[Refractory angina and the role of the Coronary Sinus Reducer implantation technique]

Area of Science:

• Cardiology
• Vascular Medicine
• Pain Management

Background:

• Refractory angina affects 5-10% of coronary artery disease patients.
• Characterized by persistent angina-type pain despite optimal medical therapy.
• Patients are ineligible for or unsuitable for revascularization procedures.

Purpose of the Study:

• To review conventional pharmacological and interventional treatments for refractory angina.
• To explore emerging non-pharmacological therapies targeting neural pain processing and myocardial perfusion.
• To focus on the coronary sinus reducer (CSR) technique, its rationale, and clinical evidence.

Main Methods:

• Literature review of refractory angina treatments.
• Analysis of emerging therapeutic strategies.
• Detailed examination of coronary sinus reducer implantation.

Main Results:

• Conventional therapies offer limited relief for refractory angina.
• Emerging treatments show promise in addressing neural pathways and improving perfusion.
• Coronary sinus reducer implantation presents a novel interventional option with supporting clinical data.

Conclusions:

• Refractory angina requires innovative therapeutic approaches.
• Non-pharmacological and device-based interventions are expanding treatment options.
• The coronary sinus reducer is a viable option for select patients with refractory angina.
