Background Chinese immigrants are at an increased risk for cardiovascular diseases (CVDs) compared with Chinese nationals partly because of lifestyle changes and knowledge deficits. Translated patient resources are available on the Internet and are often provided by health professionals; however, the quality and cultural sensitivity of these resources have not been reported. Objective The aim of this study was to assess the availability, quality, and cultural sensitivity of Chinese-language information available from national Heart Foundations (cardiac research bodies, nongovernmental organisations) of the 5 most popular destinations of Chinese immigration. Methods This study is a descriptive research in which national Heart Foundation websites were systematically searched for Chinese-language CVD patient education resources. Quality (content, identification, structure) was assessed using the Ensuring Quality Information for Patients instrument. Cultural sensitivity was evaluated using the Cultural Sensitivity Assessment Tool. Results From 107 identified resources, 33 were CVD specific: coronary heart disease (n = 20), arrhythmias (n = 7), and heart failure (n = 6). Quality of resources was adequate (mean Ensuring Quality Information for Patients score, 69%), but scores varied significantly (min, 60%; max, 85%). Although all resources were classified as culturally sensitive (Cultural Sensitivity Assessment Tool score ≥ 2.5), 2 resources scored low (≤2.5) for visual impact, and across all resources, written and visual domains were assessed as least culturally sensitive. Most resources lacked culturally specific references. Conclusions Chinese-language CVD resources were inconsistent in the supply of key information. Quality and level of cultural sensitivity were adequate, but most resources lacked culturally specific references. Comprehensive, high-quality CVD resources powered by Editorial Manager and ProduXion Manager from Aries Systems Corporation tailored for Chinese immigrants are urgently needed for healthcare providers to support CVD education and care of patients belonging to this population.
