Canine Heart Disease. In dogs like man, heart function is vital to life! Today over 3 million dogs already suffer from heart disease; many of whom are already in heart failure. When the heart is unable to pump blood at the rate necessary to meet the needs of your dog’s body, heart failure is the result.
Canine Heart Failure
Two forms of heart disease occur in dogs: Dilated Cardiomyopathy (DCM) and Mitral Valve Insufficiency (MVI). In Dilated Cardiomyopathy the muscle of the heart’s wall becomes thin and weak. The result is that the heart muscle cannot contract properly and circulation is impaired. In Mitral Valve Insufficiency the fibers of the heart valve degenerate. The valve can no longer close correctly which impairs blood flow and circulation. Cardiomyopathy is common in large breeds, like Great Danes, whereas Mitral Valve Disease usually occurs in older small breeds, notably miniature poodles and dachshunds. Signs of heart failure include getting tired easily; coughing, especially when waking up in the morning; difficulty breathing; fainting; weakness; and lack of energy.
FACT: Chest x-rays illustrate the size and shape of the heart and lungs, either of which may be abnormal with heart disease.
WHAT YOUR VET CAN DO
Routine diagnostics for heart disease include blood and urine tests, chest x-rays, and an electrocardiograph, which detects electrical disturbances in the heart. An echocardiography may be recommended which helps pinpoint the specific problem within the heart. An echocardiogram works similarly to an ultrasound machine and allows more in-depth visualization of the heart.
Treatment will vary depending on the specific type of heart disease. Options generally include one or all of the “four Ds” of heart failure therapy: low sodium diet; diuretic medication which reduces fluid buildup in the lungs by stimulating the kidneys to eliminate the excess, vasodilators or medication geared to help dilate or enlarge veins which promotes proper blood flow; and Digitalis, another cardiac medication that encourages the heart to beat stronger and more slowly. This helps the heart pump blood more efficiently and more effectively.
Pacemaker surgery is an effective treatment for electrical disturbances in the heart that are unresponsive to medical management. These dogs generally faint, have a slow heart rate and get tired easily with exercise. The pacemaker is inserted surgically through the jugular vein and placed down into the heart. The wires are attached to a pulse generator which is placed under the skin of the neck. The pacemaker is effective for the lifetime of the dog. Postoperative care is minimal. Because of the location of the pacemaker’s generator in the dog’s neck, a harness as opposed to, a collar is necessary for all cases.
COMPLEMENTARY TREATMENTS – HOMEOPATHIC REMEDIES
Crataegus oxycantha 3x (Hawthorne berry) is helpful for heart weakness and heart murmurs: one pellet on the tongue once daily for 30 days. Withhold food 10 minutes before and after treatment. (Use with caution in certain Hypertrophic forms of Cardiomyopathy.)
Digitalis purpurea 6x (foxglove) may be helpful when the heartbeat is irregular. One tablet for fainting or episodes of distressed breathing that occurs after exercise. Cactus Grandi floras 6c is recommended when there is poor circulation because of heart valve problems. As opposed to humans who need treatment for Arteriosclerosis and Hypertension, medications geared to support heart muscle function are most helpful in dogs and cats with heart failure.
