My husband is a Cardiologist and he doesn't think you have anything to worry about because it would have shown up in your EKG.
He said your symptoms are that of a normal muscle strain or even just gas so the blood tests weren't necessary. The blood tests may have just picked up abnormalities in blood which may indicate cardiac stress but with a negative EKG & chest xray they weren't needed. If you had a history of cardiac issues, he would have order blood tests regardless of insurance.
If your EKG and/or chest Xray where consistent with a cardiac issue, you would have been admitted to the hospital for 24 hour observation and attached a telemetry monitor. Then referred to a Cardiologist who would have likely put one on you to monitor your heart for about 2 weeks where the cardiologists gets reports from the telemetry monitor attached to you through a phone connected to it that transmits the data to them. He had a patient with one this morning that he called them at home and told them to have someone drive them to the ER and meet him there, he had a room ready for them in the ER because of the reports he was getting from their monitor, he ended up putting a pacemaker/defibrillator in them a few hours later.
Also, while the ER/Urgent care physician was your attending physician a Cardiologist is who actually reads the EKG & Chest XRay results and makes the determination whether or not to admit you, not the ER/Urgent care physician. If additional tests were needed the cardiologist would have ordered them. So whatever cardiologist they consulted didn't find it necessary.
Age is irrelevant with a heart attack, he's treated children who've had them.
