Introduction:

The disorders secondary to chronic kidney disease (CKD), such as systemic inflammation, anemia, and fluid overload are an important substrate for the development of pulmonary arterial hypertension.

Objective:

To assess the relationship between pulmonary artery systolic pressure (PASP) on echocardiogram and the duration and type of renal replacement therapy (RRT) in patients with CKD.

Method:

A retrospective observational study at Hospital de Especialidades del Centro Médico Nacional La Raza. The analysis was performed using measures of central tendency and dispersion. Chi square was used to compare percentages through the SPSS 25 statistical program.

Results:

A total of 141 patients with CKD on RRT with peritoneal dialysis or hemodialysis were included. They were classified according to PASP as normal (30 patients, 21.28%), mild (43 patients, 30.5%), moderate (16 patients, 12%) and severe (52 patients, 36.88%). The duration of RRT is related to a higher PASP, with 3.53 years for a normal PASP, 5.51 years for mild PASP, 6.00 years for moderate PASP, and 6.38 for those with severe PASP. Severe PASP occurred in 13 of 56 patients on peritoneal dialysis and 39 of 85 patients on hemodialysis (p = 0.034).

Conclusions:

This study found a relationship between PASP and the duration and type of renal replacement in patients with CKD.
