Treatment of cardiovascular disease should be specific for the type of disease. Some defects can be repaired or corrected with surgery, while other conditions can be managed with medical therapy using one or a combination of drugs. In dogs with congestive heart failure, a low-sodium diet may be recommended to help eliminate excess fluid in the body.
In general, the goals of treatment are to minimize damage to the heart muscle, control the accumulation of fluids in the lungs, improve circulation, regulate the heart rate and rhythm, ensure that there is enough oxygen in the blood, and minimize the risk of blood clot formation. In heartworm disease, the mature heartworms and larvae should be killed. Ultimately, the goals are achieved when treatment resolves the signs, the breathing and heart rates are normal at rest, and the dog has a good quality of life.
Common Types of Drugs for Cardiovascular Disease
There are many medications that a veterinarian can prescribe for dogs with cardiovascular disease. The type of disease will determine the type of medication prescribed. Medications must be given exactly as prescribed; otherwise, they may not be effective and may even cause serious complications and harm.
One common type of medication used for heart problems is a diuretic. Diuretics are medicines that increase urine output. These medicines are important and effective means for removing fluids that accumulate in dogs with heart problems. The use of a diuretic can be life saving when a dog is in a crisis caused by heart failure.
Some drugs, such as the digitalis glycoside called digoxin, increase the force of heart muscle contraction, slow the heart rate, and allow blood pressure receptors to work better. They are used to treat heart failure. Drugs called ACE inhibitors Drugs Heart failure is not a specific disease or diagnosis. It is a syndrome in which severe dysfunction results in failure of the cardiovascular system to maintain adequate blood circulation. There... read more are also used in heart failure in dogs. They can reduce blood pressure, improve heart output, and reduce the backward flow of blood caused by a leaky heart valve. Pimobendan, another drug often used for congestive heart failure, has been shown to improve the quality of life and survival times in dogs with the disease. Sildenafil dilates arteries leading to the lungs and is used to treat high blood pressure in the lungs.
Other types of drugs can strengthen respiratory muscles and improve breathing. Some medications are prescribed to control arrhythmias, slow or speed heart rate, and prevent blood clots. In other cases, medications are provided to kill heartworms or other parasites in the cardiovascular system.
As with any disorder, your veterinarian will evaluate your pet and provide medication appropriate for its condition. It is your responsibility to follow through and provide your pet with the correct dose of medicine on the schedule prescribed by your veterinarian.
