Summary

Approx. 65% of resuscitated patients at the intensive care unit for internal medicine are due to myocardial infarction. Almost all patients are initially diagnosed and treated in the cath lab. Therapy usually consists of one or more stent implantations. After implantation of a coronary stent, dual platelet inhibition is necessary for 12 months. Insufficient platelet inhibition causes an pronounced increase in risk of stent thrombosis. Therefore, secured inhibition and knowledge of the individual platelet function is valuable.

Detailed description

Patients after successful resuscitation associated to a myocardial infarction will be included into the study the morning after the index event. Patients get dual platelet inhibition using cangrelor as P2Y12 (purinergic G protein-coupled receptors-12) inhibitor plus acetylsalicylic acid (ASS). Patients are treated with therapeutic hypothermia according to the local Standard operating procedure for 24h and rewarming is performed within an additional 5 to 20h. Platelet function is measured every morning and ASS mediated as well as P2Y12 mediated platelet function inhibition is recorded. All relevant clinical data including APACHE (Acute Physiology and Chronic Health Evaluation) and SOFA (Sequential Organ Failure Assessment score) scores are collected. The degree of platelet inhibition over time (4 days) and differences between the three drugs tested will be evaluated by optical aggregometry and by using the commercial VerifyNow test system.
