Dave can I ask what the symptoms were?
Glad you're ok.
early in the day while catching second flight, shortness of breath, chest tightness, fatigue and minor chest pain that I thought was from eating McDonald's. Later in the evening my chest got tight, pain just to left of center of sternum and some pressure like I needed to burp. after 30 min of trying water and Rolaids, pain was increasing, couldn't find a comfortable position to sit or lie down. Pain started radiating to left side and jaw, started getting nausea and was having trouble concentrating. So i grabbed my phone, wallet, and room key and had the front desk call the ambulance.
I tell people I am the poster boy for go early. If you catch the issue before the artery closes then you stand a very good chance of avoiding heart damage.
In this case I have been bouncing off the walls because I feel so much better.
