When Add-On Medical Therapy Fails to Control Stable Angina Symptoms

Some patients with stable angina continue to experience persistent symptoms despite optimised guideline-directed medical treatment, including escalation to add-on agents. This protocol defines the structured next step when that add-on therapy does not achieve adequate symptom control.

Prior Treatment & Failure Condition

Previous step did not meet targets

What was tried: Add-on nicorandil or trimetazidine was initiated. In patients with left ventricular systolic dysfunction (LVEF <40%), add-on ivabradine was also used.

Goal not achieved: Adequate control and relief of angina symptoms was not attained with this regimen — meeting the threshold for escalation to this protocol.

Next-Step Approach

For patients with persistent angina despite medical treatment, a procedure-based intervention targeting the underlying coronary anatomy is the recommended direction — the complete protocol details the criteria, pathway, and decision points.

Clinical goal: improvement and relief of angina symptoms.

In CCS patients with persistent angina or anginal equivalent, despite guideline-directed medical treatment, myocardial revascularization of functionally significant obstructive CAD is recommended to improve symptoms.
