comparison of the characteristics of coronavirus disease 2019 (covid-19) in dead and survived patients with heart failure: a retrospective study from northern iran

During coronavirus disease 2019 (covid-19), one of the comorbidities that can cause more severe negative clinical consequences than other patients are heart failure (hf) disease. this study aimed to assess and compare characteristics of covid-19 in dead or survived patients with hf. using a retrospective study, 78 hf patients with covid-19 referred to a heart center in northern iran were included. data gathering was performed via census sampling from august 2020 to 2021. the medical records of hf patients with covid-19 were assessed. chi-square and t-tests were used to assess the relationship between study variables. multiple logistic regression analysis was also applied to assess the relationships of clinical and demographic characteristics with in-hospital mortality. a total of 78 hf patients with covid-19 were included in this study. the mean ef, duration of hf, and blood pressure of the patients were 25.83 (sd=12.31), 3.79 (sd=2.10) years, and 126.65 (sd=24.67) mmhg, respectively. also, 74.36% and 30.77% of patients had hypertension/hypotension and angioplasty, respectively. finally, 55.13% of hf patients with covid-19 died. most of the dead (65.12%) were females but most of the survivors (68.57%) were males (p=0.003). mean blood pressure of dead patients was lower compared to survived patients (121.26 vs. 133.27 mmhg; p=0.032). age and blood pressure were predictors of in-hospital mortality in hf patients with covid-19. the odds of in-hospital mortality were higher in males compared with females (or=35.717; 95% ci: 2.676 to 476.690; p=0.007). also, the odds of in-hospital mortality increased with decreasing blood pressure (or=0.945; 95% ci: 0.900 to 0.993; p=0.024). therefore, health managers and policymakers should pay special attention to covid-19 patients with hf.
