ABSTRACT
BACKGROUND: It's know that cardiopulmonary function affects the kidney perfusion and that erythropoietin (EPO) release depends on it. We want to determine the plasma level of EPO in the acute phase of myocardial infarction (AMI). SUBJECTS AND METHODS: A transversal trial was carried out in 37 male patients with AMI aged between 31 and 84. We studied the following variables: cardiovascular risk factors, time lapse from beginning of symptoms until hospital arrival, transcutaneous oxygen saturation (ST02) and EPO plasma levels. 16 healthy males were used as control group. RESULTS: Patients with AMI have different EPO levels than control group (25/37 vs 0/16) (18.90 +/- 8.43 mUI/ml vs 9.70 +/- 3.48 mUI/ml respectively p < 0.001). Hyperintense patients have higher EPO levels than normotense ones (18.53 +/- 8.28 mUI/ml vs 12.88 +/- 7.29 mUI/ml p < 0.05). Hypercholesterolemic patients have higher EPO level than normocholesterolemic ones (19 +/- 8.88 mUI/ml vs 12.40 +/- 6.75 mUI/ml p < 0.01). There were no difference between smokers and no smokers. We didn't find correlation between time lapse and EPO levels. CONCLUSION: The trial remarks EPO levels increase during the initial phase of AMI and it is higher in hypertensive and hypercholesterolemic patients.
