Cardiometabolic Effects of Empagliflozin in Patients Undergoing Elective Percu-taneous Coronary Intervention for Type 2 Diabetes Mellitus.

Aim      To evaluate cardiometabolic effects of empagliflozin in patients with ischemic heart disease and type 2 diabetes mellitus (DM) following elective percutaneous coronary intervention (PCI).Materials and methods Patients meeting the inclusion/non-inclusion criteria were randomized into two groups of equal number using simple randomization with successively assigned numbers. Group 1 included 37 patients (18 men and 19 women) who gave their consent for the treatment with empagliflozin 10 mg/day in addition to their previous hypoglycemic therapy. The drug administration started one month prior to the elective PCI and continued for the next 11 months (treatment duration, 12 months). Group 2 (comparison group) consisted of age- and DM duration-matched patients (37 patients; 18 men and 19 women) who continued on their hypoglycemic therapy previously prescribed by endocrinologists during the entire study period. Before the study, 36.11 % patients of the empagliflozin group and 27.03 % of the comparison group had unsatisfactory glycemic control as shown by the level of glycated hemoglobin (HbA1c).Results At 6 and 12 months of the study, fasting glycemia and HbA1c were significantly lower in the empagliflozin treatment group. The groups were comparable by the incidence of adverse outcomes: 8 (22.24 %) patients in the empagliflozin group and 10 (27.04 %) patients in the comparison group (р=0.787). The 12-month empagliflozin treatment reduced total cholesterol (C) by 5.56 % (p<0.05), low density lipoprotein (LDL) C by 3.67 % (p<0.05), visceral adipose tissue area (VATA) by 5.83 % (p<0.05), and subcutaneous adipose tissue area (SATA) by 3.54 % (p<0.05).Conclusion      The empagliflozin treatment for 30 days prior to and after elective PCI can enhance the effectiveness of myocardial revascularization due to the demonstrated beneficial cardiometabolic effects.

[Predictors of Coronary Plaque Vulnerability in Patients with Stable Coronary Artery Disease].

Aim      To identify new predictors for vulnerability of atherosclerotic coronary plaques in patients with stable ischemic heart disease (sIHD).Material and methods  This prospective, single-center study included 58 patients with sIHD. Unstable plaques were detected with virtual histology intravascular ultrasound of proximal and medium segments of a coronary artery without significant lesions according to coronarography data. Indexes of inflammation, dyslipidemia and carbohydrate metabolism were considered as candidate predictors for coronary plaque vulnerability.Results In 56 coronary arteries, 58 plaques were detected, 12 of which (20.7 %) were unstable. Vulnerable plaques differed morphologically from stable ones by a greater size of the necrotic core (35.1±8.5 % vs. 24.0±13.2 %; р=0.008), calcified nodules (2.0 [1.0; 5.0] % vs. 1.0 [0; 2.0] %; р=0.006), and a lower content of fibrous components (54.9±10.2 % vs. 66.4±15.8 %; р=0.02). In addition, vulnerable plaques more frequently narrowed the arterial lumen by >70 % of the lumen area (33.3 % vs. 2.2 %; р=0.0006). Correlation analysis showed a negative correlation between the level of high-density lipoproteins (HDL) and calcium volume (r= -0.4104; р=0.023); a positive correlation between the blood glucose level as determined by the oral glucose tolerance test and the lipid component (r=0.48198; р=0.033); and a negative correlation between the apolipoprotein A level and the calcium volume (r= -0.4297; р=0.008).Conclusion      The study demonstrated a high prevalence of vulnerable plaques in nontarget coronary arteries in patients with sIHD. In this process, dyslipidemia indexes (LDL, apolipoproteins A) correlate with the calcium volume whereas blood glucose, as measured in the oral glucose tolerance test, correlates with the lipid component of coronary plaque.

[Predictors of acute coronary syndrome in patients with ischaemic heart disease]. / Prediktory ostrogo koronarnogo sindroma u patsientov s ishemicheskoi bolezn'iu serdtsa.

Acute coronary syndrome has for a long time been giving no way of decreasing mortality related to ischaemic heart disease. The primary cause of acute coronary syndrome in the majority of cases is rupture of an unstable atherosclerotic plaque in the coronary artery followed by thrombosis thereof. The main missions of modern cardiology include: assessment of the risk of acute coronary syndrome, identification of predictors of adverse events, and working-out of measures aimed at prevention and optimal management of patients with ischaemic heart disease. This article deals with clinical and morphological factors associated with destabilization of coronary plaques, their rupture, and the development of an acute coronary event.

[Effect of empagliflosin on renal filtration in patients with coronary heart disease undergoing percutaneous coronary intervention].

Aim To evaluate the effect of empagliflozin on glycemia and renal filtration function in patients with stable ischemic heart disease (IHD) and type 2 diabetes mellitus (DM2) who underwent a percutaneous coronary intervention (PCI).Materials and methods This study included 40 patients with stable IHD and DM2 (age, 63 (58; 65) years; DM2 duration, 7 (4; 15) years) who had indications for an elective PCI. At baseline in the total sample, the level of glycated hemoglobin was 7.2 (6.5; 8.3)%; 48.7 % failed to achieve glycemic goals. A decrease in glomerular filtration rate (GFR) to below 60 ml/min/1.73 m2 was observed in 10.3 % of patients. All patients were divided into two group by simple randomization with successively assigned numbers. The main group consisted of 20 patients who received empagliflozin 10 mg/day in addition to their previous hypoglycemic therapy irrespective of their baseline glycemic control. Patients of the comparison group (n=20) continued on their previous hypoglycemic therapy as prescribed by their endocrinologist. The follow-up duration was 6 months. Statistical analysis was performed with the Statistica 10.0 software.Results The empagliflozin treatment improved the glycemic control; in the comparison group, no significant changes in glycemic control were observed. In both groups, GFR significantly decreased during the follow-up period; median decreases in GFR were -6.0 (-16.0; 4.0) and -8.4 (-26.5; 2.5) ml/min / 1.73 m2 in the main and comparison groups, respectively (p = 0.646). No significant changes in 24-h proteinuria were observed for patients taking empagliflozin. In the control group, the 24-h urinary protein excretion significantly progressed (p=0.011) during the follow-up period.Conclusion In patients with DM2 and stable IHD who underwent a PCI, addition of empagliflozin 10 mg/day to their current hypoglycemic therapy was associated with a significant improvement of glycemic control. The decrease in GFR during the empagliflozin treatment did not significantly differ from the value for patient receiving the other hypoglycemic therapy.

[Clinical Portrait of The Patient before the Planned Percutral Coronary Intervention in Conditions of Real Practice].

Aim To evaluate quality of treatment of patients with stable ischemic heart disease (IHD) prior to an elective percutaneous coronary intervention (PCI).Material and methods The study included 250 patients with stable IHD admitted for an elective PCI. Blood pressure, heart rate, total cholesterol, and blood glucose were measured for patients upon admission.Results Only 50 % of patients admitted to the clinic for elective PCI received optimal medical therapy (OMT); only 5.2 % of all patients achieved goal values of studied risk factors.Conclusion The study detected low compliance of stable IHD patients scheduled for PCI with OMT and achie-ve-ment of goal values for several risk factors.

[Vulnerable atherosclerotic plaques of coronary arteries in patients with stable coronary artery disease: 12-months follow-up].

RELEVANCE: A key objective of modern cardiology is the assessment of acute coronary syndrome (ACS) risk in patients with coronary artery disease (CAD) to develop preventive measures and choose optimal treatment strategies. OBJECTIVE: Detect vulnerable plaques of non-target coronary arteries in patients with stable CAD during routine percutaneous coronary intervention using virtual-histology intravascular ultrasound (VH-IVUS) and view their morphology over time. MATERIALS AND METHODS:  The prospective observational cohort study included 58 patients with stable CAD. After stenting of a target vessel, VH-IVUS was carried out in proximal and middle segments (6-8 cm) of a non-target coronary artery with no significant stenosis according to coronary angiography. Twelve months later, all patients underwent coronary angiography with re-IVUS of previously detected lesions. Death, myocardial infarction, rehospitalization, and unplanned myocardial revascularization due to vulnerable plaques were the endpoints of the study. RESULTS: IVUS with virtual histology revealed 58 lesions of non-target coronary arteries in 56 (96.5 %) patients. Two patients had no lesions in non-target coronary arteries. A large necrotic core with thin cap (thin-cap fibroatheroma) was detected in 12 (20.7 %) plaques, six of which had additional ACS risk criteria (stenosis area >70 % and / or lumen area <4 mm2). Within the 12­month follow-up period, three patients (one with a vulnerable plaque in IVUS) were hospitalized with a clinical picture of ACS. One cardiac death was registered in a patient with the IVUS vulnerable plaque. 7 of 12 vulnerable plaques stabilized in 12 months. CONCLUSION: 1) The data presented indicate a high rate (20.7 %) of vulnerable plaques of non-target coronary arteries in patients with stable CAD who underwent stenting; 2) Two (16.6 %) patients with vulnerable plaques reached endpoints (death and rehospitalization) within the 12­month follow-up period; 3) An analysis of atherosclerotic plaques in non-target coronary arteries over time showed that vulnerable plaques stabilized and did not cause ACS in more than half of cases (7 of 12); 4) Plaques that were not vulnerable according to IVUS were not likely to destabilize within the 12­month follow-up period.

[Outcomes of Various Revascularisation Strategies in the Elderly STEMI Patients With Multi-Vessel Coronary Pathology].

AIM: to assess safety and efficacy of single stage complete revascularization by multivessel stenting as primary percutaneous coronary intervention (pPCI) in elderly and middle aged patients with acute ST-elevation myocardial infarction (STEMI). MATERIAL AND METHODS: We included in this analysis data on 327 of 1690 STEMI patients who had undergone pPCI from 2009 to 2013. Age of 103 patients was more or equal 65 and of 224 less or equal 64 years. Multivessel stenting (MS) during pPCI was carried out in 26 and 65, while strategy of staged revascularization (SR) was implemented in 77 and 129 individuals among older and younger patients, respectively. During follow-up for 12 months we registered deaths, myocardial infarctions, and unplanned target vessel revascularizations. RESULTS: In each age group ( more or equal 65 and less or equal 64 years) there were no significant differences in clinical and demographic characteristics between subgroups of patients subjected to MS and SR. MS appeared to be safe and effective irrespective of age. Mortality during first 30-days was higher among patients aged more or equal 65 years. However, within each age group there were no significant differences in 1 year results between MS and SR subgroups.

[Results of endovascular revascularization in elderly patients with ST-segment elevation myocardial infarction in multivessel disease in relation to the degree of coronary atherosclerosis].

AIM: To investigate the impact of the degree of coronary atherosclerosis evaluated by the SYNTAX scale on the early and late results of endovascular revascularization in elderly and middle-aged patients with ST-segment elevation myocardial infarction (STEMI). SUBJECTS AND METHODS: The investigation enrolled 327 consecutively admitted patients with STEMI and multivessel coronary bed disease, who had received revascularization within the first 12 hours after disease onset via primary percutaneous coronary interventions (PCI). The clinical, demographic, and angiographic characteristics of the patients, as well as the specific features of chosen revascularization strategies and treatment outcomes were compared in two groups of 103 elderly patients (≥65 years of age) and 224 middle-aged patients (≤64 years) in relation to the severity of coronary bed lesion according to the SYNTAX scale. RESULTS: By and large, severe coronary atherosclerosis (≥23 SYNTAX scores) was related to reduced left ventricular ejection fraction and clinical manifestations of acute heart failure in all the analyzed patients regardless of their age and this was most markedly associated with the risk factors of cardiovascular events in the elderly patients. The elderly patients with severe coronary atherosclerosis (≥23 SYNTAX scores) were noted to have the lowest frequency of successful PCIs and higher 30-day mortality rates after primary PCI. CONCLUSION: The SYNTAX scale is of high prognostic value in the patients with STEMI, by determining the results of endovascular revascularization in elderly and middle-aged patients. The elderly patients with STEMI and severe coronary atherosclerosis are at very high risk for poor outcome within 30 days of follow-up after primary CPI, which necessitates a search for optimal revascularization strategies for this category of patients.

[In-hospital Outcomes and Complications of Percutaneous Coronary Interventions in Acute ST-Elevation Myocardial Infarction in Different Age Groups].

AIM: to assess early (in-hospital) results of percutaneous coronary intervention (PCI) for ST-elevation (STE) myocardial infarction (MI) in different age groups. MATERIALS AND METHODS: We enrolled in this study 356 patients with STEMI who underwent PCI within 24 hours of the disease during 1 year (2012). According to age all patients were divided into 2 groups: "young" ( less or equal 70 years) and "older" (>70 years). RESULTS: Compared with young in older group there were more patients with renal (53.84 vs. 19.78%) and myocardial (23.07 vs. 6.83%, =0.0000) dysfunction, hypertension (97.43 vs. 83.81% =0.0018), history of MI (19.23 vs. 10.43%, =0,3736), and acute heart failure at admission (32.04 vs. 13.95%, =0.0003), and less smokers (10.25 vs. 34.53%). Hospital mortality in older group was higher (8.97 vs. 1.43%, =0.0007) despite effective PCI. Rate of hemorrhagic complications (major bleedings+hemotransfusions) was also higher in older group (5.12 vs. 0.71%, =0.0077). CONCLUSION: Compared with younger older STEMI patients were characterized by more severe initial clinical condition and worse early results of primary PCI with higher mortality and rate of hemorrhagic complications. Thus the problem of improvement of management of this group of patients during hospitalization remains to be actual.
