• Resistant hypertension(RH) has been defined as failure to control office blood pressure (BP) despite the use of≥3 different antihypertensive agents at optimal doses, including, ideally, a diuretic. Apparent RH, defines patients with an incorrect diagnosis of RH due to different causes. The objective was to determine whether most patients with RH in fact have apparent but not true RH. Observational study involving 93 patients with suspected RH, being 60 patients finally included. Screening for secondary causes of hypertension was perfomed. True RH was defined as office BP>140/90mmHg despite full doses of 3 antihypertensive drugs including a diuretic. Mean age 63.7±9.8years, 68.3%were male. Office BP 154.3±14.4/84.4±13.7mmHg. Of the 60 patients, 23.3% had white coat effect, 3.3% didn't have a diuretic and 8.3% were non-adherent-to-treatment. Accordingly, 58.3% were classified as true RH. Spironolactone was added in 62.5% of patients of whom 78.4% achieved ambulatory BP control. Almost half of the patients with suspected RH were not really true RH. We provide more evidence of excess of fluid retention as an underlying cause of lack of BP control in patients with RH, reinforce the relevant paper of spironolactone for the management in those patients.
