HCM with Angina-Like Chest Pain on Exertion and No LVOTO — What to Do When Oral Nitrates Have Not Improved Symptoms

Clinical scenario

This protocol applies to patients with hypertrophic cardiomyopathy who present with angina-like chest pain on exertion in the absence of left ventricular outflow tract obstruction (LVOTO). The clinical goal is improvement of symptoms.

Previous line — why this step is needed

This is a second-line protocol. An initial course of oral nitrates failed to achieve adequate improvement of symptoms, indicating that a different therapeutic approach is warranted.

Next-step approach (partial)

After oral nitrate failure in this setting, an alternative pharmacological agent targeting symptom relief is available. The specific agent, selection criteria, and full clinical guidance are contained in the structured protocol — accessible via the link below.

Beta-blockers and calcium antagonists (verapamil or diltiazem) should be considered to improve symptoms in patients with angina-like chest pain even in the absence of LVOTO or obstructive CAD.

Ranolazine may be considered to improve symptoms in patients with angina-like chest pain even in the absence of LVOTO or obstructive CAD.
