Why the study?
The no-reflow phenomenon affects approximately one in five PPCI patients and is linked to unfavorable outcomes, making early recognition critical.
Do baseline ECG findings predict the occurrence of the no-reflow phenomenon in patients undergoing primary percutaneous coronary intervention?
Do baseline ECG findings predict the occurrence of the no-reflow phenomenon in patients undergoing primary percutaneous coronary intervention?
Baseline ECG parameters such as prolonged QRSD, delayed RWPT, fQRS, and Q waves can help predict the risk of no-reflow phenomenon in patients undergoing primary PCI.
Background: The no-reflow phenomenon affects about one out of five patients undergoing Primary Percutaneous Coronary Intervention (PPCI). As the prolonged no-reflow phenomenon is linked with unfavorable outcomes, making early recognition is crucial for effective management and improved clinical outcomes in these patients. Our review study aimed to determine whether electrocardiogram (ECG) findings before PCI could serve as predictors for the occurrence of the no-reflow phenomenon. Methods and materials: We systematically searched MEDLINE, Scopus, and Embase to identify relevant studies. The random-effect model using inverse variance and Mantel-Haenszel methods were used to pool the standardized mean differences (SMD) and odds ratios (OR), respectively. Result: wave maximum duration (Pmax) on baseline ECG. Conclusion: Our findings suggest that prolonged QRSD, delayed RWPT, higher fQRS prevalence, and the presence of a Q wave on baseline ECG may predict the occurrence of the no-reflow phenomenon in patients undergoing PPCI.
