    Coronavirus disease MESHD 2019 (COVID-19) is a global pandemic impacting nearly 170 countries/regions and millions of patients worldwide. Patients with acute myocardial infarction MESHD myocardial infarction HP ( AMI MESHD) still need to be treated at percutaneous coronary intervention (PCI) centers with relevant safety measures. This study was conducted to assess the therapeutic outcomes of PCI performed under the safety measures and normal conditions. AMI MESHD patients undergoing PCI between January 24 to April 30, 2020 were performed under safety measures for COVID-19. Patients received pulmonary computed tomography (CT) and underwent PCI in negative pressure ICU. Cardiac catheterization laboratory (CCL) staff and physicians worked with level Ⅲ personal protection. Demographic and clinical data, such as door-to-balloon (DTB) time, operation time, complications for patients in this period (NCP group) and the same period in 2019 (2019 group) were retrieved and analyzed. NCP and 2019 groups had 37 and 96 patients, respectively. There was no significant difference in age TRANS, gender TRANS, BMI and comorbidity between the two groups. DTB time and operation time were similar between the two groups (60.0 ± 12.39 vs 58.83 ± 12.85 min, p = 0.636; 61.46 ± 9.91 vs 62.55 ± 10.72 min, p = 0.592). Hospital stay time in NCP group was significantly shorter (6.78 ± 2.14 vs 8.85 ± 2.64 days, p < 0.001). The incidences of malignant arrhythmia MESHD arrhythmia HP and Takotsubo Syndrome MESHD in NCP group were higher than 2019 group significantly (16.22% vs 5.21%, p = 0.039; 10.81% vs 1.04% p = 0.008). During hospitalization and 3-month follow-up, the incidence of major adverse cardiovascular events and mortality in the two groups were statistically similar (35.13% vs 14.58%, p = 0.094; 16.22% vs 8.33%, p =0.184). Our analysis showed that safety measures undertaken in this hospital, including screening of COVID-19 infection MESHD and use of personal protection equipment for conducting PCI did not compromise the surgical outcome as compared with PCI under normal condition, although there were slight increases in incidence of malignant arrhythmia MESHD arrhythmia HP and Takotsubo Syndrome MESHD.

    Coronavirus disease 2019 (COVID-19) presents as the main cause of death MESHD, respiratory and heart failures MESHD, especially in the elderly TRANS, immunosuppressed, and those with cardiovascular comorbidities. Therefore, a better understanding of these findings is needed. A systematic review was carried out looking for articles published between December 2019 and May 2020 on the MEDLINE / PubMed search platform using the following descriptors: (((((((((" cardiovascular disease MESHD") OR ("acute myocardial infarction HP myocardial infarction MESHD")) OR (" coronary artery disease MESHD")) OR ("acute coronary syndrome MESHD")) OR (" atherosclerosis HP atherosclerosis MESHD")) OR (" cardiac insufficiency MESHD")) OR (" pericarditis HP pericarditis MESHD")) OR (" myocarditis HP myocarditis MESHD")) AND ("COVID-19")) OR ("SARS-CoV-2")and considering inclusion and exclusion criteria.40% of patients infected with SARS-CoV-2 had hypertension HP hypertension MESHD or other cardiovascular comorbidities, while 27% presented cardiovascular complications, mainly acute cardiac injury MESHD, arrhythmia HP arrhythmia MESHD and heart failure MESHD. The hypotheses of involvement of an intense inflammatory response, decreased HP immunity and greater expression of ACE2 in the heart, associated with more severe heart conditions, were discussed in this study. The increase in cardiac and inflammatory markers was associated with worse clinical outcomes and risk of death MESHD, confirming the need to evaluate them since admission to the hospital. The 10 articles analyzed presented as a limitation the small number of patients inserted, to the detriment of the pandemic state. We warned about the need for better clinical management of patients with cardiovascular comorbidities MESHD, and the importance of including this group among the first to be immunized, aiming at reducing the number of fatal cases due to infection MESHD. Studies with greater coverage are needed for a better comprehension of the topics discussed here.

    Background The novel severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) has subsequently spread worldwide. The number of death MESHD has increased rapidly. However, the possible risk factors that lead to death in critical inpatients with coronavirus disease MESHD 2019 (COVID-19) are not yet fully known. This study was to explore the risk factors for mortality of critical inpatients with COVID-19.Methods In this single-centered, retrospective study, we enrolled 113 critical patients with COVID-19 in Renmin Hospital of Wuhan University between Feb 1, 2020 and Mar 15, 2020. Data were collected using a standard method including clinical records and laboratory findings. Outcomes of survivors and death were compared.Results A total of 113 critical patients (from 29 to 95 years) with COVID-19 were recruited, 50 (44.25%) died and 63 recovered (55.75%). The proportion of patients with ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in the death group than the recovery group (24.0% vs 4.4%; p = 0.021), and was higher among myocardial damage MESHD cases than non-myocardial damage cases (26.1% vs 4.3%; p = 0.013). Multivariate analysis confirmed four independent predictors related to mortality of COVID-19: age > 70 yrs (HR 1.84, 95% CI 1.03–3.28), initial neutrophil count more than 6.5 × 109/L (HR 3.43, 95% CI 1.84–6.40), C-reactive protein greater more than 100 mg/L (HR 1.93, 95% CI 1.04–3.59), and lactate dehydrogenase more than 300 U/L (HR 2.90, 95% CI 1.26–6.67). Immunoglobulin treatment (HR 0.39, 95% CI 0.21–0.73) can reduce the risk of death MESHD. There was no significant difference in the QT interval between patients with and without hydroxychloroquine treatment.Conclusions Old age TRANS (> 70 years), neutrophilia HP, C-reactive protein greater more than 100 mg/L and lactate dehydrogenase more than 300 U/L are high-risk factors for mortality of critical patients with COVID-19. The incidence of ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in deceased patients than survivors.

    Importance: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections MESHD outbreak in China is now a global issue. There is only a limited understanding of the clinical characteristics of patients with SARS-CoV-2 infections MESHD is available.Objective:To describe the characteristics, management strategies, and outcomes of critically ill MESHD patients with SARS-CoV-2 infection MESHD.Design, Setting, and Patients: This is aretrospective, multi-center case series of 50 critically ill MESHD patients with confirmed SARS-CoV-2 infection MESHD who were admitted at Zhongnan Hospital of Wuhan University and Wuhan Pulmonary Hospital in Wuhan, China, from January 8 to February 9, 2020.Exposures:Documented Corona Virus Disease MESHD, 2019 (COVID-19).Main Outcome Measures: Demographic, clinical, laboratory, imaging data were collected along with management strategies, complications and outcomes of enrolled individuals. Results Fifty critically ill MESHD patients with SARS-CoV-2 infections MESHD were enrolled. Their median age TRANS was 62 (range, 29-92) [IQR,49.5-69.0] years, 68% were male TRANS, and 28 (56%) patients had comorbidities, the most common being hypertension HP hypertension MESHD. In this cohort, 20(40%) patients survived ,16(32%) patients died, and the rest remained hospitalized. The invasive mechanical ventilator was used in 36(72%) patients with 15(30%) of them requiring prone positioning, and 17(34%) switched to ECMO. The compliance scores of lungs (Cstat)on the day of ICU admission among survivors were higher than those in non-survivors [42.0(18.0-47.0), vs. 19.5(14.0-24.2), p=0.038].The blood SERO IL-6 levels and neutrophils counts at the first day of ICU admission were significantly higher in non-survivors compared to survivors [123.7(85.3-228.8), vs. 20.2(6.8-67.2) ng/ml, p=0.025 for IL-6, and 20.2(6.8-67.2) vs. 4.01(1.99-7.05) × 10⁹/L, p=0.02 for neutrophils counts].The heart rates, PaCO2, lung injury MESHD scale (LIS), and positive end-expiratory pressure levels were constantly higher for 10 days in non-survivors than those who survived (p<0.05). The frequency of vasopressor uses and neuromuscular blockers was higher in non-survivors from day 1 to day 10 compared to survivors (p<0.05). In the whole cohort, the most common complications were ARDS (97%), shock HP shock MESHD (44%), arrhythmia HP arrhythmia MESHD (38%), acute cardiac injury MESHD (26%), and acute kidney injury HP acute kidney injury MESHD (22%). A secondary bacterial infection MESHD was noted in 17(34%) patients. Univariate analysis indicated that lower lung complianceand higher neutrophil counts at the day of ICU admission were related to higher mortality (p-0.03, and 0.04, respectively)ConclusionWe demonstrated that SARS-CoV-2 infection MESHD-related critical illness predominantly affected old individuals with comorbidities and characterized by severe hypoxemic respiratory failure MESHD respiratory failure HP, often requiring prolonged mechanical ventilation and rescue therapies. Low lung compliance and persistently elevated PaCO2 indicated poor outcomes.
