Our recent studies have underscored the importance of mitochondrial oxidative stress as a major mechanism leading to cardiac dysfunction in obesity and diabetes. Recent studies have focused on: (1) The contribution of excessive myocardial insulin signaling in the myocardium in accelerating left ventricular remodeling in the hypertrophied and failing heart. (2) The regulation of myocardial autophagy by insulin signaling. (3) The mechanisms by which myocardial lipid overload alters autophagy in cardiac muscle (4) The role of altered mitochondrial dynamics in the pathophysiology of cardiac dysfunction in obesity and insulin resistant states. (5) Mechanisms for increased thrombosis in obesity and insulin resistant states.
