Abstract Background: The aim of this study was to investigate the correlation between serum biomarkers of left ventricular dysfunction and systemic inflammation in the first days after the acute episode, and to investigate their role for early identification of patients at high risk for post-infarction heart failure. Materials and methods: In total, 123 subjects admitted to the Intensive Cardiovascular Care Unit of the Cardiology Clinic of the Târgu Mureș County Clinical Emergency Hospital, Romania, with acute myocardial infarction were retrospectively analyzed in this study. Based on the level of NT-proBNP, the study population was divided into 2 groups: Group 1 (n = 92), with NT-proBNP <3,000 pg/mL, and Group 2 (n = 31), with NT-proBNP >3,000 pg/mL. Results: Biomarkers reflecting systemic inflammation presented significantly higher values in patients with elevated NT-proBNP (hs-CRP – 12.3 ± 8.9 mg/L vs. 3.6 ± 6.7 mg/L, p <0.0001, and interleukin 6 – 27.6 ± 30.7 pg/mL vs. 8.6 ± 6.2 pg/mL, p <0.0001). However, cell adhesion molecules VCAM and ICAM were not significantly different between the groups. Patients in Group 2 presented significantly higher rates of major cardiovascular events and rehospitalizations in the first year after the acute coronary event, with 13.33% event rate for patients in Group 2 compared to 8.7% in Group 1 (p <0.05). Conclusions: Serum biomarkers of ventricular dysfunction are strongly associated with systemic inflammation and ventricular impairment in the immediate phase after an acute myocardial infarction. Systemic inflammation has a higher impact on the clinical outcomes and progression to heart failure than the local coronary inflammation expressed by cell adhesion molecules.

Aim. To study the change in the -adrenergic reactivity of red blood cell membranes in patients during the first year after acute myocardial infarction. Materials and methods. The study included 25 patients with acute myocardial infarction (AMI) who signed informed consent to participate in the study. The erythrocyte membrane -adrenoreactivity index (-ARM) was determined in venous blood samples upon admission to the intensive care unit, one day after admission, 6 and 12 months after the index MI was transferred using the BETA-ARM-AGAT reagent kit (Agat-Med, Russia). Results. According to the results of dynamics assessment of -APM during the first day, patients included in the study were divided into 2 groups. Group 1 (n=14) included patients who had an increase in -APM in the first day, and group 2 (n=21) included patients in whom -ARM either did not change or decreased. At the time of admission to the hospital in the formed groups, there were no differences in the -APM index and clinical and anamnestic characteristics. A day after hospitalization, the value of -APM in group 1 significantly exceeded the same indicator in group 2 (p=0.02). At the periods of 6 and 12 months, the -APM indices in the groups did not differ. In the 2nd group of patients, the progression of chronic heart failure to one or more functional classes (NYHA) was significantly more often compared with the 1st group. Conclusion. The study showed that on the first day in patients with AMI, both an increase and a decrease in the activity of the sympathoadrenal system are possible with a further leveling of these differences over the next year. For a group of patients with decreased activity of sympathoadrenal system on the first day, a more unfavorable course of heart failure in the post-infarction period is characteristic.

Abstract Heart failure is a clinical syndrome that appears as a consequence of a structural disease, and the most common cause of left ventricular systolic dysfunction results from myocardial ischemia. Cardiac remodeling and neuroendocrine activation are the major compensatory mechanisms in heart failure. The main objective of the study is to identify the association between serum biomarkers illustrating the extent of myocardial necrosis (highly sensitive troponin as-says), left ventricular dysfunction (NT-proBNP), and systemic inflammatory response (illustrated via serum levels of hsCRP and interleukins) during the acute phase of a myocardial infarction, and the left ventricular remodeling process at 6 months following the acute event, quantified via speckle tracking echocardiography. The study will include 400 patients diagnosed with acute myocardial infarction without signs and symptoms of heart failure at the time of enrollment that will undergo a complex clinical examination and speckle tracking echocardiography. Serum samples from the peripheral blood will be collected in order to determine the inflammatory serum biomarkers. After 6 months, patients will be divided into 2 groups according to the development of ventricular remodeling, quantified by speckle tracking echocardiography: group 1 will consist of patients with a remodeling index lower than 15%, and group 2 will consist of patients with a remodeling index higher than 15%. All clinical and imaging data obtained at the baseline will be compared between these two groups in order to determine the features associated with a higher risk of deleterious ventricular remodeling and heart failure.

Background Full secondary prevention medication regimen is often under-prescribed after acute myocardial infarction. Design The purpose of this study was to analyse the relationship between prescription of appropriate secondary prevention treatment at discharge and long-term clinical outcomes according to risk level defined by the Thrombolysis In Myocardial Infarction (TIMI) Risk Score for Secondary Prevention (TRS-2P) after acute myocardial infarction. Methods We used data from the 2010 French Registry of Acute ST-Elevation or non-ST-elevation Myocardial Infarction (FAST-MI) registry, including 4169 consecutive acute myocardial infarction patients admitted to cardiac intensive care units in France. Level of risk was stratified in three groups using the TRS-2P score: group 1 (low-risk; TRS-2P=0/1); group 2 (intermediate-risk; TRS-2P=2); and group 3 (high-risk; TRS-2P≥3). Appropriate secondary prevention treatment was defined according to the latest guidelines (dual antiplatelet therapy and moderate/high dose statins for all; new-P2Y12 inhibitors, angiotensin-converting-enzyme inhibitor/angiotensin-receptor-blockers and beta-blockers as indicated). Results Prevalence of groups 1, 2 and 3 was 46%, 25% and 29% respectively. Appropriate secondary prevention treatment at discharge was used in 39.5%, 37% and 28% of each group, respectively. After multivariate adjustment, evidence-based treatments at discharge were associated with lower rates of major adverse cardiovascular events (death, re-myocardial infarction or stroke) at five years especially in high-risk patients: hazard ratio = 0.82 (95% confidence interval: 0.59–1.12, p = 0.21) in group 1, 0.74 (0.54–1.01; p = 0.06) in group 2, and 0.64 (0.52–0.79, p < 0.001) in group 3. Conclusions Use of appropriate secondary prevention treatment at discharge was inversely correlated with patient risk. The increased hazard related to lack of prescription of recommended medications was much larger in high-risk patients. Specific efforts should be directed at better prescription of recommended treatment, particularly in high-risk patients.
