Hello! Welcome to HCM!

Atherosclerosis of native coronary arteries is caused by acclumulation obsturctive plaques in the lumen of the the blood vessels supplying the muscles of the heart( coronary arteries). The term native here refers to the vessels that normally supply blood to heart. This is in contrast to any new blood vessels that may literally grow(a process called 'neoangiogenesis') on your heart when the native vessels are not supplying blood adequately due to blockage by plaques or you have an articially implanted bypass graft.
Angina pectoris refers to the clinical manifestation of coronary artery atherosclerosis. When the heart is deprived of adequate blood, symptomatically it is manifested as compressive chest pain especially during physical activity. Anginal pain is essentially reversible when you stop the activity.

So in summary, assuming that you have had a CT angio/ MR angio, this diagnosis means that you have developed blockages(partial) of your heart vessels but they are not clinically manifest yet. Please be advised that symptom manifestation can be sudden and severe so you should actively undertake the lifestyle modifications and medication regime as advised by your cardiologist.

Take care
