PURPOSE: To find out how resistin and leptin levels were affected in patients with acromegaly and whether there is a relation between resistin levels and cardiac parameters. We also aimed to investigate whether resistin and leptin may be a link between insulin resistance and cardiac functions as well as these affected cardiac functions in the patients with acromegaly. METHODS: We included 30 subjects (15 men and 15 women) who had a diagnosis of acromegaly and 30 healthy (10 men and 20 women) subjects...

Diastolic heart failure, also known as heart failure with preserved left ventricular ejection fraction (HF-pEF), is responsible for approximately 50 % of all heart failure cases. According to current guidelines the diagnosis HF-pEF requires three criteria: (1) signs or symptoms of heart failure, (2) presence of a normal left ventricular ejection fraction and (3) evidence of diastolic dysfunction. Echocardiography is the diagnostic modality of choice, especially after ruling out other causes of dyspnea, such as pulmonary diseases, heart rhythm disturbances and volume overload...

Experimental studies implicate late systolic load as a determinant of impaired left-ventricular relaxation. We aimed to assess the relationship between the myocardial loading sequence and left-ventricular contraction and relaxation. Time-resolved central pressure and time-resolved left-ventricular geometry were measured with carotid tonometry and speckle-tracking echocardiography, respectively, for computation of time-resolved ejection-phase myocardial wall stress (EP-MWS) among 1214 middle-aged adults without manifest cardiovascular disease from the general population...

BACKGROUND: Conventional Doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (LVEDP). However, these parameters have limitations in predicting LVEDP among patients with mitral regurgitation. This study sought to establish whether the correlation between measurements derived from tissue Doppler echocardiography and LVEDP remains valid in the setting of severe mitral regurgitation. METHODS: THIRTY PATIENTS (MEAN AGE: 57...

Doppler ultrasound measures of left ventricular (LV) active relaxation and diastolic suction are slowed with healthy aging. It is unclear to what extent these changes are related to alterations in intrinsic LV properties and/or cardiovascular loading conditions. Seventy carefully screened individuals (38 female, 32 male) aged 21-77 were recruited into four age groups (young: <35; early middle age: 35-49; late middle age: 50-64 and seniors: ≥65 yr). Pulmonary capillary wedge pressure (PCWP), stroke volume, LV end-diastolic volume, and Doppler measures of LV diastolic filling were collected at multiple loading conditions, including supine baseline, lower body negative pressure to reduce LV filling, and saline infusion to increase LV filling...

PURPOSE: To investigate the diagnostic performance of Doppler echocardiography (DE) in predicting the outcome of weaning from mechanical ventilation in patients without overt cardiac disease. METHODS: Fifty critical care noncardiac patients who fulfilled predetermined criteria for weaning underwent DE before and at the end of spontaneous breathing trial (pre-SBT/end-SBT, respectively). "Conventional" mitral inflow analysis and "advanced" DE parameters [tissue Doppler imaging (TDI)-derived mitral/tricuspid annular velocities and color M-mode Doppler velocity of propagation (V p)] were used to assess left ventricular (LV) diastolic function/filling pressures...

BACKGROUND: The aim of this study was to demonstrate improvement in the characterization of diastolic function in the routine practice of a clinical echocardiography laboratory after the implementation of a quality improvement initiative. The echocardiographic analysis of left ventricular (LV) diastolic dysfunction is an inherently complex process involving the integration of multiple indices for accurate assessment.

AIM: This study aimed at evaluating the early effects of successful elective percutaneous coronary intervention (PCI) on systolic and diastolic function. METHODS: We consecutively studied the systolic and diastolic function in 21 patients with stable coronary artery disease (CAD) and left ventricular ejection fraction (LVEF) > 40% before and 48 hours after successful elective PCI. RESULTS: Tei index and systolic indices (LVEF, regional wall motion abnormality score, tricuspid annular plane systolic excursion and peak systolic velocity of mitral and tricuspid annulus) did not change significantly...

Epidemiologic data show that diastolic heart failure is responsible for 38% to 54% of all heart failure cases. Left ventricular diastolic function can be characterized invasively in the catheter laboratory and non-invasively by echocardiography. Although echocardiography does not directly measure hemodynamic parameters, it is the most practical routine clinical approach for the evaluation of left ventricular diastolic function with given clinical and experimental evidence supporting its use as well as its safety, versatility, and portability...

BACKGROUND: Prior studies demonstrating the prognostic value of echocardiographic measures of diastolic function have been limited by sample size, have included only select clinical populations, and have not incorporated newer measures of diastolic function nor determined their independent prognostic value. The objective of this study is to determine the independent prognostic value of established and new echocardiographic parameters of diastolic function. METHODS: We included 3,604 consecutive patients referred to 1 of 3 echocardiography laboratories over a 2-year period...

Diastolic heart failure is increasing in prevalence. Although the pathophysiology is incompletely understood and current therapeutic strategies are limited, identification of diastolic dysfunction is important. We review the role of contemporary techniques with echocardiography and cardiac magnetic resonance imaging (CMRI) in the assessment of diastolic dysfunction. Cardiac catheterization is the criterion standard for demonstrating impaired relaxation and filling by making direct measurements; however, echocardiography has replaced it as the most clinically used tool...

BACKGROUND: Congestive heart failure in the setting of a preserved left ventricular (LV) ejection fraction is increasing in prevalence among the senior population. The underlying pathophysiologic abnormalities in ventricular function and structure remain unclear for this disorder. We hypothesized that patients with heart failure with preserved ejection fraction (HFPEF) would have marked abnormalities in LV diastolic function with increased static diastolic stiffness and slowed myocardial relaxation compared with age-matched healthy controls...

AIMS: Cardiac resynchronization therapy (CRT) improves systolic function in heart failure (HF). However, the effects of CRT on left ventricular (LV) diastolic function are not fully understood. The aim of this study was to determine clinical and echocardiographic correlates of improvement in LV diastolic function after CRT. METHODS AND RESULTS: Fifty-four patients (mean age, 61.9 +/- 10.5; 43 men; mean LV ejection fraction 24.6 +/- 4.0%) with severe HF were enrolled in the study...

Echocardiography is the cornerstone for the assessment of left ventricular diastolic function in routine clinical practice. The technique can provide a comprehensive evaluation of left ventricular structure and function in patients with normal and depressed ejection fraction. Aside from two-dimensional imaging, Doppler measurements include mitral inflow, pulmonary venous flow, flow propagation velocity, and tissue Doppler imaging. Using recently published algorithms, left ventricular relaxation and filling pressures can be estimated, and the grade of diastolic dysfunction can be classified...

INTRODUCTION: Serum B-type natriuretic peptide (BNP) is frequently elevated after subarachnoid hemorrhage (SAH), but whether this high BNP level is related to transient elevation of left ventricular filling pressure (LVFP) is unknown. However, in patients with preexistent cardiac pathologies, it is impossible to differentiate between BNP elevation caused by chronic cardiac abnormalities and BNP related to acute neurocardiac injury. METHODS: All adult patients with SAH admitted to our intensive care unit were eligible...
