In medicine, myopathy is a disease of the muscle [1] in which the muscle fibers do not function properly. Myopathy means muscle disease ( Greek : myo- muscle + patheia -pathy : suffering ). This meaning implies that the primary defect is within the muscle, as opposed to the nerves (" neuropathies " or " neurogenic " disorders) or elsewhere (e.g ...
This person was eventually diagnosed with tachycardia-induced cardiomyopathy. [7] There are no specific diagnostic criteria for TIC, and it can be difficult to diagnose for a number of reasons. First, in patients presenting with both tachycardia and cardiomyopathy, it can be difficult to distinguish which is the causative agent. [5]
Transient apical ballooning syndrome or takotsubo cardiomyopathy is found in 1.7–2.2% of patients presenting with acute coronary syndrome. [1] While the original case studies reported on individuals in Japan, takotsubo cardiomyopathy has been noted more recently in the United States and Western Europe.
Inclusion body myopathy with early-onset Paget disease and frontotemporal dementia (IBMPFD), now more commonly referred to as multisystem proteinopathy (MSP), is an autosomal dominant condition caused by mutations in VCP, HNRPA2B1 or HNRNPA1; it is a multisystem degenerative disorder that can affect muscle, bone, and/or the central nervous system.
Although idiopathic inflammatory myopathy (IIM) is a diagnosis of exclusion, it is often the initial misdiagnosis of several acquired non-inflammatory myopathies. [1] [9] [10] This is due to a number of factors, including: overlapping symptoms (such as muscle weakness, pain, elevated CK);
Alcoholic cardiomyopathy (ACM) is a disease in which the long-term consumption of alcohol leads to heart failure. [1] ACM is a type of dilated cardiomyopathy. The heart is unable to pump blood efficiently, leading to heart failure. It can affect other parts of the body if the heart failure is severe.
Bethlem myopathy 1 is a rare disease, affecting about 1 in 200,000 people. [8] Bethlem myopathy 2 is an ultra-rare disease, affecting less than 1 in 1,000,000 people. [9] The condition was described by J. Bethlem and G. K. van Wijngaarden in 1976. [10]
Centronuclear myopathy manifests on muscle biopsy as centrally located nuclei encircled by a perinuclear halo filled with aggregates of glycogen and mitochondria but without myofilaments. [10] All muscles, including extra-ocular muscles, have the distinctive central nucleus, [ 11 ] which can affect up to 90% of the fibers.
