A multi-disciplinary care pathway improves symptoms, QoL and medication use in refractory angina

Refractory angina (RA) is a growing clinical problem. Long-term mortality is better than expected and focus has shifted to improving symptoms, quality of life and psychological morbidity. We established a dedicated multi-disciplinary care pathway for patients with RA and assessed its effect on psychological outcomes, quality of life and polypharmacy. We reviewed electronic health records to capture demographics, changes in medication use, and patient-related outcome measures (Seattle Angina Questionnaire [SAQ] and Hospital Anxiety and Depression Scale) before and after enrolment.

One hundred and ninety patients were referred to our service. Pre- and post-questionnaire data were available in 83 patients. Anxiety and depression scores significantly improved (p<0.05) as well as quality of life and all subcategories of the SAQ (p<0.0001). Patients were most commonly on three or four anti-anginal drugs. In patients with no demonstrable reversible ischaemia, there was a significant reduction in anti-anginal usage (mean reduction of two drugs) after completion of our pathway (p<0.025).

In conclusion, a dedicated multi-disciplinary pathway for RA is associated with improvements in quality of life, mental health and polypharmacy. An ischaemia-driven method to rationalise medication may reduce polypharmacy in patients with RA, particularly in patients with no demonstrable ischaemia.
