What Causes a Heart Attack?

What is the leading cause of heart attacks worldwide?

Atherosclerosis.

That’s athero, which talks about the vessels in our heart, plus sclerosis, which means fibrosis of those vessels.

Atherosclerosis is the leading cause of heart attacks worldwide. Understanding how this disease can lead to an attack starts with how your immune system works both for you and against you.

The good news is that thanks to medical advancements, people are living longer and surviving in the face of this disease.

So what are the symptoms of a heart attack? Symptoms of a heart attack include pain down the left side of your arm, shortness of breath, nausea and these are all associated with that cutoff of blood flow to the heart.

Risk factors for atherosclerosis and heart attacks include things that you can control like smoking, obesity, and diet—especially cholesterol. And some you can’t control, like age.

Cholesterol is a type of fat that’s made by our liver, and also absorbed from animal-derived foods. And there are two main types—HDL and LDL, commonly referred to as “good” and “bad” cholesterol. The bad cholesterol builds up on the walls of your arteries, increasing your risk of a heart attack, while HDL or good cholesterol works to clear bad cholesterol out.

On this episode of SICK, we sat down with DeLisa Fairweather, a PhD researchers in Jacksonville, Florida working at the Mayo Clinic, to learn more about the most common cause of heart attacks worldwide. Watch to learn more.

One avocado a day helps lower 'bad' cholesterol for heart healthy benefits
New research suggests that eating one avocado a day may help keep 'bad cholesterol' at bay. According to the researchers, bad cholesterol can refer to both oxidized low-densitiy lipoprotein (LDL) and small, dense LDL particles.

Evidence Of Heart Disease Found In Mummies
Atherosclerosis, or a disease of the arteries characterised by the deposition of plaques of fatty material on their inner walls, has largely been thought of as unique to modern Homo sapiens as a result of our modern high fat, high carb diet, higher stress lifestyle, and ever industrialising environment. However, the HORUS Study Group found back in 2013 that atherosclerosis existed at least as far back as 4000 bce. Furthermore, out of 137 mummified remains from 16th century Greenlandic Inuit communities from 3 continents across wide variations in lifestyle and heritage, 34 were found to have arterial calcification proving that heart disease has been an undeniable issue amongst our species far longer than anticipated and its factors may be more complicated than originally assumed.

New imaging modality targets cholesterol in arterial plaque
Cholesterol in plaque, along with fat, calcium, and other blood-transported substances, can lead to atherosclerosis, a disease which can cause heart attacks or strokes. Early detection of cholesterol can lead to earlier treatments and improved health outcomes. Toronto-based researchers have demonstrated a unique detection technique that combines laser photoacoustics, a hybrid optical-acoustic imaging technology, with low-power continuous wave lasers and frequency-domain signal processing, in an approach known as photoacoustic radar. This advanced technology can accurately evaluate plaque-based cholesterol, and allow for more timely treatment of atherosclerosis.

The amount of times I've had a random pain and/or numbing feeling near one of my blood vessels, and simply pressed and rubbed it for a second to make it feel better is incredible.

[abc_cba]

*Saw my mom die right before me*
No symptoms, no pain. I cry all the time seeing her empty bed and chair.
*I wish I knew about :*

1) ApoE genes to change her diet accordingly.

2) Knew that inflammation is the main cause of it, hs-CRP levels should be monitored.

3) Homocysteine should always be low, to lower it go vegan for a few days and supplement with Vitamin B-12, B6, Folate, Riboflavin, know your MTFR genes first though.

4) You should know your Ferritin levels, Iron levels and keep them low.

5) Lipoprotein A, LP(a) is a gene that 1/3 of Americans and 1/2 of people in India have, this is an independent most dangerous factor for those who carry it.

6) Know your sex hormone level, testosterone and estrogen are made of cholesterol but after 50, you won't make that much of those hormones and that would lead to useless Cholesterol build-up.

7) Those with low 25 Hydroxy Vitamin D3 are prone to heart issues as well as depression.

8) If you're above 60 you might have unnecessary Calcification of your arteries, supplement with Vitamin K-2 (MK7) and Vitamin D3, get a CAC test before and discuss with your doctor.

9) Cut down on simple carbs as they generate high triglycerides in most cases which causes high VLDL
and partially hydrogenated oils entirely.

10) Consume monounsaturated fats like Olive oil and nuts and seeds they help reduce LDL levels.

11) LDL particle size with small dense particles are dangerous, go for a CIMT test.

12) Check your TMAO levels, they are created from animal sources and also lead to atherosclerotic plaque in many cases, go vegan and see if it works or not.

13) Mother nature has gifted us with plant based antioxidants like Quercetin, Kamperferol, Apigenin, Luteolin, Rutin search for they wonderfully they work.

14) Check if you have lactose or gluten sensitivity as this has many things to disrupt your body.

15) See if your thyroid level is normal, those who hypothyroidism have high cholesterol levels and those with Hyperthyroidism die with sudden strokes due to arthymia.

16) End Table sugar consumption entirely, this is a poison.

17) Advanced Glycation End-Products generated from dried and smoked and burnt food coagulates and binds with the protein and ages you as well as disrupt your hormones.

18) Reduce your salt intake, this is the cause of 70% heart failure cases, excessive sodium leads to heart failure.

19) Go Indian, most of our spices are rocking the world with research, Turmeric (Curcumin), Clove (Eugenol), Pepper (Pipperine), Ceylon Cinnamon, so much more.

20) People who consume chillies have less heart attacks.

21) Check your blood pressure levels, this causes abnormalcy in the heart .

22) Stop heating the oils at high temperatures, this results in their oxidation also never keep the oil exposed to air or light.

23) Going Keto would help if you know your APOE genes, but keto is always better than a low fat, high carb diet.

24) Intermittent Fasting is the best way to deactivate NF-κβ pathways, stay away from inflammation.
Medical supervision is very necessary for this.

25) Try researching on NAD+ and how Vitamin B3 derivatives help keep our body stay young and healthy.

26) Stop going to restaurants they all feed us poison. So many products are sold with regulations and they sell us products laced with harmful ingredients.

27) Search for how to up your Glutathione, Superoxide Dismutase, Co-enzyme Q10 naturally they protect us

28) Vitamin C has been hypothesized to be lowest for people with heart disease, supplement it.

29) Vitamin E in the form of Tocotrienols is also very essential for heart health just like tocopherol, natural sources would be Anatto, Rice bran oil (i don't prefer Palm oil).

30) Teas like Black Tea has Theaflavins while Green Tea has that have been proven to aid heart and protect us from cancer.

31) Eat Pomegranate and Beet they boost nitric oxide to the levels of medications, pomegranate Whey fermentation makes it even 10 times better thn Red wine (search on Google).

32) Don't follow the fad diets Keto, Carnivore, Vegan entirely, a balance of all nutrients is necessary, because most of the health protection comes form Vegetarian sources but yes, i don't support veganism either.

33) Check your fibrinogen levels if you have heart patients in your family.

34) Stop smoking, this thing has killed so many people.

35) Stop being silly, if you think that some people died with lung cancer without smoking and some who do smoke are still living, well, that's because of so many factors that are not researched, don't play this Russian roulette game with yourself.

36) Keep doing work all the day and exhaust yourself. This would keep your body and lungs happy (bit not very strenuously) yet keep yourself from being lazy couch potato.

37) Do you know that if you have High/low clotting factor then you need to take it seriously ? High would result in random heart attacks, low would lead you to have other kidney diseases.

38) Check your remnant cholesterol that is more dangerous than LDL levels.

39) There are some who believe LDL to be lower than. 60 mg/DL be wise, this can lead you to have dementia because all our cells are made of Cholesterol, it's not the culprit entirely.

40) Stop mixing carbs+ protein and carb + fats, that's a dangerous combo. Carbs glycate and disturb everything

41) Know about krill and fish oil and their EPA and DHA proportion they work for reducing heart issues that is with the cost that they deactivate SIRT1 pathway and lead to use being susceptible to cancers, in theory, don't panic when you read this.. it may or may not be true.

43) Prolong fasting eats up zombie cells and reduce the macrophages that cause heart attacks, my theory is that it can reduce inflammation as well. Do yiur research.

44) Get your Circadian Rhythm on track, sleep early and wake up early. This sets up proper melatonin levels and keeps you from aging, don't you know that those who don't get adequate sleep die early ?

45) Eat soluble fibre that binds the cholesterol and clears it, example like beta glycans from barely, oats, wheat, flax, etc.

47) If you prefer nature, many fruits like Bergamot, Amla powder, have been known to ease the cholesterol issue.

48) Get love from someone it can your parents, friends, animals, this works psychologically, and calms you.

49) Do some research on Hydrogen water, I'm not sure if it works but I'm only suggesting you guys.

50) ox-LDL can kill you, it's not LDL and if you think statins are saving you, no way ! They're only fooling the liver to stop preparing cholesterol, which can cause bile stones, once you remove yourgall bladder by operation, you'll forever have cholesterol issues, that's a trick most doctors trick you to get that operation done to never grow bile stones again. Because, bile stones are not calcium but actually cholesterol particles. Be wise.

51) Get adequate light, light activates EZ electron activity. But it should be very early morning light, not the one with UVA that games us or UVB that burns our skin. Our cells live on e- (election transfer) charges.

52) Generate mitochondria by taking ice cold baths for a few seconds or by taking Infrared Suana or fasting for a prolonged time. Higher mitochondria is a powerful thing to regenerate our cells.

53) Compounds like Pterostillbene, Resveratrol have been researched to protect us from age related diseases.

54) Check your interleukin formations, High IL-2 and IL-6 triggers many malfunctions in the body.

55) There's a simple test called as ankle brachial index test, Google it and it is the easiest test to check the blockage in the peripheral veins.

56) Spanish researchers have proved that taking hypertension drugs at nightime saves us by a span of 6 years over daytime intake. Google that.

57) Magnesium is needed by the heart to pump properly, so is Potassium, but check your kidney function before supplementing.

58) Copper, zinc, Selenium and Magnesium are the cofactors needed for Cellular activities in around 1000+ enzymatic activities, check that out for heart health too.

59) gum diseases are direct causes to heart attacks as the periodontal bacteria found in gums is found at the site of blockages always and that's how the relation exists.

60) There are some adaptogens which renew the cellular respiration some even are mild nootropics like Tulsi, while some like Gotu kola can be used with Pycnogenol to clear blocked arteries, search them.

61) Troponin T is one blood test that immediately confirms if you're under a heart attack, ask your doctor for it if you have sudden chest ache or discomfort.

62) Women dont have pain as a sign of heart attack and it can feel like acidity or a chest burn in 50% of female heart attack victims. Be cautious with this fact.

*always take an advice of your doctor and don't blindly follow me, this way would educate you and maybe help you with somethings that may or may not be good with you*

All the Best with your life. Pray for my mom's soul.

me: *when you feel your pocket and your phone is not there*

[alicecolleenflynn]

The nutrition claims in this video is out of date.

[Jake]

Only around 20% of your blood cholesterol comes from diet.
The leading risk factors for heart attacks is not cholesterol levels, diet or high blood pressure, but lifestyle, stress, fitness, hormones, anger, over exertion, certain types of illness among others.

[craigsommers]

Bad and outdated info. They don't even mention the fact that most of the Plaque is calcium.

[sebwilkins]

So avoid foods which cause inflammation, something which wasn't mentioned in this and the primary causes of inflammation and high cholesterol are animals products such as milk, cheese and red meats. So limit consumption and exercise, also adopt and eat a greater amount of fibrous food.

[MathusalaTree]

No the nutrition claims aren’t out of date. They didn’t even really make nutrition claims, they explained the established pathophys.

[extrnalsorce]

When you reach for your door but it’s open, and the split second before you fall your life flashes before your eyes.

[TheFinktron]

The recent ORBITA study questions the value of stents and bypass surgery. Very controversial among the experts now.

[HandsomeBoyGarion]

Here because I been having problems with my body

[catalinacurio]

We need to educate parents to look after their kids health better. Have your treats but make them just that, a treat.

[blkd]

Cholesterol isn't the problem, sugar is it causes cholesterol to go bad😤 I thought we were done hearing this nonsense

[nelsonlouis]

This series is so good and I really appreciate all the effort it took to make this series. It makes studying interesting. Just know that you are making better students bit by bit

[TheRosiebeam]

Wow increasing human lifespan... Increase time we spend at our prime

[terryadams]

The title of this video should be called, The effects of a heart attack.

[wheelmangames]

That opening music made me think this was an Ad for the first minute...
