Classification tree obtained by artificial intelligence for the prediction of heart failure after acute coronary syndromes. / Árboles de clasificación obtenidos mediante inteligencia artificial para la predicción de insuficiencia cardiaca tras el síndrome coronario agudo.

BACKGROUND: Coronary heart disease is the leading cause of heart failure (HF), and tools are needed to identify patients with a higher probability of developing HF after an acute coronary syndrome (ACS). Artificial intelligence (AI) has proven to be useful in identifying variables related to the development of cardiovascular complications. METHODS: We included all consecutive patients discharged after ACS in two Spanish centers between 2006 and 2017. Clinical data were collected and patients were followed up for a median of 53months. Decision tree models were created by the model-based recursive partitioning algorithm. RESULTS: The cohort consisted of 7,097 patients with a median follow-up of 53months (interquartile range: 18-77). The readmission rate for HF was 13.6% (964 patients). Eight relevant variables were identified to predict HF hospitalization time: HF at index hospitalization, diabetes, atrial fibrillation, glomerular filtration rate, age, Charlson index, hemoglobin, and left ventricular ejection fraction. The decision tree model provided 15 clinical risk patterns with significantly different HF readmission rates. CONCLUSIONS: The decision tree model, obtained by AI, identified 8 leading variables capable of predicting HF and generated 15 differentiated clinical patterns with respect to the probability of being hospitalized for HF. An electronic application was created and made available for free.

Differential prognosis of patients that are candidates for standard, short or prolonged dual antiplatelet treatment discharged after an acute coronary syndrome.

BACKGROUND: Current evidence supports the efficacy of prolonged dual antiplatelet treatment (DAPT) for patients at high-ischemic risk and low bleeding risk as well as the efficacy and safety of short DAPT in high-bleeding risk (HBR) patients. METHODS: We evaluated patterns of DAPT candidates in all patients discharged in 2 hospitals after an acute coronary syndrome (ACS). Patients categorized in 3 groups: 1) short-DAPT candidates if they met 1 major o 2 minor criteria for HBR, by the 2019 ARC-HBR criteria; 2) prolonged-DAPT candidates if were not HBR and had recurrent ACS, complex percutaneous coronary interventions or diabetes; 3) standard 12 months DAPT if were not include in the previous 2 groups. Major bleeding (MB) was registered according to 3 or 5 of the BARC consortium definitions. RESULTS: We included 8252 patients and 3215 (39 %) were candidates for abbreviated DAPT, 3119 (37.8 %) for prolonged DAPT, and 1918 (23.2 %) for 12 m DAPT. Relevant differences were observed between the 3 categories beyond the bleeding risk. Median follow-up was 57 months. Multivariate analysis identified higher risk of all-cause mortality (HR: 1.96 95 % CI 1.45-2.67; p < 0.001), cardiovascular mortality (HR: 2.10 95 % CI 1.39-3.19; p < 0.011), MACE (HR: 1.69 95 % 1.50-2.02; p < 0.001) and MB (sHR: 3.41 95 % CI 1.45-8.02; p = 0.005) in candidates to short DAPT. Candidates to prolonged DAPT had higher risk of MACE (HR: 1.17 95 % CI 1.02-1.35; p = 0.027). CONCLUSIONS: Almost two thirds of patients discharged after an ACS would be candidates for short or prolonged DAPT and these patients are at higher risk of MACE and mortality.

Remnant cholesterol in patients admitted for acute coronary syndromes.

BACKGROUND: Remnant cholesterol has been identified as one of leading lipid values associated with the incidence of coronary heart disease. There is scarce evidence on its distribution and prognostic value in acute coronary syndrome (ACS) patients. METHODS AND RESULTS: We included all consecutive patients admitted for ACS in two different centres. Remnant cholesterol was calculated by the equation: total cholesterol minus LDL cholesterol minus HDL cholesterol, and values ≥30 were considered high. Among the 7479 patients, median remnant cholesterol level was 28 mg/dL (21-39), and 3429 (45.85%) patients had levels ≥30 mg/dL. Age (r: -0.29) and body mass index (r: 0.44) were the variables more strongly correlated. At any given age, patients with overweigh or obesity had higher levels. In-hospital mortality was 3.75% (280 patients). Remnant cholesterol was not associated to higher in-hospital mortality risk (odds ratio: 0.89; P = 0.21). After discharge (median follow-up of 57 months), an independent and linear risk of all-cause mortality and heart failure (HF) associated to cholesterol remnant levels was observed. Remnant cholesterol levels >60 mg/dL were associated to higher risk of mortality [hazard ratio (HR): 1.49 95% CI 1.08-2.06; P = 0.016], cardiovascular mortality (HR: 1.49 95% CI 1.08-2.06; P = 0.016), and HF re-admission (sub-HR: 1.55 95% CI 1.14-2.11; P = 0.005). CONCLUSIONS: Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is inversely correlated with age and positively with body mass index. Remnant cholesterol levels were not associated to higher in-hospital mortality risk, but they were associated with higher long-term risk of mortality and HF.

Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is related to body mass index and negatively with age. Remnant cholesterol it is not associated to higher in-hospital mortality risk, but it confers higher long-term risk of mortality and heart failure.

Applicability of the Zwolle score for selection of very high-risk ST-elevation myocardial infarction patients treated with primary angioplasty.

The Zwolle risk score was designed to stratify in-hospital mortality risk of ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (pPCI) and for decision-making in the unit where patients are admitted. We assessed the accuracy of Zwolle risk score for in-hospital mortality estimation compared with the GRACE score in all patients (n = 4446) admitted for STEMI in 3 university hospitals. Only one fourth of the patients were classified as high-risk by the Zwolle risk score vs 60% by the GRACE score. In-hospital mortality was 10.6%. A statistically significant increase in in-hospital mortality, adjusted by age, gender, and revascularization, was observed with both scores. The assessment of the optimal cut-off points verified the accuracy of Zwolle score ≥4 as optimal threshold for high-risk categorization. In contrast, GRACE score ≥140 had very low specificity as well as percentage of patients correctly classified; GRACE score ≥175 was fairly better. The reclassification index of the Zwolle score after applying the GRACE score was 35.5%. Selection of high-risk STEMI patients treated with pPCI based on the Zwolle risk score has higher specificity than the GRACE score and might be useful in clinical practice.

An electronic consultation program impacts on heart failure patients' prognosis: implications for heart failure care.

AIMS: e-consults are asynchronous, clinician-to-clinician exchanges that answer focused, non-urgent, patient-specific questions using the electronic medical record. We instituted an e-consultation programme (2013-2019) for all general practitioners (GPs) referrals to cardiologists that preceded patients' in-person consultations when considered. In our study, we aimed to analyse the clinical characteristics, 1 year prognosis and the prognostic determinants of patients with a previous diagnosis of HF referred for an e-consult, categorized by their previous HF-related hospitalization status (recent hospitalization, <1 year before; remote hospitalization, >1 year before or never been hospitalized because of HF), and to analyse the impact of reducing the time elapsed between e-consultation and response by the cardiologist in terms of prognosis. METHODS AND RESULTS: Epidemiological and clinical data were obtained from 4851 HF patients referred by GPs to the cardiology department for an e-consultation 2013 and 2020. The delay of time to e-consults were solved was 8.6 + 8.6 days with 84.3% solved in <14 days. For the 1 year prognosis evaluation after the e-consult were assessed the cardiovascular hospitalizations, HF-related hospitalizations, HF-related mortality, cardiovascular mortality, and all-cause mortality. Compared with the group without a previous hospitalization, patients with recent and remote HF hospitalization were at higher risk of a new HF-related hospitalization (OR: 19.41 [95% CI: 12.95-29.11]; OR: 8.44 [95% CI: 5.14-13.87], respectively), HF-related mortality (OR: 2.47 [95% CI: 1.43-4.27]; OR: 1.25 [95% CI: 0.51-3.06], respectively), as well as cardiovascular hospitalizations and mortality and all-cause mortality. Reduction in the time elapsed because e-consultation was solved was associated with lower risk of HF-related mortality (OR: 0.94 [95% CI: 0.89-0.99]), cardiovascular mortality (OR: 0.96 [95% CI: 0.93-0.98]), and all-cause mortality (OR: 0.98 [95% CI: 0.97-1.00]). CONCLUSIONS: A clinician-to-clinician e-consultation programme between GPs and cardiologists in patients with HF allows to solve the demand of care in around 25% e-consults without an in-person consultation; the patients with a previous history of HF-related hospitalization showed a worse 1 year outcome. A reduction in the time elapsed because e-consultation was solved was associated with a mortality reduction.

Prognostic impact of renal function trajectories in patients with STEMI and kidney dysfunction undergoing primary percutaneous coronary intervention: An analysis of ten years all-comers registry.

BACKGROUND: Renal dysfunction in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) indicates a poor long-term prognosis. However, the prognostic value of the improvement or stabilisation of renal function during follow-up has not yet been assessed. This study aimed to investigate the long-term predictive impact of the improvement or stabilisation of renal function after one year of follow-up in patients with STEMI undergoing pPCI with renal dysfunction at discharge. METHODS: This prospective, single-centre cohort study included 2170 consecutive patients with STEMI who underwent pPCI. The glomerular filtration rate (GFR) was determined at hospital discharge and one-year follow-up. The median clinical follow-up was 72 months. RESULTS: Among the 2004 patients, 393 (19.6%) had a GFR <60 ml/min, and 1611 (80.4%) had a GFR ≥ 60 ml/min at discharge. Among patients with GFR <60 ml/min, data at one-year follow-up were available for 342. Of these patients, 127 (32%) showed improvement in renal function (defined as improvement in the Kidney Disease Improving Global Outcomes (KDIGO) chronic kidney disease (CKD) classification), 47 (12%) showed worsening of renal function (defined as worsening of the KDIGO CKD classification), and 168 (43%) showed no category changes. Improvement or stabilisation of GFR at one year of follow-up was associated with a reduction of major adverse cardiovascular events (MACE) [HR 0.51, 95% CI: 0.35-0.75, p = 0.001] and all-cause mortality [HR 0.54, 95% CI: 0.34-0.84, p = 0.007] during follow-up. CONCLUSIONS: The improvement or stabilisation of renal function at one-year follow-up in patients with STEMI and renal dysfunction is associated with a better long-term prognosis.

Longer-Term Results of a Universal Electronic Consultation Program at the Cardiology Department of a Galician Healthcare Area.

BACKGROUND: Telemedicine models play a key role in organizing the growing demand for care and healthcare accessibility, but there are no described longer-term results in health care. Our objective is to assess the longer-term results (delay time in care, accessibility, and hospital admissions) of an electronic consultation (e-consultation) outpatient care program. METHODS: Epidemiological and clinical data were obtained from the 41 258 patients referred by primary care to the cardiology department from January 1, 2010, to December 31, 2019. Until 2012, all patients were attended in an in-person consultation (2010-2012). In 2013, we instituted an e-consultation program (2013-2019) for all primary care referrals to cardiologists that preceded patients' in-person consultations when considered. We used an interrupted time series regression approach to investigate the impact of the e-consultation on (1) delay time (days) in care and (2) hospital admissions. We also analyzed (3) total number and referral rate (population-adjusted referred rate) in both periods (in-person consultation and e-consultation), and (4) the accessibility was measured as number of consultations and variation according to distance from municipality and reference hospital. RESULTS: During the e-consultation, the demand increased (7.2±2.4% versus 10.1±4.8% per 1000 inhabitants, P<0.001), and referrals from different areas were equalized. The reduction in delay to consultation during the in-person consultation (-0.96 [95% CI, -0.951 to -0.966], P<0.001) was maintained with e-consultations (-0.064 [95% CI, 0.043-0.085], P<0.001). After the implementation of e-consultation, we observed that the increasing of hospital admission observed in the in-person consultation (incidence rate ratio, 1.011 [95% CI, 1.003-1.018]), was stabilized (incidence rate ratio, 1.000 [95% CI, 0.985-1.015]; P=0.874). CONCLUSIONS: Implementing e-consultations in the outpatient management model may improve accessibility of care for patients furthest from the referral hospital. After e-consultations were implemented, the upward trend of hospital admissions observed during the in-person consultation period was stabilized with a slight downward trend.

Should PRECISE-DAPT be included for long-term prognostic stratification of diabetic patients with NSTEACS?

AIMS: There are insufficient data regarding risk scores validation in patients with diabetes mellitus and non-ST elevation acute coronary syndrome (NSTEACS). We performed a diabetes mellitus-specific analysis of cardiovascular outcomes after NSTEACS. We tested the predictive power of the Global Registry of Acute Coronary Events (GRACE) and PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent Dual Anti-Platelet Therapy (PRECISE-DAPT) scores. METHODS: This work is a retrospective analysis that included 7,415 consecutive NSTEACS patients from two Spanish Universitarian hospitals between the years 2003 and 2017. The area under the ROC curve among with and without diabetes mellitus patients was calculated, to evaluate the predictive power of both scores.  RESULTS: Among the study participants, 2124 patients (28.0%) were diabetic. The median follow-up was 54,3 months (IQR 24,7-80,0 months). Diabetic patients were more women (30.5% vs. 25.7%) and older (70.0 ± 10.8 vs. 65.3 ± 13.2 years old); they had higher GRACE (146 ± 36 vs. 137 ± 36), PRECISE-DAPT (15 ± 7 vs. 18 ± 9) at admission. Early invasive coronary angiography (≤ 24 h after admission) was performed more frequently in non-diabetic. We tested the predictive power of the GRACE and PRECISE-DAPT risk scores among diabetic and non-diabetic. PRECISE-DAPT risk score showed a good predictive power for all-cause mortality, cardiovascular mortality and MACE in diabetic admitted with NSTEACS, without differences compared to non-diabetic. CONCLUSIONS: PRECISE-DAPT risk score has an appropriate predictive power in diabetic patients admitted with NSTEACS compared to non-diabetic NSTEACS. However, GRACE would be predictive worse in diabetic during long-term follow-up in a large contemporary registry.

Early angiography in elderly patients with non-ST-segment elevation acute coronary syndrome: The cardio CHUS-HUSJ registry.

BACKGROUND: In elderly patients with non-ST elevation acute coronary syndrome (NSTEACS), while routine invasive management is established in high-risk NSTEACS patients, there is still uncertainty regarding the optimal timing of the procedure. METHODS: This study analyzes the association of early coronary angiography with all-cause mortality, cardiovascular mortality, heart failure (HF) hospitalization, and major adverse cardiovascular events (MACE) in patients older than 75 years old with NSTEACS. This retrospective observational study included 7811 consecutive NSTEACS patients who were examined between the years 2003 and 2017 at two Spanish university hospitals. There were 2290 patients older than 75 years old. We compared their baseline characteristics according to the early invasive strategy used (coronarography ≤24 h vs. coronarography >24 h) after the diagnosis of NSTEACS. RESULTS: Among the study participants, 1566 patients (68.38%) underwent early invasive coronary intervention. The mean follow-up period was 46 months (interquartile range 18-71 months). This association was also maintained after propensity score matching: early invasive strategy was significantly related to lower all-cause mortality [HR 0.61 (95% CI 0.51-0.71)], cardiovascular mortality [HR 0.52 (95% CI 0.43-0.63)], and MACE [HR 0.62 (CI 95% 0.54-0.71)]. CONCUSIONS: In a contemporary real-world registry of elderly NSTEACS patients, early invasive management significantly reduced all-cause mortality, cardiovascular mortality, and MACE during long-term follow-up. BRIEF SUMMARY: In this real-world retrospective observational study that included 2451 patients older than 75 years old, 1566 patients (68.38%) underwent early invasive coronary intervention. After performing a propensity score matching, the early invasive strategy was still associated with lower all-cause mortality [HR (hazard ratio) 0.61, 95% CI (95% confidence interval) (0.51-0.71)], cardiovascular mortality [HR 0.52 (95%CI 0.43-0.63)], and MACE [HR 0.62 (95%CI 0.54-0.71)] during long-term follow-up.

Prognostic impact of left ventricular ejection fraction recovery in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention: analysis of an 11-year all-comers registry.

AIMS: Left ventricular ejection fraction (LVEF) recovery after an ST-segment elevation myocardial infarction (STEMI) identifies a group of patients with a better prognosis. However, the association between long-term outcomes and LVEF recovery among patients with STEMI undergoing primary percutaneous coronary intervention (PCI) has not yet been well investigated. Our study aims to detect differences in long-term all-cause and cardiovascular mortality between patients who recover LVEF at 1-year post-PCI and those who do not, and search for predictors of LVEF recovery. METHODS AND RESULTS: This is a retrospective, single-centre study of 2170 consecutive patients admitted for STEMI in which primary PCI is performed. LVEF was determined at admission and at 1-year follow-up. The primary outcomes were long-term all-cause and cardiovascular mortality. Among the 2168 patients with baseline LVEF data, 822 (38%) had a LVEF < 50% and 1346 (62%) ≥ 50%. Among those with LVEF < 50%, LVEF data at 1-year were available in 554, and 299 (54.0%) presented with complete recovery (LVEF ≥ 50%). LVEF recovery was associated with a reduction in long-term all-cause and cardiovascular mortality (P < 0.0001). Female sex, treatment with ACEIs, lower creatinine levels, infarct-related artery different from the left main or left anterior descendent artery, and absence of prior ischaemic heart disease were independently associated with LVEF recovery. CONCLUSIONS: Nearly 40% of patients with STEMI undergoing primary PCI presented with LVEF depression at hospital admission. Among them, LVEF recovery at 1-year occurred in more than 50% and was independently associated with a significant decrease in long-term all-cause and cardiovascular mortality.

Long-term cardiac reverse remodeling after cardiac resynchronization therapy.

INTRODUCTION: The benefit of cardiac resynchronization therapy (CRT) in heart failure (HF) patients with reduced left ventricular ejection fraction (LVEF) have been observed in the first year. However, there are few data on long-term follow-up and the effect of changes of LVEF on mortality. This study aimed to assess the LV remodeling after CRT implantation and the probable effect of changes in LVEF with repeated measures on mortality over time in a real-world registry. METHODS: Among our cohort of 328 consecutive CRT patients, mixed model effect analysis have been made to describe the temporal evolution of LVEF and LVESV changes over time up with several explanatory variables. Besides, the effect of LVEF along time on the probability of mortality was evaluated using joint modeling for longitudinal and survival data. RESULTS: The study population included 328 patients (253 men; 70.2 ± 9.5 years) in 4.2 (2.9) years follow-up. There was an increase in LVEF of 11% and a reduction in LVESV of 42 mL during the first year. These changes are more important during the first year, but slight changes remain during the follow-up. The largest reduction in LVESV occurred in patients with left bundle branch block (LBBB) and the smallest reduction in patients with NYHA IV. The smallest increase in LVEF was an ischemic etiology, longer QRS, and LV electrode in a nonlateral vein. Besides, the results showed that the LVEF profiles taken during follow-up after CRT were associated with changes in the risk of death. CONCLUSION: Reverse remodeling of the left ventricle is observed especially during the first year, but it seems to be maintained later after CRT implantation in a contemporary cohort of patients. Longitudinal measurements could give us additional information at predicting the individual mortality risk after adjusting by age and sex compared to a single LVEF measurement after CRT.

Insuficiencia cardiaca de novo tras un síndrome coronario agudo en pacientes sin insuficiencia cardiaca ni disfunción ventricular izquierda / New-onset heart failure after acute coronary syndrome in patients without heart failure or left ventricular dysfunction

Introducción y objetivos: La cardiopatía isquémica es la primera causa de insuficiencia cardiaca. Nuestro objetivo es analizar el riesgo de insuficiencia cardiaca tras un síndrome coronario agudo en pacientes sin insuficiencia cardiaca previa ni disfunción ventricular izquierda. Métodos: Estudio prospectivo de pacientes consecutivos ingresados por síndrome coronario agudo en 2 hospitales. La incidencia de insuficiencia cardiaca se analizó considerando la muerte como evento competitivo. Resultados: Se incluyó a 5.962 pacientes, y 567 (9,5%) tuvieron al menos 1 reingreso por insuficiencia cardiaca aguda. La mediana de seguimiento fue 63 meses y la mediana de tiempo hasta el reingreso por insuficiencia cardiaca 27,1 meses. La incidencia acumulada de insuficiencia cardiaca fue superior que la de muerte en los primeros 7 años tras el alta. La edad, la diabetes, la cardiopatía isquémica previa, una escala GRACE> 140, la enfermedad arterial periférica, la disfunción renal, la hipertensión arterial y la fibrilación auricular se asociaron con mayor riesgo de reingreso por insuficiencia cardiaca; el tratamiento médico óptimo se asoció con menor riesgo. La incidencia de insuficiencia cardiaca en el primer año fue del 2,73% y no se hallaron variables protectoras. Una sencilla escala de riesgo de insuficiencia cardiaca predijo el riesgo de reingreso por insuficiencia cardiaca. Conclusiones: Uno de cada 10 pacientes dados de alta tras un síndrome coronario agudo sin haber tenido antes insuficiencia cardiaca o disfunción ventricular sufrió insuficiencia cardiaca de novo y el riesgo es superior que el de muerte. Una sencilla escala clínica permite estimar el riesgo individual de reingreso por insuficiencia cardiaca, incluso en pacientes que no han tenido antes insuficiencia cardiaca ni disfunción ventricular izquierda.

Introduction and objectives: Coronary heart disease is the leading cause of heart failure (HF). The aim of this study was to assess the risk of readmission for HF in patients with acute coronary syndrome without previous HF or left ventricular dysfunction. Methods: Prospective study of consecutive patients admitted for acute coronary syndrome in 2 institutions. Risk factors for HF were analyzed by competing risk regression, taking all-cause mortality as a competing event. Results: We included 5962 patients and 567 (9.5%) experienced at least 1 hospital readmission for acute HF. Median follow-up was 63 months and median time to HF readmission was 27.1 months. The cumulative incidence of HF was higher than mortality in the first 7 years after hospital discharge. A higher risk of HF readmission was associated with age, diabetes, previous coronary heart disease, GRACE score> 140, peripheral arterial disease, renal dysfunction, hypertension and atrial fibrillation; a lower risk was associated with optimal medical treatment. The incidence of HF in the first year of follow-up was 2.73% and no protective variables were found. A simple HF risk score predicted HF readmissions risk. Conclusions: One out of 10 patients discharged after an acute coronary syndrome without previous HF or left ventricular dysfunction had new-onset HF and the risk was higher than the risk of mortality. A simple clinical score can estimate individual risk of HF readmission even in patients without previous HF or left ventricular dysfunction. (AU)

Prognostic benefit from an early invasive strategy in patients with non-ST elevation acute coronary syndrome (NSTEACS): evaluation of the new risk stratification in the NSTEACS European guidelines.

OBJECTIVES: The objective of our work is to evaluate the prognostic benefit of an early invasive strategy in patients with high-risk NSTACS according to the recommendations of the 2020 clinical practice guidelines during long-term follow-up. METHODS: This retrospective observational study included 6454 consecutive NSTEACS patients. We analyze the effects of early coronary angiography (< 24 h) in patients with: (a) GRACE risk score > 140 and (b) patients with "established NSTEMI" (non ST-segment elevation myocardial infarction defined by an increase in troponins) or dynamic ST-T-segment changes with a GRACE risk score < 140. RESULTS: From 2003 to 2017, 6454 patients with "new high-risk NSTEACS" were admitted, and 6031 (93.45%) of these underwent coronary angiography. After inverse probability of treatment weighting, the long-term cumulative probability of being free of all-cause mortality, cardiovascular mortality and MACE differed significantly due to an early coronary intervention in patients with NSTEACS and GRACE > 140 [HR 0.62 (IC 95% 0.57-0.67), HR 0.62 (IC 95% 0.56-0.68), HR 0.57 (IC 95% 0.53-0.61), respectively]. In patients with NSTEACS and GRACE < 140 with established NSTEMI or ST/T-segment changes, the benefit of the early invasive strategy is only observed in the reduction of MACE [HR 0.62 (IC 95% 0.56-0.68)], but not for total mortality [HR 0.96 (IC 95% 0.78-1.2)] and cardiovascular mortality [HR 0.96 (IC 95% 0.75-1.24)]. CONCLUSIONS: An early invasive management is associated with reduced all-cause mortality, cardiovascular mortality and MACE in NSTEACS with high GRACE risk score. However, this benefit is less evident in the subgroup of patients with a GRACE score < 140 with established NSTEMI or ST/T-segment changes.

New-onset heart failure after acute coronary syndrome in patients without heart failure or left ventricular dysfunction.

INTRODUCTION AND OBJECTIVES: Coronary heart disease is the leading cause of heart failure (HF). The aim of this study was to assess the risk of readmission for HF in patients with acute coronary syndrome without previous HF or left ventricular dysfunction.

Risk factors for HF were analyzed by competing risk regression, taking all-cause mortality as a competing event. RESULTS: We included 5962 patients and 567 (9.5%) experienced at least 1 hospital readmission for acute HF. Median follow-up was 63 months and median time to HF readmission was 27.1 months. The cumulative incidence of HF was higher than mortality in the first 7 years after hospital discharge. A higher risk of HF readmission was associated with age, diabetes, previous coronary heart disease, GRACE score> 140, peripheral arterial disease, renal dysfunction, hypertension and atrial fibrillation; a lower risk was associated with optimal medical treatment. The incidence of HF in the first year of follow-up was 2.73% and no protective variables were found. A simple HF risk score predicted HF readmissions risk.

A simple clinical score can estimate individual risk of HF readmission even in patients without previous HF or left ventricular dysfunction.

Short-course antibiotic regimen compared to conventional antibiotic treatment for gram-positive cocci infective endocarditis: randomized clinical trial (SATIE).

BACKGROUND: Most serious complications of infective endocarditis (IE) appear in the so-called "critical phase" of the disease, which represents the first days after diagnosis. The majority of patients overcoming the acute phase has a favorable outcome, yet they remain hospitalized for a long period of time mainly to complete antibiotic therapy. The major hypothesis of this trial is that in patients with clinically stable IE and adequate response to antibiotic treatment, without signs of persistent infection, periannular complications or metastatic foci, a shorter antibiotic time period would be as efficient and safe as the classic 4 to 6 weeks antibiotic regimen. METHODS: Multicenter, prospective, randomized, controlled open-label, phase IV clinical trial with a non-inferiority design to evaluate the efficacy of a short course (2 weeks) of parenteral antibiotic therapy compared with conventional antibiotic therapy (4-6 weeks). SAMPLE: patients with IE caused by gram-positive cocci, having received at least 10 days of conventional antibiotic treatment, and at least 7 days after surgery when indicated, without clinical, analytical, microbiological or echocardiographic signs of persistent infection. Estimated sample size: 298 patients. INTERVENTION: Control group: standard duration antibiotic therapy, (4 to 6 weeks) according to ESC guidelines recommendations. Experimental group: short-course antibiotic therapy for 2 weeks. The incidence of the primary composite endpoint of all-cause mortality, unplanned cardiac surgery, symptomatic embolisms and relapses within 6 months after the inclusion in the study will be prospectively registered and compared. CONCLUSIONS: SATIE will investigate whether a two weeks short-course of intravenous antibiotics in patients with IE caused by gram-positive cocci, without signs of persistent infection, is not inferior in safety and efficacy to conventional antibiotic treatment (4-6 weeks).

Sex-related differences in long-term mortality and heart failure in a contemporary cohort of patients with NSTEACS. The cardiochus-HSUJ registry.

INTRODUCTION AND OBJECTIVES: There is insufficient data regarding sex-related prognostic differences in patients with a non-ST elevation acute coronary syndrome (NSTEACS). We performed a sex-specific analysis of cardiovascular outcomes after NSTEACS using a large contemporary cohort of patients from two tertiary hospitals. METHODS: This work is a retrospective analysis from a prospective registry, that included 5,686 consecutive NSTEACS patients from two Spanish University hospitals between the years 2005 and 2017. We performed a propensity score matching to obtain a well-balanced subset of individuals with the same clinical characteristics, resulting in 3,120 patients. Cox regression models performed survival analyses once the proportional risk test was verified. RESULTS: Among the study participants, 1,572 patients (27.6%) were women. The mean follow-up was 60.0 months (standard deviation of 32 months). Women had a higher risk of cardiovascular mortality compared with men (OR (Odds ratio) 1.27, CI (confidence interval) 95% 1.08-1.49), heart failure (HF) hospitalization (OR 1.39, CI 95% 1.18-1.63) and risk of all-cause mortality (OR 1.10, CI 95% 1.08-1.49). After a propensity score matching, female gender was associated with a significant reduction in the risk of total mortality (OR 0.77, CI 95% 0.65-0.90) with a similar risk of cardiovascular mortality (OR 0.86, CI 0.71-1.03) and HF hospitalization (OR 0.92, CI 95% 0.68-1.23). After baseline adjustment, the risk of all-cause mortality and cardiovascular mortality was lower in women, whereas the risk of HF remained similar among sexes. CONCLUSIONS: In a contemporary cohort of patients with NSTEACS, women are at similar risk of developing early and late HF admissions, and have better survival compared with men, with a lower risk of all-cause mortality and cardiovascular mortality. The implementation of NSTEACS guideline recommendations in women, including early revascularization, seems to be accompanied by improved early and long-term prognosis.

INTRODUCCIÓN Y OBJETIVOS: El objetivo de este estudio es analizar la asociación de la coronariografía precoz con la mortalidad por cualquier causa y la mortalidad cardiovascular en los pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST) utilizando una gran cohorte contemporánea de pacientes con SCASEST de 2 hospitales terciarios españoles. MÉTODOS: Este estudio observacional retrospectivo incluyó a 5.673 pacientes con SCASEST consecutivos de 2 hospitales españoles entre los años 2005 y 2016. Se emparejó por puntuación de propensión para obtener un subconjunto bien equilibrado de pacientes con la misma probabilidad de una coronariografía temprana, lo que dio como resultado 3.780 pacientes. RESULTADOS: Entre los participantes del estudio, se realizó una coronariografía precoz a solo 2.087 pacientes (40,9%). La mediana de seguimiento fue de 59,0 [intervalo intercuartílico, 25,0-80,0] meses. La mortalidad por cualquier causa fue del 19,0%; la mortalidad cardiovascular, del 12,8%, y el 51,1% de los pacientes sufrieron al menos 1 evento cardiovascular mayor (mortalidad, infarto agudo de miocardio, hospitalización por insuficiencia cardiaca o revascularización no planeada) en el seguimiento. Después de emparejar por puntuación de propensión, la revascularización temprana se asoció con una mortalidad significativamente menor (HR=0,79; IC95%, 0,62-0,98), en los pacientes con SCASEST de alto riesgo. La coronariografía precoz mostró una tendencia inversa no significativa en los pacientes con puntuación GRACE <140. CONCLUSIONES: En los pacientes con SCASEST de alto riesgo (puntuación GRACE ≥ 140) de un registro contemporáneo de la práctica clínica, la coronariografía temprana (las primeras 24 h tras el ingreso hospitalario) puede estar asociada con una reducción de la mortalidad por cualquier causa y la mortalidad cardiovascular en el seguimiento a largo plazo

INTRODUCTION AND OBJECTIVES: This study sought to analyze the association of early coronary angiography with all-cause mortality and cardiovascular mortality in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) using a large contemporary cohort of patients with NSTEACS from 2 Spanish tertiary hospitals. METHODS: This retrospective observational study included 5673 consecutive NSTEACS patients from 2 Spanish hospitals between 2005 and 2016. We performed propensity score matching to obtain a well-balanced subset of patients with the same probability of undergoing an early strategy, resulting in 3780 patients. Survival analyses were performed by Cox regression models once proportional risk test were verified. RESULTS: Among the study participants, only 2087 patients (40.9%) underwent early invasive coronary angiography. The median follow-up was 59.0 months [interquartile range, 25.0-80.0 months]. All-cause mortality was 19.0%, cardiovascular mortality was 12.8%, and 51.1% patients experienced at least 1 major cardiovascular adverse event in the follow-up. After propensity score matching, the early strategy was associated with significantly lower mortality (hazard ratio: 0.79; 95% confidence interval 0.62-0.98) in high-risk NSTEACS patients. The early strategy showed a nonsignificant inverse tendency in patients with GRACE score <140. CONCLUSIONS: In high-risk (GRACE score ≥ 140) NSTEACS patients in a contemporary real-world registry, early coronary angiography (first 24 hours after hospital admission) may be associated with reduced all- cause mortality and cardiovascular mortality at long-term follow-up
