What is cardiac anaphylaxis?
Cardiac anaphylaxis refers to the functional and metabolic changes in the heart caused by the anaphylactic release of histamine and vasoactive products of arachidonic acid cascade by mast cells and basophils.
What are the 8 signs and symptoms of allergic reactions and anaphylaxis?
Some symptoms include:
- Skin rashes and itching and hives.
- Swelling of the lips, tongue or throat.
- Shortness of breath, trouble breathing, wheezing (whistling sound during breathing)
- Dizziness and/or fainting.
- Stomach pain, vomiting or diarrhea.
- Feeling like something awful is about to happen.
What are the cardiovascular effects of anaphylactic shock?
Cardiovascular manifestations of anaphylaxis include hypotension and shock, cardiac arrhythmias, ventricular dysfunction and cardiac arrest [7].
What happens to the heart during anaphylaxis?
During anaphylaxis, coronary hypoperfusion caused by systemic vasodilation, plasma leakage, loss of volume due to increased vascular permeability and reduced venous return can contribute to cardiac output suppression, leading further (33) to myocardial damage and ventricular dysfunction.
Why does heart rate increase in anaphylaxis?
During anaphylaxis, small blood vessels (capillaries) begin to leak blood into your tissues. This can cause a sudden and dramatic drop in blood pressure. Other symptoms include a rapid or weak pulse and heart palpitations.
Can anaphylaxis cause circulatory collapse?
Anaphylaxis is a severe, systemic allergic reaction characterized by multisystem involvement, including the skin, airway, vascular system, and gastrointestinal tract. Severe cases may result in complete obstruction of the airway, cardiovascular collapse, and death.
What are the 4 most common symptoms of anaphylaxis?
Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock — blood pressure drops suddenly and the airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
What are the 7 main symptoms of an allergic reaction?
Common symptoms of an allergic reaction include:
- sneezing and an itchy, runny or blocked nose (allergic rhinitis)
- itchy, red, watering eyes (conjunctivitis)
- wheezing, chest tightness, shortness of breath and a cough.
- a raised, itchy, red rash (hives)

Does anaphylaxis cause cardiogenic shock?
[9] Severe anaphylactic reactions with cardiogenic shock are rare and only 2 additional cases have been reported[6,10] since the publication of Averin et al.
What is anaphylaxis and what are the symptoms?
Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock — blood pressure drops suddenly and the airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting. Common triggers include certain foods, some medications, insect venom and latex.
What are the signs of anaphylactic shock?
Anaphylactic shock often includes shortness of breath. A person doesn’t always have trouble breathing, but if the symptom is present, it’s a good indicator that the allergic reaction is turning into anaphylaxis. These are the telltale signs to look for: Unable to speak more than one or two words.
What happens if anaphylaxis is not treated?
If anaphylaxis isn’t treated right away, it can be fatal. Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. Sometimes, however, it can occur a half-hour or longer after exposure. Signs and symptoms include: Skin reactions, including hives and itching and flushed or pale skin
What are the cardiac risks of anaphylaxis?
A myocardial infarction or atrial fibrillation can develop during anaphylaxis, and these cardiac risks are greater in patients over the age of 50. Epinephrine is the drug of choice to treat anaphylaxis, but it carries a risk of overdose and of triggering cardiovascular complications.
