Crystalloid versus blood cardioplegia in myocardial preservation during cardiopulmonary bypass

ABSTRACT

Sixty patients with an age group ranging between 15 and 54 years [mean 40 +/- 4], 26 males and 34 females, arranged in three groups according to the type of cardioplegia used during different types of cardiac surgical procedures performed. The postoperative assessment of myocardial preservation was depended on the hemodynamic affection, laboratory measurement of CPK and LDH and follow up echocardiography. The results showed more efficacy of cold crystalloid cardioplegia and continuous warm cardioplegia to preserve the myocardium in the period of ischemic arrest than cold crystalloid cardioplegia, especially in patients with borderline left ventricular function
