Hyperaldosteronism: recent concepts, diagnosis, and management.

چکیده
As a cause for hypertension, aldosterone excess is now thought to be more prevalent than previously quoted in textbooks. Classical features of hypokalaemia and metabolic alkalosis can be absent even in the presence of marked hypertension. This implies the need for a high index of suspicion and possibly argues the case for routine screening, especially in patients with “diYcult to treat” hypertension. Given multisystem target organ damage and increased cardiovascular risk associated with chronic uncontrolled hypertension, a readily treatable cause such as hyperaldosteronism is an important diagnosis to make. In addition, hyperaldosteronism related hypertension is now known to cover other recently identified monogenic disorders such as glucocorticoid remediable aldosteronism. These rarer monogenic hypertensive disorders provide clues to cracking the mystery behind polygenic “essential” hypertension. Apart from patients with hyperaldosteronism, a subset of the well recognised “low renin hypertension” patient group also appears to produce a dramatic and remarkable response when treated with spironolactone. We suggest that spironolactone sensitive hypertension may represent a wider spectrum of disorders where blood pressure is readily controlled by the addition of aldosterone receptor antagonist.

Primary hyperaldosteronism is one of the few causes of hypertension that can be cured by surgery. Primary hyperaldosteronism is caused by adrenocortical adenoma or hyperplasia. It is important to differentiate between adrenal adenoma and hyperplasia because the preferred treatments are different. In all patients with new-onest or worsening hypertension the primary hyperaldosteronism should be c...

Primary aldosteronism affects 5-13% of patients with hypertension. Patients with hypertension and hypokalemia and most patients with treatment-resistant hypertension should undergo screening for primary aldosteronism with a plasma aldosterone concentration to plasma renin activity ratio. A high plasma aldosterone concentration to plasma renin activity ratio is a positive screening test result, ...

Primary aldosteronism is the commonest form of hormone-related hypertension, with an estimated prevalence of 6-13% in the generalpopulation of hypertensive patients. Among patients with resistant hypertension, the proportion of PA is even higher. Through intensiveresearch in the field of basic science and the creation of large registries of patients with PA, it is possible to understand the eff...
