Why alcohol is bad for your heart?

How does ethanol bring about vasodilation?

The control subjects had a significant increase in forearm blood flow (1.12 +/- 0.2 ml. min-1.100 ml-1) and skin temperature (finger 2.4 +/- 0.4 degrees C, toe 3.4 +/- 0.3 degrees C) after ethanol. These data suggest that ethanol may induce peripheral vasodilation by modulation of central vasomotor control mechanisms.

What does alcohol do to your veins?

At levels of initial intoxication, alcohol works as a vasodilator, causing blood vessels to relax and expand. However, at extremely high levels, alcohol works as a vasoconstrictor, causing veins to tighten and constrict. Both of these conditions can negatively affect your blood pressure.
