Clinical characteristics and 12-month outcomes of patients with myocardial infarction with nonobstructive coronary arteries before and during the COVID-19 pandemic.

INTRODUCTION: SARS­CoV­2 infection is associated with an increased risk of thromboembolic complications. Thromboembolism is one of the possible causes of myocardial infarction with nonobstructive coronary arteries (MINOCA). OBJECTIVES: We aimed to compare the characteristics and 12­month clinical outcomes of patients with MINOCA treated before and during the COVID­19 pandemic. PATIENTS AND METHODS: We retrospectively analyzed data of 51 734 patients with acute myocardial infarction registered in the nationwide Polish Registry of Acute Coronary Syndromes database in 2019 and 2020. The final study group included 3178 patients with MINOCA. We compared the baseline characteristics, management strategies, and 12­month clinical outcomes of the MINOCA patients treated before (2019) and during the COVID­19 pandemic (2020). RESULTS: The rate of MINOCA was higher in 2019 than in 2020 (6.3% vs 5.9%; P = 0.03). The only difference between the groups was a higher hypercholesterolemia rate before the pandemic (33.9% vs 28.2%; P <0.001). In­hospital stroke was observed more frequently during the pandemic (0% vs 0.3%; P = 0.01), whereas other in­hospital complications were similar between the groups. Most patients were discharged on aspirin (85.6%), a ß­blocker (73.1%), an angiotensin­converting enzyme inhibitor / angiotensin receptor blocker (70.2%), and a statin (62.7%), but only 50.6% of the participants received a P2Y12 inhibitor. There was no difference in 12­month all­cause mortality between the patients with MINOCA treated before and during the pandemic (9.2% vs 11%; P = 0.09). CONCLUSIONS: We observed a lower percentage of MINOCA cases and higher in­hospital stroke rates in the MINOCA patients treated during the COVID­19 pandemic (2020). The possible association between worse clinical outcomes of the MINOCA patients treated during the pandemic and the increased risk for thromboembolic complications of SARS­CoV­2 infection needs further evaluation.

Comparison of reorganized versus unaltered cardiology departments during the COVID-19 era: A subanalysis of the COV-HF-SIRIO 6 study.

BACKGROUND: Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, numerous cardiology departments were reorganized to provide care for COVID-19 patients. We aimed to compare the impact of the COVID-19 pandemic on hospital admissions and in-hospital mortality in reorganized vs. unaltered cardiology departments. METHODS: The present research is a subanalysis of a multicenter retrospective COV-HF-SIRIO 6 study that includes all patients (n = 101,433) hospitalized in 24 cardiology departments in Poland between January 1, 2019 and December 31, 2020, with a focus on patients with acute heart failure (AHF). RESULTS: Reduction of all-cause hospitalizations was 50.6% vs. 21.3% for reorganized vs. unaltered cardiology departments in 2020 vs. 2019, respectively (p < 0.0001). Considering AHF alone respective reductions by 46.5% and 15.2% were registered (p < 0.0001). A higher percentage of patients was brought in by ambulance to reorganized vs. unaltered cardiology departments (51.7% vs. 34.6%; p < 0.0001) alongside with a lower rate of self-referrals (45.7% vs. 58.4%; p < 0.0001). The rate of all-cause in-hospital mortality in AHF patients was higher in reorganized than unaltered cardiology departments (10.9% vs. 6.4%; p < 0.0001). After the exclusion of patients with concomitant COVID-19, the mortality rates did not differ significantly (6.9% vs. 6.4%; p = 0.55). CONCLUSIONS: A greater reduction in hospital admissions in 2020 vs. 2019, higher rates of patients brought by ambulance together with lower rates of self-referrals and higher all-cause in-hospital mortality for AHF due to COVID-19 related deaths were observed in cardiology departments reorganized to provide care for COVID-19 patients vs. unaltered ones.

Prevalence of Insomnia in the Early Post-COVID-19 Recovery Period.

BACKGROUND: Sleep is a complex, reversible process that is responsible for the modulation of various physiological mechanisms. COVID-19-related sleep disorders are affecting different populations with a heterogenous prevalence, yet high rates among infected patients are frequently reported. The aim of the study is to assess the prevalence of insomnia in the early post-COVID-19 recovery period and explore the differences in the results acquired by the Athens Insomnia Scale (AIS) by gender and selected infection severity parameters. METHODS: The data presented in the paper come from a prospective, observational study on COVID-19 complications (SILCOV-19) consisting of 200 COVID-19 patients. The AIS was used for the quantitative measurement of insomnia symptoms based on ICD-10 criteria. RESULTS: 32% (n = 64) of all patients in the study group obtained results indicating sleep disturbances (>5 points on the scale), while 21.5% (n = 43) obtained results indicating insomnia (>10 points on the scale). The analysis of the results obtained by all patients in the AIS showed a significant correlation with the duration of symptoms (Spearman's rank-order: R = 0.18; p < 0.05), but not with the number of days spent in the hospital or age. Women achieved a higher score in overall AIS, as well as in questions assessing total sleep time, well-being the next day, physical and mental fitness the next day, and sleepiness during the day (p < 0.05). CONCLUSIONS: the prevalence of insomnia in the early post-COVID-19 recovery period is high.

Post-COVID­19 complications in hospitalized and nonhospitalized patients: the Silesian database of COVID­19 complications (SILCOV­19).

INTRODUCTION: Due to the extent of the pandemic, high prevalence and severity of complications in the early post­recovery period are expected. OBJECTIVES: This study aimed to compare the scope of early post-COVID­19 complications in patients who had the disease and were or were not hospitalized. PATIENTS AND METHODS: This was a prospective, observational, registry­based cohort study conducted at a tertiary cardiovascular hospital in Silesia, Poland. Interdisciplinary diagnostics, including cardiovascular, pneumatological, respiratory, neurological, and psychiatric tests, was performed during the study visit. All patients completed the study. Two­hundred unselected, adult, white men and women with the symptoms of acute COVID­19 were included, of which 86 patients had the disease but did not require hospitalization. RESULTS: The median (interquartile range) time from symptom onset to the study visit was 107 (87-117) and 105 (79-127) days in nonhospitalized and hospitalized patients, respectively. Lung lesions on high­resolution computed tomography were found in 10 (8.8%) and 33 (39.3%) of nonhospitalized and hospitalized patients, respectively (P <0.01); no lesions were visualized on chest X­ray images. Elevated platelet distribution width was found in more than 70% of the patients in both groups. More than half of the patients had insomnia, regardless of the hospitalization status. CONCLUSIONS: The abnormal platelet parameters, functional and radiological findings in the lungs, and insomnia were the most frequent short­term COVID­19 complications in hospitalized and nonhospitalized patients. Considering the number of patients who have had COVID­19 worldwide, a high burden of the post-COVID­19 complications might be expected.

Assessment of the Level of Anxiety for COVID-19 Vaccinations.

Research published especially in the last decade indicates the influence of anxiety on the human decision-making process. This study analyzes the anxiety among individuals who decided to undergo vaccinations for COVID-19. The study assesses that the level of education, especially medical education, age, and gender, had an influence on the level of anxiety in terms of vaccination situations. The STAI self-assessment questionnaire was used. The study was conducted anonymously using the paper-pencil method during two rounds of vaccination; therefore, the respondent sample included mainly medical personnel and elderly people. A total of 898 questionnaires were issued. Age did not affect the trait and state of anxiety, but highly educated people tested during vaccination had a lower anxiety level. Gender had no influence on the trait but did influence the state of anxiety. Overall, women were the group that exhibited a higher level of anxiety than men. Nurses were particularly vulnerable to the negative effects of situational medication in this group.

Cardiac implantable electronic devices procedures and their recipients characteristic during COVID-19 pandemic: 3.8 million population analysis.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic disorganised healthcare systems and has caused a reduction in the number of hospitalizations and procedures. Cardiac implantable electronic device (CIED) procedure rates and clinical characteristics of their recipients were compared in corresponding weeks of 2019 and 2020 were analyzed. METHODS: The database of the National Health Fund (NHF) in Poland was retrospectively analyzed. 3206 patients who underwent CIED implantation in the Silesia - a region in Southern Poland comprising an adult population of 3.8 million between 12th and 31st week of 2020. Patients were classified into groups: the recipient of an implantable cardioverter-defibrillator or cardiac resynchronization therapy group (ICD/CRT) or pacemaker group (PM). RESULTS: During the pandemic a reduction of 39.38% of implantations was observed compared to the same period in 2019 (1210 vs. 1996 patients) and had impacted both groups. Two phases lasting 10 weeks each could be distinguished: total lockdown (maximal reduction) and the recovery phase with growing numbers of procedures. Patient baseline characteristics (sex, age, comorbidities) who were implanted during the COVID-19 pandemic did not differ from the 2019 period. The rate of peri-procedural mortality was also similar. CONCLUSIONS: During COVID-19 pandemic period a reduction in CIED implantations of all types was observed. Despite the decreased number of performed CIED implants, no differences in baseline patient characteristics were observed.

Impact of COVID-19 pandemic on acute heart failure admissions and mortality: a multicentre study (COV-HF-SIRIO 6 study).

AIMS: The coronavirus disease-2019 (COVID-19) pandemic has changed the landscape of medical care delivery worldwide. We aimed to assess the influence of COVID-19 pandemic on hospital admissions and in-hospital mortality rate in patients with acute heart failure (AHF) in a retrospective, multicentre study. METHODS AND RESULTS: From 1 January 2019 to 31 December 2020, a total of 101 433 patients were hospitalized in 24 Cardiology Departments in Poland. The number of patients admitted due to AHF decreased by 23.4% from 9853 in 2019 to 7546 in 2020 (P < 0.001). We noted a significant reduction of self-referrals in the times of COVID-19 pandemic accounting 27.8% (P < 0.001), with increased number of AHF patients brought by an ambulance by 15.9% (P < 0.001). The length of hospital stay was overall similar (7.7 ± 2.8 vs. 8.2 ± 3.7 days; P = not significant). The in-hospital all-cause mortality in AHF patients was 444 (5.2%) in 2019 vs. 406 (6.5%) in 2020 (P < 0.001). A total number of AHF patients with concomitant COVID-19 was 239 (3.2% of AHF patients hospitalized in 2020). The rate of in-hospital deaths in AHF patients with COVID-19 was extremely high accounting 31.4%, reaching up to 44.1% in the peak of the pandemic in November 2020. CONCLUSIONS: Our study indicates that the COVID-19 pandemic led to (i) reduced hospital admissions for AHF; (ii) decreased number of self-referred AHF patients and increased number of AHF patients brought by an ambulance; and (iii) increased in-hospital mortality for AHF with very high mortality rate for concomitant AHF and COVID-19.
