Many affected people will eventually become unable to walk [2] and Duchenne muscular dystrophy in particular is associated with shortened life expectancy. Muscular dystrophy was first described in the 1830s by Charles Bell. [2] The word "dystrophy" comes from the Greek dys, meaning "no, un-" and troph-meaning "nourish". [2]
Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name , FSHD tends to sequentially weaken the muscles of the face , those that position the scapula , and those overlying the humerus bone of the upper arm.
There are more women than men with hypertension, [19] and, although men develop hypertension earlier in life, [20] hypertension in women is less well controlled. [21] [22] The consequences of high blood pressure in women are a major public health problem and hypertension is a more important contributory factor in heart attacks in women than men ...
Muscular dystrophy; Tuberculosis: 1 to 2% of TB cases. [18] Autoimmune mechanisms [19] Thiamine deficiency; Recent studies have shown that those subjects with an extremely high occurrence (several thousands a day) of premature ventricular contractions (extrasystole) can develop dilated cardiomyopathy. In these cases, if the extrasystole are ...
Myotonic dystrophy (DM) is a type of muscular dystrophy, a group of genetic disorders that cause progressive muscle loss and weakness. [1] In DM, muscles are often unable to relax after contraction. [1] Other manifestations may include cataracts, intellectual disability and heart conduction problems.
Patients with diastolic heart failure have a preserved ejection fraction, which is a measure of systolic function. [33] [34] Diastolic dysfunction is an early consequence of hypertension-related heart disease and is exacerbated by left ventricular hypertrophy [20] [34] and ischemia.
Duchenne muscular dystrophy is the most common type of muscular dystrophy, [3] with a median life expectancy of 27–31 years. [5] [11] However, with comprehensive care, some individuals may live into their 30s or 40s. [3] Duchenne muscular dystrophy is considerably rarer in females, occurring in approximately one in 50,000,000 live female ...
The myocardium is dilated, reducing the systolic pump of the ventricles. For this reason, most patients have left myocardial thickening (hypertrophy). While cardiomyopathy can be life-threatening, it is commonly resolved or substantially improved in Barth Syndrome patients after puberty. [10]
