Heart disease in cats can be difficult to spot, especially in the early stages when symptoms are subtle or absent.
Certain cat breeds are more frequently associated with inherited or breed-linked heart conditions, which is why veterinarians often monitor them more closely.
This does not mean every cat of these breeds will develop heart problems, but awareness can help owners recognise risk factors sooner.
Genetics, overall health, and regular veterinary care all play an important role in outcomes.
Understanding which breeds are more commonly linked to heart conditions can support earlier check-ups and better long-term care.
This article is for general knowledge only and is based on information from online sources.
Health risks vary between individual cats regardless of breed.
Always consult a qualified veterinarian for diagnosis, screening, and treatment advice.
1. Maine Coon

With a heart as grand as its size, the Maine Coon unfortunately carries a heavy genetic burden when it comes to cardiac health.
Studies show that up to one-third of these majestic felines may carry a mutation linked to hypertrophic cardiomyopathy.
This condition causes the heart muscle to thicken abnormally, making it harder for the organ to pump blood effectively.
Owners of Maine Coons should schedule regular echocardiograms, especially as their cats reach middle age.
Early detection can help manage symptoms and improve quality of life.
Despite this risk, many Maine Coons live long, happy lives with proper veterinary care and monitoring.
2. Ragdoll

Known for going limp when picked up, Ragdolls have an easygoing personality that endears them to families everywhere.
However, beneath that docile exterior lies a genetic vulnerability to heart disease.
A specific mutation puts Ragdolls at increased risk for hypertrophic cardiomyopathy.
Breeders now test for this mutation to reduce its prevalence, but existing cats still need vigilant monitoring.
Veterinarians recommend baseline heart screenings for Ragdolls around one year of age. Symptoms like laboured breathing or lethargy should never be ignored.
With early intervention and medication, many Ragdolls manage their heart condition successfully throughout their lives.
3. British Shorthair

That round, teddy bear face hides a serious health concern for British Shorthairs.
Research indicates these cats develop hypertrophic cardiomyopathy at rates higher than mixed-breed populations.
Their stocky build and calm demeanour make it easy to miss early warning signs.
Weight management becomes especially important since obesity can compound cardiac stress.
Regular check-ups should include listening to the heart for murmurs or irregular rhythms.
Some British Shorthairs show no symptoms until the disease progresses significantly.
Responsible breeders now screen their breeding cats, but adopters should still request cardiac evaluations for peace of mind and proactive health management.
4. Sphynx

Their hairless bodies and wrinkled skin make Sphynx cats instantly recognizable, but their hearts carry hereditary risks that require attention.
Veterinarians link this breed to higher incidences of hypertrophic cardiomyopathy.
The lack of fur means owners can sometimes feel their cat’s heartbeat more easily, which might help notice irregularities.
Early and routine echocardiographic screening offers the best chance for catching problems before symptoms appear.
Sphynx cats benefit from environments that keep them warm, as temperature regulation already taxes their systems.
Adding heart disease to the mix requires extra vigilance. Fortunately, many veterinary cardiologists specialize in feline heart conditions.
5. Persian

Those luxurious coats and flat faces come with more than grooming challenges.
Persians face a notably higher incidence of hypertrophic cardiomyopathy compared to many other breeds.
Their brachycephalic features already make breathing less efficient, so cardiac issues can compound respiratory difficulties.
Owners should watch for increased breathing effort, reduced activity, or coughing.
Annual heart screenings become particularly important after age five.
Some Persians carry the condition without showing obvious symptoms for years.
Genetic testing helps breeders make informed decisions, but all Persians deserve cardiovascular monitoring.
With medication and lifestyle adjustments, affected cats can still enjoy comfortable, fulfilling lives surrounded by their favourite people.
6. Bengal

Wild looks and energetic personalities make Bengals fascinating companions, but their hearts may not match their athletic appearance.
This breed shows susceptibility to hereditary hypertrophic cardiomyopathy.
The heart muscle gradually thickens, reducing the chamber space available for blood.
Active Bengals might mask early symptoms through sheer energy and enthusiasm.
Sudden collapse during play or exercise can be a red flag requiring immediate veterinary attention.
Responsible Bengal breeders conduct cardiac screenings on their breeding stock.
If you have a Bengal, ask your vet about baseline echocardiograms.
Early detection allows for treatment plans that can extend and improve your cat’s active lifestyle considerably.
7. Norwegian Forest Cat

Built for Scandinavian winters, Norwegian Forest Cats possess impressive coats and sturdy frames.
Unfortunately, their genetic heritage also includes predisposition to cardiac problems.
Hypertrophic cardiomyopathy affects this breed at concerning rates.
Their large size means their hearts already work hard to pump blood throughout their bodies.
Adding muscle thickening to the equation creates additional strain.
Owners should schedule regular veterinary exams that include cardiac auscultation.
Some Norwegian Forest Cats develop symptoms in middle age, while others remain asymptomatic for longer.
Maintaining a healthy weight helps reduce cardiovascular stress.
These magnificent cats deserve the best preventive care available to protect their noble hearts.
8. Birman

Legend says Birmans gained their white paws from a temple goddess, but no myth protects them from heart disease.
These gentle cats rank among breeds predisposed to hypertrophic cardiomyopathy.
Their serene temperament sometimes masks symptoms that more active breeds might display more obviously.
Lethargy in an already calm cat can be easy to overlook.
Veterinary cardiologists recommend echocardiograms for Birmans, particularly those from lines with known cardiac issues.
Some cats show heart murmurs during routine exams, prompting further investigation.
Treatment options include medications that help the heart function more efficiently.
Many Birmans respond well to management strategies, continuing to grace their homes with beauty and companionship.
9. Chartreux

France’s national cat treasure carries a smile-like expression and a dense blue coat.
Sadly, Chartreux cats also carry elevated risks for developing hypertrophic cardiomyopathy compared to mixed-breed cats.
Their muscular build and quiet nature make them wonderful companions, but their hearts need regular monitoring.
Reports show this breed develops cardiac issues at higher rates than average.
Veterinarians can detect heart murmurs or gallop rhythms during physical exams.
Echocardiograms provide detailed images of heart structure and function.
Chartreux owners should establish relationships with vets experienced in feline cardiology.
Medication can help manage symptoms and slow disease progression in many cases.
10. Siberian

Russia’s forest cat boasts a triple coat and remarkable agility.
Despite their robust appearance, Siberians face genetic predisposition to heart disease, particularly hypertrophic cardiomyopathy.
Their playful, dog-like personalities make them family favourites.
However, owners need to stay alert for signs of cardiac trouble.
Decreased playfulness or reluctance to jump could indicate developing problems.
Regular veterinary visits should include thorough cardiac examinations.
Some Siberians benefit from genetic testing to identify mutations associated with heart disease.
Breeders who test their cats help reduce the prevalence in future generations.
Meanwhile, existing Siberians deserve careful monitoring and prompt intervention if symptoms appear, ensuring they enjoy their naturally long lifespans.
11. Oriental Breeds

Siamese, Burmese, and Balinese cats share more than striking looks and vocal personalities.
These Oriental breeds face heightened risks for various health conditions, including cardiac concerns.
Their slender builds and active natures sometimes disguise developing heart problems.
Changes in behaviour or breathing patterns warrant immediate veterinary attention.
While these breeds face multiple genetic health challenges, heart disease remains a significant concern.
Regular screenings help catch issues before they become critical.
Oriental breeds benefit from relationships with veterinarians familiar with their specific health profiles.
Many of these cats live long lives with proper care, filling their homes with conversation and affection despite their genetic vulnerabilities.
12. Devon Rex

Pixie faces and wavy coats give Devon Rex cats an otherworldly appearance.
Their playful antics and affectionate nature make them beloved companions, but their hearts carry genetic vulnerabilities.
Devon Rex cats rank among breeds predisposed to hypertrophic cardiomyopathy.
Their small size means even minor cardiac changes can have significant impacts.
Veterinarians recommend baseline heart evaluations for Devon Rex cats.
Owners should monitor for symptoms like rapid breathing, weakness, or fainting.
These social cats often follow their people everywhere, making behaviour changes easier to notice.
With proper screening and intervention, many Devon Rex cats manage heart conditions successfully while maintaining their signature playful, loving personalities throughout their lives.
