Abstract Background Diastolic dysfunction (DD) is a risk factor for cardiovascular events in patients undergoing non-cardiac surgeries. Investigators aimed to assess the effect of physical activity level on the diastolic function of the left ventricle (LV) in patients attending the preoperative visit. Methods This analytic cross-sectional study was conducted on 228 patients referred to Poursina hospital from November 2021 to March 2022. To define the physical activity level, we used the short form of the International Physical Activity Questionnaire (IPAQ). We categorized patients into inactive, minimally active, and health-enhancing physical activity groups. We also divided participants into three groups based on their daily sitting time. Also, echocardiographic parameters were calculated. The diastolic function of LV was evaluated, and its grading was defined from mild (grade1) to severe (grade 3). Results Results showed that patients with DD had significantly higher age and lower levels of education (P < 0.001 and P = 0.005, respectively). After assessing echocardiographic parameters, we found that E/e’, TR Velocity, left atrial volume index, and pulmonary artery pressure had a statistically significant inverse relationship with physical activity level (P < 0.001 for all). Comparing physical activity level of subgroups showed that in HEPA (health-enhancing physical activity), the chance of developing grade 2 or 3 DD was reduced by 97% compared to the inactive group (OR = 0.03, P < 0.001). Still, there was no significant difference between the inactive and minimally active groups (P = 0.223). Conclusions This study showed an inverse relationship between physical activity level and DD of the LV in a sample of 228 individuals attending the Anesthesia Clinic, independent of potentially confounding variables.Therefore, due to lower rate of DD in patients who are physically active, we can expect lower occurrence rate of cardiovascular events during surgery.
