Abstract
Background: Intracerebral hemorrhage (ICH) has high mortality and morbidity rates in the world. Homocysteine (Hcy) has been demonstrated to be an independent risk factor and could predict the prognosis and recurrence of ischemic stroke. In our study, we aimed to find out the relationship between Hcy levels and the severity and prognosis of patients with ICH.Methods: Patients' basic characteristics and laboratory examination results, including the concentration of homocysteine, were taken at baseline from January 2014 to September 2016, and a 1 year follow-up, including the modified Rankin Scale and living status, was taken for all the patients. Logistic regression and Kaplan–Meier survival method were used to analyze the relationship between different Hcy levels and clinical outcome.Results: A total of 551 patients with acute ICH from 13 hospitals in Beijing were enrolled in our study. High Hcy was detected in 284 patients (51.5%). Percentage of male, smoking, drinking, and concentration of hemoglobin A1c and triglyceride levels showed a significant difference between different Hcy level groups (all P-values <0.05). In the logistic regression analysis, high Hcy level is an independent risk factor for the prevalence of 3 month poor prognosis [odd ratio (95% confidence interval) = 1.601 (1.063–2.412), P = 0.0242], especially in female subgroup. In the 1 year follow-up period, high Hcy level patients had a significantly higher rate of fatal incidence compared to normal Hcy level patients (P = 0.0023).Conclusions: High Hcy level was independently associated with poorer 3 month prognosis and a lower survival rate within 1 year in patients with ICH.
Highlights
Acute spontaneous intracerebral hemorrhage (ICH) is one of the most common critical diseases in the neurological field
The present study showed high Hcy level to be independently associated with poorer 3 month prognosis and a lower survival rate within 1 year in patients with ICH
These results suggest the possibility that in patients with acute ICH, high Hcy concentration plays a role in the development of and recovery after ICH onset
Summary
Acute spontaneous intracerebral hemorrhage (ICH) is one of the most common critical diseases in the neurological field. The Global Burden of Disease Study 2016 and Stroke in China section reported that ICH has a higher mortality rate than ischemic stroke in the world and higher morbidity rate in China than other high-income countries [1,2,3]. Previous studies have demonstrated that elevated total homocysteine level is an independent risk factor of ischemic stroke, and high Hcy levels predicted poorer prognosis and higher recurrence [6,7,8]. Intracerebral hemorrhage (ICH) has high mortality and morbidity rates in the world. Homocysteine (Hcy) has been demonstrated to be an independent risk factor and could predict the prognosis and recurrence of ischemic stroke.
