- Background - This study assessed sex differences in treatments, all-cause mortality, relative survival, and excess mortality following acute myocardial infarction.Methods and Results - A population-based cohort of all hospitals providing acute myocardial infarction care in Sweden (SWEDEHEART [Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies]) from 2003 to 2013 was included in the analysis. Excess mortality rate ratios (EMRRs), adjusted for clinical characteristics and guideline-indicated treatments after matching by age, sex, and year to background mortality data, were estimated. Although there were no sex differences in all-cause mortality adjusted for age, year of hospitalization, and comorbidities for ST-segment-elevation myocardial infarction (STEMI) and non-STEMI at 1 year (mortality rate ratio: 1.01 [95% confidence interval (CI), 0.96-1.05] and 0.97 [95% CI, 0.95-.99], respectively) and 5 years (mortality rate ratio: 1.03 [95% CI, 0.99-1.07] and 0.97 [95% CI, 0.95-.99], respectively), excess mortality was higher among women compared with men for STEMI and non-STEMI at 1 year (EMRR: 1.89 [95% CI, 1.66-2.16] and 1.20 [95% CI, 1.16-1.24], respectively) and 5 years (EMRR: 1.60 [95% CI, 1.48-1.72] and 1.26 [95% CI, 1.21-1.32], respectively). After further adjustment for the use of guideline-indicated treatments, excess mortality among women with non-STEMI was not significant at 1 year (EMRR: 1.01 [95% CI, 0.97-1.04]) and slightly higher at 5 years (EMRR: 1.07 [95% CI, 1.02-1.12]). For STEMI, adjustment for treatments attenuated the excess mortality for women at 1 year (EMRR: 1.43 [95% CI, 1.26-1.62]) and 5 years (EMRR: 1.31 [95% CI, 1.19-1.43]).Conclusions - Women with acute myocardial infarction did not have statistically different all-cause mortality, but had higher excess mortality compared with men that was attenuated after adjustment for the use of guideline-indicated treatments. This suggests that improved adherence to guideline recommendations for the treatment of acute myocardial infarction may reduce premature cardiovascular death among women.

- Scarce and conflicting evidence exists on whether clopidogrel is effective and whether dual antiplatelet treatment (DAPT) is safe in patients with acute coronary syndrome and chronic kidney disease (CKD). To study this, we performed an observational, prospective, multicenter cohort study of 36,001 patients of the SWEDEHEART registry. The exposure was DAPT prolonged after 3 months versus DAPT stopped at 3 months in consecutive patients with acute coronary syndrome and known serum creatinine. DAPT duration with clopidogrel and aspirin was assessed by dispensed tablets. CKD stages were classified according to estimated glomerular filtration rate (eGFR). Study outcomes were 1) the composite of death, myocardial infarction, or ischemic stroke; 2) bleeding; or 3) the aggregate of these two outcomes within day 111 and 365 from discharge. A longer DAPT duration, as compared with 3-month DAPT, was associated with lower hazard ratios for outcome one in each CKD stratum (eGFR over 60, adjusted hazard ratio [95% confidence interval] 0.76 [0.67-0.85]; eGFR 60 and less, 0.84 [0.73-0.96], of which eGFR between 45 and 60, 0.85 [0.70-1.05], eGFR between 30 and 45, 0.78 [0.62-0.97]; eGFR 30 and less ml/min/1.73 m(2), 0.93 [0.70-1.24]. Bleeding (outcome 2) was in general more common in the longer DAPT group of each aforementioned CKD stratum. Aggregated outcome analysis (outcome 3) similarly favored longer DAPT in each stratum. There was no interaction between DAPT duration and CKD strata for any of the study outcomes. Thus, a prolonged as compared with three-month DAPT was similarly associated with a lower risk of death, stroke, or reinfarction regardless of underlying CKD.

- IMPORTANCE Conflicting evidence exists regarding the association between warfarin treatment, death, and ischemic stroke incidence in patients with advanced chronic kidney disease (CKD) and atrial fibrillation. OBJECTIVE To study outcomes associated with warfarin treatment in relation to kidney function among patients with established cardiovascular disease and atrial fibrillation. DESIGN, SETTING, AND PARTICIPANTS Observational, prospective, multicenter cohort study from the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry (2003-2010), which includes all Swedish hospitals that provide care for acute cardiac diseases. Participants included consecutive survivors of an acute myocardial infarction (MI) with atrial fibrillation and known serum creatinine (N = 24 317), including 21.8% who were prescribed warfarin at discharge. Chronic kidney disease stages were classified according to estimated glomerular filtration rate (eGFR). MAIN OUTCOMES AND MEASURES (1) Composite end point analysis of death, readmission due to MI, or ischemic stroke; (2) bleeding (composite of readmission due to hemorrhagic stroke, gastrointestinal bleeding, bleeding causing anemia, and others); or (3) the aggregate of these 2 outcomes within 1 year from discharge date. RESULTS A total of 5292 patients (21.8%) were treated with warfarin at discharge, and 51.7% had manifest CKD (eGFR <60 mL/min/1.73 m(2) [eGFR(<60)]). Compared with no warfarin use, warfarin was associated with a lower risk of the first composite outcome (n = 9002 events) in each CKD stratum for event rates per 100 person-years: eGFR(>60) event rate, 28.0 for warfarin vs 36.1 for no warfarin; adjusted hazard ratio (HR), 0.73 (95% CI, 0.65 to 0.81); eGFR(>30-60): event rate, 48.5 for warfarin vs 63.8 for no warfarin; HR, 0.73 (95% CI, 0.66 to 0.80); eGFR(>15-30): event rate, 84.3 for warfarin vs 110.1 for no warfarin; HR, 0.84 (95% CI, 0.70-1.02); eGFR(<= 15): event rate, 83.2 for warfarin vs 128.3 for no warfarin; HR, 0.57 (95% CI, 0.37-0.86). The risk of bleeding (n = 1202 events) was not significantly higher in patients treated with warfarin in any CKD stratum for event rates per 100 person-years: eGFR(>60) event rate, 5.0 for warfarin vs 4.8 for no warfarin; HR, 1.10 (95% CI, 0.86-1.41); eGFR(>30-60) event rate, 6.8 forwarfarin vs 6.3 for no warfarin; HR, 1.04 (95% CI, 0.81-1.33); eGFR(>15-30) event rate, 9.3 forwarfarin vs 10.4 for nowarfarin; HR, 0.82 (95% CI, 0.48-1.39); eGFR(<= 15) event rate, 9.1 forwarfarin vs 13.5 for nowarfarin; HR, 0.52 (95% CI, 0.16-1.65). Warfarin use in each CKD stratum was associated with lower hazards of the aggregate outcome (n = 9592 events) for event rates per 100 person-years: eGFR(>60) event rate, 32.1 for warfarin vs 40.0 for no warfarin; HR, 0.76 (95% CI, 0.69-0.84); eGFR(>30-60) event rate, 53.6 forwarfarin vs 69.0 for nowarfarin; HR, 0.75 (95% CI, 0.68-0.82); eGFR(>15-30) event rate, 90.2 forwarfarin vs 117.7 for nowarfarin; HR, 0.82 (95% CI, 0.68-0.99); eGFR(<= 15) event rate, 86.2 forwarfarin vs 138.2 for nowarfarin; HR, 0.55 (95% CI, 0.37-0.83). CONCLUSIONS AND RELEVANCE Warfarin treatment was associated with a lower 1-year risk for the composite outcome of death, MI, and ischemic stroke without a higher risk of bleeding in consecutive acute MI patients with atrial fibrillation. This association was not related to the severity of concurrent CKD.

- Objectives We aimed to analyse outcomes of ticagrelor and clopidogrel stratified by estimated glomerular filtration rate (eGFR) in a large unselected cohort of patients with acute myocardial infarction (MI). Methods We used follow-up data in MI survivors discharged on ticagrelor or clopidogrel enrolled in the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies registry. The association between ticagrelor versus clopidogrel and the primary composite outcome of death, MI or stroke and the secondary outcome rehospitalisation with bleeding diagnosis at 1year, was studied using adjusted Cox proportional hazards models, stratifying after eGFR levels. Results In total, 45 206 patients with MI discharged on clopidogrel (n=33472) or ticagrelor (n=11734) were included. The unadjusted 1-year event rate for the composite endpoint of death, MI or stroke was 7.0%, 18.0% and 48.0% for ticagrelor treatment and 11.0%, 33.0% and 64.0% for clopidogrel treatment in patients with eGFR(>60) (n=33668), eGFR(30-60) (n=9803) and eGFR(<30) (n=1735), respectively. After adjustment, ticagrelor as compared with clopidogrel was associated with a lower 1-year risk of the composite outcome (eGFR(>60): HR 0.87, 95%CI 0.76 to 99, eGFR(30-60): 0.82 (0.70 to 0.97), eGFR(<30): 0.95 (0.69 to 1.29), P for interaction=0.55) and a higher risk of bleeding (eGFR(>60): HR 1.10, 95%CI 0.90 to 1.35, eGFR(30-60): 1.13 (0.84 to 1.51), eGFR(<30): 1.79 (1.00 to 3.21), P for interaction=0.30) across the eGFR strata. Conclusions Treatment with ticagrelor as compared with clopidogrel in patients with MI was associated with lower risk for the composite of death, MI or stroke and a higher bleeding risk across all strata of eGFR. Of caution, bleeding events were more abundant in patients with eGFR(<30).

- Aims To study the association between renal function and outcomes in a nationwide cohort of unselected consecutive patients with stable coronary artery disease (SCAD) symptoms and with a defined coronary anatomy by a coronary angiogram (CA). Methods and results We included 45 348 consecutive patients with available plasma creatinine undergoing CA for suspected SCAD from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). We adjusted for clinical background, severity of CAD and subsequent revascularization in a Cox regression analysis. Patients were followed for a median (interquartile range) time of 2.6 (1.2-4.1) years. The 3-year cumulative probability of death, myocardial infarction (MI), heart failure, and stroke increased from 2.7, 4.6, 4.4, and 2.0% in patients with estimated glomerular function (eGFR) >90 to 39.8, 32.8, 30.2, and 6.2% in patients with eGFR <15. Compared with patients with eGFR > 90 mL/min/m(2), patients with impaired renal function (eGFR 30-59, 15-29, and < 15 mL/min/m(2)) had significantly higher risk of death (HR (95% CI): 1.3 (1.1-1.5), 2.2 (1.6-2.9), 7.7 (6.1-9.8)), MI (1.3 (1.1-1.5), 1.8 (1.4-2.5), 4.0 (3.1-5.1)), and heart failure (1.7 (1.51.9), 2.5 (1.9-3.1), 2.4 (1.8-3.2)), but not of stroke (1.1 (0.9-1.3), 1.1 (0.6-1.7), 1.4 (0.7-2.5)) after multivariable adjustment. For patients with eGFR 60-89, there was no significant difference in the risk of death, MI or stroke but increased risk of heart failure 1.2 (1.1-1.3). Conclusion Impaired renal function is strongly associated with worse outcome in patients with SCAD and known coronary anatomy. The associations were independent of traditional cardio vascular disease risk factors, comorbidities, coronary artery obstruction severity, and subsequent revascularization.

- Background We hypothesized that the transition from bare-metal stents (BMS) to newer generation drug-eluting stents (n-DES) in clinical practice may have reduced the risk also in patients with kidney dysfunction. Methods: Observational study in the national SWEDEHEART registry, that compared the 1-year risk of in-stent restenosis (RS) and stent thrombosis (ST) in all percutaneous coronary intervention treated patients(n = 92 994) during 2007-2013. Results: N-DES patients were younger than BMS, but had more often diabetes, previous myocardial infarction, previous revascularization and were more often treated with potent platelet inhibition. N-DES versus BMS, was associated with lower 1-year risk of RS in patients with estimated glomerular filtration rate (eGFR) >60 with a cumulative probability of 2.1% versus 5.3%, adjusted hazard ratio 0.30, 95% CI (0.27-0.34) and with eGFR 30-60: 3.0% versus 4.9%; hazard ratio 0.46 (0.36-0.60) but not in patients with eGFR <30: 8.1% versus 6.0%; hazard ratio 1.32 (0.71-2.45) (pinteraction = 0.009) as well as lower risk of ST for eGFR >60 and eGFR 30-60: 0.5% versus 0.9%; hazard ratio 0.52 (0.40-0.68) and 0.6% versus 1.3%; hazard ratio 0.54 (0.54-0.72) but not for eGFR <30; 2.1% versus 1.1%; hazard ratio 1.49 (0.56-3.98) (p(interaction)= 0.027). Conclusion: N-DES is associated with lower 1-year risk of in-stent restenosis and stent thrombosis in patients with normal or moderately reduced kidney function but not in patients with severe kidney dysfunction, where stenting is associated with worse outcomes regardless of stent type.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Cardiac troponin (cTn) is important for risk assessment in patients with suspected acute coronary syndrome (ACS). cTn concentrations may, however, be affected by renal dysfunction, and the clinical importance of this interrelation is not well established. We investigated the association between cTnT and cTnI (measured with conventional assays and a more sensitive assay) with the estimated glomerular filtration rate (eGFR) and also assessed the ability of cTn to predict the 1-year all-cause mortality. METHODS: This retrospective registry-based study used data from 309454 admissions to Swedish coronary care units. cTn associations with eGFR and mortality were assessed using different regression models and by calculating multivariable-adjusted c-statistics. RESULTS: cTnT concentrations exhibited stronger associations with eGFR than cTnI concentrations (conventional cTnT assay: beta = -0.113; more sensitive cTnT assay: beta = -0.186; pooled conventional cTnI assays: beta = -0.098). Overall, cTnT provided greater prognostic accuracy than cTnI. This was most evident in non-ACS patients with normal or mildly reduced eGFR when using the more sensitive assay. Despite higher mortality rates, no consistent increases in the c-statistics of cTn were seen with severely reduced eGFR irrespective of the presence of ACS or non-ACS. CONCLUSIONS: cTnT concentrations exhibited stronger associations with reduced eGFR than cTnI concentrations in patients admitted because of suspected ACS. cTnT, particularly when measured using the more sensitive assay, also tended to be a stronger prognosticator. However, the relative significance of the obtained results must be considered in the context of the severity of renal dysfunction and whether ACS is present.

- BACKGROUND There is no consensus whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) should be used for secondary prevention in all or in only high-risk patients after an acute myocardial infarction (AMI).OBJECTIVES This study sought to investigate whether ACEI/ARB treatment after AMI is associated with better outcomes across different risk profiles, including the entire spectrum of estimated glomerular filtration rates.METHODS This study evaluated discharge and continuous follow-up data on ACEI/ARB use among AMI survivors (2006 to 2009) included in a large Swedish registry. The association between ACEI/ARB treatment and outcomes (mortality, myocardial infarction, stroke, and acute kidney injury [AKI]) was studied using Cox proportional hazards models (intention-to-treat and as treated).RESULTS In total, 45,697 patients (71%) were treated with ACEI/ARB. The 3-year mortality was 19.8% (17.4% of ACEI/ARB users and 25.4% of nonusers). In adjusted analysis, significantly better survival was observed for patients treated with ACEI/ARB (3-year hazard ratio: 0.80; 95% confidence interval: 0.77 to 0.83). The survival benefit was consistent through all kidney function strata, including dialysis patients. Overall, those treated with ACEI/ARB also had lower 3-year risk for myocardial infarction (hazard ratio: 0.91; 95% confidence interval: 0.87 to 0.95), whereas treatment had no significant effect on stroke risk. The crude risk for AKI was in general low (2.5% and 2.0% for treated and nontreated, respectively) and similar across estimated glomerular filtration rate categories but was significantly higher with ACEI/ARB treatment. However, the composite outcome of AKI and mortality favored ACEI/ARB treatment.CONCLUSIONS Treatment with ACEI/ARB after AMI was associated with improved long-term survival, regardless of underlying renal function, and was accompanied by low rates of adverse renal events.

- AIM: To develop a simple risk-score model for predicting in-hospital cardiac arrest (CA) among patients hospitalized with suspected non-ST elevation acute coronary syndrome (NSTE-ACS).METHODS: Using the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART), we identified patients (n=242 303) admitted with suspected NSTE-ACS between 2008 and 2014. Logistic regression was used to assess the association between 26 candidate variables and in-hospital CA. A risk-score model was developed and validated using a temporal cohort (n=126 073) comprising patients from SWEDEHEART between 2005 and 2007 and an external cohort (n=276 109) comprising patients from the Myocardial Ischaemia National Audit Project (MINAP) between 2008 and 2013.RESULTS: The incidence of in-hospital CA for NSTE-ACS and non-ACS was lower in the SWEDEHEART-derivation cohort than in MINAP (1.3% and 0.5% vs. 2.3% and 2.3%). A seven point, five variable risk score (age ≥60 years (1 point), ST-T abnormalities (2 points), Killip Class >1 (1 point), heart rate <50 or ≥100bpm (1 point), and systolic blood pressure <100mmHg (2 points) was developed. Model discrimination was good in the derivation cohort (c-statistic 0.72) and temporal validation cohort (c-statistic 0.74), and calibration was reasonable with a tendency towards overestimation of risk with a higher sum of score points. External validation showed moderate discrimination (c-statistic 0.65) and calibration showed a general underestimation of predicted risk.CONCLUSIONS: A simple points score containing five variables readily available on admission predicts in-hospital CA for patients with suspected NSTE-ACS.
