Correlation of Standard ECG with 2D-Echo and Serum Troponin I in Locating the Site of Myocardial Infarction and its Extent- An Observational Study
Introduction: Cardiovascular diseases are the leading causes of death in developed countries, and its incidence is on the rise in developing countries.

| 520 | |a Introduction: Cardiovascular diseases are the leading causes of death in developed countries, and its incidence is on the rise in developing countries. Electrocardiogram (ECG), 2 Dimensional Echocardiography (2D-Echo) and myocardial injury biomarkers help in the diagnosis, prognostification of Myocardial Infarction (MI). Aim: To correlate the findings of ECG, 2D-Echo and Troponin I levels in locating the site and extent of MI. Materials and Methods: This observational study was conducted in the Cardiology Intensive Care Unit (ICU)/ward, PES Hospital, Kuppam, Andhra Pradesh, India, from January 2019 to June 2020. A total of 99 patients of acute MI were studied at baseline, and repeat 12 lead ECG, 2D-Echo and serum troponin I levels were recorded. Ejection Fraction (EF) was estimated from the QRS score by means of a formula, and Echocardiographic correlation was obtained on the same day with ECG-QRS scoring by direct estimation of EF in ‘Q’ wave infarction. High sensitivity cardiac Troponin – I was measured at the time of hospitalisation and repeated at six hours if required, and its levels were correlated to the extent of MI i.e., Left Ventricular Ejection Fraction (LVEF). The categorical data were analysed using Chi-square test and p<0.05 was considered as statistically significant. Regression analysis was done for associated factors. Results: There was better correlation between EF calculated from ECG-QRS scoring system and 2D-Echo (r=0.78, p-value <0.001). There was poor correlation between serum Troponin I levels at admission, and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-237.13, p=0.334 and r=-120.78, p=0.585). There was a significant correlation between serum Troponin I levels at 72 hours of chest pain or peak values and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-1446.14, p<0.001 and r=-1354.42, p<0.001). Conclusion: The location of MI, seen on ECG, correlated broadly with those seen on 2D-Echo. 2D-Echo was able to elaborate regional wall motion abnormalities in detail when compared to the ECG. LVEF can be calculated from ECG at bedside in Q wave infarction, which correlated fairly with 2D-Echo findings. | ||

Electrocardiogram (ECG), 2 Dimensional Echocardiography (2D-Echo) and myocardial injury biomarkers help in the diagnosis, prognostification of Myocardial Infarction (MI). Aim: To correlate the findings of ECG, 2D-Echo and Troponin I levels in locating the site and extent of MI. Materials and Methods: This observational study was conducted in the Cardiology Intensive Care Unit (ICU)/ward, PES Hospital, Kuppam, Andhra Pradesh, India, from January 2019 to June 2020. A total of 99 patients of acute MI were studied at baseline, and repeat 12 lead ECG, 2D-Echo and serum troponin I levels were recorded. Ejection Fraction (EF) was estimated from the QRS score by means of a formula, and Echocardiographic correlation was obtained on the same day with ECG-QRS scoring by direct estimation of EF in ‘Q’ wave infarction. High sensitivity cardiac Troponin – I was measured at the time of hospitalisation and repeated at six hours if required, and its levels were correlated to the extent of MI i.e., Left Ventricular Ejection Fraction (LVEF). The categorical data were analysed using Chi-square test and p<0.05 was considered as statistically significant. Regression analysis was done for associated factors. Results: There was better correlation between EF calculated from ECG-QRS scoring system and 2D-Echo (r=0.78, p-value <0.001). There was poor correlation between serum Troponin I levels at admission, and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-237.13, p=0.334 and r=-120.78, p=0.585). There was a significant correlation between serum Troponin I levels at 72 hours of chest pain or peak values and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-1446.14, p<0.001 and r=-1354.42, p<0.001). Conclusion: The location of MI, seen on ECG, correlated broadly with those seen on 2D-Echo. 2D-Echo was able to elaborate regional wall motion abnormalities in detail when compared to the ECG. LVEF can be calculated from ECG at bedside in Q wave infarction, which correlated fairly with 2D-Echo findings. electrocardiogram qrs scoring system left ventricular ejection fraction q wave infarction regional wall motion abnormalities Medicine R TR Pandiyan verfasserin aut Srinivasa Rao verfasserin aut YJ Visweswara Reddy verfasserin aut PE Dhananjaya verfasserin aut In Journal of Clinical and Diagnostic Research JCDR Research and Publications Private Limited, 2009 16(2022), 3, Seite OC05-OC09 (DE-627)789478048 (DE-600)2775283-5 0973709X nnns volume:16 year:2022 number:3 pages:OC05-OC09 https://doi.org/10.7860/JCDR/2022/53075.16071 kostenfrei https://doaj.org/article/c7058d79f5d549198b5d6b37c39d0ee8 kostenfrei https://www.jcdr.net/articles/PDF/16071/53075_CE[Ra1]_F(KR)_PF1(AG_SS)_PFA(AG_KM)_PN(KM).pdf kostenfrei https://doaj.org/toc/2249-782X Journal toc kostenfrei https://doaj.org/toc/0973-709X Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_73 GBV_ILN_74 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_602 GBV_ILN_2005 GBV_ILN_2009 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2055 GBV_ILN_2111 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 16 2022 3 OC05-OC09 |

Correlation of Standard ECG with 2D-Echo and Serum Troponin I in Locating the Site of Myocardial Infarction and its Extent- An Observational Study |
| abstract |
Introduction: Cardiovascular diseases are the leading causes of death in developed countries, and its incidence is on the rise in developing countries. Electrocardiogram (ECG), 2 Dimensional Echocardiography (2D-Echo) and myocardial injury biomarkers help in the diagnosis, prognostification of Myocardial Infarction (MI). Aim: To correlate the findings of ECG, 2D-Echo and Troponin I levels in locating the site and extent of MI. Materials and Methods: This observational study was conducted in the Cardiology Intensive Care Unit (ICU)/ward, PES Hospital, Kuppam, Andhra Pradesh, India, from January 2019 to June 2020. A total of 99 patients of acute MI were studied at baseline, and repeat 12 lead ECG, 2D-Echo and serum troponin I levels were recorded. Ejection Fraction (EF) was estimated from the QRS score by means of a formula, and Echocardiographic correlation was obtained on the same day with ECG-QRS scoring by direct estimation of EF in ‘Q’ wave infarction. High sensitivity cardiac Troponin – I was measured at the time of hospitalisation and repeated at six hours if required, and its levels were correlated to the extent of MI i.e., Left Ventricular Ejection Fraction (LVEF). The categorical data were analysed using Chi-square test and p<0.05 was considered as statistically significant. Regression analysis was done for associated factors. Results: There was better correlation between EF calculated from ECG-QRS scoring system and 2D-Echo (r=0.78, p-value <0.001). There was poor correlation between serum Troponin I levels at admission, and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-237.13, p=0.334 and r=-120.78, p=0.585). There was a significant correlation between serum Troponin I levels at 72 hours of chest pain or peak values and extent of MI i.e., LVEF as estimated by ECG and 2D-Echo (r=-1446.14, p<0.001 and r=-1354.42, p<0.001). Conclusion: The location of MI, seen on ECG, correlated broadly with those seen on 2D-Echo. 2D-Echo was able to elaborate regional wall motion abnormalities in detail when compared to the ECG. LVEF can be calculated from ECG at bedside in Q wave infarction, which correlated fairly with 2D-Echo findings. |
