According to preliminary research, COVID-19 is linked to high-rate cardiac arrhythmias. COVID-19 patients who have underlying cardiovascular problems have a higher death rate. Acute coronary syndrome, venous thromboembolism, myocardial injury, and arrhythmias can all be brought on by COVID-19. Among other things. Cardiac biomarkers are essential for the quick and accurate diagnosis, treatment, and prognosis of acute coronary syndrome. It is essential to receive a diagnosis during the "golden period" inorder to start therapy right away and maybe reverse cardiac damage. In this study, the risk of cardiac arrest, and arrhythmias such Atrial- Fibrillation (AF) and Brady arrhythmias was evaluated, as well as to see if covid-19 might affect cardiac patients' blood parameters. It will also assist us in determining the degree of cardiac arrest and arrhythmias and how cardiac markers will react following a CVS. We look at people who have been diagnosed with CVS and been a COVID-19 hospital admission during the months of November 2021 and March 2022, data was gathered at the Allama Social Security Hospital in Gujranwala, Pakistan. The research took around 5 months to complete. In this study, 110 patients between the ages of 30 and 60 were recruited after giving their informed permission. The study participants proceeded to the hospital, where trained staff members who were in charge of gathering specimens and making sure that all vials were appropriately labelled collected Covid-19 samples. Covid-19 samples are collected using a nasopharyngeal swab or an or pharyngeal swab. As indicated in table, our study included 110 Cardiac and COVID-19 patients varying in age from thirty to sixty, with 51 patients being male (46.4%) and 59 being female (53.6%). The age groups of patients show us the statistics of Cardiac markers (CKMB, SGOT, CPK, CRP) and CBC (HB, WBC, Platelets and RBCS). The (Graph 3,4,5 and 6) shows us the relationship of Cardiac and Covid-19 patients with Cardiac Markers. The (Graph 7, 8, 9 and 10) shows us the relationship of Cardiac and Covid-19 patients with CBC Blood parameters. The cardiac markers are disrupted as a result of cardiac arrest, and the patients are diagnosed with cardiac arrhythmia. If a patient is already Covid-19 positive, changes in blood parameters will occur. As a consequence, cardiac indicators will be affected more, making the situation worse. As a result, heart rhythms will be disrupted, and blood circulation throughout the body will be disrupted. If the problem is not handled quickly, the patient will automatically get seriously ill. Dysrhythmias and cardiovascular arrests are going to be coming from a systemic illness, and COVID-19 will alter blood parameters, potentially affecting heart circulation in patients with severe cardiac disease.
