Aim: Data regarding the prognostic value of peripheral endothelial function testing in patients with cardiovascular disease are conflicting. Peripheral arterial tonometry(PAT) is increasingly used to measure the peripheral endothelial function. The prognostic value of this method has not been investigated thus far in patients with cardiovascular d...

Background: Millions of people have now been vaccinated against SARS-CoV-2. However, it is still unclear which antibody levels provide protection against mortality. It is further unknown whether measuring antibody concentrations on hospital admission allows identifying patients with a high risk of mortality. Objectives: To evaluate whether anti-...

Objectives To evaluate the long-term performance of the SonRtip atrial lead. Background To optimize atrioventricular and interventricular timing and thereby potentially improving cardiac resynchronization therapy (CRT) responder rates, a lead integrated technology and a cardioverter/defibrillator-based algorithm measuring peak endocardial accelera...

Background: Women undergoing coronary angiography (CA) due to chest pain are more likely to present with less extensive coronary artery disease (CAD) than men, which might be attributed to different effects of cardiovascular risk factors on coronary atherogenesis between sexes. The aim of the present study was to evaluate sex differences in indepe...

Endothelial dysfunction represents an early step in atherogenesis, and can be non-invasively measured in peripheral vessels. The most common used technique to assess peripheral endothelial function is the ultrasound-based measurement of flow mediated di-ation (FMD) of the brachial artery. However, this method lacks in standardization and has a well...

Background: Weather conditions influence symptoms in chronic stable coronary artery disease (CAD). Whether the ongoing climate change, with continuous and rapid temperature increases, also has an impact on the incidence and outcome of non-ST elevation (NSTEMI) and ST elevation (STEMI) myocardial infarctions referred for acute coronary angiography...

Endothelial dysfunction represents an early step in atherogenesis, and can be non-invasively measured in peripheral vessels. The most common used technique to assess peripheral endothelial function is the ultrasound-based measurement of flow mediated dilation (FMD) of the brachial artery. However, this method lacks in standardization and has a well...

Post-cardiac catheterization femoral artery hemostasis can be accomplished with several mechanisms, including the FemoSeal® hemostasis device which has been designed and approved for closure of 6 French (F) arterial puncture sites. The aim of this study was to investigate whether the FemoSeal® vascular closure device can effectively and safely seal...

Shift working is related to increased cardiovascular morbidity. Peripheral endothelial dysfunction, an inherent feature of early atherosclerosis, has been suggested as a surrogate marker of cardiovascular risk. Whether shift working is associated with peripheral endothelial dysfunction has not been investigated to date. A total of 48 male shift wor...

2008 new guidelines for the management of patients with ST-elevation myocardial infarction were published by the European Society of Cardiology. For daily clinical practice, changes in recommendations concerning the preferred revascularization therapy according to different time delays are of great interest. This review focuses on possible implicat...

We read with great interest the comments of Avanzas et al. on our recent article. In acute coronary syndromes, inflammatory markers such as neopterin - a macrophage-specific activation marker - reflect plaque instability, i.e. disease activity. In stable coronary artery disease (CAD) patients, inflammatory markers such as C-reactive protein (CRP) n...

The aim of the prospective, randomized, placebo-controlled Tyrolean Aortic Stenosis Study (TASS) was to characterize the natural history and risk factors and their possible modulation by new-onset atorvastatin treatment (20 mg/day vs placebo) in patients with asymptomatic calcified aortic stenosis. Forty-seven patients without previous lipid-loweri...

Whether or not primary percutaneous coronary intervention (P-PCI) is equally effective and safe in women and men in a real world setting is still a matter of debate. The aim of this study was to evaluate the effect of gender on in-hospital outcome after P-PCI for ST-elevation myocardial infarction (STEMI) in a prospective national registry. This re...

Macrophages and pro-inflammatory CD3+CD4+CD28- T lymphocytes are involved in atherosclerotic plaque destabilization. Whether neopterin, a macrophage-specific activation-marker, and circulating CD3+CD4+CD28- cells are also related to the severity and extent of coronary artery disease (CAD) in stable patients is still unclear. Coronary angiograms of...

Although high-density lipoprotein cholesterol (HDL-C) and C-reactive protein (CRP) are well-established predictors for future cardiovascular events, little information is available regarding their correlation with the prevalence and severity of angiographically evaluated coronary artery disease (CAD). Five thousand six hundred forty-one consecutive...

Recent studies have demonstrated a high sensitivity (S) of 16-multidetector computed tomography (16-MDCT) for the detection of significant coronary artery stenoses. Whether these results are applicable to clinical practice is unclear. Therefore, the aim of the present study was to compare 16-MDCT angiography with conventional coronary angiography (...

Endothelial dysfunction, detectable by an impaired flow-mediated vasodilation (FMD) of the brachial artery, has been shown to be associated with increased levels of circulating proinflammatory markers. Therapeutic interventions such as lipid-lowering with statins increase FMD and decrease inflammatory markers, like soluble (s) E-selectin, soluble i...

The aim of this pilot study was to test the prognostic value of serial measurements of peripheral endothelial function, assessed by brachial artery flow-mediated dilation (FMD), in patients with angiographically proven coronary artery disease. In 68 patients, FMD was measured on the day after coronary angiography and again after a mean of 14 +/- 12...

Coronary atherosclerosis includes an activation of circulating T lymphocytes. Statins exert anti-inflammatory effects beyond lipid lowering. Whether these properties influence systemic T lymphocytes is unclear. To investigate the effect of atorvastatin on circulating T-lymphocyte subsets producing proinflammatory and anti-inflammatory cytokines (in...

We sought to examine the prognostic value of brachial artery (BA) flow-mediated vasodilation (FMD) and intima-media thickness (IMT) in patients admitted for invasive evaluation of chest pain. Both FMD and IMT of the BA have been associated with coronary risk factors and the presence of coronary artery disease (CAD). Recent studies on the prognostic...

The aim of this study was to determine whether sonographically assessed intimal (echodense, ED) or medial (echolucent, EL) thickening of the brachial artery is associated with coronary artery disease (CAD) and/or arterial hypertension (HT). In 201 patients the ED and EL wall components, as well as the total wall thickness of the brachial artery, we...

All stages of atherosclerotic plaques are characterized by an inflammatory component, in which T lymphocytes and macrophages orchestrate lesion progression and destabilization by releasing cytokines (e.g., interferon-gamma, tumor necrosis factor-alpha, tissue factor). At the extreme end of this process plaque rupture occurs, which may manifest clin...
