title: [Application of pneumothermometric index for respiratory thermoregulation assessment in patients with ischemic heart disease].
abstract: We enrolled 153 patients with Ischemic Heart Disease admitted to general hospital: 33--with aterosclerotic cardiosclerosis, 70--with acute myocardial infarction (AMI), 17--with postinfarctial cardiosclerosis, 33--with unstable angina. 30 control subjects (middle aged men and women) were recruited. Exhaled breath temperature (Te), ambient temperature (Tam) and axillaris temperature (Tax) were measured. The predicted expired air temperature (prTe) and three pneumothermometric indexes were calculated: index ThetaEAT-(Te-Tam)/(prTe-Tam); index DeltaEAT-(Tax-Te)/(Tax-prTe); index lamdaEAT-(Te-predTe)/(Te-predTe). Index DeltaEAT is the most effective index for revealing disorders of respiratory heat exchange in myocardial infarction. Index lamdaEAT is the most effective pneumothermic one for revealing disorders of respiratory heat exchange in aterosclerotic cardiosclerosis.
