Abstract :
: Almost half of the causes of cardiovascular
death are the result of Acute Myocardial Infarction
(AMI). Acute coronary syndrome (ACS) consisting of
unstable angina pectoris (APTS), non-ST elevation acute
myocardial infarction (IMANEST) and ST elevation
acute myocardial infarction (AMIEST) was the leading
cause of death in adults and accounted for 16.7% of
deaths from all groups. age. The SYNTAX score is a score
system that is comprehensively formulated to describe the
complexity of coronary artery lesions based on
angiographic results and predict the final outcome of
percutaneous coronary intervention (IKAP) or coronary
artery bypass grafting.(CABG). QRS (fQRS)
fragmentation on the ECG is associated with the presence
of myocardial scarring, ischemia, and fibrosis stemming
from defects in signal transduction processes and
ventricular depolarization.
Objective: The purpose of this study was to determine the
relationship between QRS fragmentation and the severity
of coronary artery lesions as assessed by the SYNTAX
score in patients with acute coronary syndromes.
Methods: The study involved acute coronary syndrome
patients who underwent coronary angiography at the
Haji Adam Malik General Hospital in Medan in the
period January 2020 to October 2020. All subjects
underwent ECG examination and SYNTAX score
assessment. Statistical analysis was performed to assess
QRS fragmentation with the severity of coronary artery
lesions.
Results: 27 subjects with QRS fragmentation experienced
moderate-severe lesion severity as many as 25 people
(46.3%) and only 2 people with low lesion severity (3.7%),
while 22 subjects without QRS fragmentation had lesion
severity. low coronary arteries and only 5 people (9.3%)
had moderate-severe lesions. Based on the analysis, there
was a statistically significant relationship between QRS
fragmentation images and the severity of coronary artery
lesions in patients with acute coronary syndromes with p
value < 0.001. Patients with QRS fragmentation
compared with non-fragmented QRS patients had a 35x
risk of experiencing moderate-severe severity. A total of
27 subjects found that QRS fragmentation had a
moderate strength relationship with the SYNTAX score
and the direction of the correlation was positive and
statistically significant.
Conclusion: There is a relationship between QRS
fragmentation in patients with acute coronary syndromes
and the severity of coronary artery lesions as assessed by
the SYNTAX score.
Keywords :
