ABSTRACT
Hypertension is an established risk factor for acute coronary events. Growing evidence is now apparent that hypertension is accompanied by hypercoagulable and/or hypofibrinoltic state, both of which can be the cause of several cardiovascular risk factors noticed with hypertension. To show the relationship between hypertension and some components of fibrinolytic and coaguIation systems . In this study, the plasma levels of fibrinogen, FVII, D-dimer, t-PA and PAI-I were studied in three groups of male persons. A hypertensive group of patients [16], complicated hypertensive group [16] and a group of normotensive persons [16] were included in this work Patients were selected from outpatient clinic of Cardiology Department, Assiut University Hospital, during the period from December 2001 until December 2002. The mean plasma levels of fibrinogen, FFVII, t-PA, PAZ-I and D dimer before treatment of the hypertensive and complicated hypertensive groups were significantly higher than that of the normotensive group .The mean plasma levels of these factors [except FVII] in the complicated hypertensive group were significantly higher than that of the hypertensive group. After treatment of these groups, the mean plasma levels of all factors decreased significant and there was no significant difference between the two groups. It is clear from this study that there are disturbances in the levels of coagulation and fibrinolytic factors in hypertensive patients particularly in the complicated hypertensive patients. This indicates severity of disturbance of these factors in hypertensive patients making them risk factors for the development of coronary heart disease, myocardial infarction, unstable angina, etc
