ABSTRACT
A study on 48 patients with coronary artery diseases at Internal Medicine Department in Hue Central Hospital from July to December/1998. Results: Patients who live in urban: 62.5% and rural: 37.5%. The risk factors seen in study group is tobacco smoking (50%), hypertension (50%) and increased cholesterol level (40%). The average plasma fibrinogen level in 48 cases in control group is 11.07± 1.90µmol/l. A relative risk of fibrinogen plasma for coronary artery diseases is 3.18 (confidential interval (CI) 95%). Attribute risk is 0.65%, it means 65% case coronary artery diseases due to high plasma fibrinogen level. The incidence risk of coronary artery diseases increase 9.06 times in people with increase plasma fibrinogen level. So the routine test on plasma fibrinogen has value in prevention and predict coronary artery diseases.
