Despite implementation of antiproliferative drug-eluting stents (DES) and intention to perform maximally full myocardial revascularization during a single hospital stay even in acute coronary syndrome (ACS) the frequency of repeat interventions after endovascular revascularization remains at a sufficiently stable level.

In order to examine the causes of repeat hi-tech medical care rendered by means of endovascular myocardial revascularization for acute coronary syndrome without ST-segment elevation we carried out a retrospective single-centre study. It included a total of 93 patients suffering from ischaemic heart disease (IHD), who in 2017 endured this type of medical care twice.

The cases of repeat revascularization were analysed based on medical history taking, physical examination, ECG pattern, ultrasonographic examination, laboratory findings, data of electronic case report forms and video recordings of the previous and latest coronary angiographies (CAG).

The obtained findings revealed the main causes of repeat hi-tech medical care rendered within 1 year by means of endovascular myocardial revascularization for acute coronary syndrome without ST-segment elevation, which were as follows: progression of atherosclerosis in the previously non-revascularized arteries, the emergence of the clinical course of ACS in borderline stenosis; the development of acute coronary syndrome in patients with a significant lesion of the coronary bed, who were scheduled for this or that reason to undergo elective staged transcutaneous coronary intervention (TCI); restenosis in the previously implanted stents.

KEY WORDS: ischaemic heart disease, endovascular myocardial revascularization, hi-tech.
