“…20,21 Loading conditions, heart rate, and age significantly affect the individual time intervals in MPI. 22,23 However, previous studies have shown that MPI is less affected by age and by changes in heart rate and preload than are conventional Doppler measurements. 9,10,21 Therefore the index needs no correction for blood pressure, heart rate, or age.…”

“…The frame rate for tissue Doppler (TDI) measurements was >100/s. Transmitral pw-Doppler inflow at the tips of the mitral leaflets was measured to obtain E wave velocity, E wave deceleration time (DT), A wave velocity and E/A ratio [12]. Average peak early diastolic velocity (E´) was obtained from the septal and lateral sides of the mitral annulus in the apical four-chamber view with proper pulsed-wave TDI settings.…”

Background/Aims: Cardiac changes observed in chronic kidney disease patients are of multifactorial origin including chronic uremia, hemodynamics or inflammation. Restoration of renal function by kidney transplantation (KTX) may reverse cardiac changes. Novel echocardiographic methods such as speckle tracking echocardiography (STE) allow early and sensitive detection of subtle changes of cardiac parameters. We evaluated changes of cardiac structure and function after KTX by advanced echocardiographic modalities. Methods: Thirty-one KTX recipients (female n=11) were evaluated by medical examination, laboratory testing and echocardiography before and after KTX (median follow-up 19 months). Left ventricular (LV) and right ventricular (RV) diameters and function were assessed by echocardiographic standard parameters. Longitudinal 2D strain of the LV (GLPS) and left atrium (LA) was determined by 2D STE. Results: After KTX, median serum creatinine level was 1.3 mg/dl (IQR, 1.2-1.5). Systolic blood pressure decreased significantly after KTX. Echocardiography showed a significant reduction in LV end-diastolic septal and posterior wall thickness and LV mass index after KTX, which was accompanied by an improvement of GLPS. There were no relevant changes in parameters of LA (reservoir, conduit or contractile) function, LV diastolic or RV function after KTX. Conclusion: LV hypertrophy reversed after successful KTX and was accompanied by an improvement in longitudinal LV function as assessed by STE. Diastolic function and STE-derived LA function parameters did not change significantly after KTX.

“…However, these measurements have been limited by load dependence and are dependent upon age, location of Doppler sample volume, rhythm and heart rate. [27][28][29] TDE is a newly developed echocardiography technique that provides more quantitative information on regional and global myocardial functions compared to standard echocardiographic methods. 7 It is influenced only partially by the changes in preload, cardiac rhythm and left atrial pressure, and allows the measurement of myocardial velocities and time intervals in the same cycle.…”

enopause is a critical period in a woman's life, during which many physiologic and pathologic changes occur. Women spend one-third of their lifetime in this period and the hormonal changes that occur during this period have significant influences on several organs and systems. The cardiovascular system is among the most dramatically affected systems. Changes in cardiovascular risk factors due to estrogen deficiency and subsequent increase in cardiovascular morbidity and mortality have been demonstrated in several studies. [1][2][3] Structural and functional changes in the heart can also occur during the postmenopausal period. The effects of menopause on cardiac structure and function have not been investigated adequately. Interpretation of the results of the few previous studies 4-6 comparing pre-and postmenopausal women comprises some difficulties, owing to significant age differences and small sample sizes. Moreover, cardiac functions have been evaluated only by conventional 2-dimensional (D) and M-mode echocardiography in these studies, thus the extent of influence on more recent echocardiographic parameters after menopause have not been adequately analyzed.Tissue Doppler echocardiography (TDE) is a relatively new technique, which is partially utilized in recent years to evaluate cardiac functions via measurement of myocardial velocities. 7 Also, myocardial performance index (MPI) has been recognized as a parameter that reflects ventricular systolic and diastolic functions. 8,9 To our knowledge, no literature exists on how myocardial velocities, as measured by TDE, which have some advantages over standard echocardiographic methods, and MPI, which provides a more quantitative and global evaluation of left ventricular (LV), are affected by menopause. The present study was designed to investigate how myocardial velocities measured by TDE and MPI, which together provide more quantitative data on regional and global ventricular functions, are affected by menopause. Methods Study PopulationSubjects were selected from healthy women admitted to the gynecology and obstetrics, and cardiology outpatient departments between 2001 and 2006. After informed consent was obtained, a prospective analysis was performed. Body weight and height of all subjects were measured and body mass index was calculated. Fasting blood samples were drawn for biochemical and hematological investigations and ECGs were done. An exercise stress test using Bruce protocol and subsequent echocardiographic evaluations were performed. Postmenopausal status was confirmed as being in menopause for at least 12 months with serum follicle-stimulating hormone (FSH) levels of >30 mU/ml and estrogen levels of <20 pg/ml, and premenopausal status Effects of Menopause on the Myocardial Velocities and Myocardial Performance IndexMehmet Akif Düzenli, MD; Kurtulus Ozdemir, MD; Abdullah Sokmen, MD**; Ahmet Soylu, MD; Nazif Aygul, MD; Kazim Gezginc, MD*; Mehmet Tokac, MD Background Although menopause is known to increase cardiovascular risk and mortality, the effect ...
