The study aimed to assess the association between H-type hypertension and clinical prognosis in patients with LVO after receiving EVT.Methods: Our study enrolled patients from the Endovascular Treatment With versus Without Tirofiban for Stroke Patients with Large Vessel Occlusion (RESCUE BT) Trial. H-type hypertension is defined as patients with hypertension and homocysteine (Hcy) ≥ 10μmol/L. The primary outcome was a favorable functional outcome, defined as a score of 0– 2 on the modified Rankin Scale (mRS) at 90 days. The secondary outcomes were mortality, successful recanalization, futile recanalization, and symptomatic intracerebral hemorrhage (sICH).Results: The plasma homocysteine level was recorded for 215 patients with hypertension in our study. Among those patients, 172 patients (80%) were founded with Hcy ≥ 10μmol/L (H-type hypertension), and 43 patients (20%) with Hcy < 10μmol/L (non-H-type hypertension). The probability of favorable outcome decreased with homocysteine increasing in patients with hypertension. H-type hypertension was associated with a low probability of favorable outcome (adjusted odds ratio (aOR), 0.38 [95% confidence interval (CI), 0.18– 0.80]; p = 0.01) at 90 days. The effects of H-type hypertension on mortality (aOR, 1.90 [95% CI, 0.67– 5.39]; p = 0.23) and sICH (aOR, 0.55 [95% CI, 0.13– 2.29]; p = 0.41) were not significant.Conclusion: Our findings suggest that patients with H-type hypertension have a lower likelihood of achieving favorable outcomes but do not have an increased mortality rate within 90 days.Keywords: H-type hypertension, clinical prognoses, large vessel occlusion
