Abstract
INTRODUCTION:
Pulmonary arterial hypertension (PAH) is a serious pulmonary circulation
disease caused by several etiologies, including schistosomiasis. The present
study retrospectively evaluated the clinical and hemodynamic characteristics
of patients with schistosomal PAH (PAH-Sch) compared to those of non-Sch PAH
patients (non-Sch PAH).
METHODS:
Patients treated at the Pronto-Socorro Cardiológico de Pernambuco and
diagnosed by right cardiac catheterization were divided into PAH-Sch and
non-Sch PAH groups. Their socio-demographic and clinical characteristics,
N-terminal-pro B-type natriuretic peptide (NT-proBNP), and echocardiography
and hemodynamic parameters were retrospectively reviewed.
RESULTS:
Among the included 98 patients (mean age, 45 ± 14 years; 68 women [69.4%]),
we found 56 PAH-Sch and 42 non-Sch PAH. The age distribution was
heterogeneous in the PAH-Sch group, with patients predominantly ranging from
50-59 (p <0.004). Dyspnea was the most common symptom, reported by 92
patients (93.8%), and commonly present for over two years prior to
diagnosis. Clinical symptoms were similar in both groups, with no
differences in functional class, pulmonary artery systolic pressure (p =
0.102), 6-minute walk test score (p = 0.234), NT-proBNP serum levels (p =
0.081), or hemodynamic parameters.
CONCLUSIONS:
Patients with PAH-Sch present clinical, laboratory, and hemodynamic profiles
similar to those with PAH resulting from other etiologies of poor prognosis.
PAH is an important manifestation of schistosomiasis in endemic regions that
is often diagnosed late.
