Methods This is a prospective observational study on 157 patients 100 cardiac surgery patients 57 carotid endarterectomy patients . Data were collected on factors potentially related to baseline INVOS values. Data were analyzed with student s t-test Chi-square Pearson s correlation or Linear Regression as appropriate. Results 100 cardiac surgery patients and 57 carotid surgery patients enrolled. Compared to cardiac surgery carotid endarterectomy patients were older 71.05 8.69 vs. 65.72 11.04 P 0.001 with higher baseline INVOS P 0.007 and greater stroke frequency P 0.002 . Diabetes and high cholesterol were more common in cardiac surgery patients. Right side INVOS values were strongly correlated with left-side values in carotid r 0.772 P 0.0001 and cardiac surgery patients r 0.697 P 0.0001 . Diabetes and high cholesterol were associated with significantly P 0.001 lower INVOS and smoking was associated with higher INVOS values in carotid but not in cardiac surgery patients. Age sex CVA history Hypertension CAD Asthma carotid stenosis side and surgery side were not related to INVOS. Multivariate analysis showed that diabetes is strongly associated with lower baseline INVOS values bilaterally P 0.001 and explained 36.4 of observed baseline INVOS variability in carotid but not cardiac surgery. Conclusion Compared to cardiac surgery carotid endarterectomy patients are older with .
