[Immediate and long-term results of coronary surgery under age 40].
The results of coronary artery surgery in young adults have not been extensively studied. We analysed the results of 221 patients under 40 years of age operated between 1979 and 1989 at the Pitié-Salpêtrière Hospital. The patients were 200 men and 21 women with an average age of 36.2 years. The most common cardiovascular risk factors were smoking (69.6%) and hyperlipidaemia (52%). One hundred and eighteen patients (53.4%) had previous myocardial infarction (MI). Triple vessel disease was present in 129 cases, double vessel disease in 59 cases and single vessel disease in 33 cases. Twenty three patients had significant left main coronary disease. The number of bypass grafts per patient averaged 2.3. The operative mortality was 2.07% (6 cases), death being due to myocardial infarction in 4 cases. Perioperative myocardial infarction was diagnosed in 12 cases (5.05%). One hundred and ninety nine patients were followed up for an average of 7.4 years. Seven of the 17 late fatalities were of cardiac origin. The actuarial 9 year survival rate was 84%. Five patients were reoperated after an average of 6.4 years. Eighty five per cent of patients were asymptomatic at the last follow-up examination. In conclusion, the symptoms of coronary artery disease in young adults can be effectively treated with a low operative risk by myocardial revascularisation surgery. Long-term follow-up remains essential to define the outcome in these patients. Systematic use of internal mammary artery bypass grafting should improve these results in the future.
