Abstract:
ObjectiveToinvestigatetherelationshipbetweenserumcystatinC(CysC)leveland hypertensive intracerebral hemorrhage (HICH). Methods The patients w ith HICH and healthy controls w ere enroled. The demographic and clinical data were colected. Immunoturbidimetric assay was used to detect serum CysC level. Results A total of 94 consecutive patients w ith HICH and 131 healthy controls w ere enroled. The baseline systolic blood pressure ( 168.57 ±28.64 mmHg vs.128.13 ±16.23 mmHg; t=-13.442, P<0.001;1 mmHg=0.133 kPa), diastolic blood pressure ( 95.56 ±14.68 mmHg vs.76.80 ± 8.76 mmHg; t= -11.965, P<0.001 ), fasting plasma glucose ( 6.24 ±1.83 mmol/L vs.5.22 ± 1.13 mmol/L; t= -4.234, P<0.001), and serum CysC level (1.02 ±0.26 mg/L vs.0.91 ±0.13 mg/L, P<0.001) in the HICH group w ere significantly higher than those in the control group. Multivariable logistic regression analysis show ed that baseline systolic blood pressure≥140 mmHg ( odds ratio [ OR] 12.523, 95% confidence interval [CI] 5.353-29.299; P<0.01), diastolic blood pressure ≥90 mmHg (OR 3.968, 95%CI 1.792-8.784; P<0.01 ) and serum CysC level≥1.09 mg/L ( OR 3.279, 95%CI 1.336-8.050; P<0.05) w ere the independent risk factors for HICH. In patients w ith HICH, the CysC serum level (1.13 ±0.26 mg/L) in the bleeding ≥30 ml group w as higher than that in the bleeding <30 ml group (0.99 ±0.25 mg/L; P<0.001) and the control group ( 0.91 ±0.13 mg/L; P<0.001). The serum CysC level in the bleeding volume <30 ml w as higher than that in the control group ( P=0.004). There w ere positive correlations betw een serum CysC and age, creatinine, urea, and uric acid (al P<0.01);there w ere negative correlations betw een serum CysC level and the estimated glomerular filtration rate ( P<0.01). Multivariable linear regression analysis show ed that age, creatinine, urea and uric acid w ere independent associated w ith the serum CysC level ( al P<0.05 ). Conclusions The increased serum CysC level is correlated w ith the amount of bleeding in patients w ith HICH. The increased serum CysC level is an independent risk factor for HICH.
