Analysis of left ventricular diastolic function.
Our understanding of left ventricular diastolic function has evolved with our understanding of Doppler echocardiographic assessment of left ventricular filling dynamics. Left ventricular diastolic function consists of several variables which affect the Doppler echocardiographic recordings in a complex way. While there are still limitations with the non-invasive assessment of left ventricular di...
متن کاملModulating Left Ventricular Diastolic Function
Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the elevation in LV filling pressure observed with dopamine, we administered incremental infusi...
متن کاملLEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...
متن کامل[Analysis of left ventricular diastolic function using magnetic resonance imaging].
Heart failure is not always due to an alteration in systolic function, and a diastolic dysfunction could explain many cases of heart failure with a normal systolic function. Diastolic function depends on the left ventricular filling capacity to ensure a normal stroke volume. It is routinely measured with transthoracic echocardiography, as it is an easily accessible non-invasive test. The MRI, u...
متن کاملEchocardiographic Evaluation of Left Ventricular Diastolic Function
Approximately half of patients with a diagnosis of heart failure have a normal left ventricular (LV) ejection fraction (EF) without valve disease which is defined as diastolic heart failure (DHF), because it is attributed to LV diastolic dysfunction.[2] Studies examining prevalence of diastolic heart failure in hospitalized patients or in patients undergoing outpatient diag‐ nostic screening an...
