What is cardiomegaly and how does it affect dogs?

Cardiomegaly is a term that refers to the enlargement of the heart. It is not a disease by itself, but a consequence of other underlying conditions that affect the heart function. The heart is a muscular organ that pumps blood throughout the body, delivering oxygen and nutrients to the tissues and organs. The heart has four chambers: two auricles (or atria) and two ventricles. The auricles receive blood from the veins and send it to the ventricles, which then pump it to the arteries. The right ventricle sends blood to the lungs, where it gets oxygenated, and the left ventricle sends blood to the rest of the body.

When the heart is affected by some disease or disorder, it may have difficulty pumping blood efficiently. This can cause a buildup of blood and pressure in the heart chambers, which leads to their dilation and enlargement. This can also affect the valves that regulate the blood flow between the chambers, causing them to leak or narrow. As a result, the heart becomes weaker and less able to meet the body’s demands for oxygen and nutrients. This can cause symptoms such as fatigue, coughing, breathing difficulties, fainting, swelling and fluid accumulation in the abdomen or lungs.

Cardiomegaly can affect dogs of any age, breed or gender, but some factors can increase the risk of developing this condition. These include genetic predisposition, age (older dogs are more prone), obesity, infections, parasites, toxins, trauma and other diseases (such as diabetes, thyroid problems or kidney failure). Cardiomegaly can be classified into two types: dilated cardiomyopathy and hypertrophic cardiomyopathy. Dilated cardiomyopathy is when the heart chambers become enlarged and thin-walled, and hypertrophic cardiomyopathy is when the heart walls become thickened and stiff. Both types can impair the heart function and cause heart failure.

What are the main causes of cardiomegaly in dogs?

The exact cause of cardiomegaly in dogs is unknown, but there are some factors that can contribute to the development of this condition. Some of these factors are:

Nutritional deficiencies: Some breeds, such as Boxers and Cocker Spaniels, are prone to develop cardiomegaly due to a lack of taurine or carnitine, which are amino acids that are essential for the heart function. A balanced diet that provides enough protein and vitamins can help prevent this problem.
Infectious diseases: Some infections, such as parvovirus, distemper, Lyme disease or heartworms, can damage the heart muscle and cause inflammation and enlargement. A regular vaccination and deworming schedule can help protect your dog from these diseases.
Genetic predisposition: Some breeds have a higher risk of developing cardiomegaly due to a genetic mutation that affects the heart structure or function. Some of these breeds are Doberman Pinschers, Boxers, Newfoundlands, Scottish Deerhounds, Irish Wolfhounds, Great Danes and Cocker Spaniels. In some breeds, such as Great Danes, males are more affected than females. If your dog belongs to one of these breeds, you should consult your veterinarian about the best screening and prevention methods.
Other diseases: Some conditions that affect other organs or systems can also affect the heart and cause cardiomegaly. For example, diabetes, thyroid problems, kidney failure or obesity can increase the workload of the heart and cause it to enlarge. A regular check-up and blood tests can help detect and treat these diseases before they affect the heart.

Cardiomegaly can be classified into two types: dilated cardiomyopathy and hypertrophic cardiomyopathy. Dilated cardiomyopathy is when the heart chambers become enlarged and thin-walled, and hypertrophic cardiomyopathy is when the heart walls become thickened and stiff. Both types can impair the heart function and cause heart failure.

What are the signs and symptoms of cardiomegaly in dogs?

Cardiomegaly in dogs can cause various signs and symptoms that depend on the severity and type of the condition. Some of the signs and symptoms are:

Exercise intolerance and a general slowing down: This is one of the common signs of cardiomegaly in dogs, especially in the early stages of the disease. Dogs with cardiomegaly may tire easily, show less interest in playing or walking, and prefer to rest more often.
Lethargy and weakness: Dogs with cardiomegaly may also show signs of lethargy and weakness, due to the reduced blood flow and oxygen delivery to the tissues and organs. They may have difficulty getting up, standing or walking, and may collapse or faint in some cases .
Loss of appetite: Dogs with cardiomegaly may lose their appetite and weight, due to the reduced blood flow to the digestive system, nausea, abdominal discomfort or pain .
Coughing and panting: Dogs with cardiomegaly may cough and pant more than usual, especially with activity or excitement. This is due to the fluid accumulation in or around the lungs, which causes breathing difficulties and reduces oxygen exchange . The cough may be soft or dry, or may produce frothy or bloody sputum in some cases.
Abdominal distension: Dogs with cardiomegaly may develop a pot-bellied appearance, due to the fluid accumulation in the abdomen. This can cause abdominal pressure, pain, bloating and reduced appetite .
Labored breathing: Dogs with cardiomegaly may show signs of labored breathing, such as increased respiratory rate or effort, flared nostrils, open mouth breathing or cyanosis (bluish coloration of the gums or tongue). This is due to the reduced oxygen delivery to the body and the increased work of breathing .
Muffled breathing or crackling sound while breathing: Dogs with cardiomegaly may have muffled breathing or a crackling sound while breathing, due to the presence of fluid in the lungs. This can also cause coughing and panting.
Irregular or weak pulse: Dogs with cardiomegaly may have an irregular or weak pulse, due to the abnormal heart rhythm or reduced heart function. This can be detected by feeling the pulse on the inside of the hind leg or by using a stethoscope.
Slow capillary refill time: Dogs with cardiomegaly may have a slow capillary refill time, which indicates poor circulation. This can be tested by pressing on the gums gently and observing how long it takes for them to turn pink again. A normal capillary refill time is less than two seconds.

Some of these signs and symptoms may not be specific for cardiomegaly, and may be caused by other conditions. Therefore, it is important to consult a veterinarian if you notice any changes in your dog’s health or behavior.

How is cardiomegaly diagnosed in dogs?

Cardiomegaly in dogs can be diagnosed by a veterinarian using various methods and tests. Some of these are:

Physical examination: A veterinarian can examine your dog’s heart using a stethoscope to detect any abnormal sounds, such as murmurs or irregular rhythms. However, these signs may not be always detectable, especially in the early stages of the disease. A veterinarian can also check your dog’s pulse, blood pressure, capillary refill time, temperature and breathing rate to assess their general health and circulation.
Chest radiographs: A veterinarian can take X-rays of your dog’s chest to measure the size and shape of their heart and to look for any fluid accumulation in or around the lungs. This can help determine the type and severity of cardiomegaly .
Blood and urine tests: A veterinarian can take blood and urine samples from your dog to evaluate the function of other organs that may be affected by heart disease, such as the kidneys, liver and thyroid. These tests can also help rule out other causes of cardiomegaly, such as infections or toxins.
Electrocardiogram (EKG): A veterinarian can attach electrodes to your dog’s chest to record the electrical activity of their heart. This can help detect any arrhythmias or ventricular tachycardia that may be associated with cardiomegaly.
Echocardiogram: A veterinarian can use an ultrasound device to create an image of your dog’s heart and its chambers, valves and blood flow. This is considered the gold standard for diagnosing cardiomegaly in dogs, as it can provide detailed information about the structure and function of the heart .
Holter monitor: A veterinarian can attach a device to your dog’s chest that records their heart activity for 24 hours. This can help monitor any changes or abnormalities in their heart rhythm that may not be detected by a single EKG.

These tests can help confirm a diagnosis of cardiomegaly in dogs and determine its cause, type and severity. They can also help plan the best treatment and management options for your dog.
