RESUMEN
BACKGROUND: Hypertension has been known to increase the risk of obstetric complications. Recently, the American College of Cardiology endorsed lower thresholds for hypertension as systolic blood pressure of 130-139 mmHg or diastolic blood pressure 80-89 mmHg. However, there is a paucity of information regarding the impact of pre-pregnancy blood pressure on pregnancy outcomes. We aimed to evaluate the effect of pre-pregnancy blood pressure on maternal and neonatal complications. METHODS: In this nationwide, population based study, pregnant women without history of hypertension and pre-pregnancy blood pressure < 140/90 mmHg were enrolled. The primary outcome of composite morbidity was defined as any of the followings: preeclampsia, placental abruption, stillbirth, preterm birth, or low birth weight. RESULTS: A total of 375,305 pregnant women were included. After adjusting for covariates, the risk of composite morbidity was greater in those with stage I hypertension in comparison with the normotensive group (systolic blood pressure, odds ratio = 1.68, 95% CI: 1.59 - 1.78; diastolic blood pressure, odds ratio = 1.56, 95% CI: 1.42 - 1.72). There was a linear association between pre-pregnancy blood pressure and the primary outcome, with risk maximizing at newly defined stage I hypertension and with risk decreasing at lower blood pressure ranges. CONCLUSIONS: 'The lower, the better' phenomenon was still valid for both maternal and neonatal outcomes. Our results suggest that the recent changes in diagnostic thresholds for hypertension may also apply to pregnant women. Therefore, women with stage I hypertension prior to pregnancy should be carefully observed for adverse outcomes.

Severe cardiac damage following myocardial infarction (MI) causes excessive inflammation, which sustains tissue damage and often induces adverse cardiac remodeling toward cardiac function impairment and heart failure. Timely resolution of post-MI inflammation may prevent cardiac remodeling and development of heart failure. Cell therapy approaches for MI are time-consuming and costly, and have shown marginal efficacy in clinical trials. Here, nanoparticles targeting the immune system to attenuate excessive inflammation in infarcted myocardium are presented. Liposomal nanoparticles loaded with MI antigens and rapamycin (L-Ag/R) enable effective induction of tolerogenic dendritic cells presenting the antigens and subsequent induction of antigen-specific regulatory T cells (Tregs). Impressively, intradermal injection of L-Ag/R into acute MI mice attenuates inflammation in the myocardium by inducing Tregs and an inflammatory-to-reparative macrophage polarization, inhibits adverse cardiac remodeling, and improves cardiac function. Nanoparticle-mediated blocking of excessive inflammation in infarcted myocardium may be an effective intervention to prevent the development of post-MI heart failure.

Hypertension is the biggest contributing risk factor to cerebrovascular disease and is associated with increased risk of coronary artery disease. The May Measurement Month (MMM) campaign is a global initiative aimed at raising awareness of hypertension and acting as a temporary solution to the lack of screening programs worldwide. An opportunistic cross-sectional survey of participants aged ≥18 was carried out during May 2019 in Korea. Over 10â000 participants were recruited in the MMM campaign in Korea, with a slogan of 'A simple measure to save lives-#checkyourpressure'. A total of 9975 participants with valid clinical and blood pressure (BP) data were used for analysis. All participants were Korean in ethnicity, mean age was 57.2 (SD ± 21.2) years, 57.7% were females, and the mean body mass index was 23.4 kg/m2 (SD ± 3.3). In total, 37.7% of the participants reported a previous diagnosis of hypertension, and 91.3% of those diagnosed were on antihypertensive medications. For other comorbidities, 11.6% reported having diabetes mellitus, 2.0% had previous stroke, and 1.0% had previous myocardial infarction. Mean BP was 130.0/81.0 mmHg in the overall population. After multiple imputation, 47.6% of participants were classified as hypertensive (systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg or on treatment for raised BP). Among all hypertensive participants, the awareness rate, the treatment rate, and the control rate (systolic BP <140 mmHg and diastolic BP <90 mmHg) were 76.2%, 74.0%, and 50.5%, respectively. Of those on antihypertensive medication, the control rate was 68.2%. While awareness and treatment rates were relatively high in the MMM19 campaign, the BP control rate of the total hypertensive population was still only â¼50%, which demands more emphasis on strict BP control.
RESUMEN
In this study, we aimed to investigate the time course of new-onset complete atrioventricular block (CAVB) and its reversibility after transcatheter aortic valve implantation (TAVI). We analyzed 206 consecutive patients without baseline CAVB who underwent successful TAVI. The incidence of new-onset CAVB was determined to be 12.6% (26/206). Among these patients, 14 recovered from CAVB within 2 weeks (6.8%, 14/206), while the remaining 12 (5.8%, 12/206) underwent permanent pacemaker (PPM) insertion. Among the 12 patients who received the PPM, 4 were able to recover from CAVB within 4 months. Thus, only 8 among 206 patients (3.8%) showed persistent CAVB. Early-onset CAVB on the day of the procedure was the strongest predictor of PPM implantation (OR = 127). The electrocardiographic changes that occurred after TAVI were mostly recovered after 1 month. The most critical procedural factor that predicts CAVB and PPM insertion is the deep implantation (>4 mm) of a big valve (oversizing index >5.9%). In conclusion, the incidence of CAVB after TAVI was estimated to be at 12.6%. Two-thirds of these patients recovered from CAVB within 3 days, resulting in a final rate of persistent CAVB of 4%. To prevent CAVB, we have to implant an appropriate valve type with an optimal size and depth.

METHODS: Patients undergoing PCI to left anterior descending (LAD) bifurcation lesions with contemporary DES were analyzed from a nationwide registry. Baseline risk was assessed using the Age, Creatinine, and Ejection Fraction (ACEF) score. Target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, and target lesion revascularization, was assessed at 3 years. RESULTS: Among 1,089 patients with LAD bifurcation lesions, 548 (50.3%) patients underwent SB treatment. The SB treatment group showed a nonsignificant, but numerically lower rate of 3-year TLF (6.6% vs. 9.2%, HR 0.75, 95%CI 0.44-1.28, p = 0.29). In patients with low pretreatment risk (ACEF<1.22), SB treatment was associated with a lower rate of 3-year TLF (HR 0.43, 95%CI 0.19-0.96, p = 0.04), while no significant difference was observed in patients with high risk (ACEF≥1.22). The difference in the low risk group was mostly driven by target lesion revascularization (HR 0.24, 95%CI 0.08-0.75, p = 0.01). CONCLUSIONS: SB treatment for LAD bifurcation lesions showed favorable long-term outcomes compared with main-branch-only intervention, especially in patients with low pretreatment risk.

Background: The TALOS-AMI study highlighted the effectiveness of a de-escalation strategy shifting from ticagrelor to clopidogrel 1 month after percutaneous coronary intervention (PCI), resulting in significant reduction in clinical events, primarily attributed to a substantial decrease in bleeding events. Nevertheless, the impact of this strategy on outcomes based on sex remains unclear. Methods: This was a post-hoc analysis of the TALOS-AMI study. At 1 month after PCI, patients who remained adherent to aspirin and ticagrelor without experiencing major adverse events were randomized into either the de-escalation group (clopidogrel plus aspirin) or the active control group (ticagrelor plus aspirin) for an additional 12 months. The primary endpoint encompassed a composite of cardiovascular death, myocardial infarction, stroke, and Bleeding Academic Research Consortium bleeding type 2 or greater at 12 months after randomization. Results: Among the 2,697 patients included in this study, 454 (16.8%) were women. Women, characterized by older age and a higher prevalence of hypertension, diabetes, impaired renal function, and non-ST-segment myocardial infarction, exhibited a lower primary endpoint at 12 months compared to men [adjusted hazards ratio (HR), 0.60; 95% confidence interval (CI), 0.37-0.95; P = 0.03]. Compare to the active control group, the de-escalation group demonstrated a reduced risk of the primary endpoint in both women (adjusted HR, 0.38; 95% CI, 0.15-0.95; P = 0.039) and men (adjusted HR, 0.56; 95% CI, 0.40-0.79; P = 0.001) (interaction P = 0.46). Conclusions: In stabilized patients post-PCI with drug-eluting stents for acute myocardial infarction, the primary endpoint was lower among women compared to men. In this cohort, the benefits of an unguided de-escalation strategy from ticagrelor to clopidogrel were comparable in women and men.
RESUMEN
Ischemic heart disease remains the primary cause of morbidity and mortality worldwide. Despite significant advancements in pharmacological and revascularization techniques in the late 20th century, heart failure prevalence after myocardial infarction has gradually increased over the last 2 decades. After ischemic injury, pathological remodeling results in cardiomyocytes (CMs) loss and fibrosis, which leads to impaired heart function. Unfortunately, there are no clinical therapies to regenerate CMs to date, and the adult heart's limited turnover rate of CMs hinders its ability to self-regenerate. In this review, we present novel therapeutic strategies to regenerate injured myocardium, including (1) reconstruction of cardiac niche microenvironment, (2) recruitment of functional CMs by promoting their proliferation or differentiation, and (3) organizing 3-dimensional tissue construct beyond the CMs. Additionally, we highlight recent mechanistic insights that govern these strategies and identify current challenges in translating these approaches to human patients.
RESUMEN
The role of statins after endovascular abdominal aortic aneurysm repair (EVAR) has not been well established in an Asian context. In this study, the use of statins and their association with long-term health outcomes were evaluated in patients undergoing EVAR using the Korean National Health Insurance Service database. Among the 8893 patients who underwent EVAR from 2008 to 2018, 3386 (38.1%) were on statins prior to the procedure. Patients using statins had a higher prevalence of comorbidities, such as hypertension (88.4% vs. 71.5%), diabetes mellitus (24.5% vs. 14.1%), and heart failure (21.6% vs. 13.1%), compared with non-users (all p < 0.001). After propensity score matching, statin use prior to EVAR was associated with a lower risk of all-cause mortality (HR 0.85, 95% CI 0.78-0.92, p < 0.001) and cardiovascular mortality (HR 0.66, 95% CI 0.51-0.86, p = 0.002). Statin use following EVAR was associated with a lower risk of adverse events, but not significantly so. Patients on statins both preceding and following EVAR had a lower risk of all-cause mortality (HR 0.82, 95% CI 0.73-0.91, p < 0.001) and cardiovascular mortality (HR 0.62, 95% CI 0.44-0.87, p = 0.007), compared with statin non-users. Among Korean patients undergoing EVAR, the persistent use of statins prior to and after the procedure was associated with a lower risk of mortality, compared with non-statin users.
RESUMEN
Background: The use of a cardioverter defibrillator for the primary prevention of sudden cardiac death is not recommended within 40 days after acute myocardial infarction (AMI). We investigated the predictors for early cardiac death among patients who were admitted for AMI and successfully discharged. Methods: Consecutive patients with AMI were enrolled in a multicenter prospective registry. Among 10,719 patients with AMI, 554 patients with in-hospital death and 62 patients with early non-cardiac death were excluded. Early cardiac death was defined as a cardiac death within 90 days after index AMI. Results: Early cardiac death after discharge occurred in 168/10,103 (1.7%) patients. A defibrillator was not implanted in all patients with early cardiac death. Killip class ≥3, chronic kidney disease stage ≥4, severe anemia, cardiopulmonary support usage, no dual antiplatelet therapy at discharge, and left ventricular ejection fraction (LVEF) ≤35% were independent predictors for early cardiac death. The incidence of early cardiac death according to the number of factors added to LVEF criteria in each patient was 3.03% for 0 factor, 8.11% for 1 factor, and 9.16% for ≥2 factors. Each model that sequentially added the factors in the presence of LVEF criteria showed a significant gradual increase in predictive accuracy and an improvement in reclassification capability. A model with all factors showed C-index 0.742 [95% CI 0.702-0.781], p < 0.001; IDI 0.024 [95% CI 0.015-0.033], p < 0.001; and NRI 0.644 [95% CI 0.492-0.795], p < 0.001. Conclusion: We identified six predictors for early cardiac death after discharge from AMI. These predictors would help to discriminate high-risk patients over current LVEF criteria and to provide an individualized therapeutic approach in the subacute stage of AMI.
RESUMEN
BACKGROUND: Antithrombotic recommendations for relatively low risk patients with atrial fibrillation (AF) are not well established. Some patients with CHADS(2) score = 0 have a CHA(2) DS(2) -VASc score of 2, which indicated warfarin therapy in the latter system. We evaluated the thromboembolic risk in AF patients with a CHADS(2) score of 0 or 1. METHODS: A total of 695 patients with AF that were followed for ≥ 12 months (median 65.6 months, range 12-138 months), were analyzed retrospectively. The modified CHADS(2) score (MCS) was applied as follows. Each CHADS(2) score group was divided into 2 groups, A and B (i.e., MCS 0A vs 0B, and MCS 1A vs 1B) according to the number of nonmajor risk factors (female gender, chronic kidney disease, coronary artery disease, age 65-74 years). Group A had 0 or 1, and group B had 2 or more nonmajor risk factors. RESULTS: In patients with CHADS(2) score = 1, there were 13 thromboembolic events (0.65%/year) in 343 MCS 1A patients, and 12 thromboembolic events (1.90%/year) in 108 MCS 1B patients. Thromboembolic risk was significantly higher in the MCS 1B compared to the MCS 1A patients (P = 0.006). In 244 patients with CHADS(2) score = 0, the thromboembolic risk of MCS 0B was similar to that of MCS 0A (P = 0.095), and 26 patients had a CHA(2) DS(2) -VASc score of 2. CONCLUSION: Patients with MCS 1B had a higher thromboembolic risk than patients with MCS 1A. Antithrombotic strategies for patients with a CHA(2) DS(2) -VASc score of 2 but a CHADS(2) score of 0 need further investigation.

The performance and clinical implications of the deep learning aided algorithm using electrocardiogram of heart failure (HF) with reduced ejection fraction (DeepECG-HFrEF) were evaluated in patients with acute HF. The DeepECG-HFrEF algorithm was trained to identify left ventricular systolic dysfunction (LVSD), defined by an ejection fraction (EF) < 40%. Symptomatic HF patients admitted at Seoul National University Hospital between 2011 and 2014 were included. The performance of DeepECG-HFrEF was determined using the area under the receiver operating characteristic curve (AUC) values. The 5-year mortality according to DeepECG-HFrEF results was analyzed using the Kaplan-Meier method. A total of 690 patients contributing 18,449 ECGs were included with final 1291 ECGs eligible for the study (mean age 67.8 ± 14.4 years; men, 56%). HFrEF (+) identified an EF < 40% and HFrEF (-) identified EF ≥ 40%. The AUC value was 0.844 for identifying HFrEF among patients with acute symptomatic HF. Those classified as HFrEF (+) showed lower survival rates than HFrEF (-) (log-rank p < 0.001). The DeepECG-HFrEF algorithm can discriminate HFrEF in a real-world HF cohort with acceptable performance. HFrEF (+) was associated with higher mortality rates. The DeepECG-HFrEF algorithm may help in identification of LVSD and of patients at risk of worse survival in resource-limited settings.

BACKGROUND: Low-density lipoprotein-cholesterol (LDL-C) is used as a threshold and target for treating dyslipidemia. Although the Friedewald equation is widely used to estimate LDL-C, it has been known to be inaccurate in the case of high triglycerides (TG) or non-fasting states. We aimed to propose a novel method to estimate LDL-C using machine learning. METHODS: Using a large, single-center electronic health record database, we derived a ML algorithm to estimate LDL-C from standard lipid profiles. From 1,029,572 cases with both standard lipid profiles (total cholesterol, high-density lipoprotein-cholesterol, and TG) and direct LDL-C measurements, 823,657 tests were used to derive LDL-C estimation models. Patient characteristics such as sex, age, height, weight, and other laboratory values were additionally used to create separate data sets and algorithms. RESULTS: Machine learning with gradient boosting (LDL-CX) and neural network (LDL-CN) showed better correlation with directly measured LDL-C, compared with conventional methods (r = 0.9662, 0.9668, 0.9563, 0.9585; for LDL-CX, LDL-CN, Friedewald [LDL-CF], and Martin [LDL-CM] equations, respectively). The overall bias of LDL-CX (-0.27 mg/dL, 95% CI -0.30 to -0.23) and LDL-CN (-0.01 mg/dL, 95% CI -0.04-0.03) were significantly smaller compared with both LDL-CF (-3.80 mg/dL, 95% CI -3.80 to -3.60) or LDL-CM (-2.00 mg/dL, 95% CI -2.00 to -1.94), especially at high TG levels. CONCLUSIONS: Machine learning algorithms were superior in estimating LDL-C compared with the conventional Friedewald or the more contemporary Martin equations. Through external validation and modification, machine learning could be incorporated into electronic health records to substitute LDL-C estimation.

Periprocedural atrial fibrillation (AF) is associated with poor prognosis after transcatheter aortic valve replacement (TAVR). We evaluated the impact of long-term sinus rhythm (SR) maintenance on post-TAVR outcomes. We enrolled 278 patients treated with TAVR including 87 patients with periprocedural AF. Patients with periprocedural AF were classified into the AF-sinus rhythm maintained (AF-SRM) group or the sustained AF group according to long-term cardiac rhythm status after discharge. Patients without AF before or after TAVR were classified into the SR group. The primary clinical outcome was a composite of all-cause death, stroke, or heart failure rehospitalization. The AF-SRM and the SR groups showed significant improvements in left ventricular ejection fraction and left atrial volume index at one year after TAVR, while the sustained AF group did not. During 24.5 (±16.1) months of follow-up, the sustained AF group had a higher risk of the adverse clinical event compared with the AF-SRM group (hazard ratio (HR) 4.449, 95% confidence interval (CI) 1.614-12.270), while the AF-SRM group had a similar risk of the adverse clinical event compared with the SR group (HR 0.737, 95% CI 0.285-1.903). In conclusion, SR maintenance after TAVR was associated with enhanced echocardiographic improvement and favorable clinical outcomes.
RESUMEN
Background: We evaluated the effectiveness of extended dual antiplatelet therapy (DAPT) usage after 2nd-generation drug elution stent implantation in acute myocardial infarction (AMI) survivors with high ischemic risk characteristics who had no major bleeding for 24 months under at least 1 year of DAPT maintenance. Materials and methods: The primary ischemic and bleeding endpoints were the risk of mortality and the risk of BARC 3 or 5 (major) bleeding. We investigated the event rates for 2-5 years after the index procedure. Results: Of 3382 post-AMI survivors who met the PEGASUS-TIMI 54 (PEGASUS) criteria and without major bleeding until 2 years, 2281 (67.4%) maintained DAPT over 24 months, and 1101 (32.5%) switched DAPT to a single antiplatelet agent. The >24 M DAPT group showed a lower risk of mortality than the 12-24 M DAPT group (7.2 vs. 9.2%; adjusted hazard ratio: 0.648; 95% confidence interval: 0.595-0.976; p < 0.001). The mortality risk was significantly greater as the number of PEGASUS criteria increased (p < 0.001). DAPT > 24 months was not significantly associated with a decreased risk for major bleeding in the population meeting the PEGASUS criteria (2.0 vs. 1.1%; p = 0.093). The results were consistent after propensity-score matching and inverse probability weighting to adjust for baseline differences. Conclusion: Extended DAPT over 24 months was associated with a lower risk of mortality without increasing the risk of major bleeding among 2 years survivors after AMI who met the PEGASUS criteria and had no major bleeding events before 24 months.
RESUMEN
The current study aimed to investigate the association between serum UA levels and the mortality rate of AMI patients. We analyzed 5888 patients with successfully revascularized AMI (mean age: 64.0 ± 12.7 years). The subjects were divided into the high UA group (uric acid >6.5 mg/dL for males, >5.8 mg/dL for females) or the normal UA group based on initial serum UA level measured at admission. The primary outcome was all-cause mortality. A total of 4141 (70.3%) and 1747 (29.7%) patients were classified into the normal UA group and high UA groups, respectively. Over a median follow-up of 5.02 (3.07, 7.55) years, 929 (21.5%) and 532 (34.1%) patients died in each group. Cox regression analysis identified high UA levels as an independent predictor of all-cause mortality (unadjusted hazard ratio (HR) 1.69 [95% CI 1.52−1.88]; p < 0.001, adjusted HR 1.18 [95% CI: 1.05−1.32]; p = 0.005). The results were consistent after propensity-score matching and inverse probability weighting to adjust for baseline differences. The predictive accuracies of conventional clinical factor discrimination and reclassification were significantly improved upon the addition of hyperuricemia (C-index 0.788 [95% CI 0.775−0.801]; p = 0.005, IDI 0.004 [95% CI 0.002−0.006]; p < 0.001, NRI 0.263 [95% CI 0.208−0.318]; p < 0.001).
RESUMEN
This study aimed to investigate the relationship between a complex percutaneous coronary intervention (C-PCI) and long-term clinical outcomes in the AMI cohort. A total of 10,329 patients were categorized into the C-PCI and non-C-PCI groups. The primary ischemic endpoint was a composite of major adverse cardiac events (MACEs, cardiac death, myocardial infarction, stent thrombosis and revascularization). The primary bleeding endpoint was the risk of overt bleeding (BARC 2, 3 or 5). The median follow-up duration was 4.9 (2.97, 7.16) years. The risks of MACEs and bleeding were significantly higher in the C-PCI group (hazard ratio (HR): 1.72; 95% confidence interval (CI): 1.60 to 1.85; p < 0.001; and HR: 1.32; 95% CI: 1.17 to 1.50; p < 0.001, respectively). After propensity score matching, compared to the non-C-PCI group, the adjusted MACE rate in C-PCI remained significantly higher (p < 0.001), but no significant interaction (p = 0.273) was observed for bleeding. Significant differences in overt bleeding were observed only within the first three months (p = 0.024). The MACEs were consistently higher in the C-PCI group with or without severe comorbid conditions (p < 0.001 for both). Patients with AMI who undergo C-PCI experience worse long-term ischemic outcomes after successful PCI, regardless of the presence of severe comorbidities.
RESUMEN
This study aimed to investigate the efficacy of the HFA-PEFF score in predicting the long-term risks in patients with acute myocardial infarction (AMI) and an HFA-PEFF score ≥ 2. The subjects were divided according to their HFA-PEFF score into intermediate (2−3 points) and high (4−6 points) score groups. The primary outcome was all-cause mortality. Of 1018 patients with AMI and an HFA-PEFF score of ≥2, 712 (69.9%) and 306 (30.1%) were classified into the intermediate and high score groups, respectively. Over a median follow-up of 4.8 (3.2, 6.5) years, 114 (16.0%) and 87 (28.4%) patients died in each group. Multivariate Cox regression identified a high HFA-PEFF score as an independent predictor of all-cause mortality [hazard ratio (HR): 1.53, 95% CI: 1.15−2.04, p = 0.004]. The predictive accuracies for the discrimination and reclassification were significantly improved (C-index 0.750 [95% CI 0.712−0.789]; p = 0.049 and NRI 0.330 [95% CI 0.180−0.479]; p < 0.001) upon the addition of a high HFA-PEFF score to clinical risk factors. The model was better at predicting combined events of all-cause mortality and heart failure readmission (C-index 0.754 [95% CI 0.716−0.791]; p = 0.033, NRI 0.372 [95% CI 0.227−0.518]; p < 0.001). In the AMI cohort, the HFA-PEFF score can effectively predict the prognosis of patients with an HFA-PEFF score of ≥2.
RESUMEN
AIMS: Increased blood pressure (BP) and decreased heart rate (HR) are signs of stabilization in patients admitted for acute HF. Changes in BP and HR during admission and their correlation with outcomes were assessed in hospitalized patients with heart failure (HF) with reduced ejection fraction (HFrEF). METHODS: A novel modified reverse shock index (mRSI), defined as the ratio between changes in systolic BP and HR during admission, was devised, and its prognostic value in the early outcomes of acute HF was assessed using the Korean Acute HF registry. RESULTS: Among 2697 patients with HFrEF (mean age 65.8 ± 14.9 years, 60.6% males), patients with mRSI ≥1.25 at discharge were significantly younger and were more likely to have de novo HF. An mRSI ≥1.25 was associated with a significantly lower incidence of 60-day and 180-day all-cause mortality [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.31-0.77; HR 0.62, 95% CI 0.45-0.85, respectively], compared with 1 ≤ mRSI < 1.25 (all P < 0.001). Conversely, an mRSI <0.75 was associated with a significantly higher incidence of 60-day and 180-day all-cause mortality (adjusted HR 2.08, 95% CI 1.19-3.62; HR 2.24, 95% CI 1.53-3.27; all P < 0.001). The benefit associated with mRSI ≥1.25 was consistent in sub-group analyses. The correlation of mRSI and outcomes were also consistent regardless of admission SBP, presence of atrial fibrillation, or use of beta blockers at discharge. CONCLUSIONS: In patients hospitalized for HFrEF, the mRSI was a significant predictor of early outcomes. The mRSI could be used as a tool to assess patient status and guide physicians in treating patients with HFrEF.

Limited data exist on the temporal trend of major bleeding and its prediction by the Academic Research Consortium-High Bleeding Risk (ARC-HBR) criteria in acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI). We investigated 10-year trends of major bleeding and predictive ability of the ARC-HBR criteria in AMI patients. In a multicenter registry of 10,291 AMI patients undergoing PCI between 2004 and 2014 the incidence of Bleeding Academic Research Consortium (BARC) 3 and 5 bleeding was assessed, and, outcomes in ARC-defined HBR patients with AMI were compared with those in non-HBR. The primary outcome was BARC 3 and 5 bleeding at 1 year. Secondary outcomes included all-cause mortality and composite of cardiovascular death, myocardial infarction, or ischemic stroke. The annual incidence of BARC 3 and 5 bleeding in the AMI population has increased over the years (1.8% to 5.8%; p < 0.001). At 1 year, ARC-defined HBR (n = 3371, 32.8%) had significantly higher incidence of BARC 3 and 5 bleeding (9.8% vs. 2.9%; p < 0.001), all-cause mortality (22.8% vs. 4.3%; p < 0.001) and composite of ischemic events (22.6% vs. 5.8%; p < 0.001) compared to non-HBR. During the past decade, the incidence of major bleeding in the AMI population has increased. The ARC-HBR criteria provided reliable predictions for major bleeding, mortality, and ischemic events in AMI patients.
RESUMEN
BACKGROUND AND OBJECTIVES: Hypertension (HTN) is the most contributable risk factor for cardiovascular disease. May Measurement Month (MMM) is a global initiative to raise awareness of HTN and act as a temporary solution to the lack of screening programs worldwide. METHODS: An opportunistic cross-sectional survey of participants aged ≥18 was carried out in May 2019. Over 10,000 participants were recruited in the MMM 2019 Korea, with a slogan of "A simple measure to save lives - #checkyourpressure." RESULTS: A total of 9,950 participants with valid clinical blood pressure (BP) data were used for analysis. All participants were Korean in ethnicity. The mean age was 57.2±21.2 years, 57.8% were females, and the mean body mass index was 23.4±3.3 kg/m². Among the enrolled population, 20.1% were less than 30 years old, and 5.0% were 30-39 years old. 37.0% of the participants reported a previous diagnosis of HTN, and 91.3% of those diagnosed were on antihypertensive medications. Notably, more than 20% of the participants had not measured their BP during the last 12 months, and the awareness rate in the young hypertensive participants (aged <40) was less than 10%. Among hypertensive participants, the treatment rate was 69.3%, and the control rate among those taking medications was 61.2%. CONCLUSION: MMM 2019 Korea campaign reported high BP control rates in individuals with HTN, reaching 60%. However, the awareness rate in young hypertensive participants was less than 10% along with suboptimal management status. The MMM 2019 Korea again raised the importance of regular BP measurement in the younger population.
