Abstract
BACKGROUND
To date there has been only one published report pertaining to the outcomes following open-heart surgery in Australian aboriginal patients.
METHODS
The records of 57 consecutive aboriginal patients who underwent open-heart surgery at our institution over a 6-year period were retrospectively reviewed. Attempts were made to contact the patient by telephone, by letter, through their listed next of kin, general practitioners, community nurse or through the aboriginal liaison officer.
RESULTS
There were 38 males and 19 females. Forty-five patients had coronary artery bypass grafting, 10 had isolated valve procedures while 2 had a combined operation. Mechanical prostheses were used for all valve replacements. There was a high incidence of diabetes, hypertension, hypercholesterolemia and smoking. There was one hospital death. Follow-up ranged from 6 months to 6 years with a mean of 3.09 years. Forty-four of the 56 (78.6%) hospital survivors were contactable while 21.4% were not contactable. There were two late deaths. Of the coronary patients who could be contacted, only 79% were taking Aspirin and a similar number Statin. 23% patients had recurrence of angina. There were five episodes of anticoagulation related complications in three patients. Only 44% of the patients were conversant with anticoagulation.
CONCLUSIONS
The follow-up of the aboriginal patients was disappointing. The compliance with the medications was sub-optimal. There was a high incidence of recurrence of angina and anticoagulation related complications. The results raise concern about the use of mechanical prosthesis in these patients.
