Descrição: Hypertension is a very common modifiable risk factor for cardiovascular morbidity and mortality. Patients with hypertension represent a diverse group. In addition to those with primary hypertension, there are patients whose hypertension is attributable to secondary causes, those with resistant hypertension, and patients who present with a hypertensive crisis. Secondary causes of hypertension account for less than 10% of cases of elevated blood pressure (BP), and screening for these causes is warranted if clinically indicated. Patients with resistant hypertension, whose BP remains uncontrolled in spite of use of 3 or more antihypertensive agents, are at increased cardiovascular risk compared with the general hypertensive population. After potentially correctible causes of uncontrolled BP (pseudoresistance, secondary causes, and intake of interfering substances) are eliminated, patients with true resistant hypertension are managed by encouraging therapeutic lifestyle changes and optimizing the antihypertensive regimen, whereby the clinician ensures that the medications are prescribed at optimal doses using drugs with complementary mechanisms of action, while adding an appropriate diuretic if there are no contraindications. Mineralocorticoid receptor antagonists are formidable add-on agents to the antihypertensive regimen, usually as a fourth drug, and are effective in reducing BP even in patients without biochemical evidence of aldosterone excess. In the setting of a hypertensive crisis, the BP has to be reduced within hours in the case of a hypertensive emergency (elevated BP with evidence of target organ damage) using parenteral agents, and within a few days if there is hypertensive urgency, using oral antihypertensive agents.
