The role of pneumococcal vaccination in reducing cardiovascular risk in cardiac patients: Expert opinion of the Prevention Committee of the Polish Cardiac Society supported by the Polish Vaccinology Society

Respiratory diseases have been the fourth most common cause of death in Poland in recent years. Respiratory infection, especially pneumonia, can lead to exacerbation of chronic cardiovascular disease. Streptococcus pneumoniae is the most common bacterial pathogen causing community-acquired pneumonia. Pneumococci are also the most common pathogen complicating the course of infection with the influenza virus. Pneumonia, especially invasive pneumococcal disease, is associated with risk of death in the course of respiratory failure or sepsis and also with worsening of the prognosis for existing cardiovascular disease. Despite those facts, recommendations for pneumococcal vaccination are still not well established in cardiovascular guidelines. This expert opinion aims to summarize current knowledge on the importance of preventing invasive pneumococcal disease in cardiac patients
