BACKGROUND Growth differentiation factor-15 (GDF-15), a stress-responsive transforming growth factor-ß-related cytokine, is elevated and independently related to an adverse prognosis in systolic heart failure. OBJECTIVE This study aimed to investigate plasma levels of GDF-15 in patients with preclinical diastolic dysfunction or heart failure with normal(More)
AIMS Left ventricular diastolic dysfunction is considered a precursor of diabetic cardiomyopathy, while diabetic cardiovascular autonomic neuropathy is associated with an increased risk of mortality. This study aimed to evaluate the association between left ventricular diastolic dysfunction and cardiovascular autonomic neuropathy, both diagnosed according(More)
BACKGROUND The Frank-Starling mechanism is one of the most important physiological principles for regulation of contractile performance. We therefore studied the question of whether this mechanism may be absent or attenuated in end-stage failing human left ventricular myocardium. METHODS AND RESULTS Different methodological approaches were used to analyze(More)
BACKGROUND Diabetes mellitus (DM) has reached epidemic proportions and is an important risk factor for heart failure (HF). Left ventricular diastolic dysfunction (LVDD) is recognized as the earliest manifestation of DM-induced LV dysfunction, but its pathophysiology remains incompletely understood. We sought to evaluate the relationship between(More)
OBJECTIVE Left ventricular diastolic dysfunction (LVDD) is considered a precursor of diabetic cardiomyopathy, while the metabolic syndrome (MetS) is associated with an increased risk of cardiovascular morbidity and mortality. This study aimed to evaluate the association between LVDD, MetS and glucose metabolism disturbances classified by oral glucose(More)
BACKGROUND Left ventricular diastolic dysfunction (LVDD) is considered a precursor of diabetic cardiomyopathy, while insulin resistance (IR) is a precursor of type 2 diabetes mellitus (T2DM) and independently predicts heart failure (HF). We assessed whether IR and abnormalities of the glucose metabolism are related to LVDD. METHODS We included 208(More)
BACKGROUND Increased muscle mass index of the left ventricle (LVMi) is an independent predictor for the development of symptoms in patients with asymptomatic aortic stenosis (AS). While the onset of clinical symptoms and left ventricular systolic dysfunction determines a poor prognosis, the standard echocardiographic evaluation of LV dysfunction, only based(More)
OBJECTIVE The development of left ventricular remodelling (LVR) after acute myocardial infarction (AMI) is a predictor of heart failure and mortality. The extracellular matrix (ECM) is highly susceptible to ischaemic injury. Laminin and collagen type VI (CVI) contribute to ECM formation in the infarct zone. To determine whether these markers can be detected(More)
It has been suggested that matrix-metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of metalloproteinases (TIMPs) play a major role in the regulation of myocardial remodeling. Myocardial extracellular matrix (ECM) is highly susceptible to ischemic injury in acute myocardial infarction (AMI).We measured serum levels of TIMP-1 in the early(More)
OBJECTIVE The development of diastolic dysfunction (DDF) is multifactorial. Possible mechanisms include metabolic disturbances, myocardial fibrosis, chronic inflammation and endothelial dysfunction. Recognizing early stages of DDF may help to identify patients at risk of developing symptomatic DDF. Therefore, biomarkers reflecting pathophysiological changes(More)
