“…All invasive and noninvasive techniques evaluating RV performance have important limitations due to the complex geometry of the right ventricle [3][4][5][6][7][8][9][10][11][12][13][14][15]. The introduction of Doppler measurement of myocardial wall velocities (tissue Doppler imaging; TDI) and the recently developed strain rate imaging (SRI) technique have made a more adequate assessment of global and regional systolic and diastolic RV function possible [16][17][18][19][20][21][22][23].…”

The purpose of the current study was to compare right ventricular (RV) myocardial wall velocities (tissue Doppler imaging) and strain rate imaging (SRI) parameters with conventional echocardiographic indices evaluating RV function in chronic obstructive pulmonary disease (COPD) patients.In total, 39 patients with COPD and 22 healthy subjects were included in the current study. Seventeen patients had pulmonary artery pressure ,35 mmHg (group I) and 22 patients had pulmonary artery pressure .35 mmHg (group II). Tissue Doppler imaging, strain and strain rate (SR) values were obtained from RV free wall (FW) and interventricular septum. Respiratory function tests were performed (forced expiratory volume in one second/vital capacity (FEV1/VC) and carbon monoxide diffusion lung capacity per unit of alveolar volume (DL,CO/VA)).Strain/SR values were reduced in all segments of group II patients compared with group I patients and controls with lowest values at basal FW site. A significant relationship was shown between peak systolic SR at basal FW site and radionuclide RV ejection fraction. A significant relationship was shown between peak systolic SR at basal FW site and DL,CO/VA and FEV1/VC.In conclusion, in chronic obstructive pulmonary disease patients, strain rate imaging parameters can determine right ventricular dysfunction that is complementary to conventional echocardiographic indices and is correlated with pulmonary hypertension and respiratory function tests.

“…However, it is well established that PASP does not become elevated until the terminal stage in patients with chronic emphysema (12) and inveterate pulmonary tuberculosis (13). The present study did not include severe stages of lung disease directly contributing to such an elevation, such as, cor pulmonale.…”

Pulmonary Artery Systolic Pressure is Elevated in the Elderly: Relationships between Echocardiographic and Pathological Findings

Objective We investigated the relationship between the right cardiac system and increased pulmonary artery systolic pressure (PASP) in the elderly.Patients and Methods Echocardiography stable state data were available for 163 of 200 consecutive autopsied patients. Of these, PASP could be estimated by extrapolation from the maximum pressure gradient in tricuspid valve regurgitation from echocardiograms in 73 cases; however, 22 cases with secondary changes attributable to left cardiac insufficiency had to be excluded. We studied the remaining 51 patients in detail (16 men, 35 women, age 68-103 years; mean, 87.7±8.1). We investigated the following: echocardiographic and pathologic variables, age, sex, body mass index, the survival time (from echocardiography to autopsy), and the presence or absence of chronic pulmonary disease.Results

“…The RV Tei index is clinically useful and reliable to assess the RV impairment before the development of RV insufficiency (25,26) and it is not influenced by changes in HR, right ventricular pressure, right ventricular dilation, or tricuspid regurgitation (7). In contrast to the LV function exposed to high altitudes, little is known about the RV function under hypoxic stress.…”

Myocardial Performance Index in Subjects Susceptible to High-Altitude Pulmonary Edema

et al. 2011

Objective A recent study concerning high-altitude pulmonary edema (HAPE), a non-cardiogenic pulmonary edema, suggested that it is initially a hydrostatic-type pulmonary edema. We suspect that some extent of cardiac insufficiency may likely relate to the mechanism of the development of this disease. Methods By Doppler echocardiography, the Tei index (a new quantitative index proposed for the evaluation of global myocardial performance) and the systolic pulmonary artery pressure (sPAP) were measured before and after 30 minutes of hypoxic breathing. Patients Eleven HAPE-susceptible subjects (HAPE-s) and nine HAPE-resistant subjects (HAPE-r).Results The results of Tei index indicated an enhanced left myocardial performance but an impaired right performance in HAPE-s during hypoxic breathing. The sPAP of HAPE-s was significantly increased after hypoxic breathing, which was not correlated with the heart functions such as right ventricular (RV) Tei index, cardiac index (CI), percent ejection fraction (EF%) and percent fractional shortening (FS%) under hypoxic condition. Comparatively, the HAPE-r subjects did not show such significant changes of Tei index after hypoxic breathing. The results suggested that a paradoxical myocardial performance, in a format of an augmented left ventricular (LV) in contrast to an attenuated RV, was observed in the HAPE-s exposed to acute hypoxia. Conclusion The responses of the left and right myocardial performances to hypoxia may be involved in the pathogenesis of HAPE.
