The objectives were to identify risk factors for vein thromboembolic diseas
e (VTD) among patients with acute myocardial infarction (AMI) and to analys
e both quantitatively and qualitatively the performed thromboembolic prophy
laxis, A cross-sectional study was carried out with all inpatients at the C
oronary Unit at our hospital during 1998. The risk factors for thromboembol
ism included: inmobilization (79,2%), heart failure (33,2%) and age over 70
years (31%). VTD prophylaxis was performed in 86,9% of the time, Non-fract
ioned heparin (NFH) and low molecular weight heparins (LMWH), mostly nadrop
arine, were the most commonly used drugs at admission and at discharge, res
pectively. Overdosage and underdosage for NFH and LMWH, respectively, were
observed. That patients received or not VTD prophylaxis was not influenced
by thromboembolic risk factors.
