Background and Aims Right heart catheterization is a fundamental tool for the diagnosis, management and prognosis of pulmonary hypertension, as well as necessary in the prior evaluation of receptors for heart transplantation. The main aim is to determine if therapeutic anticoagulation represents a risk factor for the development of bleeding complications secondary to this technique in a third-level hospital.
Methods The study design is an observational retrospective study, collecting data from patients undergoing a right heart catheterization between 2017 and 2020. A non-random sampling of consecutive cases is carried out for the study, obtaining a sample made up of 309 subjects with a confidence level of 95% and a margin of error of 5%. All patients gave their signed written consent. Statistical analysis of the collected data was carried out using the statistical package R version 4.1.
Results The incidence of intraprocedural complications was 5.57% and postprocedural was 1.97%, being slightly higher in relative terms in the group of patients without anticoagulant treatment (5.71% and 2.86%, respectively). However, there were not found significative statiscally differences, obtaining a p-value of 0.9215 for intraprocedural complications and 0.3062 for complications which took place after the catheterization. These complications are, to the greatest extent, operator-dependent, a consequence of technical errors attributable to the procedure itself rather than to other underlying factors.
Conclusions The anticoagulant treatment do not represent a risk factor for the development of bleeding complications in patients who undergo a right heart catheterization.
