Stroke in the Lehigh Valley: Combined risk factors for recurrent ischemic stroke

We used the Lehigh Valley Stroke Register and a logistic regression model for the odds ratio to study the relative contribution of several factors, considered jointly, to the risk of recurrent ischemic stroke. The factors were hypertension (HT), transient ischemic attack (TIA), myocardial infarction (MI), other heart diseases (OHD), diabetes mellitus (DM), age, and sex. Among these factors MI, OHD, and TIA constituted significantly greater risk than HTN, DM, age, or sex for ischemic stroke recurrence.
