One in 10 ANOCA patients waited over 10 years for a diagnosis, with 92% still experiencing angina and 28% reporting poor quality of life.
Patients with ANOCA face significant diagnostic delays, frequent misdiagnoses, and high rates of ongoing angina that impair quality of life.

Abstract Aim The inadequate patient journey of those with chest pain and no significant blockages (also known as ANOCA; Angina with Non-Obstructive Coronary Arteries) have prompted the formation of support groups, namely the International Heart Spasms Alliance (IHSA). However, there is limited data supporting the ANOCA patient-reported diagnostic journey. Purpose To determine the patient-reported diagnostic journey of those with ANOCA. Methods The IHSA in collaboration with the University of Adelaide researchers launched a web-based series of surveys for patients with ANOCA via social media platforms and cardiologist distribution. The theme of the first survey is diagnosis. Results A total of 694 responses have been collected thus far. The average age was 57 ± 11.0 and 89% of participants were female. Participants were predominantly of a Caucasian ethnicity (92%), and most resided in North America (44%), Europe (38%) or Australia/Oceania (17%). Overall, the underlying patient-reported diagnoses included diseases of the large vessels (35%; i.e. vasospastic angina) small vessels (19%; i.e. coronary microvascular dysfunction), both vessels (36%) or unknown diagnosis (10%). One in 10 participants waited over 10 years from symptom onset to receiving a diagnosis, and 3 in 4 participants were at some stage told that their symptoms were non-cardiac in nature. Only 11% of participants received a diagnosis by the first attending clinician whereas some required over 10 physicians (5%) to receive a diagnosis. Prior to receiving a diagnosis, a quarter of the participants were seen in the emergency room over five times for their symptoms but were discharged without any new treatment or change to treatment. Half of the participants sought treatment from 2 or 3 clinicians after their diagnosis. At this baseline survey, 92% continue to experience angina with 28% reporting a poor quality of life from their symptoms, as assessed by the Seattle Angina Questionnaire. Conclusion Patients with ANOCA are often overlooked and experience delays in their diagnostic journey. Even when receiving a diagnosis, many continue to experience ongoing angina that affects their quality of life. Thus, increased awareness, physician recognition and adequate diagnosis are needed to foster further research and develop evidence-based guidelines for this increasingly recognised cardiovascular disorder.
