| Description | Aims. There are currently limited data about whether the effect of spironolactone in patients with resistant arterial hypertension depends on baseline blood pressure and the presence of a secondary cause of hypertension. Methods. Patients with office systolic blood pressure (BP) > 140 mmHg or diastolic BP > 90 mmHg, despite treatment with at least 3 antihypertensive drugs including a diuretic, were randomly assigned to receive spironolactone or a placebo for 8 weeks in a double-blind, placebo-controlled, multicentre trial (ASPIRANT). Results. Analyses were done with 55 patients treated with spironolactone. The degree of BP reduction after 8 weeks of spironolactone treatment did not differ significantly between the three tertiles of baseline systolic BP and patients with and without a secondary cause of hypertension. The reduction of office systolic, office diastolic BP and office pulse pressure was significantly lower in the highest tertile with baseline diastolic BP > 97 mmHg. Conclusions. Spironolactone treatment is effective to a similar extent both in patients with and without a secondary cause of hypertension and regardless of the baseline value of systolic BP. Less effect of spironolactone was found in patients with the highest baseline diastolic BP. |
