Left Ventricular Systolic and Diastolic Function in Obstructive Sleep Apnea

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...

Left Ventricular Systolic and Diastolic Function in Obstructive Sleep Apnea: Impact of Continuous Positive Airway Pressure Therapy Running title: Butt et al.; Echocardiography in obstructive sleep apnea

Left ventricular systolic and diastolic function in obstructive sleep apnea: impact of continuous positive airway pressure therapy.

BACKGROUND Previous studies in obstructive sleep apnea (OSA) were limited by study cohorts with comorbidities that confound assessment of left ventricular (LV) systolic and diastolic function. We comprehensively evaluated LV function using 2-dimensional echocardiography (2DE), tissue Doppler imaging (TDI), and 3-dimensional echocardiography (3DE) in subjects moderate-severe OSA, who were compar...

Left ventricular diastolic dysfunction is linked to severity of obstructive sleep apnea Running head: diastole and sleep apnea

Word count: 199) Background Obstructive sleep apnea has been related to increased cardiovascular risk. The present study examined the relationships between respiratory parameters and left ventricular abnormalities in obstructive sleep apnea. Patients/Methods One hundred and fifty newly diagnosed OSA patients without any known cardiovascular disease were included (age = 49±11 years, BMI = 27.1±3...

Impact of Obstructive Sleep Apnea and Snoring on Left Ventricular Mass and Diastolic Function in Hypertensive Nigerians

BACKGROUND Systemic hypertension (HTN) and obstructive sleep apnea (OSA) are individually associated with left ventricular structural and functional adaptations. However, little is known about the impact of OSA on the left ventricle in Africans with HTN. AIM The aim of this study is to determine the association between OSA and left ventricular mass (LVM) and diastolic dysfunction in Nigerian ...
