Preliminary results from the Polish Infective Endocarditis Registry (POL-ENDO): time to change clinical approach?

Abstract Background/Aims: Infective endocarditis (IE) is a severe valve disease associated with high morbidity and mortality. The aim of this preliminary study was to evaluate the profile and treatment outcomes of IE in Poland based on the POL-ENDO registry. Methods A prospective cohort, multicenter, observational study - the POL ENDO registry - of IE patients from 134 hospitals in Poland recruited between August 2022 and August 2023 was performed. We evaluated demographic, clinical, imaging, and treatment outcome data. A comparison of the Polish patients with those assessed in the ESC-EORP EURO-ENDO registry was performed. Results Among a total of 880 IE patients, 622 were male (70.7%). The POL-ENDO participants were older (61.4±16.7 years vs. 59.25±18.03 years, p=0.001). Native valve IE (NVIE) occurred more often in Poland (82.3% vs. 56.6%, p <0.001). Transthoracic echocardiography (TTE) was performed more frequently in Poland (93.6% vs. 89.8% p<0.001). New imaging techniques (CT/MRI/PET/SPECT) were less frequently used in Poland (CT: 53.2% vs. 41.3%, p<0.001; MRI: 18.7% vs. 6.4%, p<0.001). Heart failure (HF) occurred more often in Poland as inhospital complication (31.4% vs. 14%, p<0.001). Surgical treatment was less performed in Poland (51.2% vs. 36.9%, p<0.001). Inhospital mortality was higher in Poland (21% vs. 17%, p=0.008). Conclusion Polish patients with IE were significantly older and more comorbid. New imaging techniques are less frequently used in Poland. Echocardiography was performed more frequently in Poland as the diagnostic mainstay. Surgical treatment was significantly less frequent in Poland. Inhospital mortality in Poland is greater. The change of clinical practice in Poland should be considered.
