Angina pectoris is chest pain/discomfort caused by reduced blood flow to the heart, in a condition known as myocardial ischemia.
Signs and symptoms: squeezing pain or heaviness in the chest, which may also spread to the neck, arms, shoulders and back; or in the stomach area after meals. Women are more likely to experience a burning sensation. Angina is not the same as heart attack. It is associated with transient ischemia without infraction. But it increases the risks for heart attacks.
Angina is caused by the narrowing of one or more coronary arteries that supply the heart. This can result from a fixed obstruction by cholesterol plaques, or a temporary constriction due to blood vessel spasms.
There are several types of angina.
Stable angina (effort angina), the most common form, is usually caused by a fixed obstruction, a plaque. Stable angina is predictable, with familiar pain patterns, and typically prompted by physical exertion, when the heart requires more oxygen than it can get from narrowed vessels. Factors that constrict blood vessels or increase blood pressure, such as emotional stress, cold temperatures or heavy meals, may also induce angina. Unstable angina may occur unexpectedly, even at rest, with a changed pattern from the usual stable angina. It is more severe, lasts longer, does not respond to rest or medications, and is often the sign that a plaque has ruptured or a clot has formed. Unstable angina is a medical emergency as it often precedes a heart attack.
Electrocardiograms (ECG/EKG) of patients with obstructive angina commonly show ST-segment depression during attacks. Diagnosis is confirmed with heart stress test. A number of patients with stable angina symptoms have normal coronary arteries on angiograms. These cases are now recognized as microvascular angina (Cardiac syndrome X), where the problem lies in tiny branches, and is therefore undetectable by angiography. Microvascular angina is much more common in women.
Variant angina (Prinzmetal angina) is caused by vascular spasms of coronary arteries. Variant angina is often severe, but responds well to medications. Diagnosis is by presence of ST-segment elevation during attacks, and provocative testing with drugs that induce coronary artery spasms.
Treatment of angina aims to relieve symptoms, reduce frequency of future anginas, but most importantly, reduce risks of heart attacks. Apart from lifestyle changes to modify risk factors, treatment options include a number of medications and surgical procedures.
Nitroglycerin, a potent vasodilator, is most effective for acute anginal attacks. Long-lasting nitrates, antiplatelet drugs (aspirin…), beta-blockers, and calcium channel blockers can be prescribed to prevent future anginas.
Revascularization surgical procedures include coronary angioplasty and coronary bypass.

Excellent lecture maam ....keep helping us🙏
I think it’s time I go to the hospital. I’ve had these weird pain attacks for the longest time and The last time I went to the hospital for it was 2 years ago and I was told I was crazy.
I’m the same as you atm . They said panic attacks? So annoying
Are you okay ?
i get this whenever i do intense exercise it sucks 😩
You guys are the best! I really like all of your explanations!
Could you guys do a video on people with ADHD and the way they process information and make connections with information in their minds?
Wtf ???? I have ADHD and that does big make sense
Well explained... Easy for understanding 👍👍
So clear, thanks!!
I have this. I'm a lorry driver. And I was getting tightness in my chest and a sore shoulder and arm. And getting out of breath just driving. But it went away after a while. Obviously I panicked at 1st thinking it was a heart attack. And got it checked out and I had unstable angina. Im only 32, quite fit. But smoked a vape and didn't eat great being on the road a lot. I'm on beta blockers now and got stints in to clear my obstructions. If u feel any discomfort with ur heart. Get it looked at.
Hi Dave I get shooting pains down my left arm even when resting and its like being electricuted ? Did you have this experience?
@@carloferrari7452 yes mate I did. Very uncomfortable. Pins and needles to. Always down my left side. Get it checked out mate.

Thank you!
This is exactly i feel most of the time, stable angina, omg!
Thnkx 4r beautiful videos
thank you
Thanks for your vedio
So WHY do I have BOTH Vasospastic angina AND diffuse cardiac fibrosis? If is doesn't cause permanent damage, then what could have happened.
Angina is getting worse over the years (happens while moving AND at rest, lasts longer, 3 doses of nitro doesn't help). All I can say is whenever an attack hits, it wears the heck out of me. And I want answers b/c it's no way to live a life.
Amazing 🤩
Thanks for your
What is the difference between microvascular angina and Prinzmetal angina?
ischemia, triggers the release of substances like lactic acid and other byproducts of anaerobic metabolism. These chemicals irritate nerve endings, sending pain signals to the brain. The pain can manifest as a tight, squeezing, or burning sensation in the chest, which sometimes radiates to the arms, neck, jaw, or back.
Thank u🙏
well said..
Thank you🙏🙏🙏🙏🙏🙏🙏
B blockers cannot be given in prinzmental(variant)Angina
Prinzmetal*

Thank you however it was hard to listening to Angina pronounced Ann-G-Nahs when usually I hear An-Jine-ahs.
I do pains but they go away as soon as I start getting back to my runnings
I'm confused
HI l have this problem in my chest shoulder and neck and my back shoulders so can you tell me PLEASE what medication CAN l TAKE THANKS
Take nitro and beta blockers
I’ve just been diagnosed with micro vascular and some variant and vasospastic angina. I had an angiogram last week which is how it was diagnosed. I have extremely unstable blood pressure I’m on a whole raft of medications to try and either stabilise it and at best bring it down and stabilise it. Whilst I was in hospital this past two weeks they had me on blood thinners and two heart drugs and it dropped my bp to my normal levels of 110/80 and it was fairly stable. However because the main arteries weren’t blocked they took me off the clopidogrel and Ranexa and an Ischeamic drug and just carried on with the beta blocker and aspirin. Within 12 hours my BP was back up to 181/115 then hour later 109/75 and within 30 minutes it’s back up to the 170’s/ 110’s it’s crazy. When I was admitted to hospital I was having to take my GTN spray 4/5 times a day whilst in hospital on the extra medication it was down to 1/2 times a day. Now I’m back to my BP dangerously high and unstable and taking my spray 4/5 times a day again ….and I don’t always take it every little pain I have, if it lasts longer than 30 seconds then I’ll take the spray. I just wish someone would really look into why my body’s doing this. I’m not diabetic, never smoked in my life I don’t drink alcohol. Yes I am overweight but in last two years I’ve lost over 3 stone, I have fibromyalgia, chronic back pain, chronic migraines, sleep apnoea, mild asthma, gastric problems which needs fixing with surgery and I’m registered disabled so not as physically active as I used to be. I wonder if a lot of my blood pressure problems stem not from blocked coronary arteries but I have some stenosis in the arteries in the back of my neck going into my head and I wonder if these are the cause of the unstable high BP?
Love from india ❤️
yea the blood pressure can definetily do it trust me that blood pressure makes ur heart work overtime and struggles doint so when it gets tired over time bad things happen
I have angina I call it acute
I woke up with an angina attack this morning. My chest was sooooo tight!! I have unstable angina. It was painful and scary! I chewed an aspirin. Took a while to stop.
yea aspirin is a daily thing
Taking aspirin in an attack is as effective as chewing a jelly baby.
Treatment of microvascular angina?
Mine was like heart
burn kept taking antacids went to hospital thinking i had an ulcer turns out to my shock it was Angina ..had angioplasty with dye showed i have four blocked arteries and need a by pass ive never smoked not over
weight traineď all my
life so total suprise you never know can be unlucky mind you I'm sixty four so lucky that they found it could of led to massive heart attack
how long was the symptoms before u finally go to hospital
3 months i had my triple by pass three weeks ago today @@patrickmwangi9983
I went to the emergency they said I was good I’m scare to go to sleep
nice vedio
how treat acurate?
went to an ER and i was treated like crap today ... the hospital i went to i had 2 not 1 but 2 repeat full cut open gall bladder surgeries as i couldn't get it done laparoscopically due to too much scar tissue from prior surgeries for a prior Renel mass and appendicitis in 2014 for a stuck gall stone in my bile duct then 3 years later in 2017 had horrible pain again same side identical to fist gall bladder pain as it turns out they only did a partial removal in 2014 so they had to remove the whole thing in 2017 due to rein infection .. well anyways lo and behold starting yesterday im having horrible pains again and it feels just like gall bladder pain again even though it's not there and it radiates to my chest bone and onto my back between the shoulder blades. no ct scan no mri only an ultra sound and blood work and urine work done ... within 5 minutes of talking to me the LPN was certain it was acid reflux NO NOT ACID REFLUX ... it feels like a clenched fist in my chest and back and while it's clenched it hurts so bad especially to breathe then it releases it will do this about 5 times or so then quits but then comes back worse everytime .. i told her nothing was working for my pain and Alievi an NSAID made it worse ..so what does she do loads me up on toradol an NSAID and gave me throat numbing solution which did nothing to help my chest and back pain but only exacerbated the pain ... she refused to give me an actual pain meds that worked not even an oral one !!! to go home with or treat me with while at the hospital but only gave me more toradol after 3 hours which made my pain so terrible then just writes my discharge as gird... i also have a heart murmur and i get palpitations a lot
It Felt Like Soo much more pain than usual and it felt like something like round and long almost got cut
Help i have chest pain and I can't breathe
Go to the hospital asap

Ishani Sarkar 👍🏽☺️
Sir how to cure unstable angina ..any suggestion along with medicines
@@Ch.Ravindra6110 I’m sorry bro I can’t suggest you single medication 💊, because I’m not experienced doctor, I’m still student... it will purely recommend you to talk with cardiac specialist
@@DrTanveerAbbas ok sir. Thanq sir.
Man I have been calling it " And-Gina" no one corrected me
Disagree with the beta blockers prescribed for Prinzmetal Angina. Calcium Channel but NOT BETA Blockers as this can further trigger this type of angina.
When I was younger, knew a girl that had acute angina
Juice Juice And Juice no heavy fatty meals. No more Korean bbq No More Tofu no more Asian MSG Foods
Bruh I’m 5’11, 200lbs and I’m 16 and I have this and this lasts for hours on end for me

Yo I only get chest pains when I’m laying down and it sounds like unstable angina, I went to the hospital and they didn’t really do anything they just told me what I have and we left.
For me my chest feels really tight and hurts so bad I haven’t been to the doctor yet, I’ll just google and I came across this video, but 🤷🏾♀️
How can I fix this
Same issue here
Chest pain when you lay down on left side or right side? back or stomach side? or does chest pain come in any case when laying?
We are Indian please in hindi
There are Hindi subtitles, just switch them on.
That's not how angina is pronounced.
You are right. This is not how they pronounce angina.
