What is atherosclerosis?
arteries become clogged with fatty substances called plaques, or atheroma.
What is angina?

What is thrombosis?
when blood clots block veins or arteries (final step in hemostasis)
What is inotrophy, chronotrophy, dromotrophy and lusitrophy?
inotrophy - contractility
chronotrophy - heart rate
dromotrophy - rate of conduction
lusitropy - rate of relaxation
