Left ventricular systolic performance in asymptomatic aortic stenosis

Left ventricular systolic and diastolic function assessed by tissue Doppler imaging and outcome in asymptomatic aortic stenosis.

AIMS Left ventricular (LV) hypertrophy and abnormal non-invasive measures of LV diastolic function are common in patients with severe aortic stenosis (AS) but their prognostic importance is uncertain. This study aimed to determine whether tissue Doppler measures of LV systolic and/or diastolic function or echocardiographic LV hypertrophy are useful for risk stratifying asymptomatic patients wit...

Exercise-induced changes in left ventricular global longitudinal strain in asymptomatic severe aortic stenosis.

BACKGROUND The management of patients with asymptomatic severe aortic stenosis (ASAS) is still under discussion. Therefore, it is advisable to search for the parameters of early damage to left ventricular (LV) function. AIM The aim of the study was to assess exercise-induced changes in LV global longitudinal strain (GLS) in ASAS. METHODS The ASAS group consisted of 50 patients (26 women and...

Left Ventricular Systolic Dysfunction in Asymptomatic Black Hypertensive Subjects.

BACKGROUND Hypertension has been established as one of the commonest causes of heart failure especially in sub-Saharan Africa. We have previously observed a high prevalence of left ventricular (LV) systolic dysfunction in hypertensive heart failure patients in Nigeria despite a low prevalence of ischemic heart disease. The present study was, therefore, undertaken to assess the prevalence of asy...

Effect of heart irregularity on left ventricular and arterial peak systolic pressures in aortic stenosis.

Assessment of left ventricular systolic function in aortic stenosis and prognostic implications.

Left ventricular (LV) ejection fraction, most commonly assessed with two-dimensional echocardiography, is an important prognostic determinant of many cardiovascular diseases. The decision of implanting specific cardiovascular devices, such as cardiac resynchronization therapy or implantable cardioverter defibrillator, recommending valvular surgery or chemotherapy relies on the LV ejection fract...
