What is the incidence of left ventricular thrombus formation after ST-segment-elevation myocardial infarction?
The incidence of left ventricular thrombus formation after ST-segment-elevation myocardial infarction is not well established. Studies have reported varying incidence rates ranging from 8.4 to 43%. Factors associated with an increased risk of thrombus formation include older age, larger infarct size, diabetes, and history of prior infarction. Left ventricular thrombus formation has also been associated with an increased risk of embolization and stroke. Despite this, the risk of stroke with LV thrombus formation is not well established. Studies have reported varying rates of stroke ranging from 5.7 to 15.6%.
