عنوان انگلیسی Exploring the Impact of Fragmented QRS on Ejection Fraction and Other Echocardiographic Parameters in Systemic Sclerosis Patients: A Retrospective Cohort Study
چکیده انگلیسی مقاله Background: Systemic sclerosis (SSc) is an autoimmune connective tissue disorder that leads to fibrosis of the skin and internal organs. Fragmented QRS (fQRS) is an important electrocardiographic (ECG) finding related to myocardial fibrosis. This study aimed to evaluate the effect of fQRS on ejection fraction (EF) and other echocardiographic parameters in individuals diagnosed with SSc. Methods: This was a retrospective cohort study consisting of 52 patients with fQRS as the case group and 60 patients without fQRS as the control group. The characteristics and echocardiographic parameters of the patients from a minimum of a 3-year interval were recorded. All data were compared between the two groups using SPSS software, version 20.0 (IBM Corp). Results: There were no significant differences in demographics, paraclinical results, and echocardiographic parameters, including average EF, pulmonary hypertension, and tricuspid regurgitation velocity, between cases and controls at the beginning and end of the follow-up. Conclusion: Based on our results, fQRS had no significant effect on EF and other echocardiographic parameters over at least a 3-year interval in SSc patients. However, additional research with longer follow-up periods and larger sample sizes is needed to characterize the association fully.
