A microscope image of myocarditis at autopsy in a person with acute onset of heart failure. The black dots are primarily lymphocytes infiltrating the myocardium. Specialty: Infectious disease, cardiology: Symptoms: Shortness of breath, chest pain, decreased ability to exercise, irregular heartbeat [1] Complications
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to an antigen. [ 1 ] [ 2 ] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity .
"The esophagus has muscle in it, and if that muscle starts spasming, that can cause chest pain," Martin explains. In fact, "the symptoms are very difficult to differentiate from heart disease ...
The original method of diagnosing rheumatic heart disease was through heart auscultation, specifically listening for the sound of blood regurgitation from possibly dysfunctional valves. However, studies have shown that echocardiography is much more efficient in detecting RHD due to its high sensitivity.
Allergic ACS is a syndrome involving two components. One component is immune-mediated resulting in hypersensitivity, allergy, and an anaphylactic or anaphylactoid reaction. The second component involves cardiac signs and symptoms seen with acute coronary syndrome (ACS). Cardiac symptoms vary depending on the type of variant the patient presents ...
Amplified musculoskeletal pain syndrome (AMPS) is an illness characterized by notable pain intensity without an identifiable physical cause. [1] [6] Characteristic symptoms include skin sensitivity to light touch, also known as allodynia. Associated symptoms may include changes associated with disuse including changes in skin texture, color ...
Eosinophilic myocarditis is inflammation in the heart muscle that is caused by the infiltration and destructive activity of a type of white blood cell, the eosinophil. Typically, the disorder is associated with hypereosinophilia, i.e. an eosinophil blood cell count greater than 1,500 per microliter (normal 100 to 400 per microliter).
