Based on what you're describing — narrowed blood vessels in the pulmonary arteries (the vessels connecting your heart to your lungs) — this sounds like it could be Group 1: Pulmonary Arterial Hypertension (PAH).
In PAH, the small arteries in the lungs become narrow and stiff, making it harder for blood to flow through. This forces the right side of the heart to work much harder to push blood through. Within Group 1, there are four subtypes depending on the cause:
- Idiopathic PAH (IPAH) — No known cause
- Heritable PAH (HPAH) — Passed down through genetics/family history
- Associated PAH (APAH) — Linked to another underlying condition
- Drug-induced PAH — Triggered by certain substances or medications
Your doctor is the best person to confirm exactly which subtype applies to you, as it depends on your personal history and test results. It's always worth asking your care team to walk you through your specific classification — knowledge is power! 💪
