    [Show abstract] [Hide abstract] ABSTRACT: Background: Comorbid elderly patients with non-ST-elevation myocardial infarction (non-STEMI) are underrepresented in randomized trials and undergo fewer cardiac catheterizations according to registries. Our aim was to compare the conservative and invasive strategies in these patients. Methods: Randomized multicenter study, including 106 patients (January 2012-March 2014) with non-STEMI, over 70years and with comorbidities defined by at least two of the following: peripheral artery disease, cerebral vascular disease, dementia, chronic pulmonary disease, chronic renal failure or anemia. Patients were randomized to invasive (routine coronary angiogram, n=52) or conservative (coronary angiogram only if recurrent ischemia or heart failure, n=54) strategy. Medical treatment was identical. The main endpoint was the composite of all-cause mortality, reinfarction and readmission for cardiac cause (postdischarge revascularization or heart failure), at long-term (2.5-year follow-up). Analysis of cumulative event rate (incidence rate ratio=IRR) and time to first event (hazard ratio=HR), were performed. Results: Cardiac catheterization/revascularization rates were 100%/58% in the invasive versus 20%/9% in the conservative arm. There were no differences between groups in the main endpoint (invasive vs conservative: IRR=0.946, 95% CI 0.466-1.918, p=0.877) at long-term. The invasive strategy, however, tended to improve 3-month outcomes in terms of mortality (HR=0.348, 95% CI 0.122-0.991, p=0.048), and of mortality or ischemic events (reinfarction or postdischarge revascularization) (HR=0.432, 95% CI 0.190-0.984, p=0.046). This benefit declined during follow-up. Conclusions: Invasive management did not modify long-term outcome in comorbid elderly patients with non-STEMI. The finding of a tendency towards an improvement in the short-term needs confirmation in larger studies (clinicaltrials.govNCT1645943).

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: The usefulness of B-type natriuretic peptide (BNP) as a marker of ischemia is controversial. BNP levels have predicted arrhythmias in various settings, but it is unknown whether they are related to exercise-induced ischemic ventricular arrhythmias. Material and methods: We analyzed in 63 patients (64 ±14 years, 65% male, 62% with known coronary disease) undergoing exercise stress single-photon emission computed tomography (SPECT) the association between plasma BNP values (before and 15 min after exercise) and the occurrence of ischemia or ventricular arrhythmias during the test. Results: Exercise test (8.1 ±2.7 min, 7.4 ±8.1 metabolic equivalents, 82 ±12% of maximal predicted heart rate) induced reversible perfusion defects in 23 (36%) patients. Eight (13%) patients presented significant arrhythmias (≥ 7 ventricular premature complexes/min, couplets, or non-sustained ventricular tachycardia during exercise or in the first minute of recovery). Median baseline BNP levels were 17.5 (12.4-66.4) pg/ml in patients developing scintigraphic ischemia and 45.6 (13.2-107.4) pg/ml in those without ischemia (p = 0.137). The BNP levels increased after exercise (34.4 (15.3-65.4)% increment over baseline, p < 0.001), but the magnitude of this increase was not related to SPECT positivity (35.7 (18.8-65.4)% vs. 27.9 (5.6-64.0)% in patients with and without ischemia, respectively, p = 0.304). No significant association was found between BNP values (at baseline or their change during the test) and ventricular arrhythmias. Conclusions: Plasma BNP values - at baseline or after exercise - were not associated with myocardial ischemia or with ventricular arrhythmia during exercise SPECT. These results highlight the limited usefulness of this biomarker to assess acute ischemia.

  • [Show abstract] [Hide abstract] ABSTRACT: Therapeutic fibrinolysis is ineffective in 40 % of ST-segment elevation acute myocardial infarction (STEMI) patients, but understanding of the mechanisms is incomplete. It was our aim to compare the composition of coronary thrombus in lysis-resistant STEMI patients with that of lysis-sensitive patients. Intracoronary thrombi (n=64) were obtained by aspiration in consecutive STEMI patients. Of them, 20 had received fibrinolysis and underwent rescue percutaneous coronary intervention (r-PCI, lysis-resistant patients) and 44 underwent primary PCI (p-PCI). Lysis-sensitivity was determined in vitro by clot permeability measurements and turbidimetric lysis in plasma of 44 patients undergoing p-PCI and 20 healthy donors. Clot-lysis sensitivity was defined as a clot-lysis time not greater than 1 SD over the mean of healthy donors. Coronary thrombus composition in 20 lysis-resistant and in 20 lysis-sensitive patients was analysed by immunofluorescence with confocal microscopy. Plasma biomarkers (P-selectin, VWF, PAI-1, t-PA, D-dimer, TF pathway markers, plasmin and CD34+) were measured simultaneously on peripheral blood. Lysis-resistant clots had higher levels of fibrin (p=0.02), P-selectin (p=0.03) and VWF (p=0.01) than lysis-sensitive clots. Among thrombi obtained ≤ 6 hours after onset of symptoms, those from lysis-resistant patients showed a higher content in fibrin than those from p-PCI patients (p=0.01). Plasma PAI-1 (p=0.02) and D-dimer levels were significantly higher (p=0.003) in lysis-resistant patients, whereas plasmin levels were lower (p=0.03). Multivariate analysis showed the content of fibrin and VWF within thrombus as predictors of thrombolysis resistance. In conclusion, coronary thrombi in STEMI patients resistant to fibrinolysis are characterised by higher fibrin, P-selectin and VWF content than lysis-sensitive thrombi.

    [Show abstract] [Hide abstract] ABSTRACT: Aims: Non-ST-elevation acute coronary syndrome (NSTE-ACS) is present in about 60-70% of patients admitted with acute coronary syndromes in clinical practice. This study provides a 'real-life' overview of NSTE-ACS patient characteristics, dual antiplatelet therapy clinical practice, and outcomes at both the time of discharge from hospital and up to 1-year post-discharge. Methods and results: A total of 10 registries (documenting 84 054 NSTE-ACS patients) provided data in a systematic manner on patient characteristics and outcomes for NSTE-ACS in general, and 6 of these (with 52 173 NSTE-ACS patients) also provided more specific data according to P2Y12 receptor inhibitor used. Unadjusted analyses were performed at the study level, and no formal meta-analysis was performed due to large heterogeneity between studies in the settings, patient characteristics, and outcome definitions. All-cause death rates across registries ranged from 0.76 to 4.79% in-hospital, from 1.61 to 6.65% at 30 days, from 3.66 to 7.16% at 180 days, and from 3.14 to 9.73% at 1 year. Major bleeding events were reported in up to 2.77% of patients while in hospital (in seven registries), up to 1.08% at 30 days (data from one registry only), and 2.06% at 1 year (one registry). Conclusions: There were substantial differences in the use of and patient selection for clopidogrel, prasugrel, and ticagrelor, which were associated with differences in short- and long-term ischaemic and bleeding events. In future registries, data collection should be performed in a more standardized way with respect to endpoints, definitions, and time points.

    [Show abstract] [Hide abstract] ABSTRACT: Background Long‐term prognosis of acute pulmonary edema (APE) remains ill defined. Methods and Results We evaluated demographic, echocardiographic, and angiographic data of 806 consecutive patients with APE with (CAD) and without coronary artery disease (non‐CAD) admitted from 2000 to 2010. Differences between hospital and long‐term mortality and its predictors were also assessed. CAD patients (n=638) were older and had higher incidence of diabetes and peripheral vascular disease than non‐CAD (n=168), and lower ejection fraction. Hospital mortality was similar in both groups (26.5% vs 31.5%; P=0.169) but APE recurrence was higher in CAD patients (17.3% vs 6.5%; P<0.001). Age, admission systolic blood pressure, recurrence of APE, and need for inotropics or endotracheal intubation were the main independent predictors of hospital mortality. In contrast, overall mortality (70.0% vs 57.1%; P=0.002) and readmission for nonfatal heart failure after a 45‐month follow‐up (10–140; 17.3% vs 7.6%; P=0.009) were higher in CAD than in non‐CAD patients. Age, peripheral vascular disease, and peak creatine kinase MB during index hospitalization, but not ejection fraction, were the main independent predictors of overall mortality, whereas coronary revascularization or valvular surgery were protective. These interventions were mostly performed during hospitalization index (294 of 307; 96%) and not intervened patients showed a higher risk profile. Conclusions Long‐term mortality in APE is high and higher in CAD than in non‐CAD patients. Considering the different in‐hospital and long‐term mortality predictors herein described, which do not necessarily involve systolic function, it is conceivable that a more aggressive interventional program might improve survival in high‐risk patients.

    [Show abstract] [Hide abstract] ABSTRACT: Aims: Among acute coronary syndromes (ACS), ST-segment elevation myocardial infarction (STEMI) has the most severe early clinical course. We aimed to describe the effectiveness and safety of P2Y12 receptor inhibitors in patients with STEMI based on the data from contemporary European ACS registries. Methods and results: Twelve registries provided data in a systematic manner on outcomes in STEMI patients overall, and seven of these also provided data for P2Y12 receptor inhibitor-based dual antiplatelet therapy. The registries were heterogeneous in terms of site, patient, and treatment selection, as well as in definition of endpoints (e.g. bleeding events). All-cause death rates based on the data from 84 299 patients (9612 patients on prasugrel, 11 492 on ticagrelor, and 27 824 on clopidogrel) ranged between 0.49 and 6.68% in-hospital, between 3.07 and 7.95% at 30 days (reported in 6 registries), between 8.15 and 9.13% at 180 days, and between 2.41 and 9.58% at 1 year (5 registries). Major bleeding rates were 0.09-3.55% in-hospital (8 registries), 0.09-1.65% at 30 days, and 1.96% at 1 year (only 1 registry). Fatal/life-threatening bleeding was rare occurring between 0.08 and 0.13% in-hospital (4 registries) and 1.96% at 1 year (1 registry). Conclusions: Real-world evidence from European contemporary registries shows that death, ischaemic events, and bleeding rates are lower than those reported in Phase III studies of P2Y12 inhibitors. Regarding individual P2Y12 inhibitors, patients on prasugrel, and, to a lesser degree, ticagrelor, had fewer ischaemic and bleeding events at all time points than clopidogrel-treated patients. These findings are partly related to the fact that the newer agents are used in younger and less ill patients.

    [Show abstract] [Hide abstract] ABSTRACT: Background and purpose: Selecting an ideal antithrombotic therapy for elderly patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) can be challenging since they have a higher thromboembolic and bleeding risk than younger patients. The current study aimed to assess the efficacy and safety of triple therapy (TT: oral anticoagulation plus dual antiplatelet therapy: aspirin plus clopidogrel) in patients ≥75 years of age with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). Methods: A prospective multicenter study was conducted from 2003 to 2012 at 6 Spanish teaching hospitals. A cohort study of consecutive patients with AF undergoing PCI and treated with TT or dual antiplatelet therapy (DAPT) was analyzed. All outcomes were evaluated at 1-year of follow-up. Results: Five hundred and eighty-five patients, 289 (49%) of whom were ≥75 years of age (79.6±3.4 years; 33% women) were identified. TT was prescribed in 55.9% of patients at discharge who had a higher thromboembolic risk (CHA2DS2VASc score: 4.23±1.51 vs 3.76±1.40, p = 0.007 and a higher bleeding risk (HAS-BLED ≥3: 88.6% vs 79.2%, p = 0.02) than those on DAPT. Therefore, patients on TT had a lower rate of thromboembolism than those on DAPT (0.6% vs 6.9%, p = 0.004; HR 0.08, 95% CI: 0.01-0.70, p = 0.004). Major bleeding events occurred more frequently in patients on TT than in those on DAPT (11.7% vs 2.4%, p = 0.002; HR 5.2, 95% CI: 1.53-17.57, p = 0.008). The overall mortality rate was similar in both treatment groups (11.9% vs 13.9%, p = 0.38); however, after adjustment for confounding variables, TT was associated with a reduced mortality rate (HR 0.33, 95% CI: 0.12-0.86, p = 0.02). Conclusions: In elderly patients with AF undergoing PCI, the use of TT compared to DAPT was associated with reduced thromboembolism and mortality rates, although a higher rate of major bleeding.

    [Show abstract] [Hide abstract] ABSTRACT: Background: The effects of dual antiplatelet therapy (DAPT) and triple therapy (TT: DAPT plus oral anticoagulation) in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) regarding to CHA 2 DS 2 -VASc score remain undefined.We compare the effect of TT vs. DAPT in this setting regarding the CHA 2 DS 2 -VASc score.Methods and Results:In a prospective multicenter registry, 585 patients (75.2% male, 73.2±8.2 years) with AF undergoing PCI were followed up during 1 year. Of them, 157 (26.8%) had a CHA 2 DS 2 -VASc=1, and 428 (73.2%) had a CHA 2 DS 2 -VASc ≥2. TT was prescribed in 51.6% with CHA 2 DS 2 -VASc=1 and in 55.5% with CHA 2 DS 2 -VASc ≥2. Patients with CHA 2 DS 2 -VASc=1 receiving TT had a similar thromboembolism rate to those on DAPT (1.2% vs. 1.3%, P=0.73), but more total (19.5% vs. 6.9%, P=0.01) and a tendency to more major (4.9% vs. 0%, P=0.06) bleeding. However, patients with CHA 2 DS 2 -VASc ≥2 receiving TT had a lower thromboembolism rate (1.7% vs. 5.3%, P=0.03) and a trend towards more bleeds (21.8% vs. 15.6%, P=0.06), with an excess of major bleeding (8.4% vs. 3.1%, P=0.01). Rates of major adverse cardiac events (MACE) in both CHA 2 DS 2 -VASc subgroups were similar, irrespective of treatment. In a Cox multivariate analysis, TT was associated to major bleeding, but not with MACE. Conclusions: In patients with AF and CHA 2 DS 2 -VASc=1 undergoing PCI, the use of TT involves a high risk of bleeding without a significant benefit in preventing thromboembolism.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Bilirubin may elicit cardiovascular protection and heme oxygenase-1 overexpression attenuated post-infarction ventricular remodeling in experimental animals, but the association between bilirubin levels and post-infarction remodeling is unknown. Materials and methods: In 145 patients with a first anterior ST-segment elevation acute myocardial infarction (STEMI), we assessed whether plasma bilirubin on admission predicted adverse remodeling (left ventricular end-diastolic volume [LVEDV] increase ≥20% between discharge and 6 months, estimated by magnetic resonance imaging). Results: Patients' baseline characteristics and management were comparable among bilirubin tertiles. LVEDV increased at 6 months (P < 0.001) with respect to the initial exam, but the magnitude of this increase was similar across increasing bilirubin tertiles (10.8 [30.2], 10.1 [22.9], and 12.7 [24.3]%, P = 0.500). Median (25-75 percentile) bilirubin values in patients with and without adverse remodeling were 0.75 (0.60-0.93) and 0.73 (0.60-0.92) mg/dL (P = 0.693). Absence of final TIMI flow grade 3 (odds ratio 3.92, 95% CI 1.12-13.66) and a history of hypertension (2.04, 0.93-4.50), but not admission bilirubin, were independently associated with adverse remodeling. Bilirubin also did not predict the increase in ejection fraction at 6 months. Conclusions: Admission bilirubin values are not related to LVEDV or ejection fraction progression after a first anterior STEMI and do not predict adverse ventricular remodeling. Key messages Bilirubin levels are inversely related to cardiovascular disease, and overexpression of heme oxygenase-1 (the enzyme that determines bilirubin production) has prevented post-infarction ventricular remodeling in experimental animals, but the association between bilirubin levels and the progression of ventricular volumes and function in patients with acute myocardial infarction remained unexplored. In this cohort of patients with a first acute anterior ST-segment elevation myocardial infarction receiving contemporary management, bilirubin levels on admission were not predictive of the changes in left ventricular volumes or ejection fraction at 6 months measured by serial cardiac magnetic resonance imaging. The data are contrary to a significant protective effect of bilirubin against post-infarction ventricular remodeling.

    [Show abstract] [Hide abstract] ABSTRACT: Patients who have undergone angioplasty with stenting can be reintegrated into normal life at an early stage, thanks to the absence of sequelae associated with the procedure itself. Consequently, these patients can be involved earlier in the second stage of cardiac rehabilitation. Although rehabilitation for coronary patients follows the general guidelines used for all patients, which were developed with the secondary prevention of coronary artery atherosclerosis in mind, the specific form of rehabilitation adopted for each individual with ischemic heart disease will depend on the patient's circumstances, including the revascularization technique used. Regular physical exercise (i.e. physical training), in itself, has substantial cardiovascular benefits for both primary and secondary cardiovascular prevention. In patients who have had a myocardial infarction, training decreases mortality, increases functional capacity and improves ventricular function and remodeling. It is also thought to boost the collateral circulation. In addition, training improves endothelial function and stimulates the circulation of stem cells. It has been shown that physical training after percutaneous revascularization decreases the number of cardiac events. Moreover, in patients with stable angina, it results in fewer events than percutaneous revascularization.

  • [Show abstract] [Hide abstract] ABSTRACT: Background: The role of acute arterial hypertension in acute pulmonary edema (APE) as an associated or triggering phenomenon has been poorly investigated and is relevant to patient management. Methods: This was a prospective observational study of clinical, electrocardiographic, and echocardiographic characteristics of patients with APE. Potential triggers, including acute coronary syndrome (ACS), rapid atrial fibrillation (AF) (≥ 120 bpm in AF), fever > 38°C or volume overload, isolated acute hypertension (systolic blood pressure ≥ 170 mm Hg), and unknown factors were investigated. Results: There were 742 patients, 578 with coronary artery disease (78%), 116 with valvular heart disease or cardiomyopathy (16%), and 47 without identifiable heart disease (6%). ACS was present in 482 (65%) patients (silent in 154 of them), AF was present in 76 (10%) patients, fever/volume overload was present in 62 (8%) patients, acute hypertension was present in 50 (7%) patients, and no apparent trigger was seen in 72 (10%) patients. Admission hypertension occurred in 260 patients (35%): 155 (60%) with ACS (silent in 49 [32%]), 36 (14%) with AF, 19 (7%) with fever/volume overload, and 59 (19%) as an isolated trigger. Similar results were obtained when analyzing patients using coronary angiography (467 patients [63%]). Acute hypertension was present more frequently in patients with severe hypoventilation (arterial Pco2 > 60 mm Hg) than in those without (57% vs 29%; P < 0.001) and in those without moderate-severe mitral regurgitation than in those with (51% vs 30%; P < 0.001). Conclusions: In patients with APE, with or without ACS, acute hypertension is often present but mainly as an associated/reactive phenomenon and seems favoured by severe hypoventilation. Silent myocardial ischemia/necrosis deserves systematic investigation because it is not rare that it may be the underlying cause of APE.

    [Show abstract] [Hide abstract] ABSTRACT: Takotsubo syndrome (TKS) usually mimics an acute coronary syndrome. However, several clinical forms have been reported. Our aim was to assess if different stressful triggers had prognostic influence on TKS, and to establish a working classification. We performed an analysis including patients with TKS between 2003-2013 from our prospective local database and the RETAKO National Registry, fulfilling Mayo criteria. Patients were divided in two groups regarding their potential triggers: (a) none/psychic stress as 'primary forms' and (b) physical factors (asthma, surgery, trauma, etc.) as 'secondary forms'. Finally, 328 patients were included, 90.2% women, with a mean age of 69.7 years. Patients were divided into primary TKS (n=265) and 63 secondary TKS groups. Age, gender, previous functional class and cardiovascular risk profile displayed no differences between groups before admission. However, primary-TKS patients suffered a main complaint of chest pain (89.4% vs 50.7%, p<0.0001) with frequent vegetative symptoms. Regarding treatment before admission, there were no differences either. During admission, differences were related to more intensive antithrombotic and anxiolytic drug use in the primary TKS group. Inotropic and mechanical ventilation use was higher in the secondary cohort. After discharge, a more frequent prescription of beta-blockers and statins in primary-TKS patients was seen. Secondary forms displayed more in-hospital stay and evolutive complications: death (hazard ratio (HR): 3.41; 95% confidence interval (CI): 1.14-10.16, p=0.02), combined event variable (MACE) (HR: 1.61; 95% CI: 1.01-2.6, p=0.04) and recurrences (HR: 1.85; 95% CI: 1.06-3.22, p=0.02). Secondary TKS could present or mark worse short and long-term prognoses in terms of mortality, recurrences and readmissions. We propose a simple working nomenclature for TKS. © The European Society of Cardiology 2015.

  • [Show abstract] [Hide abstract] ABSTRACT: Patient registries that document real-world clinical experience play an important role in cardiology as they complement the data from randomised controlled trials, provide valuable information on drug use and clinical outcomes, and evaluate to what extent guidelines are followed in practice. The Platelet Inhibition Registry in ACS EvalUation Study (PIRAEUS) project is an initiative of registry holders who are managing national or international registries observing patients with acute coronary syndromes (ACS). The aim of PIRAEUS is to systematically compare and combine available information/insights from various European ACS registries with a focus on P2Y12 inhibitors. The present publication introduces the 17 participating registries in narrative and tabular form, and describes which ACS groups and which dual antiplatelet therapies were investigated. It sets the basis for upcoming publications that will focus on effectiveness and safety of the antiplatelets used.

    [Show abstract] [Hide abstract] ABSTRACT: Mechanical factors may contribute to ischemic ventricular arrhythmias. GsMtx4 peptide, a selective stretch-activated channel blocker, inhibits stretch-induced atrial arrhythmias. We aimed to assess whether GsMtx4 protects against ventricular ectopy and arrhythmias following coronary occlusion in swine. First, the effects of 170-nM GsMtx4 on the changes in the effective refractory period (ERP) induced by left ventricular (LV) dilatation were assessed in 8 isolated rat hearts. Then, 44 anesthetized, open-chest pigs subjected to 50-min left anterior descending artery occlusion and 2-h reperfusion were blindly allocated to GsMtx4 (57 μg/kg iv. bolus and 3.8 μg/kg/min infusion, calculated to attain the above concentration in plasma) or saline, starting 5-min before occlusion and continuing until after reflow. In rat hearts, LV distension induced progressive reductions in ERP (35±2, 32±2, and 29±2 ms at 0, 20, and 40 mmHg of LV end-diastolic pressure, respectively, P<0.001) that were prevented by GsMTx4 (33±2, 33±2, and 32±2 ms, respectively, P=0.002 for the interaction with LV end-diastolic pressure). Pigs receiving GsMtx4 had similar number of ventricular premature beats during the ischemic period as control pigs (110±28 vs. 103±21, respectively, P=0.842). There were not significant differences among treated and untreated animals in the incidence of ventricular fibrillation (13.6 vs. 22.7%, respectively, P=0.696) or tachycardia (36.4 vs. 50.0%, P=0.361) or in the number of ventricular tachycardia episodes during the occlusion period (1.8±0.7 vs. 5.5±2.6, P=0.323). Thus, GsMtx4 administered under these conditions does not suppress ventricular ectopy following coronary occlusion in swine. Whether it might protect against malignant arrhythmias should be tested in studies powered for these outcomes.
