I don't see the triglycerides in the report, however to answer your question triglycerides are type of fat in the body high levels of triglycerides means that your father cholesterol levels are elevated .. this does have impact and risks such as heart diseases etc also stroke. But you don't need to worry abt it so much please consult a phsycian nearby and they would prescribe the medicines for your father besides the medicines he needs to go for walks/exercise with good control over his diet such as no red meats and oil/ghee/butter. Rest this situation can be easily managed and then your father is out of the risk zone.
