Detaljert beskrivelse
This study is a prospective, randomized, open-label, active controlled study with two parallel study groups.
For inclusion in the study subjects should fulfill the following criteria:
- Provision of informed consent prior to any study specific procedures
- Female or male aged 20-85 years
- All patients with ACS scheduled for PCI will be eligible, assuming their ability to understand the character and individual consequences of participation as well as giving written informed consent.
- Be able to understand and comply with the requirements of the study, as judged by the investigator.
To investigate the effects of ticagrelor on coronary microcirculation, IMR will be measured twice, 6 months apart in the same lesion, compared with clopidogrel.
The IMR is defined as simultaneously measured distal coronary pressure divided by the inverse of the thermodilution-derived hyperaemic mean transit time (Tmn), or more simply, distal coronary pressure multiplied by the Tmn.
