Συσχέτιση των υπερηχογραφικών δεικτών της δεξιάς κοιλίας (rvd1, s'-tdi, tapse) με τη μεταβολή της κάτω κοίλης φλέβας σε ασθενείς με πνευμονική υπέρταση

Correlation of the echocardiographic parameters of the right ventricle (rvd1, s'-tdi, tapse) with the variation of inferior vena cava in patients with pulmonary hypertension

Introduction: Pulmonary Hypertension as a nosological entity, includes various pathophysiological mechanisms with a common denominator the remodeling of the pulmonary endothelium. Patients often develop symptoms similar to those of heart failure, which results in frequent hospital admissions for further treatment.
Aim of this study was to establish the correlation between the echocardiographic parameters of the right ventricle in comparison with the changes of the vena cava diameter in patients with Pulmonary Hypertension.
Material and Method: The sample consisted of 103 patients with Pulmonary Hypertension who were hospitalized at the General Hospital ‘G. Gennimatas’ during the years 2018-2019 and underwent transthoracic ultrasound. Data of the present study were extracted from the above mentioned ultrasounds. The statistical analysis was performed using the R programming language and more specifically the ‘R Studio’ software. The level of significance 0.05 , was considered statistically important, while the Pearson Correlation Coefficient (R) was used.
Results: The systolic wave S’ is demonstrated as a sensitive index of early impairment of right ventricular function at the studied population of 103 patients, divided into three classes according to the severity of the disease (35-45, 46-59, 60-85 mmHg), p-value < 0,05 for the second category of the population.However, as the severity of the disease increases, there is a more immediate response and a further increase in the basal diameter (RVD1) as an adaptation mechanism to the right ventricular pressure overload. (p-value > 0,05 for all categories). The other echocardiographic indicators follow along, considering the values they receive (p-value >0,05).

Conclusion: The present study clearly demonstrates the correlation between increasing disease severity and decreasing right ventricular function as shown by s’-TDI, TAPSE and RVD1 values
