Early improvement in left ventricular diastolic function after relief of chronic right ventricular pressure overload.
Chronic right ventricular pressure overload is associated with left ventricular diastolic dysfunction. Whether or not an abrupt reduction in pulmonary artery pressure in patients with chronic pulmonary hypertension results in early improvement of left ventricular diastolic function is unknown. To assess this, the Doppler indexes of left ventricular diastolic function and echocardiographic measu...
متن کاملDiastolic Left Ventricular Pressure-Volume Relationship before and after Chronic Right Ventricular Pressure Overload in Dogs without Pericardia
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure 27...

متن کاملImprovement of diastolic function after regression of left ventricular hypertrophy.
OBJECTIVE To evaluate the diastolic function after regression of left ventricular hypertrophy, in mild to moderate hypertension treated with angiotensin converting enzyme(ACE) inhibitor and, if necessary, with a diuretic. METHODS Ninety-eight hypertensive patients with left ventricular hypertrophy (LVH) and abnormal left ventricle diastolic function indexes received captopril (Capotena) 50 to...
متن کاملRight ventricular diastolic function in canine models of pressure overload, volume overload, and ischemia.
By limiting filling, abnormalities of right ventricular (RV) diastolic function may impair systolic function and affect adaptation to disease. To quantify diastolic RV pressure-volume relations and myocardial compliance (MC), a new sigmoidal model was developed. RV micromanometric and sonomicrometric data in alert dogs at control (n = 16) and under surgically induced subacute (2-5 wk) RV pressu...
