D-Dimer Levels and NIHSS Scores Predict Poor Outcomes in Elderly Stroke Patients: Study
Researchers have found in a new study that elevated D-dimer levels and higher NIHSS scores were found to strongly predict poor prognosis in elderly patients with cerebral infarction. Patients with worse outcomes had significantly higher D-dimer levels, which correlated positively with NIHSS scores. D-dimer showed 72% sensitivity and 74% specificity. Additional key risk factors included advanced age, atrial fibrillation, and a history of transient ischemic attacks. This study evaluates the relationship between D-dimer levels and NIHSS scores with prognosis in elderly patients with cerebral infarction.
Methods: This study was a retrospective study that included 112 elderly patients with cerebral infarction admitted to our hospital from January 2022 to December 2023. The modified Rankin Scale (mRS) was used to assess the prognosis at six-month follow-up, and patients were divided into two groups: good prognosis (mRS 0– 2) and poor prognosis (mRS 3– 6). Detailed data collection and statistical analysis were conducted, including descriptive statistics of baseline data, correlation analysis between D-dimer and NIHSS scores, and multivariate logistic regression analysis to identify independent risk factors for poor prognosis.
