Chronomic cardiovascular surveillance serves to recognise and treat any risk elevation as well asovert disease, and to ascertain whether treatment is effective and, if so, for how long treatmenteffects lasts, be it for lowering an increased risk and/or in surveilling the success or failure oftreatment. A treatment-associated increase in circadian amplitude of blood pressure (BP) mayinduce iatrogenic overswinging, also dubbed CHAT (circadian hyper-amplitude-tension), in somepatients, thereby increasing cardiovascular disease risk unknowingly to care provider and receiver.
