The significance of determination of the fraction of creatinine-phosphokinase in patients with acute ischemic brain disease.

: Heart and brain vascular diseases are the leading causes of mortality in the world. Cardiac complications can frequently occur during the development of cerebral ischemia. The aim of this study was to establish the possible changes in fractions of creatinine-phosphokinase as the sensitive laboratory index of parenchymal lesion of brain parenchyma and the presence/absence of risk factors for ischemic brain and heart disease. The study comprised 80 patients with acute ischemic brain disease (AIBD), without the history of previous coronary disease. Blood samples were taken in all patients within the first 48 hours from AIBD onset aiming to determine a total (muscular MM) and heart fraction of creatinine-phosphokinase (MB), and brain parenchyma ischemia was confirmed by CT or MR scan of the head. A detailed history of the risk factors for ischemic brain disease (IBD) and ischemic heart disease was taken from all patients with AIBD, and the profile of glycemia and lipid status were determined, and blood pressure was measured 6 times a day. Independent variables in statistical analysis were: age, degree of severity and the side of neurologic event, size of ischemic lesion and maximal values of systolic and dyastolic pressure. Dependent variables were the values of fractions of creatinine-phosphokinase (CPK). Control group (n = 40) comprised patients with neurologic diseases of non-vascular origin. All parameters as well as their interrelations were statistically analyzed. The results revealed significant correlation of the increased levels of CPK of MM and MB fraction with the size and place of ischemic lesion in the right cerebral hemisphere, which was highly significant for MB fraction in the total group of patients with AIBD, and for MM fraction, only for cases of more severe IBD. Highly significant increased values of those fractions were also observed compared to the control group of patients.
