In middle-aged adults, aldosteronism is the most common secondary cause of hyperten-. sion, and the recommended initial diagnostic test is an aldosterone/. renin ratio. Up to 85 percent of children with hypertension have an. identifiable cause, most often renal parenchymal disease.
Kidney disease is the most common secondary cause of hypertension. Hypertension can also be caused by endocrine conditions, such as Cushing's syndrome, hyperthyroidism, hypothyroidism, acromegaly, Conn's syndrome or hyperaldosteronism, hyperparathyroidism and pheochromocytoma.ormal blood pressure at rest is within the range of 100â140 millimeters mercury (mmHg) systolic and 60â90 mmHg diastolic. Hypertension is present if the blood pressure is persistently at or above 140/90 mmHg for most adults; different numbers apply to children.
