The Problem of Incomplete Myocardial Revascularization in Percutaneous Coronary Intervention in Patients With NSTEMI

Objective: to investigate the problem of incomplete myocardial revascularization in percutaneous coronary interventions in patients with acute coronary syndrome without St segment elevation who were admitted to the angiographic Department of the Sergiev Posad city hospital in the Moscow region.

The study will include all patients admitted to the intensive care unit of the regional hospital and sent to the angiographic Department for diagnosis and performance of PCI with acute coronary syndrome NSTEMI, including myocardial infarction (mi) and unstable angina, determined by clinical data, ECG signs and laboratory indicators. Anamnestic, clinical, biochemical indicators, cardiovascular risk factors, comorbid index that determines the course of acute coronary syndrome and prognosis (grace), a number of angiographic data, including the number of affected arteries and variants of the index "syntax score 50" and modified "syntax score 30", "syntax score 70" and" syntax score 90" to separate complete and incomplete revascularization, an integral indicator of the quality of the remaining index Syntex, the absolute value of which is corrected during data analysis. The data of patients living in the city of Sergiev Posad will be reviewed in such a way as to minimize the subsequent year of follow-up, using a telephone survey and the EMIAS electronic system

Inclusion criteria

• All patients who were referred to an angiographic unit with a diagnosis of NSTEMI for diagnostic coronary angiography and/or PCI from November 2018 to February 2019.

Exclusion criteria

• Patients with myocardial infarction with ECG- confirmed ST elevation of more than 1 mm in two leads.
• Residents of areas other than the area in question that may be difficult to contact.
