The effect of COVID-19 pandemic on myocardial infarction care and on its prognosis - Experience at a high volume Hungarian cardiovascular center.

Introduction: The COVID-19 pandemic has impacted many aspects of acute myocardial infarction. Based on literature data, the prognosis of COVID+, STEMI patients is significantly worse than that of COVID- STEMI patients. On the other hand, physicians report fewer acute coronary syndrome (ACS) patients presenting to hospitals in countries severely affected by the pandemic. It is concerning that patients with life-threatening illness can suffer more complications or die due to their myocardial infarction. We aimed to investigate the changes in myocardial infarction care in the country's biggest PCI-center and to compare total 30-day mortality in COVID+ and COVID-patients with acute myocardial infarction treated at the Semmelweis University Heart and Vascular Center, and to investigate risk factors and complications in these two groups. Methods: Between 8 October 2020 and 30 April 2021, 43 COVID+, in 2018-2019, 397 COVID-patients with acute myocardial infarction were admitted. Total admission rates pre- and during the pandemic were compared. Results: Within 30 days, 8 of 43 patients in the COVID+ group (18.60%), and 40 of the 397 patients in the control group (10.07%) died (P = 0.01). Regarding the comorbidities, more than half of COVID+ patients had a significantly reduced ejection fraction (EF≤ 40%), and the prevalence of heart failure was significantly higher in this group (51.16% vs. 27.84%, P = 0.0329). There was no significant difference between the two patient groups in the incidence of STEMI and NSTEMI. Although there was no significant difference, VF (11.63% vs. 6.82%), resuscitation (23.26% vs. 10.08%), and ECMO implantation (2.38% vs. 1.26%) were more common in the COVID+ group. The mean age was 68.8 years in the COVID+ group and 67.6 years in the control group. The max. Troponin also did not differ significantly between the two groups (1,620 vs. 1,470 ng/L). There was a significant decline in admission rates in the first as well as in the second wave of the pandemic. Conclusions: The 30-day total mortality of COVID+ patients was significantly higher, and a more severe proceeding of acute myocardial infarction and a higher incidence of complications can be observed. As the secondary negative effect of the pandemic serious decline in admission rates can be detected.

The associations of long-COVID symptoms, clinical characteristics and affective psychological constructs in a non-hospitalized cohort.

Objective: The effects of COVID-19, especially long-COVID, on the psychological health is incompletely understood. We aimed to evaluate the mid-term associations of the long-COVID symptoms and affective factors in a cohort of non-hospitalized patients. Method: A total of 166 patients were enrolled in this study, including 119 sedentary/non-athlete and 47 athlete subjects at the Post-COVID Outpatient Clinic of Semmelweis University. Clinical data regarding acute and long-term symptoms were obtained and detailed laboratory testing was carried out. Demographic data and psychological tests were collected. Results: We found a positive association between the level of depressive symptoms and anxiety and long-COVID symptom count, while life satisfaction and social support correlated negatively with the long-COVID symptom count. Higher haemoglobin levels and lower LDL-cholesterol were also shown to be moderating factors. A regression model showed that symptoms during acute infection, depression, age, and life satisfaction are predictors of the long-COVID symptom count. The presence of pre-existing affective or anxiety problems was also associated with higher reported long-COVID symptom count. Furthermore, we found significant association between pre-existing mental health problems and the investigated psychological constructs. Conclusion: It appears that long COVID-19 is associated with acute symptoms and mental factors. Depression and anxiety have been shown to have a negative effect on symptom perception, and also contribute to a higher number of symptoms in a non-hospitalized sample. Our study suggests bi-directional interconnection between clinical and psychological factors.
