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.

Metoprolol , sold under the brand name Lopressor among others, is a medication used to treat high blood pressure , angina , and a number of conditions involving an abnormally fast heart rate. Common side effects include trouble sleeping, feeling tired , feeling faint , and abdominal discomfort. Metoprolol was first made in , patented in , and approved for medical use in Metoprolol is used for a number of conditions, including hypertension , angina , acute myocardial infarction , supraventricular tachycardia , ventricular tachycardia , congestive heart failure , and prevention of migraine headaches. Off-label uses include supraventricular tachycardia and thyroid storm. Adverse effects, especially with higher doses, include dizziness, drowsiness, fatigue, diarrhea, unusual dreams, trouble sleeping, depression, and vision problems such as blurred vision or dry eyes. There may also be an impact on blood sugar levels and it can potentially mask signs of low blood sugar. The safety of metoprolol during pregnancy is not fully established. Metoprolol reduces long-term mortality and hospitalisation due to worsening heart failure. This medicine may cause changes in blood sugar levels or cover up signs of low blood sugar, such as a rapid pulse rate.

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.

Morphology of the intrinsic cardiac nervous system in the dog: a whole-mount study employing histochemical staining with acetylcholinesterase. Circ Res 91 , — PMC Copyright notice. Heart Vessels 18 , 32— Produces vasodilation and anti-inflammatory effects may help treatment of HF. J Card Fail 23 , — Results The patient characteristics are given in Table 1. 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, and facilitate identification and specific targeting of arrhythmia provoking conditions by autonomic drugs. Lancet 2 , 57— J Neurosci Methods , 48— 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. Comparative quantitative study of the intrinsic cardiac ganglia and neurons in the rat, guinea pig, dog and human as revealed by histochemical staining for acetylcholinesterase. This may contribute to the sympathetically-mediated increase in conduction velocity and formation of reentrant arrhythmias after MI, which is often characterized by myocardial depolarization Nattel et al. 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.

Effects on mortality and morbidity in acute myocardial infarction. Heart Rhythm 6 , — Ser of connexin43 and the upregulation of gap junction assembly by cAMP. Nat Med 11 , — Has membrane-stabilizing action, but no sympathomimetic activity. Acebutolol Some sympathomimetic and membrane stabilizing activity. Altered cardiac myocyte Ca regulation in heart failure. Science , — The relative amount of connexin in each sample was investigated by comparison of gray scale value of target proteins with the gray scale signal of GAPDH. 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. A study in awake chronically instrumented goats. Functionally, in AF patients, transverse conduction velocity in atrial samples was significantly enhanced and this change was also significantly antagonized by metoprolol. Sympathetic activation leads to increased heart rate chronotropy , force of contraction inotropy , speed of relaxation lusitropy , and conduction dromotropy. Eur J Pharmacol , —
