I have a question
I read that Nitrates help patients with angina due to several facts
1- it decreases the after load by dilating the arterioles which reduces the peripheral vascular resistance ( that I do understand )
2- it decreases the preload by dilating the veins which decreases Venus return
Here comes my question
Whenever we dilate a vein that decreases the pressure but increases the blood flow am I right ???
If that's right how come we increase the blood flow but still decreasing the venous return ?
Thank you
Looking forward to your answers
