A first cardiac workup for a cat costs 700 to 1,400 dollars in the US, 500 to 1,050 pounds in the UK, and 950 to 2,750 yuan in China. The echocardiogram is 55 to 65 percent of that total at 400 to 800 dollars, and once a cat is diagnosed the bill does not stop: rechecks every 3 to 6 months run 200 to 450 dollars each, so the first 12 months usually land between 1,100 and 2,300 dollars.
The four pieces of a cardiac workup
A workup is not one test. Auscultation and a blood pressure reading come first at 60 to 120 dollars, and a murmur graded 3 out of 6 or louder is what triggers the rest. Two-view chest radiographs at 150 to 300 dollars show heart silhouette and whether there is pulmonary edema. An ECG at 100 to 200 dollars catches arrhythmia that a 30-second listen misses. The echocardiogram at 400 to 800 dollars measures wall thickness, left atrial size and the LA/Ao ratio, and it is the only test that separates hypertrophic cardiomyopathy from hyperthyroid heart disease or from a normal heart with a loud murmur.
Why the echo dominates the bill
An echo takes 30 to 45 minutes of a trained operator plus a machine that costs more than a car. A general practitioner with a cardiac ultrasound course charges 250 to 450 dollars; a board-certified cardiologist charges 450 to 800 dollars for the same study plus a written report. That 200 to 350 dollar gap buys interpretation, not images: the difference between a left atrial measurement reported to 0.1 cm and a paragraph saying the heart looks enlarged. NT-proBNP, a blood test used when echo is not available, adds 60 to 120 dollars and returns a number rather than a diagnosis.

Prices assume a mid-size city in 2026 and swing 1.5 to 3 times by city and hospital tier. A university cardiology service sits at the top of every row; a municipal clinic with a visiting sonographer at the bottom. The echo row moves least within a country, because the equipment and the operator are the cost, and most by country, which is why the China total runs at roughly a quarter of the UK total at 2026 exchange rates.
The 3 to 6 month recheck, and what changes it
Asymptomatic cats with moderate disease are usually rechecked every 6 months; cats on medication, or with a left atrium above 1.8 cm, every 3 months. Each recheck repeats the echo at 200 to 450 dollars, plus bloodwork every 6 months at 80 to 180 dollars to watch renal values on diuretics. Three rechecks a year at the 3-month interval is 600 to 1,350 dollars, which is more than the original workup, and it is the number most owners do not see coming.
Monthly drug costs once treatment starts
Prices only, because doses are set by the cardiologist and by weight. Furosemide runs 10 to 30 dollars a month, pimobendan 60 to 150 dollars, benazepril 15 to 40 dollars, clopidogrel 10 to 30 dollars, and a potassium supplement 10 to 25 dollars where diuretics deplete it. A cat on 3 drugs is 100 to 220 dollars a month, or 1,200 to 2,600 dollars a year, in the US; UK prices are 60 to 70 percent of that, China 40 to 60 percent. Compounded liquids cost 20 to 40 percent more than tablets but are the only option for a cat that will not take a pill.
A CHF crisis costs 3 to 5 times a recheck
Congestive heart failure is an emergency bill, not a clinic bill. A cat arriving with open-mouth breathing needs oxygen, furosemide and often 24 to 48 hours in an oxygen cage: 600 to 1,500 dollars in the US, 400 to 900 pounds in the UK, 2,000 to 6,000 yuan in China, before any diagnostic test. Most cats survive the first crisis, and the 3 months that follow are the most expensive quarter of the disease, typically 1,500 to 3,500 dollars.
What a 150-dollar screening buys
A murmur picked up at a routine visit starts a decision, not a diagnosis. A listen plus a blood pressure reading at 60 to 120 dollars tells you whether the murmur is grade 1 to 2 or grade 4 to 6, and whether systolic pressure is above 160 mmHg and needs its own treatment. When a murmur turns up in a cat that came in for itching, the cardiac bill stacks on top of the skin workup priced in cat allergy workup cost, and both sets of tests usually land in the same week. Skipping the echo and rechecking in 12 months is a defensible choice in a 3-year-old with a grade 1 murmur and no clinical signs; in a 9-year-old with a gallop sound it usually costs more later, since a first crisis at 600 to 1,500 dollars exceeds the 400 to 800 dollar echo it would have replaced. The frequency side of the math is laid out in vet visit frequency and cost.
When to go now, not at the recheck
Four signs override any appointment schedule: breathing more than 40 times a minute at rest, open-mouth breathing, blue or grey gums, and sudden paralysis of the hind limbs with cold pads, which points to an aortic thromboembolism. A cat with any of these needs an emergency hospital within the hour; survival in thromboembolism is poor even with treatment, and the cost of attempting it runs from 1,000 to 3,000 dollars for the first 48 hours alone. Sleeping respiratory rate is the at-home number that matters: count breaths for 30 seconds while the cat sleeps, multiply by 2, and record it 3 times a week.
Five steps before the first echo
- Ask whether the sonographer is a cardiologist; the fee difference is 200 to 350 dollars and the report differs.
- Request the measurement table, not just a conclusion, so future rechecks compare like with like.
- Do baseline bloodwork on the same day, since diuretics change renal values within 2 to 4 weeks.
- Book the 6-month recheck before leaving; cardiology slots run 3 to 6 weeks out.
- Track sleeping respiratory rate at home and bring 4 weeks of numbers to each visit, using the cost calculator to log what each visit included.
Frequently asked
Can a regular vet do the echo instead of a cardiologist?
Yes, if the practice has a cardiac ultrasound course and a machine with Doppler. The price difference is 200 to 350 dollars, and the practical difference is the report: a cardiologist gives chamber measurements, LA/Ao ratio and a staging recommendation, while a general scan may give only a visual impression. For a first diagnosis, the measurement table is what future rechecks are compared against.
How often does a cat with HCM need an echo?
Every 6 months for asymptomatic cats with moderate disease, every 3 months once medication starts or the left atrium exceeds 1.8 cm. Each study is 200 to 450 dollars, and bloodwork every 6 months adds 80 to 180 dollars, so a cat on the 3-month schedule costs 600 to 1,350 dollars a year in monitoring alone.
If the first echo is normal, when is the next one due?
Twelve months for a 3-year-old cat with a grade 1 murmur and no clinical signs, at 200 to 450 dollars. Six months for a cat with a gallop sound, an arrhythmia, or an enlarged heart silhouette on X-ray, even if the first study looked close to normal. Wall thickness is measured in fractions of a millimeter, so one normal reading does not exclude early disease.
