The purpose of this research was to was to create a well-functioning, cost-effective, hypertension control program in China.  Hypertension is the leading cause for cardiovascular disease in China.  Today, there is about 325 million people in China with hypertension.  Only 34% of these Chinese adults are treated with medication.  Most Chinese patients pay for meds out-of-pocket, but the government provides many antihypertensive medications for free.  The authors hypothesized that they would be able to create a program to control hypertension in China if researchers used a computer simulation model to analyze data.  Chinese researches used The Cardiovascular Disease Policy Model-China, a computer simulation model to balance factors including the costs of different medications, severity levels of hypertension, and additional risks.  Computerized tests were run to ultimately show that treating untreated hypertension Chinese adults  could prevent approximately 800,000 cardiovascular disease events, annually.  This was cost-effective in over 63% of simulations.  A cost-effective hypertension control program was created in China.
