Self-care behaviours of first-generation Chinese immigrants living with cardiovascular disease: A qualitative study

AIM

To 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.

DESIGN

A qualitative descriptive design.

METHODS

Individual 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.

RESULTS

Twenty 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.

CONCLUSION

Diverse 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.

IMPACT

Study 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.

Chinese community centre managers contributed to data collection by supporting participant recruitment.

Sex differences in treatment and outcomes amongst myocardial infarction patients presenting with and without obstructive coronary arteries: a prospective multicentre study

Aims

Women have an increased prevalence of myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA). Whether sex differences exist in the outcomes of patients with MI and obstructive coronary arteries (MIOCA) vs. MINOCA remains unclear. We describe sex-based differences in diagnosis, treatment, and clinical outcomes of patients with MINOCA vs. MIOCA.

Methods and results

A large-scale cohort study of patients with ST/non-ST elevation MI undergoing coronary angiography (01/2015-12/2019). Patient demographics, diagnosis, prescribed discharge medications, in-hospital complications, and follow-up data were prospectively collected. A total of 13 202 participants were included (males 68.2% and females 31.8%). 10.9% were diagnosed with MINOCA. Median follow-up was 4.62 years. Females (44.8%) were as commonly diagnosed with MINOCA as males (55.2%), unlike the male preponderance in MIOCA (male, 69.8%; female, 30.2%). Less secondary prevention medications were prescribed at discharge for MINOCA than MIOCA. There was no difference in mortality risk between MINOCA and MIOCA [in-hospital: adjusted odds ratio (OR) 1.32, 95% confidence interval (CI) 0.74-2.35, P = 0.350; long term: adjusted hazard ratio (HR) 1.03, 95% CI 0.81-1.31, P = 0.813]. MINOCA patients had reduced mortality at long-term follow-up if prescribed secondary prevention medications (aHR 0.64, 95% CI 0.47-0.87, P = 0.004). Females diagnosed with MIOCA had greater odds of in-hospital and 1-year mortality than males (aOR 1.50, 95% CI 1.09-2.07, P = 0.014; aHR 1.18, 95% CI 1.01-1.38, P = 0.048).

Conclusion

MINOCA patients have similar mortality rates as MIOCA patients. MINOCA patients were less likely than those with MIOCA to be discharged with guideline-recommended secondary prevention therapy; however, those with MINOCA who received secondary prevention survived longer. Females with MIOCA experienced higher mortality rates vs. males.

Self-care behaviours and related cultural factors among Chinese immigrants with cardiovascular disease in western countries: an integrative review

AIMS AND OBJECTIVES

This review aimed to demonstrate the self-care behaviours of first-generation Chinese immigrants with cardiovascular disease in western countries and identify related cultural factors.

BACKGROUND

Self-care is the cornerstone to mitigate disease symptoms and maintain health status. Chinese immigrants to western countries, operating within a cross-cultural context, may find self-care to manage their cardiovascular disease challenging.

DESIGN

An integrative review was conducted.

METHODS

Seven databases were searched Scopus, ProQuest Health & Medicine, Medline (Ovid), Embase (Ovid), AMED (Ovid), PsycINFO and CINAHL, with output limited to peer-reviewed studies published from 2000 to 2020 in English or Chinese. Initially, 2037 papers were screened. Six papers were retained and critiqued using the Joanna Briggs Institute critical appraisal tools. Deductive and inductive approaches were utilised to analyse the findings. The PRISMA 2020 checklist informed review reportage.

RESULT

In general, Chinese immigrants with cardiovascular disease took an active role in management of their cardiovascular disease, including through diet and activity adaptation and adherence to western medication. Families also played a significant role in disease decision-making and management. However, language and cultural barriers impeded their access to health information and resources in host countries.

RELEVANCE TO CLINICAL PRACTICE

Understanding self-care behaviours and associated cultural factors among Chinese immigrants with cardiovascular disease is important to improve nurses' culturally sensitive practices and provide tailored health education interventions to promote self-care behaviours among immigrant populations. The scarcity of literature on self-care behaviours among Chinese first-generation immigrants with cardiovascular disease indicates the need for further research in this area. Development of culturally and linguistically sensitive health resources and education programs is urgently needed.

Myocardial Infarction With Nonobstructive Coronary Arteries

Myocardial infarction with nonobstructive coronary arteries (MINOCA) is the current term used to describe patients who have a myocardial infarction but have normal, non-obstructed coronary arteries on a coronary angiogram. There is still much debate over the definition, diagnosis, management and treatment of MINOCA. However, MINOCA is not a benign condition; prompt recognition and diagnosis can lead to better management and treatment and thus improve patient outcomes. This review article will update the most recent definition of MINOCA, discuss epidemiology and etiology, and review the diagnostic workup and management options for patients presenting with signs and symptoms of MINOCA.
