: In this review, we will explore the role of PCSK9 and inhibition of PCSK9 in patients after acute myocardial infarction (MI). Despite the implementation of evidence-based therapies to improve outcomes, mortality at one-year remains at 12-15% and the need to further reduce complications related to MI persists. Mechanistic and epidemiologic studies suggest that the naturally occurring PCSK9 protein increases coronary plaque vulnerability through several pathways, including pro-inflammatory LDL-C oxidation and direct modification of plaque composition. PCSK9 inhibitors are a class of drugs with proven efficacy in patients with recent MI. The latest guidelines recommend the use of PCSK9 in patients with recent MI early in the process of care to reduce LDL-C values and associated morbidity. The use of PCSK9 inhibition could be beneficial for mortality reduction after an acute MI and should be tested in an appropriately powered randomized controlled trial.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): National Health Fund Background. A novel comprehensive care program after acute myocardial infarction (AMI) „KOS-zawał" was implemented in Poland. It includes acute intervention, complex revascularization, implantation of cardiovascular electronic devices (in case of indications), rehabilitation or hybrid telerehabilitation (HTR) and scheduled outpatient follow-up. HTR is a unique component of this program. The purpose of the pilot study was to evaluate a feasibility, safety and patients’ acceptance of HTR as component of a novel care program after AMI and to assess mortality in a one-year follow-up. Methods The study included 55 patients (LVEF 55.6 ± 6.8%; aged 57.5 ± 10.5 years). Patients underwent a 5-week HTR based on Nordic walking, consisting of an initial stage (1 week) conducted within an outpatient center and a basic stage (4-week) home-based telerehabilitation five times weekly. HTR was telemonitored with a device adjusted to register electrocardiogram (ECG) recording and to transmit data via mobile phone network to the monitoring center. The moments of automatic ECG registration were pre-set and coordinated with exercise training. The influence on physical capacity was assessed by comparing changes in functional capacity (METs) from the beginning and the end of HTR. Patients filled in a questionnaire in order to assess their acceptance of HTR at the end of telerehabilitation. Results HTR resulted in a significant improvement in functional capacity and workload duration in exercise test (Table). Safety: there were neither deaths nor adverse events during HTR. Patients accepted HTR, including the need for interactive everyday collaboration with the monitoring center. Prognosis all patients survived in a one-year follow-up. Conclusions Hybrid telerehabilitation is a feasible, safe form of rehabilitation, well accepted by patients. There were no deaths in a one-year follow-up.

Aim. This study was designed to evaluate the relationship between microRNAs (miRNAs), miR-126-3p and miR-223-3p, as new biomarkers of platelet activation, and predicting recurrent thrombotic events after acute myocardial infarction (AMI). Methods and Results. The analysis included 598 patients randomized in the PRAGUE-18 study (ticagrelor vs. prasugrel in AMI). The measurements of miRNAs were performed by using a novel miRNA immunoassay method. The association of miRNAs with the occurrence of the ischemic endpoint (EP) (cardiovascular death, nonfatal MI, or stroke) and bleeding were analyzed. The miR-223-3p level was significantly related to an increased risk of occurrence of the ischemic EP within 30 days (odds ratio (OR) = 15.74, 95% confidence interval (CI): 2.07–119.93, p = 0.008) and one year (OR = 3.18, 95% CI: 1.40–7.19, p = 0.006), respectively. The miR-126-3p to miR-223-3p ratio was related to a decreased risk of occurrence of EP within 30 days (OR = 0.14, 95% CI: 0.03–0.61, p = 0.009) and one year (OR = 0.37, 95% CI: 0.17–0.82, p = 0.014), respectively. MiRNAs were identified as independent predictors of EP even after adjustment for confounding clinical predictors. Adding miR-223-3p and miR-126-3p to miR-223-3p ratios as predictors into the model calculating the ischemic risk significantly increased the predictive accuracy for combined ischemic EP within one year more than using only clinical ischemic risk parameters. No associations between miRNAs and bleeding complications were identified. Conclusion. The miR-223-3p and the miR-126-3p are promising independent predictors of thrombotic events and can be used for ischemic risk stratification after AMI.

Abstract Background Mortality following acute myocardial infarction (MI) remains high despite progress in pharmacotherapy and interventional treatment. In 2017 a nation-wide system of managed care for MI survivors comprising a continuum of acute treatment of MI, staged revascularization, cardiac rehabilitation, cardiac electrotherapy and cardiac ambulatory care within one year following MI was implemented in Poland. The managed care programme (MCP) includes also the quality of care assessment based on clinical measures (e.g. cardiovascular risk factors control) as well as on the rate of minor and major cardiovascular events. The goal of the analysis was to assess the overall mortality of MI survivors participating and not participating in the MCP. Methods The database of survivors of acute MI discharged from hospital from October 1, 2017 to December 31, 2018 was analyzed. Patients who died within 10 days after discharge were excluded from the analysis. The primary end-point was defined as death from any cause. Propensity-Score Matching (PSM) using nearest neighbor matching was used to form comparable groups of patients participating and not participating in the MCP. The Cox proportional hazard regression analysis was used to assess the relation between MCP and the overall mortality. Results MCP was implemented in the first stage in 48 hospitals spread around the country (about 34% of all hospitals treating acute MI patients in Poland). Out of 87739 analyzed patients (age: 68.1±11.9 years; 55581 men and 32158 women) 34064 were hospitalized in hospitals with MCP implemented. Altogether 10404 patients (11.9% of the whole cohort; 30.5% of those hospitalized in hospitals with MCP implemented) participated in MCP. They were matched with 10404 patients not participating in the MCP. During 324.8±140.5 days of follow-up 7413 patients died. One-year mortality was lower in patients participating in the MCP both when we analyzed the whole cohort (4.4% vs. 9.5%; p<0.001) as well as when we limited the analysis to the PSM groups (4.4% vs. 6.5%; p<0.001, figure 1). MCP was related to the overall mortality in univariate (HR 0.43 [0.39–0.48]) as well as in multivariate analysis (0.64 [0.57–0.71]) in the whole cohort as well as in the PSM cohort (HR 0.63 [0.56–0.72] and 0.64 [0.56–0.72] for the univariate and multivariate analysis respectively). When we limited the analysis to hospitals in which MCP was implemented one-year mortality was 4.3% vs. 6.3% (p<0.001) whereas univariate HR was 0.51 (0.44–0.60) and multivariate HR 0.52 (0.44–0.61). Conclusion The implemented in Poland nation-wide system of managed care for MI survivors is related to improved survival. Therefore, the Ministry of Health plans to implement the programme in all cardiac centers in Poland. Funding Acknowledgement Type of funding source: None

Abstract Background Malignant arrhythmias, ventricular tachycardia or ventricular fibrillation (VT/VF) in acute myocardial infarction (AIM) carry ominous prognosis including sudden cardiac death (SCD). It is not clear whether the timing of VT/VF occurrence always affects the poor prognosis of patients with AMI. Aim To investigate the prognosis of patients who undergoing primary percutaneous coronary intervention (PCI) in accordance with timing of VT/VF and to find the power predictors of their occurrence. Methods 307 consecutive patients in PREDICT-VT study (NCT03263949), 57.9±10.6 year old, 72.3% males were analysed. Of these patients, 27.7% had VT/VF from the symptoms onset, within 48 hours of AIM (early VT/VF group). 8.1% of patients had VT/VF after 48h, during one year follow up (late VT/VF group). Results The frequency of VT/VF occurrence was high between symptoms onset and the end of 2nd month and during 5th and 6th month of AIM. The parameters of conventional echocardiography were significantly impaired in late VT/VF group, as well as parameters of longitudinal strain (LS) (table). Moreover, the MACE (cardiovascular mortality, SCD, new infarction, emergency revascularisation, and hospitalized heart failure) was the highest in late VT/VF group (p=0.000). The most significant predictor of late VT/VF was systolic LS (cut off −12.72%, ROC 0.680, Sen 71%, Sp 64%, p=0.006). Conclusions Although late VT/VF occurrence after primary PCI were less frequent than early VT/VF occurrence, patients with late VT/VF had a very poor prognosis. The most power predictor of late VT/VF were systolic longitudinal strain. Funding Acknowledgement Type of funding source: Public hospital(s). Main funding source(s): Clinical Center of Serbia
