Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris
2011
Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris Recent data indicate that the serum level of neopterin, a marker of inflammation and immune modulator secreted by monocytes/macrophages, is elevated in patients with acute coronary syndrome (ACS) and seems to be a prognostic marker for major cardiovascular events. Soluble cellular adhesion molecules (sCAMs) and myeloperoxidase (MPO) levels are also related to ACS. The aim of the present study was to evaluate differences in serum levels of neopterin, sCAMs and MPO between coronary artery disease and metabolic syndrome (CAD-MetS) patients with stable and unstable angina pectoris (SA…
Hyperuricaemia and gout in cardiovascular, metabolic and kidney disease
2020
During the last century, there has been an increasing prevalence of hyperuricaemia noted in many populations. While uric acid is usually discussed in the context of gout, hyperuricaemia is also associated with hypertension, chronic kidney disease, hypertriglyceridaemia, obesity, atherosclerotic heart disease, metabolic syndrome, and type 2 diabetes. Here we review the connection between hyperuricaemia and cardiovascular, kidney and metabolic diseases. Contrary to the popular view that uric acid is an inert metabolite of purine metabolism, recent studies suggest serum uric acid may have a variety of pro-inflammatory, pro-oxidative and vasoconstrictive actions that may contribute to cardiomet…
Disturbed Lipid Metabolism in Diabetic Patients with Manifest Coronary Artery Disease Is Associated with Enhanced Inflammation
2021
Background: Diabetic vasculopathy plays an important role in the pathophysiology of coronary artery disease (CAD) with oxidative stress as a strong mediator. This study aims to elucidate the underlying pathomechanisms of diabetic cardiac vasculopathy leading to coronary disease with an emphasis on the role of oxidative stress. Therefore, novel insights into antioxidant pathways might contribute to new strategies in the treatment and prevention of diabetic CAD. Methods: In 20 patients with insulin-dependent or non-insulin dependent diabetes mellitus (IDDM/NIDDM) and 39 non-diabetic (CTR) patients, myocardial markers of oxidative stress, vasoactive proteins, endothelial nitric oxide synthase …
A coronary right fistula canalized in a small accessory right atrial chamber.
2007
The coronary artery fistulas are rare congenital anomalies with a very low incidence. These can be symptomatic or asymptomatic because the hemodynamic consequences of the fistula vary and depend on the shunt dimensions. Discordant opinions instead are present in the literature for the defect closing in asymptomatic patients. Here, we describe a patient affected by a coronary right fistula canalized in a small accessory right atrial chamber. During follow-up, we observed a progressive dilatation of the right coronary artery (maximum diameter 10.3 mm) with hemodynamic overload of the right sections.
Non-Hemodynamic Effects of Organic Nitrates and the Distinctive Characteristics of Pentaerithrityl Tetranitrate
2009
Organic nitrates are among the oldest and yet most commonly employed drugs in the long-term therapy of coronary artery disease and congestive heart failure. While they have long been used in clinical practice, our understanding of their mechanism of action and side effects remains incomplete. For instance, recent findings provide evidence of previously unanticipated, non-hemodynamic properties that include potentially beneficial mechanisms (such as the induction of a protective phenotype that mimics ischemic preconditioning), but also toxic effects (such as endothelial and autonomic dysfunction, rebound angina, tolerance). To date, the most commonly employed organic nitrates are isosorbide …
Non Invasive Imaging of Myocardial Infarction with Computed Tomography and Magnetic Resonance
2012
Myocardial infarction is a major cause of death and disability worldwide. Myocardial infarction may represent a major catastrophic event leading to severe hemodynamic failure or sudden death or it may occur repeatedly in patients with established heart disease. In this context, the role of imaging techniques may become useful for the understanding of the determinants in a preclinical setting before acute coronary events, and for an accurate and correct diagnosis of myocardial infarction. Three-dimensional noninvasive imaging techniques, such as Cardiac CT (CCT) and Cardiac MR imaging (CMR) were widely developed in the last two decades. These imaging techniques may provide new insights into …
Carotid artery stenting outcomes in high-risk patients receiving best medical therapy: results from a single high-volume interventional cardiology pr…
2016
Kontext: Implantace stentů do karotických tepen (carotid artery stenting, CAS) se v soucasnosti ve velkem měřitku použiva v lecbě stenozy karotických tepen. Klinicke studie z posledni doby prokazaly nizkou incidenci přihod po CAS. Tato studie hodnoti 30denni a rocni výsledky pacientů lecených pro CAS intenzivni farmakoterapii na pracovisti provadějicim vysoke pocty perkutannich koronarnich intervenci rocně.Metoda: V obdobi od ledna 2011 do prosince 2013 byla CAS provedena celkem u 184 pacientů. Mimo protidestickove lecby byla provaděna i intenzivni antihypertenzni lecba spolu s vysoce intenzivni terapii statiny a lecbou zaměřenou na normalizaci srdecni frekvence. Pacienti byli stratifikovan…
Lipoprotein apheresis in Germany - Still more commonly indicated than implemented. How can patients in need access therapy?
2019
Abstract Background Although lipid-lowering drugs, especially statins, and recently also PCSK9 inhibitors can reduce LDL cholesterol (LDL-C) and decrease the risk for cardiovascular disease (CVD) including coronary artery disease (CAD) events most efficiently, only 5–10% of high-risk cardiovascular patients reach the target values recommended by international guidelines. In patients who cannot be treated adequately by drugs it is possible to reduce increased LDL-C and/or lipoprotein(a) (Lp(a)) values by the use of lipoprotein apheresis (LA) with the potential to decrease severe CVD events in the range of 70%->80%. Even in Germany, a country with well-established reimbursement guidelines for…
Lipoprotein apheresis for Lp(a)-hyperlipoproteinemia with progressive cardiovascular disease--Additional particular aspects of the Pro(a)LiFe multice…
2015
Lipoprotein apheresis (LA) can lower LDL-cholesterol and Lp(a) by 60%-70% and is the final escalating option in patients with hyperlipoproteinemias involving LDL or Lp(a) particles. Major therapeutic effect of LA is preventing cardiovascular events. In Germany since 2008 a reimbursement guideline has been implemented accepting to establish the indication for LA not only for familial or severe forms of hypercholesterolemia but also based on Lp(a)-hyperlipoproteinemia associated with a progressive course of cardiovascular disease, that persists despite effective treatment of other concomitant cardiovascular risk factors. The Pro(a)LiFe-study confirmed with a prospective multicenter design tha…
Response to Letter Regarding Article, “Different Calculations of Ankle Brachial Index and Their Impact on Cardiovascular Risk Prediction”
2009
We thank Jaquinandi et al for their interest in our publication. We want to stress that the patient population of the AtheroGene study is not comparable with the patient populations reported in the articles from Lee et al and Kreitner et al, which included only patients with known advanced peripheral arterial disease.1,2 The AtheroGene study includes primarily patients with coronary artery disease, no patient had rest pain or peripheral ulcers and only 52 patients (6.3%) had intermittent claudication.3 In addition, …
