What criteria is used to determine a diagnosis of hypertension?

The determination of a diagnosis of hypertension is primarily based on blood pressure readings that exceed set thresholds, specifically those identified by various health organizations. The correct criterion for diagnosing hypertension is defined as having a systolic blood pressure greater than 140 mm Hg and/or a diastolic blood pressure greater than 90 mm Hg. This definition is supported by guidelines from organizations such as the American Heart Association (AHA) and the American College of Cardiology (ACC), which classify hypertension into stages based on these readings.

The chosen threshold reflects a level at which the risk for cardiovascular disease and other complications significantly increases. Individuals with blood pressure consistently above these levels are at a greater risk and are therefore diagnosed with hypertension, which often necessitates lifestyle changes and possible medication to manage their condition.

Other options illustrate different thresholds that do not align with the recognized standards for diagnosing hypertension. For instance, readings of over 130/80 mm Hg and under 140/90 mm Hg represent elevated blood pressure or the earlier stages of hypertension, rather than a definitive diagnosis. Similarly, the other options suggest values that are either not aligned with or exceed the recognized clinical criteria for a diagnosis, highlighting the importance of using standardized measures in clinical practice.
