In Reply We agree with Etyang’s assertion that the accurate assessment of blood pressure (BP) is an important step in determining cardiovascular risk and that efforts to improve the accuracy of BP measurement should be encouraged. This accuracy is equally important for screening, diagnosis, and ongoing management of patients because the consequences of inaccurate readings often lead to misdiagnosis and inappropriate treatment. However, Etyang also seems to imply that patients cannot be identified as having hypertension if they already have a diagnosis of hypertension. If correct, this belief would preclude a diagnosis of resistant hypertension, which currently describes many patients with high BP readings who are already receiving antihypertensive therapy.
