Insights
This study found no significant difference in long-term survival for patients with anterior-wall versus non-anterior-wall ST-segment elevation myocardial infarction (STEMI). However, anterior STEMI was linked to higher short-term mortality and worse heart function.
Area of Science:
- Cardiology
- Clinical Research
- Public Health
Background:
- ST-segment elevation myocardial infarction (STEMI) localizations vary in severity and impact.
- Differences in myocardial damage, culprit vessel, and right ventricular involvement exist between anterior and non-anterior STEMI.
- Understanding long-term survival differences is crucial for patient management.
Purpose of the Study:
- To investigate if anterior-wall STEMI (AWS) has a different long-term survival rate compared to non-anterior-wall STEMI (NAWS).
- To analyze the association between STEMI localization and long-term all-cause mortality.
Main Methods:
- Utilized data from 2,195 STEMI cases recorded by the Augsburg Myocardial Infarction Registry (2009-2017).
- Included 1,570 men and 625 women aged 25-84 years at the time of infarction.
- Performed survival and multivariable Cox regression analyses with an average follow-up of 4.3 years.
Main Results:
- No significant association was found between STEMI localization and long-term mortality (HR 0.91 [0.75-1.10] for AWS vs. NAWS).
- Anterior STEMI (AWS) showed higher short-term (<28 day) mortality compared to NAWS.
- AWS patients had lower smoking rates, higher CK-MB levels, and more frequent impaired left ventricular ejection fraction (<30%).
Conclusions:
- Despite differing clinical characteristics and pathophysiological aspects, anterior and non-anterior STEMI do not exhibit significant differences in long-term survival.
- Anterior STEMI is associated with worse short-term outcomes and indicators of more severe cardiac damage.
Background:
Different ST-segment elevation myocardial infarction (STEMI) localizations go along with dissimilarities in the size of the affected myocardium, the causing coronary vessel occlusion, and the right ventricular participation. Therefore, this study aims to clarify if there is any difference in long-term survival between anterior- and non-anterior-wall STEMI.
Methods:
This study included 2,195 incident STEMI cases that occurred between 2009 and 2017, recorded by the population-based Augsburg Myocardial Infarction Registry, Germany. The study population comprised 1.570 men and 625 women aged 25-84 years at acute myocardial infarction. The patients were observed from the day of their first acute event with an average follow-up period of 4.3 years, (standard deviation: 3.0). Survival analyses and multivariable Cox regression analyses were performed to examine the association between infarction localizations and long-term all-cause mortality.
Results:
Of the 2,195 patients, 1,118 had an anterior (AWS)- and 1,077 a non-anterior-wall-STEMI (NAWS). No significant associations of the STEMI localization with long-term mortality were found. When comparing AWS with NAWS, a hazard ratio of 0.91 [95% confidence interval: 0.75-1.10] could be calculated after multivariable adjustment. In contrast to NAWS, AWS was associated with a greater <28 day mortality, less current or former smoking and higher creatine kinase-myocardial band levels (CK-MB) and went along with a higher frequency of impaired left ventricular ejection fraction (<30%).
Conclusions:
Despite pathophysiological differences between AWS and NAWS, and identified differences in multiple clinical characteristics, no significant differences in long-term mortality between both groups were observed.
