Paper Abstract

Ischemic heart disease is one of the leading reasons of invalidisation and death rate of able-bodied citizens in the world. There are many various surgical and medicamentous methods of its treatment for today, however all these methods have restrictions in application. Our work was directed at initiation possibility clarification of ischemic myocardium revascularization by means of making necrosis with photodynamic therapy. The investigation was carried out in rats with the ischemia artificial made by means of left coronary artery ligation. Level of Photosense photosensitizer accumulation in ischemic and normal rat myocardium zones was defined. Myocardial photodynamic revascularization procedure of ischemic rat myocardium was carried out. Morphological analysis of the myocardium preparations showed the presence of active revascularization of ischemic myocardium after photodynamic therapy. The method of ischemia level estimation based on spectral optical definition of blood oxygen saturation was developed.
