- Large real-world registry data are important for understanding the current use and outcomes of novel therapies. The aim of this study was to assess treatment patterns and outcomes in patients who underwent percutaneous coronary intervention (PCI) with prasugrel or clopidogrel. Consecutive patient data from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) for 2010 and 2011 were used. The study population consisted of all patients with acute coronary syndromes (ACS) and those without ACS who underwent PCI and were treated with prasugrel (with or without a clopidogrel loading dose) or solely with clopidogrel. Outcomes included were 30-day mortality and in-hospital bleeding. In 2010 and 2011, 23,994 patients were treated with clopidogrel during hospitalization for their first PCI during the study period, while 2,142 patients were treated with prasugrel. Prasugrel was mainly used in patients with ST-segment elevation myocardial infarction. Hemorrhagic risk factors such as older age, female gender, and previous stroke were more common in the clopidogrel-treated patients. However, Mehran bleeding risk scores were higher in prasugrel-treated patients. In the ACS group, lower mortality was observed in the prasugrel group compared with the clopidogrel group. Mortality was comparable in patients who underwent elective angiography and PCI. In-hospital bleeding was lower in prasugrel-treated patients. In conclusion, in this real world population of patients who underwent urgent or elective PCI, prasugrel was used mainly in patients with ACS, while it was avoided in patients with characteristics indicating increased bleeding risk. Mortality and bleeding rates were lower with prasugrel than clopidogrel, probably because of patient selection.

- The aim of this study was to evaluate the independent prognostic value of qualitative and quantitative admission electrocardiographic (ECG) analysis regarding long-term outcomes after non-ST-segment elevation acute coronary syndromes (NSTE-ACS). From the Fragmin and Fast Revascularization During Instability in Coronary Artery Disease (FRISC II), Invasive Versus Conservative Treatment in Unstable Coronary Syndromes (ICTUS), and Randomized Intervention Trial of Unstable Angina 3 (RITA-3) patient-pooled database, 5,420 patients with NSTE-ACS with qualitative ECG data, of whom 2,901 had quantitative data, were included in this analysis. The main outcome was 5-year cardiovascular death or myocardial infarction. Hazard ratios (HRs) were calculated with Cox regression models, and adjustments were made for established outcome predictors. The additional discriminative value was assessed with the category-less net reclassification improvement and integrated discrimination improvement indexes. In the 5,420 patients, the presence of ST-segment depression (≥1 mm; adjusted HR 1.43, 95% confidence interval [CI] 1.25 to 1.63) and left bundle branch block (adjusted HR 1.64, 95% CI 1.18 to 2.28) were independently associated with long-term cardiovascular death or myocardial infarction. Risk increases were short and long term. On quantitative ECG analysis, cumulative ST-segment depression (≥5 mm; adjusted HR 1.34, 95% CI 1.05 to 1.70), the presence of left bundle branch block (adjusted HR 2.15, 95% CI 1.36 to 3.40) or ≥6 leads with inverse T waves (adjusted HR 1.22, 95% CI 0.97 to 1.55) was independently associated with long-term outcomes. No interaction was observed with treatment strategy. No improvements in net reclassification improvement and integrated discrimination improvement were observed after the addition of quantitative characteristics to a model including qualitative characteristics. In conclusion, in the FRISC II, ICTUS, and RITA-3 NSTE-ACS patient-pooled data set, admission ECG characteristics provided long-term prognostic value for cardiovascular death or myocardial infarction. Quantitative ECG characteristics provided no incremental discrimination compared to qualitative data.

Tidskriftsartikel (refereegranskat)abstract
- The objective of this prospective cohort study was to describe real-life use of lipid-lowering drugs and low-density lipoprotein cholesterol (LDL-C) target-attainment rates 1 year after acute myocardial infarction (AMI). LDL-C was recorded at hospital admission for AMI and at follow-up at 2 and 12 months after AMI in 17,236 patients in the Swedish heart registry, SWEDEHEART, from 2004 through 2009. Lipid-lowering treatments were identified using the Swedish Prescribed Drug Register. More than 90% of patients received statins after ANT. Simvastatin <= 40 mg was used by 80% of patients at discharge and at 2 months and 68% at 1 year after AMI. Intensive statin therapy (LDL-C-lowering capacity >40%) was prescribed for 8.4%, 11.9%, and 12.2% at these time points, and combinations of statin/ezetimibe for 1.1%, 2.8%, and 5.0%, respectively. The LDL-C target of <2.5 mmol/L (97 mg/dl) was achieved in 74.5% of patients at 2 months and 72.3% at 12 months after AMI. Treatment was intensified for only 21.3% of patients with LDL-C above target at 2 months. In multivariate analysis, higher LDL-C levels at admission and at 2 months correlated to increased risk for under treatment at 12 months after AMI. In conclusion, statin treatment after AMI in Sweden has become standard, but titration to reach recommended LDL-C levels is still suboptimal. Strategies to further improve implementation of guidelines are needed. (C) 2014 Elsevier Inc. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to compare the prognoses of patients with ST-segment elevation myocardial infarction (STEMI) and those with non-ST-segment elevation myocardial infarction (NSTEMI) without obstructive coronary artery disease (CAD) and the risk associated with gender for future cardiovascular events. The study population was selected from 95,849 patients who underwent coronary angiography for myocardial infarction from 2005 to 2010 and registered in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Outcome analyses, including all-cause death, myocardial infarction, congestive heart failure, stroke, and revascularization, were performed in 2,268 patients with STEMI and 10,904 with NSTEMI without obstructive CAD (<50% stenosis). Hazard ratios and 95% confidence intervals comparing women with men were calculated for events, adjusting for cardiovascular risk factors and age. Nonobstructive CAD was found in 7% of patients with STEMI (6% men, 10% women) and in 17% of those with NSTEMI (11% men, 28% women). During a median follow-up of 2.6 years, 8% of patients with STEMI and 5% of those with NSTEMI died. Gender-associated differences in risk were observed in patients with NSTEMI, with adjusted hazard ratios lower in women than men for mortality (hazard ratio 0.90, 95% confidence interval 0.50 to 0.73) and congestive heart failure (hazard ratio 0.61, 95% confidence interval 0.52 to 0.72). In the 2 groups, women underwent less revascularization. In conclusion, nonobstructive CAD was more common in patients with NSTEMI than those with STEMI, as well as in women compared with men. Long-term mortality in patients with nonobstructive CAD was higher after STEMI than NSTEMI. The gender differences in outcomes suggest gender differences in the underlying pathogenesis of myocardial infarction without obstructive CAD.

Tidskriftsartikel (refereegranskat)abstract
- Increasing attention is being directed toward new lipid and lipoprotein biomarkers as risk factors for coronary artery disease, although limited information is available on the diagnostic accuracy of these new biomarkers for the identification of patients with coronary artery disease. In the present study, levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, lipoprotein-associated phospholipase A2 (Lp-PLA2), and oxidized LDL/HDL cholesterol were determined in 431 apparently healthy men and women without clinical evidence of coronary artery disease who were matched for age and gender with 490 men and women with coronary artery disease who participated in the Second Fragmin and Fast Revascularization During Instability in Coronary Artery Disease (FRISC-II) trial. Diagnostic accuracy was determined by receiver-operating characteristic curve analysis by measuring the area under the curve. The diagnostic accuracies of each lipid or lipoprotein biomarker (in descending order of area under the curve) were 0.867 for oxidized LDL/HDL cholesterol (95% confidence interval [CI] 0.844 to 0.890), 0.826 for oxidized LDL (95% CI 0.800 to 0.852), 0.775 for 1/HDL cholesterol (95% CI 0.745 to 0.805), 0.764 for total/HDL cholesterol (95% CI 0.733 to 0.795), 0.631 for triglycerides (95% CI 0.594 to 0.667), 0.597 for Lp-PLA2 (95% CI 0.558 to 0.615), 0.577 for LDL cholesterol (95% CI 0.539 to 0.615), and 0.520 for total cholesterol (95% CI 0.482 to 0.537). In conclusion, these findings indicate that the ratio of oxidized LDL to HDL cholesterol was a more potent biomarker for discriminating between subjects with and without coronary artery disease than traditionally measured lipids and lipoproteins and Lp-PLA2.

Gender Differences in Outcomes and Predictors of All-Cause Mortality After Percutaneous Coronary Intervention (Data from United Kingdom and Sweden)
- 2017
-

Tidskriftsartikel (refereegranskat)abstract
- To determine gender differences and predictors of all-cause mortality (30 days and 1 year) after percutaneous coronary intervention (PCI) in patients with stable angina pectoris and acute coronary syndrome (non ST-elevation myocardial infarction/unstable angina pectoris and ST-elevation myocardial infarction) in the British Cardiovascular Intervention Society (BCIS) and Swedish Coronary Angiography and Angioplasty Registry (SCAAR) data sets, an analysis of prospectively collected data from 2007 to 2011 was performed. In total, 458,261 patients (BCIS: n = 368,492 [25.9% women]; Sweden: n = 89,769 [27.2% women]) who underwent PCI were included in this analysis. Using multiple regression analysis, in the BCIS registry, female gender was an independent predictor of all-cause mortality at 30 days (odds ratio [OR] 1.15, 95% CI 1.10 to 1.22, p <0.0001) and at 1 year (OR 1.08, 95% CI 1.04 to 1.12, p <0.0001) after PCI for all patients. Likewise, in the SCAAR registry, female gender was an independent predictor of all-cause mortality at 30 days (OR 1.15, 95% CI 1.05 to 1.26, p = 0.002) and 1 year (OR 1.09, 95% CI 1.03 to 1.17, p = 0.006) after PCI for all patients. In both data sets, there was no statistically significant interaction between age and gender for all-cause mortality at 30 days (BCIS, p = 0.59; SCAAR, p = 0.40) and at 1 year (BCIS, p = 0.11; SCAAR, p = 0.83). In conclusion, despite advances in care, women compared with men continue to experience higher all cause mortality after PCI for coronary artery disease. The patient's age at the time of PCI remains a strong predictive factor of mortality in this population. Strategies and further research are warranted to better address the management of coronary artery disease in women with possibly earlier diagnosis and more tailored treatments.
