[Does recanalisation of chronic right coronary occlusion improve long-term quality of life and the return to work?].

Between 1985 and 1990, right coronary artery recanalisation was attempted in 60 consecutive patients. In order to evaluate the long-term benefits, 2 groups were compared: group A (27 patients: 26 men, 1 woman) with an initial success; 1 patient was lost to follow-up (3.7%); group B (33 patients, 31 men, 2 women) with an initial failure; no patients were lost to follow-up and 1 patient died after secondary coronary artery surgery. After a follow-up of at least 1 year, the patients assessed their health and compared it with their pre-angioplasty state with the aid of a questionnaire. Age, initial left ventricular ejection fraction, the percentage of multiple vessel disease and the number of patients at work before angioplasty were the same in the two groups. After a mean follow-up period of two and a half years, 7.6% of patients had undergone coronary bypass surgery in group A compared with 18.2% in group B (NS); 69% of patients in group A claimed to be improved compared with only 24% in group B (p = 0.07); a bi or triple anti-anginal therapy was used in 58% of patients in group B and 42% of patients in group A (NS); however, 59% of patients returned to work in group B compared with 44% in group A (NS). Initial successful recanalisation of chronic right coronary occlusion improves the quality of life at long-term but does not increase the chances of returning to work.(ABSTRACT TRUNCATED AT 250 WORDS)
