Introduction: COVID-19 generates a wide range of clinical manifestations in general. In patients with rheumatic diseases, in addition to respiratory manifestations, joint, dermatological, general and cardiovascular manifestations, among others, stand out. Objective: to identify the cardiovascular manifestations that most frequently occur in patients with rheumatic diseases and COVID-19. Methodology: a basic, non-experimental research was carried out, with an exploratory, descriptive and explanatory scope. Universe made up of 37 patients with a previous diagnosis of rheumatic disease and a confirmed diagnosis of COVID-19. Directed observation and documentary review were used as research techniques to identify the presence of cardiovascular manifestations in this type of patient. Results: Predominance of female patients (59.56 %), diagnosed with osteoarthritis (72.97 %) and rheumatoid arthritis (72.97 %) and with associated comorbidities (83.78 %). Hypertension (61.29 %) and hypothyroidism (38.71 %) were the most frequent comorbidities. 70.27 % of the patients presented cardiovascular manifestations, predominantly arterial hypertension (65.38 %), rhythm disorders (57.69 %) and Raynaud's syndrome (53.85 %). 80.0 % of the male patients presented cardiovascular manifestations, as did 80.64 % of the cases with rheumatic disease, COVID-19 and associated comorbidities. Conclusions: Cardiovascular manifestations occurred with high frequency in rheumatic patients diagnosed with COVID-19; being more frequent in male patients and with associated comorbidities. High blood pressure, rhythm disorders and Raynaud's syndrome were the most frequent.
