circumflex artery

hi!
last year my had an angioplast done for his left coronorary artery.At that time, he had 65% blockage in the circumflex artery..now he has a symptom of bluish lips and nails, his feet and hand stays cold and his speech is not clear. The doctor did some blood tests but has not undergone any further treatment.Is it that the doctors arewaiting for more blockage in the circumflex artery. Do you suggests any suggestions that he should do right away?

A 65% blockage of ICX should not produce the signs and symptoms you have provided.  Generally, a blockage less than 70% is not considered appropriate for intervention according to the medical guidelines.  

The symptoms and signs indicate there is inadequate blood supply pumped into the system with each heart beat. You should get the numeric value of heart's pumping capacity expressed as EF (ejection fraction).  Normal range is 55 to 75% that indicates the % of blood pumped with each stroke, and an angioplasty report should provide that information. That would be a good start to get an understanding of the heart's funcitonality.
