Abstract

Background: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. Most of these deaths are related to cardiovascular disease. This is due to systemic inflammation that causes increased vascular stiffness and hypertension. These comorbidities lead to poor quality of life, low exercise tolerance, and an increased risk of hospitalization. This study aims to report the proportion of hypertension among stable COPD patients in the Indonesian population.Methods: This cross-sectional study was conducted at the National Respiratory Center Persahabatan Hospital between February and March 2023. Stable COPD patients admitted to the Asthma and COPD Polyclinic who met the criteria were enrolled. Clinical information, vital signs, spirometry results, and DLCO measurements were collected.Results: There were 84 subjects participating in this study. The result of this study shows a 60.7% proportion of hypertension in stable COPD patients. Hypertension has a significant correlation with pulmonary functional values (P=0.021), severity degree of clinical COPD (P=0.004), Brinkman index (P=0.008), and age (P=0.0001). However, hypertension association with COPD duration (P=0.505) and DLCO (P=0.122) were not significant.Conclusion: The hypertension proportion in stable COPD Indonesian patients is 60.7%. Hypertension shows a significant association with pulmonary function values, severity degree of clinical COPD, Brinkman index, and age.

Abstract

Flight crews frequently experience intermittent hypobaric hypoxia (IHH), which may trigger oxidative stress and vascular remodeling in the pulmonary arteries. This study investigated the effects of IHH exposure on oxidative stress markers, tunica media thickness, and the expression of LR11 and HIF-1α proteins in rat pulmonary arteries using five groups of healthy male Sprague–Dawley rats (n = 5 per group). Twenty-five male Sprague–Dawley rats were divided into five groups: a control group and four treatment groups exposed to simulated altitudes of 25,000 ft (7,620 m) for 5 minutes per day over 1, 3, 7, or 14 days. Levels of HIF-1α and LR11 were measured using ELISA, oxidative stress markers such as γ-glutamyl-cysteinyl-glycine (GSH) and malondialdehyde (MDA) were analyzed spectrophotometrically, and tunica media thickness was assessed histologically. HIF-1α levels peaked after acute hypoxia exposure and declined with prolonged exposure, whereas LR11 levels progressively increased, peaking in the 14-day group. MDA levels, reflecting oxidative stress, were highest after 3 days of exposure, while GSH levels decreased in all hypoxia groups compared with the control. Histological analysis showed the greatest tunica media thickness in the 3-day exposure group, followed by gradual reductions. Although no statistically significant correlations were found between protein levels and tunica media thickness, similar directional trends suggest biologically relevant associations. Intermittent hypobaric hypoxia (IHH) induces dynamic changes in oxidative stress and vascular remodeling in rat pulmonary arteries. Acute hypoxia increases HIF-1α expression and oxidative stress, whereas repeated exposures appear to trigger compensatory adaptations, including LR11 upregulation and tunica media remodeling. These findings demonstrate measurable molecular and structural alterations underlying pulmonary vascular responses to repeated high-altitude exposure.
