ABSTRACT
OBJECTIVES:
To describe the occurrence of recurrent atherosclerotic cardiovascular disease (ASCVD) events within 3 years after a new-onset event, the associated disease burden and statin prescribing in patients with ASCVD in Taiwan.DESIGN:
Retrospective cohort study.SETTING:
This was a retrospective cohort study using Taiwan's National Health Insurance Research Database.PARTICIPANTS:
In total, 111 399, 133 538 and 21 572 patients who were hospitalised with diagnosis of coronary heart disease (CHD), cerebrovascular disease (CBVD) and peripheral artery disease (PAD), respectively, between 1 January 2012 and 31 December 2014. PRIMARY AND SECONDARY OUTCOMEMEASURES:
For each index and recurrent event, patients were observed for 12 months after admission to quantify risks of mortality, recurrent events, statin treatment and healthcare use.RESULTS:
We identified 97 321, 120 914 and 14 794 patients with new-onset CHD, CBVD and PAD, respectively. The proportions of developing first, second and third recurrent events were 22.5%, 25.6% and 30.9% for CHD; 20.9%, 26.2% and 32.4% for CBVD and 40.2%, 41.4% and 43.6% for PAD, respectively. Most patients had the same type of ASCVD for their recurrent events as their new-onset event. The mortality rates increased with each recurrent event (p<0.05 for all three ASCVD groups). The rates of hospital readmission and emergency room (ER) visit increased with increasing recurrent events. For example, in the CHD group, the 1-year readmission rates following the index, first and second recurrent events were 43.1%, 47.6% and 55.3%, respectively, and the proportions of visiting ER were 46.4%, 51.9% and 57.8%, respectively. Statin prescribing was suboptimal at time of index event and recurrent events.CONCLUSION:
Recurrent ASCVD events were associated with a higher risk of recurrent event and mortality and greater healthcare use. However, statin prescriptions at index event and after each recurrent event were suboptimal.Palavras-chave
