Inclusion criteria

Inclusion criteria: The study subjects will be recruited from the patients who will be admitted to the cardiovascular department in Saiseikai Futsukaichi hospital to undergo the cardiac catheterization or CMR measurement.

Exclusion criteria

Exclusion criteria: The patients who have shunt for hemodialysis or who cannot perform or are not suitable for breath-holding like patients with dementia or acute myocardial infarction will be excluded.

Design outcomes

Primary

Measure	Time frame
The relationship will be analyzed between CI obtained by cardiac magnetic resonance (CMR) or cardiac catheterization and LFCT that is measured during the patients awake or measured from the data of overnight polysomnography. The accuracy of the oxygen saturation (SpO2) obtained from our co-developed system will be confirmed by comparison with those obtained from the oxygen values from the conventional measurement of arterial oxygen partial pressure during the catheterization procedure or SpO2 from a commercially available SPO2 monitor device.	—
