Creatine kinase (CK/CK‐MB) testing is an essential laboratory test approaching a patient with chest or epigastric pain. We report a 38‐year‐old man with acute pancreatitis and elevated CK/CK‐MB level without myocardial involvement. Acute pancreatitis may be considered as a false‐positive cause of CK/CK‐MB test in patients presenting with chest pain.

Background Cardiac hydatidosis is a rare disease and the subepicardial region of the left ventricular is commonly affected. However, papillary muscle concomitant with brain involvement has not been previously reported. Case We report a 44 years old man who complained of headache along with no cardiac symptoms. The patient was diagnosed with cerebral hydatid cyst. Through preoperative cardiac consultant, transthoracic echocardiography revealed cardiac hydatid cyst confined to the anterolateral papillary muscle. Medical treatment was started promptly and successful surgical excision of all cysts was performed. The patient had an uneventful recovery and follow up at 3 months. Conclusion Early diagnosis of cardiac HC by echocardiography is recommended in all patients with hydatid disease, regardless of HC location.

Background: COVID-19 is associated with a high rate of thromboembolic events in hospitalized patients, but it is unclear whether this risk remains high after discharge. This study aimed to evaluate the association of underlying factors with post-discharge thrombolytic events in COVID-19 patients and the association of thrombolytic events with subsequent mortality and ischemic heart disease. Methods: In this study, eligible patients with COVID-19 who were admitted to the respiratory ward of Loghman Hakim Hospital, Tehran, Iran, followed up for about 3 months after discharge to record any thromboembolic events. Patients who reported postdischarge thromboembolic events were confirmed based on their diagnostic tests. The Chi-square test was used to evaluate the association between thromboembolic events and qualitative parameters, and an independent t-test was used to evaluate their association with quantitative parameters. Logistic regression analysis was performed to assess the association between independent variables and the composite outcome. Results: Thromboembolic events were diagnosed in 35 patients (5.04%), including Myocardial Infarction (MI) in 17 patients (2.44%), venous thromboembolism in 10 patients (1.44%), and ischemic stroke in 8 patients (1.15%). None of the 26 patients who received thromboprophylaxis had thromboembolic events. During follow-up, 22 patients (3.17%) died, of whom, 10 patients (43.47%) had thromboembolic events. Thromboembolic events were not associated with sedentary life and oxygen (O2) dependency after discharge (P value of 0.40 and 0.098, respectively). Regression analyses showed that thromboembolic events were significantly associated with ischemic heart disease and mortality (P=0.007 and P<0.001, respectively). Conclusion: Our findings support a high rate of post-hospitalization thromboembolic events in COVID-19 patients; however, it needs more large-scale trials.
