[The effect of creatine phosphate in patients after surgery in ischemic heart disease]
Insights
Creatine phosphate supplementation during heart surgery may reduce ventricular arrhythmias and cardiac enzyme release, particularly in patients with impaired left ventricular function. This cardiac protection strategy warrants further investigation for coronary heart disease patients.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Biochemistry
Context:
- Coronary heart disease (CHD) necessitates surgical intervention, often involving cardiopulmonary bypass.
- Maintaining myocardial integrity during cardiac surgery is crucial for patient outcomes.
- Extracorporeal circulation and cardioplegic solutions are standard in cardiac procedures.
Purpose:
- To evaluate the efficacy of creatine phosphate in protecting the myocardium during coronary heart disease surgery.
- To assess the impact of creatine phosphate on cardiac enzyme release, arrhythmias, and hemodynamic stability.
- To investigate the effects of creatine phosphate on myocardial morphology and function post-surgery.
Summary:
- Fifty patients undergoing coronary heart disease surgery were divided into control and creatine phosphate groups (added to extracorporeal circulation or cardioplegic solution).
- Measurements included cardiac enzymes (CK, CK MB), free acid radicals, hemodynamics, arrhythmias, and histological examinations.
- Creatine phosphate use was associated with lower CK and CK MB levels and reduced ventricular dysrhythmias, especially in patients with pre-existing left ventricular systolic dysfunction.
Impact:
- Creatine phosphate may offer a protective effect against myocardial damage and arrhythmias in cardiac surgery patients.
- The findings suggest a potential benefit for creatine phosphate in managing patients with compromised systolic function.
- Further research is needed to confirm these cardioprotective effects and optimize its clinical application.
Abstract:
The authors submit their experience with the use of creatine phosphate in patients operated on account of coronary heart disease. They divided 50 consecutive patients into three groups. Group A--controls, group B--creatine phosphate was added to the filling of the apparatus for extracorporeal circulation and group C--creatine phosphate was added to Bretschneider's cardioplegic solution. During operation and during the early postoperative period the CK and CK MB levels were evaluated as well as levels of free acid radicals, the haemodynamic state of the patients, the incidence of ventricular dysrhythmias, the need of defibrillation, histological and histochemical examinations. The authors found a lower CK and CK MB level, a lower percentage of ventricular dysrhythmias and the same haemodynamic results of the operation in patients with a more markedly impaired systolic function of the left ventricle when creatine phosphate was used. Creatine phosphate did not affect the morphology of the heart muscle nor the level of the assessed myocardial enzymes.
