“…However, all these changes are much earlier than the ECG hints. 36 Our study confirms these studies and we found that although multiple echocardiographic parameters have shown reduced LV diastolic function in TVD patients, a significantly lower proportion of ST-T abnormalities occurred in group B than in group C. One probable explanation is that although TVD patients with widespread lesions, most patients with artery stenosis rate of 50% to 75% keep a balance between the blood supply-demand of the ischemic area and the normal cardiac tissue. So the symptoms of angina are often temporary and without persistent ST-T abnormalities.…”

“…Animal tests and clinical studies have shown that myocardial ischemia first presents with alterations at biochemical level, and then diastolic dysfunction develops earlier than segmental ventricular wall motion abnormalities. However, all these changes are much earlier than the ECG hints 36 .

Objective To evaluate left atrial function in patients with triple‐vessel disease (TVD) without myocardial infarction by real‐time three‐dimensional echocardiography (RT‐3DE) and two‐dimensional speckle tracking imaging (2D‐STE). Methods Sixty patients with coronary artery disease (CAD) without myocardial infarction were classified into two groups in accordance with the coronary angiography results: group B (all triple‐vessel stenosis ≥ 50% and < 75%) and group C (all triple‐vessel stenosis ≥ 75%). Thirty healthy individuals were selected as group A. LA volume related parameters including left atrial maximum volume index (LAVImax), LA passive and active ejection fraction (LAPEF, LAAEF) and LA total ejection fraction (LATEF) were measured by RT‐3DE. The global peak atrial longitudinal systolic strain (LASRs), early and late diastolic LA strain (LASRe and LASRa) rates were measured by 2D‐STE. Results We found statistically significant differences between 2D‐STE and RT‐3DE related parameters of these three groups. Furthermore, in groups B and C, N‐terminal fragment brain natriuretic peptides (NT‐pro‐BNP) and left ventricular end‐diastolic pressure (LVEDP) were found to be significantly correlated with LASRs and LASRa. And NT‐pro‐BNP had a moderate correlation with LVEDP. Conclusions 2D‐STE and RT‐3DE can assess the LA function in patients with TVD without myocardial infarction. And LA strain values may provide additional information for predicting increased LVEDP and NT‐pro‐BNP.

“…According to the literature, when myocardial ischemia occurs, it is first the biochemical levels that are altered, followed by dysfunction. [ 45 ] There was a better negative correlation between NT-proBNP and RASRs and a better positive correlation with RASRe and RASRa in groups B and C, indicating that NT-proBNP and 2D-STE were consistent in evaluating right atrial function. Similarly, the results of the Gensini score in lesion groups showed a more significant negative correlation with RASRs, and a more significant positive correlation with RASRe and RASRa, indicating that 2D-STE can better assess the function of the right atrium in patients without myocardial infarction with TBCAD.…”

To evaluate the right atrial function in patients with 3-branch coronary artery disease (TBCAD) without myocardial infarction by 2D speckle tracking echocardiography (2D-STE) combined with real-time 3-dimensional echocardiography (RT-3DE). Fifty-six patients admitted to our hospital without myocardial infarction with TBCAD were selected. We divided them into 2 groups according to the coronary angiography results: 28 patients in group B (the rate of stenosis is 50% ~< 75%); 28 patients in group C (the rate of stenosis is ≥75%); in addition, 30 healthy volunteers were screened as group A. All subjects underwent RT-3DE to obtain the right atrial volume (RAVmax, RAVmin, and RAVp), and then we calculated the right atrial passive and active ejection fraction (RAPEF, RAAEF), and maximum volume index (RAVImax). In addition, to measure the strain rates (RASRs, RASRe, RASRa) of the right atrium during systole, early diastole, and late diastole, 2D-STE was applied. Correlations between the 2D-STE parameters and the results of N-terminal pro-brain natriuretic peptide (NT-proBNP) and Gensini scores were analyzed by Pearson linear analysis. Compared with group A, RAPEF and RASRe were reduced, while RAAEF and RASRa were elevated in group B (P < .05). RAPEF, RASRs, RASRe, and RASRa were decreased compared with groups A and B, while RAVmax, RAVmin, RAVp, RAVImax, and RAAEF were increased in group C (P < .05). There was a significant correlation between 2D-STE parameters and the results of NT-proBNP and Gensini scores (P < .05). The storage, conduit, and pump functions of the right atrium are reduced in patients with 3-branch coronary artery disease without myocardial infarction; 2D-STE combined with RT-3DE is valuable in the evaluation of the right atrium in patients with coronary artery disease.

“…Alarm warning is triggered when ECG frequency greater than the programmed value is detected, when ectopic activity is detected and when there is increment or decrement of ST segment. ST segment is the part of the ECG from the end of the QRS complex to the beginning of the T wave (Azoz et al 2018).…”
