OnBehalf Portuguese Registry of Acute Coronary Syndromes (ProACS) Introduction Brain natriuretic peptide (BNP) is a highly sensitive and specific biomarker on the extension of myocardial infarction, strongly related to short and long-term prognosis in patients with ST elevation myocardial infarction (STEMI). Objective To evaluate diagnostic and prognostic value of BNP levels in a Portuguese cohort of STEMI patients. Material and methods Retrospective analysis of patients admitted with STEMI included in the Portuguese Registry of Acute Coronary Syndromes between 2010-19. Patients were divided in three groups regarding BNP: Group 1 if BNP <100 pg/ml; Group 2 100 ≤ BNP < 400 pg/ml and Group 3 ≥400 pg/ml. Independent predictors of a composite of all-cause mortality and rehospitalization for cardiovascular causes were assessed by multivariate logistic regression. Results 1650 patients were included, mean age 64 ± 13 years, 75.4% male. 39.0% (n = 643) integrated group 1, 39.5% (n = 652) group 2 and 21.5% (n = 355) group 3. Group 3 patients were significantly older (58 ± 11 vs 66 ± 13 vs 72 ± 12 years, p < 0.001), had more classic cardiovascular risk factors, except for smoker status, and more previous history of cardiovascular disease, chronic kidney disease, chronic obstructive pulmonary disease and cancer. Anterior STEMI was the most frequent location (51.1%), however group 3 patients presented with lower systolic blood pressure (136 ± 30 vs 140 ± 31 vs 131 ± 28 mmHg, p < 0.001) and higher heart rate (76 ± 17 vs 77 ± 19 vs 84 ± 26 bpm, p < 0.001) and KK class (KK class > I 5.6 vs 9.5 vs 28.5%, p < 0.001). They also presented higher levels of creatinine (1 ± 0.5 vs 1.2 ± 0.9 vs 1.5 ± 1 mg/dl, p < 0.001) and the lowest levels of hemoglobin (13.5 ± 1.6 vs 12.6 ± 1.9 vs 11.7 ± 2.1 g/dl, p < 0.001). Mean ejection fraction (EF) was lower in group 3 (58 ± 11 vs 53 ± 12 vs 44 ± 13%, p < 0.001). Multivessel disease was more common in group 3 (34.8 vs 44.8 vs 51.3%, p < 0.001), where a higher percentage was proposed to medical therapy (2.8 vs 3.5 vs 8.5%, p < 0.001). In the patients proposed to revascularization, although not statistically significant, there was a trend towards surgical revascularization or hybrid approach. In-hospital complications were more frequent in group 3, especially heart failure (HF) (18.9% mean vs 45.4%, p < 0.001), and mortality was seven times superior in group 3 versus group 1 (1.2% vs. 8.5%, p < 0.001). The composite endpoint of 1-year mortality and cardiovascular rehospitalization occurred in 12%. After propensity score application, the 1-year endpoint total mortality rate and cardiovascular readmission was 20.3%, and higher BNP was associated with higher rates (p < 0.001). Predictor factors for the composite endpoint, evaluated through Cox multivariate regression were previous HF, multivessel disease, EF < 30% and the use of nitrates and aldosterone antagonists. The use of aspirin was a protector factor. Conclusion BNP levels during index hospitalization were a powerful prognostic biomarker for all-cause mortality MACE in patients admitted with STEMI.

Background: There are no data regarding the mortality rate, risks and benefits of particular reperfusion methods and pharmacological treatment complications in patients aged over 100 years with acute coronary syndromes. We sought to assess the treatment of myocardial infarction (MI) in patients older than 100 years and to determine prognostic factors for this group. Methods: Among the 716,566 patients recorded between 2003 and 2018 in the Polish Registry of Acute Coronary Syndromes, 104 patients aged ≥100 with MI were included. The patients were categorized into two groups: group 1 received conservative treatment (64 patients), and group 2 received invasive strategy (40 patients). Results: The frequencies of in-hospital mortality, MI and stroke were similar in both arms. No difference in the frequency of the combined endpoint (death, reinfarction, stroke) was noted. Invasive treatment was more advantageous for 12-month outcomes; 50 patients in group 1 (79%) and 23 patients in group 2 (57.50%) died (p = 0.017). The multivariate analysis identified the lower left ventricular ejection fraction (EF) (Hazard Ratio (HR) = 0.96; 95% Confidence Interval (CI): 0.94–0.99; p = 0.012), lack of coronary angiography (HR = 0.49; 95% CI: 0.24–0.99; p = 0.048) and cardiac arrest (HR = 4.61; 95% CI: 1.64–12.99; p = 0.0038) as predictors of 12-month mortality in this group. Conclusions: Invasive MI treatment may be beneficial for selected very old patients.

<b><i>Introduction:</i></b> The effect of high serum ferritin levels on long-term mortality in hemodialysis patients is unknown. The relationship between serum ferritin levels and 5-year all-cause mortality in hemodialysis patients was investigated in this study. <b><i>Methods:</i></b> A total of 173 prevalent hemodialysis patients were included in this study. The patients were followed for up to 5 years and divided into 3 groups according to time-averaged serum ferritin levels (group 1: serum ferritin &#x3c;800 ng/mL, group 2: serum ferritin 800–1,500 ng/mL, and group 3: serum ferritin &#x3e;1,500 ng/mL). Along with the serum ferritin levels, other clinical and laboratory variables that may affect mortality were also included in the Cox proportional-hazards regression analysis. <b><i>Results:</i></b> Eighty-one (47%) patients died during the 5-year follow-up period. The median follow-up time was 38 (17.5–60) months. The 5-year survival rates of groups 1, 2, and 3 were 44, 64, and 27%, respectively. In group 3, the survival was lower than in groups 1 and 2 (log-rank test, <i>p</i> = 0.002). In group 1, the mortality was significantly lower than in group 3 (HR [95% CI]: 0.16 [0.05–0.49]; <i>p</i> = 0.001). In group 2, the mortality was also lower than in group 3 (HR [95% CI]: 0.32 [0.12–0.88]; <i>p</i> = 0.026). No significant difference in mortality between groups 1 and 2 was found (HR [95% CI]: 0.49 [0.23–1.04]; <i>p</i> = 0.063). <b><i>Conclusion:</i></b> Time-averaged serum ferritin levels &#x3e;1,500 ng/mL in hemodialysis patients are associated with an increased 5-year all-cause mortality risk.

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.

Abstract Background Left ventricular (LV) remodelling after ST-segment elevation myocardial infarction (STEMI) is a complex pathological process which has been associated with long-term cardiovascular adverse events. The current definition of LV remodelling is usually based on the change in LV end-diastolic volume (LVEDV). An increase in LVEDV, however, may also be considered an adaptive response to maintain effective LV ejection fraction (LVEF) in LV remodelling. Purpose To reclassify post-infarct LV remodelling according to the change in LVEDV and LVEF from baseline and to determine the prognostic relevance of integrated LV remodelling and systolic function groups. Methods A total of 1859 patients with STEMI who received primary percutaneous coronary intervention (PCI) and guideline-directed medical treatment, were retrospectively evaluated. Four LV remodelling subgroups were identified, based on the change in LVEDV and LVEF from baseline to 6 months post-infarct. ≥20% increase in LVEDV, compared to baseline, was defined as LV dilatation, while any increase or decrease in LVEF compared to baseline was used to categorise remodelling further according to systolic function. Study endpoints were all-cause mortality and the composite of all-cause mortality and heart failure (HF) hospitalisation. Results The mean age of the study population was 60±11 years and the majority were men (76.4%). 402 patients showed LVEDV≥20% and LVEF increase (Group 1), 952 patients LVEDV≤20% and LVEF increase (Group 2), 325 patients LVEDV≤20% and LVEF decrease (Group 3) and 180 patients LVEDV≥20% and LVEF decrease (Group 4). During a median follow-up of 89 (IQR 64; 113) months, all-cause mortality occurred in 256 patients (13.8%), HF hospitalisation in 40 patients (2.2%) and the composite endpoint in 279 patients (15.0%). All-cause mortality was significantly higher in Group 4 (21.7%, chi-square p=0.002) compared to other groups (15.4% in Group, 12.9% in Group 2 and 9.8% in Group 3). The composite endpoint was also significantly more frequent in Group 4 (25.6%, chi-square p&lt;0.001) compared with the other groups (16.2% in Group 1, 13.8% in Group 2 and 11.4% in Group 3). Mean survival time (Figure 1A) and event-free survival time for the composite endpoint (Figure 1B) were significantly lower in Group 4 (122 months 95% CI 115–128, p=0.004 and 117 months 95% CI 110–124, p&lt;0.001, respectively) compared to other groups. Conclusion Patients with LVEDV≥20% and a LVEF decrease at 6 months after STEMI experienced all-cause mortality and the composite endpoint of all-cause mortality and HF hospitalisation more frequently compared to other LV remodelling groups. Patients with an increase in LVEDV and a decrease in LVEF 6 months after STEMI, may benefit from careful surveillance and preventative strategies. KM comparison for study endpoints.

Introduction: Although albuminuria evaluated with urinary albumin-to-creatinine ratio (UACR) was shown to be a prognostic marker in patients with heart failure, measurement of UACR needs special equipment. Urine dipstick test is a simple and convenient method which is available even in community-based health care. Hypothesis: We hypothesized that dipstick proteinuria might be a prognosticator in HFpEF. Methods: We assessed 738 discharged-alive patients in the PURSUIT-HFpEF registry. Patients received urine dipstick test, and were divided into 2 groups according to the absence or presence of proteinuria (proteinuria trace or more). The study endpoint was a composite of all-cause mortality and HF hospitalization. Results: Median age was 82 years and 410 patients were female. Four hundred thirty-four patients: proteinuria-(group 1); 304 patients: proteinuria+(group 2). Group 2 was more likely male with higher frequency of diabetes, previous myocardial infarction and chronic kidney disease, but less likely to take ACEIs than group 1. Higher blood pressure, NT-proBNP, creatinine, E/e’, TRPG, and LV mass index were observed in group 2 than group 1. The composite endpoint and HF hospitalization occurred more often in group 2 than group 1 (HR: 1.43, 95%CI: 1.09-1.87, log-rank P=0.009; HR: 1.57, 95%CI: 1.14-2.15, log-rank P=0.005, respectively); but all-cause mortality did not (HR: 1.40, 95%CI: 0.92-2.11, log-rank P=0.113). Multivariable Cox regression adjusting for NT-proBNP, eGFR and other major confounding factors showed that proteinuria was associated with the composite endpoint (HR: 1.42, 95% CI: 1.05-1.94, P=0.026), and HF hospitalization (HR: 1.51, 95%CI: 1.04-2.18, P=0.030), but not with all-cause mortality (HR: 1.51, 95%CI:0.94-2.43, P=0.092). Conclusions: Dipstick proteinuria may be a prognostic marker in patients with HFpEF. Evaluation of proteinuria by urine dipstick test may be a simple but useful method for risk stratification in HFpEF.

Aim: To investigate the serotonin and von Willebrand factor (vWF) concentrations among unstable angina (UA) patients without and with progression toward myocardial infarction (outcome) and to assess the utility of both as prognostic markers of UA complications. Materials and methods: In observational cohort study, we recruited 103 patients with ischemic heart disease (the median age 65.0 (59.0-69.0) years, 45 females (43.7%)). After full set of investigations including high sensitive Troponin I test and 28-day follow-up period, we defined three groups: Group 1 - stable angina patients (n=22) as control, Group 2 - UA patients without outcome (n=71), Group 3 - UA patients with outcome (n=10). We analyzed the blood plasma serotonin content by the ion-exchange chromatography with measurement of serotonin on fluorescence spectrophotometer. VWF concentration was determined by ELISA. We compared the concentrations of observed parameters among the groups with the Kruskal-Wallis test (with post-hoc Mann-Whitney test with Bonferroni-Holm correction). We assessed binary logistic models, receiver operating characteristic curves, calculated sensitivity (Se), specificity (Sp), and positive likelihood ratio (LR+) for each indicator. Results: We registered elevation in serotonin concentration and decline in vWF concentration in Group 3 in comparison with Group 2 (22.670 (20.687-24.927) μg/ml vs 11.980 (8.120-15.000) μg/ml, p< 0.001, and 0.117 (0.109-0.120) rel.units/ml vs 0.134 (0.127-0.143) rel.units/ml, p < 0.001) and Group 1 (12.340 (10.052-13.619) μg/ml, p < 0.001, and 0.137 (0.127-0.156) rel.units/ml, p < 0.001), respectively. No significant differences in serotonin and vWF concentrations between Group 1 and Group 2 were detected (p=0.81 and p=0.36, respectively). The probability of outcome increased significantly (by 60.7% and 59.7%, LR+ 19.0 [6.0, 60.0] and 18.0 [3.9, 80.0]) if serotonin concentration was above 21.575 μg/ml (Se=80.0%, Sp=95.8%, AUC=0.975) and vWF concentration was below 0.114 rel.units/ml (Se=50.0%, Sp=97.2%, AUC=0.973), respectively. Conclusions: Serotonin and vWF as biomarkers are demonstrated promising results for rule-in the patients with risk of short-term UA progression toward myocardial infarction.

Aim. Analysis of hospital and long-term results of carotid endarterectomy (CEA) in different periods of acute cerebrovascular event (ACVE). Materials and Methods. The given study was retrospective and was conducted using the method of patients sampling. In the period from 2010 to 2019, 1113 patients with ACVE in history who were later conducted CEA, were selected. Depending on the time interval between the last ACVE and CAE, all the patients were divided into 4 groups: the 1st group in the acutest period of ACVE (1-3 days) (n=24; 2.2%); the 2nd group in the acute period of ACVE (up to 28 days) (n=493; 44.3%); the 3rd group in the early rehabilitation period of ACVE (up to 6 months) (n=481; 43.2%); the 4th group in the late rehabilitation period of ACVE (up to 2 years) (n=115; 10.3%). The long-term period was 34.812.5 months. Results. In the hospitalization period of observation the following complications were found: lethal outcome ((group 1 0%; group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р=0.16)); myocardial infarction ((group 1 0%; group 2 0.4% (n=2); group 3 0%; group 4 0.9% (n=1); р=0.35)); ACVE/transient ischemic attack (TIA), ((group 1 4.2% (n=1); group 2 0.4% (n=2); group 3 0.2% (n=1); group 4 0%; р1-2=0.01; р1-3=0.009; р1-4=0.01)). By the end of hospitalization period the composite endpoint consisting of lethal outcome + myocardial infarction + ACVE/TIA made in group 1 4.2% (n=1), in group 2 1.2% (n=6), in group 3 0.4% (n=2), in group 4 2.6% (n=3), р=0.08. Complications of the long-term follow-up period were: lethal outcome from all causes ((group 1 25% (n=6); group 2 5.5% (n=27); group 3 7.3% (n=35); group 4 14% (n=16); р1-2=0.002; р1-3=0.008; р2-4=0.012)); lethal outcome from cardiovascular causes ((group 1 4.2% (n=1); group 2 3.6% (n=18); group 3 4.8% (n=23); group 4 5.2% (n=6); р=0.79)), myocardial infarction ((group 1 12.5% (n=3); group 2 3.6% (n=18); group 3 5.4% (n=26); group 4 6.1% (n=7); р=0.15)), ACVE/TIA ((group 1 16.6% (n=4); group 2 6.3% (n=31); group 3 6% (n=29); group 4 11.3% (n=13); р=0.05)); composite endpoint including lethal outcome + myocardial infarction + ACVE/TIA ((group 1 54.2% (n=13); group 2 15.4% (n=76); group 3 18.7% (n=90); group 4 31.3% (n=36); р1-2=0.0001; р1-3=0.0001; р1-4=0.005; р2-4=0.0006; р3-4=0.012)). Conclusion. Application of CEA demonstrated effectiveness and safety in the acute and early rehabilitation period of ACVE.

Purpose: The purpose of the present study was to evaluate the effects of different loading doses of clopidogrel on ST segment resolution on ECG, changes in cardiac enzyme levels and serum levels of high-sensitivity C-reactive protein (Hs-CRP) in patients with ST elevated myocardial infarction (STEMI) treated with fibrinolytic therapy. Methods: Patients admitted to our cardiology clinic with a diagnosis of STEMI and treated with fibrinolytic therapy were included: Group 1 (n=58) received a 300 mg loading dose of clopidogrel, Group 2 (n=55) a 450 mg loading dose and Group 3 (n=59) a 600 mg loading dose. A 75 mg/d maintanence dose of clopidogrel was given in all groups. Results: All demographic characteristics and baseline laboratory parameters were statistically similar among three groups (p > 0.05). When ST resolution periods were compared, most patients in Group 3 had ST resolution at 30 minutes; Group 2 at 60 minutes and Group 1 at 90 minutes (p < 0.05). Peak levels of creatine kinase (CK) and CK-MB were as follows: Group 3, 8th hour, Group 1 and 2, 12th hour. Peak levels of those enzymes were significantly lower in Group 3 than in Group 1 and 2 ( < 0.05). Although basal hs-CRP levels of all groups were similar, the increase in hs-CRP levels at 48 hours was lower with higher clopidogrel loading doses (p < 0.05). Conclusion: In this study comparing three different clopidogrel loading doses, the higher doses provided earlier ECG resolution, earlier and lower peak CK and CK-MB levels and lower levels of hs-CRP.

The aim of this study was to analyse the inpatient and long-term results of hybrid surgery, incorporating percutaneous coronary intervention (PCI) and different types of carotid endarterectomy (CEA). Materials and methods. A prospective, open-label cohort comparison study was conducted in 20182020 and included 363 patients with atherosclerosis of both the internal carotid artery (ICA) and coronary artery, who underwent hybrid revascularization of the brain and myocardium. All patients were divided into four groups based on the revascularization strategy: group 1 (n = 107; 29.5%) PCI + eversion CEA; group 2 (n = 98; 27%) PCI + classic CEA with patch angioplasty; group 3 (n = 72; 19.8%) PCI + glomus-sparing CEA according to R.A. Vinogradov; and group 4 (n = 86; 23.7%) PCI + glomus-sparing CEA according to A.N. Kazantsev. The follow-up period was 20.8 8.0 months. The patient received a loading dose of clopidogrel (300 mg) before the PCI, and the procedure was then performed in an endovascular operating room. A radial artery catheter was inserted, and the patient received 10,000 IU of intravenous heparin before the procedure. After the PCI, the patient was taken to the vascular operating room, where they underwent the CEA. The patient received 5,000 IU of intravenous heparin before artery clamping. Glomus-sparing CEA according to A.N. Kazantsev was performed as follows: an arteriotomy was conducted along the internal edge of the external carotid artery (ECA), adjacent to the carotid sinus and 23 cm above the ostium, and extending to the common carotid artery (CCA) (also 23 cm below the ECA ostium), depending on the size of the atherosclerotic plaque. The ICA was transected in the area bound by the ECA and CCA walls. Eversion CEA of the ICA was performed, followed by open CEA of the ECA and CCA. The ICA was implanted in its previous position in the preserved area. Results. No mortality was recorded during the inpatient follow-up period. All cases of myocardial infarction occurred after eversion and classic CEA: 3 in group 1 (2.8%) and 1 in group 2 (1.02%); р = 0.2. No ischaemic stroke was recorded only in patients who underwent CAE according to A.N. Kazantsev (р = 0.66); however, ischaemic stroke occurred in two patients in group 1 (1.8%), in two patients in group 2 (2.04%) and in one patient in group 3 (1.38%). The highest number of cardiovascular events occurred in group 1, due to carotid glomus injury, which led to poorly controlled hypertension during the inpatient stay. This tendency influenced the composite endpoints (death + myocardial infarction + ischaemic stroke), which were highest in group 1 (5 or 4.6%) compared to 3 (3.06%), 1 (1.38%) and 0 in groups 24, respectively (р = 0.18). The groups were comparable in the frequency of long-term complications. However, the incidence of ICA restenosis was lowest and no ECA thrombosis/occlusion was observed after glomus-sparing CEA according to R.A. Vinogradov and A.N. Kazantsev. Conclusion. A hybrid PCI + CEA for brain revascularization should be glomus-sparing. CEA according to A.N. Kazantsev was characterized by lack of procedural arteriotomy complications. This procedure enables blood pressure monitoring in the postoperative period, thus minimizing the risk of cardiovascular complications.
