Home blood pressure tests could prevent heart attack and stroke

A study published in the European Heart Journal–Digital Health found that patients who self-monitored blood pressure with data shared to doctors had significantly lower risk of hospitalization and death compared to standard care, demonstrating a concrete positive health outcome.

This does not prove home monitoring alone causes the reduction—improved monitoring may correlate with better medication adherence, lifestyle changes, or closer physician attention rather than the monitoring itself being the causal factor.
