Key result
Conduction abnormalities occur in ~29% of acute STEMI cases and are linked to higher in-hospital mortality.
Why the study?
Current-day statistics of conduction abnormalities during the post-reperfusion period in acute STEMI are scarce, particularly in developing countries.
Cross-Sectional (n=100)
No
p-value: p=0.031
Conduction abnormalities remain prevalent in acute STEMI (29%), particularly in inferior-wall infarctions, and are associated with higher in-hospital mortality and a greater need for advanced management like pacing.
Conduction abnormalities may warrant closer monitoring in acute STEMI; this cross-sectional data leaves open independent prognostic value and management effects.
There is clinical importance in identifying abnormalities as a complication of acute ST-elevation myocardial infarction (STEMI), but current-day statistics of conducting abnormalities during the post-reperfusion period are scarce, particularly in developing countries. Objective: The purpose of this research was to examine the occurrence, trend, and prognostic significance of conduction abnormalities in STEMI and their relationship with the site of infarction and in-hospital outcomes. Methods: In this cross-sectional study, 100 patients with acute STEMI were assessed by using a clinical approach, serial electrocardiography, and other pertinent biochemical examinations. To establish associations, chi-square and logistic regression tests were used to conduct a statistical analysis. Results: Abnormalities in conduction were detected in 29% of patients, most often atrioventricular (AV) nodal blocks (74%), the first-degree AV block (27.6) and complete heart block (20.7) were the most common ones. AV nodal blocks (p < 0.05) were significantly associated with inferior-wall infarctions, with anterior-wall infarctions more frequently being complicated by intraventricular conduction delays. The majority of the conduction blocks (93.1) were present on admission and temporary. Permanent pacing was necessary in 5 % of cases, and mortality (4%) was much greater in patients with conduction disturbances (p = 0.031). Conclusion: Conduction abnormalities are also still prevalent in STEMI, particularly in inferior-wall infarctions. Undertaking early detection, rhythm monitoring, and timely reperfusion are all important in minimising the morbidity and mortality of acute coronary care.

Dr Parminder Singh Manghera (2025) conducted a cross-sectional in Acute ST-elevation myocardial infarction (STEMI) (n=100). Conduction block vs. No conduction block was evaluated on In-hospital mortality (p=0.031). Conduction abnormalities were detected in 29% of acute STEMI patients and were significantly associated with increased in-hospital mortality (p=0.031).
