Hypertension may elevate SCD risk stratification; leaves open whether BP lowering reduces SCD in trials.
Is elevated blood pressure or hypertension associated with an increased risk of sudden cardiac death?
This meta-analysis demonstrates that prevalent hypertension and increasing systolic blood pressure are significantly associated with an increased risk of sudden cardiac death.
