Review of Echocardiographic Findings in Patients with Obstructive Sleep Apnea

Table 5

Left ventricular myocardial performance index in relationship with OSA severity.

Echocardiographic variables		AHI <5 events·h^−1	Mild OSA	Moderate OSA	Severe OSA
LV-MPI	Dursunoglu et al. [9]		0.50 ± 0.09	0.60 ± 0.10 ^‡	0.64 ± 0.14^‡	0.01
	Altekin et al. [14]	0.46 ± 0.08	0.48 ± 0.08	0.55 ± 0.06^†	0.6 ± 0.13^†,‡	<0.05
	Vitarelli et al. [24]	0.39 ± 0.08	0.43 ± 0.07		0.58 ± 0.09^†	0.039

LV-MPI: left ventricular myocardial performance index; AHI: apnea-hypopnea index; OSA: obstructive sleep apnea. ^†Significantly different from AHI <5 events·h⁻¹; ^‡significantly different from mild OSA.
