Laboratory, electrocardiographic and clinical changes in individuals subjected to intense stress



Laboratory, electrocardiographic and clinical changes in individuals subjected to intense stress



Arquivos Brasileiros de Cardiologia 34(2): 87-96



Individuals (3) were used to study stress as a combination of organic reactions due to physical, psychic or any other aggressions capable of disturbing homeostasis. The first 2 individuals (A and B) participated in a national motor cycle race competition, alternating every 90 min., for 24 h. Individual C did not participate and acted as control. They were evaluated in 3 different situations: before (I), during (II) and after (III) the race. During period II, examinations were performed every 3 h by collecting material from competitors A and B when alternating and from individual C. Temperature, pulse, blood pressure, ECG, erytrocyte sedimentation rate, complete blood cell count and levels of serum Ca, P, lipids, glucose, blood urea N, uric acid, protein bilirubin, alkaline phosphatase, high density lipoprotein, aspartate transaminase, creatine phosphokinase, glutamic pyruvate transaminase and .alpha.-hydroxybutyrate dehydrogenase were considered. Results during the race showed important increases and peculiar behavior of enzyme levels; the influence of stress on enzymatic levels in cases of proven tissue injuries is discussed.
