  • heart chemical???

    I have searched everywhere and can not find a thing on what chemicals/hormones your heart releases, and the symptoms.
    I have had a couple of weird spells where my chest and upper arms and upper back all feel really weird, almsot like I rubbed icy/hot all over my upper body. I got really weak and light headed and my heart was pounding a bit. I layed down and put a cool cloth on my head and in a few moments I felt better. It hit suddenly and lasted probably 2 or 3 minutes. It made me feel so sick, ugh.

    Can anyone tell me anything about the chemicals that your heart releases. What they are called, how they work etc.

    At first I thought it was a panic attack but I have never had that cool numbing feeling with a panic attack.

    I finally got in to see my cardio at the ed of this month but would like to research a bit to find out if this is what is even happening to me.

    Thanks for any info you can give me,

    Take care

    Hi Pam,
    Here I go hypothesizing again, but I never heard of the heart giving out chemicals or hormones. It’s usually the other way around. Adrenalin for example can make your heart race, give you hot flashes and pain in the pit of your stomach. It’s part of the normal fight / flight response to a situation – and shock will do it too. Maybe you should be looking for things that effect the heart, not being produced by it.

      I do not want to scare you, because everyone has different responses & symptoms. I had the symptoms you discussed, twice last spring, I didn't discuss them w/Dr (for whatever stupid reason)-then I was symptom free until it happennned again- I was in the Hospital & they diagnosed me in Atrial Fibrillation.
      Perhaps, you can talk to your Cardio, prior to your appointment, for his input? Maybe that would put your mind at ease.
      Be Well

        Burt, my Dr made a half-a$$ed comment about the heart giving out some kind of chemicals but she said I would have to talk to my cardiologist about it because she didn't know anything about it. I can not find anything on the internet about these so called chemicals so you may be right.

        Ronnie, thanks for your reply, if it was indeed AFIB then hopefully we will know soon enough. I had the same kind of spell the othe day while wearing the holter for 48hrs, I haven't heard back yet. Frankly if thats what it is I am okay with that-just need to stop them from happening, they make me feel so sick.

          I think you are talking about BNP?
          Let me know.

            I think Lisa is right. This is what I turned up with an internet search. I guess I learned my 'something new' for today. (Thank you dear heart.)

            Natriuretic Peptides
            In response to a rise in blood pressure, the heart releases two peptides:
            • A-type Natriuretic Peptide (ANP)
            This hormone of 28 amino acids is released from stretched atria (hence the "A").
            • B-type Natriuretic Peptide (BNP)
            This hormone (29 amino acids) is released from the ventricles. (It was first discovered in brain tissue; hence the "B".)
            Both hormones lower blood pressure by
            • relaxing arterioles
            • inhibiting the secretion of renin and aldosterone
            • inhibiting the reabsorption of sodium ions by the kidneys.
            The latter two effects reduce the reabsorption of water by the kidneys. So the volume of urine increases as does the amount of sodium excreted in it. The net effect of these actions is to reduce blood pressure by reducing the volume of blood in the circulatory system.
            These effects give ANP and BNP their name (natrium = sodium; uresis = urinate).
