Insights
Resistant hypertension, a challenging condition, requires new treatments. Device-based therapies targeting the sympathetic nervous system show promise for improving cardiovascular outcomes in these patients.
Area of Science:
- Cardiology
- Nephrology
- Neurology
Background:
- Hypertension is a leading cardiovascular risk factor, yet control remains suboptimal.
- Resistant hypertension affects a significant patient group and carries a poor prognosis.
- Novel therapeutic strategies are needed to reduce cardiovascular risk.
Purpose of the Study:
- To review clinical aspects of resistant hypertension.
- To explore the role of autonomic modulation in hypertension treatment.
- To evaluate device-based therapies for resistant hypertension.
Main Methods:
- Literature review of clinical studies and physiological mechanisms.
- Analysis of physiopathological basis of autonomic nervous system in hypertension.
- Assessment of efficacy and safety data for device-based therapies.
Main Results:
- Resistant hypertension is prevalent and linked to worse cardiovascular outcomes.
- The sympathetic nervous system plays a key role in hypertension.
- Renal denervation and baroceptor-activating therapy are emerging non-pharmacological options.
Conclusions:
- Device-based therapies targeting the sympathetic nervous system offer new avenues for resistant hypertension.
- Further research is needed to establish long-term efficacy and safety.
- Autonomic modulation presents a promising frontier in hypertension management.
Abstract:
Hypertension is universally considered the most detrimental among cardiovascular risk factors. Despite the overwhelming evidence of benefits deriving from lowering blood pressure, its control among the hypertensive population is still unsatisfactory. Resistant hypertension has a non negligible prevalence among hypertensive patients, and it is associated with a worse cardiovascular prognosis. There is need of new therapeutic approaches for reducing cardiovascular risk in this population. Sympathetic nervous system is known to play a major role in development and maintenance of essential hypertension, thus in the past decades several efforts have been made to counteract its overactivation. Novel non-pharmacological, promising approaches targeting sympathetic nervous system are now available, such as renal denervation and baroceptor-activating therapy. This review is aimed at describing essential clinical aspects of resistant hypertension, physiopatological basis of autonomic modulation as a target for hypertension treatment, and the available clinical evidence about efficacy and safety of device-based therapies for resistant hypertension. Present limitations and future perspectives were also considered.
