Background: Numerous studies have highlighted the association between impaired lung function and ischemic heart disease, suggesting a potential link mediated by systemic inflammation. However, the extent of pulmonary functional abnormalities in elderly patients with ischemic heart disease remains inadequately explored, especially in the Indian context. Methodology: This prospective study aimed to evaluate pulmonary function among elderly patients with ischemic heart disease visiting SLN Medical College and Hospital, Koraput, Odisha, between January 2020 and March 2021. Spirometry and Doppler echocardiography were performed on 56 subjects aged 60 years and above with confirmed coronary heart disease. Data analysis employed descriptive statistics, ANOVA, t-tests, and Pearson correlation analysis. Results: The majority of participants (58.9%) were aged 60–69 years, with a mean age of 69.29 ± 5.66 years. Notable proportions of subjects exhibited impaired lung function, with restrictive-type defects predominant, particularly among older age groups. Associations were observed between impaired lung function, elevated inflammatory markers, and ischemic heart disease. Peak expiratory flow rates were below predicted values, suggesting potential mortality predictors. Discussion: The observed decline in lung function with age aligns with previous research, indicating a complex interplay between pulmonary and cardiac physiology. Systemic inflammation may contribute to impaired lung function and the development of coronary artery disease, emphasizing the need for multidisciplinary management approaches. Conclusion: Our study underscores the intricate relationship between impaired lung function, ischemic heart disease, and systemic inflammation in the elderly. Further research is warranted to elucidate underlying mechanisms and optimize management strategies, emphasizing the importance of early identification and intervention in this vulnerable population.
