Objective:
To investigate the relationship between cerebral microbleeds (CMB), cardiovascular risk factors, and plasma fibrinogen in patients with acute ischemic stroke.
Methods:
Sixty-eight patients with acute ischemic stroke from June 2008 to March 2009 were enroued prospectively. All patients received cranial magnetic resonance imaging at the first week, and T2(*)-weighted gradient echo MRI sequence was performed to detect CMB. Plasma fibrinogen, uric acid levels and other biochemical parameters were measured on the next day of admission. All data were selected from Nanjing Stroke Registry Program.
Results:
Among a total 68 patients, 29 (43%) patients had 109 lesions of cerebral microbleeds on gradient-echo MRI. Age, hypertension, fibrinogen and uric acid were significantly associated with the presence of CMB (P = 0.004, 0.024, 0.020, 0.027 respectively). Through a logistic regression analysis, age, hypertension and plasma fibrinogen were significantly associated with the presence of cerebral microbleeds [(P = 0.02, OR = 1.10, 95%CI 1.02 to 1.19; P = 0.003, OR = 9.35, 95%CI 2.17 to 40.23; P = 0.019, OR = 1.01, 95%CI 1.00 to 1.02].
Conclusion:
There is a high prevalence of CMB in patients with acute ischemic stroke. And it has a strong relationship with high plasma fibrinogen.
Insights
Cerebral microbleeds (CMB) are common in acute ischemic stroke patients. High plasma fibrinogen levels are strongly associated with the presence of CMB, indicating a significant relationship.
Area of Science:
- Neurology
- Vascular Medicine
- Biochemistry
Context:
- Acute ischemic stroke presents a significant health challenge.
- Cerebral microbleeds (CMB) are increasingly recognized as a marker of cerebrovascular disease.
- Understanding factors associated with CMB is crucial for stroke management.
Purpose:
- To investigate the association between cerebral microbleeds (CMB) and cardiovascular risk factors, specifically plasma fibrinogen levels, in patients experiencing acute ischemic stroke.
Summary:
- A prospective study of 68 acute ischemic stroke patients found that 43% had cerebral microbleeds (CMB) detected via MRI.
- Significant associations were observed between CMB presence and age, hypertension, plasma fibrinogen, and uric acid levels.
- Logistic regression analysis confirmed age, hypertension, and plasma fibrinogen as independent predictors of CMB.
Impact:
- This study highlights the high prevalence of CMB in acute ischemic stroke.
- Findings underscore the critical link between elevated plasma fibrinogen and cerebral microbleeds, suggesting potential therapeutic targets.
