Predictions of the disease’s future prevalence are a crucial component of health policy-makers budget preparation and of significant interest to persons with a family history of cardiovascular disease (CVD). Researchers from Japan have now forecast a decline in CVD incidence through 2040 using new statistical modelling techniques. Governments need projections of disease rates to determine how much money will be needed for healthcare in the future and for what health priorities. However, due to the wide range of variables that affect disease rates, it might be difficult to make precise projections. According to a study that will be published in The Lancet Regional Health – Western Pacific, there may be a decline in coronary heart disease (CHD) and stroke deaths in Japan between 2020 and 2040.
