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.

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.

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.

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.

Abstract   Left ventricular (LV) global function index (LVGFI) is a MRI marker of left ventricular remodeling. LVGFI has high predictive significance in young healthy individuals. The aim of the study was to assess prognostic significance in patients with acute coronary syndrome (ACS). We include into this analysis 2169 patients with ACS (1340 (61.8%) men and 829 (38.2%) women), mean age 64.08±12.601 years. All patients were observed in 2 Russian multicenter observational studies: ORACLE I (ObseRvation after Acute Coronary syndrome for deveLopment of trEatment options) (2004–2007 years) and ORACLE II (NCT04068909) (2014–2019 years). 1886 (87.0%) pts had arterial hypertension, 1539 (71.0%) – history of coronary artery disease, 647 (29.8%) – history of myocardial infarction, 444 (20.5%) - diabetes mellitus. Duration of the follow-up was 1 years after the hospital discharge. Cases of death from any cause, coronary deaths, repeated coronary events (fatal and non-fatal) were recorded. An echocardiographic study was conducted 5–7 days from the time of hospitalization. The LVGFI was defined as LV stroke volume/LV global volume × 100, where LV global volume was the sum of the LV mean cavity volume ((LV end-diastolic volume + LV end-systolic volume)/2) and myocardial volume (LV mass/density). During the follow-up, 193 deaths were recorded (8.9%), 122 deaths (5.6%) were coronary. In total, repeated coronary events were recorded in 253 (11.7%) patients. Mean LVGFI was 22.64±8.121%. Patients who died during the follow-up were older (73.03±10.936 years and 63.15±12.429 years, p=0.001), had a higher blood glucose level at the admission to the hospital (8.12±3.887 mmol/L and 7.17±3.355 mmol/L, p=0.041), serum creatinine (110.86±53.954 μmol/L and 99.25±30.273 μmol/L, p=0.007), maximum systolic blood pressure (196.3±25.17 mm Hg and 190.3±27.83 mm Hg, p=0.042). Those who died had a lower LVGFI value (19.75±6.77% and 23.01±8.243%, p&lt;0.001). Myocardial mass index, ejection fraction and other left ventricular parameters did not significantly differ between died and alive patients. Among the patients who died, there were higher rate of women, pts with a history of myocardial infarction, heart failure, diabetes. In a multivariate analysis, diabetes mellitus OR1.67 95% CI [1.12–2.51] p=0.012, history of heart failure (1.78 [1.2.-2.59], p=0.003), a history of myocardial infarction (1.47 [1.05–2.05], p=0024), age (1.06 [1.05–1.08], p=0.001) and LVGFI &lt;22% (1.53 [1.08–2.17], p=0.015) were independent predictors of death from any cause. The LVGFI was also independently associated with the risk of coronary death, but not with the risk of all recurring coronary events. Thus, LVGFI may be useful the marker to assess risk in patients who have experienced an ACS episode. Funding Acknowledgement Type of funding source: None

Purpose. The study aims to determine the impact of dysthyroidism on the severity and type of coronary lesion, on vascular function, as well as on the morbidity and mortality of patients with acute coronary syndrome, by finding predictive markers that can be translated into preventive measures that contribute substantially to reduce the number of newly diagnosed patients with coronary heart disease. Methods. We introduced in the study 100 patients recently diagnosed with acute coronary syndrome, without history of ischemic heart disease or thyroid disease, hospitalized in the Cardiology Clinic of the “Bagdasar-Arseni“ Emergency Clinical Hospital Bucharest, for the interventional treatment of acute coronary syndrome. The studied patients were hospitalized between November 2014 and April 2015, with regular follow-up of up to 5 years (telephone or direct interview, conducted at 6 months, 12 months, 24 months, 36 months, 48 months, 60 months), with an average period follow-up of 1006 days, evaluated clinically, bio-humorally, by echocardiography, explored with coronary angiography with the calculation of the SYNTAX score and with the performance of electrocardiogram and pulse wave. The obtained data were integrated in Excel sheets and statistically processed with the Python program. Results. The mortality rate in the patient group was 7% (7 deaths). Descriptively, of the deceased, 6 patients (86%) were male, and as thyroid status 1 hyperthyroid patient (14%), 3 hypothyroid patients (43%) and 3 patients (43%) normothyroid. There were 4 deaths (8%) in the group of patients with unstable angina and 3 deaths (8%) in the group of patients with myocardial infarction without ST-segment elevation. There were no deaths in the group of patients with acute myocardial infarction with ST-segment elevation. At follow-up, 41 patients (41%) were readmitted. Re-hospitalization was influenced by elevated values of mean blood pressure, diastolic blood pressure and C-reactive protein, unicoronary atherosclerotic disease and unstable angina at admission. At follow-up, the development of noncardiac events was noted in the evolution of patients, diabetes mellitus occurring in the majority, in almost a quarter of patients (22 patients, respectively 24% developed diabetes over time), 34% (19 patients) in euthyroidism and 8% (3 patients) dysthyroidism. Discussions. Predictive factors for the readmission of the patient with acute coronary syndrome are highlighted the following: increased level of C-reactive protein (p = 0.017), tricoronary vascular damage (p = 0.01), diastolic blood pressure greater than 80 mmHg (p = 0.025), and euthyroid status (p = 0.04). The probability of death for the patient with acute coronary syndrome rises to 66% in the presence of severe systolic dysfunction of the left ventricle (p = 0.006), and to 61% in the case of elevated values of hs troponin I (p = 0.008). In our study, the presence of dysthyroidism in the patient with acute coronary syndrome has a protective role in the development of diabetes in the first 5 years (p = 0.025). Conclusion. Dysthyroidism is associated with increased morbidity and mortality from cardiovascular disease.

Aim. To assess the long-term results of different approaches to treating patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) and multivessel coronary artery disease (MVCAD). Subjects and methods. A total of 150 patients with NSTE ACS, in whom coronary angiography revealed MVCAD, were examined. The patients were divided into 3 groups according to the selected treatment policy: 1) percutaneous coronary intervention (PCI) (n=91 (60.6%)); 2) coronary artery bypass grafting (CABG) (n=40 (26.6%)); and 3) only medical treatment (n=9 (6%)). The mean follow-up was 27.6±3.5 months. Results. The medical treatment policy in this patient sample demonstrates the worst results, with the majority of cardiovascular events developing in the hospital period. PCI in patients with NSTE ACS and multiple coronary atherosclerosis has a number of objective limitations in this patient sample, leading to suboptimal treatment outcomes Conclusion. The use of CABG or PCI as a myocardial revascularization technique in patients with NSTE ACS and MVCAD is characterized by a comparable satisfactory survival in the hospital and long-term follow-up periods. 12% of patients do not receive revascularization due to the extremely high risk from any of coronary blood restoring methods, which results in very many deaths largely occurring during the hospital period.
