Abstract
Background: Pulmonary hypertension (PH) is a condition where the blood pressure increases in the pulmonary arteries, leading to reduced oxygen delivery to the body's tissues due to increased blood flow resistance. This condition can result in right ventricular hypertrophy, low cardiac output, and ischemia. In this study, the authors aim to investigate the impact of group II PH (GIIPH) on patients with congestive heart failure who were admitted with ST elevation myocardial infarction (STEMI) through a retrospective cohort study.
Methods: Using the National Inpatient Sample (NIS) database from 2017 to 2020, a retrospective cross-sectional study of adult patients with a principal diagnosis of STEMI with a secondary diagnosis with or without GIIPH according to ICD-10 (International Classification of Disease, 10th edition) codes. Several demographics, including age, race, and gender, were analyzed. The primary endpoint was mortality, while the secondary endpoints included cardiogenic shock, mechanical intubation, length of stay in days, and patient charge in dollars. Multivariate logistic regression model analysis was used to adjust for confounders, with a P value less than 0.05 considered statistically significant.
Results: The study included 26,925 patients admitted with a STEMI, 95 of whom had GIIPH. The mean age for patients with and without PH was 66.6 and 67.5 years, respectively. In the PH group, 37% were females compared to 34% in the non-PH group. The in-hospital mortality rate was higher in the PH group (31.6% vs. 9.6%, P<0.001, adjusted odds ratio (aOR) =3.33, P=0.02). The rates and adjusted odds of cardiogenic shock and mechanical ventilation were higher in the PH groups (aOR =1.15 and 2.14, respectively) but not statistically significant. Patients with PH had a longer length of stay and a higher total charge.
Conclusions: GIIPH was associated with worse clinical and economic outcomes in heart failure patients admitted with STEMI.
