Myocardial LDH isozyme distribution in the ischemic and hypoxic heart.
Small myocardial specimens were obtained from 12 patients undergoing coronary reconstructive surgery and from 12 patients undergoing surgical correction for cyanotic congenital heart defects. The specimens were analyzed for LDH isozyme distribution. A control analysis was performed on myocardial specimens obtained at the time of surgical correction for acyanotic congenital heart defects in seve...
متن کامل[Myocardial protection to the hypertrophied heart: the eternal challenge].
The myocardial protection allowed great advance in cardiac surgery, decreasing the mortality and making more feasible complex surgeries. Lately, the patient population elected for cardiac procedures has been changing towards elderly patients with ventricular function depressed and myocardial hypertrophy. The myocardial hypertrophy condition represents a great challenge since the beginning of th...
متن کاملLABORATORY INVESTIGATION MYOCARDIAL PROTECTION Protection of hypoxic myocardium by intracoronary administration of verapamil in open-chest dogs
Hypoxic perfusion of the regional myocardium was performed in 34 open-chest dogs. In eight dogs in which the myocardium was perfused with original hypoxic Krebs-Henseleit (K-H) solution for 5 min (group I) there was a marked decrease in adenosine triphosphate content (2.03 + 0.44 ,.mol/g) and an increase in lactate content (8.65 + 2.26 g.mol/g). In myocardium of nine dogs (group II) perfused wi...
متن کاملAttenuation of vasopressin-mediated coronary constriction and myocardial depression in the hypoxic heart.
To investigate the ability of arginine vasopressin (AVP) to compete with metabolic vasodilatory factors in the coronary circulation, we examined the coronary vascular and myocardial effects of AVP in isolated working rat hearts during normoxic and hypoxic perfusion. In normoxic hearts, AVP treatment (777 +/- 67 pg/ml) reduced coronary flow by 38.4 +/- 2.6%. Myocardial function was also signific...
متن کاملNon Working Beating Heart: a new strategy of myocardial protection during heart transplant.
BACKGROUND AND OBJECTIVE We attempt to reduce the ischemic time during implantation of the donor heart in the bicaval bipulmonary orthotopic position using normothermic beating heart and thus, facilitate the transplanted heart adaptation to the recipient. This study presents a small experience about a new strategy of myocardial protection during heart transplant. METHODS In cardiopulmonary by...
