Pseudoaneurisma ventricular izquierdo incidental tras un infarto de miocardio

We present the clinical case of a 61-year-old man who presented in the emergency room with hematemesis. In the evaluation a large pseudoaneurysm in the lateral wall of the left ventricle secondary to a myocardial infarction of indeterminate time of evolution was incidentally found. Different imaging techniques were used to define the characteristics of the pseudoaneurysm and to plan the therapeutic approach. This clinical case is a good example of an incidental finding in a cardiac imaging test that can have a deep influence in the prognosis of a patient. Likewise, we hypothesized the association of an acute myocardial infarction secondary and stress gastritis.Presentamos un varón de 61 años que acude al servicio de urgencias por hematemesis. De forma incidental se detecta un pseudoaneurisma en la pared lateral del ventrículo izquierdo, consecuencia de un infarto de tiempo de evolución indeterminado. Las diferentes técnicas de imagen permitieron definir las características del pseudoaneurisma para establecer el mejor plan terapéutico. La importancia de este caso radica en que los hallazgos incidentales en las diferentes técnicas de imagen tienen relevancia en el pronóstico del paciente. Así mismo, se plantea la posible asociación entre la hematemesis y una gastritis por estrés secundaria al evento isquémico agudo

Comparative external validation of the PRECISE-DAPT and PARIS risk scores in 4424 acute coronary syndrome patients treated with prasugrel or ticagrelor

Background: The PRECISE-DAPT and PARIS risk scores (RSs) were recently developed to help clinicians at individualizing the optimal dual antiplatelet therapy duration (DAPT) after percutaneous coronary intervention (PCI). Nevertheless, external validation of these RSs it has not yet been performed in ACS (acute coronary syndrome) patients treated with prasugrel or ticagrelor in a real- world scenario. Methods: 4424 ACS patients who underwent PCI and survived to hospital discharge, from January 2012 to December 2016 at 12 European centers, were included. PRECISE-DAPT and PARIS bleeding RS, as well as PARIS ischemic RS, were computed, and their performance at predicting major bleeding (MB; BARC type 3 or 5) and ischemic events (MI and stent thrombosis) during follow up was compared. Results: After a median follow-up of 14 (interquartile range 12–20.9) months, 83 (1.88%) patients developed MB and 133 (3.0%) suffered an ischemic episode. PRECISE-DAPT performed better than PARIS bleeding RS (c-statistic = 0.653 vs. 0.593; p =.01 for comparison) in predicting MB. The RSs performance for MB prediction remained consistent in STEMI patients (c-statistic = 0.632 vs 0.575) or in those treated with prasugrel (c-statistic = 0.623 vs 0.586). PARIS ischemic RS exhibited superior discrimination in predicting ischemic complications compared to PRECISE-DAPT (c-statistic = 0.604 vs 0.568 p =.05 for comparison). Conclusion: Our data provide support to the use of PRECISE-DAPT in MB risk stratification for patients receiving DAPT in form of aspirin and prasugrel or ticagrelor whereas the PARIS ischemic RS has potential to complement the risk prediction with respect to ischemic events

Average daily ischemic versus bleeding risk in patients with ACS undergoing PCI: Insights from the BleeMACS and RENAMI registries

Background: The risk of recurrent ischemia and bleeding after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) may vary during the first year of follow-up according to clinical presentation, and medical and interventional strategies. Methods: BleeMACS and RENAMI are 2 multicenter registries enrolling patients with ACS treated with PCI and clopidogrel, prasugrel, or ticagrelor. The average daily ischemic and bleeding risks (ADIR and ADBR) in the first year after PCI were the primary end points. The difference between ADBR and ADIR was calculated to estimate the potential excess of bleeding/ischemic events in a given period or specific subgroup. Results: A total of 19,826 patients were included. Overall, in the first year after PCI, the ADBR was 0.008085%, whereas ADIR was 0.008017% (P =.886). In the first 2 weeks ADIR was higher than ADBR (P =.013), especially in patients with ST-segment elevation myocardial infarction or incomplete revascularization. ADIR continued to be, albeit non-significantly, greater than ADBR up to the third month, whereas ADBR became higher, although not significantly, afterward. Patients with incomplete revascularization had an excess in ischemic risk (P =.003), whereas non–ST-segment elevation ACS patients and those on ticagrelor had an excess of bleeding (P =.012 and P =.022, respectively). Conclusions: In unselected ACS patients, ADIR and ADBR occurred at similar rates within 1 year after PCI. ADIR was greater than ADBR in the first 2 weeks, especially in ST-segment elevation myocardial infarction patients and those with incomplete revascularization. In the first year, ADIR was higher than ADBR in patients with incomplete revascularization, whereas ADBR was higher in non–ST-segment elevation ACS patients and in those discharged on ticagrelor

New Cancer Diagnosis After Bleeding in Anticoagulated Patients With Atrial Fibrillation.

Background Bleeding is frequent in patients with atrial fibrillation (AF) treated with oral anticoagulant therapy, and may be the first manifestation of underlying cancer. We sought to investigate to what extent bleeding represents the unmasking of an occult cancer in patients with AF treated with oral anticoagulants. Methods and Results Using data from CardioCHUVI-AF (Retrospective Observational Registry of Patients With Atrial Fibrillation From Vigo's Health Area), 8753 patients with AF aged ≥75 years with a diagnosis of AF between 2014 and 2017 were analyzed. Of them, 2171 (24.8%) experienced any clinically relevant bleeding, and 479 (5.5%) were diagnosed with cancer during a follow-up of 3 years. Among 2171 patients who experienced bleeding, 198 (9.1%) were subsequently diagnosed with cancer. Patients with bleeding have a 3-fold higher hazard of being subsequently diagnosed with new cancer compared with those without bleeding (4.7 versus 1.4 per 100 patient-years; adjusted hazard ratio [HR], 3.2 [95% CI, 2.6-3.9]). Gastrointestinal bleeding was associated with a 13-fold higher hazard of new gastrointestinal cancer diagnosis (HR, 13.4; 95% CI, 9.1-19.8); genitourinary bleeding was associated with an 18-fold higher hazard of new genitourinary cancer diagnosis (HR, 18.1; 95% CI, 12.5-26.2); and bronchopulmonary bleeding was associated with a 15-fold higher hazard of new bronchopulmonary cancer diagnosis (HR, 15.8; 95% CI, 6.0-41.3). For other bleeding (nongastrointestinal, nongenitourinary, nonbronchopulmonary), the HR for cancer was 2.3 (95% CI, 1.5-3.6). Conclusions In patients with AF treated with oral anticoagulant therapy, any gastrointestinal, genitourinary, or bronchopulmonary bleeding was associated with higher rates of new cancer diagnosis. These bleeding events should prompt investigation for cancers at those sites.S

Real-world data of Prasugrel vs. Ticagrelor in acute myocardial infarction: results from the RENAMI registry

BACKGROUND: Limited data are available concerning differences in clinical outcomes for real-life patients treated with ticagrelor versus prasugrel after percutaneous coronary intervention (PCI). OBJECTIVE: Our objective was to determine and compare the efficacy and safety of ticagrelor and prasugrel in a real-world population. METHODS: RENAMI was a retrospective, observational registry including the data and outcomes of consecutive patients with acute coronary syndrome (ACS) who underwent primary PCI and were discharged with dual antiplatelet therapy (DAPT) between January 2012 and January 2016. The mean follow-up period was 17 ± 9 months. In total, 11 university hospitals from six European countries participated. After propensity-score matching, there were no substantial differences in the baseline clinical and interventional features. All patients were treated with acetylsalicylic acid plus prasugrel 10 mg once daily or acetylsalicylic acid plus ticagrelor 90 mg twice daily. Mean duration of DAPT was 12.04 ± 3.4 months with prasugrel and 11.90 ± 4.1 months with ticagrelor (p = 0.47). The primary and secondary endpoints were long-term net adverse clinical events (NACE) and major adverse cardiovascular events (MACE), respectively, along with their single components. Subgroup analysis for freedom from NACE and MACE was performed according to length of DAPT and clinical presentation [ST-elevation myocardial infarction (STEMI)-ACS versus non-ST-elevation myocardial infarction (NSTEMI)-ACS]. RESULTS: In total, 4424 patients (2725 ticagrelor, 1699 prasugrel) were enrolled. After propensity-score matching, 1290 patients in each cohort were included in the analysis. At 12 months, the incidence of both NACE and MACE was lower with prasugrel (NACE: 5.3% vs. 8.5% [p = 0.001]; MACE: 5% vs. 8.1% [p =  0.001]) mainly driven by a reduction in recurrent myocardial infarction (MI) (2.4 vs. 4.0%; p = 0.029) and a lower rate of Bleeding Academic Research Consortium (BARC) 3-5 bleeding (1.5 vs. 2.9%; p = 0.011). The benefit of prasugrel was confirmed for patients with NSTEMI and for those discharged with a DAPT regimen of ≤ 12 months. Only a trend in the reduction of NACE and MACE was noted for STEMI or for those treated with longer DAPT. CONCLUSIONS: Comparison of these drugs suggested that prasugrel is safer and more efficacious than ticagrelor in combination with aspirin after NSTEMI but not STEMI. No differences were found for events occurring after 12 months. The nonrandomized design of the present research means further studies are required to support these findings

Prasugrel or ticagrelor in patients with acute coronary syndrome and diabetes: a propensity matched substudy of RENAMI

INTRODUCTION The safety and efficacy of prasugrel and ticagrelor in patients with diabetes mellitus presenting with acute coronary syndrome and treated with percutaneous coronary intervention remain to be assessed. METHODS All diabetes patients admitted for acute coronary syndrome and enrolled in the REgistry of New Antiplatelets in patients with Myocardial Infarction (RENAMI) were compared before and after propensity score matching. Net adverse cardiovascular events (composite of death, stroke, myocardial infarction and BARC 3-5 bleedings) and major adverse cardiovascular events (composite of death, stroke and myocardial infarction) were the co-primary endpoints. Single components of primary endpoints were secondary endpoints. RESULTS Among 4424 patients enrolled in RENAMI, 462 and 862 diabetes patients treated with prasugrel and ticagrelor, respectively, were considered. After propensity score matching, 386 patients from each group were selected. At 19±5 months, major adverse cardiovascular events and net adverse cardiovascular events were similar in the prasugrel and ticagrelor groups (5.4% vs. 3.4%, P=0.16 and 6.7% vs. 4.1%, P=0.11, respectively). Ticagrelor was associated with a lower risk of death and BARC 2-5 bleeding when compared to prasugrel (2.8% vs. 0.8%, P=0.031 and 6.0% vs. 2.6%, P=0.02, respectively) and a clear but not significant trend for a reduction of BARC 3-5 bleeding (2.3% vs. 0.8%, P=0.08). There were no significant differences in myocardial infarction recurrence and stent thrombosis. CONCLUSION Diabetes patients admitted for acute coronary syndrome seem to benefit equally in terms of major adverse cardiovascular events from ticagrelor or prasugrel use. Ticagrelor was associated with a significant reduction in all-cause death and bleedings, without differences in recurrent ischaemic events, which should be confirmed in dedicated randomised controlled trials
