title: [Clinical behaviour after aorto-coronary vein bypass grafting related to the degree of revascularization (author's transl)].
abstract: The clinical behaviour after bypass-surgery was analysed with regard to anginal symptoms at rest and during daily exercise, working habits and postoperative medication in 135 patients, 3 to 28 months (average 18 months) postoperatively. All patients underwent postoperative coronary and left ventricular angiography, allowing a close correlation between postoperative clinics and patency-rate (average 84%) as well as the degree of revascularization (average 64%). 80% of the patients were clinically improved and, furthermore, there was a close correlation between the degree of improvement and revascularization. In contrast, only 42% of the patients were back to work and there was no correlation between the working habits and patency-rate or the degree of revascularization. Finally, postoperatively clearly improved patients showed a signif. smaller consumption of antianginal drugs, esp. nitrates.--This analysis of postoperative clinics and angiography suggests that improvement of symptoms through bypass-surgery is primarily due to the improvement of local perfusion in previously underperfused myocardial areas.
