Heart disease and heart failure are different
Heart disease means there is a problem with the heart’s structure or function. Heart failure is a possible consequence: the heart cannot meet the body’s needs adequately, and fluid may collect in the lungs or elsewhere. A pet can have heart disease without being in heart failure. Looking well does not rule out a problem, but a diagnosis does not automatically mean a crisis or an immediate need for every heart medicine.
Which heart conditions might my vet discuss?
- Degenerative mitral valve disease: a valve becomes leaky, allowing some blood to flow backwards. It is particularly associated with older, smaller dogs, although other dogs can be affected.
- Dilated cardiomyopathy (DCM): the heart muscle pumps less effectively and chambers may enlarge. Some larger dog breeds have increased risk; breed alone cannot confirm a diagnosis.
- Hypertrophic cardiomyopathy (HCM): thickening of the heart muscle is an important condition in cats. Some affected cats have no obvious symptoms.
- Congenital defects: some animals are born with abnormal connections or narrowed pathways in the heart. Young pets may also need investigation. These are internationally recognised conditions, not a ranking of disease frequency in Sri Lanka.
Changes to mention at your appointment
Tell your vet about reduced stamina, unusual tiredness, changes in breathing at rest, weakness or fainting. Coughing can have airway and lung causes as well as heart-related causes, so a cough alone cannot diagnose heart failure. Write down when changes began and bring a short video if you can record one without delaying care. Describe the activity before an episode and how your pet recovered.
Does a murmur mean serious heart disease?
A murmur is an extra sound produced by disturbed blood flow. It is a finding, not a complete diagnosis, and its loudness alone does not establish the severity of disease. Some pets with heart disease have no audible murmur. Ask what the vet heard, whether it is new, and how soon further assessment is recommended. Do not wait for symptoms if a follow-up has been advised.
Why might more than one test be needed?
- Echocardiography uses ultrasound to assess heart structures, valves and pumping. It helps explain the cause of some abnormal sounds.
- Chest X-rays assess the chest and lungs; an ECG records electrical rhythm. These answer different questions from a heart scan.
- Blood pressure and selected blood tests help assess other illnesses and treatment safety. Your vet chooses a combination based on the examination and history.
Treatment and monitoring depend on the findings
Some pets need monitoring before medication is appropriate; others benefit from treatment earlier in their disease. Never share another pet’s tablets or change prescribed doses yourself. Ask for a written plan covering medicines, exercise, follow-up and signs that should prompt a call. If home breathing monitoring is advised, ask for a demonstration and an individual action threshold. Take previous reports and medicine packets when attending another clinic in Sri Lanka.
When should I seek emergency help?
Difficulty breathing, collapse, or sudden painful weakness or paralysis of a cat’s back legs needs urgent veterinary assessment. Contact an available emergency veterinary service and arrange prompt transport. Keep handling and exertion low. Do not wait for an online appointment reply or a scheduled scan. An unstable pet may need immediate support before a detailed diagnostic examination.
Questions owners often ask
- Can a normal-looking pet still need a scan? Yes. Tests can investigate findings before obvious symptoms develop.
- Will treatment cure the condition? That depends on the diagnosis. Many conditions require continuing management and reassessment.
- What should I ask before leaving? Confirm the suspected diagnosis, the reason for each test, the estimated cost and the next review date.
