RESUMO
Adherence to antihypertensive medication is an important challenge that doctors often face in the treatment of hypertension. Good adherence is crucial to prevent cardiovascular complications. In consequence, the present study aimed at determining the prevalence of adherence to antihypertensive treatment and identifying associated clinical variables. A multicenter cross-sectional study was conducted in 12 cities of Argentina. A systematic sampling was performed in order to select patients with hypertension and under pharmacological treatment for at least 6 months. Physicians took three BP measurements, and the level of adherence was assessed using the self-administered Morisky questionnaire (MMAS-8). Participants were classified into three levels of adherence: high adherence-MMAS score of 8; medium adherence-MMAS scores of 6 to <8; and low adherence-MMAS scores of <6. A total of 1111 individuals (62 ± 12 years old, women 49.4%) were included in the present analysis; 159 (14.3%), 329 (29.6%) and 623 (56.1%) patients had low, medium, and high adherence, respectively. The prevalence of controlled hypertension increased only in high adherent patients: 42.8%, 42.2%, and 64.5% for low, medium, and high adherence groups, respectively. Similarly, systolic BP was lower only in the high adherence group. High educational level (OR 3.47, 95% CI 2.68-4.49) and diuretic treatment (OR 0.64, 95% CI 0.47-0.88) were independent predictors of high adherence. In conclusion, more than a half of treated hypertensive patients had a high level of adherence. These patients had lower BP values and higher control levels. A high educational level predicts high adherence.

En la Argentina no existen datos epidemiológicos sobre displasia fibromuscular. La realización de un registro nacional puede aportar información que conduzca a una actualización de los consensos y recomendaciones para un correcto diagnóstico, evaluación y tratamiento. El Registro Argentino de Displasia Fibromuscular (SAHARA-DF) inició su actividad de recopilación de datos en octubre de 2015. Al año 2019 se confirmaron 49 pacientes (44 mujeres, 38 hipertensos, edad 45,3 ± 17,2 años, 12 con presentación neurológica). Veintidós pacientes tuvieron lesiones vasculares en más de un sitio, a pesar del sesgo diagnóstico por falta de estudios complementarios en casi la mitad de los casos. El sitio afectado más frecuente fue el renovascular, seguido por el carotídeo y el ilíaco, y las lesiones multifocales fueron más frecuentes que las unifocales (35 versus 14, respectivamente). Se constató la presencia de aneurismas asociados en 13 casos y disección arterial en 4 casos. De las 22 angioplastias renales realizadas, 14 fueron con colocación de stent (endoprótesis). En este estudio preliminar de una población argentina se evidencia el carácter sistémico de la enfermedad y se plantea un llamado a actuar en cuanto a la necesidad de debatir el algoritmo diagnóstico y el método de tratamiento.

In Argentina there are no epidemiological data regarding fibromuscular dysplasia. Building a National Registry may provide information leading to updated consensus and recommendations for a correct diagnosis, assessment and treatment. Data gathering for the Argentine Registry of Fibromuscular Dysplasia (SAHARA-DF) was initiated in October 2015. By 2019, 49 patients were confirmed (44 women, 38 hypertensives, age 45.3 ± 17.2 years, 12 with a neurological presentation). Twenty-two patients had multi-site vascular lesions, in spite of a diagnosis bias due to lack of supporting studies in almost half of the cases. The renovascular site was the most affected, followed by the carotid and iliac sites, and multifocal lesions were more frequent than unifocal (35 versus 14, respectively). Associated aneurysms were found in 13 cases, and arterial dissection in 4. Twenty-two renal angioplasties were performed, 14 with stent placement. In this preliminary study of an Argentinian population, the systemic nature of the disease is evidenced, and a call for action arises regarding the need for discussing the diagnostic algorithm and treatment method.
