Does adrenaline dilate or constrict coronary arteries?

Well it's a bit more complicated. What you should know is that local mediators are more important for coronary blood flow then nerve stimulation. So in this case it's as follows: Adrenaline causes the heart to increase the heart-rhythm. Increased rhythm causes increases oxygen need for heart cells. So local mediators causes the coronaries to dilate. To sum up, adrenaline will theoretically cause coronary constriction but in practise it will cause dilation (due the increased heart activity) For acetylcholine it's the same (in the end it causes coronaries to constrict due to the decreased heart activity)


Why vaccination is not effective in control or prevention of most heart diseases?

Vaccines are for specific bacteria or viruses that cause diseases. Most heart diseases are caused by other factors like narrowing of the coronaries. This is often caused by plaque build up and not a microbe. Other causes of heart diseases are similar in nature and again are not caused by microbes.

What is transmural pressure?

Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
