Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen responsible for the novel coronavirus disease 2019 (COVID-19). The first reports of COVID-19 came from Wuhan, China in December of 2019. Since then, the disease has spread rapidly around the globe, accounting for thousands of deaths in multiple countries. On March 11th, 2020, the World Health Organization declared COVID-19 as a pandemic. Although COVID-19 manifests primarily as a respiratory illness, several cardiovascular implications have been reported related to its natural course and treatment. Its exact effect on the cardiovascular system though is currently unknown. Therefore, we propose a retrospective, observational, case-control study looking for cardiovascular manifestations of COVID-19, including laboratory evidence of myocardial injury, electrocardiographic changes, arrhythmias and echocardiographic abnormalities. Hospitalized patients admitted with fever, cough, sore throat, and/or dyspnea who were tested positive for SARS-CoV-2 will be included in our study and will be matched based on their age and gender with patients admitted with similar symptoms who tested negative for SARS-CoV-2. The electronic medical charts of the study subjects will be reviewed and relevant demographic, clinical, laboratory and imaging findings will be deidentified and recorded. Since our study will be a retrospective chart review study it carries minimal risk for the patients and the investigators. Cardiovascular disease associated with COVID-19 might be contributing to the high mortality rates and its recognition will allow for prevention, early diagnosis and appropriate treatment. This will be the first, large, case-control study assessing cardiovascular involvement of COVID-19 in a well-defined cohort of patients.

Description

Significance

Coronavirus disease 2019 (COVID-19) is a rapidly spreading infection that has already affected close to a million patients around the world. It is estimated that COVID-19 will be lethal for up to 200,000 Americans. Several cardiovascular manifestations have been reported to be associated with the disease or its treatment and might be contributing to its high mortality rates.1,2 The National Health Commission of China (NHC) documented that approximately 12% of patients without prior cardiovascular disease (CVD) who expired in the setting of COVID-19 had either elevated cardiac troponin I levels or a cardiac arrest during hospitalization.3 Furthermore, patients with underlying cardiovascular comorbidities experience worse outcomes when infected with SARS-CoV-2.1 Acute myocarditis, acute myocardial injury, and heart failure have been associated with COVID-19.3 However, most of these associations come from small observational studies or from comparisons with other coronaviruses.3 The hypothesized pathogenetic mechanism of CVD in COVID-19 includes either direct effects of the virus to the cardiac cells expressing the angiotensin- converting enzyme 2 (ACE2) receptor, or indirect effects from the severe systemic inflammatory response, cytokine surge and immune system activation. The exact effect of COVID-19 on the cardiovascular system though is still not well known. This study seeks to identify the prevalence of CVD and its role in clinical outcomes of hospitalized patients diagnosed with COVID-19 in a large tertiary center of Houston, TX. CVD associated with COVID-19 might be contributing to the high mortality rates and its recognition will allow for prevention, early diagnosis and appropriate treatment. This will be the first, large, case-control study assessing cardiovascular involvement of COVID-19 in a well-defined cohort of patients.

Methods

Study population and data handling:

A retrospective observational case-control study will be performed. Multiple hospitals will participate in the current study and the study protocol will be submitted separately to each local IRB for approval. Subjects admitted to the participating hospitals from March 30th, 2020 to March 30th, 2021, who were tested for SARS-CoV-2 by PCR will be identified through the microbiology lab registry. Subjects who were tested positive for SARS-CoV-2 by PCR will be age- and gender-matched with subjects admitted to the hospital with similar symptoms but negative PCR tests for SARS-CoV-2 (one negative PCR test for patients of low clinical suspicion and two negative tests, 24 hours apart from each other, for patients of high clinical suspicion). Demographic, clinical, laboratory and imaging findings will be collected by retrospective electronic chart review. The current study will not involve face-to-face patient contact and does not intent to alter the usual care of the patients involved. The collected data will be deidentified and stored in a HIPAA approved, password-secured designated folder of the UTH-share drive of the University of Texas Health Science Center at Houston. No patient information will be stored or processed in any personal electronic devices. A total of 500 study subjects are estimated to be included in the study. Upon completion of the study, the data will be stored for an additional 5 years; following that all research-related files will be permanently deleted.

Data collection:

Demographic characteristics including age at the time of diagnosis, gender, race and body mass index will be collected. Past medical history including coronary artery disease, heart failure with reduced or preserved ejection fraction, atrial fibrillation, hypertension, dyslipidemia, diabetes mellitus, smoking status as well as home medications will be abstracted. The name and daily dose of ACE inhibitors or angiotensin receptor blockers will be recorded. Laboratory values including cardiac enzymes, electrolytes, hemoglobin and creatinine will be collected. Available electrocardiograms (EKGs) and transthoracic echocardiograms (TTEs) will be individually reviewed by an independent cardiovascular disease fellow or a cardiovascular disease faculty member who will be blinded to the SARS-CoV-2 PCR results. Finally, clinical outcomes including need for mechanical ventilation, length of intensive care unit stay, length of hospitalization, arrhythmias, cardiac arrest and in-hospital mortality will be abstracted from the electronic charts.

Statistical analysis:

Continuous variables will be tested for distribution. Normally distributed variables will be presented as mean values +/- standard deviation (SD) and compared using the student's t test. Non-normally distributed variables will be presented as median values with interquartile ranges and compared using the Mann-Whitney test. Categorical variables will be presented as percentages and compared using chi-square test. Multivariable regression analysis will be performed to control for possible cofounder. A two-sided p-value of less than 0.05 will be considered statistically significant. All statistical analyses will be performed using STATA 15 (StataCorp, College Station, TX).
