Implication
Observational analysis finds no link between isolated diastolic hypertension and cardiovascular events in adults, suggesting lower thresholds do not improve risk prediction.
Key Points
- To determine the prevalence of isolated diastolic hypertension under the 2017 ACC/AHA guideline compared to JNC7 criteria and evaluate its association with incident cardiovascular outcomes.
- Analyzed health data from US adults comparing isolated diastolic hypertension criteria from the 2017 ACC/AHA guideline against the JNC7 guideline.
- Evaluated the association between guideline-defined isolated diastolic hypertension and subsequent incident cardiovascular events.
- The estimated prevalence of isolated diastolic hypertension was substantially higher under the 2017 ACC/AHA guideline than under the JNC7 guideline.
- Isolated diastolic hypertension was not significantly associated with an increased risk of incident cardiovascular outcomes.
