| Popis: | Introduction: Recent developments in echocardiography made assessing pulmonary arterial hypertension (PAH) in the heart, a suitable choice. This study aimed to investigate the association of myocardial right ventricular relaxation time and systolic pulmonary artery pressure (SPAP) in PAH patients.Materials and Methods: The present study evaluated 74 patients with PAH (n=49) and age- and sex-matched healthy controls (n=25). All patients underwent transthoracic echocardiography. We evaluated the right ventricular (RV) function's echocardiographic parameters, including IVRT, IVCT, S, E, A, S’, E’, A’, ET, DT, TAPSE, FAC, and SPAP.Results: We found no significant differences in age and gender between the two studied groups (p>0.05). However, we observed a significant difference in IVRT, IVCT, E’, A’ (p=0.004), A, S’, DT, TAPSE, FAC and SPSP (p0.05).Conclusion: Our findings revealed that IVRT and IVCT might not be affected by the SPAP and, therefore, could be used in the assessment of right ventricular function in patients with PAH. |
