Causes of the burgeoning cardiovascular epidemic in developing countries (DC) are known. Whilst there are many prevention strategies and policies demonstrated to be effective in reducing the trends of cardiovascular disease in developed countries, applying them in DCs is challenging and complex. To utilize resources efficiently, two key decisions have to be made by policy makers in all DCs. The first is to decide on the appropriate mix of population and high-risk interventions. The second is to determine the threshold for implementing high-risk interventions. In making such decisions, due consideration needs to be given to scientific evidence, affordability, sustainability, opportunity costs, and social and political realities. High-risk approaches can be made cost-effective if individuals that are most likely to benefit from treatment can be identified through risk stratification systems. Although several such risk prediction systems are available, they have limited applicability to non-Western populations. Further, health systems in DCs do not have basic infrastructure facilities to support resource intensive risk prediction tools, particularly in primary healthcare. The World Health Organization has developed a flexible cardiovascular disease risk management package that is implemented in a range of less resourced settings. A risk prediction tool that enables more accurate prediction of cardiovascular risk in DCs is in development.
发展中国家心血管疾病迅速蔓延的原因已为人所知。虽然有许多预防策略和政策在发达国家被证明对降低心血管疾病趋势有效,但在发展中国家应用这些策略和政策具有挑战性且复杂。为了有效利用资源,所有发展中国家的政策制定者必须做出两个关键决策。第一个是决定人口干预和高危干预的适当组合。第二个是确定实施高危干预的阈值。在做出这些决策时,需要充分考虑科学证据、可承受性、可持续性、机会成本以及社会和政治现实。如果能够通过风险分层系统识别出最有可能从治疗中受益的个体,那么高危方法可以具有成本效益。虽然有几种这样的风险预测系统,但它们对非西方人群的适用性有限。此外,发展中国家的卫生系统没有基本的基础设施来支持资源密集型的风险预测工具,特别是在初级卫生保健方面。世界卫生组织已经制定了一套灵活的心血管疾病风险管理方案,该方案在一系列资源较少的环境中实施。一种能够更准确预测发展中国家心血管风险的风险预测工具正在研发中。
