    part of heart dead?
    Tiagir posted:
    A friend's fiancee just recently found out that the back part of his heart is "dead". What is this called and does anyone have any ideas on how this will continue to effect him? Thanks.

    When someone has a heart attack, heart muscle cells die - depending on the extent of damage, this will affect people in different ways.

    Hi Tiagir: b "What is this called" Typically a posterior (back wall) heart attack. Akinesis (no movement, "deadsville"). b "Any ideas on how this will continue to affect him" As applicable, what happens after a heart attack (and down the road) mainly depends on what specific area(s) of the heart muscle (myocardium) were damaged (infarcted), size and depth of the damage, and if there has been any previous damage. Some individuals do not survive their first heart attack, and more often, not the second one. Good to know, if/when a Q wave (as seen on an electrocardiogram, ECG/EKG) develops after a heart attack or MI (myocardial infarction), it is called a Q wave MI, usually corresponding to a transmural MI, affecting the entire/full thickness of the heart muscle, the worst type (has a substantially higher mortality rate). If/when a Q wave does not develop after an MI, it is called a non-Q wave MI, usually corresponding to non-transmural or a subendocardial MI, less damaging than a Q wave MI, as the heart muscle just under the sensitive inner lining of the heart is affected (lower mortality rate, though this type of incomplete MI poses a high risk for reinfarction, or completing the infarction). Cell/tissue death does not occur immediately (once the artery is 100% blocked, with no, or insufficient coronary artery collateral circulation). It takes several minutes to start the injury process, which then continues on (evolves, in phases) for several hours, unless the artery is opened up. restoring blood flow. Prompt treatment can limit the damage, but the damage that has been already done is permanent/irreversible (though some ongoing clinical trials are showing promise for making heart damage reversible). After a completed heart attack, the body heals the heart damage caused by it by forming scar tissue. This healing process is usually complete in 4-8 weeks.

    Just a layperson here - but I also had a "back part" heart attack resulting in muscle death, so I thought I would add my perspective. The cardiologist who did the angioplasty advised me as follows: The heart is a wonderful muscle and you can live with even 40% of it dead, so it has a lot of reserve. I had lost 5% of the muscle, a relatively minor heart attack, which means I had lost about 12% of my reserve capacity for the heart. Not a good thing. (Basically, in my case I delayed too long to get to the ER). I have had 6 stents implanted since then at various times, but I am fully active, golf, power walking, hiking moderate trails in the state parks, etc., and I take my meds and follow the doctor's orders rather religiously. I think the question is about how much of the muscle was lost in percentages - if it is low as mine was, his activity should not be limited, assuming he follows the advice of trained medical folks who know his situation. Good Luck To Him
