Stable Angina: When Initial Beta-Blocker and/or CCB Therapy Does Not Adequately Control Symptoms

Patients with stable angina who do not achieve adequate symptom relief — or fail to reach target heart rate goals — on first-line antianginal treatment require a defined next-line approach. This protocol addresses that specific clinical situation.

Previous Treatment — Why Escalation Is Needed

Initial therapy combining short-acting nitrates for immediate relief with a beta-blocker and/or a calcium channel blocker (CCB) did not achieve its targets: lowering resting heart rate to 55–60 beats per minute and adequate control of angina symptoms. This failure to reach those goals is the trigger for the next treatment step.

Next-Line Approach (Partial Overview)

The next step centres on a combination of antianginal drug classes — pairing a beta-blocker with a dihydropyridine CCB — and, where needed, the addition of further therapeutic options. The complete selection criteria, sequencing, and management of tolerance are detailed in the full protocol.

Clinical goal: Adequate control and relief of angina symptoms.

If anginal symptoms are not successfully controlled by initial treatment with a beta-blocker or a CCB alone, the combination of a beta-blocker and a DHP-CCB should be considered, unless contraindicated.

Long-acting nitrates or ranolazine should be considered as add-on therapy in patients with inadequate control of symptoms while on treatment with beta-blockers and/or CCBs, or as part of initial treatment in properly selected patients.

When long-acting nitrates are prescribed, a nitrate-free or low-nitrate interval should be considered to reduce tolerance.
