Insights
Chronic stable angina is increasing, offering a key opportunity for early treatment to reduce mortality. This review covers current and emerging therapies for refractory angina symptoms.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Chronic stable angina incidence is rising, affecting millions in the US and Europe.
- Optimal medical therapy is crucial for all stages of coronary artery disease.
- Stable angina diagnosis is a critical window for initiating life-saving, evidence-based treatments.
Purpose of the Study:
- To review the pathophysiology of chronic stable angina.
- To outline current clinical management strategies.
- To discuss emerging therapies for refractory symptoms.
Main Methods:
- Literature review of pathophysiology.
- Analysis of current clinical guidelines.
- Exploration of novel therapeutic approaches.
Main Results:
- Chronic stable angina requires optimal medical therapy and potentially revascularization.
- Refractory angina remains a challenge despite standard treatments.
- Emerging therapies aim to improve symptom management and patient outcomes.
Conclusions:
- Early diagnosis and treatment of stable angina are vital for reducing mortality.
- Aggressive medical management is the cornerstone of care.
- Further research into novel therapies is needed for refractory cases.
Abstract:
The incidence of chronic stable angina has risen significantly over the past few decades and may affect as many as 15,000-40,000 individuals per million in the US and Europe. Whereas there are fundamental pathophysiologic differences between chronic stable angina and acute coronary syndrome, the importance of optimal medical therapy in all stages of coronary artery disease cannot be overemphasized. As the initial manifestation of coronary artery disease in nearly half of all patients, diagnosis of stable angina represents a valuable opportunity to initiate evidence-based therapies to decrease mortality among patients with coronary artery disease, in addition to symptomatic treatment. However, despite aggressive medical therapy and if appropriate, revascularization, many patients still have refractory angina. In this article, the pathophysiology, currently recommended clinical management and emerging therapies to treat symptoms of chronic stable angina are reviewed.
