Attitudes to and Attendance at Cardiac Rehabilitation After Spontaneous Coronary Artery Dissection.

Abstract

Purpose: Cardiac rehabilitation (CR) is standard care for patients after a heart event, including acute myocardial infarction. However, the uptake and relevance of traditional CR after acute myocardial infarction due to spontaneous coronary artery dissection (SCAD) has not been extensively investigated. The present study investigated attitudes toward CR, identified the rate and correlates of CR attendance, and examined the reasons for CR non-attendance after SCAD.

Methods: Online focus groups (n = 30) explored attitudes toward and experiences of CR of survivors of SCAD, with data analyzed thematically according to recommended guidelines. An online survey (n = 310) then investigated rates of CR attendance and reasons for non-attendance. Correlates of CR attendance were identified using bivariate and multivariable analyses.

Results: Thematic analysis revealed 5 themes in the perceptions of CR of survivors of SCAD: (1) lack of relevance of CR educational content; (2) lack of identification with typical CR attendees; (3) lack of CR health professional knowledge and skills; (4) preference for SCAD-specific CR; and (5) benefits of CR. The survey demonstrated a CR attendance rate of 63% (73% among those referred). The correlates of CR attendance were mid-level education and self-reported lifetime anxiety. Among attendees, the correlates of attending fewer sessions were having a more recent SCAD, not having lifetime anxiety, and not knowing other survivors of SCAD. Reported reasons for non-attendance mirrored qualitative themes identified.

Conclusion: While the survey demonstrated high CR attendance, perceptions that CR was unnecessary and irrelevant after SCAD were evident, often based on health professional advice. The findings add to the growing literature highlighting a need for appropriate support for survivors of SCAD.
