For some cardiac patients, recovery from a common heart procedure can be complicated by a single gene responsible for drug processing. The risk could be lowered with the first bedside genetic test of its kind. The test shows promise for quickly and easily identifying patients who need a different medication.
After a patient receives a heart stent—a small scaffold that props open an artery—his or her doctor will prescribe a blood thinner to prevent platelets from building up inside the device. However, for some 70 percent of patients with Asian ancestry and 30 percent of patients with African or European ancestry, a single genetic variant will prevent one of the most commonly prescribed blood thinners from working. Alternatives exist, but they are more expensive, so hospitals could use an easy way to identify who does and does not need the more expensive drug.
