BACKGROUND: Many known risk factors, including hypertension and hyperlipidemia cause intracerebral hemorrhage (ICH). Recently, microbleeds have been identified as one of the factors leading to ICH. While some patients have been found to have recurrent ICH, risk factors for recurrent ICH are scarcely reported. We conducted an observational study on the risk-factors of recurrent ICH, comparing stroke patients with a single hemorrhagic episode and those with recurrent ICH.
METHODS: A retrospective analysis of a single-center database was performed to analyze the clinical presentation and characteristics of patients with a single and recurrent ICH. From January 2016 to December 2017, a total of 317 patients were analyzed based on suspected factors including patients' sex, age, medical history, antiplatelet therapy use, and presence of microbleeds on images.
RESULTS: Of the 317 patients, 36 patients (11.4%) developed a second episode of cerebral hemorrhage. Brain magnetic resonance imaging (MRI) of the patients without microbleeds, predicted reduced risk of recurrence. This is the first report strongly associating the presence of microbleeds with the possibility of a recurrent ICH. Other factors under study did not show an apparent association with recurrent ICH probably because of the high statistical significance obtained with the presence of microbleeds.
CONCLUSION: Our findings revealed that the absence of microbleeds on images is a factor that strongly predicts a reduced risk for recurrent ICH and that the detection of microbleeds on MRI performed in patients with a single hemorrhagic episode, is useful in defining further therapeutic management. These findings may benefit physicians treating stroke patients.
