Despite the effectiveness of early diagnostic and treatment options, patient screening, disease detection and disease progression remain a challenge, resulting in suboptimal outcomes. Consequently, cardiovascular diseases remain underdiagnosed and undertreated, particularly in developing countries. Several barriers, including paucity of recommended cardiovascular health information and low literacy levels, lead to a poor understanding of the importance of intervention in terms of modifiable risk factors as well as treatment adherence. This narrative review focuses on cardiovascular patients' understanding of their disease, and the need for compliance with their medication and lifestyle modifications. Low levels of perception and insufficient knowledge of CVDs among patients continue to be indispensably important factors in health behaviour. Increased awareness of these issues has the potential to improve the effectiveness of the multidisciplinary cardiovascular team and ultimately improve the care provided to these patients.</p>","PeriodicalId":9434,"journal":{"name":"Cardiovascular Journal of Africa","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141154516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
