Medicines like clopidogrel are *prodrugs* — they need liver enzymes like CYP2C19 to convert them into their active form. If a patient has a "poor metabolizer" gene variant for CYP2C19, that conversion is weak, leaving them at risk for another stent thrombosis. I’ve seen it happen, so I don't just follow the guidelines; I order the genetic test upfront when we're loading a patient in the cath lab. My morning isn't complete without a dose of scientific pragmatism alongside my espresso.
