BACKGROUND The natural history, management, and outcome of takotsubo (stress) cardiomyopathy are incompletely understood. METHODS The International Takotsubo Registry, a consortium of 26 centers in Europe and the United States, was established to investigate clinical features, prognostic predictors, and outcome of takotsubo cardiomyopathy. Patients were(More)
CONTEXT AND OBJECTIVE A growing body of evidence suggests that vitamin D deficiency may adversely affect the cardiovascular system. Therefore, we thought to prospectively assess the association between serum 25-hydroxyvitamin D, the most commonly used index of vitamin D status, and incident coronary heart disease. DESIGN, SETTING, AND PATIENTS We measured(More)
BACKGROUND For evaluation of patients with chest pain and suspected acute coronary syndrome (ACS), consensus guidelines recommend use of a cardiac troponin cut point that corresponds to the 99 th percentile of a healthy population. Most conventional troponin methods lack sufficient precision at this low level. METHODS AND RESULTS In a cross-sectional(More)
BACKGROUND Among the numerous emerging biomarkers, high-sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) have received widespread interest, and a large database has been accumulated on their potential role as predictors of cardiovascular risk. The concentrations of inflammatory biomarkers, however, are influenced, among other things, by(More)
BACKGROUND Chronic kidney disease (CKD) represents a global public health problem. Few data exist in the elderly. The objective of the current study is to estimate the prevalence of CKD by means of various established and new equations and to identify the main determinants of CKD in elderly. METHODS The ActiFE Ulm (Activity and Function in the Elderly in(More)
Risk prediction for type 2 diabetes (T2D) and cardiovascular disease (CVD) remains suboptimal even after the introduction of global risk assessment by various scores. This has prompted the search for additional biomarkers. A variety of blood biomarkers representing various pathophysiological pathways of insulin resistance and atherosclerosis, as well as(More)
BACKGROUND This study compares inflammation-related biomarkers with established cardiometabolic risk factors in the prediction of incident type 2 diabetes and incident coronary events in a prospective case-cohort study within the population-based MONICA/KORA Augsburg cohort. METHODS AND FINDINGS Analyses for type 2 diabetes are based on 436 individuals(More)
BACKGROUND Oxidative stress plays a critical role in the initiation and progression of atherosclerosis. Oxidized LDL (oxLDL) is a marker of oxidative stress. We prospectively investigated whether increased serum oxLDL concentrations are associated with incident coronary heart disease (CHD). METHODS We conducted a prospective population-based case-cohort(More)
IMPORTANCE Rapid and accurate diagnosis of acute myocardial infarction (AMI) currently constitutes an unmet need. OBJECTIVE To test a 1-hour diagnostic algorithm to diagnose AMI using a high-sensitivity troponin I assay with a new cutoff level of 6 ng/L. DESIGN, SETTING, AND PARTICIPANTS The Biomarkers in Acute Cardiac Care study is a prospective study(More)
Many disorders are associated with altered serum protein concentrations, including malnutrition, cancer, and cardiovascular, kidney, and inflammatory diseases. Although these protein concentrations are highly heritable, relatively little is known about their underlying genetic determinants. Through transethnic meta-analysis of European-ancestry and Japanese(More)
