What condition may contraindicate the use of PCI?

The use of percutaneous coronary intervention (PCI) can be contraindicated in cases where the patient is in a coma. This condition impedes the patient's ability to provide informed consent and may complicate the overall management of the patient during the procedure. In addition, patients in a coma may have altered hemodynamics and are often critically ill, which can increase the risks associated with PCI.

Other conditions, such as severe hypertension, may require careful management but do not directly contraindicate PCI, as the procedure can sometimes be performed after stabilizing the patient's blood pressure. Fever generally does not preclude PCI but may indicate an underlying infection that requires assessment. Stable angina, on the other hand, typically indicates a less urgent consideration for PCI, as it suggests that the patient is experiencing predictable chest pain that is not currently life-threatening. Therefore, the presence of a coma presents unique challenges and implications for safety and consent, solidifying its role as a contraindication for PCI.
