On Saturday March 21, 2026, I walked into the Shasta Regional emergency room with chest pain. I…read morehave a history of coronary artery disease and eight coronary stents placed over the past 20 years. I told them this. My EKG and initial troponin were negative, and from that point forward I was invisible. I sat in the waiting room for four hours. No monitoring. No IV. No serial troponin draws. No cardiology consult. No one came to check on me. No one told me what was happening or how long I would wait. I was a cardiac patient with eight stents and active chest pain, sitting in a plastic chair next to everyone else. After four hours with zero treatment or communication, I left. The next day I went to Mercy Medical Center by ambulance. Within hours I was in the cath lab. They found a 99% calcified occlusion of my right coronary artery -- so severe that a balloon couldn't open it. The vessel cracked during the procedure. They had to use a cutting balloon and place a stent to save the artery. My troponin was zero. That means my heart muscle was starving but hadn't died yet. I caught it just in time. If that last 1% had closed while I was sitting in your waiting room with no monitor and no IV -- I would have had a massive heart attack in a plastic chair with no one watching. I understand you are understaffed. I understand the ER is busy. But a patient with eight stents and active chest pain is not someone you park in a lobby and forget about. If you don't have the capacity to triage a high-risk cardiac patient appropriately, you tell them. You facilitate a transfer. You do something other than nothing. Four hours of nothing nearly cost me my life.
