Evolución de la asistencia cardiovascular en el Sistema Nacional de Salud de España. Datos del proyecto RECALCAR 2011-2020 / Trends in cardiovascular care in the National Health System in Spain. Data from the RECALCAR project 2011-2020

Introducción y objetivos: El proyecto RECALCAR (Recursos y Calidad en Cardiología), iniciativa de la Sociedad Española de Cardiología, pretende estandarizar la información para generar evidencia sobre los resultados en salud cardiovascular. Su objetivo es analizar la evolución de los recursos y la actividad de las unidades y los servicios de cardiología y conocer los resultados en la asistencia cardiovascular durante la última década en España. Métodos: Este estudio se basa en las dos fuentes anuales de datos del proyecto RECALCAR: una encuesta sobre recursos y actividad de las unidades y servicios de cardiología (2011-2020) y el conjunto mínimo básico de datos del Sistema Nacional de Salud (2011-2019), referido a insuficiencia cardiaca (IC), infarto agudo de miocardio con (IAMCEST) y sin (IAMSEST) elevación del segmento ST. Resultados: La encuesta incluye el 70% de las unidades y servicios de cardiología de España. Se ha observado una disminución en el número de camas de hospitalización y la estancia media y un incremento notable en el número de estudios de imagen cardiaca y procedimientos terapéuticos percutáneos. Los ingresos por IC ajustados por edad y sexo han disminuido, aunque su mortalidad y el porcentaje de reingresos han ido en aumento. La evolución de la mortalidad y los reingresos ha sido muy favorable en el IAMCEST; en el IAMSEST, aunque positiva, ha sido menos relevante. Conclusiones: La información aportada por el proyecto RECALCAR demuestra una evolución favorable en la última década en recursos, actividad y resultados en determinados procesos cardiovasculares y constituye una fuente esencial para mejoras futuras y facilitar la toma de decisiones en política sanitaria.

Introduction and objectives: The RECALCAR project (Resources and Quality in Cardiology), an initiative of the Spanish Society of Cardiology, aims to standardize information to generate evidence on cardiovascular health outcomes. The objective of this study was to analyze trends in the resources and activity of cardiology units and/or services and to identify the results of cardiovascular care during the last decade in Spain. Methods: The study was based on the 2 annual data sources of the RECALCAR project: a survey on resources and activity of cardiology units and/or services (2011-2020) and the minimum data set of the National Health System (2011-2019), referring to heart failure (HF), STEMI, and non-STEMI. Results: The survey included 70% of cardiology units and/or services in Spain. The number of hospital beds and length of stay decreased, while there was a notable increase in the number of cardiac imaging studies and percutaneous therapeutic procedures performed. Age- and sex-adjusted admissions for HF tended to decrease, despite an increase in mortality and the percentage of readmissions. In contrast, the trend in mortality and readmissions was highly favorable in STEMI; in non-STEMI, although positive, the trend was less marked. Conclusions: The information provided by the RECALCAR project shows a favorable trend in the last decade in resources, activity and results of certain cardiovascular processes and constitutes an essential source for future improvements and decision-making in health policy.

Mid-Term Angiographic and Intracoronary Imaging Results Following Intracoronary Lithotripsy in Calcified Coronary Artery Disease: Results From Two Tertiary Referral Centres.

BACKGROUND: Intracoronary lithotripsy (IVL) is a safe and effective treatment for coronary calcification. Angiographic and intracoronary imaging follow-up have not yet been described. We aimed to describe the mid-term angiographic outcomes following IVL. METHODS: Patients successfully treated with IVL in two tertiary referral hospitals were included. Repeat angiography and intracoronary imaging was performed. Quantitative coronary angiography (QCA) and optical coherence tomography (OCT) analyses were performed using dedicated workstations. RESULTS: Twenty patients were included; mean age 67.1 years, left anterior descending artery 55 %. Median IVL balloon size was 3.0 mm and a median of 60 pulses were delivered per vessel. Percentage stenosis by QCA was 60 % [IQR 51-70] reducing to 20 % post stenting (p < 0.001). On OCT, 88.9 % had circumferential calcium. IVL resulted in fractures in 88.9 %. Resulting minimum stent expansion was 91.75 % [IQR 81.5-108]. Follow-up was at a median of 22.7 months [IQR16.4-25.5]. Percentage stenosis by QCA was 22.5 % [IQR 14-30] and not significantly different from the index procedure (p > 0.05). Minimum stent expansion by OCT was 85 % [IQR 72-97]. Late luminal loss was 0.15 mm [IQR -0.25 to 0.69]. Binary angiographic instent restenosis (ISR) was 10 % (2 of 20 patients). OCT demonstrated a predominantly homogenous neointimal pattern with high backscatter. CONCLUSION: Following successful IVL treatment, repeat angiography demonstrated preserved stent parameters in the majority of patients with favorable vascular healing properties by OCT. A binary restenosis rate of 10 % was observed. These results suggest durable results following IVL treatment of severe coronary calcification however larger studies are warranted.

Vascular healing responses to paclitaxel coated balloons or everolimus eluting stents for the treatment of in-stent restenosis. Insights from optical coherence tomography.

BACKGROUND: Treatment of in-stent restenosis (ISR) remains a significant challenge. Current options include repeat stenting or drug-coated balloons. However, there is a paucity of data regarding vascular healing after these strategies. We, aimed to compare optical coherence tomography (OCT)-based vessel healing after treatment with paclitaxel-coated balloons (PCB) or everolimus-eluting stents (EES). METHODS: An OCT substudy (baseline and 6-9 months) of patients from RIBS IV and RIBS V, two prospective multicenter, randomized controlled clinical trials comparing PCB vs. EES in patients with ISR was performed. RESULTS: Sixty-four patients were included (30 PCB and 34 EES). There were no differences in the baseline or angiographic characteristics between groups. Both groups had the same proportion of drug-eluting and bare-metal stent (BMS) ISR. Baseline OCT analysis did not show differences in the qualitative characteristics of the ISR nor the restenotic tissue burden. Follow-up OCT showed a larger mean lumen area in the EES group (6.03 ± 1.5 vs. 5.24 ± 1.3 mm 2 ; P = 0.043) but no difference in angiographic restenosis ( P = 0.66). Percentage tissue coverage was higher with PCB vs. EES (26 ± 13 vs. 19 ± 11%; P = 0.031). EES-treated ISR more frequently had uncovered struts at follow-up [21 (72%) vs. 12 (44%); P = 0.034]. Tissue covering struts more frequently had a high backscatter structure after PCB [21 (78%) vs. 16 (55%); P = 0.07]. CONCLUSIONS: Compared with EES, ISR treated with PCB demonstrated more strut coverage with mainly high backscattering tissue. Larger OCT-defined neointimal proliferation in PCB-treated ISR did not translate into higher angiographic restenosis rates.

Chronic Oral Anticoagulation Therapy and Prognosis of Patients Admitted to Hospital for COVID-19: Insights from the HOPE COVID-19 Registry.

Background: Most evidence regarding anticoagulation and COVID-19 refers to the hospitalization setting, but the role of oral anticoagulation (OAC) before hospital admission has not been well explored. We compared clinical outcomes and short-term prognosis between patients with and without prior OAC therapy who were hospitalized for COVID-19. Methods: Analysis of the whole cohort of the HOPE COVID-19 Registry which included patients discharged (deceased or alive) after hospital admission for COVID-19 in 9 countries. All-cause mortality was the primary endpoint. Study outcomes were compared after adjusting variables using propensity score matching (PSM) analyses. Results: 7698 patients were suitable for the present analysis (675 (8.8%) on OAC at admission: 427 (5.6%) on VKAs and 248 (3.2%) on DOACs). After PSM, 1276 patients were analyzed (638 with OAC; 638 without OAC), without significant differences regarding the risk of thromboembolic events (OR 1.11, 95% CI 0.59-2.08). The risk of clinically relevant bleeding (OR 3.04, 95% CI 1.92-4.83), as well as the risk of mortality (HR 1.22, 95% CI 1.01-1.47; log-rank p value = 0.041), was significantly increased in previous OAC users. Amongst patients on prior OAC only, there were no differences in the risk of clinically relevant bleeding, thromboembolic events, or mortality when comparing previous VKA or DOAC users, after PSM. Conclusion: Hospitalized COVID-19 patients on prior OAC therapy had a higher risk of mortality and worse clinical outcomes compared to patients without prior OAC therapy, even after adjusting for comorbidities using a PSM. There were no differences in clinical outcomes in patients previously taking VKAs or DOACs. This trial is registered with NCT04334291/EUPAS34399.

Unplanned Hospital Readmissions After Transcatheter Aortic Valve Replacement in the Era of New-Generation Devices.

OBJECTIVES: Unplanned hospital readmissions after transcatheter aortic valve replacement (TAVR) are frequent and have been associated with a poor prognosis. We sought to determine the trends in the incidence and causes of unplanned hospital readmission after TAVR in patients receiving new-generation devices (NGDs) vs early-generation devices (EGDs). METHODS: The study population consisted of 1802 consecutive TAVR recipients (863 EGDs and 939 NGDs). Early and late readmissions were defined as those occurring ≤30 days and >30 days to 1-year post TAVR, respectively. RESULTS: A total of 986 unplanned hospital readmissions (cardiac cause, 38.4%; non-cardiac cause, 61.6%) were recorded at a median time of 110 days (interquartile range [IQR], 37-217) post TAVR. The rates of early (12.3% vs 9.4%; P=.046) and late (39.1% vs 31.6%; P<.01) readmission were lower in the NGD population. In the NGD group, major/life-threatening periprocedural bleeding (hazard ratio [HR], 2.40, 95% confidence interval [CI], 1.06-5.42; P=.04) and estimated glomerular filtration rate (eGFR) <60 mL/min at hospital discharge (HR, 1.80; 95% CI, 1.15-2.83; P=.01) were associated with an increased risk of early readmission post TAVR. Chronic obstructive pulmonary disease (HR, 1.42; 95% CI, 1.07-1.88; P=.02), eGFR <60 mL/min (HR, 1.43; 95% CI, 1.11-1.84; P<.01), and combining antiplatelet and anticoagulation therapy (HR, 1.37; 95% CI, 1.01-1.85; P=.04) determined an increased risk of late readmission. CONCLUSIONS: TAVR recipients receiving NGDs exhibited a significant but modest reduction in unplanned hospital readmissions, with about one-third of patients still requiring rehospitalization at 1-year follow-up in the contemporary TAVR era. Non-cardiac comorbidities, periprocedural bleeding events, and intensive antithrombotic therapy determined an increased risk.

Incidence, clinical impact and predictors of thrombocytopenia after transcatheter aortic valve replacement.

BACKGROUND: Thrombocytopenia is a common, yet poorly understood, complication after transcatheter aortic valve replacement (TAVR). Balloon-expandable transcatheter heart valve has been associated with higher incidence of thrombocytopenia, compared with self-expandable valves. The aim of this study was to analyze the incidence, clinical impact and predictors of acquired thrombocytopenia in patients undergoing TAVR. METHODS: We performed an observational study from consecutive patients with severe aortic stenosis undergoing TAVR (n = 679) in a single center. Association and best cut-off point of platelet decrease with early mortality was analyzed. Patients were classified according to postprocedural percentage decrease in platelet count (PDPC), comparing clinical outcomes and analyzing predictors of platelet decrease. RESULTS: The median PDPC was 37.1 [IQR: 27.4-46.9]. PDPC was associated with early mortality (OR: 2.1, 95%IC: 1.7-2.5 for each 10% decrease, AUC:0.81, 95%CI:0.72-0.89) with an optimal cut-off point of 46%. PDPC≥46% and late nadir (≥4 days) were both independent predictors of early mortality (OR: 6.0 [IQR: 2.4-14.9] and OR: 5.1 [IQR: 2.2-11.6], respectively). The combination of both factors (PDPC≥46% and nadir ≥4 day) was associated with higher 2-year mortality (55.7%) compared to an early significant nadir (PDPC≥46% and nadir <4 day, 28.9%) and non-significant nadir (PDPC<46%, 21.0%), p < 0.001. Independent predictors of PDPC≥46% were baseline platelet count, Portico™, Abbott valve, intraprocedural major vascular complication and residual aortic regurgitation ≥grade 2. CONCLUSION: The platelet count decreased almost 40% after TAVR. Late nadir and PDPC≥46% predicted short-term clinical outcomes. Concomitant late and significant platelet decrease was associated with mid-term mortality.

Amphilimus- vs. zotarolimus-eluting stents in patients with diabetes mellitus and coronary artery disease: the SUGAR trial.

AIM: Patients with diabetes mellitus are at high risk of adverse events after percutaneous revascularization, with no differences in outcomes between most contemporary drug-eluting stents. The Cre8 EVO stent releases a formulation of sirolimus with an amphiphilic carrier from laser-dug wells, and has shown clinical benefits in diabetes. We aimed to compare Cre8 EVO stents to Resolute Onyx stents (a contemporary polymer-based zotarolimus-eluting stent) in patients with diabetes. METHODS AND RESULTS: We did an investigator-initiated, randomized, controlled, assessor-blinded trial at 23 sites in Spain. Eligible patients had diabetes and required percutaneous coronary intervention. A total of 1175 patients were randomly assigned (1:1) to receive Cre8 EVO or Resolute Onyx stents. The primary endpoint was target-lesion failure, defined as a composite of cardiac death, target-vessel myocardial infarction, and clinically indicated target-lesion revascularization at 1-year follow-up. The trial had a non-inferiority design with a 4% margin for the primary endpoint. A superiority analysis was planned if non-inferiority was confirmed. There were 106 primary events, 42 (7.2%) in the Cre8 EVO group and 64 (10.9%) in the Resolute Onyx group [hazard ratio (HR): 0.65, 95% confidence interval (CI): 0.44-0.96; Pnon-inferiority < 0.001; Psuperiority = 0.030]. Among the secondary endpoints, Cre8 EVO stents had significantly lower rate than Resolute Onyx stents of target-vessel failure (7.5% vs. 11.1%, HR: 0.67, 95% CI: 0.46-0.99; P = 0.042). Probable or definite stent thrombosis and all-cause death were not significantly different between groups. CONCLUSION: In patients with diabetes, Cre8 EVO stents were non-inferior to Resolute Onyx stents with regard to target-lesion failure composite outcome. An exploratory analysis for superiority at 1 year suggests that the Cre8 EVO stents might be superior to Resolute Onyx stents with regard to the same outcome.

Vascular Injury After Stenting　- Insights of Systemic Mechanisms of Vascular Repair.

BACKGROUND: The role of circulating progenitor cells (CPC) in vascular repair following everolimus-eluting stent (EES) implantation is largely unknown. The aim of the study was to investigate the relationship between temporal variation in CPC levels following EES implantation and the degree of peri-procedural vascular damage, and stent healing, as measured by optical coherence tomography (OCT).Methods and Results: CPC populations (CD133+/KDR+/CD45low) included patients with stable coronary artery disease undergoing stent implantation, and were evaluated using a flow cytometry technique both at baseline and at 1 week. OCT evaluation was performed immediately post-implantation to quantify the stent-related injury and at a 9-month follow up to assess the mid-term vascular response. Twenty patients (mean age 66±9 years; 80% male) with EES-treated stenoses (n=24) were included in this study. Vascular injury score was associated with the 1-week increase of CD133+/KDR+/CD45low (ß 0.28 [95% CI 0.15; 0.41]; P<0.001) and with maximum neointimal thickness at a 9-month follow up (ß 0.008 [95% CI 0.0004; 0.002]; P=0.04). Inverse relationships between numbers of uncoated and apposed struts for the 9-month and the 1-week delta values of CD133+/KDR+/CD45low (ß -12.53 [95% CI -22.17; -2.90]; P=0.011), were also found. CONCLUSIONS: The extent of vessel wall injury influences early changes in the levels of CPC and had an effect on mid-term vascular healing after EES implantation. Early CPC mobilisation was associated with mid-term strut coverage.

Design and Rationale for a Real-World Prospective, Multicenter Registry of Myocardial Revascularization Failure and Secondary Revascularization: The REVASEC Study.

AIM: To investigate key aspects of the problem of myocardial revascularization failure (MRF) and repeat or secondary myocardial revascularization (SR) in contemporary practice. METHODS: The registry of secondary revascularization (REVASEC) is an investigator-initiated, multicenter, prospective registry enhanced with data monitoring and independent event adjudication (ClinicalTrials.govNCT03349385). It includes patients with prior revascularization referred to coronary angiography for suspected MRF with broad inclusion criteria. The main objectives are to describe the characteristics of patients with prior revascularization referred for repeat angiography, to describe and the rate and mechanisms of MRF (stent or graft failure, coronary artery disease progression or residual coronary artery disease); to evaluate the management including medical treatment and SR of these patients; and to assess the prognosis according to the outlined causative mechanisms. The registry has one year follow up for the primary endpoint (Patient-oriented composite endpoint including all-cause death, any myocardial infarction or any new unplanned revascularization according to subsets of MRF), but extended follow-up will be carried out up to 5 years. CONCLUSION: The REVASEC Registry will provide updated data on the characteristics, patterns of treatment, and 1-year outcomes of patients with MRF and SR in contemporary clinical practice.

Long-term outcomes after deferral of revascularization of in-stent restenosis using fractional flow reserve.

OBJECTIVES: To investigate the outcomes of deferred coronary revascularization in patients with non-significant in-stent restenosis (ISR) by physiological assessment. BACKGROUND: The pathophysiology and natural history of ISR is markedly different from de-novo stenoses. There is a paucity of data on the safety of deferral of revascularization of ISR using physiological assessment. METHODS: In this single centre study, using a propensity-score matched analysis, we compared the long-term clinical outcomes of patients with ISR and de-novo disease deferred based on intracoronary physiology. Matching was on a 1:2 basis of ISR to de-novo stenosis. The primary end point was major adverse cardiovascular events (MACE) a composite of all-cause mortality, target lesion revascularization or target vessel myocardial infarction at 36 months. RESULTS: Matched cohorts of 56 ISR and 112 de-novo stenoses were analyzed. The median percentage stenosis was 50% in both groups (p = 0.403). Deferral was based on fractional flow reserve (FFR). The mean FFR was 0.86 across both groups (p = 0.942). At 36-months, freedom from MACE was similar between groups; 86.2% versus 92.8% log rank p=0.180 for ISR and de-novo lesions, respectively. Neither were there differences in the individual components of MACE. CONCLUSIONS: Deferral of coronary revascularization in patients with ISR based on its functional impact is associated to similar long-term safety as in de-novo coronary stenosis.

Predictors of poor prognosis in healthy, young, individuals with SARS-CoV-2 infections.

OBJECTIVES: To identify predictors of poor prognosis in previously healthy young individuals admitted to hospital with coronavirus disease 2019 (COVID-19). METHODS: We studied a cohort of patients hospitalized with COVID-19. All patients without co-morbidities, without usual treatments and ≤65 years old were selected from an international registry (HOPE-COVID-19, NCT04334291). We focused on baseline variables-symptoms and signs at admission-to analyse risk factors for poor prognosis. The primary end point was a composite of major adverse clinical events during hospitalization including mortality, mechanical ventilation, high-flow nasal oxygen therapy, prone, sepsis, systemic inflammatory response syndrome and embolic events. RESULTS: Overall, 773 healthy young patients were included. The primary composite end point was observed in 29% (225/773) and the overall mortality rate was 3.6% (28/773). In the combined event group, 75% (168/225) of patients were men and the mean age was 49 (±11) years, whereas in the non-combined event group, the prevalence of male gender was 43% (238/548) and the mean age was 42 (±13) years (p < 0.001 for both). On admission, respiratory insufficiency and cough were described in 51.4% (114/222) and 76% (170/223) of patients, respectively, in the combined event group, versus 7.9% (42/533) and 56% (302/543) of patients in the other group (p < 0.001 for both). The strongest independent predictor for the combined end point was desaturation (Spo2 <92%) (OR 5.40; 95% CI 3.34-8.75; p < 0.001), followed by tachypnoea (OR 3.17; 95% CI 1.93-5.21; p < 0.001), male gender (OR 3.01; 95% CI 1.96-4.61; p < 0.001) and pulmonary infiltrates on chest X-ray at admission (OR 2.21; 95% CI 1.18-4.16; p 0.014). CONCLUSIONS: Major adverse clinical events were unexpectedly high considering the baseline characteristics of the cohort. Signs of respiratory compromise at admission and male gender, were predictive for poor prognosis among young healthy patients hospitalized with COVID-19.

Antiplatelet therapy and outcome in COVID-19: the Health Outcome Predictive Evaluation Registry.

BACKGROUND: Standard therapy for COVID-19 is continuously evolving. Autopsy studies showed high prevalence of platelet-fibrin-rich microthrombi in several organs. The aim of the study was therefore to evaluate the safety and efficacy of antiplatelet therapy (APT) in hospitalised patients with COVID-19 and its impact on survival. METHODS: 7824 consecutive patients with COVID-19 were enrolled in a multicentre international prospective registry (Health Outcome Predictive Evaluation-COVID-19 Registry). Clinical data and in-hospital complications were recorded. Data on APT, including aspirin and other antiplatelet drugs, were obtained for each patient. RESULTS: During hospitalisation, 730 (9%) patients received single APT (93%, n=680) or dual APT (7%, n=50). Patients treated with APT were older (74±12 years vs 63±17 years, p<0.01), more frequently male (68% vs 57%, p<0.01) and had higher prevalence of diabetes (39% vs 16%, p<0.01). Patients treated with APT showed no differences in terms of in-hospital mortality (18% vs 19%, p=0.64), need for invasive ventilation (8.7% vs 8.5%, p=0.88), embolic events (2.9% vs 2.5% p=0.34) and bleeding (2.1% vs 2.4%, p=0.43), but had shorter duration of mechanical ventilation (8±5 days vs 11±7 days, p=0.01); however, when comparing patients with APT versus no APT and no anticoagulation therapy, APT was associated with lower mortality rates (log-rank p<0.01, relative risk 0.79, 95% CI 0.70 to 0.94). On multivariable analysis, in-hospital APT was associated with lower mortality risk (relative risk 0.39, 95% CI 0.32 to 0.48, p<0.01). CONCLUSIONS: APT during hospitalisation for COVID-19 could be associated with lower mortality risk and shorter duration of mechanical ventilation, without increased risk of bleeding. TRIAL REGISTRATION NUMBER: NCT04334291.

Pre-dilation and Post-dilation in Transcatheter Aortic Valve Replacement: Indications, Benefits and Risks.

Transcatheter aortic valve replacement (TAVR) is an established treatment for patients with symptomatic severe aortic stenosis. In recent years, an emphasis has been placed on simplification of the procedure. Balloon predilation was initially considered a mandatory step to cross and prepare the stenotic aortic valve, but several studies demonstrated the feasibility of performing TAVR without balloon valvuloplasty. Balloon postdilation of the implanted valve is sometimes required to optimise results, although many patients do not require this step. Contemporary consensus advocates an individualised approach to TAVR procedures and so balloon pre- and post-dilation are performed selectively. This review aims to outline the advantages and disadvantages of balloon pre- and post-dilation and to identify the scenarios in which they are required during TAVR procedures.

Sepsis of Patients Infected by SARS-CoV-2: Real-World Experience From the International HOPE-COVID-19-Registry and Validation of HOPE Sepsis Score.

Background: Patients with sepsis with a concomitant coronavirus (COVID-19) infection are related to a high morbidity and mortality rate. We investigated a large cohort of patients with sepsis with a concomitant COVID-19, and we developed a risk score for the estimation of sepsis risk in COVID-19. Methods: We conducted a sub-analysis from the international Health Outcome Predictive Evaluation Registry for COVID-19 (HOPE-COVID-19-Registry, NCT04334291). Out of 5,837 patients with COVID-19, 624 patients were diagnosed with sepsis according to the Sepsis-3 International Consensus. Results: In multivariable analysis, the following risk factors were identified as independent predictors for developing sepsis: current smoking, tachypnoea (>22 breath per minute), hemoptysis, peripheral oxygen saturation (SpO2) <92%, blood pressure (BP) (systolic BP <90 mmHg and diastolic BP <60 mmHg), Glasgow Coma Scale (GCS) <15, elevated procalcitonin (PCT), elevated troponin I (TnI), and elevated creatinine >1.5 mg/dl. By assigning odds ratio (OR) weighted points to these variables, the following three risk categories were defined to develop sepsis during admission: low-risk group (probability of sepsis 3.1-11.8%); intermediate-risk group (24.8-53.8%); and high-risk-group (58.3-100%). A score of 1 was assigned to current smoking, tachypnoea, decreased SpO2, decreased BP, decreased GCS, elevated PCT, TnI, and creatinine, whereas a score of 2 was assigned to hemoptysis. Conclusions: The HOPE Sepsis Score including nine parameters is useful in identifying high-risk COVID-19 patients to develop sepsis. Sepsis in COVID-19 is associated with a high mortality rate.

Prevalence and 30-Day Mortality in Hospitalized Patients With Covid-19 and Prior Lung Diseases.

INTRODUCTION: Patients with pre-existing respiratory diseases in the setting of COVID-19 may have a greater risk of severe complications and even death. METHODS: A retrospective, multicenter, cohort study with 5847 COVID-19 patients admitted to hospitals. Patients were separated in two groups, with/without previous lung disease. Evaluation of factors associated with survival and secondary composite end-point such as ICU admission and respiratory support, were explored. RESULTS: 1,271 patients (22%) had a previous lung disease, mostly COPD. All-cause mortality occurred in 376 patients with lung disease (29.5%) and in 819 patients without (17.9%) (p < 0.001). Kaplan-Meier curves showed that patients with lung diseases had a worse 30-day survival (HR = 1.78; 95%C.I. 1.58-2.01; p < 0.001) and COPD had almost 40% mortality. Multivariable Cox regression showed that prior lung disease remained a risk factor for mortality (HR, 1.21; 95%C.I. 1.02-1.44; p = 0.02). Variables independently associated with all-cause mortality risk in patients with lung diseases were oxygen saturation less than 92% on admission (HR, 4.35; 95% CI 3.08-6.15) and elevated D-dimer (HR, 1.84; 95% CI 1.27-2.67). Age younger than 60 years (HR 0.37; 95% CI 0.21-0.65) was associated with decreased risk of death. CONCLUSIONS: Previous lung disease is a risk factor for mortality in patients with COVID-19. Older age, male gender, home oxygen therapy, and respiratory failure on admission were associated with an increased mortality. Efforts must be done to identify respiratory patients to set measures to improve their clinical outcomes.

INTRODUCCIÓN: Los pacientes con enfermedades respiratorias preexistentes pueden tener en el contexto de la covid-19 un mayor riesgo de complicaciones graves e incluso de muerte. MÉTODOS: Estudio de cohortes multicéntrico y retrospectivo de 5.847 pacientes con covid-19 ingresados en hospitales. Los pacientes se separaron en 2 grupos, sin y con enfermedad pulmonar previa. Se evaluaron factores asociados con la supervivencia y criterios combinados de valoración secundarios, como el ingreso en la UCI y la necesidad de asistencia respiratoria. RESULTADOS: Mil doscientos setenta y un (1.271) pacientes (22%) tenían una enfermedad pulmonar previa, principalmente EPOC. La mortalidad por todas las causas ocurrió en 376 pacientes con enfermedad pulmonar (29,5%) y en 819 pacientes sin enfermedad pulmonar (17,9%; p < 0,001). Las curvas de Kaplan-Meier mostraron que los pacientes con enfermedades pulmonares tenían una peor supervivencia a los 30 días (HR: 1,78; IC del 95%: 1,58-2,01; p < 0,001) y la EPOC tenía una mortalidad de casi el 40%. La regresión de Cox multivariante mostró que la enfermedad pulmonar previa seguía siendo un factor de riesgo de mortalidad (HR: 1,21; IC del 95%: 1,02-1,44; p = 0,02). Las variables asociadas de forma independiente con el riesgo de muerte por todas las causas en pacientes con enfermedades pulmonares fueron la saturación de oxígeno inferior al 92% al ingreso (HR: 4,35; IC del 95%: 3,08-6,15) y el dímero D elevado (HR: 1,84; IC del 95%: 1,27-2,67). La edad menor de 60 años (HR: 0,37; IC del 95%: 0,21-0,65) se asoció con una disminución del riesgo de muerte. CONCLUSIONES: La enfermedad pulmonar previa es un factor de riesgo de muerte en pacientes con covid-19. La edad avanzada, el sexo masculino, la oxigenoterapia domiciliaria y la insuficiencia respiratoria al ingreso se asociaron con un aumento de la mortalidad. Se deben realizar esfuerzos para identificar a los pacientes respiratorios y establecer medidas para mejorar sus resultados clínicos.

COVID-19 and the impact of arterial hypertension-An analysis of the international HOPE COVID-19 Registry (Italy-Spain-Germany).

BACKGROUND: A systematic analysis of concomitant arterial hypertension in COVID-19 patients and the impact of angiotensin-converting-enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARBs) have not been studied in a large multicentre cohort yet. We conducted a subanalysis from the international HOPE Registry (https://hopeprojectmd.com, NCT04334291) comparing COVID-19 in presence and absence of arterial hypertension. MATERIALS AND METHODS: Out of 5837 COVID-19 patients, 2850 (48.8%) patients had the diagnosis arterial hypertension. 1978/2813 (70.3%) patients were already treated with ACEI or ARBs. The clinical outcome of the present subanalysis included all-cause mortality over 40 days of follow-up. RESULTS: Patients with arterial hypertension suffered significantly more from different complications including respiratory insufficiency (60.8% vs 39.5%), heart failure (9.9% vs 3.1%), acute kidney injury (25.3% vs 7.3%), pneumonia (90.6% vs 86%), sepsis (14.7% vs 7.5%), and bleeding events (3.6% vs 1.6%). The mortality rate was 29.6% in patients with concomitant arterial hypertension and 11.3% without arterial hypertension (P < .001). Invasive and non-invasive respiratory supports were significantly more required in presence of arterial hypertension as compared without it. In the multivariate cox regression analysis, while age≥65, benzodiazepine, antidepressant at admission, elevated LDH or creatinine, respiratory insufficiency and sepsis might be a positive independent predictors of mortality, antiviral drugs, interferon treatment, ACEI or ARBs at discharge or oral anticoagulation at discharge might be an independent negative predictor of the mortality. CONCLUSIONS: The mortality rate and in-hospital complications might be increased in COVID-19 patients with a concomitant history of arterial hypertension. The history of ACEI or ARBs treatments does not seem to impact the outcome of these patients.

Impact of smoking on COVID-19 outcomes: a HOPE Registry subanalysis.

BACKGROUND: Smoking has been associated with poorer outcomes in relation to COVID-19. Smokers have higher risk of mortality and have a more severe clinical course. There is paucity of data available on this issue, and a definitive link between smoking and COVID-19 prognosis has yet to be established. METHODS: We included 5224 patients with COVID-19 with an available smoking history in a multicentre international registry Health Outcome Predictive Evaluation for COVID-19 (NCT04334291). Patients were included following an in-hospital admission with a COVID-19 diagnosis. We analysed the outcomes of patients with a current or prior history of smoking compared with the non-smoking group. The primary endpoint was all-cause in-hospital death. RESULTS: Finally, 5224 patients with COVID-19 with available smoking status were analysed. A total of 3983 (67.9%) patients were non-smokers, 934 (15.9%) were former smokers and 307 (5.2%) were active smokers. The median age was 66 years (IQR 52.0-77.0) and 58.6% were male. The most frequent comorbidities were hypertension (48.5%) and dyslipidaemia (33.0%). A relevant lung disease was present in 19.4%. In-hospital complications such sepsis (23.6%) and embolic events (4.3%) occurred more frequently in the smoker group (p<0.001 for both). All cause-death was higher among smokers (active or former smokers) compared with non-smokers (27.6 vs 18.4%, p<0.001). Following a multivariate analysis, current smoking was considered as an independent predictor of mortality (OR 1.77, 95% CI 1.11 to 2.82, p=0.017) and a combined endpoint of severe disease (OR 1.68, 95% CI 1.16 to 2.43, p=0.006). CONCLUSION: Smoking has a negative prognostic impact on patients hospitalised with COVID-19.

Managing the patient undergoing transcatheter aortic valve replacement with ongoing mitral regurgitation.

INTRODUCTION: Significant mitral regurgitation (MR) frequently coexists in patients with severe symptomatic aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). These patients have worse clinical outcomes than those with non-significant MR, especially if MR persists after treatment of the aortic stenosis. The optimal treatment approach for this challenging high-risk population is not well defined. AREAS COVERED: This review aims to present the current literature on concomitant significant MR in the TAVR population, and to provide a comprehensive algorithmic approach for clinical decision-making in this challenging cohort of patients. EXPERT OPINION: Concomitant mitral and aortic valve disease is a complex clinical entity. An exhaustive and comprehensive assessment of patient's clinical characteristics and mitral valve anatomy and function is required in order to assess the surgical risk, predict the MR response after AVR and evaluate the feasibility of percutaneous MV treatment if necessary. Further developments in transcatheter techniques will expand the indications for double valve treatment in operable and inoperable patients with concomitant significant MR and aortic stenosis.

Gender Differences in the Presentation and Outcomes of Hospitalized Patients With COVID-19.

Gender-related differences in COVID-19 clinical presentation, disease progression, and mortality have not been adequately explored. We analyzed the clinical profile, presentation, treatments, and outcomes of patients according to gender in the HOPE-COVID-19 International Registry. Among 2,798 enrolled patients, 1,111 were women (39.7%). Male patients had a higher prevalence of cardiovascular risk factors and more comorbidities at baseline. After propensity score matching, 876 men and 876 women were selected. Male patients more often reported fever, whereas female patients more often reported vomiting, diarrhea, and hyposmia/anosmia. Laboratory tests in men presented alterations consistent with a more severe COVID-19 infection (eg, significantly higher C-reactive protein, troponin, transaminases, lymphocytopenia, thrombocytopenia, and ferritin). Systemic inflammatory response syndrome, bilateral pneumonia, respiratory insufficiency, and renal failure were significantly more frequent in men. Men more often required pronation, corticosteroids, and tocilizumab administration. A significantly higher 30-day mortality was observed in men vs women (23.4% vs 19.2%; P = .039).
