Background:Despite recent advances in interventional equipment and techniques, the angiographic no-reflow and slow flow phenomenons occurs in a considerable number of patients undergoing primary percutaneous coronary intervention (PCI). We investigated the clinical, electrocardiographic, pre procedural finding that could predict slow flow/ no reflow in ST-segment Elevation Myocardial Infarction (STEMI) patients treated with PCI, also to detect predictors and impact of slow flow/ no reflow during hospital stay and short term outcome of such patients Aim: To identify the clinical, electrocardiographic, pre procedural finding that could predict slow flow/ no reflow in STEMI patients treated with PCI and to determine predictors of adverse clinical events during hospital stay and short term in slow flow /no reflow group. Patients and Methods: Thestudy included 72 patients who were divided into 2 groups, group I with slow flow/no reflow and group II with normal flow. All of them were subjected to follow up for 3months after PCI.

Prediction of fatal arrhythmias in acute myocardial infarction (AMI) is extremely
important. Objective: Create a differential diagnostic model for predicting sudden
cardiac death in elderly patients with STEMI with the history of PCI. Methods: We
studied 152 patients (143 men and 9 women), mean age 70.3±3.4 years, with STEMI
after PCI; EF LV less than 50%. The patients were divided into 2 groups: those who
died on the first day from SCD and those who survived. The QT interval and its parts
were measured upon admission and after PCI. The control group consisted of 30
healthy individuals. Results: A model was developed for determining the level of risk
of arrhythmic death on the first day from SCD after successful PCI based on ECG
criteria using DA. The most informative for the differential diagnosis was a set of the
following indicators: QTd, QTapcd, and SubTd. The most significant indicator is Sub
Td. The following algorithms were developed: ROAD = Qtd x 0.3438 + QTapcd x
0.0842 - SubTd x 0.0864 - 19.5068, NROAD = Qtd x 0.1997 - QTapcd x 0.0148 +
SubTd x 0.3261 - 20.893. Their practical implementation on models is proved.
Conclusion: The creation of a “ROAD/NROAD” differential diagnosis model for
predicting SCD in patients with STEMI after PCI suggests practical application at the
prehospital stage in this category of patients for prophylactically fatal VA and SCD.
Assessment of the possible development of adverse events in patients with STEMI
after PCI is possible using the ECG method based on the use of indicators such as
QTd, QTapcd, and SubTd at the prehospital stage.
