ABSTRACT
BackgroundInformation regarding the impact of cardiovascular disease (CVD) on disease progression among patients with mild coronavirus disease 2019 (COVID-19) is limited. MethodsThis study evaluated the association of underlying CVD with disease progression in patients with mild COVID-19. The primary outcome was the need to be transferred to intensive care due to disease progression. The patients were divided with and without CVD as well as stable and intensive care groups. ResultsOf 332 patients with mild COVID-19, median age was 51 years (IQR, 40-59 years), and 200 (61.2%) were female. Of 48 (14.5%) patients with CVD, 23 (47.9%) progressed to severe disease status and required intensive care. Compared with patients without CVD, patients with CVD were older, and more likely to have fatigue, chest tightness, and myalgia. The rate of requiring intensive care was significantly higher among patients with CVD than in patients without CVD (47.92% vs. 12.4%; P<0.001). In subgroup analysis, rate of requiring intensive care was also higher among patients with either hypertension or coronary heart disease than in patients without hypertension or coronary heart disease. The multivariable regression model showed CVD served as an independent risk factor for intensive care (Odd ratio [OR], 2.652 [95% CI, 1.019-6.899]) after adjustment for various cofounders. ConclusionsPatients with mild COVID-19 complicating CVD in are susceptible to develop severe disease status and requirement for intensive care. Key PointsO_ST_ABSQuestionC_ST_ABSWhat is the impact of coexisting cardiovascular diseases (CVD) on disease progression in patients with mild COVID-19? FindingsAlthough most patients with mild COVID-19 were discharged alive from hospital, approximately 47.9% patients with coexisting CVD developed severe disease status and required intensive care. CVD is an independent risk factor of intensive care among patients with mild COVID-19. MeaningCoexisting CVD is associated with unfavorable outcomes among patients with mild COVID-19. Special monitoring is required for these patients to improve their outcome.

COVID-19ABSTRACT
Objective@#To identify the characteristics including clinical features and pulmonary computed tomography (CT) features of heart failure and novel coronavirus pneumonia(COVID-19).@*Methods@#This study was a retrospective study. A total of 7 patients with Heart failure and 12 patients with COVID-19 in the Second Xiangya Hospital of Central South University between December 1, 2019 and February 15, 2020 were enrolled. The baseline clinical and imaging features of the two groups were statistically analyzed.@*Results@#There was no significant difference in age and sex between the two groups, but the incidence of epidemiological contact history, fever or respiratory symptoms in the COVID-19 group was significantly higher than that in the heart failure group (12/12 vs. 2/7, P=0.001; 12/12 vs. 4/7, P<0.001). While the proportion of cardiovascular diseases and impaired cardiac function was significantly less than that of the heart failure group(2/12 vs.7/7, P<0.001; 0/12 vs.7/7, P<0.001). For imaging features, both groups had ground-glass opacity and thickening of interlobular septum, but the ratio of central and gradient distribution was higher in patients with heart failure than that in patients with COVID-19 (4/7 vs. 1/12, P=0.04). In heart failure group, the ratio of the expansion of small pulmonary veins was also higher (3/7 vs. 0, P=0.013), and the lung lesions can be significantly improved after effective anti-heart failure treatment. Besides, there are more disease with rounded morphology in COVID-19 (9/12 vs. 2/7, P=0.048) .@*Conclusions@#More patients with COVID-19 have epidemiological history and fever or respiratory symptoms. There are significant differences in chest CT features, such as enlargement of pulmonary veins, lesions distribution and morphology between heart failure and COVID-19.
ABSTRACT
OBJECTIVES To compare chest CT findings in heart failure with those of Corona Virus Disease 2019 (COVID-19) pneumonia. BACKGROUND During epidemic period, chest computed tomography (CT) has been highly recommended for screening patients with suspected COVID-19. However, the comparison of CT imaging between heart failure and COVID-19 pneumonia has not been fully elucidated. METHODS Patients with heart failure (n=12), COVID-19 pneumonia (n=12) and one patient with both diseases were retrospectively enrolled. Clinical information and imaging of chest CT were collected and analyzed. RESULTS There was no difference of ground glass opacity (GGO), consolidation, crazy paving pattern, lobes affected and septal thickening between heart failure and COVID-19 pneumonia. However, less rounded morphology (8.3% vs. 67%, p=0.003), more peribronchovascular thickening (75% vs. 33%, p=0.041) and fissural thickening (33% vs. 0%, p=0.028), less peripheral distribution (33% vs. 92%, p=0.003) were found in heart failure group than that in COVID-19 group. Importantly, there were also more patients with upper pulmonary vein enlargement (75% vs. 8.3%, p=0.001), subpleural effusion and cardiac enlargement in heart failure group than that in COVID-19 group (50% vs. 0%, p=0.005, separately). Besides, more fibrous lesions were found in COVID-19 group although there was no statistical difference (25% vs. 0%, P=0.064) CONCLUSIONS Although there are some overlaps of CT imaging between heart failure and COVID-19, CT is still a useful tool in differentiating COVID-19 pneumonia.
