“…The investigator must always consider that although in most cases regional wall motion abnormalities are ascribed to underlying ischaemia, this may not be exclusive. Regional wall motion abnormalities may sometimes be encountered in other clinical conditions, such as conduction system (e.g., left bundle branch block), abnormal ventricular interaction (e.g., right sided heart disease, valvular heart disease), and other causes (congenital abnormalities, pregnancy, myocarditis, hypertrophic obstructive cardiomyopathy) [20]. The investigator should always consider and exclude other possibilities.…”

Background: Basic two-dimensional echocardiography (2D-echocardiography) screens for suspected coronary artery disease (CAD) by detecting impaired left ventricular function (LVF) which declines as atherosclerosis worsens. Aim: To evaluate basic 2D-echocardiography for CAD screening.Methods: CAD screening was performed with 2D-echocardiography. For global screening, left ventricular ejection fraction percentage (LVEF%) was determined and categorised into global systolic LVF. For regional screening, global average echocardiography score (GAES) was quantified, then categorised into functional impairment. After screening, high-risk patients underwent diagnostic coronary angiography. Abnormal angiography had >50% luminal stenosis. Angiography was also quantified with Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score, then categorised. Statistical Package for Social Science 25.0 analysed data.Results: There were 471 patients screened for CAD; 154/471 (33%) underwent angiography. For angiography selection amongst 471 screened patients, GAES was higher (p<0.001) and positively correlated (Pearson’s coefficient 0.296); LVEF% was lower (p=0.002) and negatively correlated (Pearson’s coefficient -0.187). Amongst 154 patients, SYNTAX score correlated negatively with LVEF% (Pearson’s coefficient -0.276) and positively with GAES (Pearson’s co-efficient 0.180). For categories, angiography had 66/154 (42.9%) normal and 88/154 (57.1%) abnormal results. SYNTAX score had 134/154 (87.0%) low-risk and 20/154 (13.0%) medium-high-risk categories. GAES correlated positively with angiogram results (Spearman’s coefficient 0.298) and SYNTAX categories (Spearman’s coefficient 0.110). LVEF% correlated negatively with angiogram results (Spearman’s coefficient -0.307) and SYNTAX categories (Spearman’s coefficient -0.254).Conclusions: The distribution of underlying atherosclerotic vessels resulted in regional wall abnormalities being more significant than global function on 2D-echocardiography. We conclude that basic 2D-echocardiography remains useful in CAD screening.

Introduction: Left ventricular (LV) systolic function evaluation is based on ejection fraction assessment. Due to the great sensitivity of the examination and the ease of measurement, systolic time intervals (STIs) are ideally appropriate for studying the effects of pharmacologic agents upon the heart. In this context, the present study aimed to estimate and compare STI in patients with ischemic heart disease (IHD) with clinical heart failure and among control subjects without clinically established LV dysfunction based on their LV ejection fraction (LVEF). Materials and Methods: This case–control study included 33 IHD patients as cases and 32 healthy subjects as controls. All subjects underwent pulsed-Doppler echocardiogram to estimate STIs: total electromechanical systole (QS2), preejection period (PEP), and LV ejection time (LVET). Results: A significant difference between PEP (145.23 ± 23.20 vs. 82.99 ± 8.63, P < 0.00001), LVET (231.34 ± 40.89 vs. 265.39 ± 31.98, P = 0.000947), and PEP/LVET ratio (0.63 ± 0.15 vs. 0.31 ± 0.08, P < 0.00001) between cases and controls was found. On subgroup analysis, a weak correlation was found in patients with LVEF ≤40% and PEP/LVET (r = −0.3677, P = 0.1958). In addition, a relatively strong correlation between LVET and heart rate (r = −0.432, P = 0.012) was found among the cases. Conclusion: The current study results showed that the differences in the values of STI among cases than in controls could be an indicator of LV systolic dysfunction. In addition, this method may have impending applications in the management of IHD.

Non-Ischemic Regional Wall Motion Abnormality

Abstract: Regional wall motion abnormalities (RWMA) are usually described with Ischemic Heart Disease. But many other conditions also show RWMA. What are those conditions, how to recognize RWMA in them and what is it's importance is discussed.
