Cardiovascular Event Recurrence and Costs after First Myocardial Infarction, Ischemic Stroke, or Intracerebral Hemorrhage in Taiwan

摘要


Background/Objectives: We aimed to assess the incidence of recurrent cardiovascular (CV) events after the first myocardial infarction (MI), ischemic stroke (IS), or intracerebral hemorrhage (ICH) and to estimate acute and follow-up medical costs. Methods: Using Taiwan's National Health Insurance Research Database, we identified patients with their first MI, IS, or ICH between 2011 and 2017. The cumulative incidence rates of second CV events (including events of the same type [recurrent] or of the other two types) were estimated. The costs for hospitalization and all-cause follow-up were calculated for the first and recurrent CV events and are presented as median (Q1~Q3) in 2017 US dollars. Results: We identified 70,428 patients with a first MI, 123,857 with a first IS, and 41,347 with a first ICH. The cumulative incidence rates of recurrence during the first year and after six years were 3.9% and 10.1% for MI, 5.3% and 13.8% for IS, and 3.9% and 8.9% for ICH, respectively. For first and recurrent nonfatal events, acute hospitalization costs were $4,729 (3,737~5,985) and $4,459 (2,887~6,026) for MI; $1,136 (756~2,183) and $1,224 (774~2,412) for IS; and $2,985 (1,264~8,831) and $2,170 (1,183~4,675) for ICH, respectively. Total annual costs for nonfatal first events in the first year and second year of follow-up were $2413 (1,393~6,120) and $1,293 (654~2,868) for MI, $2,174 (1,040~5,472) and $1,394 (602~3,265) for IS, and $2,963 (995~8,352) and $1,185 (405~3,937) for ICH, respectively. Conclusion: In patients with a first MI, IS, and ICH, recurrent CV events continue to substantially impact public health and escalate the economic burden.
