Properties of Myocardium in Cardiomegaly

Properties of myocardium in cardiomegaly.

• The ventricular myocardium responds to a chronic increased work load by an increase in the myocardial mass. The functional significance of this adaptation has been an area of interest particularly because of the common clinical finding of an increased cardiac mass in cardiac failure. Since an increased myocardial mass is predominantly the result of the enlargement rather than the multiplicati...

Cardiomegaly in tropical Africa.

The term "cardiomegaly" is found in 5-7% of chest X-ray film evaluations in tropical Africa. However, "cardiomegaly" is a descriptive term, devoid of any aetiological meaning. Therefore, providing information about the aetiological factors leading to heart enlargement in a group of Africans (Nigerians) was the purpose of this study. In the years 2002-2011, 170 subjects (aged 17-80 years, mean a...

[Familial cardiomegaly].

In 1949 William Evans gave the name of familial cardiomegaly to what he believed to be a "distinct syndrome having a definite clinical, cardiographic, and pathological pattern." The essential features were the familial incidence of cardiomegaly without obvious cause and a marked tendency to arrhythmia and heart block with associated palpitation, giddiness, and syncope. Death may be sudden or ra...
