5)(6)(7) the time is long overdue for point of care transthoracic echocardiography(TTE) to be incorporated into the IMPACT protocol to facilitate the distinction between AMI, PE, and TAD. TTE would identify stigmata of PE such as right ventricular dilatation, elevated pulmonary artery systolic pressure(8), or even pulmonary emboli in transit through the cardiac chambers . Furthermore, when appropriately focused, TTE can identify "red flags" for TAD such as direct signs of TAD(for example presence of an intimal flap separating two aortic lumens), thoracic aortic d...
