aconitine and Coronary-Artery-Disease

Tachyarrhythmias (TA) - dangerous postoperative complications of coronary artery bypass grafting, threatening the lives of patients and found, according to different authors, in 13-40% of cases. VFS - an antiarrhythmic drug that belongs to a class 1C, is effective in the treatment and prevention of a variety of cardiac arrhythmias. The aim of the work was to study the clinical efficacy of VFS CHD patients with a history of tachyarrhythmias during the perioperative period of coronary bypass surgery, as well as its comparison with other antiarrhythmic drug (amiodarone). Clinical efficacy was evaluated in 218 patients with coronary heart disease at baseline with a history of tachyarrhythmia (paroxysmal atrial fibrillation or premature ventricular high grade (IV and V class on classification of Lown B. and Wolf M. in the modification of Ryan M.). Shown that the VFS is more effective than amiodarone, both in paroxysmal atrial fibrillation and ventricular arrhythmias when high gradation.

We have found that intravenous administration of cannabinoid receptor (CB) agonist HU-210 (0.05 mg/kg), increases cardiac resistance against arrhythmogenic effect of epinephrine, aconitine, coronary artery occlusion and reperfusion in rats. Pretreatment with CB2-receptor antagonist, SR144528 (1 mg/kg), completely abolished the antiarrhythmic effect of HU-210. However this effect of HU-210 was not attenuated by pretreatment with CB1-receptor antagonist, SR141716A (3 mg/kg). We also found that HU-210 (0.05 mg/kg) decreased the relationship between infarction size and area of ischemia. It is concluded that CB2 receptor stimulation promotes an increase in the cardiac resistance against arrhythmogenic influences and probably increases myocardial tolerance of both ischemic and reperfusion damages in rats.
