Insights
Primary PCI, thrombolytic therapy, and rescue PCI showed similar outcomes for ST-segment elevation myocardial infarction (STEMI) patients. Combining thrombolytic and interventional therapy is safe and effective for STEMI, with rescue PCI potentially improving left ventricular function.
Area of Science:
- Cardiology
- Interventional Cardiology
- Acute Myocardial Infarction Research
Background:
- ST-segment elevation myocardial infarction (STEMI) requires prompt reperfusion therapy.
- Various reperfusion strategies exist, including primary percutaneous coronary intervention (PCI) and thrombolytic therapy.
Purpose of the Study:
- To evaluate the significance of different reperfusion methods in treating acute STEMI.
- To compare the effectiveness and safety of primary PCI, thrombolysis with urokinase, and rescue PCI in STEMI patients.
Main Methods:
- Retrospective analysis of 271 STEMI cases.
- Involved clinical data from ECG, echocardiogram, and angiography.
- Compared outcomes across primary PCI, thrombolysis with urokinase, and rescue PCI groups.
Main Results:
- No significant differences in patient demographics, risk factors, or symptom onset to treatment times were observed between groups.
- Incidence of cardiac events (unstable angina, ventricular arrhythmia, cardiac insufficiency) and key clinical/echocardiographic parameters (Killip class, LVEF) were similar across reperfusion strategies.
- No statistically significant differences were found in collateral circulation or ECG findings (Q waves).
Conclusions:
- Combination therapy of thrombolysis and PCI is a safe and effective treatment for STEMI.
- Rescue PCI may offer benefits for improving left ventricular function in STEMI patients.
- Different reperfusion methods demonstrated comparable short-term clinical and functional outcomes in this STEMI cohort.
Objective:
To evaluate significance of different reperfusion methods in the treatment of acute ST segment elevation myocardial infarction (STEMI).
Methods:
A retrospective analysis of the clinical data of electrocardiography (ECG), echocardiogram, and angiography was conducted in 271 cases of STEMI treated in our hospital. Of these patients 31 were treated by primary percutaneous coronary intervention (PCI), and 44 by intravenous thrombolysis with urokinase, including 26 with thrombolytic treatment with concomitant PCI and 18 with rescue PCI.
Results:
The patients receiving primary PCI, thrombolytic therapy along with PCI, and rescue PCI did not exhibit significant differences in age, sex, diabetes, hypertension, hyperlipidemia, smoking status, symptom onset to treatment time, or collateral circulation (P>0.05). The incidence of cardiac events including unstable angina, complex ventricular arrhythmia, and cardiac insufficiency were not significantly different between the 3 groups (P>0.05), nor was Killip class, number of Q waves on ECG, wall motion score, left ventricular ejection fraction, cardiac index, or stroke volume index (P>0.05).
Conclusion:
Combination of thrombolytic therapy and interventional therapy can be a safe and effective treatment of STEMI, and rescue PCI may benefit the improvement of the left ventricular function.
