English to Italian Medical Medical: Cardiology esami del cuore, angiotac

So, early one morning in June, I went for the test. While I
lay on the gantry outside the C-shaped
scanner, a tech inserted
an IV in the back of my hand. The scan would have to resolve
millimeter-sized
plaque in a grapefruit-sized
organ moving at a
velocity of 200 millimeters per second. I was given an intravenous
beta-blocker
to slow down my heart to reduce image blur.
A nitroglycerin tablet was also placed under
my tongue to dilate
my chest arteries so the scan could visualize them better. After
a couple
of preliminary images, a nurse injected X-ray-

Dr. Trost reviewed the images, she called me into the
reading room. The gray-and-
white
pictures were
up on a large
monitor. White specks, radiographic grit, were
in all three of my
coronary vessels. The main artery feeding my heart had a 30 to
50 percent
obstruction near the opening and a 50 percent
blockage
in the mid-portion.
There
was minor plaque in the other
two arteries, too. Sitting numbly in that dark room, I felt as if
I were
getting a glimpse of how I was probably going
to die.
