Context: No-flow phenomenon during percutaneous coronary intervention (PCI) is a complex and multifactorial phenomenon with often devastating complications during PCI, especially in acute coronary syndrome (ACS) settings. There is paucity of data on serological predictors of the same. Materials and Methods: This was an open-label, all-comers, observational, prospective study done on 175 patients covering the whole spectrum of coronary artery disease, undergoing PCI at the center. On admission detailed clinical history , general and systemic examination and laboratory investigations in form of hemoglobin, blood urea, serum creatinine, serum sodium, serum potassium, random blood sugar, electrocardiogram(ECG) and tropinin T were also done. Post procedure creatinine protein kinase MB (CPK MB) was done after 24 hrs, and thrombolysis in myocardial infarction (TIMI) flow was assessed during PCI in all patients by the operating interventional cardiologist. Results: The mean value of NT-proBNP among patients with TIMI flow <3 was 3384.43 ± 1837.48 pg/ml, whereas among patients with TIMI flow 3, it was 894.64 ± 580.90 pg/ml. The difference between the two groups was statistically significant (P < 0.001), with TIMI flow 3 Group showing significantly lower mean NT-proBNP values as compared to the TIMI flow <3 category. There was no significant correlation between the mean NT-proBNP levels in various TIMI flow, that is, 0 and 2. In each quartile of NT-proBNP, there was a marked difference in the quartile value of the two TIMI <3 and TIMI 3 categories. Presence of angiographic thrombus was significantly associated with no-flow phenomenon. Conclusion: Our study shows that higher NT-proBNP levels in patients with ACS who undergo PCI have higher likelihood of developing no-flow phenomenon during PCI.
