People think I'm nuts when I cite modern day central heat and air playing a role in the decline of vascular disease after 1970.
Few people had central air before 1970, if they had A/C at all. The growth of central Air coincides with the decline in heart disease in the US. Of course association doesn't prove causation, but there may be a link.
We know that heart attacks are more likely to occur in extreme temperature conditions, hot or cold. But it may go beyond that.
Central A/C cleans the air. Not just the main dust filter, but thru condensation on the evaporator coil taking out the fine particulate and sending it out the drain pipe in a trickle of water.
Cleaner, dryer, more dense air is inhaled by the occupants, improving artery health.
Ironically, I was also in Minnesota when I had my unexplained chest pain. Urgent care couldn't figure it out. Only when I went to ER at Methodist Hospital in St. Louis Park did they catch it.View Thread
I was in similar situation to you. Mine turned out to be Pericarditis which took three trips to the doctor to figure out.
Each trip they did an EKG, and the pericarditis failed to show up on the EKG. It wasn't till the 3rd time they nailed the diagnoses with certainty.
Like you, mine was triggered while lying down. The horizontal body postion compresses the pericadrium against the chest wall. ( this is the explanation they gave me) triggering symptoms.
Two causes of pericarditis were quoted. Viral or bacterial. But they didn't quote me the 3rd cause which is low thyroid hormone. Thats what mine turned out to be. My TSH lab of 8.0 went ignored, and I was living with hypothyroidism and didn't know it.
While anti inflammitory drugs relieved the symptoms, treatment with thyroid hormone ended the attacks for good.
Wish you the best in finding the answer to your chest pain.
