Hello thanks for posting at HCM. I have gone through your description. The right thing was done by doing an angioplasty at that time. Now regarding the other blockages, since you had blockages less than 70% you were kept on medical management. Angioplasty cannot be done for blockages less than 70%. There is no way to clear all blockages of the heart. Blockages once they appear can be stopped from progressing, but not cleared. An angioplasty can clear the blockages but again by pressing the blockages against the stent. Since its many years since your stenting, I recommend you to undergo a yearly treadmill test to see whether the stent is patent or if other blockages have increased. If the blocks have increased in severity then angioplasty with stents should be done. In the meantime please continue with blood thinner medications, cholesterol medications and your other regular medications. Wishing you good health. Regards
