What kind of damage causes the heart to create scar tissue?

At least we dont get heart cancer so easily

>Athlete's heart is a result of dynamic physical activity, such as aerobic training more than 5 hours a week rather than static training such as weightlifting. During intensive prolonged endurance or strength training, the body signals the heart to pump more blood through the body to counteract the oxygen deficit building in the skeletal muscles. Enlargement of the heart is a natural physical adaptation of the body to deal with the high pressures and large amounts of blood that can affect the heart during these periods of time. Over time, the body will increase both the chamber size of the left ventricle, and the muscle mass and wall thickness of the heart.

Okay, so as long as I don't get a heart attack, I'm fine?

>>11033576
You still get lots of blood fat deposits that turn your heart into a sclerotic stone

>>11033399
Cell organs do generate new cells from old cells. What they don't do is to "fill the space" if some organ cells die 'spontaneously' from damage, disease etf

>>11033584
How can I make sure that doesn't happen to much?

>>11033599
eat more gooder
cardio
cut down on salt (don't eliminate it)
cholesterol bad

>>11033399
Interesting fact: When your heart stops for good you die.

>>11033399
This is why i never work out in order to keep my heart from usage/deteriorating

>>11033576
marathon runners have extremely scarred hearts

>>11033626
What about bodybuilders?

>>11033399
>tfw i already had two heart malfunctions and i am in my 20s
I´m not gonna make it

>>11033603
>>11033626
Ok, I'll try my best. Thanks, Anon.

No regeneration - no cancer

Heart cells have some degree of turnover and indeed heart stem cells do exist.

What should bother you is that a neuron dying for whatever reason will never be replaced and day by day neuronal cell loss will slowly bring you to idiocy.

>>11033636
Nice

>>11033659
also no alcohol, no smoking, cardio

>>11033636

>>11033728
>no cardio
Are you fucking retarded? I hope you're not focusing on this scarring 'issue' as a critical matter for your life choices. Exercise through most sports far outweight the drawbacks of this whole heart scarring autism.
Go ahead and keep vegetating. Stay sedentary. Let's see how your life span compares to the longevity of a person with an active heart.
>MUH SCARLESS HEART
While the highly efficient and healthy heart of an athlete rests at 40 BPM, yours are at 90+.

Get rekt.

Why???

>>11033399
What do you think skeletons do? Other than be spoopy of course.

>>11034067
Boston Robotics is going to integrate this into their robots so they can simulate the pain and humiliation when they're kicked over.

>>11034034
increases risk of heart attack

So, an hour a day of cardio is bad? How am I suppose to lose weight then?

>>11033399
>What the fuck

Life exist to make more life.

The body exists just long enough to raise children any longer is a waste of resources the children could be using.

Your body is designed to last just long enough to make sure your descendants are surviving.

>>11033728
not too much cardio tho
>>11034177
nah that's probably good

>>11033837
Dude the post was precise.

Serum cholesterol != dietary cholesterol.

There is conflicting evidence, at best, of dietary cholesterol increasing your serum cholesterol. Trans fats and processed foods in general are pretty well linked to it, though, as is obesity.

>>11033399
really regret trying coke

>>11033399
Want to get you mind blown?
The process of dying starts the moment you're born.

>>11033399
if u think about it, your heart could stop at any moment.... any moment now ...

>>11034820
This is not true. It starts when you are 16 approx

>>11034067
the fuck is going on here?

Lift weights.
Muscle eats fat, no need to over do the cardio.

"for a third of the people who have a heart attack, their first symptom is their last"

>>11035186
Not everyone can build muscle

>>11033399
>>Basically meaning that your heart, more than almost any other organ is always dying and getting more and more damaged
No, the brain is far worse. Neurons never regenerate. They can only form new connections, but if you lose them, they are gone.

>>11033619
False. There are several people living right now with completely artificial hearts. One of them is known for not having a heartbeat at all because his machine doesn't "pump" like a heart.

>>11033468
Lifting instead of running seems like a good alternative for heart health.

>>11033603
>worst advice ever given
Cardio will fuck your heart up
Low electrolytes make heart work harder
Cholesterol is a building block for hormones and brain tissue, so good luck on quitting it.

Instead:
>Eat meat
>Limit carbs
>Lift 3-5times/week
>Provide yourself enough salt, especially if having Northern-European ancestry
>Lots of egg yolks and don't bother about anti-cholesterol fad campaign

>>11033826
Or simply replace cardio with weightlifting.

>>11035700
cardio makes your heart stronger, it's the only reason my father survived his heart attack
excessive sodium consumption increases blood pressure, which causes heart damage
there's good cholesterol and bad cholesterol

everything you said except the egg thing is also good advice, a mixed weightlifting and cardio campaign to promote "general fitness" is ideal

>>11035447
COPE

>>11035705
Which kind of cardio your father has done?

>>11035716
he's a triathlete, he mostly limits himself to half-ironmans, although he runs full marathons and does centuries on his bike, just not all at once

>>11035705
Also I didn't meant excess of salt, rather keeping it in a healthy range and not unnecessarily keeping it artificially low.

Check:
>The Salt Fix by Dr. James DiNicolantonio
Well researched scientific take on the topic of salt.

>>11035723
>cut down on salt (don't eliminate it)
that's what I said you nigger

>>11035721
Good for him.
Before I've done a lot of running, but tend to overdo it.
I guess keeping it more functional and dynamic could be the way to get the best out of two worlds(cardio/lifting).

>>11035730
I think he's a crazy bastard but the man was walking around on half a heart for a month so what do I know

>>11035725
Cutting down means lowering intake.
Most people will take this advice as not adding salt to their food and therefore not providing enough salt comparing to their body needs.

You've an awesome dad anon

>>11033399
Not if I can create a time-space warp field around my body

>>11035737

>>11033728
No alcohol at all? Or is the occasional night out alright? I thought alcohol was only really shitty if overdone.

>>11035702
Both are excellent. Powerlifting also drastically increases cardiac resistance due to its repeated explosive nature.

terrible idea

>>11035468
not completely true. adult neuroneogenesis exists, in some brain areas.

>>11035700
>>Eat meat
yeah you gotta feed your tumors

>>11036777
Why?

>>11035700
>Cardio will fuck your heart up
t. sedentary

>>11033399
Just wait until we make you an axolotl heart. No scars, just healing.
Also, let's cross our fingers and hope this doesn't give you tumors.
