Carbohydrate antigen 125-guided pre-TAVI medical optimization: impact on quality of life and clinical outcomes.

INTRODUCTION AND OBJECTIVES: Carbohydrate antigen 125 (CA125), a biomarker associated with fluid overload, has proven useful in managing diuretic therapy in heart failure. We aimed to evaluate the impact of diuretic optimization guided by CA125 before transcatheter aortic valve implantation (TAVI) on outcomes. METHODS: This prospective interventional study enrolled patients scheduled for TAVI, in whom baseline CA125 was measured 2 weeks before TAVI. Patients with CA125 ≥ 20 U/mL underwent diuretic up-titration before TAVI. Three groups were included: group I) baseline CA125 <20 U/mL; IIa) CA125 ≥ 20 U/mL that decreased after treatment, and IIb) CA125 ≥ 20 U/mL that did not decrease. The primary outcome was changes in the Kansas City Cardiomyopathy Questionnaire at 3 and 12 months. The secondary endpoint was clinical events. RESULTS: The study included 184 patients (115 group I, 46 IIa, and 23 IIb). Groups I and IIa exhibited early and sustained improvements in the Kansas City Cardiomyopathy Questionnaire (group I: 18.9 points [95%CI, 15.7-22.1; P <.001] at 90 days, and 18.1 [95%CI, 14.9-21.4, P <.001] at 1 year; group IIa: 21.1 points [95%CI, 15.4-26.7; P <.001] and 19.5 [95%CI, 13.9-25.1; P <.001] respectively). In contrast, in group IIb there was no significant improvement at 90 days (P=.12), with improvement being significant only at 1 year (17.8 points, 95%CI, 5.9-29.6; P=.003). Over a median follow-up of 20.7 months, there were 63 (27.83%) deaths or heart failure admissions. Multivariate analysis showed a lower risk of events in group I vs IIb (HR, 0.28; 95%CI, 0.14-0.58; P <.001), and IIa vs IIb (HR, 0.24; 95%CI, 0.11-0.55; P <.001). CONCLUSIONS: Patients with persistently high CA125 despite diuretic therapy pre-TAVI showed slower functional recovery and poorer clinical outcomes after TAVI.

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.

Frailty Scales for Prognosis Assessment of Older Adult Patients after Acute Myocardial Infarction.

We aimed to compare the prognostic value of two different measures, the Fried's Frailty Scale (FFS) and the Clinical Frailty Scale (CFS), following myocardial infarction (MI). We included 150 patients ≥ 70 years admitted from AMI. Frailty was evaluated on the day before discharge. The primary endpoint was number of days alive and out of hospital (DAOH) during the first 800 days. Secondary endpoints were mortality and a composite of mortality and reinfarction. Frailty was diagnosed in 58% and 34% of patients using the FFS and CFS scales, respectively. During the first 800 days 34 deaths and 137 admissions occurred. The number of DAOH decreased significantly with increasing scores of both FFS (p < 0.001) and CFS (p = 0.049). In multivariate analysis, only the highest scores (FFS = 5, CFS ≥ 6) were independently associated with fewer DAOH. At a median follow-up of 946 days, frailty assessed both by FFS and CFS was independently associated with death and MI (HR = 2.70 95%CI = 1.32-5.51 p = 0.001; HR = 2.01 95%CI = 1.1-3.66 p = 0.023, respectively), whereas all-cause mortality was only associated with FFS (HR = 1.51 95%CI = 1.08-2.10 p = 0.015). Frailty by FFS or CFS is independently associated with shorter number DAOH post-MI. Likewise, frailty assessed by either scale is associated with a higher rate of death and reinfarction, whereas FFS outperforms CFS for mortality prediction.

Intracoronary Imaging of a Synergy Megatron Stent Fracture in Ostial Right Coronary Artery.

The Synergy Megatron stent confers enhanced axial and radial forces, which makes it an ideal choice for ostial and calcified lesions. However, in this case, the stent fractured. The mechanical stress due to severe calcification at the ostium, followed by a swinging segment, probably caused hinge effect and led to a stent fracture. The fluoroscopy and stent-enhancing techniques suggest and could confirm the diagnosis, but intracoronary imaging is mandatory for anatomy characterization in order to decide treatment and optimize the result.

Long-term outcome of patients with NSTEMI and nonobstructive coronary arteries by different angiographic subtypes.

INTRODUCTION AND OBJECTIVES: Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes. METHODS: We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (< 30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortality, nonfatal myocardial infarction, and revascularization (MACE) at a median of 5 years of follow-up. RESULTS: A total of 121 patients (20.5%) showed no obstructive lesions. MINOCA was associated with a lower occurrence of MACE (P=.014; HR, 0.63; 95%CI, 0.44-0.91) and was confirmed as an independent factor in the multivariate analysis (P=.018; HR, 0.63; 95%CI, 0.43-0.92). On analysis of the separate components of the main endpoint, MINOCA was significantly associated with a lower rate of myocardial infarction and revascularization, but not with mortality. Analysis of angiographic subtypes among MINOCA patients showed that smooth coronary arteries were a statistically significant protective factor on both univariate and multivariate analysis, while mild irregularities and 30% to 49% plaques were associated with a higher risk of MACE. CONCLUSIONS: MINOCA is associated with a lower rate of MACE, driven by fewer reinfarctions and revascularizations. Within the angiographic subtypes of MINOCA, smooth arteries were independently associated with a lower number of MACE.

Factores de riesgo de muerte hospitalaria en pacientes con infarto agudo de miocardio durante la pandemia de la COVID-19 / Risk factors for in-hospital mortality in patients with acute myocardial infarction during the COVID-19 outbreak

INTRODUCCIÓN Y OBJETIVOS: A pesar de los avances en el tratamiento del infarto agudo de miocardio (IAM), este sigue presentando un pronóstico desfavorable. Hay poca evidencia acerca de la evolución de los pacientes con IAM y la enfermedad coronavírica de 2019 (COVID-19). El objetivo del estudio es describir la presentación clínica, las complicaciones y los factores predictores de mortalidad hospitalaria en pacientes con IAM durante el brote de COVID-19 en España. MÉTODOS: Se realizó un estudio de cohortes, prospectivo y multicéntrico de todos los pacientes consecutivos con IAM en tratamiento invasivo durante el brote de COVID19 (15 de marzo a 15 de abril de 2020). Se compararon las características clínicas de los pacientes positivos para COVID-19 con las de los negativos, y se evaluó el efecto de la COVID-19 en la mortalidad mediante emparejamiento por puntuación de propensión y regresión logística. RESULTADOS: Se incluyó a 187 pacientes con IAM: 111 con elevación del segmento ST y 76 sin elevación. De ellos, 32 (17%) resultaron positivos para COVID-19. Las puntuaciones GRACE y Killip-Kimball y varios marcadores inflamatorios resultaron significativamente mayores en los pacientes con COVID-19. La mortalidad total y cardiovascular fueron significativamente mayores en los pacientes con COVID-19 (el 25 frente al 3,8%; p < 0,001; y el 15,2 frente al 1,8%; p = 0,001). La puntuación GRACE > 140 (OR = 23,45; IC95%, 2,52-62,51; p = 0,005) y la COVID-19 (OR = 6,61; IC95%, 1,82-24,43; p = 0,02) resultaron factores independientes de mortalidad hospitalaria. CONCLUSIONES: Durante el brote epidémico, la puntuación GRACE elevada y la COVID19 fueron los factores independientes de mortalidad hospitalaria en los pacientes con IAM

INTRODUCTION AND OBJECTIVES: Despite advances in treatment, patients with acute myocardial infarction (AMI) still exhibit unfavorable short- and long-term prognoses. In addition, there is scant evidence about the clinical outcomes of patients with AMI and coronavirus disease 2019 (COVID-19). The objective of this study was to describe the clinical presentation, complications, and risk factors for mortality in patients admitted for AMI during the COVID-19 pandemic. METHODS: This prospective, multicenter, cohort study included all consecutive patients with AMI who underwent coronary angiography in a 30-day period corresponding chronologically with the COVID-19 outbreak (March 15 to April 15, 2020). Clinical presentations and outcomes were compared between COVID-19 and non-COVID-19 patients. The effect of COVID-19 on mortality was assessed by propensity score matching and with a multivariate logistic regression model. RESULTS: In total, 187 patients were admitted for AMI, 111 with ST-segment elevation AMI and 76 with non-ST-segment elevation AMI. Of these, 32 (17%) were diagnosed with COVID-19. GRACE score, Killip-Kimball classification, and several inflammatory markers were significantly higher in COVID-19-positive patients. Total and cardiovascular mortality were also significantly higher in COVID-19-positive patients (25% vs 3.8% [P < .001] and 15.2% vs 1.8% [P = .001], respectively). GRACE score > 140 (OR, 23.45; 95%CI, 2.52-62.51; P = .005) and COVID-19 (OR, 6.61; 95%CI, 1.82-24.43; P = .02) were independent predictors of in-hospital death. CONCLUSIONS: During this pandemic, a high GRACE score and COVID-19 were independent risk factors associated with higher in-hospital mortality

Contemporary differences between men and women with acute coronary syndromes: CIAM multicenter registry.

AIM: Differences exist in the diagnosis and treatment of acute coronary syndrome (ACS) between men and women. However, recent advancements in the management of ACSs might have attenuated this sex gap. We evaluated the status of ACS management in a multicenter registry in 10 tertiary Spanish hospitals. METHODS: We enrolled 1056 patients in our study, including only those with type 1 myocardial infarctions or unstable angina presumably not related to a secondary cause in an 'all-comers' design. RESULTS: The women enrolled (29%) were older than men (71.0 ±â€Š12.8 vs. 64.0 ±â€Š12.3, P = 0.001), with a higher prevalence of hypertension (71.0 vs. 56.5%, P < 0.001), insulin-treated diabetes (13.7 vs. 7.9%, P = 0.003), dyslipidemia (62.2 vs. 55.3%, P = 0.038), and chronic kidney disease (16.9 vs. 9.1%, P = 0.001). Women presented more frequently with back or arm pain radiation (57.3 vs. 49.7%, P = 0.025), palpitations (5.9 vs. 2.0%, P = 0.001), or dyspnea (33.0 vs. 19.4%, P = 0.001). ACS without significant coronary stenosis was more prevalent in women (16.8 vs. 8.1%, P = 0.001). There were no differences in percutaneous revascularization rates, but drug-eluting stents were less frequently employed in women (75.4 vs. 67.8%, P = 0.024); women were less often referred to a cardiac rehabilitation program (19.9 vs. 33.9%, P = 0.001). There were no significant differences in in-hospital complications such as thrombosis or bleeding. CONCLUSION: ACS presenting with atypical symptoms and without significant coronary artery stenosis is more frequent in women. Selection of either an invasive procedure or conservative management is not influenced by sex. Cardiac rehabilitation referral on discharge is underused, especially in women.

Iron deficiency and long-term mortality in elderly patients with acute coronary syndrome.

AIM: We evaluated the relationship between iron deficiency (ID) and long-term mortality risk in elderly patients with acute coronary syndrome (ACS). METHODS: In this prospective observational study, we included 252 patients older than 65 years with ACS. Transferrin saturation (TSAT) and ferritin were collected before discharge. RESULTS: Mean age, hemoglobin and GRACE score were 78 ± 7 years, 12.4 ± 1.8 g/dl and 138.8 ± 25.3, respectively, 112(44.4%) patients were women, and 151(59.9%) presented ID. During the follow-up, 121 (48%) patients died. Mortality rates among TSAT quartiles were: 2.38, 1.60, 0.90 and 0.95 × 10 person-years for Q1TSAT to Q4TSAT, respectively (p < 0.001) and did not differ across ferritin quartiles (p = 0.601), whereas ID definition was borderline associated (p = 0.060). Adjusted TSAT levels remained inverse, nonlinearly associated with long-term mortality risk (p < 0.001), with an exponential increased-risk from values about 20% and below. CONCLUSION: Lower TSAT levels were independently associated with increased mortality risk in these patients.
