Combining results from all nights of respiratory polygraphy, logistic mixed model regression indicated that overnight hs-cTnT increase was associated with moderate-severe sleep apnea (vs. no-mild, OR = 18.4 [1.5–224.2]), central apnea index (CAI, OR = 1.1 [1.0–1.2]), and predominantly central sleep apnea (vs. predominantly obstructive, OR = 22.9 [1.3–406.3]). This evidence concerns the gene TNNT2 and central sleep apnea syndrome.
