Arterial compliance abnormalities in isolated systolic hypertension.
Arterial compliance measurements using intraarterial pulse contour analysis and a modified Windkessel model were carried out in 19 patients with isolated systolic hypertension (> or = 160/< or = 90 mm Hg) and compared to measurements in 29 patients with essential hypertension (diastolic blood pressure [BP] > or = 95 mm Hg) and 47 normotensive control subjects. Arterial capacitive compliance was...
متن کاملSubclinical LV Dysfunction Detection Using Speckle Tracking Echocardiography in Hypertensive Patients with Preserved LV Ejection Fraction
BACKGROUND Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. METHODS We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fract...
متن کاملDetection of subclinical LV dysfunction by tissue Doppler imaging.
Echocardiography is a well-established clinical tool for the assessment of myocardial function. However, in subclinical diseases, the routinely used echocardiographic parameters such as left ventricular (LV) ejection fraction (EF) and fractional shortening are not sensitive enough to detect myocardial dysfunction. We have learned over the past years that other echocardiographic techniques such ...
متن کاملSubclinical left ventricular systolic dysfunction in patients with severe aortic stenosis: A speckle-tracking echocardiography study.
OBJECTIVE In patients with aortic stenosis (AS), the left ventricular (LV) geometry changes due to the increased LV afterload. However, subclinical myocardial dysfunction can develop despite a normal LV ejection fraction (EF). This study was an investigation of subclinical LV systolic dysfunction in patients with severe AS with a normal LV EF using a strain imaging method, speckle-tracking echo...
متن کاملSystemic arterial compliance, systemic vascular resistance, and effective arterial elastance during exercise in endurance-trained men.
Systemic arterial compliance (C) and vascular resistance (R) regulate effective arterial elastance (Ea), an index of artery load. Increases in Ea during exercise are due primarily to reductions of C and maintain optimal ventricular-arterial coupling. Because C at rest and left ventricular functional reserve are greater in endurance-trained (ET) compared with sedentary control (SC) humans, we hy...
