once again thank you so much for your input...im still waiting for the results of the echo.....hope your feeeling well..again thank you!
High blood pressure (sustained) will overwork the heart, and an overworked heart will compensate by enlarging the left ventricle (increase volume), and not properly treated will enlarge to a degree that will reduce contractility and increase blood volume. Other than too much blood volume in the heart as a cause, narrowed valves in the heart (mitral valve), increased heart pressures, increased heart stiffness, primary myocardial diseases (viral, drugs, some medication, alcohol, etc.) or myopathies, etc..
A leaking valve if severe can cause a reduction in cardiac output and the result is an overworked heart and eventually enlarged chambers. A narrow orifice (stenosis of mitral valve) can directly increase arterial pressure and enlarge the atrium...leaky valve doubtful without symptoms of heart failure.
