Cardiac Arrest in Cats
Cardiac Arrest in Cats - Symptoms, Causes, Diagnosis, Treatment, Recovery, Management, Cost
What is Cardiac Arrest?
This condition can be reversed, but it requires immediate veterinary care to lower the risk of serious complications. Cardiac arrest can become fatal without prompt treatment from a veterinary professional.
Cardiac arrest in cats occurs when regular blood circulation stops, which causes the heart to stop beating. This can happen when cats are unable to breathe normally for several minutes. The respiratory system and cardiovascular system in cats normally work together to ensure regular blood circulation, a normal heart rate, normal breathing and healthy blood pressure levels. When the respiratory system is affected by illness or trauma, oxygen levels in the blood can drop low enough to lead to cardiac arrest.

Symptoms of Cardiac Arrest in Cats
Cardiac arrest is considered a life-threatening emergency for cats, so it is important for owners to know the symptoms of it. Signs of this condition include:
  • Breathing heavily
  • Showing no response to stimulation
  • Losing consciousness
  • Having pupil dilation
  • Having bluish gums, skin and mucous membranes, which indicates dangerously low levels of oxygen in the bloodstream
  • Having a low body temperature, also known as hypothermia
Causes of Cardiac Arrest in Cats
Cardiac arrest in cats can occur for a number of reasons. Possible causes of this condition include the following:
  • Oxygen levels in the blood that are too low
  • A low supply of oxygen
  • Heart disease
  • A metabolic disease
  • An electrolyte imbalance
  • Brain injuries
  • Low levels of bodily fluids
  • Blood poisoning from toxic bacteria in the bloodstream
  • Shock from trauma
  • Anesthesia for medical procedures
Diagnosis of Cardiac Arrest in Cats
A prompt and accurate diagnosis of cardiac arrest in cats is important in order for veterinarians to treat it properly. A diagnosis includes providing a veterinarian with information on the cat’s medical history and details on when symptoms began to appear and what types of symptoms occurred. Owners should also tell a veterinarian any relevant details that might help explain why their cat went into cardiac arrest, such as an injury or possible exposure to toxic substances. This can help veterinarians treat or manage underlying conditions after they have restored cardiac function. Doing so can help stabilize cats and lower the risk of complications. 
Veterinarians typically do a physical exam that includes checking circulation and respiration for any abnormalities. This exam also involves regularly monitoring blood pressure and checking pulse rates. Veterinarians also perform tests to determine what is causing cardiac arrest. Common tests that are used include X-rays of the chest, blood samples to check the levels of oxygen and other gases, echocardiography to check for evidence of heart disease and a complete blood count. Other tests that are often done include a biochemistry profile and urine tests, which help veterinarians find out what might have led to cardiac arrest.
Treatment of Cardiac Arrest in Cats
Since cardiac arrest in cats is an emergency, prompt veterinary care is required. Owners should bring cats to the nearest veterinary hospital or emergency clinic for treatment. 
Cardiopulmonary Resuscitation
Immediate medical care by veterinary professionals involves getting the heart to begin beating again and restoring its natural rhythm, as well as returning the cat’s respiration rate to normal. Veterinarians do this by clearing the airways and performing cardiopulmonary resuscitation. In some cases, veterinarians place a tube down the airways to help keep breathing regular. They might also administer oxygen to restore normal levels of this gas in the bloodstream. Medications that help support regular cardiac function are usually given to cats that are under cardiac arrest. 
Cardiac Massage and Compressions
Another method of restarting the heart involves performing cardiac massage on the chest, which is sometimes required in cats that have heart failure. When this is ineffective, veterinarians might perform chest compressions. These compressions involve pushing down on the chest rapidly to get the heart beating again. 
Open Chest Resuscitation
If cardiac massage and chest compressions are unsuccessful, veterinarians might make incisions in the chest in order to restart the heart. They might also inject medications into the heart to try to restore a heartbeat.

Recovery of Cardiac Arrest in Cats
Cardiac arrest in cats has a low recovery rate, although this depends in part on what caused this condition to occur and how soon treatment began. The type of treatment that was used can also have an impact on recovery. For example, cats typically require a longer time to recover after having open chest resuscitation. 
Cats usually have to stay in a veterinary hospital for the first few days after treatment to ensure that their condition stabilizes. During this time, veterinarians frequently check blood pressure, cardiac function and respiratory function. If any complications occur, these are treated promptly to help increase the chance of a successful recovery. Owners should bring their cats in for follow-up visits as often as needed.

It is never easy having an unexpected loss of a loved one like this and it is normal to be looking for answers; one of his eyes being a little open and the other one closed is not diagnostically relevant and may have been moved during handling. Unfortunately I cannot shed any light on Copper’s death and would advise you request a necropsy to be done at a Pathology Laboratory or another Practice to try to uncover the cause of Copper’s passing.

My pet has the following symptoms:
Lethargy
Loss Of Appetite
Labored Breathing
No Appetite
My cat's problem started with vomiting, loss of appetite , and lethargy. After couple days she had labored breathing. We took her to her vet who said the cat seems fine to him and gave her 4 shots. Vit B injection, cerenia for nausea, an antibiotic and steroid shot. That evening her breathing became very labored so i took her to an emergency vet care. Chest x-rays showed fluid in her chest and an enlarged liver. Vet's treatment plan included oxygen therapy and lasix. 6 hours later she went into cardiac arrest and 2 minutes later she died. She had no known medical problems at all so her death is a shock. I'm looking for answers as to why this happened so fast? Please give some info. Thanks.

Sorry to read about your loss. It is normal to look for answers after loosing a loved one, especially when it is unexpected and quick; but I can only give some possibilities and no definitive answers. Lethargy and loss of appetite are vague signs which may apply to numerous conditions, the laboured breathing may have been caused by infection, heart failure, fluid in the lungs, pain response, tumours, anaemia (not enough red blood cells to carry oxygen), fever or trauma; the increase in liver size may have been caused by tumours, systemic disease, blood vessel abnormalities or poisoning. Liver disease is a probable cause; however, without carrying out a necropsy, we cannot know for 100% what caused Princesses death. Regards Dr Callum Turner DVM

My pet has the following symptoms:
None
I came back from short vacation. While I was away, friend was looking after my 2 cats. My Mim was as always happy to see us, we cuddly a little, then when I was checking apartment she was with me, then I gave my cats some snacks and I went to sit on a couch. After 2 minutes cats came to me, we again cuddle a little. Then Mimi was sitting 20cm away from me, she was cleaning herself. Everything was perfectly normal. Then I saw her paw in a strange movement, then still up in the air, I heard strange noise from her and after a second she was lying on her belly, front paws stretched in front of her. I was with her in a second, I pick her up but she was so flabby. No response. I didn’t know what to do. I scream her name and I cuddle her, we went to vet clinic, while in a car her body fluids (I think it was urine) came down on me a bit. When we got to the clinic and I lay her on the table all the urine came down, vet saw her tongue, check her heart with stethoscope and said that she is gone. I have no idea what happened. In the end of July we did check up at vet, blood work. Everything was fine. I can’t forgive myself that I didn’t do CPR immediately. I was in such a shock. Maybe it would help. It’s been 5 days and I can’t cope with her sudden death :(

My pet has the following symptoms:
None
I took my perfectly healthy cat to the groomers to get his “lion cut” as I had been doing for three years. The groomer texted me in 25 minutes that SeaRay would be done in 5 minutes. I arrived 10 minutes later to pick her up. The groomer told me my SeaRay was fine during the grooming she put her back in her cat cArrier and then noticed that she wasn’t breathing. I arrived right then. The groomer took her out of the carrier and said she wasn’t breathing and she couldn’t feel a heart beat—she started mouth to mouth on her tried to compress her chest but SeaRay slumped over—I rushed her out to the car to take her to vet but she died in my arms. She was only 6 years old—her last check up my excellent vet said she was hearing a little heart murmur but she didn’t seemed concerned about it. What on earth happened to my cat? This groomer loved my SeaRay— it was loud at her house with the dog barking. Did my SeaRay get stressed and die from cArdiac arrest?

My pet has the following symptoms:
Subdued, Hiding, Reduced Appetite
I had my 7 month old male kitten neutered almost 4 weeks ago. Over the past three to four days, he became a little quiet, more than usual, and not as big of an appetite. Went to feed him this morning and found him lying on the floor dead. It appeared as if he was sleeping. He did not have any obvious signs and symptoms of illness other than what I expressed. When I moved him I noticed about 15 cc's of saliva dripped from his mouth. I was assuming that this was just part of the purging although there was no urine or feces present. I am perplexed as to what had happened to him so I Googled and found that a percentage of cats can die from 12 hours to six weeks after having anesthetics from surgery. It can cause myocardial problems. I am heartbroken and don't know what else to think. Has anyone experienced anything like this?
