[Correspondence] Should the cutoff for hypertension in older adults be different from younger adults?

The American College of Cardiology and American Heart Association has modified the definition of hypertension in adults.1 In this definition, blood pressure is divided into four groups, including normal blood pressure, elevated blood pressure, stage 1 hypertension, and stage 2 hypertension. These cutoffs were chosen on the basis of the relationship between systolic blood pressure (SBP) and diastolic blood pressure (DBP) with the incidence of cardiovascular diseases.1
