Klinische und angiographische Akut- und Langzeitergebnisse nach direkter Stentimplantation bei Patienten mit symptomatischer koronarer Herzkrankheit

description: The study presented the acute- and long- time results of patients with coronary artery disease who undergo direct stent implantation. The values are resulted on one side from digital quantitative coronary coronarangiography (QCA) and on the other side from the clinical symptoms classified by the Canadian Cardiovascular Society (CCS) and the New York Heart Association (NYHA).Angiographic results:The proximal, mean and distal reference diameter did not vary between the various measurements. The minimal lumen diameter (MLD) increased from 0.8 (SD 0.4) mm up to 2.5 (SD 0.8) mm. This corresponds with an acute gain of 1.6 (SD 0.8) mm. At the follow-up was the value of MLD 1.6 (SD 0.8) mm, resulting a late loss of 0.5 (SD 0.9) mm. The net gain was 1.1 (SD 0.7) mm. The mean diameter of stenosis correlates similar to the MLD. The length of stenosis was quantified with 9.5 (SD 4.1) mm. The mean ballon diameter was 3.0 (SD 0.4) mm. The mean diameter of stenosis after intervention was calculated with 14%, after round about 6 months with 28%. In 46 cases (28%) a new stenosis in the stent area could be detected. In a group of 20 patients (43%) remained a restenosis (> 50% diameter of stenosis).Clinical results:Our patients had a lot of angiographic characteristics which come along with an increased risk of a worse outcome. Especially this relates to the high incidence of multivessel-disease and complex with partly thrombus containing stenosis (type B2 / C). Despite of this, the results from the digital quantitative coronarangiography and the clinical outcomes showed a very good angiographic and clinical output after direct stent implantation. 92% of the patients (n= 151) were significantly relieved of their symptoms and 1/3 was completely without any symptoms.The data analysis showed that the clinical outcomes of the patients differed often from the angiographic results of the therapied lesions.
