acute 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 کاملDetermination of the Effects of Digoxin on the Right Ventricular Function in Patients Undergoing Pneumonectomy
Introduction: Pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. We have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. Materials a...
متن کاملEffects of chronic right ventricular volume and pressure loading on left ventricular performance.
The effects of chronic right ventricular (RV) distension on left ventricular (LV) funiction were assessed in dogs 3 weeks after pressure and volume loading of the RV lhad been produced by the emplacement of a constricting band around the pulmonary artery and the creation of tricuspid insufficiency. This resulted in ascites, RV hypertrophy and dilatation, an increase in RV end-diastolic pressure...
متن کاملEarly 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 کاملAcute right ventricular pressure overload compromises left ventricular function by altering septal strain and rotation.
While right ventricular (RV) dysfunction has long been known to affect the performance of left ventricle (LV), the mechanisms remain poorly defined. Recently, speckle-tracking echocardiography has demonstrated that preservation of strain and rotational dynamics is crucial to both LV systolic and diastolic function. We hypothesized that alteration in septal strain and rotational dynamics of the ...
