Left atrial tissue samples from patients with AF or sinus rhythm SR with or without metoprolol mean daily dose: Transverse and longitudinal conduction velocities were determined by 64 multi-electrode mapping. Cxexpression in AF was significantly higher in patients receiving metoprolol, while Cx40 expression was unaffected by metoprolol treatment. Functionally, in AF patients, transverse conduction velocity in atrial samples was significantly enhanced and this change was also significantly antagonized by metoprolol. AF induced enhanced lateral expression of Cx43 and Cx40 together with enhanced transverse conduction velocity in left atrial tissue.

The discrepancies between the observed levels of expression among these studies may be related to the various patient populations with varying percentages of patients suffering from mitral valve disease MVD or coronary heart disease CHD as the reason for the cardiac surgery, so that a sample can be obtained, and the question whether right metoprolol plm left atrial tissue has been investigated, and whether this was from the free wall or from the appendage, metoprolol plm.

Metoprolol is used alone or together with other medicines to treat high blood pressure hypertension. High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks or strokes. These problems may be less likely to occur if blood pressure is controlled. Metoprolol is also used to treat severe chest pain angina and lowers the risk of repeated heart attacks. It is given to people who have already had a heart attack. In addition, metoprolol is used to treat patients with heart failure.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Your dose may need to be changed several times in order to find out what works best for you. In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of food you eat, especially foods high in sodium salt.

Understanding sex-based differences. Alterations in localization of Cx43 and conduction changes were both antagonized by metoprolol, showing that pharmacological modulation of gap junction remodelling seems, in principle, possible. Figure 6. Changes in connexin expression and the atrial fibrillation substarate in congestive heart failure. Regarding the expression of Cx43 in AF in humans, there is some controversy whether Cx43 is up-regulated as seen by Yan et al. Federal government websites often end in. Eur Heart J 28 , — However, it should be mentioned that this analysis is only possible if the specimen are large enough, and that other factors like fibrosis also contribute to the changes in activation pattern, as shown in a dog model of congestive heart failure-associated AF Burstein et al. Compr Physiol 5 , — Immunoblots were exposed to X-ray film Eastman Kodak Co. This finding may open new approaches to the development of anti-arrythmic drugs. Indeed, modulating autonomic function to reduce innervation or sympathetic activity has shown useful for AF control reviewed in Chen et al. Regarding Cx40 distribution, there were no significant, changes in Cx40 expression at the cell poles Figure 5A , while we also found significantly enhanced expression of Cx40 at the sides of the cells in AF Figure 5B. Prevention of atrial fibrillation onset by beta-blocker treatment in heart failure: a meta-analysis.

The GAPDH value was used as an adjusting factor to assure that the same amount of cellular proteins in each patient was determined. Sympathetic activity plays an important role in modulation of cardiac rhythm. Figure 7. Thus, this is — to the best of our knowledge — the first description that the disturbance of the intracellular distribution pattern of Cx43 and Cx40 in AF is accompanied by enhanced transverse conduction velocity, and that enhanced V T and Cx43 remodelling are — at least partially — normalized in AF patients receiving metoprolol. If not stated differently, total connexin phosphorylated and non-phosphorylated was used for calculation. Expression of connexins 40 and 43 in human left atrium in atrial fibrillation of different aetiology. This investigation conformed to the principles outlined in the Declaration of Helsinki. Methods All patients gave informed written consent and the study was approved by the institutional ethical committee. Calcium cycling and signaling in cardiac myocytes. Fibrosis of collagen I and remodeling of connexin 43 in atrial myocardium of patients with atrial fibrillation. E-mail: ed. Temporal relations of atrial fibrillation and congestive heart failure and their joint influence on mortality: the Framingham study. Cardiomyocyte hypertrophy and increased fibrosis are hallmarks of cardiovascular disease and both aspects of remodeling are associated with arrhythmias.
