dats supposed to b a reason for heart failure, right?
I guess all were almost correct! but the more possible ones were 1,3 or 4?? not sure about '1' ..but 2 can't be because fatty deposits can't lead to heart failure...it only leads to artherosclerosis :)

to me 4 dint seem to b correct cuz it sed "risk of blood clots" clots werent formed
Clots are formed! n they cause complete blockage of oxygen supply to the heart!!!.........firstly, fatty deposits ,then plaques n then blood clots are formed leading to thrombsis
