Conclusions: In the same number of people treated, the number of CVD events avoided for the overall risk approach is always larger than that of the blood pressure approach. The additional benefits of overall risk approach compared with the blood pressure approach decreases as the percentage of people from the total population is increased. If the current practice and hypertension guidelines in China are shifted to the overall risk approach, many more CVD events could be avoided with the same resources used. / Methods: The sample used in the analyses includes a subsample of 38,673 persons from the 2002 China National Nutrition and Health Survey, who were 30-74 years old, without previous CVD, and had data on all major CVD risk factors. CVD risks of the patients selected by each approach are predicted using suitable risk prediction equation. The RRR of anti-hypertensive drug treatment derived from meta-analyses of RCTs. The difference in the absolute effectiveness between the two approaches is used to quantify how many more CVD events can be prevented in 1000 people treated by the ORA as compared to the BPA. / Objective: To estimate and compare the number of major cardiovascular events that could be avoided by shifting the blood pressure approach to the overall risk approach if the same percentage of people in a large, representative Chinese population is treated with anti-hypertensive drugs. / Results: When 2.5%, 5.5%, 10.1%, 15.5%, 20.7%, 25.7% or 33.0% of the 38,673 subjects were treated by anti-hypertensive drugs by using the two approaches respectively, 22 (95%CI: 17∼28), 13 (11∼16), 9 (8∼10), 7 (6∼8), 6 (5∼7), 5 (4∼6), or 4 (3∼4) more CVD events could be avoided in every 1000 people treated if the blood pressure approach is shifted to the overall risk approach, which is in general a 15% to 25% increase in CVD events prevented. / Qin, Ying. / Adviser: Jin Ling Tang. / Source: Dissertation Abstracts International, Volume: 73-02, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 116-121). / Electronic reproduction.
