Arterial Hypertension and Diabetes Mellitus in COVID-19 Patients: What Is Known by Gender Differences?

BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has infected >160 million people around the world. Hypertension (HT), chronic heart disease (CHD), and diabetes mellitus (DM) increase susceptibility to SARS-CoV-2 infection. AIMS: We designed this retrospective study to assess the gender differences in hypertensive diabetic SARS-CoV-2 patients. We reported data, by gender differences, on the inflammatory status, on the hospital stays, intensive care unit (ICU) admission, Rx and CT report, and therapy. METHODS: We enrolled 1014 patients with confirmed COVID-19 admitted into different Hospitals of Campania from 26 March to 30 June, 2020. All patients were allocated into two groups: diabetic-hypertensive group (DM-HT group) that includes 556 patients affected by diabetes mellitus and arterial hypertension and the non-diabetic- non-hypertensive group (non-DM, non-HT group) comprising 458 patients. The clinical outcomes (i.e., discharges, mortality, length of stay, therapy, and admission to intensive care) were monitored up to June 30, 2020. RESULTS: We described, in the DM-HT group, higher proportion of cardiopathy ischemic (CHD) (47.5% vs. 14.8%, respectively; p < 0.0001) and lung diseases in females compared to male subjects (34.8% vs. 18.5%, respectively; p < 0.0001). In male subjects, we observed higher proportion of kidney diseases (CKD) (11% vs. 0.01%, respectively; p < 0.0001), a higher hospital stay compared to female subjects (22 days vs. 17 days, respectively, p < 0.0001), a higher admission in ICU (66.9% vs. 12.8%, respectively, p < 0.0001), and higher death rate (17.3% vs. 10.7%, respectively, p < 0.0001). CONCLUSION: These data confirm that male subjects, compared to female subjects, have a higher hospital stay, a higher admission to ICU, and higher death rate.

Left Atrial Longitudinal Speckle Tracking Echocardiography in Healthy Aging Heart.

BACKGROUND: Left atrial volume (LAV) and function are connected to the left ventricular (LV) haemodynamic patterns. To define the changes of LAV and functions to counterbalance age-related LV diastolic impairment, this study was undertaken. METHODS: 2D-Left Atrial Speckle Tracking Echocardiography (2D-LASTE) was used to define both LAV and functions in an aged healthy population (group II) respect to adult healthy controls (group I). RESULTS: Results showed an increasing of left atrial volume indices (LAVI) (maximum, minimum, pre-a) in old subjects in comparison with those obtained in adult healthy controls. On the contrary, LAVI passive emptying unchanged and LAVI passive fraction reduced with advanced age. Finally, LAVI active emptying increased with advancing age to compensate the age-dependent left ventricular diastolic dysfunction. The values of global systolic strain (S); systolic strain rate (SrS); early diastolic strain rate (SrE), and late diastolic strain rate (SrA) were also calculated. With reference to the function, our study confirmed that LA conduit function deteriorates with age while booster pump increases respect to adult controls and reservoir phase is maintained. CONCLUSIONS: The echocardiographic findings obtained with conventional and tissue Doppler confirmed the connection between LA functions and volumes and age-related LV dysfunction. Conclusively, 2D-LASTE appears to be a reliable tool to evaluate the role of LA to compensate the derangement of left ventricle happening with ageing.

Three-Dimensional Trans-Thoracic Echocardiography of Esophageal Achalasia: Description of a Case.

Esophageal achalasia is a motility disorder characterized by impaired relaxation of the lower esophageal sphincter and dilatation of the distal two-thirds of the esophagus. This condition may be a non-frequent reason of extrinsic compression of left atrium. In turn, this can be a cause of some hemodynamic changes such as chest discomfort, dyspnea or reduced exercise tolerance, systemic hypotension and tachycardia. We describe a case of a patient with esophagus achalasia compressing the left atrium and inducing hemodynamic compromise. The diagnostic methods, as chest X-ray, computed tomography (CT), manometry, and 2D-Trans-Thoracic Echocardiography (TTE) demonstrated the esophagus dilation, the impaired relaxation of the lower esophageal sphincter, and its compression on the left atrium. Three-D Trans-Thoracic Echocardiography (3D-TTE) was firstly performed also. This last examination pointed out better than 2D-TTE the extrinsic compression of the left atrium due to the esophagus dilatation. Therefore, 3D-TTE is a true improvement for the echocardiographic diagnosis of the left atrial compression induced by esophageal achalasia.

Left Atrial Volume Index as Indicator of Left Ventricular Diastolic Dysfunction: Comparation between Left Atrial Volume Index and Tissue Myocardial Performance Index.

BACKGROUND: To point out a possible correlation between left atrial volume index (LAVI) and left ventricular (LV) diastolic time interval to better define LV diastolic dysfunction, this study was performed. METHODS: In 62 hypertensive-hypertrophic patients without LV systolic dysfunction, LV volumes, myocardial mass index, ejection fraction% (EF%) and LAVI were measured by two-dimensional echocardiography. Instead, tissue Doppler echocardiography (TDE) was used to measure myocardial performance index (MPI) and its systo-diastolic time intervals, such as: iso-volumetric contraction time (IVCT); iso-volumetric relaxation time (IVRT); ejection time. LAVI, TDE-MPI and time intervals where also measured in 15 healthy controls, to obtain the reference values. RESULTS: Results shown a significant increase of LV volumes in hypertensives in comparison to the control group (p < 0.05). LV mass index also augmented (p < 0.001). Instead, EF% not significantly changed in hypertrophic patients in comparison with healthy controls. LAVI raised in hypertensives wih left ventricular hypertrophy, whereas IVCT resulted within the normal limits. On the contrary, IVRT significantly raised. Accordingly, MPI resulted higher in controls. CONCLUSION: LAVI, MPI and its time intervals appear as reliable tools to non-invasively individualize LV diastolic dysfunction in systemic hypertension, in absence of mitral valve disease.
