Abstract:
Objective To investigate the relationship between plasma fibrinogen levels,aldosterion levels and left ventricular mass in patients with essential hypertension.Methods Two hundred and seventy-three patients with essential hypertension were selected as subjects.Eldow vonous blood sample were taken to measure the rennin,aldosterion,fibrinogen,D-dimer,prothrombin fragment 1 + 2 (F1 + 2),and plasminogen activator inhibitor-1 (PAI-1) concentration by radioimmunoassay.And assessed cardiac structure and function in patients ultrasound heartbeat by application of ultrasound heartbeat.According to fibrinogen levels,all patients were divided to low(A group,n =95),medium (B group,n =87) and highest (C group,n =91) groups,and comparative analyzed the general clinical data,biochemical indexes,ultrasound heartbeat graph test results of the 3 groups.Meanwhile to compare the differences between 3 groups of left ventricular mass index on the two different concentrations of plasma aldosterone average ≥ 125 pmol/L or ＜ 125 pmol/L.Results Left ventricular mass index (LVMI) increased in patients with aldosterone levels ≥ 125 pmol/L as the plasma aldosterone increased significantly.The left ventricular mass index in A,B,C group were (35.0 ± 3.1),(45.0 ± 3.6),(51.0 ± 2.9) g/m2 respectively,the difference between the 3 groups have statistical significance (F =6.65,P ＜ 0.01).Within C group,LVMI in patients with aldosterone concentration(≥ 125 pmol/L) was greater than ＜ 125 pmol/L(t =11.65,P ＜ 0.01).Meanwhile the fibrinogen concentration gradually increased in A,B and C group (2630 (2420-2790),3290 (3170-3430),4210 (3791-4580),respectively).Fibrinogen concentration in C group was higher than that in the other two groups (Z =-2.46,P ＜ 0.01).Ultrasonic heartbeat graph examination Results showed that left ventricular diameter in C group was the biggest than that in A and B groups (A,B,C group were (20.0 ± 2.3),(22.0 ± 3.9),(23.0 ± 3.1) mm/m2 respectively,F =8.16,P ＜ 0.05);The same trends were also seen regarding of interventricular septal thickness (A,B,C group were(9.2 ± 1.9),(10.1 ± 2.0),(10.5 ± 2.4) mm respectively,F =10.52,P ＜ 0.01),left ventricular posterior wall thickness (A,B,C group were (8.8 ± 1.5),(9.2 ± 1.6),(9.7 ± 1.7) mm respectively,F =10.6,P＜0.01) and left ventricular mass(A,B,C group were(37 ±9),(43 ± 11),(45 ± 13) g/m2 respectively,F =11.6,P ＜ 0.01).Conclusion Plasma fibrinogen and aldosterone concentrations are associated with left ventricular mass in patients with essential hypertension.Both them of interaction and participate to left ventricular hypertrophy commonly.
