CS induces oxidative stress and endothelial dysfunction, which has a profound impact on cardiac structure and function. While the protective effects of estrogen, particularly 17β-estradiol (E2), on cardiovascular health are well-documented in premenopausal women, the interaction between estrogen and CS remains poorly understood. The aim of this study is to investigate the impact of chronic cigarette smoking on cardiac health in relation to ethinylestradiol (EE) oral contraceptive (OC) usage in premenopausal females. Female mice were exposed to chronic cigarette smoke and co-administered EE. Cardiac structural and functional parameters were assessed alongside inflammatory markers, oxidative stress indicators, and histological changes. Results revealed that the combination of EE and CS led to adverse cardiac remodeling characterized by increased left ventricular end-diastolic volume and elevated left ventricular mass. In addition, an inflammatory state was evident, marked by increased expression of IL-4, IL-1β, IL-13, IL-10, and PARP-1, as well as increased interstitial collagen deposition. These findings suggest a progression towards adverse cardiac remodeling resembling dilated cardiomyopathy. Furthermore, our observations highlight the complexity of the inflammatory response triggered by smoking, potentially exacerbated by estrogen supplementation.
