Dilated cardiomyopathy – Heart Failure in Dogs

Author: Wishbone

Cardiomyopathy refers to diseases of the heart muscle (myocardium) without malformation of the heart or its valves. The mean cardiomyopathy literally "heart disease." It is a breed predisposition to dilated cardiomyopathy in giant breeds, and doberman pinschers and boxers. Dilated cardiomyopathy is the most common cause of heart failure in dogs in general. However, this is the most common heart failure in dogs of large breeds. Small breeds are rarely affected. The breeds most often affected are the boxers, doberman pinschers and Great Danes. Sometimes, half breeds, including Cocker Spaniels and English Springer Spaniels are also affected. Cardiomyopathy can also develop in response to certain toxins or infections. Heart failure occurs when the return of blood to the heart of the rest of the body can not pump fast enough to meet the application of body tissues. Disease of the heart muscle is one possible cause of heart failure. Dilated cardiomyopathy is a disease characterized by a variety of changes in heart muscle pump. As its name suggests, the heart chambers are enlarged or dilated and the heart muscle in it is usually thin and weak, contracting with much less force than normal. The heart works harder to compensate for the loss of contractility, with eventually leads to congestive heart failure. Abnormalities in heart muscle cells give rise to irregularities in heart rate, causing sudden death Petsafe in May is good if needed.

Dilated cardiomyopathy is most common in dogs. There is room for expansion of the heart ventricles with a increase (hypertrophy) in the heart of muscle mass and loss of normal ventricles contract. Dilated cardiomyopathy or DCM, occurs when the heart muscle is weak, weak, and not function properly. DCM most effect on dogs or giant purebred, but can also be seen in more races Small dogs like cocker spaniels and mixed race. The condition can lead to congestive heart failure, in which fluid accumulates in the lungs, thoracic cavity or abdominal, or under the skin. Due to reduced blood flow to the rest of the body, DCM also can result in weakness, fainting, and exercise intolerance. Rhythms abnormal heart rhythm, which often accompany DCM, and can complicate the treatment of dogs suffering from this disease. It is also common for dogs with DCM to show signs of right heart failure and two left. These signs can include weakness and exercise intolerance, and greater difficulty in breathing for the activity. Weight loss is common in dogs with DCM that do not retain fluid. Some animals exhibit signs due to reduced blood flow to tissues, including the membranes pale mucous membranes, bluish color of mucous membranes, and cold feet and legs. Fainting can occur abnormal heart rhythm, if present, or if the heart of production is very low. Hypertrophic cardiomyopathy is a form of cardiomyopathy, a large increase in the mass of the heart muscle in the ventricles, with the consequent reduction in the size of the camera. Relatively few cases of hypertrophic cardiomyopathy was reported in dogs breed predisposition and was not identified. Most of the affected dogs were male.

Blood and urine tests do not provide direct information on cardiac function, but can include other disorders of the body, in May of that impact on cardiac function and treatment of heart disease. Chest x-rays (rays X) to provide the best image in the lungs and a view of the size and shape heart. In most cases, dilated cardiomyopathy cause enormous enlargement of the heart. These changes are very evident on x-rays.lectrocardiogram (ECG or EKG) is an assessment of the heart's electrical activity. Accurately determining the heart rate and to better identify arrhythmias that may be present. Ultrasound (sonogram, echocardiogram) uses sound waves that bounce off the structures of the heart and are read on a TV instructor. It is the most accurate determination of the dimensions of each chamber of the heart, and enables measurement of wall thickness of the heart. We see on the screen in real time so that the contraction of the heart can be assessed. Some measures can be taken to allow the contraction of the heart to be measured in numbers and compared with normal animals. Ultrasound may not be available in all private veterinary practices because of the training needed to learn how to conduct the review and because the cost of equipment.

If the dog has a sudden onset of heart failure, rapid for the proper administration of drugs is essential for survival. Medicines can be used at various stages after treatment. Diuretics stimulate the kidneys to remove excess fluid from the body. Furosemide is the most commonly used, but others will be chosen in certain circumstances. Nitroglycerin venodilator is a medication that dilates the veins in the body, especially those who go to the heart muscle. Decreasing the amount of blood returning to the heart by allowing some of them to save in the veins. It takes the workload on the heart. It can be very useful for the treatment of pulmonary edema, but is only effective for about days. Digitalis medicines improve heart function in several ways. Regulates excess hormones that have been released, slowing the heart rate and strengthens each contraction of the heart. Blockers of the enzyme is a relatively new class of drugs that can directly block the compensation system that has lost control. Vasodilating drugs dilate the arteries and / or the veins of the body, so the heart does not generate as much pressure to eject blood. Can be used long term, as they remain effective, as opposed to short-term effects of nitroglycerin. Dogs treated with these drugs should be carefully monitored toxity and enough for the needs of pet beds. Loss of appetite, vomiting, diarrhea, lethargy and should be reported immediately to a veterinarian.
