Relationship between the degree of pulmonary hypertension and postoperative mortality in adult cardiac surgery


Objective: This study aimed to investigate the association between the intensity of pulmonary hypertension and the probability of mortality following cardiac surgery in adults.

Design: This study employed an analytical observational methodology, utilizing a retrospective approach and a cross-sectional design.

Setting: The medical record of the Integrated Heart Center Intensive Care Unit (ICU) of Dr. Wahidin Sudirohusodo Central General Hospital Makassar, South Sulawesi. The study was conducted on 1-15 July 2023.

Patient and participants: Adults with a diagnosis of pulmonary hypertension who required therapy in the ICU following heart surgery.

Interventions: None.

Measurement and results: The data collected included demographic data (age, gender, diagnosis), heart disease data (degree of pulmonary hypertension based on echocardiography examination), and mortality data (data on survivors and non-survivors after surgery and causes of mortality after surgery). The degree of pulmonary hypertension was divided into low-, intermediate-, and high-probability. Significant differences were found between the three groups (p<0.05) when comparing the incidence of mortality.

Conclusions: A direct relationship exists between the occurrence of pulmonary hypertension and the rate of death after heart surgery among patients at the Integrated Heart Centre ICU of Dr. Wahidin Sudirohusodo General Hospital.
