# Effect of mean platelet volume and platelet count on the prognosis of branch atheromatous disease

## TL;DR

Higher mean platelet volume and platelet count are linked to worse outcomes in patients with branch atheromatous disease stroke.

## Contribution

This study identifies MPV and PC as independent predictors of poor prognosis in BAD-stroke patients.

## Key findings

- Elevated MPV and PC were independently associated with poor prognosis in BAD-stroke patients.
- MPV showed 74% sensitivity and 84.9% specificity in predicting poor outcomes.
- High MPV and PC were linked to early neurological deterioration, contributing to poor prognosis.

## Abstract

The purpose of this study was to investigate the predictive value of mean platelet volume (MPV) and platelet count (PC) in branch atheromatous disease (BAD).

This retrospective study included 216 patients with BAD‐stroke within 48 h of symptom onset. These patients were divided into good and poor prognosis groups according to their 3‐month modified Rankin scale scores after discharge. Multiple logistic regression analysis was used to evaluate independent predictors of poor prognosis in BAD‐stroke patients. Receiver‐operating characteristic (ROC) analysis was used to estimate the predictive value of MPV and PC on BAD‐stroke.

Our research showed that a higher MPV (aOR, 2.926; 95% CI, 2.040–4.196; p < .001) and PC (aOR, 1.013; 95% CI, 1.005–1.020; p = .001) were independently associated with poor prognosis after adjustment for confounders. The ROC analysis of MPV for predicting poor prognosis showed that the sensitivity and specificity were 74% and 84.9%, respectively, and that the AUC was .843 (95% CI, .776–.909, p < .001). The optimal cut‐off value was 12.35. The incidence of early neurological deterioration (END) was 24.5% (53 of 163), and 66% of patients in the poor prognosis group had END (33 of 50). Multiple logistic regression analyses showed that elevated MPV and PC were associated with the occurrence of END (p < .05).

Our results suggested that an elevated MPV and PC may be important in predicting a worse outcome in BAD‐stroke patients. Our study also demonstrated an independent association of MPV and PC with END, which is presumably the main reason for the poor prognosis.

BAD‐stroke patients with high MPV and PC are more likely to develop END and have poor prognosis at 3 months.
