- 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: Long-term disease progression following myocardial infarction (MI) is not well understood. We examined the risk of subsequent cardiovascular events in patients discharged after MI in Sweden.METHODS AND RESULTS: This was a retrospective, cohort study linking morbidity, mortality, and medication data from Swedish national registries. Of 108 315 patients admitted to hospital with a primary MI between 1 July 2006 and 30 June 2011 (index MI), 97 254 (89.8%) were alive 1 week after discharge and included in this study. The primary composite endpoint of risk for non-fatal MI, non-fatal stroke, or cardiovascular death was estimated for the first 365 days post-index MI and Day 366 to study completion. Risk and risk factors were assessed by Kaplan-Meier analysis and Cox proportional hazards modelling, respectively. Composite endpoint risk was 18.3% during the first 365 days post-index MI. Age [60-69 vs. <60 years: HR (95% CI): 1.37 (1.30-1.45); 70-79 vs. <60 years: 2.13 (2.03-2.24); >80 vs. <60 years: 3.96 (3.78-4.15)], prior MI [1.44 (1.40-1.49)], stroke [1.49 (1.44-1.54)], diabetes [1.37 (1.34-1.40)], heart failure [1.57 (1.53-1.62)] and no index MI revascularisation [1.88 (1.83-1.93)] were each independently associated with a higher risk of ischaemic events or death. For patients without a combined endpoint event during the first 365 days, composite endpoint risk was 20.0% in the following 36 months.CONCLUSIONS: Risk of cardiovascular events appeared high beyond the first year post-MI, indicating a need for prolonged surveillance, particularly in patients with additional risk factors.

- Objectives To compare short-term cardiovascular (CV) outcome in type 2 diabetes (T2D) patients without ischaemic heart disease (IHD), with IHD but no prior myocardial infarction (MI), and those with prior MI; and assess the impact on risk of age when initiating first-time glucose-lowering drug (GLD). Design Cohort study linking morbidity, mortality and medication data from Swedish national registries. Participants First-time users of GLD during 2007-2016. Outcomes Predicted cumulative incidence for the CV outcome (MI, stroke and CV mortality) was estimated. A Cox model was developed where age at GLD start and CV risk was modelled. Results 260 070 first-time GLD users were included, 221 226 (85%) had no IHD, 16 294 (6%) had stable IHD-prior MI and 22 550 (9%) had IHD+MI. T2D patients without IHD had a lower risk of CV outcome compared with the IHD populations (±prior MI), (3-year incidence 4.78% vs 5.85% and 8.04%). The difference in CV outcome was primarily driven by a relative greater MI risk among the IHD patients. For T2D patients without IHD, an almost linear association between age at start of GLD and relative risk was observed, whereas in IHD patients, the younger (<60 years) patients had a relative greater risk compared with older patients. Conclusions T2D patients without IHD had a lower risk of the CV outcome compared with the T2D populations with IHD, primarily driven by a greater risk of MI. For T2D patients without IHD, an almost linear association between age at start of GLD and relative risk was observed, whereas in IHD patients, the younger patients had a relative greater risk compared with older patients. Our findings suggest that intense risk prevention should be the key strategy in the management of T2D patients, especially for younger patients.

- Overuse of short-acting β2-agonists (SABA) may indicate poor asthma control and adverse health outcomes. Contemporary population-based data on use, risk factors and impact of SABA (over)use on asthma exacerbations and mortality are scarce, prompting initiation of the global SABINA (SABA use IN Asthma) programme.MethodsBy linking data from Swedish national registries, asthma patients aged 12–45 years with two or more collections of drugs for obstructive lung disease during 2006–2014 were included. SABA overuse was defined as collection of more than two SABA canisters in a 1-year baseline period following inclusion. SABA use was grouped into 3–5, 6–10 and ≥11 canisters per baseline-year. Cox regression was used to examine associations between SABA use and exacerbation (hospitalisations and/or oral corticosteroid claims) and mortality.ResultsThe analysis included 365 324 asthma patients (mean age 27.6 years; 55% female); average follow-up was 85.4 months. 30% overused SABA, with 21% collecting 3–5 canisters per year, 7% collecting 6–10 canisters per year and 2% collecting ≥11 canisters per year. Increasing number of collected SABA canisters was associated with increased risk of exacerbation, as follows. 3–5 canisters: hazard ratio (HR) 1.26 (95% CI 1.24–1.28); 6–10 canisters: 1.44 (1.41–1.46); and ≥11 canisters: 1.77 (1.72–1.83), compared to two or fewer canisters per year. Higher SABA use was associated with incrementally increased mortality risk (2564 deaths observed), as follows. 3–5 canisters: HR 1.26 (95% CI 1.14–1.39); 6–10 canisters 1.67 (1.49–1.87); and ≥11 canisters: 2.35 (2.02–2.72) compared to two or fewer canisters per year.ConclusionOne-third of asthma patients in Sweden collected three or more SABA canisters annually. SABA overuse was associated with increased risks of exacerbation and mortality. These findings emphasise that monitoring of SABA usage should be key in improving asthma management.

- 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.

- Objective: Long-term progression of peripheral arterial disease (PAD) as initial manifestation of atherosclerotic arterial disease is not well described. Cardiovascular (CV) risk was examined in different PAD populations diagnosed in a hospital setting in Sweden. Methods: Data for this retrospective cohort study were retrieved by linking data on morbidity, medication use, and mortality from Swedish national registries. Primary CV outcome was a composite of myocardial infarction, ischemic stroke (IS), and CV death. Kaplan-Meier analysis and Cox proportional hazards modeling was used for describing risk and relative risk. Results: Of 66,189 patients with an incident PAD diagnosis (2006-2013), 40,136 had primary PAD, 16,786 had PAD _ coronary heart disease (CHD), 5803 had PAD _IS, and 3464 had PAD _IS _CHD. One-year cumulative incidence rates of major CV events for the groups were 12%, 21%, 29%, and 34%, respectively. Corresponding numbers for 1-year all-cause death were 16%, 22%, 33%, and 35%. Compared with the primary PAD population, the relative risk increase for CV events was highest in patients with PAD _IS _CHD (hazard ratio [HR], 2.01), followed by PAD _IS (HR, 1.87) and PAD _ CHD (HR, 1.42). Despite being younger, the primary PAD population was less intensively treated with secondary preventive drug therapy. Conclusions: PAD as initial manifestation of atherosclerotic disease diagnosed in a hospital-based setting conferred a high risk: one in eight patients experienced a major CV event and one in six patients died within 1 year. Despite younger age and substantial risk of future major CV events, patients with primary PAD received less intensive secondary preventive drug therapy.

- 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.
