What is Association of right ventricular dysfunction and Cheyne–Stokes respiration in patients with chronic heart failure about?
## Summary Cheyne–Stokes respiration (CSR) is present in up to 40% of patients with congestive heart failure (CHF) and is an independent risk factor for increased overall mortality. We examined whether CSR is associated with right ventricular (RV) dysfunction in CHF patients. Parameters of RV function were assessed by two‐dimensional echocardiography and tissue velocity imaging in 42 patients (aged 23–75 years) with a left ventricular (LV) ejection fraction below 40%. Respiratory polygraphy revealed CSR with an central apnea–hypopnea index (CAHI) >10 h^−1^ in 13 of the 42 patients (31%). Demographic characteristics did not differ among the patient groups. The velocity of the tricuspid annular systolic motion (TASM), a parameter reflecting systolic RV function, was significantly reduced in CHF patients with CSR (10.5 ± 2.3 cm s^−1^) compared with those without CSR (15.0 ± 5.1 cm s^−1^, __P__ = 0.004), and was inversely associated with the CAHI (__y__ = 15.2–0.2__x__; __r__ = 0.46, __P__ = 0.003). The RV dimensions were significantly increased and the fractional RV area changes significantly reduced in CHF patients with CSR (33 ± 17 versus 48 ± 20%; __P__ = 0.04). Doppler parameters
