Cardiac and Other Presentation and Clinical Outcomes of COVID-19 Pandemic among Different Ethnic and Religious Populations in the city of Jerusalem

Background: The COVID ‐ 19 pandemic is an ongoing global pandemic. Jerusalem with its 919,400 inhabitants has a wide variety of populations, of which 62% are Jews (36% ultra-orthodox; 64% non-ultraorthodox) and 38% Arabs which were largely affected by the pandemic. The aim of our study was to understand the different presentations, course and clinical outcomes in these different ethnical and cultural groups in Jerusalem in the COVID-19 pandemic. Methods: We performed a cohort study of all COVID-19 patients admitted between March 9 - July 16, 2020 to the two university medical centers in Jerusalem. Patients were divided according to their religion and ethnicity into 3 main groups: 1) Ultra-Orthodox Jews; 2) other (non-Ultra-Orthodox) Jews and 3) Arabs. Results: Six hundred and two patients comprised the study population. Of them the 361 (60%) were UltraOrthodox Jews; 166 (27.5%) non-Ultra-Orthodox Jews and 75 (12.5%) Arabs. The Arab patients were younger than the Ultra-Orthodox Jews and the non-Ultra-Orthodox Jews (51±18 year-old vs. 57±21 and 59±19, respectively, p<0.01), but suffered from signi�cantly more co-morbidities. Moreover, hemodynamic shock, ischemic ECG changes and pathological chest x-ray were all more frequent in the Ultra-Orthodox patients as compared the other groups of patients. Being an Ultra-Orthodox was independently associated with signi�cantly higher rate of Major Adverse Cardiovascular Events (MACE) [OR=1.96; 95% CI (1.03-3.71), p<0.05]. Age was the only independent risk factor associated with increased mortality rate [OR=1.10; 95% CI (1.07 - 1.13), p<0.001]. Conclusions: The COVID-19 �rst phase in Jerusalem, affected different ethnical and cultural groups differently, with the Ultra-Orthodox Jews mostly affected by admission rates, presenting symptoms clinical course and MACE (Acute coronary syndrome, shock, cerebrovascular event or venous thromboembolism). It is conceivable that transcriptase– polymerase chain (PCR) from one of the fourth in a tract available Israel (Center disease control assay; BGI, homemade base on EU protocol, Focus Diagnostics Inc., Cypress, CA; GeneXpert® and Seegene Allplex™ 2019-nCoV Assay). Demographic data, presenting symptoms, comorbid conditions, medications and physical examination were systematically recorded. Laboratory and imaging data were collected as well. Clinical deterioration was de�ned as either death or respiratory, hemodynamic or cardiac deterioration. Respiratory deterioration was de�ned as acute new onset hypoxemia requiring mechanical ventilation, extracorporeal membrane oxygenation (ECMO), or both. Hemodynamic deterioration was de�ned as persistent hypotension requiring vasopressors to maintain mean arterial pressure ≥ 65mmHg and having serum lactate level >2mmol/L despite adequate volume resuscitation (25). Myocardial injury was de�ned as either increase in serum levels of cardiac troponin-I above the 99th percentile upper reference limit, or malignant arrhythmia (de�ned as rapid ventricular tachycardia lasting more than 30 seconds, inducing hemodynamic instability and/or ventricular �brillation). Follow-up for mortality rate at 30-day was drawn from the national health registry.
