Chronic refractory angina affects 5-15% of US patients despite optimal treatment. This review explores new drug therapies like L-arginine and ranolazine, plus devices such as enhanced external counterpulsation for managing this condition.
Area of Science:
- Cardiology
- Pharmacology
- Interventional Cardiology
Background:
- Chronic refractory angina impacts 5-15% of the 12 million U.S. patients with chronic angina, persisting despite optimal medical therapy.
- Patients experience persistent angina symptoms alongside objective evidence of myocardial ischemia.
Purpose of the Study:
- To review evolving pharmacological therapies for chronic refractory angina.
- To briefly discuss emerging devices and invasive procedures for managing this condition.
Main Methods:
- Literature review focusing on pharmacological agents.
- Summary of evidence for devices and invasive procedures.
Main Results:
- Key pharmacological therapies reviewed include L-arginine, ivabradine, ranolazine, nicorandil, and trimetazidine.
- Devices and procedures discussed encompass enhanced external counterpulsation, spinal cord stimulation, and transmyocardial revascularization.
Conclusions:
- Several evolving pharmacological and interventional options show promise for managing chronic refractory angina.
- Further research is needed to establish the full efficacy and safety profiles of these novel treatments.
