Low-dose aspirin is increasingly used for the primary prevention of cardiovascular events. However, current evidence suggests that the gastrointestinal and other bleeding risks of aspirin probably outweigh its potential benefits in primary prevention. Various strategies have been proposed to reduce the gastrointestinal risk of aspirin, including gastroprotection with a proton pump inhibitor (PPI), eradication of Helicobacter pylori infection and replacing aspirin with other anti-platelet agents. Although co-therapy with a PPI and the eradication of H. pylori substantially reduce the risk of recurrent ulcer bleeding with aspirin, the replacement of aspirin by clopidogrel cannot be recommended to patients with a high gastrointestinal risk. Traditionally, strategies for the prevention of non-steroidal anti-inflammatory drug (NSAID)-induced ulcer complications included co-therapy with a gastroprotective agent and the substitution of cyclooxygenase (COX)-2 inhibitors for non-selective NSAID. Evidence emerged recently that COX-2 inhibitors and some non-selective NSAID increase cardiovascular risk. Before prescribing anti-inflammatory therapy, both gastrointestinal and cardiovascular risk factors of individual patients need to be evaluated. In patients with increased cardiovascular risk requiring anti-inflammatory analgesics, the combination of a non-selective NSAID, low-dose aspirin and a PPI is the preferred treatment.
低剂量阿司匹林越来越多地用于心血管事件的一级预防。然而,目前的证据表明,阿司匹林的胃肠道及其他出血风险可能超过其在一级预防中的潜在益处。已提出多种策略来降低阿司匹林的胃肠道风险,包括使用质子泵抑制剂(PPI)进行胃保护、根除幽门螺杆菌感染以及用其他抗血小板药物替代阿司匹林。尽管PPI联合治疗和根除幽门螺杆菌可大幅降低阿司匹林导致复发性溃疡出血的风险,但对于胃肠道风险高的患者,不建议用氯吡格雷替代阿司匹林。传统上,预防非甾体抗炎药(NSAID)引起的溃疡并发症的策略包括与胃保护剂联合治疗以及用环氧化酶(COX)-2抑制剂替代非选择性NSAID。最近有证据表明,COX-2抑制剂和一些非选择性NSAID会增加心血管风险。在开具抗炎治疗药物之前,需要评估个体患者的胃肠道和心血管危险因素。对于心血管风险增加且需要抗炎镇痛药的患者,非选择性NSAID、低剂量阿司匹林和PPI联合使用是首选治疗方法。
