Voice and prosody disorders are among the abnormalities that accompany selected systemic diseases, including lifestyle diseases. In this second group of dysfunctions, circulatory system diseases occupy a high position. Attempts to determine not only primary, but also secondary disorders and their causes are part of activities providing highly specialized cardiological care, but also support the implementation of possible rehabilitation activities – currently largely including physiotherapy. One of the basic disorders coexisting with cardiovascular diseases are breathing dysfunctions, which in turn reduces the quality of communication – voice formation and the use of the prosodic layer of speech. The text presents the results of a survey conducted on a group of 90 people diagnosed with cardiovascular diseases. The aim of the procedure was to determine whether the respondents had voice, prosody and breathing disorders, which of them occurred during the course of the disease and whether they constitute a factor that, according to the respondents, reduces the quality of their expression and communication. The survey results allow for the identification of the dominant and less frequently occurring disorders in people with cardiovascular diseases.
