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.
