ABSTRACT
BACKGROUND: Infective endocarditis (IE) is a severe valvular disease associated with high morbidity and mortality. AIMS: This preliminary study aimed to evaluate patient profiles and treatment outcomes of IE in Poland and compare them with European IE characteristics. METHODS: We conducted a prospective multicenter observational cohort study - the POL-ENDO registry - in IE patients from 134 hospitals in Poland recruited between August 2022 and August 2023. We evaluated demographic, clinical, imaging, and treatment outcome data. A comparison of the Polish patients with those assessed in the EURO-ENDO registry between January 2016 and March 2018 was performed. RESULTS: Of 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 occurred more often in Poland (82.3% vs. 56.6%; P <0.001). Transthoracic echocardiography was performed more frequently in Poland (93.6% vs. 89.8%; P <0.001). New imaging techniques (computed tomography/magnetic resonance imaging/positron emission tomography/single-photon emission computed tomography) were less frequently used in Poland (computed tomography: 41.3% vs. 53.2%; P <0.001; magnetic resonance imaging: 6.4% vs. 18.7%; P <0.001). Heart failure occurred more often in Poland as an in-hospital complication (31.4% vs. 14.1%; P <0.001). Surgical treatment was less frequently performed in Poland (36.9% vs. 51.2%; P <0.001). In-hospital mortality was higher in Poland (21% vs. 17%; P = 0.008). CONCLUSION: Polish IE patients were significantly older and had more comorbidities. 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. In-hospital mortality in Poland is higher.
