Renal denervation remains investigational for resistant hypertension; review extends mechanistic context but leaves clinical adoption open.
There is a marked contrast between the high prevalence of hypertension and the low rates of adequate control. A subset of patients with suboptimal blood pressure control have drug-resistant hypertension, in the pathophysiology of which chronic sympathetic hyperactivation is significantly involved. Sympathetic renal denervation has recently emerged as a device-based treatment for resistant hypertension. In this review, the pathophysiological mechanisms linking the sympathetic nervous system and cardiovascular disease are reviewed, focusing on resistant hypertension and the role of sympathetic renal denervation. An update on experimental and clinical results is provided, along with potential future indications for this device-based technique in other cardiovascular diseases. A elevada prevalência da hipertensão está em claro contraste com a sua ainda insuficiente taxa de controlo. Um importante subgrupo destes doentes apresenta uma hipertensão resistente aos fármacos, na qual a hiperativação crónica do sistema nervoso simpático tem importantes implicações fisiopatológicas. Recentemente, a desnervação simpática renal emergiu como um tratamento de intervenção para a hipertensão arterial resistente. No presente artigo, são revistos os mecanismos fisiopatológicos subjacentes à interação entre o sistema nervoso simpático e as doenças cardiovasculares, com particular enfâse na hipertensão arterial resistente e no papel da desnervação simpática renal. É igualmente feita uma atualização dos resultados de estudos experimentais e clínicos, bem como de potenciais futuras indicações desta técnica de intervenção noutras doenças do foro cardiovascular.
