This decline of This decline of double amplitudedouble amplitude was not was not seen in our patients with heart disease. seen in our patients with heart disease. Furthermore Furthermore double amplitudedouble amplitude in about 50 in about 50 years old treated patients was lower than in years old treated patients was lower than in our about 50 years of age controls. This fact our about 50 years of age controls. This fact is positive because excessive is positive because excessive circadian circadian double amplitudedouble amplitude (CHAT) (CHAT) is accompanied is accompanied with an increased risk for morbidity and with an increased risk for morbidity and mortality. mortality.
