ABSTRACT
Obesity and Eisenmenger's syndrome are entities widely studied. However, its association is unusual and has not been reported. A wide range of gas exchange abnormalities have been describe in both groups. In the severe obese patients this abnormalities are attributed to a ventilation/perfusion mismatch and to an increase pulmonary venous-arterial shunt, that correlates with the lung volume. In severe obese patients with the Eisenmenger's syndrome, this correlation is unknown. METHODS:
We studied 28 obese subjects paired by body mass index > 30 kg/m2. Assigned to two groups, obese with Eisenmenger's syndrome and obese without the syndrome. Clinical variables, respiratory function, echocardiography and gas exchange pre and post-deep breathing maneuver were obtained. Statisticalanalysis:
The variables are expressed with mean+/-standard deviation. Student t test for paired groups and Pearson correlation coefficient were gathered for the differences and associations between groups. A p-value <0.05 was considered significant.RESULT:
Age was 48.57 +/- 10.32 vs 60.86 +/- 10.47 y.o. respectively, p < 0.004. Systolic pulmonary arterial pressure 104.36 +/- 37 vs 50.1 +/- 12 mm Hg, p < 0.001. The arterial oxygen pressure at rest and during the deep breathing maneuver in each group was 51.64 +/- 6.38 vs 57.14 +/- 11, p < 0.188 and 56.29 +/- 11.15 vs 72 +/- 11.83, p < 0.001; venous-arterial shunt 12.79 +/- 3.66 vs 13.07 +/- 4.84, p < 0.767 and 9.21 +/- 3.77 vs 6.5 +/- 2.28, p < 0.001; alveolar arterial oxygen difference 271.14 +/- 79.92 vs 243.79 +/- 92.07, p < 0.001, respectively.Conclusion:
Obese subjects with Eisenmenger's syndrome, did not have significant improvement of gas exchange with the deep breathing maneuver.
