Opis:
Introduction and objective. Single ventricle anomaly is one of the complex congenital heart defects. A dependable non-invasive method of evaluation of Fontan circulation haemodynamics for early diagnosing unstable patients is hardly available in routine clinical practice. The aim of the study is non-invasive evaluation of the haemodynamic parameters in patients after Fontan operation. Materials and method. The study involved 11 participants (age 24.4±4.3 years) with functionally univentricular hearts after Fontan operation. Evaluation of haemodynamic parameters was performed in supine and sitting positions using the impedance cardiography method. Results. In comparative analysis, heart rate (70.1 vs.78.3 1/min; p=0.001), diastolic blood pressure (73.9 vs. 76.7 mm Hg; p=0.026), mean arterial blood pressure (84.5 vs. 88.0 mm Hg; p=0.013), systemic vascular resistance (1284.8 vs. 1334.9 dyn*s*cm-5; p=0.024), systemic vascular resistance index (2178.7 vs. 2272.8 dyn*s*cm-5*m2; p=0.018), pre-ejection period (124.2 vs. 136.2 ms; p=0.009), systolic time ratio (0.43 vs. 0.53; p=0.0001), and Zo (26.2 vs. 28.7 Ω; p<0.00001), were significantly higher in the sitting position. Stroke volume (75.4 vs. 68.5 ml; p=0.013), stroke index (42.7 vs. 39.0 ml*m-2; p=0.014), thoracic fluid content (38.5 vs. 35.4 1*kΩ-1; p=<0.00001), thoracic fluid content index (22.8 vs. 21.0 1*kΩ-1*m-2; p=<0.00001), and left-ventricular ejection time 291.1 vs. 260.1 ms; p=<0.00001, were significantly higher in the supine position. Conclusions. In patients after Fontan procedure, impedance cardiography can be a useful tool the assessment of shortterm haemodynamic changes provoked by postural changes. Its clinical value in patients with congenital heart defects should be further investigated.

Opis:
Introduction and objective. Physical effort plays a positive role in reducing the risk of cardiovascular diseases. The aim of this study was to assess the cardiovascular status in postmenopausal women after several years of regular amateur training. Materials and method. A total of 55 generally healthy females aged 50–70 years, of whom 38 were members of a senior exercise group and 17 comprised a control group, were enrolled in the study. Parameters of blood flow, vascular resistance, myocardial contractility and thoracic fluid content were measured in a 10-minute supine resting test by impedance cardiography. Thereafter, central blood pressure, augmentation index and pulse wave velocity were measured by applanation tonometry. Results. Exercising women have a better outcome than the control group, when evaluated both with impedance cardiography and with applanation tonometry. They have a lower heart rate – HR (65.1 vs 71.5; p=0.033), higher blood flow (stroke index – SI, 58.6 vs 50.3; p=0.040), better myocardial contractility (acceleration index – ACI, 108.8 vs 88.1; p=0.027), higher preload (thoracic fluid content index – TFCI, 20.5 vs 18.1; p=0.002), lower afterload (systemic vascular resistance index – SVRI, 1972.9 vs 2110.5; p=0.026), lower central systolic blood pressure – cBPsys (119.0 vs 129.5; p=0.037), lower augmentation pressure – AP (10.3 vs 15.0; p=0.044) and lower pulse wave velocity – PWV (7.4 vs 8.4; p=0.001). Conclusions. Regular moderate continuous aerobic exercise training has a beneficial impact on the cardiovascular system in postmenopausal women.
