In brief: Correlative
The LDL is like the trash bags that are left on the street weekly by the households.
The more that are placed the narrower the street. Hdl is the garbage truck that scavenges the LDL (trash) deposits. The more the HDL the lower the plaque burden. The more the LDL the higher the plaque burden.

In brief: Opposite relation
The risk of coronary artery disease is directly related to the level of LDL and indirectly related to the level of hdl.
This means that the higher the ldl, the higher the risk of coronary disease, and the higher the hdl, the lower the risk of coronary disease.

In brief: Depends on Particles
Following entry into the artery wall low LDL particles directly promote development of atherosclerosis ("hardening of the arteries") and increase risk for heart attack and stroke.
Hdl particles work in several ways to decrease atherosclerosis and cardiovascular risk. As a result, increased numbers of LDL particles, as well as decreased numbers of HDL particles, are risk factors for heart disease.
