Damage to skeletal muscle may take various forms. Crush and other physical injuries cause damage to muscle cells directly or interfere with blood supply, while non-physical causes interfere with muscle cell metabolism. When damaged, muscle tissue rapidly fills with fluid from the bloodstream, including sodium ions.
Exertional rhabdomyolysis, the exercise-induced muscle breakdown that results in muscle pain/soreness, is commonly diagnosed using the urine myoglobin test accompanied by high levels of creatine kinase (CK). Myoglobin is the protein released into the bloodstream when skeletal muscle is broken down. The urine test simply examines whether ...
Myoglobinuria pathophysiology consists of a series of metabolic actions in which damage to muscle cells affect calcium mechanisms, thereby increasing free ionized calcium in the cytoplasm of the myocytes (concurrently decreasing free ionized calcium in the bloodstream). This, in turn, affects several intracellular enzymes that are calcium ...
Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
Other conditions that directly or indirectly lead to heart muscle damage and death can also increase troponin levels, such as kidney failure. [ 18 ] [ 19 ] Severe tachycardia (for example due to supraventricular tachycardia ) in an individual with normal coronary arteries can also lead to increased troponins for example, it is presumed due to ...
Trendelenburg's sign is found in people with weak or paralyzed abductor muscles of the hip, namely gluteus medius and gluteus minimus. [1] It is named after the German surgeon Friedrich Trendelenburg. It is often incorrectly referenced as the Trendelenburg test which is a test for vascular insufficiency in the lower extremities.
Supplemental tests: blood tests, exercise stress test, 12-minute Walk Test, non-ischemic forearm test, EMG Glycogen storage disease type V ( GSD5 , GSD-V ), [ 1 ] also known as McArdle's disease , [ 2 ] is a metabolic disorder , one of the metabolic myopathies , more specifically a muscle glycogen storage disease , caused by a deficiency of ...
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
