Title

Does the extent of collaterals influence the severity of the myocardial injury as assessed by elevation in biomarkers?

Pages

  49-53

Abstract

 Introduction: Quantitative analysis of cardiac biomarkers, troponin I and CPK-MB, estimates the extent of myocardial injury while extent of benefit from coronary collateral circulation (CCC) to protect myocardium during acute myocardial infarction (AMI) needs validation. We analysed if the extent of collaterals had impact on baseline biomarkers at the time of coronary angiogram. Methods: We analysed 3616 consecutive patients who presented with AMI and underwent invasive coronary angiography (CAG) with intent to revascularisation with biomarkers assessment at the time of CAG. CCC to Infarct related artery (IRA) were graded as per Rentrop grading viz. poorly-developed CCC (Grade 0/1 as Group A) and well-developed CCC (Grade 2/3 as Group B). Results: Both groups (A and B) were matched for demographics, traditional risk factors, SYNTAX 1 Score, time to CAG from onset of angina and eGFR. 36. 59% of patients had Non-ST segment elevation myocardial infarction (NSTEMI) as compared to 63. 41% ST-segment elevation infarction (STEMI). Overall Troponin I (P = 0. 01, P = 0. 01) and CPK MB (P = 0. 00, P = 0. 002) values were lower in group B in both NSTEMI and STEMI groups respectively. Troponin I and CPK-MB were significantly lower in group B [with NSTEMI for SVD (Single vessel disease) (P = 0. 05) and DVD (Double vessel disease) (P = 0. 04), but not for TVD (Triple vessel disease) and with STEMI in SVD (P = 0. 01), DVD (P = 0. 01) and TVD (P = 0. 001)]. Conclusion: Patients with well-developed coronary collaterals had a lower rise in biomarkers in AMI as compared to those with poor collaterals amongst both NSTEMI and STEMI groups.
