Are coronary stents the best choice for stable angina?

Coronary artery stents have revolutionised the treatment of heart disease, providing life-saving care to millions worldwide.

However, while stents are essential in treating heart attacks, their role in managing stable angina is more contentious. In this blog, we’ll explore why stents may not always be the best solution for stable angina, the potential risks associated with their use, and alternative approaches to managing this condition effectively.

Understanding stable angina

Stable angina, a common symptom of coronary artery disease (narrowed arteries around the heart), is characterised by chest pain or discomfort during physical activity that resolves with rest. This condition develops gradually as blockages form in the coronary arteries, reducing blood flow to the heart. Unlike heart attacks, stable angina is not life-threatening but requires careful management to improve quality of life and reduce the risk of future complications.

Traditionally, stable angina has been managed through lifestyle changes and medications to control symptoms and improve heart health.1 In severe cases or when high-risk features are present, interventions like stents or bypass surgery may be considered.1 However, routine use of stents for stable angina has been increasingly questioned.

The debate around stenting for stable angina

Coronary stents are small metallic mesh tubes inserted into narrowed arteries to improve blood flow. While their use in emergency situations like heart attacks is lifesaving, evidence suggests that stents offer no additional survival benefits over optimal medical therapy for stable angina, with lifestyle changes and medications effectively managing symptoms for most patients without the risks associated with stenting.2,3,4,5

When stents are placed in patients with mild or insignificant blockages, they may face unnecessary risks such as bleeding, heart attack, or stroke.6 Additionally, these unwarranted procedures contribute to increased healthcare costs, often passed on to consumers.

The importance of choosing evidence-based care

Choosing Wisely, an initiative funded by the Australian Government Department of Health and Aged Care, highlights the need to align medical interventions with robust evidence. For stable angina, this means prioritising non-invasive approaches and reserving stenting for cases where clear benefits outweigh the risks. As a patient, you should feel empowered to ask questions, seek second opinions, and actively participate in your treatment plans.

While stents are a cornerstone of cardiovascular care, their use for stable angina should be carefully evaluated.
