Protein C (PC) and protein S (PS) are natural anticoagulants that protect the body against thrombosis, and their deficiency, either inherited or acquired, renders the body to a hypercoagulable state. This leads to venous thromboembolism manifesting as thrombosis, pulmonary embolism and superficial thrombophlebitis among other causes. The involvement of arteries is rare and has been explained by only a few studies. Hence, the presentation of PC and PS deficiencies with stroke and myocardial infarction (MI) is rarely observed, especially in young patients. We report a case of a 33-year old male with a past medical history of stroke and MI for which no underlying cause was found. He presented now with shortness of breath and left-sided chest pain and after a series of workup, eventually diagnosed as a rare case of PC and PS deficiencies.
