[Physician knowledge and attitudes on the clinical evaluation and treatment of resistant hypertension: The RESIST study].
Hipertensión y Riesgo Vascular 2017 January
BACKGROUND: Resistant hypertension (RH) is associated with a high risk of cardiovascular and renal complications. The purpose of this study was to assess the knowledge and attitudes of Primary Care physicians, general medicine doctors, and clinical cardiologists on the management of this condition.
MATERIAL AND METHODS: A multicentre, descriptive, observational study based on an ad hoc questionnaire distributed to Primary Care physicians (n=1017) and general medicine physicians/clinical cardiologists (n=457).
RESULTS: To establish the diagnosis of resistant hypertension, 69.1% of physicians confirm that systolic/diastolic blood pressure is above 140/90 mmHg, despite treatment. Furthermore, 64.9% only consider this diagnosis if the patient is treated with at least 3 medications, and 50.3% also requires that one of them is a thiazide diuretic (56.7% among specialists, P=.0004). To establish a definite diagnosis of true RH, 89.6% perform 24-h ambulatory blood pressure monitoring (93.3% of specialists, P=.0017), looking specifically for «white-coat» effect in 70.2% of cases. In addition, 79.3% verify that adherence to treatment is adequate. Between 87 and 95% of physicians indicate examinations to exclude causes of secondary hypertension. Up to 54.3% of physicians (71.3% specialists, P<.0001) consider adding a fourth drug and insisting on lifestyle interventions as a priority therapeutic measure.
CONCLUSION: These data show that physician knowledge regarding the management of patients with RH is good. Interestingly, this knowledge is somewhat higher among specialists than among Primary Care physicians.
