Associations between life course socioeconomic position (SEP) and novel biological risk markers for coronary heart disease such as inflammatory markers are not well understood. Most studies demonstrate inverse associations of life course SEP with C-reactive protein (CRP), interleukin-6 (IL-6) and fibrinogen, however little is known about associations(More)
BACKGROUND After a change in Quebec's policy on drug coverage in August 1996, elderly patients' copayments for prescription drugs increased. We assessed the impact of this drug policy reform on prescribing patterns for essential cardiac medications, utilization of medical care and related health outcomes after acute myocardial infarction. METHODS Patients(More)
OBJECTIVES To compare the risk of death and recurrent congestive heart failure in elderly patients prescribed celecoxib, rofecoxib, or non-steroidal anti-inflammatory drugs (NSAIDs) and to determine whether there are class differences between celecoxib and rofecoxib. DESIGN Population based retrospective cohort study. SETTING Databases of hospital(More)
BACKGROUND Patients exposed to low-dose ionizing radiation from cardiac imaging and therapeutic procedures after acute myocardial infarction may be at increased risk of cancer. METHODS Using an administrative database, we selected a cohort of patients who had an acute myocardial infarction between April 1996 and March 2006 and no history of cancer. We(More)
BACKGROUND Hyperuricemia is associated with reduced survival among patients with heart failure (HF), but the effect of gout on HF outcomes is unknown. A recent randomized trial suggested that allopurinol may reduce adverse outcomes among patients with hyperuricemia and HF. Our objective was to determine whether gout and allopurinol use are associated with(More)
CONTEXT Hospital report cards are increasingly being implemented for quality improvement despite lack of strong evidence to support their use. OBJECTIVE To determine whether hospital report cards constructed using linked hospital and prescription administrative databases are effective for improving quality of care for acute myocardial infarction (AMI).

Cumulative exposure to socioeconomic disadvantage across the life course may be inversely associated with coronary heart disease (CHD); the mechanisms are not fully clear. An objective of this study was to determine whether cumulative life-course socioeconomic position (SEP) is associated with CHD incidence in a well-characterized US cohort that had(More)
Flow cytometry has been used to study the contents of macromolecular compounds and light-scatter parameters in batch and continuous cultures of a recombinant Escherichia coli strain that forms protein inclusion bodies. Changes in relative DNA and RNA contents and cell mass as estimated by forward-angle light scatter were detected and tightly correlated in(More)
OBJECTIVE Nonsteroidal antiinflammatory drugs (NSAIDs) as a class have been shown to increase the risk of congestive heart failure (CHF) compared with celecoxib. The magnitude of the risk for individual NSAIDs is not known. METHODS Using administrative databases, we performed a nested case-control study in a population-based cohort of patients ages >or=66(More)
BACKGROUND Although it has been well documented that aspirin, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, and lipid-lowering drugs are under-prescribed for patients with acute myocardial infarction (Am Heart J 2003;145:438-44.), few studies have examined dosage and long-term compliance and persistence patterns for the use of these drugs(More)
