NCI: Hypertrophy associated with both hypertension and obstruction to ventricular outflow leads to pathologic cardiac growth and it is associated with increase morbidity and mortality. Symptomatic ventricular disease takes a growing toll on the health of nations. As other cardiovascular diseases such as stroke and myocardial infarction are in decline as causes of mortality, the heart failure problem becomes increasingly urgent. Congenital heart defects occur in 1% of live births and fetal heart malformations are implicated in many pregnancies that end in still-birth or spontaneous abortion. The current paradigm suggests that the heart adapts to excess of hemodynamic loading by compensatory hypertrophy, which under condition of persistent stress, over time evolves into dysfunction and myocardial failure. There is considerable evidence that direct effects of increased mechanical stress are sensed within the ventricular wall and that signal is critical for the generation of growth responses. Despite compelling s
