Introduction: Acute Coronary Syndrome (ACS) is one of the most common causes of death in patients with Cardiovascular Diseases (CVD). In addition to the known physical factors influencing the incidence of CVD, some psychologists have pointed to the role of psychological factors such as personality type. Objective: This study aimed to determine the role of type D personality in ACS patients in Iran in 2019. Materials and Methods: In a case-control study, 112 participants were included. A total of 56 patients with ACS were compared with 56 matched people without ACS. They were selected by the convenience sampling method. Type D scale 14 (DS14) was used to assess the type D personality. The Chi-squared test, independent t-test, and multivariate logistic regression were used to analyze the obtained data. Results: The Mean±SD age in the case group was 57.23±8.562 years, and in the Mean±SD age in the control group was 57.25±8.529 years. Also, most participants in both groups were men (71.4%). The result showed that type D personality was more prevalent in patients with ACS (26% vs 7.1%; P=0.006). Based on multivariate regression analysis and after controlling for demographic and clinical risk factors, type D personality was independently associated with ACS (OR=5.323, 95% CI; 0.987-28/712, P=0.052). Also, after investigating subscales, only social inhibition had a significant association with ACS (P=0.008). Conclusion: Type D personality is an independent risk factor of the ACS. Thus, type D personality may make people vulnerable to the ACS. Therefore, besides medical interventions, clinicians must consider behavioral interventions to reduce the incidence of ACS.

Introduction: SARS-Covid 2 is a new type of coronavirus which is a serious threat to all countries. Identifying the risk factors and investigating cases between deaths and discharge can increase public awareness to deal with this virus more easily. Methods: We conducted a case-control study on 274 patients with COVID-19 between March 1, 2020, and April 30, 2020. The cases were 137 COVID-19 patients discharged from the hospital, and the controls were patients who died due to COVID-19. Patient's information was obtained with demographic, clinical risk factors questionnaire, and their medical records. Result: The results showed that the age over 70, overweight, and high body mass index were significant predictors of death due to COVID-19. Opium use was associated with the death of COVID-19; however, it was not a significant predictor as an independent variable. Histories of chronic disease, as well as clinical signs of dyspnea, were significantly associated with death due to COVID-19. Fever and myalgia were introduced as the supportive clinical signs, so fever and myalgia were significantly more common in discharged individuals. Conclusion: Given that in this study, age over 70, overweight, obesity, opium use, and having clinical symptoms such as chronic diseases and dyspnea have been introduced as the risk factors for death due to COVID-19, so it is recommended due to lack of access to the appropriate vaccine to prevent COVID-19, during the outbreak of the virus. To prevent infection and spread of the virus, further training is required in the use of face masks, reducing traffic in public places, and proper handwashing.
