pyrimidinones and Syndrome

Acute coronary syndrome causes several types of arrhythmia because of its electrical instability and ischemia. The most important arrhythmia is ventricular tachycardia which degenerates to ventricular fibrillation. Prompt direct current cardioversion will be needed and prevention of ventricular tachyarrhythmia by potassium channel blocker became more popular in Japan. Nifekalant or amiodarone should be selected. Atrial fibrillation also occurred in the patients with acute coronary syndrome, and it may deteriorate hemodynamics condition. Therefore, termination and prevention of atrial fibrillation is another important issue in acute coronary syndrome. Aprindine, amiodarone, or bepridil will be the choice to prevent recurrent atrial fibrillation after direct current cardioversion.

Arteriovenous malformations (AVMs) have recently been reported to have a high incidence of somatic KRAS mutations suggesting potential for treatment with mitogen-activated protein kinase inhibitors. In this case report, we describe genotype-targeted treatment of a KRAS mutant metameric AVM in a patient with Cobb syndrome using the mitogen-activated protein kinase inhibitor trametinib. Therapeutic response was monitored with phase-contrast magnetic resonance angiography to quantify AVM arterial inflow as an imaging biomarker. Treatment with trametinib resulted in a substantial decrease in blood flow to the AVM, with a >75% reduction in arterial inflow after 6 months of trametinib therapy.

We assessed several pharmacological effects on electrocardiogram parameters and effective refractory period (ERP) in a patient with a short QT syndrome (SQTS). Pharmacological challenge tests revealed that disopyramide and selective I(kr) blocker, nifekalant normalized QT interval, and ERP of the atrial and ventricular myocardium. This study suggested that disopyramide and nifekalant should be feasible for the drug treatment of the SQTS. Moreover, QT interval was paradoxically prolonged at higher heart rates induced with isoproterenol infusion or an exercise test, although the mechanism of this QT prolongation remains to be investigated.
