Abstract
Body weight may be increased or decreased in subjects diagnosed with pulmonary arterial hypertension (PAH) or chronic thromboembolic hypertension (CTEPH). This alteration is related to the prognosis of the disease.
Objective: To identify the prevalence of low or high weight syndrome in subjects with pulmonary hypertension (HP) from 7 hospital centers of the Colombian Pulmonary Hypertension Network.
Methods: Sociodemographic and clinical patient study with diagnosis of PAH or CTEPH. Weight and height were included for body mass index calculation (BMI, kg/m2) at diagnosis. Values were categorized according to WHO criteria[1]. Potential association with demographic, functional and outcome variables was evaluated.
Results: Weight and height data were available in 371 subjects (47.4%). Weight was affected in 49.1% of patients. Underweight prevalence at diagnosis was 6.5%, obesity 10.8% and overweight 31.8% (Table 1). Underweight subjects were younger (median, 26.3 vs. 41.4-51.1-51.6 years in the other groups), but showed higher PVR (24 uW vs. 11.5 Wood in the others) (Table 2).
Conclusion: 49% of HP patients show abnormal weight at the point of diagnosis. Underweight is 2.9 times more frequent than in general population (7% of the total), in association with younger age and greater severity (PVR) of the disease.
[1] Underweight (BMI>18.5), Normal Weight (BMI 18.5-24.99), Overweight (BMI 25-29.9) or Obesity (BMI>30).
