Treatment with SGLT2 Inhibitors in Patients with Diabetes Mellitus and Extensive Coronary Artery Disease: Mortality and Cardiovascular Outcomes.

INTRODUCTION: Sodium-glucose type 2 cotransporter inhibitors (SGLT2-I) have shown solid benefits in reducing cardiovascular mortality and admissions for heart failure in patients with type 2 diabetes mellitus (T2DM) and cardiovascular disease. However, no specific studies exist in patients with high-risk coronary artery disease (CAD). METHODS: Single-center, retrospective, observational study including patients with T2DM and a new diagnosis of extensive CAD (defined as left main disease or three main coronary vessel disease). Patients were recruited from 2015 until 2020, with a follow-up of at least 12 months. The primary outcome was to compare all-cause mortality in patients treated with or without SGLT2-I at discharge and adjusted by inverse probability of treatment weighting (IPTW) propensity score. RESULTS: A total of 420 patients were included: 104 (24.7%) were treated with SGLT2-I and 316 (75.3%) were not (non-SGLT2-I group). The presentation was acute coronary syndrome in 44.3%. The mean age was 71.2 ± 10.5 years. The mean left ventricular ejection fraction was 51.5 ± 12.5%, and the mean estimated glomerular filtration rate was 73.9 ± 22 ml/min. After a mean follow-up of 3 ± 1.6 years, all-cause mortality was 16.4%, and cardiovascular mortality was 9.5%. After IPTW, the risk of all-cause death was lower in the SGLT2-I group with a hazard ratio of 0.32 (95% confidence interval 0.12-0.81), p = 0.016. With regard to secondary outcomes, patients in the SGLT2-I group were associated with less renal function deterioration but an increase in unplanned revascularizations. CONCLUSIONS: In patients with T2DM and extensive CAD, treatment with SGLT2-I after discharge was associated with a reduced risk of all-cause death.

Association between hormone therapy and short-term cardiovascular events in women with spontaneous coronary artery dissection.

INTRODUCTION AND OBJECTIVES: Changes in sex hormone levels are a known triggering factor for spontaneous coronary artery dissection (SCAD) in women. However, it is unknown whether exposure to exogenous hormone therapy (HT) at the time of SCAD presentation modifies the clinical course of this condition. We investigated the association between HT in female patients presenting with SCAD and short-term clinical outcomes. METHODS: We enrolled consecutive patients presenting with SCAD from the DISCO-IT/SPA (dissezioni spontanee coronariche Italian-Spanish) registry. Women on HT (estrogens, progestagens, or gonadotropins) at the time of presentation were identified, and their clinical characteristics and short-term outcomes were compared with those not receiving active HT. The outcome measure was nonfatal myocardial infarction and/or unplanned percutaneous coronary intervention during the first 28 days after the index catheterization. RESULTS: Of 224 women presenting with SCAD (mean age 52.0±10.0 years), 39 (17.4%) were currently using HT while 185 (82.6%) were not. No significant differences were noted in the baseline demographics, clinical presentation, angiographic features, or initial treatment received between the 2 groups. All patients on systemic HT (n=36, 92%) discontinued it at the time of diagnosis. The composite outcome occurred in 7 (17.9%) patients with prior HT compared with 14 (7.6%) without (P=.039). After multivariable adjustment, HT remained associated with the composite outcome recorded in the first 28 days of follow-up (HR, 3.53; 95%CI, 1.30-9.61; P=.013). CONCLUSIONS: In women with SCAD, exposure to HT at the time of clinical presentation was associated with short-term recurrent cardiovascular events such as nonfatal myocardial infarction and/or unplanned percutaneous revascularization.

Effects of intravenous lysine acetylsalicylate versus oral aspirin on platelet responsiveness in patients with ST-segment elevation myocardial infarction: the ECCLIPSE-STEMI trial.

Prasugrel and ticagrelor, new P2Y12-ADP receptor antagonists, are associated with greater pharmacodynamic inhibition and reduction of cardiovascular events in patients with an acute coronary syndrome. However, evidence is lacked about the effects of achieving faster and stronger cyclooxygenase inhibition with intravenous lysine acetylsalicylate (LA) compared to oral aspirin. Recently, we demonstrated in healthy volunteers that the administration of intravenous LA resulted in a significantly reduction of platelet reactivity compared to oral aspirin. Loading dose of LA achieves platelet inhibition faster, and with less variability than aspirin. However, there are no data of this issue in patients with an ST-segment elevation myocardial infarction (STEMI). This is a prospective, randomized, multicenter, open platelet function study conducted in STEMI patients. Subjects were randomly assigned to receive a loading dose (LD) of intravenous LA 450 mg plus oral ticagrelor 180 mg, or LD of aspirin 300 mg plus ticagrelor 180 mg orally. Platelet function was evaluated at baseline, 30 min, 1 h, 4 h and 24 h using multiple electrode aggregometry and vasodilator-stimulated phosphoprotein phosphorylation (VASP). The primary endpoint of the study is the inhibition of platelet aggregation (IPA) after arachidonic acid (AA) 0.5 mM at 30 min. Secondary endpoints were the IPA at 1, 4, and 24 h after AA, and non-AA pathways through the sequence (ADP and TRAP). A total of 32 STEMI patients were randomized (16 LA, 16 aspirin). The inhibition of platelet aggregation after AA 0.5 mM at 30 min was greater in subjects treated with LA compared with aspirin: 166 vs. 412 respectively (p = 0.001). This differential effect was observed at 1 h (p = 0.01), but not at 4 and 24 h. Subjects treated with LA presented less variability and faster inhibition of platelet aggregation wit AA compared with aspirin. The administration of intravenous LA resulted in a significantly reduction of platelet reactivity compared to oral aspirin on ticagrelor inhibited platelets in patients with STEMI. Loading dose of LA achieves an earlier platelet inhibition, and with less variability than aspirin.Trial Registration: Unique identifier: NCT02929888; URL: http://www.clinicaltrials.gov.

Polypill Strategy in Secondary Cardiovascular Prevention.

BACKGROUND: A polypill that includes key medications associated with improved outcomes (aspirin, angiotensin-converting-enzyme [ACE] inhibitor, and statin) has been proposed as a simple approach to the secondary prevention of cardiovascular death and complications after myocardial infarction. METHODS: In this phase 3, randomized, controlled clinical trial, we assigned patients with myocardial infarction within the previous 6 months to a polypill-based strategy or usual care. The polypill treatment consisted of aspirin (100 mg), ramipril (2.5, 5, or 10 mg), and atorvastatin (20 or 40 mg). The primary composite outcome was cardiovascular death, nonfatal type 1 myocardial infarction, nonfatal ischemic stroke, or urgent revascularization. The key secondary end point was a composite of cardiovascular death, nonfatal type 1 myocardial infarction, or nonfatal ischemic stroke. RESULTS: A total of 2499 patients underwent randomization and were followed for a median of 36 months. A primary-outcome event occurred in 118 of 1237 patients (9.5%) in the polypill group and in 156 of 1229 (12.7%) in the usual-care group (hazard ratio, 0.76; 95% confidence interval [CI], 0.60 to 0.96; P = 0.02). A key secondary-outcome event occurred in 101 patients (8.2%) in the polypill group and in 144 (11.7%) in the usual-care group (hazard ratio, 0.70; 95% CI, 0.54 to 0.90; P = 0.005). The results were consistent across prespecified subgroups. Medication adherence as reported by the patients was higher in the polypill group than in the usual-care group. Adverse events were similar between groups. CONCLUSIONS: Treatment with a polypill containing aspirin, ramipril, and atorvastatin within 6 months after myocardial infarction resulted in a significantly lower risk of major adverse cardiovascular events than usual care.

Effects of a comprehensive lifestyle intervention on cardiovascular health: the TANSNIP-PESA trial.

AIMS: To investigate the effectiveness of a 3-year worksite lifestyle intervention on cardiovascular metrics and to study whether outcomes are influenced by baseline subclinical atherosclerosis (SA) by non-invasive imaging. METHODS AND RESULTS: A randomized controlled trial was performed to compare a lifestyle intervention with standard of care in asymptomatic middle-aged subjects, stratified by SA. The intervention consisted of nine motivational interviews during the first year, followed by three further sessions between Years 1 and 3. The primary outcome was the change in a pre-specified adaptation of the Fuster-BEWAT score (Blood pressure, Exercise, Weight, Alimentation, and Tobacco) between baseline and follow-up Years 1-3. A total of 1020 participants (mean age 50 ± 4 years) were enrolled, of whom 510 were randomly assigned to the intervention and 510 to the control group. The baseline adapted Fuster-BEWAT score was 16.2 ± 3.7 points in the intervention group and 16.5 ± 3.5 points in the control group. At Year 1, the score improved significantly in intervention participants compared with controls [estimate 0.83 (95% CI 0.52-1.15) points]. However, intervention effectiveness decreased to non-significant levels at Year 3 [0.24 (95% CI -0.10 to 0.59) points]. Over the 3-year period, the intervention was effective in participants having low baseline SA [0.61 (95% CI 0.30-0.93) points] but not in those with high baseline SA [0.19 (95% CI -0.26 to 0.64) points]. CONCLUSION: In middle-aged asymptomatic adults, a lifestyle intervention was associated with a significant improvement in cardiovascular health and behavioural metrics. The effect attenuated after 1 year as the intensity of the intervention was reduced. TRIAL REGISTRATION: ClinicalTrials.gov (NCT02561065).

Bone marrow activation in response to metabolic syndrome and early atherosclerosis.

AIMS: Experimental studies suggest that increased bone marrow (BM) activity is involved in the association between cardiovascular risk factors and inflammation in atherosclerosis. However, human data to support this association are sparse. The purpose was to study the association between cardiovascular risk factors, BM activation, and subclinical atherosclerosis. METHODS AND RESULTS: Whole body vascular 18F-fluorodeoxyglucose positron emission tomography/magnetic resonance imaging (18F-FDG PET/MRI) was performed in 745 apparently healthy individuals [median age 50.5 (46.8-53.6) years, 83.8% men] from the Progression of Early Subclinical Atherosclerosis (PESA) study. Bone marrow activation (defined as BM 18F-FDG uptake above the median maximal standardized uptake value) was assessed in the lumbar vertebrae (L3-L4). Systemic inflammation was indexed from circulating biomarkers. Early atherosclerosis was evaluated by arterial metabolic activity by 18F-FDG uptake in five vascular territories. Late atherosclerosis was evaluated by fully formed plaques on MRI. Subjects with BM activation were more frequently men (87.6 vs. 80.0%, P = 0.005) and more frequently had metabolic syndrome (MetS) (22.2 vs. 6.7%, P < 0.001). Bone marrow activation was significantly associated with all MetS components. Bone marrow activation was also associated with increased haematopoiesis-characterized by significantly elevated leucocyte (mainly neutrophil and monocytes) and erythrocyte counts-and with markers of systemic inflammation including high-sensitivity C-reactive protein, ferritin, fibrinogen, P-selectin, and vascular cell adhesion molecule-1. The associations between BM activation and MetS (and its components) and increased erythropoiesis were maintained in the subgroup of participants with no systemic inflammation. Bone marrow activation was significantly associated with high arterial metabolic activity (18F-FDG uptake). The co-occurrence of BM activation and arterial 18F-FDG uptake was associated with more advanced atherosclerosis (i.e. plaque presence and burden). CONCLUSION: In apparently healthy individuals, BM 18F-FDG uptake is associated with MetS and its components, even in the absence of systemic inflammation, and with elevated counts of circulating leucocytes. Bone marrow activation is associated with early atherosclerosis, characterized by high arterial metabolic activity. Bone marrow activation appears to be an early phenomenon in atherosclerosis development.[Progression of Early Subclinical Atherosclerosis (PESA); NCT01410318].

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.

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.

Underlying heart diseases and acute COVID-19 outcomes.

BACKGROUND: The presence of any underlying heart condition could influence outcomes during the coronavirus disease 2019 (COVID-19). METHODS: The registry HOPE-COVID-19 (Health Outcome Predictive Evaluation for COVID-19, NCT04334291) is an international ambispective study, enrolling COVID-19 patients discharged from hospital, dead or alive. RESULTS: HOPE enrolled 2798 patients from 35 centers in 7 countries. Median age was 67 years (IQR: 53.0-78.0), and most were male (59.5%). A relevant heart disease was present in 682 (24%) cases. These were older, more frequently male, with higher overall burden of cardiovascular risk factors (hypertension, dyslipidemia, diabetes mellitus, smoking habit, obesity) and other comorbidities such renal failure, lung, cerebrovascular disease and oncologic antecedents (p < 0.01, for all). The heart cohort received more corticoids (28.9% vs. 20.4%, p < 0.001), antibiotics, but less hydroxychloroquine, antivirals or tocilizumab. Considering the epidemiologic profile, a previous heart condition was independently related with shortterm mortality in the Cox multivariate analysis (1.62; 95% CI 1.29-2.03; p < 0.001). Moreover, heart patients needed more respiratory, circulatory support, and presented more in-hospital events, such heart failure, renal failure, respiratory insufficiency, sepsis, systemic infammatory response syndrome and clinically relevant bleedings (all, p < 0.001), and mortality (39.7% vs. 15.5%; p < 0.001). CONCLUSIONS: An underlying heart disease is an adverse prognostic factor for patients suffering COVID-19. Its presence could be related with different clinical drug management and would benefit from maintaining treatment with angiotensin converting enzyme inhibitors or angiotensin receptor blockers during in-hospital stay.

Dose-reducing fluoroscopic system decreases patient but not occupational radiation exposure in chronic total occlusion intervention.

AIMS: Several novel low-dose fluoroscopic systems (LDS) developed recently, but real practice information of the net benefit for the patient and professionals is scarce. We evaluated separately patient and operator radiation exposure during percutaneous interventions of chronic total occlusions (CTO). METHODS: A total of 116 consecutive CTOs were analyzed (60 in LDS and 56 in standard-dose fluoroscopic system [SDS]). Digital dosimetry of patient and occupational (operator and scatter dose) exposure was prospectively recorded. RESULTS: Biometrics, demographics, CTO variables, and operators were distributed evenly. Patient radiation exposure was effectively decreased in LDS (dose area product [DAP] by 36%, Air Kerma [AK] by 47%). However, occupational data showed no statistical differences between LDS and SDS. The LDS uses less radiation amount but with higher energy (due to additional filtration) compared to SDS, therefore increasing the scatter dose. When comparing the C-arm scatter dose to the DAP we found higher scatter dose with the LDS (0.0139 mSv/gray (Gy)*cm2 vs. 0.0082 mSv/Gy*cm2, p < .001). This was confirmed in a larger dataset comprising 5,221 coronary procedures. CONCLUSIONS: LDS was safer for patients reducing DAP and AK compared to SDS. However, occupational doses were not lower and scatter dose higher. Radiological protection measures must be kept maximized even in LDS.

Mortality risk assessment in Spain and Italy, insights of the HOPE COVID-19 registry.

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.

Performance of the heart team approach in daily clinical practice in high-risk patients with aortic stenosis.

OBJECTIVE: The heart team (HT) approach plays a key role in selecting the optimal treatment strategy for patients with aortic stenosis (AS). However, little is known about the HT decision process and its impact on outcomes. The aim of this study was to identify the factors associated with the HT decision and evaluate clinical outcomes according to the treatment choice. METHODS: The study included a total of 286 consecutive patients with AS referred for discussion in the weekly HT meeting in a cardiovascular institute over 2 years. Patients were stratified according to the selected therapeutic approach: medical treatment (MT), surgical (SAVR), or transcatheter (TAVR) aortic valve replacement. Baseline characteristics involved in making a therapeutic choice were identified and a decision-making tree was built using classification and regression tree methodology. RESULTS: Based on HT discussion, 53 patients were assigned to SAVR, 210 to TAVR, and 23 to MT. Older patients (≥88 years old) were mainly assigned to TAVR or MT according to the logistic EuroSCORE (

Interaction between age and vitamin D deficiency in severe COVID-19 infection.

INTRODUCTION: Background: coronavirus disease 2019 (COVID-19) can induce an exaggerated inflammatory response. Vitamin D is a key modulator of the immune system. We hypothesized that vitamin D deficiency (VDD) could increase the risk of developing severe COVID-19 infection. Methods: patients with confirmed COVID-19 seen at the emergency department of our hospital with recent measurements of 25(OH)D were recruited. We explored the association of vitamin D deficiency (VDD), defined as 25-hydroxyvitamin D < 20 ng/mL, with a composite of adverse clinical outcomes. Results: we included 80 patients, of which 31 (39 %) presented the endpoint. VDD tended to predict an increased risk of developing severe COVID-19 after adjusting for age, gender, obesity, cardiac disease, and kidney disease [OR 3.2 (95 % CI: 0.9-11.4), p = 0.07]. Age had a negative interaction with the effect of VDD on the composite outcome (p = 0.03), indicating that the effect was more noticeable at younger ages. Furthermore, male gender was associated with VDD and with severe COVID-19 at younger ages. Conclusions: in this retrospective study, vitamin D deficiency showed a signal of association with severe COVID-19 infection. A significant interaction with age was noted, suggesting VDD may have a greater impact in younger patients. These findings should be confirmed in larger, prospective, adequately powered studies.

INTRODUCCIÓN: Antecedentes: la enfermedad por coronavirus 2019 (COVID-19) puede inducir una respuesta inflamatoria exagerada. La vitamina D es un modulador clave del sistema inmune. Planteamos que la deficiencia de vitamina D (VDD) podría aumentar el riesgo de desarrollar infección grave por COVID-19. Métodos: se reclutaron pacientes consecutivos que acudieron al servicio de urgencias de nuestro centro con diagnóstico de COVID-19 confirmado (PCR-COVID-19 positiva) y mediciones recientes de 25(OH)D. Exploramos la asociación de la deficiencia de vitamina D (VDD), definida como una 25-hidroxivitamina D < 20 ng/ml, con un compuesto de resultados clínicos adversos. Resultados: se incluyeron 80 pacientes, de los cuales 31 (39 %) presentaron el criterio de valoración primario. El VDD tendió a predecir un mayor riesgo de desarrollar COVID-19 grave después de ajustar edad, sexo, obesidad, enfermedad cardíaca y enfermedad renal [OR: 3,2 (IC 95 %: 0,9-11,4), p = 0,07]. La edad tuvo una interacción negativa con el efecto de la VDD en el resultado compuesto (p = 0,03), lo que indica que el efecto fue más notable a edades más tempranas. Además, el género masculino se asoció con la VDD y con la COVID-19 grave en las edades más jóvenes. Conclusiones: en este estudio retrospectivo, la deficiencia de vitamina D mostró una tendencia de asociación con la infección grave por COVID-19. Se observó una interacción significativa con la edad, lo que sugiere que la VDD puede tener un mayor impacto en los pacientes más jóvenes. Estos hallazgos deben confirmarse en estudios más grandes, prospectivos y con potencia adecuada.

Impact of renal function on admission in COVID-19 patients: an analysis of the international HOPE COVID-19 (Health Outcome Predictive Evaluation for COVID 19) Registry.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite its international aggressive extension, with a significant morbidity and mortality, the impact of renal function on its prognosis is uncertain. METHODS: Analysis from the international HOPE-Registry (NCT04334291). The objective was to evaluate the association between kidney failure severity on admission with the mortality of patients with SARS-CoV-2 infection. Patients were categorized in 3 groups according to the estimated glomerular filtration rate on admission (eGFR > 60 mL/min/1.73 m2, eGFR 30-60 mL/min/1.73 m2 and eGFR < 30 mL/min/1.73 m2). RESULTS: 758 patients were included: mean age was 66 ± 18 years, and 58.6% of patient were male. Only 8.5% of patients had a history of chronic kidney disease (CKD); however, 30% of patients had kidney dysfunction upon admission (eGFR < 60 mL/min/1.73 m2). These patients received less frequently pharmacological treatment with hydroxychloroquine or antivirals and had a greater number of complications such as sepsis (11.9% vs 26.4% vs 40.8%, p < 0.001) and respiratory failure (35.4% vs 72.2% vs 62.0%, p < 0.001) as well as a higher in-hospital mortality rate (eGFR > 60 vs eGFR 30-60 vs and eGFR < 30, 18.4% vs 56.5% vs 65.5%, p < 0.001). In multivariate analysis: age, hypertension, renal function, 02 saturation < 92% and lactate dehydrogenase elevation on admission independently predicted all-cause mortality. CONCLUSIONS: Renal failure on admission in patients with SARS-CoV-2 infection is frequent and is associated with a greater number of complications and in-hospital mortality. Our data comes from a multicenter registry and therefore does not allow to have a precise mortality risk assessment. More studies are needed to confirm these findings.

Short-Term Progression of Multiterritorial Subclinical Atherosclerosis.

BACKGROUND: Atherosclerosis progression predicts cardiovascular events; however, progression of multiterritorial subclinical atherosclerosis is incompletely understood. OBJECTIVES: This study sought to study short-term progression of atherosclerosis using different noninvasive imaging techniques and their relationship with cardiovascular risk. METHODS: The study included 3,514 PESA (Progression of Early Subclinical Atherosclerosis) study participants (45.7 ± 4.2 years of age; 63% men). Participants underwent 2-dimensional vascular ultrasound (2DVUS) of abdominal aorta, carotid, iliac, and femoral territories to determine a plaque number score; 3DVUS to quantify carotid and femoral plaque volume; and coronary artery calcium score (CACS) at baseline and 2.8 years later. The authors calculated the rate of new disease incidence and changes in disease extent. Logistic regression models were used to evaluate associations of progression rates with baseline cardiovascular risk factors and estimated 10-year risk. RESULTS: Imaging detected short-term (3-year) atherosclerosis progression in 41.5% of participants (26.4% by 2DVUS, 21.3% by 3DVUS, and 11.5% by CACS), particularly in peripheral territories examined by vascular ultrasound. New atherosclerosis onset accounted for approximately one-third of total progression, also more frequently by 2DVUS and 3DVUS (29.1% and 16.6%, respectively), than by CACS (2.9%). Participants with baseline disease by all 3 modalities (n = 432) also showed significant atherosclerosis progression (median: 1 plaque [interquartile range (IQR): -1 to 3 plaques] by 2DVUS; 7.6 mm3 [IQR: -32.2 to 57.6 mm3] by 3DVUS; and 21.6 Agatston units [IQR: 4.8 to 62.6 Agatston units] by CACS). Age, sex, dyslipidemia, hypertension, smoking, and family history of premature cardiovascular disease contributed to progression, with dyslipidemia the strongest modifiable risk factor. Although disease progression correlated with cardiovascular risk, progression was detected in 36.5% of participants categorized as low risk. CONCLUSIONS: With this multimodal and multiterritorial approach, the authors detected short-term progression of early subclinical atherosclerosis in a substantial proportion (41.5%) of apparently healthy middle-aged men and women, more frequently by peripheral 2D/3DVUS than by CACS. Disease progression, as defined in this study, correlated with almost all cardiovascular risk factors and estimated risk. (Progression of Early Subclinical Atherosclerosis [PESA]; NCT01410318).

Interindividual Variations in the Adenosine-Induced Hemodynamics During Fractional Flow Reserve Evaluation: Implications for the Use of Quantitative Flow Ratio in Assessing Intermediate Coronary Stenoses.

Background Quantitative flow ratio (QFR), a novel functional angiography technique, computes fractional flow reserve (FFR) without pressure wires or adenosine. We investigated interindividual variations in the adenosine-induced hemodynamics during FFR assessment and their influence on QFR diagnostic performance. Methods and Results Patients with coronary stenoses who underwent intracoronary pressure and flow assessment were analyzed. Adenosine-induced hemodynamics during FFR measurement were determined by the percentage change in mean aortic pressure (%ΔPa) and the resistive reserve ratio (RRR). The diagnostic performance of QFR was evaluated and compared in each tertile of %ΔPa and RRR using FFR as reference. A total of 294 vessels (245 patients) were analyzed. Mean FFR was 0.80±0.11. Individuals showed a wide variation in the adenosine response in terms of %ΔPa (ranging from -75% to 43%; median, -9% [interquartile range, -3% to -17%]) and the RRR (ranging from 0.45 to 20.15; median, 3.1 [interquartile range, 2.1-4.9]). No significant differences for diagnostic efficiency of QFR were found between tertiles of %ΔPa (area under the curve for the receiver-operating characteristic analysis, 0.950 in tertile 1, 0.929 in tertile 2, and 0.910 in tertile 3; P=0.270) or between tertiles of the RRR (area under the curve for the receiver-operating characteristic analysis, 0.909 in tertile 1, 0.923 in tertile 2, and 0.959 in tertile 3; P=0.167). The classification agreement between QFR and FFR was not significantly modified by %ΔPa (tertile 1, 89%; tertile 2, 87%; and tertile 3, 86%; P=0.827) or by the RRR (tertile 1, 86%; tertile 2, 85%; and tertile 3, 91%; P=0.398). Conclusions Patients undergoing FFR assessment show large interindividual variations in the magnitude of adenosine-induced hemodynamics. However, such variations do not affect the diagnostic performance of QFR in assessing the functional relevance of observed stenoses.

Screening of extra-coronary arteriopathy with magnetic resonance angiography in patients with spontaneous coronary artery dissection: a single-centre experience.

BACKGROUND: Current consensus recommends extended vascular investigation in patients with spontaneous coronary artery dissection (SCAD). We here report our experience with the use of magnetic resonance angiography (MRA) for screening extra-coronary arteriopathy in patients presenting with SCAD. METHODS: Patients presenting with SCAD in a Spanish centre underwent prospective contrast-enhanced MRA to assess the cephalic and abdominopelvic arterial territories. Fibromuscular dysplasia (FMD) was diagnosed following European consensus criteria. Other vascular abnormalities were recorded separately. Two vascular radiologists supervised the acquisitions and independently analysed the results for all cases. RESULTS: Forty patients with SCAD [mean age 50.9±8.6 years, 90% (n=36) women] were included in the study, 12 patients declined to participate and 5 were excluded (metallic implanted devices). All enrolled patients underwent the screening protocol without complications. MRA demonstrated at least one extra-coronary vascular abnormality in 16 patients (40%): 5 (12.5%) were diagnosed with FMD, 6 (15%) showed arterial tortuosity, 3 (7.5%) had non-FMD focal stenoses, and 2 (5%) were found to have small aneurysms at the celiac trunk and splenic artery. No intracranial aneurysms were detected. At a mean follow-up of 4±3 years from the index episode, two cases experienced SCAD recurrences, one in a patient with FMD and the other one in a patient with arterial tortuosity. No deaths or strokes occurred. CONCLUSIONS: Systematic extended vascular study with MRA was feasible and demonstrated associated extra-coronary arteriopathy in a substantial proportion of patients presenting with SCAD; however, none required additional intervention or led to vascular events. MRA, being a radiation-free modality, may be the preferred method for screening extracoronary arteriopathy in SCAD, a condition primarily affecting young and middle-age women sensitive to the risks of radiation.

Does Socioeconomic Status Influence the Risk of Subclinical Atherosclerosis?: A Mediation Model.

BACKGROUND: Socioeconomic status (SES)-education, income level, and occupation-is associated with cardiovascular risk. OBJECTIVES: This study aimed to investigate the association between SES and subclinical atherosclerosis and the potential mechanisms involved. METHODS: SES, lifestyle habits (smoking, dietary patterns, physical activity, and hours of sleep), traditional risk factors, and subclinical atherosclerosis extent were prospectively assessed in 4,025 individuals aged 40 to 54 years without known cardiovascular disease enrolled in the PESA (Progression of Early Subclinical Atherosclerosis) study. After factors associated with atherosclerosis were identified, a multiple mediation model was created to quantify the effect of SES on subclinical atherosclerosis as explained by lifestyle behaviors. RESULTS: Although education level was significantly associated with the presence of atherosclerosis, no differences were found according to income level in this population. Participants with lower education presented with a higher risk of generalized atherosclerosis than those with higher education (odds ratio: 1.46; 95% confidence interval: 1.15 to 1.85; p = 0.002). Lifestyle behaviors associated with both education level and atherosclerosis extent were: smoking status, number of cigarettes/day, and dietary pattern, which explained 70.5% of the effect of SES on atherosclerosis. Of these, tobacco habit (smoking status 35% and number of cigarettes/day 32%) accounted for most of the explained differences between groups, whereas dietary pattern did not remain a significant mediator in the multiple mediation model. CONCLUSIONS: Despite the relative economic homogeneity of the cohort, lower education level is associated with increased subclinical atherosclerosis, mainly mediated by the higher and more frequent tobacco consumption. Smoking cessation programs are still needed, particularly in populations with lower education level.

Coronary Microcirculation Downstream Non-Infarct-Related Arteries in the Subacute Phase of Myocardial Infarction: Implications for Physiology-Guided Revascularization.

Background Concerns exist about reliability of pressure-wire-guided coronary revascularization of non-infarct-related arteries (non- IRA ). We investigated whether physiological assessment of non- IRA during the subacute phase of myocardial infarction might be flawed by microcirculatory dysfunction. Methods and Results We analyzed non- IRA that underwent fractional flow reserve, coronary flow reserve, and the index of microcirculatory resistance assessment. Microcirculation and hyperemic response were evaluated in 49 acute myocardial infarction patients (59 non- IRA ) and compared with a matched control group of 46 stable angina ( SA ) patients (59 vessels). Time between acute myocardial infarction to physiological interrogation was 5.9±2.4 days. Fractional flow reserve was similar in both groups (0.79±0.11 in non- IRA versus 0.80±0.13 in SA vessels, P=0.527). Lower coronary flow reserve values were found in non- IRA compared with SA vessels (1.77 [1.25-2.76] versus 2.44 [1.63-4.00], P=0.018), primarily driven by an increased baseline flow in non- IRA (rest mean transit time 0.58 [0.32-0.83] versus 0.65 s [0.39-1.20], P=0.045), whereas the hyperemic flow was similar (hyperemic mean transit time 0.26 [0.20-0.42] versus 0.26 s [0.18-0.35], P=0.873). No differences were found regarding index of microcirculatory resistance (15.6 [10.4-21.8] in non- IRA versus 16.7 [11.6-23.6] U in SA vessels, P=0.559). During adenosine infusion, the hyperemic response was similar in both groups (non- IRA versus SA vessels) in terms of the resistive reserve ratio (3.1±2.1 versus 3.7±2.2, P=0.118). Conclusions In the subacute phase of myocardial infarction, non- IRA show an increased baseline flow that may cause abnormal coronary flow reserve despite preserved hyperemic flow. In non- IRA , microcirculatory resistance and adenosine-induced hyperemic response are similar to those found in SA patients. From a physiological perspective, these findings support the use of fractional flow reserve to interrogate non- IRA during the subacute phase of myocardial infarction.
