[Use of cluster analysis in the bicycle ergometric loading of ischemic heart disease patients].
Possibilities of cluster analysis used in hemodynamic studies of coronary patients were examined. A total of 166 patients belonging to different functional classes and 36 normal subjects were investigated. Two cluster patterns were identified and correlated to the hemodynamic types. The determination of cluster patterns is possible in low-dose exercise.
