Objectives: To compare management of patients with acute non-ST segment elevation myocardial infarction (NSTEMI) in three developed countries with national ongoing registries., Background: Results from clinical trials suggest significant variation in care across the world. However, international comparisons in "real world" registries are limited., Methods: We compared the use of in-hospital procedures and discharge medications for patients admitted with NSTEMI from 2007 to 2010 using the unselective MINAP/NICOR [England and Wales (UK); n=137,009], the unselective SWEDEHEART/RIKS-HIA (Sweden; n=45,069), and the selective ACTION Registry-GWTG/NCDR [United States (US); n=147,438] clinical registries., Results: Patients enrolled among the three registries were generally similar except those in the US who were younger but had higher rates of smoking, diabetes, hypertension, prior heart failure, and prior MI than in Sweden or in UK. Angiography and percutaneous coronary intervention (PCI) were performed more often in the US (76% and 44%) and Sweden (65% and 42%) relative to the UK (32% and 22%). Discharge betablockers were also prescribed more often in the US (89%) and Sweden (89%) than in the UK (76%). In contrast, discharge statins, angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB), and dual antiplatelet agents (among those not receiving PCI) were higher in the UK (92%, 79%, and 71%) than in the US (85%, 65%, 41%) and Sweden (81%, 69%, and 49%)., Conclusions: The care for patients with NSTEMI differed substantially among the three countries. These differences in care among countries provide an opportunity for future comparative effectiveness research as well as identify opportunities for global quality improvement., (Copyright © 2014.

Despite scientific evidence that secondary prevention medical therapies reduce mortality in patients with established coronary artery disease, these therapies continue to be underutilized in patients receiving conventional care. To address this issue, a Cardiac Hospital Atherosclerosis Management Program (CHAMP) focused on initiation of aspirin, cholesterol-lowering medication (hydroxymethylglutaryl coenzyme A [HMG CoA] reductase inhibitor titrated to achieve low-density lipoprotein [LDL] cholesterol < or =100 mg/dl), beta blocker, and angiotensin-converting enzyme (ACE) inhibitor therapy in conjunction with diet and exercise counseling before hospital discharge in patients with established coronary artery disease. Treatment rates and clinical outcome were compared in patients discharged after myocardial infarction in the 2-year period before (1992 to 1993) and the 2-year period after (1994 to 1995) CHAMP was implemented. In the pre- and post-CHAMP patient groups, aspirin use at discharge improved from 68% to 92% (p <0.01), beta blocker use improved from 12% to 62% (p <0.01), ACE inhibitor use increased from 6% to 58% (p <0.01), and statin use increased from 6% to 86% (p <0.01). This increased use of treatment persisted during subsequent follow-up. There was also a significant increase in patients achieving a LDL cholesterol < or =100 mg/dl (6% vs 58%, p <0.001) and a reduction in recurrent myocardial infarction and 1-year mortality. Compared with conventional guidelines and care, CHAMP was associated with a significant increase in use of medications that have been previously demonstrated to reduce mortality; more patients achieved an LDL cholesterol < or =100 mg/dl, and there were improved clinical outcomes in patients after hospitalization for acute myocardial infarction.

Background: The present study aimed to assess use of lipid-lowering medication at discharge in a current national sample of patients hospitalized with acute myocardial infarction and to evaluate factors associated with prescribing patterns., Methods and Results: Demographic, procedural, and discharge medication data were collected from 138 001 patients with acute myocardial infarction discharged from 1470 US hospitals participating in the National Registry of Myocardial Infarction 3 from July 1998 to June 1999. Lipid-lowering medications were part of the discharge regimen in 31. 7%. Among patients with prior history of CAD, revascularization, or diabetes, less than one half of the patients were discharged on treatment. In multivariate analysis, factors independently related to lipid-lowering use included history of hypercholesterolemia (odds ratio [OR] 4.93; 95% CI 4.79 to 5.07), cardiac catheterization during hospitalization (OR 1.29; 95% CI 1.24 to 1.34), care provided at a teaching hospital, (OR 1.26; 95% CI 1.22 to 1.32), use of ss-blocker (OR 1.43; 95% CI 1.39 to 1.48), and smoking cessation counseling (OR 1.51; 95% CI 1.44 to 1.59). Lipid-lowering medications were given less often to patients who were older (65 to 74 versus <55 years of age; OR 0.82; 95% CI 0.78 to 0.86), those with a history of hypertension (OR 0.92; 95% CI 0.89 to 0.95), and those undergoing coronary artery bypass graft surgery (OR 0.58; 95% CI 0.55 to 0.60)., Conclusions: Analysis of current practice patterns for the use of lipid-lowering medications in patients hospitalized with acute myocardial infarction reveals that a significant proportion of high-risk patients did not receive treatment at time of discharge.
