- Aims Long-term contemporary nationwide data on resource use and healthcare costs after myocardial infarction (MI) in a clinical practice setting are not widely studied, and the aim of this study was to investigate resource use patterns and healthcare costs in patients with MI in a nationwide clinical practice setting.Methods and results This retrospective cohort study included all patients identified in the compulsory Swedish nationwide patient register with a diagnosis of MI between 1 July 2006 and 30 June 2011. Cardiovascular hospitalization and outpatient visits data from the patient register were combined with data from the cause of death register and the drug utilization register. For a subset of patients, data were also available from a primary care register. Healthcare resource use patterns and annual costs [reported in 2014 euros (€) converted from Swedish kronor (SEK) using the exchange rate €1 = SEK 9.33)] were estimated for the year prior to the occurrence of MI as well as for a maximum follow-up period of 6 years post-MI. The study included 97 252 patients with a diagnosis of MI with a total number of 285 351 observation years. The majority of healthcare consumption occurred within the first year of MI where patients were on average hospitalized 1.55 times, made 1.08 outpatient care visits, and 3.80 primary care visits. In the long term, for the majority of resource use categories, average consumption was higher in the years after MI compared with the year prior to MI. Healthcare costs at 6 years of follow-up were approximately €20 000 of which €12 460 occurred in the first year, and the major part was attributed to hospitalizations.Conclusion For patients with 6 years of follow-up after MI, healthcare costs were approximately €20 000. The major part of costs occurred in the first year after MI and was driven by hospitalizations

- Aims To assess the international validity of using hospital record data to compare long-term outcomes in heart attack survivors.Methods and results We used samples of national, ongoing, unselected record sources to assess three outcomes: cause death; a composite of myocardial infarction (MI), stroke, and all-cause death; and hospitalized bleeding. Patients aged 65 years and older entered the study 1 year following the most recent discharge for acute MI in 2002–11 [n = 54 841 (Sweden), 53 909 (USA), 4653 (England), and 961 (France)]. Across each of the four countries, we found consistent associations with 12 baseline prognostic factors and each of the three outcomes. In each country, we observed high 3-year crude cumulative risks of all-cause death (from 19.6% [England] to 30.2% [USA]); the composite of MI, stroke, or death [from 26.0% (France) to 36.2% (USA)]; and hospitalized bleeding [from 3.1% (France) to 5.3% (USA)]. After adjustments for baseline risk factors, risks were similar across all countries [relative risks (RRs) compared with Sweden not statistically significant], but higher in the USA for all-cause death [RR USA vs. Sweden, 1.14 (95% confidence interval 1.04–1.26)] and hospitalized bleeding [RR USA vs. Sweden, 1.54 (1.21–1.96)].Conclusion The validity of using hospital record data is supported by the consistency of estimates across four countries of a high adjusted risk of death, further MI, and stroke in the chronic phase after MI. The possibility that adjusted risks of mortality and bleeding are higher in the USA warrants further study.

- Peripheral artery disease (PAD) is common worldwide, and PAD patients are increasingly offered lower limb revascularization procedures. The aim of this population-based study was to describe the current risk for cardiovascular (CV) events and mortality and also to elucidate the current pharmacologic treatment patterns in revascularized lower limb PAD patients.This observational, retrospective cohort study analyzed prospectively collected linked data retrieved from mandatory Swedish national health care registries. The Swedish National Registry for Vascular Surgery database was used to identify revascularized PAD patients. Current risk for CV events and death was analyzed, as were prescribed drugs aimed for secondary prevention. A Cox proportional hazard regression model was used to explore risk factors for suffering a CV event.Between May 2008 and December 2013, there were 18,742 revascularized PAD patients identified. Mean age was 70.0years among patients with intermittent claudication (IC; n= 6959) and 76.8years among patients with critical limb ischemia (CLI; n= 11,783). Antiplatelet therapy, statins, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and beta-blockers were used by 73%, 60%, 57%, and 49% at admission for revascularization. CV event rate (a composite of myocardial infarction, ischemic stroke, or CV death) at 12, 24, and 36months was 5.1% (95% confidence interval [CI], 4.5-5.6), 9.5% (95% CI, 8.7-10.3), and 13.8% (95% CI, 12.8-14.8) in patients with IC and 16.8% (95% CI, 16.1-17.6), 25.9% (95% CI, 25.0-26.8), and 34.3% (95% CI, 33.2-35.4) in patients with CLI. Best medical treatment, defined as any antiplatelet or anticoagulant therapy along with statin treatment, was offered to 65% of IC patients and 45% of CLI patients with little change during the study period. Statin therapy was associated with reduced CV events (hazard ratio, 0.76; 95% CI, 0.71-0.81; P< .001), whereas treatment with low-dose aspirin was not.Revascularized PAD patients are still at a high risk for CV events without a declining time trend. A large proportion of both IC and CLI patients were not offered best medical treatment. The most commonly used agent was aspirin, which was not associated with CV event reduction. This study calls for improved medical management and highlights an important and partly unmet medical need among revascularized PAD patients.
