Imagine running 2kms in 1m59s ... that's what racehorses like Secretariat do! With training comes an increase in RV internal dimensions contributing to the most common murmur found in performance horses: tricuspid valve regurgitation. #BIOM4180

Did you know not all types of sitting have the same effect on your heart?! Leisure sitting, such as when you’ve finished the entire latest season of #MoneyHeist in one sitting, is associated with greater risk of ❤️ disease. #biom4180 https://t.co/fJdXzAXRDc

@lea_cardiology Pheww☺️ i was starting to worry for my health haha #biom4180

#COVIDー19 may be around for a while so remember to take care of your mental health. Psychological #stress is a risk factor for cardiovascular disease. Atherosclerosis and endothelial dysfunction are few of the many effects stress has on the ❤️. #biom4180 https://t.co/DZa1ia92el

A recent survey shows that #COVID19 is getting into our heads. Social bonds are being broken, businesses are closing, jobs are being lost, and the #stress is mounting. Do you agree? https://t.co/vCozc46P6c

Sadly, stem cells have a low survival rate. One team added in mussel adhesive proteins which have special properties of adhesiveness and angiogenesis. They promote regeneration by reducing fibrotic tissue and forming new blood vessels. #biom4180 https://t.co/LZO5QofH1U

(1/2) Stem cell transplant after a MI is a hot topic in research right now! Cell necrosis can occur after a lack of oxygen to the tissue. Most studies introduce exogenous stem cells to the infarcted tissue in hopes it will regrow. #biom4180

So we all know how bad BPA can be for our bodies...but how safe are “BPA free” plastics full of BPA substitutes? A study on rats found that BPA, BPS and BPF all impacted fetal growth and caused hypertension later in life. #biom4180 https://t.co/hg31sSiryH

Nobody wants to constantly relive a traumatic experience; those with PTSD do. This can cause unhealthy plaque build up in coronary arteries which can suddenly limit blood flow causing bouts of severe chest pain known as unstable angina. Learn more below! #ptsdawareness #biom4180

If you guessed blue whale you’re right! This heart weighs a hefty 400lbs and is 4’ wide x 5’ tall. Believe it or not you can hear a blue whale’s heartbeat from 3.2 kms away 🌊 🐳 Challenge yourself by naming all the heart features you can see! Pic and info: @ROMtoronto #biom4180

Imagine your mom/dad (barely able to work Facebook) is a heart surgeon and now has complete control of this robot! This minimally invasive method, with just a couple precision-guided robotic arms that insert bt ribs, is great at repairing valves. #biom4180 https://t.co/L7jFcNkLYd

After MI, 20% of hearts undergo remodeling which can cause LV dilation. Surgical ventricular restoration is a new way to restore the LV to its proper shape and volume. A mannequin is used to guide suturing the ventricle into an elliptical shape. #biom4180 https://t.co/2w2Wpia4zG

Noises louder than 35 decibels cause an increase in BP by triggering your body’s stress response. Hypertension increases your risk of developing problems like heart disease or stroke. So, add this to ur list of why ur SO shouldn’t snore at night! #biom4180 https://t.co/08v1ufqg93

[Morgann Rollin @MorgannRollin]

@macfadyen_a Chronic high levels of noise can cause oxidative stress and metabolic abnormalities causing a higher prevalence of diabetes and accelerating progression of atherosclerosis. Most studies looked at people housed by airports (graph), I can't find much about rural living. #biom4180

Saying “bless you” to someone after they sneezed began when people thought that the devil could steal your soul during the brief pause in heart beat the sneeze could cause. Nowadays, just remember to cover your mouth when you sneeze 🤧🦠 #biom4180 https://t.co/wuOq4u4jwd

[Morgann Rollin @MorgannRollin]

Sneezing involves taking a deep breath before expelling air out of your lungs at high speed through your nose to clean it of debris. The heart sits between the 2 lungs so that super deep breath can cause organs to press on and activate the Vagus nerve. #biom4180

Mathematics of visualizing sneezes & coughs:

[Morgann Rollin @MorgannRollin]

The activated Vagus nerve sends out a signal to slow down the heart rate. It’s rare, but the vagus nerve can be over-stimulated causing the heart to stop or skip a beat during a sneeze. #biom4180 https://t.co/aQA7akjokV

@bajwa_jasmit There’s the ongoing joke that anyone who uses supplement powders has “expensive pee”, but maybe adding all that protein powder to your shake has its benefits! I wonder if protein powder would be equivalent to dietary protein in this case 🧐 #biom4180

[Morgann Rollin @MorgannRollin]

@ShaniaRUofG Well it’s too bad I sit at my desk all day now. At least if I develop heart failure I can study myself for the next term test...😬😅 #stayingpositive #biom4180
