Abstract:
The myocardial nutrition after myocardial revascu-larization was studied in 14 rabbits with the aid of Nd-YAG laser, before Ligation of the anterior descending branch of the left coronary artery (only ligated LAD in 4 rabbit), the rabbits were seperatively Killed 3 or 5 weekafter operating. Myocardial samples were abtained in the parti of 0 - 2,2 - 4,4 - 6mm from laser hole. Sample numbers were 30 in myocardial revascularization group (MRG); 20 in myocardial Infarction group(MIG); 20 in normal group (NG). Amount of ATP and CP in myocar-dia were determined with luciferase. Resalts.ATP and CP near laser holes were normal 3 week late. This far from laser holes was lower than that of normal myocardia 5 week late. Recover of CP amount was slower than that of ATP amount. Inclusion, myocardial revascularization can play role in myocardial nutrition.
