The hemodynamic and antiadrenergic effects of dronedarone, a noniodinated compound structurally related to amiodarone, were compared with those of amiodarone after prolonged oral administration, both at rest and during sympathetic stimulation in conscious dogs with a healed myocardial infarction.
OBJECTIVE IKr blockade is ineffective in preventing ventricular fibrillation elicited by the interaction between acute myocardial ischemia and elevated sympathetic activity. This depends in part on the fact that adrenergic activation offsets more than 50% of the action potential prolonging effect of
Delta-opioid receptors are known to participate in the protection found following ischemic preconditioning (IPC), but the role of kappa-receptors in IPC is currently controversial. Langendorff-perfused rat hearts received 35 min regional ischemia and 2 h reperfusion. PC (2 cycles 5 min global
OBJECTIVE Cardioprotective adaptation to brief periods of ischemia and reperfusion is termed ischemic preconditioning (PC). Limitation of infarct size by preconditioning is associated with marked slowing of ischemic metabolism. The cause of metabolic slowing has not been determined but may involve

Carvedilol versus metoprolol in the acute phase of myocardial infarction:.

Beta-adrenergic blockers provide significant cardioprotection during acute ischemia and reperfusion. To further explore the effects of additional alpha-1-adrenoceptor blockade on autonomic modulation in acute myocardial infarction (AMI), carvedilol was compared with metoprolol in the setting of
In animal studies, amiodarone has substantial and immediate antiarrhythmic/antifibrillatory action during acute myocardial ischemia. The magnitude of this effect is discordant with the minor degree of prolongation of ventricular action potential duration (APD) and refractoriness which occurs
OBJECTIVE Acute myocardial infarction (AMI) is associated with increased coagulation which in the presence of unstable atheroma or endothelial damage leads to occlusive coronary vessel thrombosis. AMI is usually characterized by increased levels of catecholamines. It is possible there may be a link
Melatonin has potent cardioprotective properties. These actions have been attributed to its free radical scavenging and anti-oxidant actions, but may also be receptor mediated. Melatonin also exerts powerful anti-adrenergic actions based on its effects on contractility of isolated papillary muscles.
Over the last 3 decades, there have been numerous experimental and clinical studies that utilized beta blockers for acute as well as chronic myocardial syndromes, especially in the setting of myocardial infarction in which the focus has been on mortality reduction. The results of these studies

[Antianginal and antiadrenergic therapy in acute coronary syndrome].

In recent years cardiology has opened new chapters in the treatment of acute coronary syndrome (ACS). The acute therapeutic procedures include antianginal, anticoagulant and revascularization therapy. Optimal therapeutic procedure in ACS has two objectives: 1) quick removal of the factors causing
Acute myocardial infarction (AMI) is a common cause of hospitalisation and high mortality due to lethal arrhythmias. Sarcoplasmic reticulum Ca2+ ATPase (SERCA2) and ryanodine receptor (RyR2) regulate the cytosolic Ca2+ ion concentration. Rosmarinic acid (RA) is one of the most common caffeic esters
BACKGROUND Phosphodiesterase 2 is a dual substrate esterase, which has the unique property to be stimulated by cGMP, but primarily hydrolyzes cAMP. Myocardial phosphodiesterase 2 is upregulated in human heart failure, but its role in the heart is unknown. OBJECTIVE To explore the role of

Carvedilol protects against lethal reperfusion injury through antiadrenergic mechanisms.

We examined the effect of carvedilol as compared with that of a combination of propranolol and doxazosin on lethal reperfusion injury in 21 feline hearts subjected to 40-min regional ischemia and 180-min reperfusion. A control group (n = 7) was compared with one group given carvedilol, a

A 55-year-old patient with inferior wall infarction was treated effectively for ventricular tachycardia with high-dose oral amiodarone loading regimen (5 g within 16 hours). Serial pharmacokinetic studies demonstrated a rapid temporary increase in amiodarone plasma concentration to a maximum of 3.40

Ventricular arrhythmias: antiadrenergic therapy for the patient with coronary artery disease.

Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Patients who have had a recent myocardial infarction (MI) are at high risk of ventricular arrhythmias that often cause sudden cardiac death. It is believed that sympathetic overactivity in the peri-infarction period may alter the electrophysiology and structure of the myocardium, thus placing these
