Food optimization in order to improve cardiac health and human well-being

Dietary nutrients can be beneficial or detrimental for the heart. For instance, excess dietary saturated fats are known to induce obesity, insulin resistance and type-2 diabetes. Long term administration of these fats associated with its resulting hyperglycemia triggers heart failure, diminished autonomy, and finally death. 

My aim is to determine new dietary strategies designed to protect the heart in such circumstances. Several trails exist, but they must be investigated individually or in combination in order to optimize the best dietary regimen for heart failure patients.

Research Activities

The aim of my researches is to improve cardiac function in order to ameliorate human well-being and health. In this context, I evaluate the effects of several nutrients on cardiac health in physiological and pathological conditions.

One of my focuses of interest is to prevent obesity- and type-2 diabetes-induced heart failure by the way of nutrition. It is possible to mimic this pathology in rats and we also study it in obese human being. After feeding the subjects with appropriate nutrients, we evaluate cardiac function in the in vivo situation, but also in the ex vivo situation with rats. We determine the function of cardiac mitochondria in rats and human beings. We also focalize our attention on the reactivity of coronary micro-vessels, since the cardiac mechanical function and mitochondrial energy metabolism depend on oxygen and substrate supply, and thus on the coronary flow.

Another focus of attention shared with one of my co-worker is the fate of patients subjected to cardiac surgery. It is important to optimize the dietary regimen of these patients in order a good post-surgical recovery occurs. Here again, we work on animal and human myocardia, focalizing our attention on cardiac function (mechanical activity and arrhythmias) and mitochondrial energy metabolism.
