Abstract

Abstract: The 2017 guidelines on the diagnosis and treatment of high blood pressure in adults were published by the American College of Cardiology and the American Heart Association. The impact on clinical outcomes and costs needs to be estimated prior to adopting these guidelines in China. Data from a nationally representative sample in China were analyzed. The prevalence and treatment were calculated based on the criteria of the 2017 guidelines and 2018 Chinese guidelines among participants aged ≥35 years old. Direct medical costs, as well as the averted disability adjusted of life years and cost saving from cardiovascular disease events prevented by controlling hypertension, were also estimated. The prevalence and treatment rate of hypertension were 32.0% and 43.4% according to the 2018 Chinese guidelines. Based on the 2017 guidelines, another 24.5% of the adult population (estimated 168.1 million) would be classified as having hypertension; of whom, about 32.1 million would need to be pharmaceutically treated to reach the current treatment rate of 43.4%. As a result, an estimated additional 42.7 billion US dollars of the direct medical cost would be required for lifetime therapy. By preventing cardiovascular events, the new guidelines would reduce lifetime costs by 3.77 billion US dollars, while preventing 1.41 million disability adjusted of life years lost. Application of the 2017 guidelines in China will substantially increase the prevalence of hypertension and produce a large increase in therapy costs, although it would prevent cardiovascular disease events and save disability adjusted of life years.
