Geriatric acute myocardial infarction: a challenge to recognition, prompt diagnosis, and appropriate care.
The presentation of an AMI in the older person is often atypical, with a lower incidence of classic chest discomfort but increasing incidence of dyspnea, syncope, stroke, and acute confusion. Atypical presentation is especially common in those 85 years and older. The altered pattern of symptoms predisposes the elderly to a delayed or missed diagnosis. Delay in diagnosis may also occur when the ECG is nondiagnostic. In addition, enzyme elevations may be lower and fail to reflect the extent of myocardial damage. Thus, among the greatest challenges confronting critical care nurses is that of caring for elderly patients presenting with atypical AMI and concomitant polypathology. Nurses who are well informed about the normal age-related changes in the cardiovascular system contribute to more accurate and timely diagnosis and treatment of AMI in the elderly.
