Common carotid artery and internal carotid artery intima-media thicknesses (IMT) are associated with coronary heart disease (CHD) and increase with age. Using age, sex, and race/ethnicity IMT percentiles may improve CHD prediction when added to Framingham risk factors and coronary artery calcium score. We study these possibilities in the Multi-Ethnic Study of Atherosclerosis (MESA), a multi-ethnic cohort of whites, Chinese, blacks, and Hispanics. ⋯ A carotid IMT score based on normative data incrementally adds to Framingham risk factors and a positive calcium score in predicting first-time CHD in an ethnically diverse cohort.

Insulin resistance is associated with an increased risk of cardiovascular events in the general population. This study aimed to estimate the association between post-glucose load measures of insulin resistance and prognosis of nondiabetic patients with ischemic stroke. ⋯ In this large-scale registry, post-glucose load measures of insulin resistance with the ISI(composite) and the ISI0,120 were associated with 12-month poor outcomes of nondiabetic patients with ischemic stroke.

Contrast-induced acute kidney injury (CI-AKI) was traditionally defined as an increase in serum creatinine (sCr) after contrast media exposure. Recently, serum cystatin C (sCyC) has been proposed as an alternative to detect acute changes in renal function. The clinical implications of combining sCyC and sCr to diagnose CI-AKI remain unknown. ⋯ Combining sCyC and sCr to diagnose CI-AKI would be beneficial for risk stratification and prognosis in patients after contrast media exposure.
