Assessment of hypertension also includes its effects on target organs—the eyes, the heart, the brain, and the kidneys. Look for evidence of hypertensive retinopathy, left ventricular hypertrophy, and neurologic deficits suggesting a stroke. (Renal assessment requires urinalysis and blood tests.)
*When the systolic and diastolic levels indicate different categories, use the higher category. For example, 170/92 mm Hg is moderate hypertension and 170/120 mm Hg is severe hypertension.
In isolated systolic hypertension, systolic pressure is 140 mm Hg or more and diastolic pressure is less than 90 mm Hg.
Relatively low levels of blood pressure should always be interpreted in the light of past readings and the patient's present clinical state.
