Resistant hypertension (RH) management is evolving. Device-based treatments targeting the sympathetic nervous system show promise for reducing cardiovascular risks in patients with RH.
Area of Science:
- Cardiology
- Nephrology
- Internal Medicine
Background:
- Resistant hypertension (RH) is defined as uncontrolled blood pressure despite optimal doses of three antihypertensive drugs, including a diuretic.
- RH significantly increases the risk of cardiovascular morbidity and mortality.
- It places a substantial burden on global healthcare systems.
Purpose of the Study:
- To provide a comprehensive overview of resistant hypertension.
- To review current diagnostic strategies for RH.
- To discuss therapeutic approaches for managing RH.
Main Methods:
- Literature review of diagnostic criteria for RH.
- Analysis of recent clinical studies on RH management.
- Evaluation of device-based therapies targeting sympathetic nervous system outflow.
Main Results:
- Device-based treatments for RH demonstrate promising results in reducing sympathetic nervous system activity.
- These interventions may lead to a decrease in adverse cardiovascular outcomes for patients with RH.
- Current diagnostic and therapeutic strategies are being refined.
Conclusions:
- Resistant hypertension requires a multifaceted management approach.
- Device-based therapies represent a promising avenue for RH treatment.
- Further research is ongoing to optimize the care of patients with RH.
