"There are several possible reasons for the stronger effect of insulin resistance on the risk of ischemic stroke than of myocardial infarction in the present study compared within other studies," the authors write. It may be because individuals with a history of heart attack were excluded from this study, or because factors associated with insulin resistanceincluding high blood pressure, high triglyceride levels and low HDL or "good" cholesterol levelsare more significant risk factors for stroke than for heart attack.
"These findings emphasize the need to better characterize individuals at increased risk for ischemic stroke and the potential role of primary preventive therapies targeted at insulin resistance," the authors conclude.

Editorial: Insulin Resistance Can Be Used to Refine Risk Stratification
"The implications of these findings are exciting if insulin resistance can be proven to be a causal risk factor for stroke (rather than a marker of increased risk) because insulin resistance cannot only be measured but also treated," write Graeme J.
