Why are trans-fatty acids avoided in the nutrition of myocardial infarction?

What are trans fatty acids?

Trans fatty acids (trans fats) are made through hydrogenation to solidify liquid oils. Heating omega-6 oils such as corn oil to high temperatures creates trans fats. Trans fats increase the shelf life of oils and are found in vegetable shortenings and in some margarines, commercial pastries, fried foods, crackers, cookies, and snack foods. Intake of trans fatty acids increases blood LDL-cholesterol ("bad" cholesterol), decreases HDL cholesterol ("good cholesterol"), and raises the risk of coronary heart disease.

Please do not be seduced into the market's distraction of adding complications to the simplicity of our anatomy...fats are fats...getting a grip on how much you stuff into your body is key--it's called moderation (self control).

Fats are where toxins are stored first...bodies just don't know how to rid themselves of these chemicals, so they stick them into the fats until it can adjust accordingly. In the mean time, when these fats are used for energy, the body now releases these toxins into the blood stream once again...what to do? Alot of it is latched onto arterial walls, creating blockages (causes heart dis-ease)...else it is attached to cartilages about the body, like spine--esp. the base of brain, & joints...answers for most other aches & pains.

We can hardly avoid ingesting poisons these days...it's in our foods, our waters, our air...and as life is in the midst of adjusting to these new ingredients, the best we can do to maintain a strong species is to use the body you are given... read those labels--pet foods, too...find out the lineage of industrial company holdings, and no longer support the use of toxic chemical use--it is an unnecessary technology...you do this through your consumerism. Along with learning about your own anatomy, gaining understanding that a body is a whole organism & should not be treated by parts, and discovering where your foods come from & what is necessary for a well running machine...these are lessons in life skills...Have at it, and never have to worry about the health of hearts again!

Went off into a bit of a rant, but I hope you see the circle of things...

To answer your question, this is because these fats are the worst for raising your bad cholesterol. If you have suffered a
myocardial infarction you want to keep your heart at the least risk. Do they know the cause of your MI?
Best wishes for good health.
