Cardiology

This online on-demand archived Webinar will introduce you to a classification scheme for heart disease and heart failure and will discuss the clinical significance of signalment, history and common cardiac diagnostic tests to appropriately stage dogs and cats with heart disease. (1 CE credit)

What is the aim of this heart disease treatment?

One of the biggest risk factors for this condition in cats.

Technicians aren't all destined to be cardiologists. But all technicians should understand what a normal cardiac rhythm looks like and how it's generated.

New guidelines give veterinarians a tool for managing these cases in dogs.

Does the obesity paradox in people occur in cats as well?

Blood pressure measurement is often not a routine part of small animal practice. This partially has to do with the equipment available to measure blood pressure as well as our patients (they tend not to hold still like we have to).

Cardiovascular (CV) diseases in cats include congenital malformations, acquired heart, and vascular disorders. Myocardial disorders or cardiomyopathies, the major cause of heart failure, thromboembolism, and persistent arrhythmias in cats, constitute the focus of this presentation.

Arrhythmias can be classified based on ECG analysis based on the heart rate (normal, bradyarrhythmias, tachyarrhythmias); anatomic origin of the rhythm disturbance (SA, atrial, atrioventricular, or ventricular); or electrophysiologic mechanism when evident.

Acquired heart diseases of dogs include chronic degenerative valvular diseases (endocardiosis), pericardial diseases, cardiac neoplasia, dilated cardiomyopathy (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), pulmonary hypertension (PH), infective endocarditis, and heart rhythm disturbances, some of which represent primary electrical disorders and others that develop secondary to cardiac remodeling.

The technician should appreciate the definition and causes of CHF, as well as methods of evaluation. The drugs used to treat CHF should be understood, as well as related side-effects. This awareness improves both patient care and client communications.

The signs of pulmonary parenchymal vascular disease are not always obvious.

February is National Heart Month and a good time to save cats from cardiac disease.

What is the most common cause of pericardial effusion in dogs?

Is there an indicator for severity of cardiac disease in dogs?

Orlando -- Pioneering veterinary cardiologist Stephen Ettinger, DVM, Dipl. ACVIM received the 2011 Mark L. Morris Sr., Lifetime Achievement Award yesterday.

How can hydration status influence echocardiographic measurements?

An important aspect of diagnosis of this disorder in American cocker spaniels.

Anesthetizing a patient with cardiac disease requires a plan for the use of supportive measures to maintain adequate tissue perfusion. As in the case of left sided cardiac dysfunction patients, volume administration frequently is not an option to support blood pressure. In these cases, should a positive inotropic or pressor agent be indicated, the volume of the adjunctive agent required should be deducted from the volume of crystalloid administered to maintain a balanced hourly rate.

Thromboembolism is a fairly common and potentially devastating complication of heart disease in cats.

The patient suspected of having a cardiac problem needs to have a complete history taken and physical examination performed; these procedures will establish the correct diagnosis and permit appropriate therapy. The cardiac examination is an extension of the complete physical examination.

Determine age, breed, and sex of the patient to help formulate a rule-out list and help to determine prognosis. Note current pre-existing diseases. Record current drugs and clinical response. Record presenting clinical signs and duration and progression of the illness.

Electrocardiography is an integral part of the cardiological exam. It is the only way to determine heart rhythm accurately and to determine if there are any conduction abnormalities. This is also the most useful part of an ECG. ECGs can do other things however, these are not nearly as important.

I'll review the pathophysiological changes associated with the common congenital and acquired cardiac defects in small animal medicine and discuss the characteristics of anesthetic drugs that may make them desirable of undesirable for each problem.

Chronic heart failure (CHF) traditional therapy (for CHF secondary to chronic degenerative valvular disease etc.) still provides only an average a 4-6 months survival time in dogs. Though current standard treatment regimens provide a good quality of life for many canine patients, complications can lead to early patient loss.

The essentials of electrocardiography include the assessment of heart rate, heart rhythm, and the P-QRS-T waveforms. The ECG is needed to accurately diagnose cardiac arrhythmias, and this test is extremely sensitive for this purpose.

Advancing technology has provided clinicians with ever more powerful and effective drugs for treating diseases. As more drugs become available, it becomes progressively more difficult to be aware of the numerous side effects, contraindications, and drug interactions of the many cardiopulmonary drugs available.

ECG case studies.

The clinical signs of canine and feline heart failure are limited, but they must be distinguished from pulmonary dysfunction and also systemic problems. Heart disease often results in secondary respiratory signs (e.g., coughing or dyspnea); conversely, disease of the lung or its vasculature can result in secondary right heart disease (e.g., cor pulmonale).
