If your four-legged best friend has heart disease, here are some key questions to ask your veterinarian.
- What type of heart disease does my pet have?
- How is it best treated?
- How will I know if treatment is working?
- What symptoms should I be watching for?
- When should my pet be rechecked?
- Can you refer me to a specialist?
Diagnosis of heart disease
Tests used to confirm the diagnosis of heart disease commonly include:
- A thorough physical examination that includes auscultation (listening to the heart and lungs with a stethoscope.)
- Blood tests including screening for heartworm disease.
- An electrocardiogram (ECG) to evaluate the rhythm of the heartbeats.
- Chest X-rays to evaluate the size of the heart and identify abnormal fluid in or around the lungs.
- An echocardiogram (an ultrasound evaluation that provides a look inside the heart) to evaluate valve function, chamber size, and the strength of heart contractions.
What to look for
Early and advanced warning signs of heart disease can include:
- Increased respiratory rate
- Restlessness during sleep
- Decreased stamina
- Vomiting (occurs in cats)
- Loss of appetite
- Labored breathing
- Distention of the abdomen with fluid
- Blue/purple tinged tongue and gums
- Sudden death
- Sudden paralysis of the hind legs caused by a blood clot within the aorta (occurs in cats)
