Myocardial infarction complicating management of congestive heart failure in a dog

Journal of the American Animal Hospital Association

Abstract

A 7.5-kg, 10-year-old, spayed female, mixed-breed dog was evaluated for sudden onset of weakness, tachypnea, and an irregular cardiac rhythm. Congestive heart failure secondary to mitral valve regurgitation had been diagnosed six weeks earlier. The dog was stable on furosemide, enalapril, and hydralazine. Complex ventricular tachycardia, altered QRS conformation of sinus complexes, echocardiographic evidence of a hypokinetic left-ventricular free wall, and elevated creatine kinase suggested a diagnosis of myocardial infarction. Despite antiarrhythmic therapy, the dog developed ventricular fibrillation and died 36 hours after admission. Postmortem examination confirmed the myocardial infarction. Although a rare diagnosis in the veterinary patient, myocardial infarction must be considered in the differential diagnosis for sudden onset of weakness, tachypnea, and ventricular tachycardia.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.
