The cause of DCM is unclear in most cases, but certain breeds appear to have an inherited predisposition. Medications for treatment for DCM are relatively inexpensive, but given that it is a chronic, progressive condition, costs can add up.

The cause of canine DCM is subject to debate. © 2020 Great Pet Media. Two main classes are beta-blockers (such as atenolol, sotalol, carvedilol) and calcium channel blockers (such as diltiazem). All Rights Reserved 2020. Furthermore, the biomarker N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) appears very promising in correctly identifying dogs with preclinical DCM. If arrhythmias are not controlled with the above medications, antiarrhythmic drugs may be added in cautiously. Updated June 27, 2019. Dogs with DCM should not be bred in order to prevent hereditary DCM. Furosemide dosing may require adjustments, because treatment requires carefully balancing the need to remove excess fluid with the need to prevent dehydration. There are very few studies addressing the potential benefit of treating preclinical DCM. This cause-specific mortality can only be matched by myxomatous mitral valve disease in cavalier King Charles spaniels (2.5% per year at risk). Diuretics such as lasix are used to help control and prevent accumulation of fluid disease within 6 months. She lives with her husband, daughter, three cats, one dog, and a pet dove. Pimobendan and/or and ACE-inhibitor are often added to the diuretic therapy once the diagnosis of DCM has been established. A procedure to physically remove the buildup of fluid in the dog’s abdomen or chest cavity may be used for DCM cases that are more severe. In order to diagnose DCM, your veterinarian will first perform a thorough physical exam. A variety of drugs may be used to control arrhythmias, including diltiazem, digoxin, mexiletine, procainamide, lidocaine, amiodarone, and others.

Therefore, taurine supplements for dogs may not prevent this condition and should not be used unless there is confirmed laboratory evidence of taurine deficiency. Initial stabilization usually depends on the first two. Histopathological characterization of dogs with DCM has shown that there are two histopathological phenotypes that presumably precipitates different clinical presentations. or develop an arrhythmia (irregular heartbeat) that disrupts circulation. 5. In the 1980s, a similar rise in DCM developed in cats. In dogs that are already showing signs of heart failure, enalapril is given to dilate blood vessels.

Guidelines for the Diagnosis of Canine Idiopathic Dilated Cardiomyopathy; The ESVC Taskforce for Canine Dilated Cardiomyopathy. Neutraceuticals such as taurine/L-carnitine and omega-3 fatty acid supplementation may be considered. Enalapril: In dogs that are already showing signs of heart failure, enalapril is given to dilate blood vessels. For the asymptomatic patient, the challenge lies in differentiating normal variation and cardiac or non-cardiac pathologies from DCM. Ideally, clients should choose a diet that is manufactured by a well-established company following the World Small Animal Veterinary Association (WSAVA) Global Nutrition Committee Guidelines. Evaluation of diastolic function may be valuable for determining prognosis as it has been shown in dogs that a restrictive pattern on mitral inflow and a short E wave deceleration time (<80 milliseconds) were significantly associated with a poor prognosis. Many dogs with DCM are tachycardic and may potentially benefit from heart rate control by adding digoxin or a beta-receptor blocker. The Dobermans and boxers presenting with ventricular tachyarrhythmias have myocardial lesions that include myocytolysis, myofibre degeneration, vacuolization and myocyte atrophy with extensive fibrosis and fatty infiltration. Further research revealed that many of these reported cases occurred in dogs fed grain-free or boutique diets. Jens Haggstrom, DVM, PhD, DECVIM-CA (Cardiology) These changes interfere with the heart’s ability to pump normally, limiting efficient blood flow throughout the body. Veterinary cardiologists began observing an increase in cases of dilated cardiomyopathy in dogs, often occurring in breeds that are not typically predisposed to the disease.

In most dogs with DCM, blood tests such as complete blood cell count and serum biochemistry are common. Treatment: There are no proven strategies for preventing the development of DCM, although many medical protocols and nutritional supplements have been proposed. In the case of atrial fibrillation, therapy is usually aimed at reducing ventricular rate by introducing digoxin (0.22mg/m2 q12h or lower), or a beta-blocker (carvedilol (maximum dose 0.5 mg/kg q12h), metoprolol (maximum dose 1 mg/kg q8h), atenolol (maximum dose 1 mg/kg q12h), or propranolol (maximum dose 1 mg/kg q8h)).

DCM Reversal Possible with Early Intervention. Taurine deficiency may contribute to the development of DCM in some dogs, particularly Golden Retrievers who may have a genetic predisposition to deficiency. Cardiac dilatation may also present with an arrhythmia, most commonly atrial fibrillation, but the histopathological findings include myocytes that are thinner than normal with a wavy appearance that are separated by a clear space, indicating edematous fluid that is generally free from cellular infiltrates; there may also be diffuse infiltration of subendocardial fibrosis. In dogs with cardiac dilatation, ACE-inhibitors (0.5 mg/kg q12-24h is the usual dose for most of the ACE-inhibitors) and/or the inodilator pimobendan (0.25 mg/kg q12h) are often introduced. The nutrient scientists are looking into now is taurine. It’s no mystery that what we eat plays an important role in a wide variety of diseases, including cancer and heart disease. Dietary changes or medications can help manage the condition. Chest radiographs are primarily used to look for evidence of congestive heart failure, although they can also suggest the presence of DCM if significant heart enlargement is seen.

Leave a comment on Canine DCM Symptoms: What Would Dilated Cardiomyopathy (DCM) Look Like in Your Dog? Treatment: Cardiac medications are delivered by injection in emergency situations and orally in stable patients. Pimobendan helps the heart beat more strongly and dilates blood vessels (allowing blood to flow through the body more easily). Dilated cardiomyopathy (DCM) is a disease of the heart muscle that is characterized by an enlarged heart that does not function properly. That problem was eventually linked to commercial pet foods being deficient in taurine, an amino acid found in animal protein. As the disease progresses the heart chambers become enlarged, one or more valves may leak, and signs of congestive heart failure develop. The echocardiographic diagnosis of DCM is based on the identification of myocardial (predominantly but not solely systolic) dysfunction with the active exclusion of other acquired or congenital cardiac disease. These techniques allow characterization of global and regional myocardial function, which not only gives insight to the pathophysiology and characterization of myocardial disease in dogs, but appears to allow identification of diseased individuals before conventional echocardiography.
