- Abstract
Background and Aims: Utilising real-world data, we quantified the burden of cardiovascular risk factors and long-term residual risk of atherothrombotic events among routine care cohorts with coronary (CAD) or peripheral (PAD) artery disease or ischemic stroke (IS) on guideline-recommended antiplatelet monotherapy (APMT)., Methods: Retrospective cohort study using data (2010-2020) from the United Kingdom Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics, including adults with CAD, PAD or IS who were first prescribed APMT (CAD/IS: aspirin; PAD: clopidogrel). Primary outcomes (recurrent events): major adverse cardiovascular events (MACE) for CAD/PAD/IS cohorts, major adverse limb events (MALE) for PAD., Results: 266,478 CAD, 13,162 PAD, and 14,788 IS patients were included (mean age: 71 years; women 37.7%-47.5 %). Risk factor burden was high and attainment of recommended goals was low. There were 73,691, 3,121 and 7,137 MACE among CAD, PAD and IS patients, respectively (median follow-up: 89.9, 42.4 and 75.9 months, respectively), and 4,767 MALE among PAD patients. MACE incidence rate per 1000 person-years was higher in IS (268.7; 95%CI 265.3-272.0) than CAD (92.9; 95%CI 92.5-93.4) or PAD cohorts (97.2; 95%CI 94.6-99.8). MALE incidence rate was 195.9 (95%CI 192.2-199.6) per 1000 person-years. IS patients presented a lower rate of hospitalisations and longer time-to-first hospitalisation, but once hospitalised, they had a longer length-of-stay. PAD patients had the highest hospitalisation rate., Conclusions: Among a contemporary cohort with cardiovascular disease on APMT, long-term residual atherothrombotic risk remains high despite being on APMT. Greater attention to risk factor control and use of appropriate evidence-based therapy is required to reduce residual risk among this very high-risk population., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: AJVV: personal fees for consulting from Bayer, during the conduct of the study; current or past participation in research grants to Imperial College London from Pfizer, Amgen, Merck Sharp & Dohme, Sanofi-Aventis, Daiichi Sankyo, and Regeneron, outside the submitted work; and personal fees for consulting from Regeneron and honoraria for lectures from Amgen, Mylan, Akcea, and Ferrer, outside the submitted work.
