1 2 CHAPTER 1 Cell Injury, Cell Death, and Adaptations responses are hypertrophy, hyperplasia, atrophy, and metaplasia. If the adaptive capability is exceeded or if the external stress is inherently harmful, cell injury develops (Fig. 1–1). Within certain limits injury is reversible, and cells return to a stable baseline; however, severe or per-

There-fore, supplementation of ATP in the myocardium was initially proposed as an effective therapy for the prevention of ischemic myocardial death. However, a complete depletion of ATP within the myocar-
