Background: Profound maternal hemodynamic changes occur in order to satisfy the demands of a growing foetus. Early in pregnancy, peripheral vascular resistance (PVR) lowers, generating a considerable rise in cardiac output. Many parameters are employed for measuring the LV systolic function with different echocardiographic modalities including: M-Mode echocardiography, two-dimensional echocardiography, three-dimensional echocardiography, tissue doppler imaging. Objective: To determine the effects of first pregnancy on the LV systolic and diastolic function using Echocardiography. Subjects and Methods: This is a cross sectional study, conducted at Baghdad medical city in the time period from August 2020 to January 2021
