The association between orthostatic increase in pulse pressure and ischemic heart disease.
The clinical meaning of changes in PP with posture remains unclear. We performed treadmill exercise testing on 144 subjects to diagnose ischemic heart disease, and measured the PPs in the supine and standing positions. The differences in the two PPs ranged between -35 and 45 mmHg. Eleven subjects were diagnosed with significant coronary ischemia. The differences in the PPs were significantly increased, and PP in the standing position was significantly elevated in these subjects. A large difference in the PPs in the standing and supine positions was associated with significant coronary ischemia, independent of significant covariables.
