Editorial Commentary: Treatment of Refractory Angina: An Ongoing Challenge

The term refractory angina implies that the episodes of angina are recurrent and incapacitating despite conventional treatment [1]. It is also assumed that anemia, thyrotoxicosis, arrhythmias, uncontrolled hypertension, and other comorbid conditions that may aggravate angina and myocardial ischemia are absent or, if present, are adequately treated before labeling the patient as having refractory angina [1]. Patients with refractory angina remain symptomatic despite treatment with antianginal drugs and their coronary artery disease is unsuitable for revascularization [1].
