Objective:

this is a letter to editor We have read with great interest the paper entitled 'Subclinical Atherosclerosis in Patients with Prior Pulmonary Thromboembolism' Buyukterzi et al.1 is very important study. We have some suggestions about this trial. Firstly there are several echocardiographic parameters are available to determine right ventricular functions. Fractional area change (FAC), tricuspit annular plane systolic excursion (TAPSE), tissue Doppler derived right ventricular systolic excursion velocity S', strain and strain rate are the major determiner of right ventricular systolic functions. Moreover we can evaluate global right ventricular functions with myocardial performance indexes.2 Because of higher intraobserver variability right ventricular size measurement is not the gold standard the assesment of right ventricular functions. We can also determine it with radionuclid anjiography or cardiac magnetic resonance imaging.3 Secondly if right ventricular functions diminishes, left ventricular functions may influence. Left ventricular functions are not detected comprehensive by their. For example tissue Doppler parameters and diastolic dysfunction parameters.4 We wonder the patients characteristics that how many patients had major pulmoary thromboembolism and received thrombolitic treatment. In this study there wasn't detected any inflammatory markers and elevated pressure or volume overload were not detected with brain natriuretic peptide levels or N-terminal brain natriuretic peptide levels.5
