BACKGROUND Homocysteine is a risk factor for cardiovascular disease. We evaluated the efficacy of homocysteine-lowering treatment with B vitamins for secondary prevention in patients who had had an acute myocardial infarction. METHODS The trial included 3749 men and women who had had an acute myocardial infarction within seven days before randomization.(More)
AIMS A relation between left ventricular hypertrophy and parathyroid hormone (PTH) has been described in patients with end stage renal disease and secondary hyperparathyroidism. In vitro studies indicate a hypertrophic effect of PTH on cardiomyocytes. The purpose of this study was to examine the relation between PTH and left ventricular hypertrophy in a(More)
We wanted to determine the risk of non-vertebral fracture associated with type and duration of diabetes mellitus, adjusting for other known risk factors. This is a population-based 6-year follow-up of 27,159 subjects from the municipality of Tromsø, followed from 1994 until 2001. The age range was 25-98 years. Self-reported diabetes cases were validated by(More)
Population-based data on the prevalence of persistent postsurgical pain are scarce. This study aimed to assess the prevalence of persistent postsurgical pain in a general population and to describe associated physical, social, and psychological factors, including symptoms of nerve injury and sensitization. A cross-sectional survey was performed in northern(More)
The role of testosterone in the development of cardiovascular disease is controversial. Recent observational studies, however, suggest a protective role of normal endogenous testosterone levels in the development of atherosclerosis. In a cohort from the Tromsø study, 1,101 men had both hormone-levels measured and the right carotid artery examined by(More)
CONTEXT Overt hypo- and hyperthyroidism are associated with cardiac disease, whereas this relation is more uncertain regarding subclinical thyroid dysfunction. OBJECTIVE The objective was to assess the relation between serum TSH level and cardiac function. DESIGN We conducted a cross-sectional epidemiological study and a nested case-control study. (More)
Serum calcium measured in 27,158 subjects in 1994 and the calcium-sensing receptor polymorphism rs17251221 genotyped in 9,404 subjects were related to cardiovascular risk factors, incident myocardial infarction (MI), type 2 diabetes (T2DM), cancer and death during follow-up until 2008-2010. In a Cox regression model with adjustment for age, gender, smoking(More)
Animal and human studies have shown an association between serum 25-hydroxyvitamin D (25(OH)D) level and insulin secretion and sensitivity. Accordingly, an association between 25(OH)D and glycated haemoglobin (HbA(1c)) is to be expected, and this was tested for in the present study. The Tromsø Study is a longitudinal population-based study initiated in(More)
OBJECTIVE To study the impact of endogenous testosterone levels in community-dwelling men on later risk for myocardial infarction (MI) and all-cause, cardiovascular disease (CVD), and ischemic heart disease (IHD) mortality. DESIGN Population-based prospective cohort study. METHODS For the analyses, we used a cohort of 1568 randomly selected men, with(More)
OBJECTIVE Low serum 25(OH)D levels are associated with cardiovascular risk factors, and also predict future myocardial infarction (MI), type 2 diabetes (T2DM), cancer and all-cause mortality. Recently several single nucleotide polymorphisms (SNPs) associated with serum 25-hydroxyvitamin D (25(OH)D) level have been identified. If these relations are causal(More)
