BACKGROUND: To determine systolic and diastolic function using transthoracic echocardiography in the baboon (Papio hamadryas). METHODS: Transthoracic echocardiography was performed in eight non-pregnant female and six pregnant baboons according to American Society of Echocardiography recommendations. RESULTS: Haemodynamic measurements were obtained from fourteen baboons. Compared to non-pregnant baboons, pregnant baboons demonstrated: (mean ± SD, pregnant vs. healthy) increased cardiac output (1615 ± 121 ml/minutes vs. 1317 ± 134 ml/minutes P = 0.001) due to an increased heart rate [120 ± 11 beats per minute (BPM) vs. 105 ± 6 BPM P = 0.018]. The inter-observer and intra-observer variability ..View full abstract
