Pulmonary hypertension in schistosomiasis mansoni.
To evaluate cardiopulmonary involvement in schistosomiasis mansoni, 246 patients from an endemic area of Brazil were examined; 152 had been previously treated for schistosomiasis. Based on stool examination and/or abdominal ultrasonography, the patients were divided into those with schistosomiasis (69%) and those in whom the disease was not present (31%). M mode measurements were similar in the 2 groups. Pulmonary pressure was measured by Doppler echocardiography; 25% of the subjects had pulmonary hypertension. Those with pulmonary hypertension had a higher prevalence of schistosomiasis (80%) than those without (64%; P = 0.03). No case of cor pulmonale was diagnosed by electrocardiography or Doppler echocardiography. The prevalence of pulmonary hypertension correlated neither with periportal fibrosis nor with prior treatment for schistosomiasis.
