Key result
Among patients with acute myocardial infarction, concomitant obstructive sleep apnea was associated with exacerbated cardiac damage, including higher troponin T (2298 vs. 356 pg/mL).
Why the study?
Given the suggested association between AMI and OSA and their shared risk factor of obesity, this study aimed to investigate the involvement of adipokines in AMI patients with and without OSA.
Does the presence of obstructive sleep apnea increase inflammatory markers and cardiac damage in patients with acute myocardial infarction?

Does the presence of obstructive sleep apnea increase inflammatory markers and cardiac damage in patients with acute myocardial infarction?
Obstructive sleep apnea is associated with greater cardiac damage and elevated inflammatory markers in patients with acute myocardial infarction.
An association has been suggested between acute myocardial infarction (AMI) and obstructive sleep apnea (OSA). Considering the role of adipose-tissue-derived inflammatory mediators (adipokines) and the shared risk factor of obesity in OSA and AMI, this study aimed to investigate the involvement of adipokines in AMI patients with and without OSA. Serum levels of adipokines and inflammatory mediators were quantified, and home respiratory polygraphy was conducted. A total of 30 AMI patients and 25 controls were included. Patients with AMI exhibited elevated levels of resistin (7.4 vs. 3.7 ng/mL), interleukin-6 (8.8 vs. 1.3 pg/mL), and endothelin-1 (3.31 vs. 1.8 pg/mL). Remarkably, AMI patients with concomitant OSA exhibited higher levels of resistin (7.1 vs. 3.7 ng/mL), interleukin-6 (8.9 vs. 1.3 pg/mL), endothelin-1 (3.2 vs. 1.8 pg/mL), creatin kinase (1430 vs. 377 U/L), creatine kinase-MB (64.6 vs. 9.7 ng/mL), and troponin T (2298 vs. 356 pg/mL) than their non-OSA counterparts. Leptin showed a correlation with OSA severity markers. OSA was associated with greater cardiac damage in AMI patients. Our findings underscore that adipokines alone are not sufficient to discriminate the risk of AMI in the presence of OSA. Further research is necessary to determine the potential mechanisms contributing to exacerbated cardiac damage in patients with both conditions.

Vega-Jasso et al. (2023) conducted a case-control in Acute Myocardial Infarction and Obstructive Sleep Apnea (n=55). Obstructive sleep apnea vs. No obstructive sleep apnea was evaluated on Serum levels of adipokines, inflammatory mediators, and cardiac damage markers. Among patients with acute myocardial infarction, concomitant obstructive sleep apnea was associated with exacerbated cardiac damage, including higher troponin T (2298 vs. 356 pg/mL).
