Measurement of Plasma Fibrinogen and D-dimer Levels in Sudanese Hypertensive Patients at Khartoum state

Background: Hypertension is a chronic elevation of blood pressure that, in the long-term, causes end organ damage and results in increased morbidity and mortality. Thrombosis often appears to complicate the course of patients with hypertension; thrombosis in some patients with hypertension could be developed to organ damage. The aim of this study was to measure fibrinogen and D-dimer level among sudanese patients with hypertension. Materials and method: This was a case control study conducted at Khartoum state, Sudan during the period from May 2022 to August 2022 to measure fibrinogen and D-dimer levels in sudanese patients with hypertension. Blood samples were collected, 50 from the patients as case group, and 50 from normal healthy subjects as control group. A total of three ml of whole blood were collected from each participant in sodium citrated tube. The fibrinogen and D-dimer level measurement was done by using coagulometer (M1 coatron) and ichroma II device respectively. Results: The results of this study revealed that when compared Fibrinogen level and D-dimer between cases and control group; the results revealed that fibrinogen level was significant increase in hypertensive patients with P-value of 0.000. Also, D-dimer was significant increase in hypertensive patients when compared with the results of control group, and showed significant association with P-value of 0.000. There was a negative correlation between hypertension and the gender, but the age showed positive correlation with hypertension and with D-dimer, where both fibrinogen and D-dimer showed positive correlation with the duration of hypertension. Conclusion: This study concluded; when compared the fibrinogen level and D- dimer between cases and control group, there was significant increase in fibrinogen and D- dimer.
