Heart Disease: The Silent Pet Killer That You Can Now Avoid

In this informative video, Dr. Karen Becker discusses a wonderful new tool for early detection of heart disease in dogs and cats.

Dr. Becker's Comments:

Heart disease in companion animals is too often a silent killer.

By the time your dog or cat shows the classic signs of heart disease like lethargy, wheezing, croupy coughing (a liquid-sounding cough, as though there’s fluid in the lungs) or exercise intolerance, it’s very often too late to save your beloved pet.

To make matters worse, an enlarged heart can’t be detected with a stethoscope. Significant heart disease can be present and undiagnosed by your veterinarian long before your pet shows clinical symptoms of illness.

Too many pet owners too often find themselves in this heartbreaking situation.

Two Types of Heart Disease

Both dogs and cats are at risk for heart disease, and both can develop either type:

  1. Heart muscle disease
  2. Valvular disease

Cardiomyopathy is the scientific term for an enlarged heart muscle.

Some breeds of dogs are predisposed to the condition, including New Foundlands, Great Danes and Dobermans.

Cardiomyopathy can also be caused by a dietary deficiency. The amino acids taurine and carnitine are critical for normal heart development and performance. If your dog’s or cat’s diet is lacking in these amino acids, heart muscle damage can result.

Poor valve health can also lead to heart disease. A leaky valve makes your pet’s heart work harder, and the harder it works, the bigger it gets. Valve disease leads to congestive heart failure in both dogs and cats.

Heart murmurs (which are usually present when there are valve problems) are ranked on a scale from 1 to 6, where 1 is considered mild and 6 is the worst case.

Leaky valves or heart murmurs are frequently seen in predisposed breeds like the Cavalier King Charles Spaniel.

Leaky valves are also found in aging pets and animals with some metabolic conditions like feline hyperthyroidism.

Diagnosing Heart Disease in Your Pet

If your veterinarian suspects a heart problem -- usually by hearing a murmur through a stethoscope, by doing a physical examination, and/or by considering symptoms your dog or cat is experiencing -- diagnostic tests will be required to confirm presence of disease.

These tests, usually x-rays, EKG or cardiac ultrasound, can cost several hundred dollars.

For many pet owners who want to be proactive in detecting heart disease in a dog or cat, the expense of these tests is prohibitive.

It’s a terrible situation to be in. If you’ve lost a dog or cat to heart disease, you’re bound to be fearful it could happen again to another pet. You want to take proactive steps to help your current dearly loved dog or cat avoid the problem, but you can’t afford the tests that will tell you whether or not you need to do more to insure the health of your companion animal.

It feels as if you have no choice but to wait to see if heart disease sneaks up silently to claim another four-legged member of your family.

That is, until now.

A Blood Test for Early Detection of Heart Disease in Pets

This is wonderful news!

At long last, veterinary medicine has developed a blood test that can identify which dogs and cats are at greatest risk for heart disease and heart failure.

The test is called a proBNP test. BNP = B-type Natriuretic Peptide.

The proBNP is a blood test that measures how much peptide hormone, released by the heart, is in circulation in your pet’s body. This hormone is only released when the heart is pushed beyond its capacity.

Very early in the disease process, small amounts of the hormone will be released into your dog’s or cat’s bloodstream, and it’s presence is a signal that steps must be taken in order to preserve your pet’s heart health.

If heart pathology continues to progress, the blood value of the peptide hormone will continue to rise.

How to Proactively Protect Your Pet’s Heart Health

  1. Ask your veterinarian for the proBNP blood test if you’re concerned about your pet’s heart for any reason.

    The proBNP blood test can give you peace of mind that your pet has no early signs of heart disease.

    It can also help you and your veterinarian differentiate between, for example, a respiratory condition like feline asthma and an underlying heart condition.

    The proBNP is a simple blood test with a fast turn-around time that can provide the information you need to proactively manage your dog’s or cat’s heart health. You can have the test repeated as often as necessary to chart your progress in meeting your pet’s cardiovascular health needs throughout his life.

  2. Make sure you’re meeting your pet’s CoQ10 requirement . CoQ10 is a naturally occurring coenzyme that young dogs and cats have in plentiful supply. But as she ages, your pet’s ability to produce CoQ10 decreases.

    I recommend you supplement your pet’s amino-acid-rich diet with Coenzyme Q10, especially if you have an animal that is predisposed to cardiovascular disease. Supplying your pet with extra CoQ10 can insure she has the quantity her body needs to maintain a healthy heart muscle.

    CoQ10 supplements come in two forms: Ubiquinone and Ubiqunol. Ubiquinol is a reduced form of CoQ10 and is the supplement I recommend for my dog and cat patients. A good heart-healthy maintenance dose is:

    • 50 mg per day for cats and small dogs
    • 100 mg per day for medium sized dogs
    • 100 mg twice per day for large dogs
