ECHOCARDIOGRAPHIC CHANGES IN PREGNANT PATIENTS ATTENDING RURAL TERTIARY CARE HOSPITAL-DBVPRMC, LONI.

During pregnancy, signicant physiological adaptations support increased metabolic demands and fetal development, particularly affecting the cardiovascular, respiratory, hematological, and renal systems. Echocardiographic ndings in pregnant women at a rural tertiary care hospital showed increased stroke volume (63.71 ± 5.16 mLvs. 55.0 ± 4.9 mL), cardiac output (5406.39 ± 684.78 mL/min vs. 4500 ± 600 mL/min), and left ventricular mass (168.11 ± 3.39 g vs. 140.0 ± 10.0 g), indicating cardiac remodeling. Pregnancy increases demand on the cardiovascular system, leading to signicant adaptations, including higher cardiac output (CO), plasma volume, stroke volume (SV), and heart rate (HR), along with decreased systemic vascular resistance (SVR) and mean arterial pressure. Hemodynamic changes included elevated heart rate (84.79 ± 7.62 bpm vs. 75.00 ± 6.50 bpm) and systolic BP (120.84 ± 7.05 mmHg vs. 115.00 ± 6.80 mmHg), with lower diastolic BP and MAP. Doppler ndings revealed reduced isovolumetric relaxation time and increased ejection time. These adaptations optimize maternal-fetal circulation but require careful anesthetic management, considering increased oxygen consumption, hypercoagulability, and altered drug sensitivity. Understanding these changes enhances obstetric and perioperative care.
