Aim To study a relationship of several factors (clinical and genetical markers) with unfavorable outcomes in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in long-term follow-up.Material and methods This full-design, prospective study included 415 patients with NSTE-ACS. 266 patients were evaluated for the presence of multifocal atherosclerosis (MFA). Typing of polymorphic variants rs1041981 LTA, rs1800629 TNF, rs4986790, and rs498679 TLR4, and also rs3024491 and rs1800872 IL10 was performed. Follow-up period lasted for 67±4 months. By the end of this period, information about clinical outcomes for 396 patients became available.Results During the entire follow-up period, unfavorable outcomes were observed in 239 (57.5 %) patients with NSTE-ACS. The following clinical signs were associated with unfavorable outcomes: history of myocardial infarction, age >56 years, left ventricular ejection fraction (LV EF) ≤50 % and GRACE score ≥100, significant stenosis of brachiocephalic arteries, MFA, carriage of genotype А / А rs1041981 LTA (OR, 6.1; р=0.02) and allele А (OR, 1.9; р=0.01). According to results of a multifactorial analysis, the most significant predictors included LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.Conclusion Stratification of patients with NSTE-ACS into groups of high or low risk for having an unfavorable outcome within the next 6 years is possible using the prognostic model developed and presented in this study. The model includes the following signs: LV EF <50 %, MFA, and carriage of genotype А / А rs1041981 LTA.

Aim: Identification of predictors of unfavorable annual prognosis in patients with acute coronary syndrome with ST-segment elevation (STEMI). Material and methods: The study included 69 patients with STEMI who were hospitalized in the period from March 2014 to January 2017 in the hospital named after Zhadkevich. The follow-up period was 12±3 months after the index STEMI Longterm prognosis was established in 62 (89.8%) patients. Results: the fatal outcome was observed in 7 (11.3%) patients. Nonfatal myocardial infarction developed in 10 (16.2%), hospitalization with heart failure decompensation - in 5 (8%), nonfatal acute cerebrovascular accident - in 3 (4.8%) patients. Predictors of adverse prognosis were: age >60 years, level of brain natriuretic peptide (BNP) >29.2 pmol/l, C-reactive protein (CRP) >4.7 mg/l, left ventricular ejection fraction (LVF) 60 years and BNP level >29.2 pmol/l. Conclusion: Adverse factors affecting the long-term outcome of the disease (12±3 months after the STEMI) are: BNP level >29.2 pmol/l, CRP level >4.7 mg/l, LV FV value 60 years.

Thromboembolic events are a common complication in Takotsubo syndrome (TTS). However, their long-term incidence compared with acute coronary syndrome (ACS) is lacking. In-hospital and long-term incidence of thromboembolic events of 138 consecutive patients with TTS were compared with 138 sex- and age-matched patients with ACS. Predictors of events were analyzed. The incidence of thromboembolic events in TTS was 2-fold higher than ACS (21% vs 9%; P < .01) over a mean follow-up of 5 years. Although the left ventricular ejection fraction (LVEF) at event was significantly lower in TTS compared with ACS (38% [9%] vs 54% [11%]; P < .01), the follow-up LVEF was comparable. Patients with TTS suffering from thromboembolic events were more often treated with anticoagulation compared with ACS (44.8% vs 8.3%, P = .03). However, more patients presenting with ACS (100% vs 48.3%; P < .01) were discharged on aspirin. Only elevated C-reactive protein was a predictor of thromboembolic events using multivariate analysis (hazard ratio 1.1, 95% confidence interval, 1.0-1.2; P < .01). In conclusion, the risk of thromboembolic events in TTS was significantly higher than the risk of thromboembolic events in ACS over a mean follow-up of 5 years.

The aim. To study the risk factors for hospital mortality in patients with acute coronary syndrome with ST-segment elevation (STEACS) complicated by cardiogenic shock (CS).Materials and methods. A total of 104 patients with STEACS complicated by CS were studied. The follow-up group (group I) included 58 (55,8%) patients who died in hospital (mean age 71,8±7,31 years), the comparison group (group II) – 46 patients, who have been treated and discharged (mean age 59,5±6,18 years). All patients underwent general clinical studies, the level of troponins, lipids, glucose, creatinine in plasma was determined, electrocardiography and echocardiography were performed. Coronary angiography and percutaneous coronary intervention (PCI) were urgently performed. The method of binary logistic regression with the determination of the odds ratio and its 95% confidence interval for each reliable variable was used to identify risk factors for hospital mortality.Results. In group I patients with CS, compared with group II, patients over the age of 70 (32 (55,2%) vs 10 (22,7%), р=0,0004), with concomitant chronic kidney disease (32 (55,2%) vs 9 (19,6%), p=0,0002), postinfarction cardiosclerosis (30 (51,7%) vs 9 (19,6%), р=0,001) and chronic heart failure of III-IV functional class (32 (55,1%) vs 11 (23,9%), p=0,001) were significantly more often observed. Baseline levels of plasma leukocytes, troponin and creatinine were significantly higher in deceased patients with CS. Left ventricular ejection fraction below 40% was observed more often in the follow-up group than in the comparison group (46 (79,3%) vs 27 (58,7%), p=0,022). In group I, compared with group II, there was a higher incidence of three-vessel coronary lesions (36 (75%) vs 12 (26,1%), p=0,0001) and chronic coronary artery occlusion unrelated to STEACS (25 (52,1%) vs 12 (26,1%), р=0,009). The same trend was observed when assessing the average number of stenoses and occlusions of the coronary arteries. PCI was performed in 43 (74,1%) of the deceased and 43 (93,5%) of the surviving STEACS patients with CS (p=0,009). The follow-up group had a higher rate of unsuccessful PCI (30,2%) vs 3 (7%), р=0,001) and performed later than 6 hours after the onset of an angina attack (28 (65,1%) vs 6 (14%), р=0,0001).Summary. Hospital mortality in patients with STEMI complicated by CS was associated with the presence left ventricular ejection fraction less than 40%, three-vessel coronary lesion and performing PCI later than 6 hours from the beginning of the pain attack.

Introduction: Left bundle branch pacing (LBBP) is a novel pacing method and has been proven to have low and stable pacing thresholds. However, data on large numbers of patients with long-term follow-up is still needed to evaluate its feasibility and safety. Hypothesis: To evaluate the feasibility and safety of LBBP in a large sample with long-term follow up. Methods: This study prospectively enrolled 632 consecutive patients with left bundle branch block, AV block or sick sinus syndrome with attempted LBBP from April 2017 to July 2019. Pacing parameters, ECG, echocardiographic measurements, complications were assessed at implant, and during follow-up of 1, 6, 12 and 24 months. Results: LBBP was successful in 618/632 (97.8%) patients according to the strict criteria for LBB capture. Mean follow-up time was 17.8±6.9 months. LBB capture threshold at implant was 0.65±0.27 [email protected] and 0.71±0.35 [email protected] at 2-year follow-up (n=166). Left ventricular ejection fraction were improved in QRS≥120ms and <120ms groups (60.62±14.22% vs. 63.95±11.29 %, p<0.001; 49.77±17.58 % vs. 58.58±12.79 %, p<0.001; respectively). The number of patients with moderate and sever tricuspid regurgitation decreased at 1-year (120 to 66;28 to 16; respectively). Permanent right bundle branch injury occurred in 55 (8.9%) patients. LBB capture threshold increased greater than 2 V in 6 patients, loss of capture in 2 patients, two lead dislodgements requiring operative revision within 1 month after implantation during 2-years follow-up. Conclusions: Feasibility and safety of LBBP were confirmed by this large sample size and long-term follow-up study. It is a reliable physiologic method for standards pacing indications.

Abstract Aims Several studies have shown that Takotsubo syndrome (TTS) secondary to neurological disorders is associated with higher rate of in-hospital complications. Imaging brain studies found that atrophy or damage of some regions and their altered connectivity with other brain regions are typical features of TTS patients. The aim of the study is to evaluate rates of in hospital and long-term Follow-up events in TTS patients with history or acute cerebrovascular events (CVE). Methods and results 395 consecutive patients were enrolled in a multicentre prospective registry. History, clinical data, echocardiographic parameters and in-hospital and long-term follow-up events of all patients were evaluated. Prevalence of cerebrovascular events among TTS patients was 9.4% (num = 37). Compared to the control group, these patients were older (80 ± 7 vs. 71 ± 12, P = 0.01) and predominantly men (24% vs. 9%, P = 0.01). No differences in term of cardiovascular risk factors and left ventricular ejection fraction at admission and discharge were found among the two groups. The prevalence of physical stressor was higher in the CVE group (67% vs. 44% P = 0.01). The incidence of in-hospital adverse events was higher in the CVE than in the control one (70% vs. 29%), mainly driven by higher rate of Cardiogenic shock (19 vs. 8% P = 0.01) and in-hospital death (19 vs. 4%, P = 0.01). At long-term follow-up, patients in CVE group hat higher mortality rate (38% vs. 20% P = 0.01)). Patients presenting with acute CVE, 10 out of 37 patients (27%) when compared with chronic CVE had higher in-hospital mortality (40% vs. 11% P = 0.01). Conclusions TTS patients with history or acute cerebrovascular events had higher rate of in-hospital events and death at long-term follow-up. Acute cerebrovascular events in the setting of TTS are featured with worst prognosis.
