Left atrial to left ventricular end diastolic diameter ratio in left ventricular diastolic dysfunction

ABSTRACT

Background: Diastolic dysfunction [DD] is difficult to diagnose and characterize despite many techniques. It is known that left atrial diameter [LAD] increases and left ventricular internal end diastolic diameter [LVIDD] remains the same in moderate to severe diastolic dysfunction [grade II and above] but a ratio between these two [LAD/LVIDD] has never been used to assess diastolic dysfunction. This study aims to analyze the relationship between the ratio, left atrial diameter/ left ventricular internal end diastolic diameter [LAD/LVIDD] and diastolic dysfunction [grade II and above]. This study also aims to give a statistical model based upon this relationship that is able to help in diagnosing diastolic dysfunction
