I have posted on here a few times recently and have had further, inconclusive test results that I thought I would put out there for anyone with medical/cardiology/electrophysiology background might be able to help me explain.
September 2006 I experienced bad chest-pain mid-race during a 5k and dropped out. In the week following, I was sent to a cardiologist where an EKG and stress test were performed. Neither showed abnormalities.
January 2015 I passed out on a flight, was taken to the ER upon landing, and my EKG showed T-wave inversion in V2 the following day on my stress test. One week later at my follow up with a cardiologist once I had returned home, my EKG was normal. Following inconclusive tests (multiple echo's, CT scan with contrast dye, etc.), I had an "implantable loop recorder" installed in my chest to assist with long-term monitoring/diagnostics.
April 2015, I flew to Denver, CO for a ski trip and my loop recorder picked up on shortened ST segment that night. I followed up with the cardiologist and electrophysiologist on my return, and they neither took further action nor indicated a possible diagnosis based off that most recent phenomena.
Earlier this month, I flew to Florida for work and flew home late on a Tuesday evening. That Wednesday evening, I experienced terrible left chest/back pain that continued through Friday afternoon when I finally went to an urgent care clinic. My chest X-ray's showed no rib/pleurisy/pericarditis issues, but my EKG showed ST elevation in V1-V3. Additional tests did not show any indication of STEMI, subsequent tests showed no plausible reason. The following Tuesday I followed up with my cardiologist; at that time, my chest pain had resolved by my EKG still showed ST-elevation in V1-V3.
I was scheduled for an angiogram and transesophegeal echocardiogram, which I had done last Tuesday. Prior to, during, and after both tests, all of my EKG's were normal (i.e. no longer any ST-elevation). The results showed no blockages, no valve issues, no coronary aneurysm. The only structural deformity was mild myocardial bridging across a branch of the circumflex artery.
My cardiologist current, best "educated guess" (according to him, as he's still unsure) is that I'm experiencing "heart spasms". He said it is rare and I'm the 4th out of 30,000+ they have seen through their clinic with such indications. He thinks these potential spasms are causing the bridged muscle to pinch the artery, mimicking heart-attack-like symptoms. I was given nitroglycerin spray to utilize next time this happens and am now awaiting follow-ups for an electrophysiologist.
My question to anyone out there who may have experience in this field: what in the world could be causing such phenomena with my EKG's at the same time symptoms are presenting? And if this is truly "heart spasms", what in the world could be possible causes.
