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.

These approaches have provided original insight into the regulation of cardiac excitation and contraction in health and disease metoprolol plm profound implications for therapy Surdo et al. Integrating these data from the sub-cellular, tissue, and multi-organ levels could accelerate our understanding of the complex network of pathways involved, predict mechanisms underlying the interaction between adrenergic activation and the functional cardiac substrate, metoprolol plm, and facilitate identification and specific targeting of arrhythmia provoking conditions by autonomic drugs.

It also is used to treat chronic long-term angina chest pain. Metoprolol is also used to improve survival after a heart attack. Metoprolol also is used in combination with other medications to treat heart failure. Metoprolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems.

Is there a role for remodelled connexins in AF? Eur J Heart Fail 20 , — Both connexins are involved in AF remodelling and it would be most interesting to find other drugs, which affect both connexins. Cxexpression in AF was significantly higher in patients receiving metoprolol, while Cx40 expression was unaffected by metoprolol treatment. Morphology of the intrinsic cardiac nervous system in the dog: a whole-mount study employing histochemical staining with acetylcholinesterase. Biophys J. Regarding Cx40, the finding of enhanced Cx40 expression and lateralization in AF in our patients is in good agreement with some other studies Dupont et al. That means that the finding of Cx43 lateralization and changes in anisotropy and its improvement by metoprolol therapy is limited to patients suffering from AF associated with MVD mainly mitral valve regurgitation in the absence of heart failure. Compr Physiol 5 , — Circ Res 91 , — This investigation conformed to the principles outlined in the Declaration of Helsinki.

Metoprolol is used alone or together with other medicines to treat high blood pressure hypertension.

Nature , — Our own data also showed that AF enhanced collagen-I expression, but that this was not affected by metoprolol. Ann Anat , — For suppression of the autofluorescence of the connective tissue in the atria, we incubated the slides after immunostaining with 0. Abstract Sympathetic activity plays an important role in modulation of cardiac rhythm. The main longitudinal fibre orientation is indicated by a light yellow arrow. PLoS One 9 , e Copy Download. Lancet 2 , 57— Early afterdepolarizations and cardiac arrhythmias. An action potential was elicited in the tissue with a rectangular pulse indicated at the site within the electrode matrix and propagated in longitudinal and transverse directions as shown by the arrows.
