Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
At the Cardio-Thoracic Clinic of the University hospital of Örebro has been developed a new method to harvest the saphenous vein together with the surrounding fat-tissue. This technique, called no-touch technique, has the advantage to reduce the damages to the vein during the harvesting, showing a substantially reduced risk for future occlusion (5% after 18 months and 10% after 8,5 years).
The aim of the PhD project is to evaluate the results of the no-touch technique in compare to the conventional technique for the venous graft harvesting. The focus of the study is to analyse all the operated patients in our clinic who underwent a post-operative coronary angiography do to angina pectoris (heart pain). All the patients who received a stent during the post-operative angiography will be analysed in detail and one will compare the occlusion grade and the rate of major adverse cardiac events (MACE).
This study is the first and the only one in the world that will examine the long-term results of the no-touch technique in particular after the stenting of the venous graft.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After the approval of the Regional ethical review board in Uppsala (Sweden), one could review all the subjects that received a PCI in a venous graft between January the 1st, 2006 and June the 30th, 2020 either at the Angiographic unit of the University Hospital of Orebro or at the Angiographic unit of the Hospital of Karlstad. All the participants has been previously operated at the Cardiothoracic department of the University hospital of Orebro with a coronary artery bypass grafting (CABG) procedure, with one type of vein graft (no-touch) or the other (standard) All the relevant data for the study that are missed in the quality register, are extrapolated by the clinical registers of the two hospital involved (Orebro and Karlstad).
Once finished the data extraction and review, the data will be statistically analysed in term of short and long term results; and an advanced comparison between the two different type of venous graft involved. This is to show if there is a significant difference between the two techniques also after a PCI procedure (already proven clinical different between the two technique in favour of the no-touch one by numerous studies).
Moreover an assessment of the patients´ quality of life in the two different studies will be performed with the use of Health related quality of life surveys (RAND-36); even a health economics analysis will be preformed (QALY).
