RESUMO
BACKGROUND: Despite its benefits, oral anticoagulant (OAC) therapy in patients with atrial fibrillation (AF) is associated with hemorrhagic complications. AIMS: We aimed to evaluate clinical characteristics of AF patients at high risk of bleeding and the frequency of OAC use as well as identify factors that predict nonuse of OACs in these patients. METHODS: Consecutive AF patients hospitalized for urgent or planned reasons in cardiac centers were prospectively included in the registry in 2019. Patients with HAS-BLED ≥3 (high HAS-BLED group) were assumed to have a high risk of bleeding. RESULTS: Among 3598 patients enrolled in the study, 29.2% were at high risk of bleeding (44.7% female; median [Q1-Q3] age 72 [65-81], CHA2DS2-VASc score 5 [4-6], HAS-BLED 3 [3-4]). In this group, 14.5% of patients did not receive OACs, 68% received NOACs, and 17.5% VKAs. In multivariable analysis, the independent predictors of nonuse of oral OACs were as follows: creatinine level (odds ratio [OR], 1.441; 95% confidence interval [CI], 1.174-1.768; P <0.001), a history of gastrointestinal bleeding (OR, 2.918; 95% CI, 1.395-6.103; P = 0.004), malignant neoplasm (OR, 3.127; 95% CI, 1.332-7.343; P = 0.009), and a history of strokes or transient ischemic attacks (OR, 0.327; 95% CI, 0.166-0.642; P = 0.001). CONCLUSIONS: OACs were used much less frequently in the group with a high HAS-BLED score than in the group with a low score. Independent predictors of nonuse of OACs were creatinine levels, a history of gastrointestinal bleeding, and malignant neoplasms. A history of stroke or transient ischemic attack increased the chances of receiving therapy.

BACKGROUND: Most atrial fibrillation (AF) patients are at high risk of thromboembolic, and the use of oral anticoagulants (OACs) is advised in such cases. The aim of the study was to evaluate the frequency at which OACs were used in patients with AF and high risk thromboembolic complications, and identify factors that result in OACs not being used in the researched group of patients. METHODS: The prospective, multicenter and non-interventional POL-AF registry is a study that includes AF patients from ten Polish cardiology centers. They were consecutively hospitalized between January and December of 2019. All the patients in the study were of high stroke risk. RESULTS: A total of 3614 patients with AF and high stroke risk were included. Among the total study population, 91.5% received OAC therapy; antiplatelet therapy was prescribed for 3.7% of patients, heparin for 2.7%, and 2.1% of patients did not receive any stroke prevention therapy. Independent predictors of no OAC prescription were intracranial bleeding (OR 0.15, 95%CI 0.07-0.35, p < 0.001), gastrointestinal bleeding (OR 0.25, 95%CI 0.17-0.37, p < 0.001), cancer (OR 0.37, 95%CI 0.25-0.55, p < 0.001), hospitalization due to acute coronary syndrome (OR 0.48, 95%CI 0.33-0.69, p < 0.001), and anemia (OR 0.62, 95%CI 0.48-0.81, p < 0.001). CONCLUSIONS: Most AF patients with a high thromboembolic risk received OACs. The factors predisposing a lack of OAC use in these patients were conditions that significantly increased the risk of bleeding complications.
RESUMO
<b>Introduction:</b> Tumors which most frequently metastasize to the heart include: malignant melanoma, lung cancer, breast cancer, ovarian cancer, kidney cancer, leukemia, lymphomas and esophageal cancer. <br><b>Purpose:</b> The purpose of this paper was clinical analysis of a group of patients operated in deep hypothermic circulatory arrest due to tumors of the right atrium and the inferior vena cava. <br><b>Material and method:</b> The study covered 7 patients operated at the Cardiac Surgery Clinic with a cardiac tumor diagnosed on the basis of an echocardiographic assessment in the years 2012-2019. Before qualifying for surgical treatment, each patient underwent: thorough interview and physical examination, 12-lead ECG, laboratory tests and echocardiography. Patients additionally underwent: computed tomography of the chest or abdomen, magnetic resonance imaging and coronary angiography on the basis of which patients with significant coronary artery changes underwent simultaneous coronary artery bypass graft. After preparation, the tumor was excised from the vena cava and right atrium with simultaneous removal of the primary tumor, most often kidney cancer. Early and distant results of treatment were analyzed in the examined group of patients to determine the following endpoints: hospital mortality and survival after surgery: after 3 months and 12 months. <br><b>Results:</b> Of all operated patients: 2 individuals died in the early postoperative period due to hemorrhagic complications (hospital mortality - 28.6%), and 5 patients (71.4%) were discharged from the Clinic in a good general condition. In total, 3-month survival was 71.4%, and 12-month survival amounted to 28.6%. <br><b>Conclusions:</b> Surgeries are very complex and challenging, and usually take on average 8-10 hours. It can improve the outcomes of palliative oncological treatment, better physical function (cardiovascular fitness) and extend life from several months to several years in more than ²/3 patients.
