I'm a 35 year old male 6" tall and 72 kg (skinny). I have been hypothyroid (with some hashimoto's antibodies detected years ago) for more than a decade that I know of, and most likely for most of my life.
What has been particularly bothering me for the last 3 years is on and off heart attack type of feelings. This is where I feel tight or pain in my chest together with dizziness as if I don't have enough blood supply to my brain. Sometimes I go to bed feeling fine but wake up in the morning with these feelings. I can still operate, but it's definitely scary.
I never had this before 3 years ago, when this suddenly happened at the gym in the middle of an intense workout.
I have been doing research and tests and so far have been characterising this as anxiety attacks. I've had a brain MRI, heart ECG, heart echocardiogram. All these were fine albeit ECG showed slow heart rate. However, lately someone at work had a heart attack and a quadruple bypass found by a test called heart angiogram. So I have started to wonder if I need that or similar to evaluate my heart artery state. Could it be that I have a partial blockage now? I know I have elevated cholesterol due to hypothyroidism (and I do know there can be a connection).
Any advice on this? Has anyone had similar experiences? Has anyone got angiogram or similar?
