Cardiovascular complications are the primary drivers of mortality in hospitalized patients with SARS-CoV-2 community-acquired pneumonia.

BACKGROUND: Hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) community-acquired pneumonia (CAP) and associated comorbidities are at increased risk of cardiovascular complications. The magnitude of effect of cardiovascular complications and the role of prior comorbidities on clinical outcomes are not well defined. RESEARCH QUESTION: What is the impact of cardiovascular complications on mortality in hospitalized patients with SARS-CoV-2 CAP? What is the impact of co-morbidities and other risk factors on the risk of developing cardiovascular complications and mortality in these patients? STUDY DESIGN AND METHODS: This cohort study included 1,645 hospitalized patients with SARS-CoV-2 CAP. Cardiovascular complications were evaluated. The clinical course during hospitalization was described using a multistate model with 4 states: hospitalized with no cardiovascular complications, hospitalized with cardiovascular complications, discharged alive, and dead. Cox proportional hazards regression was used to analyze the impact of prior comorbid conditions on transitions between these states. Hazard ratios (HRs) and 95% confidence intervals (CIs) were reported. RESULTS: Cardiovascular complications occurred in 18% of patients hospitalized with SARS-CoV-2 CAP. The mortality rate in this group was 45% versus 13% in patients without cardiovascular complications. Males (HR: 1.32, 95% CI: 1.03-1.68), older adults (HR: 1.34, 95% CI: 1.03-1.75), patients with congestive heart failure (HR: 1.59, 95% CI: 1.18-2.15), coronary artery disease (HR: 1.34, 95% CI: 1.00-1.79), atrial fibrillation (HR: 1.43, 95% CI: 1.06-1.95), direct admissions to the ICU (HR: 1.77, 95% CI: 1.36-2.32) and PaO2/FiO2 less than 200 (HR: 1.46, 95% CI: 1.11-1.92) were more likely to develop cardiovascular complications after hospitalization for SARS-CoV-2 CAP; however, these factors are not associated with increased risk of death after a cardiovascular complication.

Impact of Hyperglycemia on Cardiovascular Events and Clinical Outcomes in Patients Hospitalized With COVID-19 Pneumonia.

OBJECTIVE: To study cardiovascular events and clinical outcomes in patients with elevated glycated hemoglobin (HbA1c) levels and/or admission hyperglycemia and those with type 2 diabetes hospitalized with SARS-CoV-2 pneumonia. METHODS: This was a multicenter retrospective study of 1645 patients hospitalized with SARS-CoV-2 pneumonia. Diagnosis of SARS-CoV-2 pneumonia required a positive reverse transcription-polymerase chain reaction result for SARS-CoV-2, presence of new or worsening pulmonary infiltrates on computed tomography scan or chest x-ray, and at least one of following: (1) new or increased cough, (2) temperature of >37.8 °C, or (3) dyspnea. Outcomes included in-hospital cardiovascular events, intensive care unit admission, and mortality. Logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for association of elevated HbA1c levels and/or admission hyperglycemia and type 2 diabetes for individual outcomes. RESULTS: Among 1645 adults hospitalized with SARS-CoV-2 pneumonia, 18 with type 1 diabetes were excluded from the analysis. Of 1627 adults, 634 (39%) had known diagnosis of type 2 diabetes, and among 993 patients with no diabetes, 107 (10.8%) patients were identified with elevated HbA1c levels and/or admission hyperglycemia. Patients with elevated HbA1c levels and/or admission hyperglycemia had increased odds of developing acute in-hospital cardiovascular events (OR, 1.73; 95% CI, 1.07-2.80), intensive care unit admissions (OR, 1.61; 95% CI, 1.10-2.34), and mortality (OR, 1.77; 95% CI, 1.02-3.07) compared to patients with type 2 diabetes and no diabetes. CONCLUSION: Patients with elevated HbA1c levels and/or admission hyperglycemia hospitalized with SARS-CoV-2 pneumonia have increased risk of developing acute in-hospital cardiovascular complications and overall poor clinical outcomes compared with patients with type 2 diabetes and no diabetes.

Clinical outcomes in patients with COPD hospitalized with SARS-CoV-2 versus non- SARS-CoV-2 community-acquired pneumonia.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) have poor outcomes in the setting of community-acquired pneumonia (CAP) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The primary objective is to compare outcomes of SARS-CoV-2 CAP and non-SARS-CoV-2 CAP in patients with COPD. The secondary objective is to compare outcomes of SARS-CoV-2 CAP with and without COPD. METHODS: In this analysis of two observational studies, three cohorts were analyzed: (1) patients with COPD and SARS-CoV-2 CAP; (2) patients with COPD and non-SARS-CoV-2 CAP; and (3) patients with SARS-CoV-2 CAP without COPD. Outcomes included length of stay, ICU admission, cardiac events, and in-hospital mortality. RESULTS: Ninety-six patients with COPD and SARS-CoV-2 CAP were compared to 1129 patients with COPD and non-SARS-CoV-2 CAP. 536 patients without COPD and SARS-CoV-2 CAP were analyzed for the secondary objective. Patients with COPD and SARS-CoV-2 CAP had longer hospital stay (15 vs 5 days, p < 0.001), 4.98 higher odds of cardiac events (95% CI: 3.74-6.69), and 7.31 higher odds of death (95% CI: 5.36-10.12) in comparison to patients with COPD and non-SARS-CoV-2 CAP. In patients with SARS-CoV-2 CAP, presence of COPD was associated with 1.74 (95% CI: 1.39-2.19) higher odds of ICU admission and 1.47 (95% CI: 1.05-2.05) higher odds of death. CONCLUSION: In patients with COPD and CAP, presence of SARS-CoV-2 as an etiologic agent is associated with more cardiovascular events, longer hospital stay, and seven-fold increase in mortality. In patients with SARS-CoV-2 CAP, presence of COPD is associated with 1.5-fold increase in mortality.

Anticancer Therapy in COViD-19 Patients: A Descriptive Literature Review.

OBJECTIVE: To provide a descriptive literature review about the effects of anticancer treatment on clinical outcomes because of active COVID-19 infection in older people. DATA SOURCES: A literature search was conducted in Google Scholar, PubMed, American Society of Clinical Oncology, European Society for Medical Oncology, and the Center for Disease Control and Prevention. Articles published in English between December 1, 2019, to September 1, 2020, were included. STUDY SELECTION: Nine studies assessing the effectiveness of various modalities for cancer treatments in patients infected with COVID-19 infection were reviewed. The studies reviewed the severity of COVID-19 infection outcomes in patients who underwent any anticancer treatment. Studies exclusively focused on older people could not be found, but all studies included older people. DATA SYNTHESiS AND RESULTS: Early pandemic studies suggested avoiding anticancer treatment during a COVID-19 infection because of poor clinical outcomes and increased mortality. However, the totality of studies reviewed found no association between the continuation of anticancer treatment and adverse COVID-19 outcomes in cancer patients. Adverse COVID-19 infection outcomes and high mortality rates were associated with older cancer patients independent of anticancer therapy. CONCLUSION: Treatment of cancer could be challenging because of the COVID-19 pandemic. Interruption or delaying the anticancer therapy could increase the burden of overall mortality. This literature review indicated that adverse outcomes because of COVID-19 are associated with advanced age independent of anticancer therapy. Further exploration of the correlation between cancer, anticancer treatments, and COVID-19 infection outcomes is needed.
