Reactive thrombocytosis resulting from frequent blood donations as an extremely rare cause of ST Segment Elevation Myocardial Infarction in the case of a 19-year-old male

Introduction. Thrombocytosis is a disease where the platelet count exceeds 600,000/μl. It is usually reactive in nature, less often clonal. Reactive thrombocytosis is usually a response to reactive inflammation or infection, splenectomy, iron deficiency, pregnancy, physical effort or cancer. Case report. The case is described of a heart attack with ST-segment elevation in a 19-year-old male which was occurred due to intensive haematopoietic system renewal, caused by frequent blood donation which, in turn, caused reactive thrombocytosis. Reactive thrombocytosis is very rarely the cause of heart attack with ST-segment elevation, and is extremely rarely caused by blood donation. It is generally considered that reactive thrombocytosis is not a risk factor in the case of thromboembolic complications. Conclusion. The presented case and the literature point to the risk of serious thromboembolic incidents, including heart attack, in the course of thrombocytosis

Cohort profile. the ESC-EORP chronic ischemic cardiovascular disease long-term (CICD LT) registry

The European Society of cardiology (ESC) EURObservational Research Programme (EORP) Chronic Ischemic Cardiovascular Disease registry Long Term (CICD) aims to study the clinical profile, treatment modalities and outcomes of patients diagnosed with CICD in a contemporary environment in order to assess whether these patients at high cardiovascular risk are treated according to ESC guidelines on prevention or on stable coronary disease and to determine mid and long term outcomes and their determinants in this population
