Diastolic left ventricular functional indices: Comparison between gated myocardial perfusion SPECT and echocardiography
Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...
متن کاملThe influence of Asthma on Right Ventricular Systolic and Diastolic Function in Children according to Tissue Doppler Echocardiography
Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...
متن کاملDiastolic time during static and dynamic exercise in myocardial infarction.
To evaluate the difference in the response of DT in the early phase of static (sustained weight load) and dynamic (treadmill) exercise, the relation of DT and HR was studied by ear densitography in 11 patients with myocardial infarction. None of the patients had an ischemic electrocardiographic response during exercise. Despite an increase in HR and the pressure-HR product with both types of ex...
متن کاملSystolic and diastolic abnormalities reduce the cardiac response to exercise in adolescents with type 2 diabetes.
OBJECTIVE To better understand the cardiac limitations during exercise in adolescents with type 2 diabetes mellitus (T2DM), we measured left ventricular performance with magnetic resonance imaging (MRI) during exercise in diabetic and nondiabetic adolescents. RESEARCH DESIGN AND METHODS Thirteen subjects with T2DM, 27 overweight/obese nondiabetic (ObeseND) subjects, and 19 nondiabetic nonobes...
متن کاملAbsence of diastolic mitral annular oscillations is a marker for relaxation-related diastolic dysfunction.
Although Doppler tissue imaging frequently indicates the presence of mitral annular oscillations (MAO) following the E' wave (E'' wave, etc.), only recently was it shown that annular "ringing" follows the rules of damped harmonic oscillatory motion. Oscillatory model-based analysis of E' and E'' waves provides longitudinal left ventricular (LV) stiffness (k'), relaxation/viscoelasticity (c'), a...
