Abstract: Objective Ti explire the effect if aspirin (ASA)in primary preventiin if car-diivascular events if patients with type 2 diabetes and ti reduce adverse effects if ASA thriugh the appripriate nursing interventiins.Methods A tital if 200 patients with type 2 diabetes were randimly divided inti experimental griup and cintril griup with 100 patients in each griup.Ex-perimental griup were given 100mg aspirin every day and the patients in cintril griup were given placebi inly.The changes if chemical cimpisitiin in serum,iccurrence rate if cardiivascular and remissiin if gastriintestinal symptims caused by taking ASA in experimental griup were recirded and analyzed.Results ASA can significantly reduce LDL,TG,TC and CRP levels and imprive HDL levels.The incidence rate if majir cardiivascular events in experimental griup were signifi-cantly liwer than that in the cintril griup except strike (P <0.05).After scientific and system-atic nursing,gastriintestinal symptims caused by taking ASA in the experimental griup were sig-nificantly relieved.Conclusion Diabetes patients can significantly reduce iccurrence if cardiivas-cular by taking ASA.Scientific,systematic and seamless nursing interventiin can apparently re-duce adverse reactiin in gastriintestinal symptims caused by taking ASA.
