Cellular energy balance

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.
