Insights
Percutaneous Coronary Intervention (PCI) plus medical therapy significantly reduced the risk of death and acute coronary syndrome (ACS) compared to medical therapy alone in stable low-risk coronary artery disease (CAD). PCI improved long-term prognosis by stabilizing lesions and reducing stenosis.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Trials
Context:
- Stable low-risk coronary artery disease (CAD) requires effective long-term management strategies.
- The optimal treatment approach, balancing percutaneous coronary intervention (PCI) with medical therapy versus medical therapy alone, remains an area of investigation.
- Previous trials like the COURAGE trial have provided valuable insights but further research is needed for specific patient populations.
Purpose:
- To compare the long-term prognoses of percutaneous coronary intervention (PCI) plus medical therapy (P) versus medical therapy (M) alone in patients with stable low-risk coronary artery disease (CAD).
- To evaluate the effectiveness of PCI in reducing the cumulative risk of death and acute coronary syndrome (ACS).
- To investigate the incidence of ACS originating from PCI-target lesions.
Summary:
- A randomized trial (JSAP Study) compared PCI plus medical therapy (P) with medical therapy alone (M) in stable low-risk CAD patients.
- The cumulative risk of death plus ACS was significantly lower in the PCI group (P).
- The incidence of ACS originating from the PCI-target lesion was also significantly lower in the PCI group.
Impact:
- PCI therapy may offer improved long-term prognosis in stable low-risk CAD by stabilizing target lesions and reducing stenosis, potentially preventing future ACS events.
- These findings suggest PCI could be a more effective strategy than medical therapy alone for certain CAD patients, contrasting with some previous trial outcomes.
- The study highlights the importance of considering lesion stabilization and stenosis reduction as mechanisms for improved outcomes in CAD management.
Abstract:
We conducted a randomized trial in which the long-term prognoses obtained with PCI+ medical therapy (P) and Medical therapy only (M) were compared in patients with stable low-risk CAD (JSAP Study). The cumulative risk of death+ACS was significantly smaller in the P group. The incidence of ACS stemming from the PCI-target lesion was significantly lower in the P group. A considerable number of ACS cases may originate from coronary sites with already severe stenosis makes it reasonable to expect that PCI therapy would protect against a future ACS attack by stabilizing the PCI-target lesion as well as reducing stenosis. Therefore, P may improve long-term prognosis more effectively than M, which is different from the result of COURAGE Trial.
