3 Resistant Hypertension Hypertension is usually defined resistant or refractory to treatment when a therapeutic plan that has included attention to lifestyle measures and the prescription of at least three drugs (including a diuretic) in adequate doses has failed to lower systolic and diastolic blood pressure to goal. According to this definition prevalence of resistant hypertension is relatively high (in ALLHAT 8% pts with 4 drugs and 15% with resistant hypertension). In such situations, referral to a specialist or a hypertension center should be considered, because resistant hypertension is recognized to be often associated with subclinical organ damage and a high or very high cardiovascular risk ESH/ESC Hypertension Guidelines Mancia G, et al.

4 Epidemiologia dell‘Ipertensione Arteriosa in Italia

5 Schematic Representation of the Catheter Ablation of Renal Arteries

6 The Renal Denervation Procedure 4-6 focal treatments are delivered – 120 seconds per treatment – ≥5 mm between locations – Stable, unique locations – Circumferential coverage The catheter is pulled, rotated, and new location and prior treatment site are assessed

28 Take-Home Message Il trattamento dell’ipertensione arteriosa non controllata (o resistente) richiede l’impiego di terapie di combinazione con diverse classi di farmaci. Tali terapie di combinazione dovrebbero essere: – Semplici – Razionali – A dosaggio “adeguato” (pieno) Studi clinici disponibili dimostrano come l’impiego di terapie di combinazione duplici o triplici (farmaco bloccante RAS, diuretico tiazidico e CCB diidropiridinico a dosaggio pieno) consentono di ottenere il controllo dei valori di PAS/PAD in oltre 70-80% dei pazienti trattati. Nel rimanente 20-30% l’impiego di farmaci di 4 scelta (antialdosteronici o inibitori diretti della renina) può consentire di ridurre ulteriormente i valori pressori e raggiungere il controllo dei valori pressori. Nei casi non responsivi alla terapia (o con documentate allergie o intolleranze), l’impiego della denervazione delle arterie renali rappresenta una opzione efficace, sicura e ben tollerata per ridurre i valori pressori e contribuire a raggiungere il controllo della pressione arteriosa.
