My wife just had an episode 2 months ago. Started off with “pressure” in the chest which she attributed to heat and humidity (90’s of both). Her neck and arms were sore which she attributed to exercising the day before. That was at noon. At 9:30 at night, the pain in the arm had moved down to her forearm. My step-son who is an NP asked if she was feeling okay. Her response was that her chest has hurt all day and there is a pain in her arm and she was going to bed to see how it felt in the morning. He said no, when you have those symptoms you don’t go to bed, you go to the hospital. He called an ambulance. The EMTs did an EKG and saw some oddities on it (which my step son confirmed). They took her to the hospital ER. The next day they took her to the cardiac care ward for a heart catherization. They found 90% blockage in one artery and 99% in another. They installed two stints right then. She is fine now. They say that officially she had a heart attack, but it was very minor and did no damage to the heart. When you feel these things, go for medical help ASAP. Do not wait.
