Isolated systolic hypertension is defined as a systolic pressure greater than what value with a diastolic pressure under 80?

Isolated systolic hypertension is characterized by a systolic blood pressure that is elevated, specifically greater than 130 mmHg, while the diastolic blood pressure remains under 80 mmHg. This condition is particularly relevant in older adults, where the systolic pressure can rise due to stiffening of the arteries, yet the diastolic pressure may remain stable or low. Recognizing this definition is crucial for diagnosing and managing hypertension, as it can help prevent cardiovascular complications that may arise from untreated elevated systolic pressures. Understanding these classifications aids healthcare providers in assessing cardiovascular risk and determining appropriate interventions for patients.
