AimTo identify and describe self‐care behaviours performed by Chinese immigrants living with cardiovascular disease in Australia, and factors perceived as barriers and facilitators to evidence‐based cardiac self‐care.DesignA qualitative descriptive design.MethodsIndividual semi‐structured phone interviews were conducted among participants meeting the following criteria: (1) first‐generation Chinese immigrants to Australia, born in Mainland China, Hong Kong, Macao or Taiwan; (2) Australian permanent residents or citizens; (3) self‐reported or medically diagnosed with coronary heart disease, stroke or heart failure; (4) able to speak English or Mandarin; (5) able to provide informed consent, excluding those with history or evidence of impaired cognition such as dementia. Participants were recruited via social media, Chinese community associations and medical centres from September 2021 to June 2022. Data were analysed using inductive and deductive thematic analysis, guided by the Middle‐Range Theory of Self‐Care of Chronic Illness. The study was reported in line with the COREQ checklist.ResultsTwenty participants were interviewed, 60% female, mean age 69.9 years. Most migrated to Australia at older age following their retirement in China; most had limited English proficiency. Many practiced adequate self‐care for their CVD in self‐care maintenance and monitoring. Variously, they adopted heart‐healthy diets, developed exercise routines, attended medical services and closely monitored their body signs and symptoms. However, self‐adjusting medications, taking Traditional Chinese Medicine and self‐administering health supplements were prevalent practices and first‐response management of acute cardiac symptoms was suboptimal. Linguistic and cultural barriers to obtaining mainstream heart health information meant most participants resorted to informal, anecdotal and mainland Chinese sources.ConclusionDiverse factors were held responsible for sub‐optimal self‐care behaviours but lack of access to linguistically and culturally appropriate heart health information was widely blamed. Linguistically and culturally appropriate community‐based heart health education programmes are urgently needed, targeting healthy lifestyle modification, medication literacy and cardiac symptom management.ImpactStudy findings can be used to improve cardiac nurses' cultural sensitivity and practices targeting Chinese immigrants. Partnering with Chinese community associations offers health service providers and policymakers an innovative route to co‐design and deliver targeted heart health education interventions and support for this population.Public ContributionChinese community centre managers contributed to data collection by supporting participant recruitment.
