[HYPERTENSION IN A PATIENT WITH AN ADEQUATELY TREATED COARCTATION OF THE AORTA - WHAT IS THE REASON FOR UNCONTROLLED HYPERTENSION?]

INTRODUCTION A 35 year old patient, who had a successful surgical repair of coarctation of the aorta in early childhood, was referred for investigation regarding the cause for resistant hypertension. He underwent a full workup which was negative. Due to elevated renin levels his medications were altered with corresponding normalization of the renin levels. Symptomatic palpitations subsided after stopping treatment with a calcium channel blocker (lercanidipine), which implies reflex tachycardia secondary to lercanidipine. After all the investigations and interventions were performed, it appears that the etiology of resistant hypertension in his case is secondary to the coarctation, in spite of prior successful therapeutic interventions.
