Cardiovascular Disease Burden: Evolving Knowledge of Risk Factors in Myocardial Infarction and Stroke through Population-Based Research and Perspectives in Global Prevention

Current knowledge and research perspectives on the top ranking causes of mortality worldwide, i.e., ischemic heart disease and cerebrovascular diseases have developed rapidly. In fact, until recently, the evidence describing the incidence of acute myocardial infarction, the underlying risk factors, and the clinical outcomes of those who have this acute ischemic coronary event has largely been based on studies conducted in developed countries, with limited data for women and usually of low-ethnic diversity. Recent reports by the WHO have provided striking public health information, i.e., the global burden of cardiovascular mortality for the next decades is expected to predominantly occur among developing countries. Therefore, multiethnic population-based research including prospective cohorts and, when appropriate, case–control studies, is warranted. These studies should be specifically designed to ascertain key public health measures, such as geographic variations in non-communicable diseases, diagnosis of traditional and potential newly discovered risk factors, causes of death and disability, and gaps for improvement in healthcare prevention (both primary and secondary) and specific treatments. As an example, a multinational, multiethnic population-based cohort study is the Prospective Urban and Rural Epidemiology study, which is the largest global initiative of nearly 200,000 adults aged 35–70 years, looking at environmental, societal, and biological influences on obesity and chronic health conditions, such as ischemic heart disease, stroke, and cancer among urban and rural communities in low-, middle-, and high-income countries, with national, community, household, and individual-level data. Implementation of population-based strategies is crucial to optimizing limited health system resources while improving care and cardiovascular morbidity and mortality.
