Dilated cardiomyopathy in the cat

The aetiology of primary dilated cardiomyopathy in the cat is unknown. Recent work has indicated a close association between dietary taurine deficiency and dilated cardiomyopathy. In the cat, taurine is an essential amino acid which is required for the conjugation of bile acids. The premise that taurine deficiency is one of the causative factors in… Read More »

Bradycardia

Symptomatic bradycardia results from problems of impulse generation in the sinus node and / or its conduction from the atria to the ventricles. Both of these processes are influenced by the autonomic nervous system with the parasympathetic system slowing and the sympathetic system accelerating impulse generation and conduction. Non-cardiac causes of bradycardia Sinus bradycardia is… Read More »

Dilated Cardiomyopathy: Acute Therapy

Treatment Goals The treatment goals depend on the type and severity of the clinical signs. If severely dyspneic the initial goal is to make it easier for the cat to breathe by removing pleural effusion, by reducing pulmonary edema pharmacologically, or by administering oxygen. If the primary problem is a marked reduction in perfusion leading… Read More »

Hemolytic Anemia

Hemolytic anemia is a pathologic condition that results from accelerated erythrocyte removal and can be intravascular and extravascular. Intravascular hemolysis occurs when erythrocytes are destroyed within the vascular space. Clinical signs associated with intravascular hemolysis are typically acute in onset and classically include icterus and red- to port-wine-colored urine. Extravascular hemolysis results from accelerated erythrocyte… Read More »

Heart Failure: Treatment Strategies

Management of Acute Decompensated Congestive Heart Failure Dogs with dilated cardiomyopathy or mitral regurgitation often present with acute onset of coughing, dyspnea, restlessness, orthopnea, and weakness subsequent to the development of severe pulmonary edema and/or low cardiac output. The immediate priorities in these patients are resolution of the pulmonary edema, maintenance of adequate tissue perfusion… Read More »
