We describe a case of a 34-year-old woman with chronic renal failure under haemodialysis. The patient exhibited high on-treatment platelet reactivity to gradually stronger thienopyridine regimens, including standard and high maintenance doses of prasugrel. Platelet function was monitored by VerifyNow assay and genotyping for various single-nucleotide polymorphisms was performed. Treatment with ticagrelor 180 mg/day was effective in reducing the platelet reactivity.
