COVID-19 mainly causes pulmonary manifestation; nonetheless, its systemic inflammatory response involves multiple organs, including the heart. We aimed to evaluate the prevalence, predictors, and outcomes of myocardial injury in hospitalized patients with SARS-CoV-2 infection. Methods and Results: We performed an observational retrospective analysis on patients hospitalized with COVID-19 in a moderate-sized community hospital system. Myocardial injury was defined as highly sensitive troponin T levels in the 99th percentile above the normal upper limit for the respective biological sex. Multivariable logistic regression models were fitted to assess the association between the myocardial-injury and the no-myocardial-injury groups for primary and secondary outcomes. A total of 1632 (49.3% male, 41.7% aged 60–79 years) patients with COVID-19 were included, out of which 312 (19.1%) had a myocardial injury. Patients with myocardial injury were older (36.9% > 80 years) and had higher cardiovascular-related comorbidities than those without. The prevalence of cardiovascular risk factors (78.5% vs. 52.0%) and cardiovascular diseases (78.2% vs. 56.1%) was much higher in the myocardial-injury group. Older age (50–64 years vs. <49 years; OR, 3.67 [1.99–6.74]), Angiotensin Receptor Blockers (ARBs) (OR, 1.44 [1.01–2.05]), Beta-blockers (OR, 2.37 [1.80–3.13]), and cardiovascular comorbidities (OR, 1.49 [1.09–2.05]) were strong predictors of cardiac injury after multivariable adjustment. Myocardial injury was strongly associated with ICU admission (adjusted OR, 1.68 [1.29–2.19]) and longer length of hospital stay (median days, 5 (3, 9) vs. 4 (2, 7)). The results do not show a significant difference in the use of mechanical ventilation (OR, 1.29 [0.87–1.89]) or in-hospital mortality (OR, 1.37 [0.98–1.91]) with respect to myocardial injury. Conclusion: This multicenter retrospective study of nearly 1600 patients revealed the following findings: Myocardial injury was observed in 1 out of 5 patients hospitalized with COVID-19 but was more often clinically insignificant. Patients of age > 65 had very high odds of having elevated troponin levels after adjusting for sex and other illnesses. Pre-existing cardiac diseases and risk factors were robust predictors of cardiac injury after adjusting for age and sex. In the adjusted model, myocardial injury was not associated with the requirement of mechanical ventilation or change in in-hospital mortality.

Discussion: CL should be considered as a differential in patients with multiple aggregated mucosal lesions that appear as polyps on endoscopy. Speculation on etiology has ranged from developmental (failure to establish connections to lymphatic drainage sites), or seen secondarily after trauma, prior surgeries, radiation, lymphatic obstruction possibly secondary to adjacent mass lesion, or previous inflammatory processes. Free intraperitoneal air may suggest impending clinical decline in such patients. Surgical resection is the treatment of choice in symptomatic patients.[1990] Figure 1.
