Suggestion for in-hospital therapy of patients with acute coronary syndromes (ACS). If transportation times are too long, then the thienopyridine loading dose should be administered pre-hospital, depending on the planned reperfusion strategy. If thrombolysis is planned, the initial clopidogrel dose depends on age. (PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction; NSTEMI, non-ST-elevation myocardial infarction.)
