Limitations
First, by considering that we excluded the patients with any comorbidity and those taken medications, the main limitation of our study was the small sample size. Second, we selected our cases from outpatient clinic and did not include more severe cases who may need hospitalization and Probably with more severe cardiac involvement including diastolic dysfunction.
