| pubmed-article:8790034 | pubmed:abstractText | In myotonic dystrophy (DM), striated muscle is involved in relation to the size of the DNA mutation. Smooth muscle may be similarly impaired at the level of the urinary and digestive apparatus and possibly at the level of small vessels, since microangiopathy has been described in the iris and digital capillaries. Our purpose was to study the function of the myocardial microvasculature in relation to the size of the mutation in DM patients without clinical cardiac involvement and with normal left ventricular dimensions and function and normal large coronary arteries. | lld:pubmed |
