RESUMO
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). TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04222257 (January 7, 2020). EudraCT 2019-003358-10.

BACKGROUND: Cardiac resynchronization therapy (CRT) is indicated in symptomatic heart failure (HF) patients after achieving optimal medical therapy. However, there are still a large percentage of patients who do not respond to CRT. Malnutrition is a frequent comorbidity in patients with HF, and it is associated with a poorer prognosis. Here, we evaluate the nutritional status of patients assessed by Controlling Nutritional Status (CONUT) score and its association with structural remodeling and cardiovascular events. METHODS: We investigated the effect of CONUT on HF/death in 302 consecutive patients with a CRT device implanted between 2005 and 2015 in a single tertiary center. We categorized the patients into three groups: normal nutritional status (CONUT 0-1), mild malnutrition (CONUT 2-4) and moderate-severe malnutrition (CONUTâ¯≥â¯5). Changes in nutritional status were assessed in patients with mild-to-severe malnutrition prior to CRT. RESULTS: One hundred and forty-eight patients exhibited normal nutritional status (49.0%), 99 patients exhibited mild malnutrition (32.8%) and 55 patients exhibited moderate-severe malnutrition (18.2%). CONUT scores of at least 2 were associated with higher risk of HF/death compared with CONUT 0-1. Significant left ventricular (LV) reverse remodeling was noted in patients with better nutritional status. In addition, those malnutrition patients at baseline that improved nutritional state exhibited fewer HF/death events at follow-up. CONCLUSION: CONUT score prior to CRT was an independent risk factor of death/HF and was correlated with LV reverse remodeling. Improvements in CONUT score during long-term follow-up were associated with a reduction in the rate of HF/death.
RESUMO
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.

OBJECTIVES AND BACKGROUND: Previous studies on contrast-induced nephropathy (CIN) have identified contrast volume (CV) as a risk factor. The aim of our research was to define the safe dose of contrast media based on absolute CV, maximum allowable contrast dose (MACD) and estimated glomerular filtrate rate (eGFR). METHODS AND RESULTS: A total of 940 consecutive patients with acute coronary syndrome (ACS) were enrolled. Fifty-four patients developed CIN. MACD was defined as 5*body weight/serum creatinine. When using a CV higher than MACD, CIN-risk was increased 19-fold (OR 9.810-39.307, P < 0.001). For the CV/eGFR ratio, we found that for every increase of one-tenth, CIN-risk increased by 4.9% (OR 1.037-1.061, P < 0.001). The discriminative ability of CV (C statistic = 0.626 ± 0.038) was significantly lower than for the CV/MACD (C statistic = 0.782 ± 0.036, P = 0.003) and CV/eGFR (C statistics: 0.796 ± 0.033 for MDRD-4, 0.796 ± 0.034 for Cockcroft-Gault, and 0.803 ± 0.033 for CKD-EPI; P < 0.001). There were no differences in the discriminative ability to predict CIN between the three eGFR equations. The combination of CV/MACD and CV/eGFR in a single protocol increases the positive predictive value of the Mehran risk score (40.7% vs. 8.8%) with the same sensitivity (90.7% vs. 83.3%). High doses of relative CV (CV/MACD and CV/eGFR) were also significantly associated with higher in-hospital mortality, reinfarction, and heart failure. CONCLUSIONS: A sequential protocol based on CV/MACD and CV/eGFR appropriately identified those ACS patients who developed CIN, with predictive values similar to a Mehran score, reducing the false positive rate. It is also useful to predict risk of in-hospital cardiac events regardless of GRACE score.

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.

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.

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.

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.

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.
RESUMO
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.

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.

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.

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.
RESUMO
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.

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.

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.

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 darly 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 24hours after hospital admission) may be associated with reduced all-cause mortality and cardiovascular mortality at long-term follow-up.

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.

OBJECTIVES: To describe the characteristics and long-term outcome of a large adult cohort with pulmonary atresia. BACKGROUND: Patients with pulmonary atresia (PA) are a heterogeneous population in terms of anatomy, physiology and surgical history, and their management during adulthood remains challenging. METHODS: Data on all patients with PA followed in our center between January 2000 and March 2015 were recorded. Patients were classified into the following groups: PA with ventricular septal defect (PA-VSD, 1), PA with intact ventricular septum (PA-IVS, 2) and other miscellaneous PA (PA-other, 3). RESULTS: Two-hundred twenty-seven patients with PA were identified, 66.1% female, mean age 25.5⯱â¯8.7â¯years. Over a median follow-up of 8.8â¯years, 49 (21.6%) patients had died: heart failure (nâ¯=â¯21, 42.8%) and sudden cardiac death (nâ¯=â¯8, 16.3%) were the main causes. There was no significant difference in mortality between the 3 Groups (pâ¯=â¯0.12) or between repaired and unrepaired patients in Group 1 (pâ¯=â¯0.16). Systemic ventricular dysfunction and resting oxygen saturations were the strongest predictors of mortality. Additionally, 116 (51%) patients were hospitalized, driven mainly by the need for invasive procedures, heart failure and arrhythmias. CONCLUSIONS: Adult survivors with pulmonary atresia have a high morbidity and mortality irrespective of underlying cardiac anatomy and previous reparative or palliative surgery. We present herewith predictors of outcome in adult life that may assist with their tertiary adult congenital care.

Acute coronary syndromes constitute a variety of myocardial injury presentations that include a subset of patients presenting with myocardial infarction with non-obstructive coronary arteries (MINOCA). This acute coronary syndrome differs from type 1 myocardial infarction (MI) regarding patient characteristics, presentation, physiopathology, management, treatment, and prognosis. Two-thirds of MINOCA subjects present ST-segment elevation; MINOCA patients are younger, are more often female and tend to have fewer cardiovascular risk factors. Moreover, MINOCA is a working diagnosis, and defining the aetiologic mechanism is relevant because it affects patient care and prognosis. In the absence of relevant coronary artery disease, myocardial ischaemia might be triggered by an acute event in epicardial coronary arteries, coronary microcirculation, or both. Epicardial causes of MINOCA include coronary plaque disruption, coronary dissection, and coronary spasm. Microvascular MINOCA mechanisms involve microvascular coronary spasm, takotsubo syndrome (TTS), myocarditis, and coronary thromboembolism. Coronary angiography with non-significant coronary stenosis and left ventriculography are first-line tests in the differential study of MINOCA patients. The diagnostic arsenal includes invasive and non-invasive techniques. Medical history and echocardiography can help indicate vasospasm or thrombosis, if one finite coronary territory is affected, or specify TTS if apical ballooning is present. Intravascular ultrasound, optical coherence tomography, and provocative testing are encouraged. Cardiac magnetic resonance is a cornerstone in myocarditis diagnosis. MINOCA is not a benign diagnosis, and its polymorphic forms differ in prognosis. MINOCA care varies across centres, and future multi-centre clinical trials with standardized criteria may have a positive impact on defining optimal cardiovascular care for MINOCA patients.
