What are the chances of being completely angina-free after having a successful angioplasty?
I know that this depends largely upon the patient’s individual condition, but what percentage of patients will be 100% angina free after having a successful angioplasty? How much improvement in quality of life can I expect?
I would say the chances of being completely angina free depends on the extent of the disease ie if you have diffuse multiple blockages or one or two critical blockages.
With diffuse extensive disease, while you may improve the prognosis by treating the critical large vessels, the symptoms may still remain as many of the smaller branches may continue to cause symptoms as stents and angioplasty cannot be used in the very small branches and vessels.
Optimal Medical therapy and intensive lifestyle changes help to mitigate or alleviate symptoms in this situation in addition to angioplasty and heart stents.
With one or two critical coronary stenoses however one should expect more complete relief of angina.
The main aim of successful angioplasty is both improved survival and quality of life and you should expect a 90 to 95% improvement in quality of life following your procedure provided it is clearly established that your symptoms are caused by the narrowing in the blood vessels i.e a positive treadmill or nuclear scan test and that you do not have diffuse disease.
