Right atrial strain is independently associated with SPAP level. RA strain lower than 42.5% can predict a SPAP > 37 mm Hg with high sensitivity and specificity.

Aims Isometric indexation of cardiac structures fails in patients with overweight. The aim of the study was to evaluate the LA indexed volume (LAVOL), left ventricular end‐diastolic diameter (LVEDD), left ventricular mass index (LVMI), and the aortic sinus diameter (AOSD) in healthy subjects with normal and high BMI and find the allometric correction exponent. Methods Four hundred and thirty patients without cardiac pathology were analyzed. Patients were divided into groups: Group I BMI < 24.9 187 patients, Group II BMI 25‐29.9 154 patients, Group III BMI 30‐34.9 63 patients, and Group IV 35‐39.9 26 patients. A Doppler echocardiogram was performed. The parameters indexed were compared between groups. When allometric growth was verified, the allometric coefficient was calculated. Results Male sex 242 p (56%), mean age: 44.87 ± 13.10 years, better correlation: LAVOL, LV mass, and AOSD with body surface area (BSA) (LAVOL R: .74, R2 .55, LV mass R: .73, R2: 0.53, AOSD R: .57, R2: .35), LVEDD with high (R: .63, R2: .39) were observed. A significant increase was observed in LAVOL and LVMI in the groups with increased BMI. We observed a decrease in the indexed AOSD and a marginal difference between groups in LVEDD. The allometric correction exponent calculated was as follows: LAVOL: 0.96 and for LVMI: 0.97. Conclusions Allometric correction is superior to isometric indexation to assess LAVOL and LVMI in obese and overweight patients. Allometric correction would allow differentiating deviations from VOLAI and IMVI attributable to obesity from those attributable to an associated pathology.

Objectives: The aim of this study was to assess differences in echocardiographic findings between a normal adult and a post Covid-19 population. Background: Coronavirus disease (Covid-19) is known to produce a systemic inflammatory syndrome, with pulmonary and cardiac involvement. However, the cardiovascular impact in patients with mild clinical forms of the disease is uncertain. There is small evidence supporting the finding of global ventricular longitudinal strain (GLS) alterations in these patients. Methods: One hundred and five consecutive patients admitted to an ambulatory care center, underwent a conventional transthoracic echocardiographic (TTE) study with acquisition of GLS. Patients were included if they underwent a positive diagnostic reverse transcriptase polymerase chain reaction (PCR) test, having no relevant preexisting conditions, with exception of obesity. Demographic and clinical data were prospectively obtained. For this purpose, we considered a normal cut off point of -17,09%, based on previous studies. Echocardiographic findings were compared with those of 67 healthy individuals. Results: Out of 172 patients, 105 correspond to Covid-19 group, and 67 to healthy individuals. There were no significant differences in GLS regarding age, left ventricular mass index (LVMI) and E/e’ ratio. The multivariate analysis showed that the percentage of patients with pathological GLS values was significantly higher within the Covid-19 and male groups (OR 6.02 IC 1.88-22.57; p 0.004 and OR 3.17 IC 1.03-10.50; p 0.05, respectively). Conclusion: These data support that Covid-19 infection could affect ventricular GLS and encourage the use of conventional TTE with GLS measurements in patients with non-significant forms of the disease.
