Act on both sides of the cellular energy balance
 To protect the cells from ischemia, the energy supply needs to
remain greater than the energy demand.

Conclusions
 Chronic ischemic heart disease (IHD) is still a significant
clinical burden
 IHD results from a number of mechanisms
 To ensure optimal management of IHD on top of -blockers, it
is essential to address the energetic origin of ischemia
 Trimetazidine MR is an effective drug to use in combination
with β-blockers to relieve angina effectively.
