    BACKGROUND Numerous studies have shown that coronary reperfusion with primary percutaneous coronary intervention (PCI) improves outcomes in patients with ST-segment elevated myocardial infarction (STEMI). However, the question of the effect on the myocardium as a whole of an isolated intervention on an infarct-related artery in multivessel coronary disease remains incompletely studied.AIM OF STUDY To study the features of perfusion redistribution and myocardial function using perfusion single photon emission computed tomography (SPECT) in patients with STEMI and multivessel coronary disease after isolated PCI on an infarct-related artery.MATERIAL AND METHODS SPECT-ECG (electrocardiography) was performed in 32 patients (27 men and 5 women) with STEMI. According to the ECG results, the location of focal myocardial changes was regarded as β€œlower” MI in 19 (59%) patients, β€œanterior” in 13 patients (41%). Coronary angiography revealed a multivessel lesion of the coronary vessels in all of them. The patients were divided into groups according to the location of the infarction and the area of the lesion: group 1 β€” lower MI (stenting of the right coronary artery (RCA) and its branches) β€” 19 patients (mean age β€” 57.7Β±2.5; median β€” 55 [51.5; 63.5]), of which 8 with small-focal (1a) and 11 with large-focal infarction (1b); group 2 β€” anterior MI (stenting of the left coronary artery (LCA) and its branches) β€” 13 patients (mean age β€” 55.4Β±3.5; median β€” 54 [48.5; 62.5]), of which 5 with small-focal (2a) and 8 with large-focal infarction (2b). SPECT-ECG was performed 3 times: 1st β€” on days 2–3 after PCI of the infarct-related artery, 2nd β€” 6 days after PCI, and 3rd β€” 6 months after PCI.RESULTS After RCA stenting in patients with lower MI and multivessel coronary disease, SPECT-ECG revealed a statistically significant decrease in local contractility of individual segments of the anterior septal and lateral walls (with sufficient revascularization of the RCA system) and worsening of perfusion and right ventricular (RV) volumes. After stenting of the LCA branches in patients with anterior MI and multivessel coronary disease, a statistically significant decrease in local contractility in the basal segment of the diaphragmatic wall was observed, as well as impaired perfusion and an increase in the volume of the RV (with successful revascularization of the anterior interventricular branch). All these findings could be the result of partial steal of the blood supply to neighboring areas and myocardial remodeling after PCI in patients with multivessel coronary artery disease.CONCLUSION 1. According to the data of single-photon emulsion computed tomography synchronized with electrocardiography in the early and late period of myocardial infarction after percutaneous coronary intervention in patients with multivessel coronary disease, there is a significant improvement in perfusion and function of the infarct-associated artery system. 1. Recanalization of only the left coronary artery with remaining stenoses in the right coronary artery in the long-term period can lead to an increase in the size of the cavity of the right ventricle of the heart and uneven distribution of perfusion in its The revealed statistically significant disturbances in perfusion and local contractility of neighboring areas after percutaneous coronary intervention of an infarct-related artery may be the result of steal of the blood supply and early myocardial remodeling in multivessel disease. 3. Disturbances in perfusion and local contractility in neighboring myocardial blood supply pools after percutaneous coronary intervention of an infarct-related artery dictates the need to repeated single-photon emulsion computed tomography synchronized with electrocardiography as early as possible in patients with multivessel coronary disease in order to assess the redistribution of perfusion and myocardial remodeling for timely complete revascularization, preventing recurrent coronaryΠΠšΠ’Π£ΠΠ›Π¬ΠΠžΠ‘Π’Π¬ ΠœΠ½ΠΎΠ³ΠΎΡ‡ΠΈΡΠ»Π΅Π½Π½Ρ‹Π΅ исслСдования ΠΏΠΎΠΊΠ°Π·Π°Π»ΠΈ, Ρ‡Ρ‚ΠΎ коронарная рСпСрфузия с ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½Ρ‹ΠΌ чрСскоТным ΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½Ρ‹ΠΌ Π²ΠΌΠ΅ΡˆΠ°Ρ‚Π΅Π»ΡŒΡΡ‚Π²ΠΎΠΌ (Π§ΠšΠ’) ΡƒΠ»ΡƒΡ‡ΡˆΠ°Π΅Ρ‚ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ лСчСния ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с острым ΠΈΠ½Ρ„Π°Ρ€ΠΊΡ‚ΠΎΠΌ ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄Π° (ОИМ) с подъСмом сСгмСнта ST.

    Aim. To determine the influence of the time gap between acute myocardial infarction with ST-segment elevation and intracoronary intervention performed later than 2.5 hours on myocardium, we studied indicators of perfusion over time with an aid of SPECT, including intraventricular asynchrony (2–4 days and 6–8 months after stent installation).Materials and method. We observed 22 patients with multivessel coronary lesion. The Russian program with the analysis of perfusion, function and the phase images was used in SPECT synchronized with ECG.Results. Showed that the time gap prior to coronary intervention in the acute phase of myocardial infarction may be directly connected with the increase in impaired perfusion during the end-systole and the severity of pathological intraventricular asynchrony without ECG signs. All patients had significantly decreased wall mobility and intraventricular asynchrony together with increased R-R interval in the late period (after 6–8 months) independently from the coronary intervention time. In patients of group 1 (coronary intervention within 6 hours), focal transmural lesions of myocardium significantly decreased.Conclusion. Late revascularization help decrease intraventricular asynchrony reducing the risk of heart failure in future.Β Π‘ Ρ†Π΅Π»ΡŒΡŽ опрСдСлСния влияния Π½Π° ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄ сроков ΠΎΡ‚ острого ΠΈΠ½Ρ„Π°Ρ€ΠΊΡ‚Π° ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄Π° с подъСмом сСгмСнта ST Π΄ΠΎ Π²Π½ΡƒΡ‚Ρ€ΠΈΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½ΠΎΠ³ΠΎ Π²ΠΌΠ΅ΡˆΠ°Ρ‚Π΅Π»ΡŒΡΡ‚Π²Π°, Π²Ρ‹ΠΏΠΎΠ»Π½Π΅Π½Π½ΠΎΠ³ΠΎ ΠΏΠΎΠ·Π΄Π½Π΅Π΅ 2,5 Ρ‡, с ΠΏΠΎΠΌΠΎΡ‰ΡŒΡŽ ΠΎΠ΄Π½ΠΎΡ„ΠΎΡ‚ΠΎΠ½Π½ΠΎΠΉ эмиссионной ΠΊΠΎΠΌΠΏΡŒΡŽΡ‚Π΅Ρ€Π½ΠΎΠΉ Ρ‚ΠΎΠΌΠΎΠ³Ρ€Π°Ρ„ΠΈΠΈ (ОЀЭКВ) Π² Π΄ΠΈΠ½Π°ΠΌΠΈΠΊΠ΅ (Π½Π° 2–4-Π΅ сут ΠΈ Ρ‡Π΅Ρ€Π΅Π· 6–8 мСс послС стСнтирования) ΠΈΠ·ΡƒΡ‡Π΅Π½Ρ‹ ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Ρ‹ ΠΏΠ΅Ρ€Ρ„ΡƒΠ·ΠΈΠΈ ΠΈ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ, Π² Ρ‚ΠΎΠΌ числС внутриТСлудочковая асинхрония.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π» ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.Β ΠžΠ±ΡΠ»Π΅Π΄ΠΎΠ²Π°Π½Ρ‹ 22 ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚Π° с многососудистым ΠΏΠΎΡ€Π°ΠΆΠ΅Π½ΠΈΠ΅ΠΌ ΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½ΠΎΠ³ΠΎ русла.

    The differentiation of the cases of the right ventricular failure in transplanted heart should be complex and challenging. The 28-year old man with dilated cardiomyopathy underwent orthotopic heart transplantation. After transplantation developed right ventricular failure. The biopsy (n = 5) didn’t reveal any signs of myocardial rejection. There were noted some signs of inflammation in lateral right ventricular wall only by gated SPECT. The right ventricular failure increased and 6 months later there was successfully performed the heart retransplantation on the patient. The virusological study revealed the Epstein–Barr virus in myocardium. The explanted heart research excluded limphoproliferative disease by immunogystochemical tests. The final diagnosis is myocarditis.Β Π”ΠΈΡ„Ρ„Π΅Ρ€Π΅Π½Ρ†ΠΈΡ€ΠΎΠ²Π°Π½ΠΈΠ΅ ΠΏΡ€ΠΈΡ‡ΠΈΠ½ ΠΏΡ€Π°Π²ΠΎΠΆΠ΅Π»ΡƒΠ΄ΠΎΡ‡ΠΊΠΎΠ²ΠΎΠΉ нСдостаточности пСрСсаТСнного сСрдца Π΄ΠΎΠ»ΠΆΠ½ΠΎ Π±Ρ‹Ρ‚ΡŒ комплСксным.

    On Some Problems of Trajectory Beam Program Control. Part II

    Get PDF
    The paper considers the problems of macroparameter control in a linear dynamic system. In the authors’ previous paper, such problems in controlling nonlinear systems were investigated. Variations of the considered functionals and necessary optimality conditions were obtained. This paper focuses on the trajectory beam control in the linear case. In this case, the problem of beam control can be reduced to the problem of the individual trajectory control. The developed approach may be of interest in the study of charged particle dynamics in accelerating and focusing structures, as well as in the construction of the velocity field in automatic image processing

    Use of a new Indis computer program to analyze the results of lacrimal scintigraphy

    Objective: to study the diagnostic importance of a new Indis software package for the postprocessing of the results of radionuclude examinations (Center for Information and Diagnostic Systems, St. Petersburg, Russia) when analyzing the results of lacrimal scintigraphy.Material and methods. Dynamic lacrimal scintigraphy was carried out in 6 volunteers (12 eyes) and 20 patients (32 years) with dacryostenosis. The examined Indis program and the known Syngo program (Siemens, Germany) were used to calculate the Β Β elimination half-life of a radiopharmaceutical from the interest region corresponding to the whole ocular surface. The time taken to postprocess the results of the Β examination was also determined.Results. When calculations were made using the Indis program and the Syngo system, the elimination half-lives of a tracer in the volunteers was 6.57Β±2.46 and 7.54Β±3.21 min, respectively. These in the patents with dacryostenosis were 69.39Β±65.52 and 74.85Β±64.59 min. With these programs, the times taken for postprocessing were 12.3Β±4.2 and 26.3Β±7.9 min, respectively

    WHAT CHANGES IN PERFUSION AND MYOCARDIAL FUNCTION AFTER LATE REVASCULARIZATION OF ACUTE MYOCARDIAL INFARCTION?

    Aim. To determine the influence of the time gap between acute myocardial infarction with ST-segment elevation and intracoronary intervention performed later than 2.5 hours on myocardium, we studied indicators of perfusion over time with an aid of SPECT, including intraventricular asynchrony (2–4 days and 6–8 months after stent installation).Materials and method. We observed 22 patients with multivessel coronary lesion. The Russian program with the analysis of perfusion, function and the phase images was used in SPECT synchronized with ECG.Results. Showed that the time gap prior to coronary intervention in the acute phase of myocardial infarction may be directly connected with the increase in impaired perfusion during the end-systole and the severity of pathological intraventricular asynchrony without ECG signs. All patients had significantly decreased wall mobility and intraventricular asynchrony together with increased R-R interval in the late period (after 6–8 months) independently from the coronary intervention time. In patients of group 1 (coronary intervention within 6 hours), focal transmural lesions of myocardium significantly decreased.Conclusion. Late revascularization help decrease intraventricular asynchrony reducing the risk of heart failure in future
