Modulating 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 کاملacute and chronic effect of cigarette on right and left ventricular diastolic function
conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...
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 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...
متن کاملAnalysis 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...
