Common complications are re-narrowing of blood vessel, clot formation at the stent site, bleeding – these are prevented by medical intervention. Other rare risks include heart attack, irregularity in heart rhythm or stroke during the surgery and tearing of the vessel. However, these are now minimised by advancement in the procedure.

Most studies report a symptomatic relief immediately in about 90% patients. Various studies which follow the patients after the surgery have reported emergence of re-narrowing in 30-40% patients after the surgery.

In most cases, heart monitoring and drug adjustment are followed thoroughly after angioplasty. Patient is able to return to work after about a week to ten days of stenting.

No heavy lifting or strenuous activity should be performed right after the surgery. In long term, Smoking should be discontinued. Diet should be modified to include less cholesterol and more of polyunsaturated fatty acids (like fish oil) and fibre. Weight reduction should be targeted and BP, blood sugar should be controlled.

An alternative frequently suggested and performed is an Arterial Bypass Graft surgery-wherein a grafted blood vessel acts as a transit for blood to bypass the vessels which are narrowed. This is, however, usually recommended when narrowing occurs in more than 1 or 2 locations as it is a more invasive and risky surgery with a longer recovery time.
