Introduction: In non-ST-segment elevation acute coronary syndrome (NSTE-ACS), ST-elevation in lead aVR (ST↑aVR) on admission ECG has been shown to be associated with severe coronary artery disease, but its impact on long-term clinical outcomes is unclear. Methods: We studied 454 patients with NSTE-ACS who underwent coronary angiography during initial hospitalization. Patients were divided into the 3 groups according to the degree of ST↑aVR on admission ECG: no ST↑aVR (n=301, G-A); ST↑aVR <1.0 mm (n=82, G-B); and ST↑aVR ≥1.0 mm (n=71, G-C). Troponin T (TnT), hemoglobin (Hb), estimated glomerular filtration rate (eGFR), brain natriuretic peptide (BNP), high-sensitivity C-reactive protein (hsCRP), TIMI risk score, and summed ST-segment depression in other leads were also measured on admission. Results: There were no differences in sex or coronary risk factors except for diabetes mellitus in the 3 groups. In G-A, G-B, and G-C, age was 66±11, 68±11, and 70±11 years; the rates of diabetes mellitus were 30%, 48%, and 51%; Killip class ≥2 was 7%, 20%, and 34%; positive TnT was 30%, 46%, and 56%; TIMI risk score was 2.8±1.4, 3.6±1.3, and 3.8±1.2; the levels of Hb were 13.4±1.9, 13.2±1.9, and 12.2±2.3 g/dl; eGFR was 65±24, 59±27, and 53±28 ml/min/1.73 m2; BNP was 155±249, 386±338, and 455±507 pg/ml; hsCRP was 0.339±1.499, 0.654±1.899, and 0.842±1.788 mg/dl; summed ST-segment depression was 2.0±2.6, 5.6±3.5, and 13.0±6.6 mm; the rates of left main or 3-vessel disease were 9%, 44%, and 75%; and major adverse events (death, [re]infarction, urgent revascularization, or heart failure requiring hospitalization) at 5 years were 19%, 43%, and 58%, respectively (all p<0.01). After adjusting for baseline characteristics, multivariate analysis showed that as compared with no ST↑aVR, the hazard ratios (95% CI) for 5-year adverse events associated with ST↑aVR <1.0 mm and ST↑aVR ≥1.0 mm were 2.16 (1.10-5.59; p=0.019) and 3.90 (1.44-9.76; p=0.001), respectively. Conclusions: In patients with NSTE-ACS, greater ST↑aVR on admission ECG strongly predicted 5-year adverse outcomes, even after adjusting for traditional risk factors, biomarker profiles, and ST-segment depression in other leads. Our findings suggest the importance of ST↑aVR in risk stratification for NSTE-ACS.

Background: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI ) are common types of acute coronary syndrome which are associated with the risk factors of age, obesity, hypertension, and diabetes. Objective: The present study aimed to examine the effects of age on the risk factors and clinical symptoms of acute coronary syndrome. Methods: A cross-section prospective study was conducted on 125 patients with acute coronary syndrome chosen by non-probability convenience sampling method in the coronary care unit in Sulaimani, the Kurdistan region of Iraq. Acute coronary syndrome types were diagnosed through clinical presentations, electrocardiography (ECG), and troponin test. Data was collected using a researcherbased checklist through face-to-face interviews. Results: The results indicated that males were the dominant group. The age group 45-65 had the highest prevalence rate of acute coronary syndrome. The most frequent risk factors for acute coronary syndrome were hypertension (54.4%), dyslipidemia (52%), smoking (42.4%), and diabetes mellitus (38.4%). Typical chest pain was found to be the most frequent clinical presentation (88%). There was a significant difference between the age groups in terms of the effect of age on typical and atypical symptoms; however, neither age nor typical/atypical symptoms had a significant effect on type of acute coronary syndrome. Similarly, family history, hypertension, diabetes mellitus, obesity, smoking, physical inactivity, and dyslipidemia had no effect on type of acute coronary syndrome. Conclusion: Age is a predictive factor for acute coronary syndrome, but family history, hypertension, diabetes mellitus, obesity, smoking, physical inactivity, and dyslipidemia cannot predict acute coronary syndrome.

Objective: to study the risk factors for acute renal injury, the dynamics of renal function and prognosis in patients with acute coronary syndrome with ST-segment elevation (STEACS) with contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (PCI).Materials and methods. We studied 20 patients with STEACS, who developed СIN after PCI (follow-up group), and 98 patients with STEACS without СIN (comparison group). All patients were measured plasma creatinine level and glomerular filtration rate by the formula CKD-EPI before and 48 hours after PCI. CIN was detected with an increase in creatinine levels in the blood by more than 26.5 µmol / l from the baseline 48 hours after administration of radiopaque drug (RCP). Endpoints were evaluated at the hospital stage and within 12 months after PCI.Results. CIN after PCI occurred in 16.9 % of patients with STEACS. Among patients with СIN, persons aged over 75 years (60 %), with diabetes mellitus (45 %), chronic kidney disease (75 %), postinfarction cardiosclerosis (50 %), chronic heart failure of functional class III–IV (80 %), developed acute heart failure T. Killip III–IV (90 %) were significantly more often observed. The left ventricular ejection fraction was lower in patients with СIN (p <0.05). The average increase in plasma creatinine 48 hours after PCI was higher in the follow-up group (p <0.05). In patients with СIN more often, than without СIN, three-vascular lesions of the coronary bed were detected (65 and 25.5 % respectively, p <0.001). The same trend was observed, when assessing the average number of coronary artery stenoses, the number of implanted stents and the volume of RCP used. Patients with СIN, than without СIN, were longer in hospital (12.1 ± 0.96 and 10.2 ± 1.11 days respectively, p <0.05) and more often needed re-hospitalization within 12 months after PCI (34 and 4.1 % respectively, p <0.05).Summary. CIN in patients with STEACS after primary PCI was more likely to develop, if the following symptoms were present: age over 75 years, diabetes mellitus, chronic heart failure, post-infarction cardiosclerosis, chronic kidney disease, low ejection fraction of the left ventricle, initially high creatinine level, development of acute heart failure, trisovascular coronary lesion and multiple coronary stenting. The duration of hospital stay and the frequency of re-hospitalizations within a year after PCI significantly increased in patients in the CIN group.

The original article tells about the key aspects that characterize the problem of acute coronary syndrome without ST-segment elevation (ACSWSTE) in the Russian Federation: high prevalence, current approaches to risk assessment of early and long-term adverse outcomes and diagnostic challenges. Based on the data from the All-Russian Register RECORD-3, the main factors limiting the effectiveness of treatment of patients with ACSWSTE are highlighted: underestimated relevance of risk calculators (GRACE) and biological markers for myocardial necrosis by practicing physicians who manage these patients, underutilization of invasive treatment, failure to prescribe drugs that improve prognosis, including dual antiplatelet therapy in patients with conservative management. The prospects for the use of ticagrelor (Brilinta) to improve short- and long-term prognosis of the disease are estimated.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.
