BackgroundPatients with diabetes mellitus (DM) have an elevated risk of late events after percutaneous coronary intervention (PCI). The Second-generation Drug-eluting Stents in Diabetes (SUGAR) trial (NCT03321032) compared amphilimus-eluting stents (AESs) and onyx-zotarolimus-eluting stents (O-ZESs) in this population.ObjectivesTo report the co-primary endpoint comparing target lesion failure (TLF) between AES and O-ZES at 2 years and the extended follow-up at 3 years.MethodsThe SUGAR trial enrolled 1175 patients with DM across 23 centres in a randomised (1:1 AES (Cre8EVO) or O-ZES (Resolute Onyx)) assessor-blinded design. The primary endpoint, assessed with a Cox proportional hazards model, was TLF (a composite of cardiac death, target vessel myocardial infarction or ischaemia-driven target lesion revascularisation). Secondary endpoints included all-cause mortality, stent thrombosis and major adverse cardiac events.ResultsAt 2 years, TLF occurred in 60 (10.4%) patients in the AES group and 71 (12.1%) in the O-ZES group; HR 0.84 (95% CI 0.60 to 1.19), p=0.331. At 3 years, TLF occurred in 66 (11.4%) of the AES group compared with 87 (14.9%) of the O-ZES group (HR 0.77; 95% CI 0.56 to 1.06; p=0.106). Landmark analysis revealed no significant differences in TLF rates between 1 and 3 years (HR 1.07; 95% CI 0.62 to 1.87; p=0.801). Rates of individual components of the primary endpoint were comparable between groups. No significant differences were observed in secondary endpoints.ConclusionsThe SUGAR trial demonstrates that AES and O-ZES provide comparable long-term efficacy in preventing TLF in patients with DM undergoing PCI. These findings support the use of either stent type and highlight the importance of further long-term studies to optimise outcomes.Trial registration numberNCT03321032

Treatment of patients with drug-eluting stent (DES) in-stent restenosis (ISR) is particularly challenging. We sought to compare results of drug-eluting balloons in patients with DES-ISR with those in patients with bare-metal stent (BMS) ISR. A pooled analysis of the Restenosis Intra-Stent: Drug-Eluting Balloon versus Everolimus-Eluting Stent IV and V randomized trials was performed. Both trials had identical inclusion and exclusion criteria. Results of drug-eluting balloons in 95 patients with BMS-ISR and 154 patients with DES-ISR were compared. Patients with DES-ISR were more frequently diabetics, presented more often as an acute coronary syndrome and had more severe lesions and more frequently a focal pattern, including edge-ISR. Late angiographic findings (92% of eligible patients), including minimal lumen diameter (1.80 ± 0.6 vs 2.01 ± 0.6 mm, p = 0.001; absolute mean difference 0.21 mm; 95% confidence interval 0.04 to 0.38; p = 0.014) and restenosis rate (19% vs 9.5%, p <0.05) were poorer in DES-ISR. Results were consistent across 10 prespecified subgroups. Moreover, on multiple linear regression analysis, minimal lumen diameter at follow-up remained significantly smaller in patients with DES-ISR after adjusting for potential confounders (adjusted absolute mean difference 0.17 mm; 95% confidence interval 0.04 to 0.41; p = 0.019). Finally, at 1-year clinical follow-up (100% of patients), rates of target vessel revascularization (16% vs 6%, p = 0.02) and of the main combined clinical end point (18% vs 8%, p = 0.03) were significantly higher in patients treated for DES-ISR. In conclusion, this study confirms the efficacy of DEB for patients with ISR. However, the long-term clinical and angiographic results of DEB are poorer in patients with DES-ISR than in those with BMS-ISR. (ClinicalTrials.govIdentifier:NCT01239953&NCT01239940).

Discovery of new biomarkers is critical for early diagnosis of acute coronary syndrome (ACS). Recent advances in metabolomic technologies have drastically enhanced the possibility of improving the knowledge of its physiopathology through the identification of the altered metabolic pathways. In this study, analyses of peripheral plasma from non-ST segment elevation ACS patients and healthy controls by gas chromatography–mass spectrometry (GC–MC) permitted the identification of 15 metabolites with statistical differences ( p  < 0.05) between experimental groups. Additionally, validation by GC–MC and liquid chromatography–MC permitted us to identify a potential panel of biomarkers formed by 5-OH-tryptophan, 2-OH-butyric acid and 3-OH-butyric acid. This panel of biomarkers reflects the oxidative stress and the hypoxic state that suffers the myocardial cells and consequently constitutes a metabolomic signature of the atherogenesis process that could be used for early diagnosis of ACS.

Recently the coronavirus disease (COVID-19) outbreak has been declared a pandemic. Despite its aggressive extension and significant morbidity and mortality, risk factors are poorly characterized outside China. We designed a registry, HOPE COVID-19 (NCT04334291), assessing data of 1021 patients discharged (dead or alive) after COVID-19, from 23 hospitals in 4 countries, between 8 February and 1 April. The primary end-point was all-cause mortality aiming to produce a mortality risk score calculator. The median age was 68 years (IQR 52–79), and 59.5% were male. Most frequent comorbidities were hypertension (46.8%) and dyslipidemia (35.8%). A relevant heart or lung disease were depicted in 20%. And renal, neurological, or oncological disease, respectively, were detected in nearly 10%. Most common symptoms were fever, cough, and dyspnea at admission. 311 patients died and 710 were discharged alive. In the death-multivariate analysis, raised as most relevant: age, hypertension, obesity, renal insufficiency, any immunosuppressive disease, 02 saturation < 92% and an elevated C reactive protein (AUC = 0.87; Hosmer–Lemeshow test, p > 0.999; bootstrap-optimist: 0.0018). We provide a simple clinical score to estimate probability of death, dividing patients in four grades (I–IV) of increasing probability. Hydroxychloroquine (79.2%) and antivirals (67.6%) were the specific drugs most commonly used. After a propensity score adjustment, the results suggested a slight improvement in mortality rates (adjusted-ORhydroxychloroquine 0.88; 95% CI 0.81–0.91, p = 0.005; adjusted-ORantiviral 0.94; 95% CI 0.87–1.01; p = 0.115). COVID-19 produces important mortality, mostly in patients with comorbidities with respiratory symptoms. Hydroxychloroquine could be associated with survival benefit, but this data need to be confirmed with further trials. Trial Registration: NCT04334291/EUPAS34399.

Patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention (PCI) remain at high risk of cardiovascular events despite the use of contemporary drug-eluting stents (DES). This trial aim to compare the clinical efficacy of 2 novel second-generation DES in patients with DM. The Second-Generation Drug-Eluting Stents in Diabetes (SUGAR) trial (ClinicalTrials.gov NCT03321032) is an investigator-initiated, prospective, randomized, controlled, multicenter study conducted exclusively in patients with DM. This study allows inclusion of the entire spectrum of patients with DM undergoing PCI, and the only exclusion criteria are shock at presentation, inability to consent or a life expectancy <2 years. A total of 1164 patients will be randomized (1:1, no stratification) at 23 sites in Spain to treatment with polymer-free amphilimus (sirolimus formulated with an amphiphilic carrier) eluting stents versus Onyx-zotarolimus-eluting stents (Biolynx durable polymer and struts with platinum-iridium alloy core). Randomization will be patient-level, so in case of multivessel disease all lesions will be treated with the same stent. The primary end point is target lesion failure, a composite of cardiac death, target vessel–related myocardial infarction, or clinically indicated target lesion revascularization. First co-primary analysis will test non-inferiority at 1 year (80% power, a non-inferiority margin of 4% (1.5 RR) and a type-I-error of 0.05.) and second co-primary analysis will test superiority at 2 years (80% power, 0.05 alpha). Enrollment commenced in December 2017, and inclusion is expected to be completed by December 2019. SUGAR is the first randomized head-to head trial comparing second-generation DES in an all-comer diabetic population undergoing PCI.

Background During COVID-19 pandemic, elective invasive cardiac procedures (ICP) have been frequently cancelled or postponed. Consequences may be more evident in patients with diabetes. Objectives The objective was to identify the peculiarities of patients with DM among those in whom ICP were cancelled or postponed due to the COVID-19 pandemic, as well as to identify subgroups in which the influence of DM has higher impact on the clinical outcome. Methods We included 2,158 patients in whom an elective ICP was cancelled or postponed during COVID-19 pandemic in 37 hospitals in Spain. Among them, 700 (32.4%) were diabetics. Patients with and without diabetes were compared. Results Patients with diabetes were older and had a higher prevalence of other cardiovascular risk factors, previous cardiovascular history and co-morbidities. Diabetics had a higher mortality (3.0% vs. 1.0%; p = 0.001) and cardiovascular mortality (1.9% vs. 0.4%; p = 0.001). Differences were especially important in patients with valvular heart disease (mortality 6.9% vs 1.7% [p < 0.001] and cardiovascular mortality 4.9% vs 0.9% [p = 0.002] in patients with and without diabetes, respectively). In the multivariable analysis, diabetes remained as an independent risk factor both for overall and cardiovascular mortality. No significant interaction was found with other clinical variables. Conclusion Among patients in whom an elective invasive cardiac procedure is cancelled or postponed during COVID-19 pandemic, mortality and cardiovascular mortality is higher in patients with diabetes, irrespectively on other clinical conditions. These procedures should not be cancelled in patients with diabetes.

We sought to explore the immediate clinical and angiographic results of the Titan ® stent implantation in diabetic patients, as well as the major adverse cardiac events (MACE) at 6-month follow-up. We enrolled 156 consecutive diabetic patients admitted to undergo percutaneous intervention for at least one significant (50%) coronary lesion. All lesions were treated with the Titan ® stent implantation according to the contemporary interventional techniques. Patients were prospectively followed-up for at least 6 months. The primary endpoint was MACE at 6-month follow-up [cardiac death, myocardial infarction (MI), or target lesion revascularization (TLR)]. Secondary endpoints included angiographic and clinical procedural success, in-hospital MACE, TLR at 6-month follow-up, and stent thrombosis. The mean age was 66.7 ± 9.6 years, (68.4% males). A total of 197 Titan ® stents were implanted in 163 lesions. Direct stenting was performed in 45.2% of the cases. The mean stent diameter was 3.1 ± 0.61 mm, and the mean length was 18.0 ± 8.9 mm. Average stent deployment pressure was 13.9 ± 4.2 bars. Angiographic procedural success was achieved in 154 (98.7%) cases, and clinical procedural success was achieved in 153 (98.1%) cases. One patient developed in-hospital non-Q-wave MI following the procedure. Clinical follow-up was completed in 155 (99.4%) patients. Three patients (1.9%) died of a cardiac or unknown cause, and two (1.3%) developed MI. TLR was performed in 11 patients (7.1%). Cumulative MACE at 6-month follow-up occurred in 16 (10.3%) patients. No patient suffered stent thrombosis. Titan ® stent implantation in diabetic patients achieves an excellent immediate clinical and angiographic outcome, with a low incidence of MACE at mid-term follow-up.

Background Acute coronary syndrome is the major cause of death in developed countries. Despite its high prevalence, there is still a strong need for new biomarkers which permit faster and more accurate diagnostics and new therapeutic drugs. The basis for this challenge lay in improving our understanding of the whole atherosclerotic process from atherogenesis to atherothrombosis. In this study, we conducted two different proteomic analyses of peripheral blood plasma from non-ST elevation acute coronary syndrome and ST elevation acute coronary syndrome patients vs healthy controls. Results Two-dimensional Fluorescence Difference in Gel Electrophoresis and mass spectrometry permitted the identification of 31 proteins with statistical differences (p < 0.05) between experimental groups. Additionally, validation by Western blot and Selected Reaction Monitoring permitted us to confirm the identification of a different and characteristic plasma proteomic signature for NSTEACS and STEACS patients. Conclusions We purpose the severity of hypoxia as the cornerstone for explaining the differences observed between both groups.

Mango cultivation in Colombia faces the impact of regional climate variability. To improve fruit development and minimize environmental and economic effects, it is necessary to implement efficient irrigation and appropriate water management technologies. In this study, we developed a trend forecasting system based on an LSTM neural network and technologies such as ThingsBoard, LoRA, and MQTT. The aim was to improve mango irrigation practices through informed decisions based on monitoring and predicting matric potential and evapotranspiration variables. This article describes the development and application of the system for mango irrigation management. Results validate the effectiveness of the proposed system for mango cultivation, with RMSE indices of 1.56 and 0.0019 and determination coefficients (R2) of 0.9989 and 0.9971 for matric potential and evapotranspiration, respectively. These findings support enhancing growth conditions and promoting sustainable practices. Despite data availability limitations, the system's efficacy in prediction and irrigation management demonstrates significant potential to maximize productivity and reduce the environmental and economic impacts of inadequate water management.

Evidence regarding therapy with drug-eluting stents in the left main coronary artery (LM) is based mostly on trials performed with first-generation drug-eluting stents. The aim of this study was to evaluate long-term clinical outcomes after treatment for unprotected LM disease with paclitaxel-eluting stents (PES) and everolimus-eluting stents (EES). The ESTROFA-LM is a multicenter retrospective registry including consecutive patients with unprotected LM disease treated with PES or EES. A total of 770 patients have been included at 21 centers, 415 with treated PES and 355 with EES. Treatment with 2 stents was more frequent with PES (17% vs 10.4%, p = 0.007), whereas intravascular ultrasound was more frequently used with EES (35.2% vs 26%, p = 0.006). The 3-year death and infarction survival rates were 86.1% for PES and 87.3% for EES (p = 0.50) and for death, infarction, and target lesion revascularization were 83.6% versus 82% (p = 0.60), respectively. Definite or probable thrombosis was 1.6% for PES and 1.4% for EES (p = 0.80). The use of 2 stents, age, diabetes, and acute coronary syndromes were independent predictors of mortality. In the subgroup of distal lesions, the use of intravascular ultrasound was an independent predictor of better outcome. Comparison of propensity score–matched groups did not yield differences between the 2 stents. In conclusion, the results of this multicenter registry show comparable safety and efficacy at 3 years for PES and EES in the treatment of LM disease. The use of bifurcation stenting techniques in distal lesions was a relevant independent predictor for events. The use of intravascular ultrasound appears to have a positive impact on patients treated for LM distal disease.
