Evaluating Basic Two-dimensional Echocardiography for Screening in Coronary Artery Disease<\/a><\/p>\n\n\n\n

Background
<\/strong>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<\/strong>
To evaluate basic 2D-echocardiography for CAD screening.
Methods
<\/strong>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 had50% 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<\/strong>
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\u2019s coefficient 0.296); LVEF% was lower (p = 0.002) and negatively correlated (Pearson\u2019s coefficient -0.187). Amongst 154 patients, SYNTAX score correlated negatively with LVEF% (Pearson\u2019s coefficient -0.276) and positively with GAES (Pearson\u2019s 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\u2019s coefficient 0.298) and SYNTAX categories (Spearman\u2019s coefficient 0.110). LVEF% correlated negatively with angiogram results (Spearman\u2019s coefficient -0.307) and SYNTAX categories (Spearman\u2019s coefficient -0.254). <\/p>\n\n\n\n

Conclusions <\/strong><\/p>\n\n\n\n

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.<\/p>\n\n\n\n
