LEFT 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 کاملLeft ventricular diastolic capacity in man.
Plasma volume expansion with 500 ml of low-molecular-weight dextran was used in 27 patients (nine normal subjects, 13 patients with ischemic heart disease, four with aortic stenosis and one with cardiomyopathy) to increase left ventricular end-diastolic pressure (LVEDP) from a control value of 12.4 +/- 7.0 mm Hg (mean +/- SD) to 23.3 +/- 7.0 mm Hg and end-diastolic volume (EDV) from 84.0 +/- 23...
متن کاملInfluence of exercise training on left ventricular diastolic function and its relationship to exercise capacity in patients after myocardial infarction.
BACKGROUND The study's aim was to examine the effect of exercise training on left ventricular diastolic function (LVDF) and whether LVDF could predict an improvement in exercise capacity (EC) in post-myocardial infarction patients. METHODS Forty-eight males, aged 56.4 +/- 7.2 years, with preserved left ventricular systolic function (LVSF) and mild diastolic dysfunction (the ratio of transmitr...
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 کاملDiastolic heart failure, diastolic left ventricular dysfunction and exercise intolerance.
The phenomenon of “diastolic heart failure” is rightly receiving greater attention (1–4); community-based studies such as those in Framingham (5) and Olmsted County (6) show that up to 50% of older persons with heart failure do not have impaired left ventricular (LV) systolic function to account for this, and that the condition is usually associated with LV hypertrophy and is preceded by elevat...
