Stroke Recurrence within 2 Years after Ischemic Infarction

Abstract

We Prospectively Studied Stroke Recurrence in 1,273 Patients with Ischemic Stroke Who Were Entered into the Stroke Data Bank. Median Follow-Up Was 13 Months. the 2-Year Cumulative Recurrence Rate among These Patients Was 14.1%. Age, Sex, Race, History of Hypertension, Atrial Fibrillation, or Transient Ischemic Attacks, and Stroke Location Were Not Associated with a Higher Risk of Stroke Recurrence. Patients with an Elevated Blood Pressure, an Abnormal Initial Computed Tomogram, or a History of Diabetes Mellitus Were at a Higher Risk of Stroke Recurrence. in Contrast, Patients with an Infarct of Unknown Cause Were at a Lower Risk of Stroke Recurrence Than Patients with a Denned Stroke Mechanism, Such as Lacune, Embolism, or Atherosclerosis. Amultivaria Te Model Suggests that Patients at the Lowest Risk for Stroke Recurrence Have a Low Diastolic Blood Pressure, No History of Stroke, No History of Diabetes Mellitus, and an Infarct of Unknown Cause. © 1991 American Heart Association, Inc
