Epidemiology and Prognostic Implications of Coronary Artery Calcium in Asymptomatic Individuals With Prediabetes: A Multicohort Study.

OBJECTIVE: To describe the epidemiology and prognostic value of coronary artery calcium (CAC) in individuals with prediabetes. RESEARCH DESIGN AND METHODS: We pooled participants free of clinical atherosclerotic cardiovascular disease (ASCVD) from four prospective cohorts: the Multi-Ethnic Study of Atherosclerosis, Heinz Nixdorf Recall Study, Framingham Heart Study, and Jackson Heart Study. Two definitions were used for prediabetes: inclusive (fasting plasma glucose [FPG] ≥100 to <126 mg/dL and hemoglobin A1c [HbA1c] ≥5.7% to <6.5%, if available, and no glucose-lowering medications) and restrictive (FPG ≥110 to <126 mg/dL and HbA1c ≥5.7% to <6.5%, if available, among participants not taking glucose-lowering medications). RESULTS: The study included 13,376 participants (mean age 58 years; 54% women; 57% White; 27% Black). The proportions with CAC ≥100 were 17%, 22%, and 37% in those with euglycemia, prediabetes, and diabetes, respectively. Over a median (25th-75th percentile) follow-up time of 14.6 (interquartile range 7.8-16.4) years, individuals with prediabetes and CAC ≥100 had a higher unadjusted 10-year incidence of ASCVD (13.4%) than the overall group of those with diabetes (10.6%). In adjusted analyses, using the inclusive definition of prediabetes, compared with euglycemia, the hazard ratios (HRs) for ASCVD were 0.79 (95% CI 0.62, 1.01) for prediabetes and CAC 0, 0.70 (0.54, 0.89) for prediabetes and CAC 1-99, 1.54 (1.27, 1.88) for prediabetes and CAC ≥100, and 1.64 (1.39, 1.93) for diabetes. Using the restrictive definition, the HR for ASCVD was 1.63 (1.29, 2.06) for prediabetes and CAC ≥100. CONCLUSIONS: CAC ≥100 is frequent among individuals with prediabetes and identifies a high ASCVD risk subgroup in which the adjusted ASCVD risk is similar to that in individuals with diabetes.

Placement of a self-expanding transcatheter aortic valve prosthesis in the presence of aortic arch angulation.

An 83-year-old man with symptomatic severe aortic valve stenosis with severe ventricular dysfunction underwent valvuloplasty with a 25-mm NuCLEUS-X balloon (B. Braun Interventional Systems) and percutaneous coronary intervention of the left main and circumflex arteries (left anterior descending artery presented a chronic total occlusion without viability of this territory) before being referred for transcatheter aortic valve replacement.

Efectividad y seguridad de una estrategia de antiagregación plaquetaria simple tras cierre percutáneo de orejuela izquierda en pacientes con FA / Single antiplatelet therapy after left atrial appendage closure in patients with AF: safety and effectiveness

Introduction and objectives The optimal antithrombotic strategy following left atrial appendage closure (LAAC) is poorly defined in patients with nonvalvular atrial fibrillation. We assessed the safety and effectiveness of a single antiplatelet treatment (SAPT) strategy after LAAC in a population at high risk of ischemic and bleeding events. Methods This single-center, observational, prospective study included a consecutive cohort of patients who underwent LAAC using the LAmbre device (Lifetech Scientific, China) and who were discharged with SAPT. The primary outcome was a composite of stroke, systemic embolism, and device-related thrombosis during follow-up. Secondary endpoints were cardiovascular mortality and major bleeding events (BARC ≥3a). Clinical follow-up was performed at 1, 6, and 12 months and subsequently on an annual basis. Transesophageal echocardiography was performed at 1 and 12 months of follow-up. Results The study comprised 74 patients. The median age was 77 [72-83] years and 43% were women. The cohort exhibited a high prevalence of comorbidities and cardiovascular risk factors. The median CHA2DS2-VASc and HAS-BLED scores were 4 [3-6] and 4 [4-5], respectively. The median length of follow-up was 2.5 years (188 patients-year). During follow-up, device-related thrombosis occurred in 3 patients (4%). Ischemic stroke occurred in 1 patient (1.3%, rate 0.5%/y), representing a 90.9% relative risk reduction compared with the risk predicted by CHA2DS2-VASc. Major bleeding events occurred in 12 patients (16%, 6.4%/y), with a relative risk reduction of 26.4% of that predicted by HAS-BLED. Cardiovascular-related mortality was observed in 2 patients (2.7%). Conclusions SAPT appears to be a safe and effective treatment following LAAC in patients at high ischemic and hemorrhagic risk. Further studies are needed to confirm our findings (AU)

Introducción y objetivos Se desconoce cuál es la terapia antitrombótica óptima tras el cierre percutáneo de la orejuela izquierda (CPOI) en pacientes con fibrilación auricular no valvular. El objetivo de este estudio es analizar la efectividad y la seguridad de un régimen de tratamiento antiagregante plaquetario simple (TAPS) tras el CPOI en una población con alto riesgo isquémico y hemorrágico. Métodos Estudio observacional prospectivo que incluyó una cohorte consecutiva de pacientes a los que se realizó CPOI con dispositivo LAmbre (Lifetech Scientific, China) y que recibieron TAPS al alta. El evento primario fue un combinado de ictus, embolia sistémica y trombosis del dispositivo. Los eventos secundarios fueron mortalidad cardiovascular y hemorragia mayor (BARC ≥ 3a). Se realizó seguimiento clínico al mes y a los 6 y 12 meses y cada año después. Se realizó ecocardiograma transesofágico al mes y a los 12 meses. Resultados Se incluyó a 74 pacientes (el 43% mujeres) con una mediana de edad de 77 [intervalo intercuartílico, 72-83] años, que presentaban gran comorbilidad y factores de riesgo cardiovascular. Los valores de CHA2DS2-VASc y HAS-BLED fueron una mediana de 4 [3-6] y 4 [4-5] respectivamente. Durante el seguimiento (mediana, 2,5 años), 3 pacientes (4%) presentaron trombosis del dispositivo. Uno sufrió ictus isquémico (1,3%, 0,5%/año), lo que supone, según la incidencia esperada por CHA2DS2-VASc, una reducción del riesgo relativo del 90,9%. Sufrieron eventos hemorrágicos 12 pacientes (16%; 6,4%/año), una tasa el 26,4% menor que el riesgo HAS-BLED predicho. Se produjo la muerte cardiovascular de 2 pacientes (2,7%). Conclusiones Una estrategia de TAPS tras el CPOI parece ser una opción efectiva y segura para los pacientes con altos riesgos isquémico y hemorrágico. Se necesitan más estudios que corroboren nuestros resultados (AU)

Genetic characteristics involved in COVID-19 severity. The CARGENCORS case-control study and meta-analysis.

Pre-existing coronary artery disease (CAD), and thrombotic, inflammatory, or virus infectivity response phenomena have been associated with COVID-19 disease severity. However, the association of candidate single nucleotide variants (SNVs) related to mechanisms of COVID-19 complications has been seldom analysed. Our aim was to test and validate the effect of candidate SNVs on COVID-19 severity. CARGENCORS (CARdiovascular GENetic risk score for Risk Stratification of patients positive for SARS-CoV-2 [COVID-19] virus) is an age- and sex-matched case-control study with 818 COVID-19 cases hospitalized with hypoxemia, and 1636 controls with COVID-19 treated at home. The association between severity and SNVs related to CAD (n = 32), inflammation (n = 19), thrombosis (n = 14), virus infectivity (n = 11), and two published to be related to COVID-19 severity was tested with adjusted logistic regression models. Two external independent cohorts were used for meta-analysis (SCOURGE and UK Biobank). After adjustment for potential confounders, 14 new SNVs were associated with COVID-19 severity in the CARGENCORS Study. These SNVs were related to CAD (n = 10), thrombosis (n = 2), and inflammation (n = 2). We also confirmed eight SNVs previously related to severe COVID-19 and virus infectivity. The meta-analysis showed five SNVs associated with severe COVID-19 in adjusted analyses (rs11385942, rs1561198, rs6632704, rs6629110, and rs12329760). We identified 14 novel SNVs and confirmed eight previously related to COVID-19 severity in the CARGENCORS data. In the meta-analysis, five SNVs were significantly associated to COVID-19 severity, one of them previously related to CAD.

CONCLUSIONS: SAPT appears to be a safe and effective treatment following LAAC in patients at high ischemic and hemorrhagic risk. Further studies are needed to confirm our findings.

Non-atherosclerotic acute cardiac syndromes: spontaneous coronary artery dissection and Takotsubo syndrome. Comparison of long-term clinical outcomes.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) and Takotsubo syndrome (TTS) constitute two common causes of nonatherosclerotic acute cardiac syndrome particularly frequent in women. Currently, there is no information comparing long-term clinical outcomes in unselected patients with these conditions. METHODS: We compared the baseline characteristics, in-hospital outcomes, and the 12-month and long-term clinical outcomes of two large prospective registries on SCAD and TTS. RESULTS: A total of 289 SCAD and 150 TTS patients were included; 89% were women. TTS patients were older with a higher prevalence of cardiovascular risk factors. Precipitating triggers were more frequent in TTS patients, while emotional triggers and depressive disorders were more common in the SCAD group. Left ventricular ejection fraction was lower in TTS patients, but SCAD patients showed higher cardiac biomarkers. In-hospital events (43.3% vs. 5.2%, P <0.01) occurred more frequently in TTS patients. TTS patients also presented more frequent major adverse events at 12-month (14.7% vs. 7.1%, HR 5.3, 95% CI: 2.4-11.7, P <0.01) and long-term (median 36 vs. 31 months, P =0.41) follow-up (25.8% vs. 9.6%, HR 4.5, 95% CI: 2.5-8.2, P <0.01). Atrial fibrillation was also more frequent in TTS patients. Moreover, TTS patients presented a higher 12-month and long-term mortality (5.6% vs. 0.7%, P =0.01; and 12.6% vs. 0.7%, P <0.01) mainly driven by noncardiovascular deaths. CONCLUSION: Compared to SCAD, TTS patients are older and present more cardiovascular risk factors but less frequent depressive disorder or emotional triggers. TTS patients have a worse in-hospital, mid-term, and long-term prognosis with higher noncardiac mortality than SCAD patients.

Analysis of myocardial infarction incidence and case-fatality in the last three decades in the province of Girona.

INTRODUCTION AND OBJECTIVES: Myocardial infarction (MI) incidence and case fatality trends are highly informative but relatively untested at the population level. The objective of this work was to estimate MI incidence and case fatality in the Girona population aged 35-74 years, and to determine their 30-year trends (1990-2019). METHODS: The REGICOR (Girona Heart Registry) monitored MI incidence and case fatality rates from 1990 to 2008. For the period 2008 to 2019, we linked discharges from Girona hospitals (n=4 974 977) and mortality registry (n=70 405) during this period. Our linkage algorithm selected key MI diagnostic codes and removed duplicates. Estimates from the linkage algorithm and the REGICOR registry were compared using chi-square tests for overlapping years (2008-2009). We estimated the annual percent change (APC) of standardized MI incidence and 28-day case fatality, and analyzed their trends using joinpoint regression. RESULTS: MI incidence and case fatality estimates were similar in the linkage algorithm and the REGICOR registry. We observed significant decreasing trends in the incidence of MI. The trend was APC, -0.96% (95% confidence interval (95%CI), -1.4 to -0.53) in women from 1990 to 2019 and -4.2% (95%CI, -5.5 to -3.0) in men from 1994 to 2019. The largest decrease in case fatality was -3.8% (95%CI, -5.1 to -2.5) from 1995 to 2003 in women and -2.4% (95%CI, -2.9 to -1.9) from 1995 to 2004 in men, mainly due to prehospital case fatality declines: -1.8% (95%CI, -2.6 to -1.1) in men and -3.2% (95%CI, -4.6 to -1.8) in women. CONCLUSIONS: In Girona, MI incidence and case fatality decreased between 1990 and 2019. The incidence showed a slow but continuous decrease while case fatality only stabilized in the last decade, particularly in women.

Perfil clínico y pronóstico de pacientes jóvenes con infarto agudo de miocardio con elevación del segmento ST tratados en la red Codi IAM / Clinical profile and prognosis of young patients with ST-elevation myocardial infarction managed by the emergency-intervention Codi IAM network

Introducción y objetivos: Los datos sobre el perfil clínico y los resultados de los pacientes jóvenes con infarto agudo de miocardio con elevación del segmento ST (SCACEST) son escasos. Este estudio compara las características y los resultados clínicos entre pacientes de edades<45 años y ≥ 45 con IAMCEST atendidos por el sistema catalán Codi IAM. También se analizaron las diferencias por sexo en el grupo de menores de 45 años.Métodos: Entre 2015 y 2020, se incluyó a todos los pacientes ingresados por IAMCEST. Los objetivos primarios fueron la mortalidad por cualquier causa en los primeros 30 días, a 1 año y 2 años.Resultados: Se incluyó a 18.933 pacientes (el 23% mujeres). De ellos, 1.403 (7,4%) eran menores de 45 años. Los pacientes más jóvenes eran más fumadores (p<0,001) y presentaron tasas más altas de muerte súbita y flujo TIMI 0 antes de la ICPp (p<0,05), pero el tiempo desde el primer contacto médico hasta el paso de la guía fue más corto en comparación con el grupo de más edad (p<0,05). Se observaron tasas de mortalidad por cualquier causa más bajas en los pacientes menores de 45 (p<0,001). Con respecto a las diferencias estratificadas por sexo en los pacientes más jóvenes, el shock cardiogénico fue más frecuente en las mujeres que en los varones (p=0,002) y el tiempo desde el inicio de los síntomas hasta la reperfusión fue más largo (p<0,05) en el grupo de las mujeres. En comparación con los varones de menos de 45, las mujeres más jóvenes tenían menos probabilidades de tratarse con ICPp (p=0,004).Conclusiones: Pese a presentar características de alto riesgo al ingreso, los pacientes jóvenes que sufren un IAMCEST tienen mejor pronóstico que sus contrapartes mayores. Se observaron diferencias en los tiempos de isquemia y tratamiento entre varones y mujeres.(AU)

Introduction and objectives: Data on the clinical profile and outcomes of younger patients with ST-elevation myocardial infarction (STEMI) is scarce. This study compared clinical characteristics and outcomes between patients aged<45 years and those aged ≥ 45 years with STEMI managed by the acute myocardial infarction code (AMI Code) network. Sex-based differences in the younger cohort were also analyzed.Methods: This multicenter study collected individual data from the Catalonian AMI Code network. Between 2015 and 2020, we enrolled patients with an admission diagnosis of STEMI. Primary endpoints were all-cause mortality within 30 days, 1 year, and 2 years.Results: Overall, 18 933 patients (23% female) were enrolled. Of them, 1403 participants (7.4%) were aged<45 years. Younger patients with STEMI were more frequently smokers (P<.001) and presented with cardiac arrest and TIMI flow 0 before pPCI (P<.05), but the time from first medical contact to wire crossing was shorter than in the older group (P<.05). All-cause mortality rates were lower in patients aged<45 years (P<.001). Among younger patients, cardiogenic shock was most prevalent in women than in their male counterparts (P=.002), with the time from symptom onset to reperfusion being longer (P<.05). Compared with men aged<45 years, younger women were less likely to undergo pPCI (P=.004).Conclusions: Despite showing high-risk features on admission, young patients exhibit better outcomes than older patients. Differences in ischemia times and treatment were observed between men and women.(AU)

Long-term survival after cardiac arrest in patients undergoing emergent coronary angiography.

AIM: To determine long-term survival of patients after cardiac arrest undergoing emergent coronary angiography and therapeutic hypothermia. METHODS: We analysed data from patients treated within the regional STEMI Network from January 2015 to December 2020. The primary endpoint was all-cause mortality at median follow-up. Secondary endpoints were periprocedural complications (arrhythmias, pulmonary edema, cardiogenic shock, mechanical complication, stent thrombosis, reinfarction, bleeding) and 6-month all-cause death. A landmark analysis was performed, studying two time periods; 0-6 months and beyond 6 months. RESULTS: From a total of 24,125 patients in the regional STEMI network, 494 patients who suffered from cardiac arrest were included and divided into two groups: treated with (n = 119) and without therapeutic hypothermia (n = 375). At median follow-up (16.0 [0.2-33.3] months), there was no difference in the adjusted mortality rate between groups (51.3 % with hypothermia vs 48.0 % without hypothermia; HRadj1.08 95%CI [0.77-1.53]; p = 0.659). There was a higher frequency of bleeding in the hypothermia group (6.7 % vs 1.1 %; ORadj 7.99 95%CI [2.05-31.2]; p = 0.002), without difference for the rest of periprocedural complications. At 6-month follow-up, adjusted all-cause mortality rate was similar between groups (46.2 % with hypothermia vs 44.5 % without hypothermia; HRadj1.02 95%CI [0.71-1.47]; p = 0.900). Also, no differences were observed in the adjusted mortality rate between 6 months and median follow-up (9.4 % with hypothermia vs 6.3 % without hypothermia; HRadj2.02 95%CI [0.69-5.92]; p = 0.200). CONCLUSIONS: In a large cohort of patients with cardiac arrest within a regional STEMI network, those treated with therapeutic hypothermia did not improve long-term survival compared to those without hypothermia.

Pronóstico a largo plazo de la extensión de la TAPD en una cohorte consecutiva de pacientes con IAMCEST / Long-term outcomes of extended DAPT in a real-life cohort of consecutive STEMI patients

Introducción y objetivos: La duración adecuada de la doble terapia antiagregante (DAPT) después de un infarto de miocardio con elevación del segmento ST (IAMCEST) está todavía en discusión. Métodos: Analizamos el efecto de la DAPT extendida a 5 años sobre la mortalidad global, mortalidad cardiovascular y reingreso o mortalidad cardiovascular, en una cohorte multicéntrica de pacientes con IAMCEST supervivientes al año. Resultados: Se incluyeron 3.107 pacientes hospitalizados por IAMCEST de los que el 93% recibió DAPT al alta. A los 5 años se mantenía en 275 pacientes con un perfil alto de gravedad. La mortalidad cardiovascular de los pacientes con antiagregación simple (SAPT) frente a DAPT a 5 años fue de 1,4 y 3,6% (p <0,01), respectivamente. La mortalidad no-cardiovascular fue del 3,3 frente a 5,8% (p=0,049) a 5 años, respectivamente. La incidencia del evento combinado a un año fue del 14,6% en SAPT frente a 11,8% en DAPT (p=0,496), y del 11,4 frente a 46,5% (p <0,001) a 5 años, respectivamente. El mantenimiento de la DAPT hasta los 5 años se asoció de forma independiente a mayor mortalidad: por cualquier causa (HR=2,16; IC95%, 1,40-3,33), cardiovascular (HR=2,83; IC95%, 1,37-5,84) y rehospitalización cardiovascular y mortalidad (HR=5,20; IC95%, 3,96-6,82). Un análisis emparejado por puntuación de propensión, y uno con ponderación de probabilidad inversa, confirman estos resultados. Conclusiones: Nuestros resultados sugieren la hipótesis de que, en supervivientes a un año de IAMCEST, alargar la DAPT hasta 5 años en pacientes de alto riesgo no mejora su pronóstico a largo plazo.

Introduction and objectives: Dual antiplatelet therapy (DAPT) duration after ST-segment elevation myocardial infarction (STEMI) remains a matter of debate. Methods: We analyzed the effect of DAPT on 5-year all-cause mortality, cardiovascular mortality, and cardiovascular readmission or mortality in a cohort of 1-year survivor STEMI patients. Results: A total of 3107 patients with the diagnosis of STEMI were included: 93% of them were discharged on DAPT, a therapy that persisted in 275 high-risk patients at 5 years. Cardiovascular mortality in patients on single antiplatelet therapy vs DAPT at 5 years was 1.4% vs 3.6% (P <.01), respectively, whereas noncardiovascular mortality was 3.3% vs 5.8% (P=.049) at 5 years. Cardiovascular readmission or mortality in patients with single antiplatelet therapy vs DAPT was 11.4% vs 46.5% (P <.001). Extended DAPT was independently associated with worse 5-year all-cause mortality (HR, 2.16; 95%CI, 1.40-3.33), cardiovascular mortality (HR, 2.83; 95%CI, 1.37-5.84), and cardiovascular readmission or mortality (HR, 5.20; 95%CI, 3.96-6.82). These findings were confirmed in propensity score matching and inverse probability weighting analyses. Conclusions: Our results suggest the hypothesis that, in 1-year STEMI survivors, extending DAPT up to 5 years in high-risk patients does not improve their long-term prognosis. (AU)

Subclinical congestion assessed by lung ultrasound in ST segment elevation myocardial infarction.

OBJECTIVE: We evaluated the prognostic value of subclinical congestion assessed by lung ultrasound (LUS) in patients admitted for ST segment elevation myocardial infarction (STEMI). METHODS: This was a multicentre study that prospectively enrolled 312 patients admitted for STEMI without signs of heart failure (HF) at admission. LUS was performed during the first 24 hours after revascularisation and classified patients as having either wet lung (three or more B-lines in at least one lung field) or dry lung. The primary endpoint was a composite of acute HF, cardiogenic shock or death during hospitalisation. The secondary endpoint was a composite of readmission for HF or new acute coronary syndrome or death during 30-day follow-up. Zwolle score was calculated in all patients to assess predictive improvement by adding the result of the LUS to this score. RESULTS: 14 patients (31.1%) in the wet lung group presented the primary endpoint vs 7 (2.6%) in the dry lung group (adjusted RR 6.0, 95% CI 2.3 to 16.2, p=0.007). The secondary endpoint occurred in five patients (11.6%) in the wet lung group and in three (1.2%) in the dry lung group (adjusted HR 5.4, 95% CI 1.0 to 28.7, p=0.049). Addition of LUS improved the ability of the Zwolle score to predict the follow-up composite endpoint (net reclassification improvement 0.99). LUS showed a very high negative predictive value in predicting in-hospital and follow-up endpoints (97.4% and 98.9%, respectively). CONCLUSION: Early subclinical pulmonary congestion identified by LUS in patients with Killip I STEMI at hospital admission is associated with adverse outcomes during hospitalisation and 30-day follow-up.

Five-Year Changes in Inflammatory, Metabolic, and Oxidative Biomarkers and 10-Year Cardiovascular Disease Incidence: The REGICOR Cohort Study.

Ischemic cardiovascular diseases (CVD) originate from an imbalance between atherosclerotic plaque formation, instability, and endothelial healing dynamics. Our aim was to examine the relationship between 5-year changes in inflammatory, metabolic, and oxidative biomarkers and 10-year CVD incidence in a population without previous CVD. This was a prospective cohort study of individuals aged 35-74 years (n = 419) randomly selected from 5263 REGICOR participants without CVD recruited in 2005. Biomarkers were measured at baseline and in 2010. Participants were followed up until 2020 for a composite CVD endpoint including coronary artery disease, stroke, and peripheral artery disease. We used Cox regression to analyze the effect of biomarker levels on the occurrence of the composite endpoint, adjusted for traditional CVD risk factors and baseline levels of each biomarker. Individuals with elevated IL-6 or insulin after 5 years had a higher independent risk of CVD at 10 years, compared to those with lower levels. Each rise of 1 pg/mL of IL-6 or 10 pg/mL of insulin increased the 10-year risk of a CVD event by 32% and 2%, respectively. Compared to a model with traditional CVD risk factors only, the inclusion of IL-6 and insulin improved continuous reclassification by 51%. Elevated serum levels of IL-6 and insulin were associated with a higher risk of CVD at 10 years, independently of traditional CVD risk factors.

Clinical profile and prognosis of young patients with ST-elevation myocardial infarction managed by the emergency-intervention Codi IAM network.

INTRODUCTION AND OBJECTIVES: Data on the clinical profile and outcomes of younger patients with ST-elevation myocardial infarction (STEMI) is scarce. This study compared clinical characteristics and outcomes between patients aged<45 years and those aged ≥ 45 years with STEMI managed by the acute myocardial infarction code (AMI Code) network. Sex-based differences in the younger cohort were also analyzed. METHODS: This multicenter study collected individual data from the Catalonian AMI Code network. Between 2015 and 2020, we enrolled patients with an admission diagnosis of STEMI. Primary endpoints were all-cause mortality within 30 days, 1 year, and 2 years. RESULTS: Overall, 18 933 patients (23% female) were enrolled. Of them, 1403 participants (7.4%) were aged<45 years. Younger patients with STEMI were more frequently smokers (P<.001) and presented with cardiac arrest and TIMI flow 0 before pPCI (P<.05), but the time from first medical contact to wire crossing was shorter than in the older group (P<.05). All-cause mortality rates were lower in patients aged<45 years (P<.001). Among younger patients, cardiogenic shock was most prevalent in women than in their male counterparts (P=.002), with the time from symptom onset to reperfusion being longer (P<.05). Compared with men aged<45 years, younger women were less likely to undergo pPCI (P=.004). CONCLUSIONS: Despite showing high-risk features on admission, young patients exhibit better outcomes than older patients. Differences in ischemia times and treatment were observed between men and women.

Performance analysis of a STEMI network: prognostic impact of the type of first medical contact facility.

INTRODUCTION AND OBJECTIVES: Prognosis in ST-elevation myocardial infarction (STEMI) is determined by delay in primary percutaneous coronary intervention (PPCI). The impact of first medical contact (FMC) facility type on reperfusion delays and mortality remains controversial. METHODS: We performed a prospective registry of primary coronary intervention (PCI)-treated STEMI patients (2010-2020) in the Codi Infart STEMI network. We analyzed 1-year all-cause mortality depending on the FMC facility type: emergency medical service (EMS), community hospital (CH), PCI hospital (PCI-H), or primary care center (PCC). RESULTS: We included 18 332 patients (EMS 34.3%; CH 33.5%; PCI-H 12.3%; PCC 20.0%). Patients with Killip-Kimball classes III-IV were: EMS 8.43%, CH 5.54%, PCI-H 7.51%, PCC 3.76% (P <.001). All comorbidities and first medical assistance complications were more frequent in the EMS and PCI-H groups (P <.05) and were less frequent in the PCC group (P <.05 for most variables). The PCI-H group had the shortest FMC-to-PCI delay (median 82 minutes); the EMS group achieved the shortest total ischemic time (median 151 minutes); CH had the longest reperfusion delays (P <.001). In an adjusted logistic regression model, the PCI-H and CH groups were associated with higher 1-year mortality, OR, 1.22 (95%CI, 1.00-1.48; P=.048), and OR, 1.17 (95%CI 1.02-1.36; P=.030), respectively, while the PCC group was associated with lower 1-year mortality than the EMS group, OR, 0.71 (95%CI 0.58-0.86; P <.001). CONCLUSIONS: FMC with PCI-H and CH was associated with higher adjusted 1-year mortality than FMC with EMS. The PCC group had a much lower intrinsic risk and was associated with better outcomes despite longer revascularization delays.

Multivessel spontaneous coronary artery dissection: Clinical features, angiographic findings, management, and outcomes.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Multivessel (MV) SCAD is a challenging clinical presentation that might be associated to a worse prognosis compared with patients with single-vessel (SV) involvement. METHODS: The Spanish multicentre nationwide prospective SCAD registry included 389 consecutive patients. Patients were classified, according to the number of affected vessels, in SV or MV SCAD. Major adverse events (MAE) were analyzed during hospital stay and major cardiac or cerebrovascular adverse events (MACCE) at long-term clinical follow-up. RESULTS: A total of 41 patients (10.5%) presented MV SCAD. These patients had more frequently a previous history of hypothyroidism (22% vs 11%, p = 0.04) and anxiety disorder (32% vs 16%, p = 0.01). MV SCAD patients presented more often as non-ST segment elevation myocardial infarction (73% vs 52%, p = 0.01) and showed less frequently type 1 angiographic lesions (12% vs 21%, p = 0.04). An impaired initial Thrombolysis In Myocardial Infarction (TIMI) flow 0-1 was less frequent (14% vs 29%, p < 0.01) in MV SCAD. In both groups, most patients were treated conservatively (71% vs 79%, p = NS). No differences were found regarding in-hospital MAE or MACCE at late follow-up (median 29 ± 11 months). However, the rate of stroke was higher in MV SCAD patients, both in-hospital (2.4% vs 0%, p < 0.01) and at follow-up (5.1% vs 0.6%, p = 0.01). CONCLUSIONS: Patients with MV SCAD have some distinctive clinical and angiographic features. Although composite clinical outcomes, in-hospital and at long-term follow-up, were similar to those seen in patients with SV SCAD, stroke rate was significantly higher in patients with MV SCAD.

Long-term outcomes of extended DAPT in a real-life cohort of consecutive STEMI patients.

INTRODUCTION AND OBJECTIVES: Dual antiplatelet therapy (DAPT) duration after ST-segment elevation myocardial infarction (STEMI) remains a matter of debate. METHODS: We analyzed the effect of DAPT on 5-year all-cause mortality, cardiovascular mortality, and cardiovascular readmission or mortality in a cohort of 1-year survivor STEMI patients. RESULTS: A total of 3107 patients with the diagnosis of STEMI were included: 93% of them were discharged on DAPT, a therapy that persisted in 275 high-risk patients at 5 years. Cardiovascular mortality in patients on single antiplatelet therapy vs DAPT at 5 years was 1.4% vs 3.6% (P <.01), respectively, whereas noncardiovascular mortality was 3.3% vs 5.8% (P=.049) at 5 years. Cardiovascular readmission or mortality in patients with single antiplatelet therapy vs DAPT was 11.4% vs 46.5% (P <.001). Extended DAPT was independently associated with worse 5-year all-cause mortality (HR, 2.16; 95%CI, 1.40-3.33), cardiovascular mortality (HR, 2.83; 95%CI, 1.37-5.84), and cardiovascular readmission or mortality (HR, 5.20; 95%CI, 3.96-6.82). These findings were confirmed in propensity score matching and inverse probability weighting analyses. CONCLUSIONS: Our results suggest the hypothesis that, in 1-year STEMI survivors, extending DAPT up to 5 years in high-risk patients does not improve their long-term prognosis.

Cholesterol and Hypertension Treatment Improve Coronary Risk Prediction but Not Time-Dependent Covariates or Competing Risks.

Background and Aims: Cardiovascular (CV) risk functions are the recommended tool to identify high-risk individuals. However, their discrimination ability is not optimal. While the effect of biomarkers in CV risk prediction has been extensively studied, there are no data on CV risk functions including time-dependent covariates together with other variables. Our aim was to examine the effect of including time-dependent covariates, competing risks, and treatments in coronary risk prediction. Methods: Participants from the REGICOR population cohorts (North-Eastern Spain) aged 35-74 years without previous history of cardiovascular disease were included (n = 8470). Coronary and stroke events and mortality due to other CV causes or to cancer were recorded during follow-up (median = 12.6 years). A multi-state Markov model was constructed to include competing risks and time-dependent classical risk factors and treatments (2 measurements). This model was compared to Cox models with basal measurement of classical risk factors, treatments, or competing risks. Models were cross-validated and compared for discrimination (area under ROC curve), calibration (Hosmer-Lemeshow test), and reclassification (categorical net reclassification index). Results: Cancer mortality was the highest cumulative-incidence event. Adding cholesterol and hypertension treatment to classical risk factors improved discrimination of coronary events by 2% and reclassification by 7-9%. The inclusion of competing risks and/or 2 measurements of risk factors provided similar coronary event prediction, compared to a single measurement of risk factors. Conclusion: Coronary risk prediction improves when cholesterol and hypertension treatment are included in risk functions. Coronary risk prediction does not improve with 2 measurements of covariates or inclusion of competing risks.

Real-World Multicenter Coronary Lithotripsy Registry: Long-Term Clinical Follow-Up.

OBJECTIVES: Coronary lithotripsy (CL) works by fracturing the calcified plaque, allowing mean area gain, enhancing vessel compliance, and facilitating stent deployment. This study reports the safety, effectiveness, and durability of the clinical benefit of CL at long-term follow-up of a real-world multicenter registry. METHODS: This was a prospective, multicenter, single-arm study that included consecutive patients with calcified lesions undergoing CL from August, 2018 to October, 2020 with a clinical follow-up of 20 months (interquartile range, 14.5-25). Exclusion criteria were a target lesion located in a vessel <2.5 mm and/or the presence of dissection prior to CL. The primary endpoint was the rate of major adverse cardiovascular event (MACE, defined as death or target-lesion revascularization [TLR] or myocardial infarction [MI]) at follow-up. RESULTS: This registry included 109 patients (128 lesions). The population was elderly (mean age, 74 years old), with high rates of diabetic patients (58%), renal insufficiency (32%), and multivessel disease (76%). Most of the lesions were predilated with semicompliant/noncompliant balloons (25 with cutting balloon). Rotational atherectomy was used in 20 lesions. On average, CL required the use of 1 balloon delivering a mean of 60 pulses. Twelve patients presented with ST-segment-elevation MI and a culprit calcified coronary lesion undergoing CL. Successful CL was achieved in 99% of cases. There were few procedural complications, with 30-day freedom from MACE rate of 98%. The MACE rate at long-term follow-up was 5.6%. CONCLUSION: This is the first real-world, multicenter registry that confirms the safety and long-term efficacy of percutaneous coronary intervention for calcified lesions using CL in an unselected and high-risk population with a low long-term follow-up MACE rate.

Socioeconomic Status and Prognosis of Patients With ST-Elevation Myocardial Infarction Managed by the Emergency-Intervention "Codi IAM" Network.

Background: Despite the spread of ST-elevation myocardial infarction (STEMI) emergency intervention networks, inequalities in healthcare access still have a negative impact on cardiovascular prognosis. The Family Income Ratio of Barcelona (FIRB) is a socioeconomic status (SES) indicator that is annually calculated. Our aim was to evaluate whether SES had an effect on mortality and complications in patients managed by the "Codi IAM" network in Barcelona. Methods: This is a cohort study with 3,322 consecutive patients with STEMI treated in Barcelona from 2010 to 2016. Collected data include treatment delays, clinical and risk factor characteristics, and SES. The patients were assigned to three SES groups according to FIRB score. A logistic regression analysis was conducted to estimate the adjusted effect of SES on 30-day mortality, 30-day composite cardiovascular end point, and 1-year mortality. Results: The mean age of the patients was 65 ± 13% years, 25% were women, and 21% had diabetes mellitus. Patients with low SES were younger, more often hypertensive, diabetic, dyslipidemic (p < 0.003), had longer reperfusion delays (p < 0.03) compared to participants with higher SES. Low SES was not independently associated with 30-day mortality (OR: 0.95;9 5% CI: 0.7-1.3), 30-day cardiovascular composite end point (OR: 1.03; 95% CI: 0.84-1.26), or 1-year all-cause mortality (HR: 1.09; 95% CI: 0.76-1.56). Conclusion: Although the low-SES patients with STEMI in Barcelona city were younger, had worse clinical profiles, and had longer revascularization delays, their 30-day and 1-year outcomes were comparable to those of the higher-SES patients.

Impact of COVID-19 on Hospital Admissions and Healthcare Quality Indicators in Non-COVID Patients: A Retrospective Study of the First COVID-19 Year in a University Hospital in Spain.

Few studies have assessed the impact of the COVID-19 pandemic on non-COVID diseases and healthcare quality. We aimed to evaluate changes in rates of hospitalisations, complications, in-hospital mortality, and readmissions among patients with non-COVID diseases during a one-year period after the pandemic onset. From March 2018 to February 2021 a retrospective observational study of hospital admissions in a university hospital in Spain was conducted. Non-COVID hospitalisations admitted through the emergency department were compared between the pre-COVID period (n = 28,622) and the COVID period (n = 11,904). We assessed rate ratios (RaR), comparing the weekly number of admissions and risk ratios (RR) to examine rates of complications, in-hospital mortality, readmissions, and severity. Statistical significance was set at p < 0.05. The weekly admission rate dropped by 20.8% during the complete lockdown. We observed significant reductions in admissions related to diseases of the respiratory system and circulatory system. Admissions for endocrine and metabolic diseases increased. The complication rates increased (RR = 1.21, 95% CI: 1.05;1.4), while in-hospital mortality rates held steady during the COVID period (RR = 1.09, 95% CI: 0.98;1.2). Hospital efforts to maintain quality and safety standards despite disruptions translated into a moderate increase in complications but not in in-hospital mortality. Reduced hospitalisations for conditions requiring timely treatment may have significant public health consequences.
