Abstract:
Objective:To compare the consistency and accuracy of using 2 criteria for decision making of aspirin use for the primary prevention of ischemic cardiovascular disease (ISCVD) and explore the current status and related factors of aspirin use for the primary prevention of ISCVD in Chinese outpatients.
Methods:This cross-sectional study enrolled 3 018 outpatients with hypertension, diabetes, or hypercholesterolemia, who visited the General Practice (GP) clinics of Anzhen hospital in Beijing from September to December 2015 were enrolled in. The information of risk factors for ISCVD and use of aspirin was collected. Both quantitative and qualitative criteria were used to make the decision of aspirin use for primary prevention of ISCVD in this patient cohort. Quantitative criteria were derived from the 2011 Chinese guideline of cardiovascular disease prevention: aspirin use for primary cardiovascular disease prevention in population with risk of ISCVD in the next 10 years≥10%. Qualitative criteria were derived from the Chinese expert consensus on the aspirin use issued in 2013: aspirin should be given for the purpose of primary ISCVD in population with≥3 risk factors:(1) men aged ≥50 years or postmenopausal women; (2) hypertensive subjects with blood pressure ≤150/90 mmHg(1 mmHg=0.133 kPa);(3) diabetes; (4) hypocholesteremia; (5) obesity with body mass index (BMI)≥28 kg/m2; (6) Smokers;(7) with familiar premature ISCVD history (male<55 years, female<65 years). Demographic data of participants were obtained by questionnaire, on-site measurements or screening previous medical records.
Results:67.1% participants (n=2 024) should be recommended to take aspirin as primary prevention medication using 10-year risk of ISCVD≥10% as the criteria, and 77.9% participants (n=2 350) should be recommended to take aspirin as primary prevention medication using number of risk factors≥3 as the criteria. With 10-year risk of ISCVD≥10% as the gold standard and risk factors≥3 as the evaluation criteria, the sensitivity was 97%, specificity was 61%, the consistency rate was 85%, Kappa value was 0.628 (U=35.824, P<0.001) , indicating that the consistency of the 2 criteria was good. The percentage of real-world aspirin use for primary prevention of ISCVD in this cohort was significantly higher for participants evaluated with the 10-year risk of ISCVD≥10% than that evaluated with 3 risk factors (53.1% vs. 49.2%, χ2=6.523, P=0.011). 12.7% participants with 10-year risk of ISCVD<10% and 6.6% participants with<3 risk factors took aspirin for the primary prevention of ISCVD in this cohort. Age, smoking, hypertension, diabetes and hypercholesterolemia were significantly related to the aspirin use in this cohort, relative ORs were 1.047 (95%CI 1.035-1.060) , 1.969 (95%CI 1.403-2.762) , 2.065 (95%CI 1.623-3.629) , 3.493 (95%CI 2.726-4.475, and 1.344 (95%CI 1.109-1.628) , respectively. Obesity and familial history of premature ISCVD were not related to the aspirin use, relative ORs were 1.137 (95%CI 0.828-1.562) and 0.986 (95%CI 0.767-1.266) .
Conclusions:The consistency of the 2 criteria for decision making of aspirin use for the primary prevention of ISCVD is good and about 50% participants who should be recommended to the use of aspirin for the primary prevention of ISCVD took the aspirin in the real-world scenario. The use of aspirin as primary prevention strategy for ISCVD in the real-world scenario is related to age, smoking, hypertension, diabetes and hypercholesterolemia.
