Abstract

To study the relationship between the hormone response to stress seen after ACV (CVA) and the type, size and site of the lesion. We made a prospective study of the relationship between stress hormones and the radiological characteristics of the lesion in 82 patients admitted to hospital for non AIT ACV (CVA). We assessed the 24 hour urine catecholamines (total catecholamines, adrenaline, noradrenaline, vanillylmandelic acid, metanephrines and dopamine) and the 24 hour urine cortisol, collected on the second and third day after admission respectively. The type, size and site of the lesions were studies on CT scans done between 3 and 7 days after admission. We studied 82 patients, 43 men and 39 women with an average age of 71.7. In 7 patients the lesion was parenchymatous haemorrhage; in 75 it was an infarct, which was small (< 6 cm3) in 30.5%, moderate sized (6-60 cm3) in 38.6% and large in 30.6%. In the cases of infarct, only the cortisol was significantly different in the three groups (average (DE) standard deviation, respectively: 80.6 (50), 114 (124) and 246 (207); p = 0.0014). This relationship persisted when the cortisol level was compared with the volume in cm3 (p = 0.0028). The cortical infarcts had significantly higher ...Continue Reading
