Hot Topics: Potentiating effect of inflammation and hyperglycemia in cardiovascular risk prediction

In elderly men with high risk of atherosclerosis, IL-18 was a strong predictor of cardiovascular events after 3 years, but only in subjects with the metabolic syndrome. There was an interaction between elevated fasting glucose and IL-18, and a stepwise increase in the predictive power of IL-18 by quartiles of fasting glucose. Elevated fasting glucose also increased the predictive power of IL-6 and CRP. These findings suggest a potentially synergistic effect of inflammation and hyperglycemia in cardiovascular risk prediction.

Hot Topics: The heart can compensate for loss of the calcium pump (SERCA2)

In the heart, the release of calcium from intracellular stores triggers muscle contraction. Lowered activity of the SERCA2 pump and reduced stores have been thought to cause heart failure. In a new mouse model it was surprising that despite almost complete absence of SERCA2 protein due to destruction of the Serca2 gene, heart function was maintained due to powerful compensatory mechanisms for a considerable length of time. Hence, future heart failure therapy may be directed towards stimulating the inherent capacity of the heart to compensate for loss of SERCA2 function. Read abstract here... Read editorial here...

Hot Topics: Very early oral glucose tolerance test after an acute STEMI has poor reproducibility and should not be recommended

In an observational cohort study of 224 STEMI patients, the prevalence of abnormal glucose regulation measued by an oral glucose tolerance test (OGTT) at three months was 24.9%, reduced from 46.9% when measured in-hospital. The observed reproducibility of the OGTTs performed in-hospital and at follow up was only 54 %. HbA1c, admission plasma glucose and fasting plasma glucose measured in-hospital seem to be useful as early markers of longstanding glucometabolic disturbance. Read more here...

Hot Topics: Chromogranin A is a strong predictor of mortality in patients with acute coronary syndromes

Chromogranin A (CgA), a protein produced throughout the neuroendocrine system, provides strong and independent information regarding long-term mortality and heart failure hospitalizations in patients with acute coronary syndromes, indicating a role for CgA in ACS risk stratification.

Hot Topics: LIGHT/PAR-2 synergy - a target for atherogenesis therapy?

The interaction between inflammatory cytokines and endothelial cells is a critical step in atherogenesis leading to endothelial dysfunction and inflammation. LIGHT/PAR-2-driven inflammation could be a pathogenic loop in atherogenesis, potentially representing a target for therapy in this disorder.

Hot Topics: No effect of drug therapy during cardiac arrest

Despite being widely advocated in resuscitation guidelines all over the world, intravenous drugs such as adrenaline/epinephrine, atropine and amiodarone have never been shown to increase long-term survival after cardiac arrest. This is the first randomized controlled trial to evaluate the effects of intravenous drug therapy vs. no drug therapy during cardiac arrest. This work received a Best Abstract Award at the Hot Topics Session during the Resuscitation Science Symposium at the AHA Scientific Sessions 2008.

Hot Topics: FX06 - protection from reperfusion injury

FX06, a fibrin-derived peptide, may reduce myocardial necrosis associated with successfully reperfused acute ST-segment elevation myocardial infarction (STEMI), according to results from the FX06 In Reperfusion (FIRE) trial. The FIRE trial showed only modest trends in favor of FX06, but could suggest possible protection from reperfusion injury.

Hot Topics: Fractalkine

Inflammatory processes mediated by cytokines are involved in the pathogenesis of heart failure. This study in mice identifies altered expression of 14 cytokines never previously associated with heart failure. Most pronounced was the up-regulation of fractalkine (CX3CL1) expression. Enhanced amounts of CX3CL1 were also found in human HF, both systemically and within the myocardium. In vitro experiments suggest that CX3CL1 may be involved in myocardial remodeling and reduction of myocardial contractile function. Read more in J Mol Cell Cardiol

Hot Topics: OPG - a new heart failure marker

Osteoprotegerin (OPG) is a member of the tumor necrosis factor receptor superfamily with pleiotropic effects on bone metabolism, endocrine function and the immune system. Myocardial expression and circulating levels of OPG are increased in heart failure. These studies demonstrate for the first time that (1) OPG levels on admission are predictive of mortality and heart failure development across the spectrum of acute coronary syndromes, and (2) OPG levels are independently and inversely related to left ventricular systolic function in the general population.

Hot Topics: G protein-coupled receptor kinases

G protein-coupled receptor kinases (GRK) are nodal regulators of myocardial G protein-coupled receptors. This study is the first to investigate the cardiovascular phenotype of endogenous cardiac GRK3, one of four expressed myocardial GRKs. Transgenic mice with a cardiac myocyte targeted inhibition of GRK3 display a hypertensive phenotype, intolerance for increased preload pressures and increased alpha-adrenergic receptor responsiveness.

Hot Topics: Rosuvastatins

The first statin trial in heart failure patients does not concur with previous statin trials in non-heart failure patients. This study shows that Rosuvastatin does not reduce the primary outcome or the number of deaths from any cause in older patients with systolic heart failure, but do reduce the number of cardiovascular hospitalizations. Rosuvastatin effectively reduced LDL and CRP and was well tolerated in this fragile patient population.
