Lysophosphatidylcholine (LPC), which accumulates in the ischemic myocardium, is responsible for mechanical and metabolic derangements of hearts, and also contributes to the development of ventricular arrhythmias. We examined the effects of pravastatin on the LPC-induced cardiac dysfunction in isolated rat hearts. Rat hearts were randomly divided into four groups. The groups comprised a control group (n=10), a group treated with LPC (5 microM) (n=20), a group treated with pravastatin (400 ng/ml) (n=10) and a group treated with both LPC and pravastatin (n=20). Our data suggest that, pravastatin possesses some protective profiles against LPC, as manifested by better recovery of cardiac function (improvement in heart rate, left ventricular developed pressure, maximal and minimal first derivatives of left ventricular developed pressure, coronary flow and coronary resistance, less release of biomarkers of cardiac injury (lactate dehydrogenase, creatine kinase-MB and endothelin-1), and attenuation of ventricular arrhythmias (ventricular tachyarrhythmia and ventricular fibrillation).

UI MeSH Term Description Entries
D007770 L-Lactate Dehydrogenase A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist. Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase
D008244 Lysophosphatidylcholines Derivatives of PHOSPHATIDYLCHOLINES obtained by their partial hydrolysis which removes one of the fatty acid moieties. Lysolecithin,Lysolecithins,Lysophosphatidylcholine
D008297 Male Males
D006321 Heart The hollow, muscular organ that maintains the circulation of the blood. Hearts
D006352 Heart Ventricles The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.

D006439 Hemodynamics The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM. Hemodynamic
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D013610 Tachycardia Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia. Tachyarrhythmia,Tachyarrhythmias,Tachycardias
D014693 Ventricular Fibrillation A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST. Fibrillation, Ventricular,Fibrillations, Ventricular,Ventricular Fibrillations
D017035 Pravastatin An antilipemic fungal metabolite isolated from cultures of Nocardia autotrophica. It acts as a competitive inhibitor of HMG CoA reductase (HYDROXYMETHYLGLUTARYL COA REDUCTASES).
