That's a really important question, and it's great that you're staying on top of your labs ahead of your Monday appointment. A creatinine of 2.4 is definitely something worth discussing closely with your care team.
PAH itself can affect kidney function. When the right side of the heart is under strain, it can reduce how well blood flows to the kidneys, which over time can impact their ability to filter properly. Beyond Lasix, several PAH medications can potentially affect kidney function or blood pressure in ways that stress the kidneys:
- Vasodilators — these relax blood vessels and can lower blood pressure, which may reduce blood flow to the kidneys
- Warfarin — sometimes used in PAH; sudden changes in how you feel while on it warrant immediate medical attention
- Sildenafil (Revatio) — can lower blood pressure throughout the body, not just the lungs
- Sotatercept (Winrevair) — a newer PAH medication with noted side effects worth monitoring
It's worth writing down every medication you're currently taking before Monday's appointment so your doctor can review each one carefully. Seeing a nephrologist sounds like a very reasonable next step. Going into Monday's appointment with your full medication list and your lab history will help your cardiologist make the best call. Don't hesitate to ask directly which medication might be contributing — that's exactly the right question to raise.
