title: Acute MI. Age-related presentations and treatment options.
abstract: At least 60% of all acute myocardial infarctions (AMIs) occur in patients age 65 and older and about one-third in patients older than age 75. The presentation of AMI is modified by age-related changes in endothelial function, smooth muscle cell activity, diastolic function, and responses to circulating catecholamines. Atypical presentations are common in the older patient and require the physician to maintain a high index of suspicion for AMI. ECG findings of ST-segment depression make many older patients ineligible for reperfusion by thrombolytic therapy. Acute and post-MI medical therapies are underused in the older population and should be individualized, based on the presence of comorbid conditions.
