Assessment of left ventricular filling pressure (LVFP) is crucial in patients with ST-segment elevation myocardial infarction (STEMI). Since current guideline recommended echocardiographic parameters have limited value, more comprehensive assessment methods are required in this patient subset.In this study, we aimed to investigate the clinical utility of left atrial reservoir strain (LARS) imaging in patients treated with primary percutaneous coronary intervention (pPCI). Patients who underwent successful pPCI were included. Left ventricular end-diastolic pressure (LVEDP) was measured invasively following pPCI. Left atrial strain imaging was performed following pPCI within 24 h of pPCI. Normal LARS value was accepted as above 23%. We prospectively enrolled 69 patients; there were 18 patients with LARS below 23% who were included into group 1 and rest of the study population included into group 2. There was no significant difference between groups in terms of comorbidities.Troponin and pro-BNP levels were significantly higher in group 1 (p: 0.036 and 0.047 respectively). Left atrial volume and tricuspid regurgitation velocity were similar between groups (p: 0.416 and p: 0.351 respectively). Septal tissue velocity was higher (p: 0.001) and Septal E/e' ratio was lower (p: 0.004) in group 2. Left ventricular (LV) global longitudinal strain value was higher in group 1 which is consistent with observed lower ejection (LVEF) fraction in group 1 (p: 0.001 for LV strain and p: 0.001 for LVEF). Estimated mean LVFP was also higher in group 1 (p: 0.003).Correlation analyses revealed moderate correlation between LARS and LVEDP (r: - 0.300). Our results indicate that left atrial strain imaging is a promising tool for the assessment of left atrial pressure in patients with STEMI.
