The 95% CIs for risk for all three polymorphisms were non-overlapping comparing ischemic stroke with ischemic heart disease, although restricting cardiac datasets to those in which Caucasian ethnicity was definitely specified results in marginal overlap for glycoprotein IIIa Leu33Pro (ischemic heart disease OR: 0.99 – 1.09) and angiotensinogen M235T (coronary stenosis OR: 1.0 – 1.16). This evidence concerns the gene AGT and coronary stenosis.
