Hematologic markers better predict left ventricular assist device thrombosis than echocardiographic or pump parameters.

Background: Left ventricular assist device (LVAD) thrombosis is a life-threatening complication that remains a major clinical problem. Consensus diagnostic criteria do not exist. We investigated whether hematologic, echocardiographic, or pump parameters reliably change during LVAD thrombosis.

Amiodarone - a 'broad spectrum' antiarrhythmic drug.

Amiodarone, an iodinated benzofuran derivative, introduced in 1960's as an anti-anginal agent, emerged as a potent anti-arrhythmic agent by 1970's and is currently one of the most commonly prescribed drugs in US for ventricular and atrial arrhythmias. Although amiodarone is considered a class III anti-arrhythmic agent, it also has class I, II, IV actions, making it a unique and effective anti-arrhythmic agent. Because of its minimal negative inotropic activity and very low rate of pro-arrhythmia, it is considered safe in treating arrhythmias in patients with Coronary Artery Disease and Left ventricular systolic dysfunction.
