| Research Abstract |
We need more specific, relevant and predictive biomarkers for not only daily practice but also development of new drugs for the prevention of cardiovascular events. Our research project firstly revealed that not only endothelial function but also smooth muscle responses to NO were impaired in not only diabetic but also IGT patients. These impaired vascular functions were significantly associated with insulin sensitivity. We also showed that elevation of FFA significantly impaired endothelial function, rheological function of myocardial microcirculation, insulin sensitivity and enhanced leukocyte function and angiotensin II forming activity. RAS inhibitors as well as dihydropyridine calcium antagonists significantly but not completely prevented these effects of FFA. We clarified mechanisms for FFA induced endothelial function and insulin resistance and established experimental system for the assessment antiatherosclerotic drugs in human.
