Insights
Complete revascularization (CR) in high-risk ST-segment elevation myocardial infarction (STEMI) patients with Killip class III or higher did not improve outcomes and may increase acute kidney injury risk. Staged CR showed better results than immediate CR.
Area of Science:
- Cardiology
- Interventional Cardiology
- Acute Myocardial Infarction Research
Background:
- Complete revascularization (CR) in ST-segment elevation myocardial infarction (STEMI) patients, particularly those critically ill (Killip class ≥ III), remains controversial.
- Assessing the impact of CR on high-risk STEMI patients with cardiogenic shock is crucial for treatment strategies.
Purpose of the Study:
- To evaluate the effect of complete revascularization (CR) versus culprit-only percutaneous coronary intervention (PCI) on clinical outcomes in STEMI patients with Killip class ≥ III.
- To compare immediate versus staged CR strategies within the same hospitalization.
Main Methods:
- A retrospective study of 185 STEMI patients (Killip class ≥ III) from 2008-2014 who underwent primary PCI.
- Patients were divided into culprit-only PCI (89) and CR groups (96), with CR further divided into immediate (51) and staged (45).
- Thirty-day and 1-year clinical outcomes, including mortality and acute kidney injury, were compared.
Main Results:
- A trend towards lower post-PCI acute kidney injury was observed in the culprit-only PCI group (14.8%) compared to the CR group (26.0%; P=0.069).
- No significant differences in 30-day or 1-year cardiovascular or all-cause mortality were found between culprit-only PCI and CR groups.
- The staged CR group demonstrated decreased 1-year cardiovascular and all-cause mortality compared to the immediate CR group.
Conclusions:
- Complete revascularization in high-risk STEMI patients (Killip class ≥ III) did not improve clinical outcomes and was associated with a higher risk of post-PCI acute kidney injury.
- Staged CR during the same hospitalization was associated with better clinical outcomes than immediate CR.
Background:
The effect of complete revascularization (CR) on high-risk patients with ST-segment elevation myocardial infarction (STEMI) has remains a controversial issue, especially on patients in a critical condition. The aim of this study was to explore the effect of CR on patients with STEMI with Killip class ≥ III.
Methods:
From January 2008 to December 2014, 185 patients diagnosed with STEMI with Killip class ≥ III and multiple vessel coronary artery disease received primary percutaneous coronary intervention (PCI). Eighty-nine patients underwent culprit-only PCI, and the remaining 96 patients underwent immediate or staged PCI for CR. Out of the 96 patients in the CR group, 51 patients underwent immediate CR, and 45 patients underwent CR during the same hospitalization. Thirty-day and 1-year clinical outcomes were compared between the culprit-only PCI group and the CR group as well as between the immediate CR group and staged CR group.
Results:
There was a trend toward a lower incidence of post-PCI acute kidney injury in the culprit-only PCI group when compared with the CR group (14.8% vs. 26.0%; P = 0.069). Thirty-day and 1-year cardiovascular mortality and all-cause mortality were similar between the culprit-only PCI group and CR group. Decreased 1-year cardiovascular mortality and all-cause mortality were noted in the staged CR group compared with the immediate CR group.
Conclusion:
was associated a higher possibility of post-PCI acute kidney injury and did not seem to improve 30-day or 1-year clinical outcomes. Patients undergoing staged CR during the same hospitalization had better clinical outcomes.
