Association between SYNTAX Score and Coronary Collateral Circulation
DOI: 10.5935/abc.20170156
Dear Editor,
I have read the article entitled “Which Coronary Lesions Are More Prone to Cause Acute Myocardial Infarction?” by Sen et al. with great interest, recently published in journal. The investigators reported that more than 70% of the patients with acute myocardial infarction (MI) had coronary collateral circulation (CCC) with Rentrop scores of 1-3 during primary coronary angiography. This shows that most cases of acute MI in our study originated from underlying high-grade stenosis, challenging the common believe. Higher serum triglycerides levels, greater mean platelet volume, and increased white blood cell and neutrophil counts were independently associated with impaired development of collateral vessels.
