Can Birds Have Heart Attacks? [Explained]

It’s unsettling to see a bird perish unexpectedly. You may ask whether the cardiovascular crises that affect humans also affect birds. Can our feathery companions get heart attacks similarly to how we do?

Here’s a fast response if you’re pressed for time: Although they are not medically comparable to heart attacks in people, birds may have abrupt, deadly cardiac episodes that are somewhat similar.

This three thousand word essay will compare the cardiovascular biology of humans and birds, examine heart disorders that may afflict birds, and investigate the reasons of unexpected heart-related fatalities in our feathered friends.

The Hearts of Birds and Humans

Birds and humans have some amazing distinctions in terms of the cardiovascular systems. The way their hearts are built is one of the most obvious differences. Birds’ hearts are two chambered, but human hearts are four chambered.

Because of this difference in cardiac structure, birds are able to fly and manoeuvre through the air with ease.

Two-Stomach Avian Hearts

The right ventricle and right atrium make up the two chambers of a bird’s heart. The blood can flow through their bodies more effectively because to its sleek design. In contrast to humans, birds lack a distinct left atrium and left ventricle.

Rather, blood that is low in oxygen and blood that is high in oxygen combine in the right atrium before being circulated throughout the body.

For birds to engage in high-energy activities like flight and long-distance migration, their hearts have developed a special adaption. Birds’ two chambered hearts allow them to sustain the flow of oxygen they need and their high energy levels during demanding activity.

Disparities between Blood Pressure and Heart Rate

The fascinating variations in heart rate and blood pressure between the hearts of birds and humans. Compared to humans, birds often have faster heart rates. Humans, for instance, typically have resting heart rates between 60 and 100 beats per minute, whereas tiny birds may have resting heart rates as high as 400 to 500 beats per minute.

Birds are able to sustain their high metabolic needs and busy lives due to their higher heart rate.

In addition, the heart rates of birds may fluctuate faster than those of humans. During flying, birds find this versatility very helpful. In order to meet the demands of various flying speeds and manoeuvres, they may instantly alter their heart rate, providing a steady flow of oxygen to their muscles.

Differentiations in Electrophysiology

Bird hearts are not only structurally and functionally different from human hearts, but they also show differences in their electrophysiological. Action potentials, which are electrical impulses that control the heart’s contractions, are unique in birds.

These variations enable avian hearts to withstand oxygen deprivation better, which is advantageous for long-distance flight or other situations in which the birds must hold their breath.

Heart Problems in Birds

Similar to us, birds may have different cardiac problems. Although humans are often linked to heart attacks, are heart attacks also possible in birds? Let’s look at a few cardiac ailments that may impact our feathery companions.

The atherosclerosis

Birds may also get atherosclerosis, sometimes referred to as artery stiffening. This disorder is brought on by the accumulation of fatty deposits on the artery walls, which narrows the blood vessels and lowers blood flow.

Heart attacks are among the cardiovascular issues caused by atherosclerosis in birds.

Some bird species, such ducks and penguins, may have a higher prevalence of atherosclerosis, according to studies. These birds may acquire fatty deposits in their arteries as a result of eating high-fat diets.

Furthermore, the development of atherosclerosis in birds may also be influenced by environmental factors like pollutants.


Birds are not exempt from arrhythmias, or abnormal cardiac beats. Similar to us, birds’ regular heartbeats are sustained by a coordinated electrical system in their hearts. Abnormal cardiac rhythms may result from disruptions to this electrical system, however, which can be caused by underlying heart disease, stress, or genetic susceptibility.

Bird arrhythmias may manifest as weakness, lethargic behaviour, and dyspnea. It may potentially cause abrupt death in extreme circumstances. Owners of birds should be aware of the warning indications of arrhythmias and should seek medical attention if they think their bird may be impacted.

Heart Attack vs Anaphylaxis

Birds may have cardiac problems, but it’s important to realise that the terms and processes may not be the same as in human medicine. Veterinarians more typically refer to myocardial infarction—the destruction of heart muscle as a result of inadequate blood supply—instead of “heart attack.”

Atherosclerosis, blood clots, and other underlying cardiac diseases are among the many causes of myocardial infarction in birds. Furthermore, damage to the heart muscle may result from anoxia, or the absence of oxygen reaching the heart muscle.

To support cardiovascular health in their feathery friends, bird owners must provide a balanced diet, frequent exercise, and a stress-free environment. In order to identify and treat cardiac issues in birds, routine veterinarian examinations and immediate medical intervention are essential.

You may visit reliable websites like the American Veterinary Medical Association (AVMA) or the Association of Avian Veterinarians (AAV) to learn more about the health and care of birds.

Reasons for Birds’ Unexpected Deaths

Even though they are often praised for their adaptability to many situations and tenacity, birds may nonetheless pass away suddenly. Owners and admirers of birds may take preventative action to guarantee the health and longevity of their feathered companions by being aware of the reasons of unexpected bird death.

Fear and Stress

Stress and fear are two of the main factors that contribute to abrupt avian death. Since birds are very sensitive animals, changes in their habit or surroundings may quickly cause them to become anxious. Birds may have severe terror reactions that result in a heart attack or other deadly reactions in response to loud sounds, abrupt movements, or the presence of predators.

Bird owners need to reduce possible stresses and provide a safe and tranquil environment for their pets.

imbalances in electrolytes

Sudden bird death may also be caused by abnormalities in electrolytes. Electrolytes are necessary for every cell in the body, including the heart, to operate correctly. Electrolyte imbalances may cause problems for a bird’s regular physiological functions, such as heart abnormalities or other health problems.

For the general wellbeing of their bird, bird owners must offer a balanced diet that contains the required minerals and electrolytes.


Toxin exposure is another important factor that contributes to birds dying suddenly. Birds may be poisoned by a variety of home items, plants, and even meals. Lead, zinc, pesticides, and avocados are examples of common poisons.

Because of their highly developed respiratory systems, birds are particularly vulnerable to airborne pollutants. Bird owners must make sure their birds are housed in a safe setting free from exposure to dangerous materials and be aware of any possible threats.

Certain bird species have a genetic predisposition or unique physiological features that make them more vulnerable to heart attacks, according to the American Veterinary Medical Association (AVMA). African Grey Parrots, Cockatoos, and Macaws are some of these species.

Owners of birds should exercise particular caution when it comes to observing the well-being of these species and seek advice from avian vets for routine examinations and preventative treatment.

Risk Factors for Heart Issues in Avian Medicine Obesity

Obesity may pose a serious danger for cardiac issues in birds, just as it does in people. Overweight or obese birds have an increased risk of cardiovascular problems, including heart attacks and heart disease.

Obesity strains the heart and increases the risk of high blood pressure, artery blockages, and other problems. It is crucial for bird owners to keep an eye on their pet’s nutrition and make sure it is being fed a sufficient and well-balanced diet.

To assist avoid obesity in birds, it’s also a good idea to provide them chances for mental and physical activity.

Deficiencies in Vitamins

Deficits in some vitamins may also play a role in the development of cardiac issues in birds. Similar to us, birds need a range of vitamins and minerals to be healthy. Heart muscle weakness and an elevated risk of heart disease may result from deficiency in certain vitamins, including B-complex vitamins and vitamin E.

To avoid vitamin deficiencies, bird owners should make sure their birds are fed a diverse and well-balanced diet that includes fresh fruits and vegetables as well as premium bird food.

The absence of water

Bird heart issues may also be caused by dehydration. To keep hydrated, birds need constant access to clean, fresh water. Dehydration causes a drop in blood volume in birds, which increases cardiac strain.

Blood clot development, abnormal heart rhythms, and other heart-related problems might result from this. It is important for bird owners to make sure their pet’s water dish is consistently supplied with fresh water.

Furthermore, further measures should be taken to avoid bird dehydration during hot weather or times of excessive activity.

Not all birds will be impacted in the same manner by these risk factors, even if they might raise the chance of cardiac issues in birds. Due to the fact that every bird is different, their vulnerability to cardiac problems may also be influenced by other variables including age, genetics, and general health.

It’s usually preferable to speak with a veterinarian that specialises in avian medicine if you’re worried about your bird’s cardiac condition.

Keeping Birds From Developing Heart Issues

Just like us, birds may have cardiac issues. Birds seldom have heart attacks, although they do happen sometimes. Nonetheless, owners of birds may take a few precautions to assist shield their feathery companions from cardiac issues.

Wholesome diet

Keeping up a nutritious diet is one of the most crucial things you can do to keep birds’ hearts healthy. A meal rich in a range of fruits, vegetables, grains, and protein sources should be fed to birds in a balanced manner.

Refrain from giving them meals heavy in sugar, salt, or fat as they might aggravate heart disease. To keep them hydrated, it’s also critical to always have fresh water available.

Don’t give birds too many goodies or items that aren’t in their normal diet. Although it might be tempting to give them human food as a treat, it’s better to stick to treats made especially for birds that have been carefully considered in terms of their nutritional requirements.

Frequent Examinations

Birds should see an avian veterinarian on a regular basis, just as people do. Regular exams may assist in early detection of any underlying medical conditions, such as heart difficulties. The veterinarian will inspect the bird’s heart and listen for any unusual rhythms or noises during these examinations.

To further assess the bird’s cardiac condition, they could also suggest doing other testing, such blood work or X-rays.

Regular checks are essential for the early discovery and treatment of any possible cardiac concerns, since birds are skilled at masking symptoms of sickness. A veterinarian should be seen as soon as possible if you observe any behavioural changes in your bird, such as reduced activity, breathing difficulties, or hunger loss.

Stress-Free Ambience

A bird’s health, especially their heart health, may be adversely affected by stress. Heart issues may be avoided by giving your bird a low-stress environment. This entails giving them plenty of mental and physical stimulation in addition to making sure their cage is roomy and comfy.

Stress levels may also be lowered by regular activity, such as flying or playing with toys safe for birds.

It’s also critical to reduce exposure to possible stressors including loud sounds, abrupt temperature changes, and predator presence. Your bird’s heart health may be greatly preserved by keeping them in a serene atmosphere.

Recall that the best defence against avian cardiac issues is prevention. You can guarantee that your feathery friend’s heart remains robust and healthy by offering a nutritious food, frequent examinations, and a stress-free environment.

A knowledgeable avian veterinarian should be consulted if you have any concerns about the heart health of your bird.

Final Thoughts

Birds’ circulatory systems may get sick and undergo unexpected, deadly cardiac events like heart attacks, even though they are not exactly like those of humans. Their cardiac problems, however, appear differently due to their distinct biochemistry.

Our feathered companions may have long, healthy lives if we are aware of the hazards to their cardiovascular health and take action to minimise them.
