RESUMO
There is currently an ongoing debate about the 'grey area' of heart failure with mid-range ejection fraction (HFmrEF). We evaluated characteristics, prognosis, and the effect of ß-blockers on clinical outcomes in patients with HFmrEF after acute myocardial infarction (AMI). We included a total of 10,785 patients and divided them into three groups: EF 40-49% (HFmrEF; n = 2717; reference); EF < 40% (reduced EF [HFrEF]; n = 1194); and EF ≥ 50% (preserved EF [HFpEF]; n = 6874). The primary outcome was 2-year all-cause mortality. HFmrEF was intermediate between HFrEF and HFpEF for baseline characteristics. The risk of all-cause mortality was lower for HFmrEF patients compared to HFrEF patients (adjusted hazard ratio [HR] 0.710; 95% confidence interval [CI] 0.544-0.927; P = 0.012). However, HFmrEF patients tended to be at higher risk for 2-year all-cause mortality than HFpEF patients (adjusted HR 1.235; 95% CI 0.989-1.511; P = 0.090). ß-blockers were associated with reductions in all-cause mortality for the entire cohort (adjusted HR 0.760; 95% CI 0.592-0.975; P = 0.031). ß-blockers were effective in patients with HFrEF (adjusted HR 0.667; 95% CI 0.471-0.944; P = 0.022), tended to be effective in patients with HFmrEF (adjusted HR 0.665; 95% CI 0.426-1.038; P = 0.072), but not effective in patients with HFpEF (adjusted HR 0.852; 95% CI 0.548-1.326; P = 0.478; interaction P = 0.026). In conclusion, clinical profiles and prognosis of patients with post-AMI HFmrEF are largely intermediate between HFrEF and HFpEF. ß-blockers reduced or tended to reduce 2-year all-cause mortality in patients with HFrEF or HFmrEF, respectively, but not those with HFpEF after AMI.

Left ventricular (LV) apical thrombus is a clinically important complication which can cause systemic embolization in patients with anterior acute myocardial infarction (AMI). Systolic dysfunction has been a risk factor for developing LV apical thrombus in AMI patients. However, the role of diastolic dysfunction in the development of LV apical thrombus in these patients is still unknown. We performed this study to evaluate whether diastolic dysfunction can influence the development of LV apical thrombus in anterior AMI patients. We retrospectively analyzed all consecutive anterior AMI patients with available echocardiographic images within 1 month from January 2005 to April 2016. After gathering clinical characteristics from their medical records, systolic and diastolic functions were analyzed from digitally stored echocardiographic images. We included a total of 1045 patients (748 males, mean age 64 ± 12 years) with anterior AMI, and 494 (47%) were diagnosed as STEMI. The incidence of LV apical thrombus was 3.3% (34/1045). The LV apical thrombus group had larger LV diastolic dimension, larger LV diastolic and systolic volumes, and lower LVEF than the no LV thrombus group. The LV apical thrombus group showed higher mitral E velocity over mitral annular E' velocity ratio, an indicator of LV end-diastolic pressure (P < 0.001). In the LV apical thrombus group, the incidence of grade 2 diastolic dysfunction (32 vs 12%, P = 0.001) and grade 3 diastolic dysfunction (26 vs 2%, P < 0.001) were significantly higher than in the no LV apical thrombus group. The presence of more than grade 2 diastolic dysfunction, LVEF and presence of LV apical aneurysm were statistically significant factors associated with LV apical thrombus after the multivariate analysis. In conclusion, along with LV systolic dysfunction and LV apical aneurysm, LV diastolic dysfunction was also related with the presence of LV apical thrombus in patients with anterior AMI.

BACKGROUND: Although brachial-ankle pulse wave velocity (baPWV) is well-known for predicting the cardiovascular mortality and morbidity, its anticipated value is not demonstrated well concerning acute stroke. METHODS: Total 1557 patients with acute stroke who performed baPWV were enrolled. We evaluated the prognostic value of baPWV predicting all-cause death and vascular death in patients with acute stroke Results: Highest quartile of baPWV was ≥23.64 m/s. All-caused deaths (including vascular death; 71) were 109 patients during follow-up periods (median 905 days). Multivariate Cox regression analysis revealed that patients with the highest quartile of baPWV had higher risk for vascular death when they are compared with patients with all other three quartiles of baPWV (Hazard ratio with 95% confidence interval [CI] 1.879 [1.022-3.456], p = .042 for vascular death). CONCLUSION: High baPWV was a strong prognostic value of vascular death in patients with acute stroke.

BACKGROUND AND OBJECTIVES: Concerns remain that early aspirin cessation may be associated with potential harm in subsets at high risk of ischemic events. This study aimed to assess the effects of P2Y12 inhibitor monotherapy after 3-month dual antiplatelet therapy (DAPT) vs. prolonged DAPT (12-month or longer) based on the ischemic risk stratification, the CHADS-P2A2RC, after percutaneous coronary intervention (PCI). METHODS: This was a sub-study of the SMART-CHOICE trial. The effect of the randomized antiplatelet strategies was assessed across 3 CHADS-P2A2RC risk score categories. The primary outcome was a major adverse cardiac and cerebral event (MACCE), a composite of all-cause death, myocardial infarction, or stroke. RESULTS: Up to 3 years, the high CHADS-P2A2RC risk score group had the highest incidence of MACCE (105 [12.1%], adjusted hazard ratio [HR], 2.927; 95% confidence interval [CI], 1.358-6.309; p=0.006) followed by moderate-risk (40 [1.4%], adjusted HR, 1.786; 95% CI, 0.868-3.674; p=0.115) and low-risk (9 [0.5%], reference). In secondary analyses, P2Y12 inhibitor monotherapy reduced the Bleeding Academic Research Consortium (BARC) types 2, 3, or 5 bleeding without increasing the risk of MACCE as compared with prolonged DAPT across the 3 CHADS-P2A2RC risk strata without significant interaction term (interaction p for MACCE=0.705 and interaction p for BARC types 2, 3, or 5 bleeding=0.055). CONCLUSIONS: The CHADS-P2A2RC risk score is valuable in discriminating high-ischemic-risk patients. Even in such patients with a high risk of ischemic events, P2Y12 inhibitor monotherapy was associated with a lower incidence of bleeding without increased risk of ischemic events compared with prolonged DAPT.

RESUMO
We sought to investigate the relation between worsening renal function (WRF) at 1-year follow-up and clinical outcomes at 3 years after acute myocardial infarction (AMI). We analyzed data from 13,104 patients enrolled in the national AMI registry from November 2011 to December 2015. Patients with all-cause death, recurrent myocardial infarction (re-MI), and rehospitalization for heart failure at 1-year follow-up after AMI were excluded. A total of 6,235 patients were extracted and divided into WRF and non-WRF groups. WRF was defined as a ≥25% decrease in estimated glomerular filtration rate (eGFR) from baseline to 1-year follow-up. The primary outcome was 3-year major adverse cardiac events, a composite of all-cause death, re-MI, and rehospitalization for heart failure. On average, a -1.5 ml/min/1.73 m2/y rate of decrease in eGFR was exhibited, and 575 patients (9.2%) exhibited WRF at 1-year follow-up. After multiple adjustments, WRF at 1-year follow-up was independently associated with increased risks of major adverse cardiac events (adjusted hazard ratio 1.498, 95% confidence interval 1.113 to 2.016, p = 0.01), all-cause death, and re-MI at 3-year follow-up. Older age, female, diabetes mellitus, hypertension, non-ST-segment elevation AMI, anterior AMI, anemia, left ventricular ejection fraction <35%, and baseline eGFR <30 ml/min/1.73 m2 were identified as independent predictors of WRF after AMI. In conclusion, WRF at 1-year follow-up after AMI intuitively seems like a risk marker indicating multiple co-morbidities. Monitoring serum creatinine in patients at 1-year follow-up after AMI may help to identify those who are at the highest risk and guide effective long-term therapeutics.

Gender difference studies in mortality after acute myocardial infarction (AMI) have shown inconsistent results. A total of 13,104 patients from the KAMIR-NIH between November 2011 and December 2015 were classified into young (n = 3837 [29.3%]) and elderly (n = 9267 [70.7%]) patients. For the study, women <65 and men <55 years of age were considered "young". In the adjusted model of the entire cohort, there was no significant difference in three-year all-cause mortality between women and men (17.8% vs. 10.3%; adjusted hazard ratio [HR], 0.953; 95% confidence interval [CI], 0.799-1.137). However, when the entire cohort was subdivided into two age groups, young women showed an 84.3% higher mortality rate than young men (adjusted HR, 1.843; 95% CI, 1.098-3.095). Contrariwise, elderly women patients had a 20.4% lower hazard of mortality compared with elderly men (adjusted HR, 0.796; 95% CI, 0.682-0.929). The interaction of gender with age was significant, even after multiple adjustments (adjusted p for interaction = 0.003). The purpose of this study was to assess whether gender differences depend on the patients' age. Based on our analysis, higher mortality of young women remains even in the contemporary era of AMI. A better understanding of the mechanisms underlying these differences is warranted.
RESUMO
AIM: To test the hypothesis that the impact of diabetes mellitus on clinical outcomes after acute myocardial infarction (AMI) can vary by age. METHODS: A total of 12,600 AMI patients from the Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) between November 2011 and December 2015 was classified into young (n = 3,590 [29%]) and old (n = 9,010 [72%]). Those less than 55 years of age were considered young. We performed comparisons of baseline characteristics, in-hospital treatments, and 3-year clinical outcomes between patients with and without diabetes after stratification according to age group. RESULTS: The prevalence of diabetes mellitus was 27% in the young AMI group. In the multivariable adjusted model of the entire cohort, diabetes mellitus was associated strongly with 3-year all-cause mortality (13% vs. 6.8%; adjusted hazard ratio [HR], 1.318; 95% confidence interval [CI], 1.138-1.526; P<0.001). When the entire cohort was subdivided into two age groups, young diabetic patients showed a 107% higher mortality rate than those without diabetes (adjusted HR, 2.07 [1.15-3.72];P = 0.015). Meanwhile, old diabetic patients had a 25% higher risk of mortality than non-diabetic patients (adjusted HR, 1.25 [1.08-1.46];P = 0.004). The interaction of diabetes with age was significant (adjusted P for interaction = 0.008). CONCLUSIONS: Diabetes mellitus is not uncommon in younger AMI patients, and the relative risk of 3-year mortality is significantly higher in young patients than in older counterparts. More aggressive treatments are needed to prevent future cardiovascular events in younger patients after AMI.

Although inodilators (dobutamine and milrinone) are widely used empirically for cardiogenic shock (CS), the efficacy of inodilators for patients with CS undergoing veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is controversial. We evaluated the effects of inodilators on clinical outcomes using the RESCUE (REtrospective and prospective observational Study to investigate Clinical oUtcomes and Efficacy of left ventricular assist device for Korean patients with cardiogenic shock; NCT02985008) registry. We selected and analyzed the clinical outcomes of 496 patients who underwent VA-ECMO and did or did not receive inodilators. Of the 496 patients, 257 (51.8%) died during hospitalization. We selected 191 matched pairs to adjust for baseline clinical characteristics after 1:1 propensity score matching (PSM). The univariate and multivariate analyses showed that the inodilator group had significantly lower in-hospital mortality than the no-inodilator group (unadjusted hazard ratio [HR], 0.768; 95% confidence interval [CI], 0.579-1.018; p = 0.066, adjusted HR, 0.702; 95% CI, 0.552-0.944; p = 0.019). For patients with CS undergoing VA-ECMO, inodilators may improve clinical outcomes.
RESUMO
AIMS: This study aimed to investigate differences in baseline and treatment characteristics, and in-hospital mortality according to the aetiologies of cardiogenic shock in patients undergoing veno-arterial-extracorporeal membrane oxygenation (VA-ECMO). METHODS AND RESULTS: The RESCUE registry is a multicentre, observational cohort that includes 1247 patients with cardiogenic shock from 12 centres. A total of 496 patients requiring VA-ECMO were finally selected, and the study population was stratified by cardiogenic shock aetiology [ischaemic cardiomyopathy (ICM, n = 342) and non-ICM (NICM, n = 154)]. The primary outcome of interest was in-hospital mortality. Sensitivity analyses including propensity-score matching adjustments were performed. Mean age of the entire population was 61.8 ± 14.2, and 30.8% were women. There were significant differences in baseline characteristics; notable differences included the older age of patients with ICM (65.1 ± 13.7 vs. 58.2 ± 13.8, P < 0.001), preponderance of males [258 (75.4%) vs. 85 (55.2%), P < 0.001], and higher prevalence of diabetes mellitus [140 (40.9%) vs. 39 (25.3%), P = 0.001] compared with patients in the NICM aetiology group. Patients with ischaemic cardiogenic shock were more likely to have longer shock duration before VA-ECMO implantation (518.7 ± 941.4 min vs. 292.4 ± 707.8 min, P = 0.003) and were less likely to undergo distal limb perfusion than those with NICM [108 (31.6%) vs. 79 (51.3%), P < 0.001]. In-hospital mortality in the overall cohort was 52.2%; patients with ICM had a higher unadjusted risk of in-hospital mortality [203 (59.4%) vs. 56 (36.4%); unadjusted hazard ratio, 2.295; 95% confidence interval, 1.698-3.100; P < 0.001]. There were no significant differences in the primary outcome between the two aetiologies following propensity-score matching multiple adjustments (adjusted hazard ratio, 1.265; 95% confidence interval, 0.840-1.906; P = 0.260). CONCLUSIONS: Results of the current study indicated among patients with cardiogenic shock undergoing VA-ECMO, ischaemic aetiology does not seem to impact in-hospital mortality. These findings underline that early initiation and appropriate treatment strategies of VA-ECMO for patients with ICM shock are required.

We evaluated whether thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) reduces adverse clinical outcomes within 30-days and 1-year periods. There is no well-designed, Korean data about the clinical impact of intracoronary TA during primary PCI in patients with ST-segment elevation myocardial infarction (STEMI). From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 3749 patients with STEMI undergoing primary PCI within 12 hours (60.8±12.9 years, 18.7% women) with pre-procedural Thrombolysis in Myocardial Infarction (TIMI) flow 0, 1 in coronary angiography were enrolled between November 2011 and December 2015. The patients were divided into two groups: PCI with TA (n=1630) and PCI alone (n=2119). The primary end-point was major adverse cardiac event (MACE), defined as the composite of cardiovascular death (CVD), recurrent MI and stroke for 30-days and 1-year. TA did not diminish the risk of MACE, all-cause mortality and CVD in all patients during 30-days or 1-year. After performing the propensity score matching, TA also did not reduce the risk of MACE (Hazard ratio (HR) with 95% Confidence Interval (CI):1.187 [0.863-1.633], p value=0.291), all-cause mortality (HR with 95% CI: 1.130 [0.776-1.647], p value=0.523) and CVD (HR with 95% CI: 1.222 [0.778-1.920], p value=0.384) during the 1-year period. In subgroup analysis, there was no benefit of clinical outcomes favoring PCI with TA. In conclusion, primary PCI with TA did not reduce MACE, all-cause mortality or CVD among the Korean patients with STEMI and pre-procedural TIMI flow 0, 1 during the 30-day and 1-year follow ups.
RESUMO
BACKGROUND AND OBJECTIVES: Although complete revascularization is known superior to incomplete revascularization in ST elevation myocardial infarction (STEMI) patients with multi-vessel coronary artery disease (MVCD), there are no definite instructions on the optimal timing of non-culprit lesions percutaneous coronary intervention (PCI). We compared 1-year clinical outcomes between 2 different complete multi-vessel revascularization strategies. METHODS: From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 606 patients with STEMI and MVCD who underwent complete revascularization were enrolled from November 2011 to December 2015. The patients were assigned to multi-vessel single-staged PCI (SS PCI) group (n=254) or multi-vessel multi-staged PCI (MS PCI) group (n=352). Propensity score matched 1-year clinical outcomes were compared between the groups. RESULTS: At one year, MS PCI showed a significantly lower rate of all-cause mortality (hazard ratio [HR], 0.42; 95% confidential interval [CI], 0.19-0.92; p=0.030) compared with SS PCI. In subgroup analysis, all-cause mortality increased in SS PCI with cardiogenic shock (HR, 4.60; 95% CI, 1.54-13.77; p=0.006), age ≥65 years (HR, 4.00; 95% CI, 1.67-9.58, p=0.002), Killip class III/IV (HR, 7.32; 95% CI, 1.68-31.87; p=0.008), and creatinine clearance ≤60 mL/min (HR, 2.81; 95% CI, 1.10-7.18; p=0.031). After propensity score-matching, MS PCI showed a significantly lower risk of major adverse cardiovascular event than SS PCI. CONCLUSIONS: SS PCI was associated with worse clinical outcomes compared with MS PCI. MS PCI for non-infarct-related artery could be a better option for patients with STEMI and MVCD, especially high-risk patients.
RESUMO
BACKGROUND AND OBJECTIVES: Aortic valve replacement (AVR) is the treatment of choice in severe symptomatic aortic stenosis (AS) patients. However, a substantial number of elderly patients refuse AVR and treated medically. We investigated their long-term prognosis. METHODS: From January 2005 to December 2016, we analyzed elderly patients with severe symptomatic AS who refused to have AVR. RESULTS: After screening of total 534 patients, we analyzed total 180 severe symptomatic AS patients (78±7 years old, 96 males). Hypertension was the most common cardiovascular risk factor (72%) and the most common symptom was dyspnea (66%). Calculated aortic stenosis area was 0.73±0.20 cm² and mean left ventricular ejection fraction (LVEF) was 57.8±12.2%. Total 102 patients died during follow-up period (39.1±31.0 months). One-, 3-, and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Of them, 87 died from cardiac causes, and 1-, 3-, and 5-year cardiac mortality rate was 18.0±2.9%, 38.2±3.8%, and 50.7±4.3%, respectively. Their all-cause mortality and cardiac mortality were significantly higher than those of controls. Univariate analysis showed that age, anemia, LVEF, and Log N-terminal pro B-type natriuretic peptide (NT-proBNP) were significant parameters in all-cause mortality (p<0.001, p=0.001, p=0.039, and p=0.047, respectively) and in cardiac mortality (p<0.001, p<0.001, p=0.046, and p=0.026, respectively). Multivariate analysis showed that age and anemia were significant prognostic factors for cardiac and all-cause mortality. CONCLUSIONS: In elderly severe symptomatic AS patients who treated medically, their 1-, 3- and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Age and anemia were significant prognostic factors for cardiac and all-cause mortality.
RESUMO
Although the new oral P2Y12 inhibitors, prasugrel/ticagrelor have shown greater efficacy than clopidogrel in patients with the acute coronary syndrome, but they have not shown better efficacy in Korean patients. So we evaluated the efficacy of the prasugrel/ticagrelor in patients with myocardial infarction (MI) and diabetes, a more high-risk patients group.From the Korea Acute Myocardial Infarction Registry-National Institute of Health, 3985 patients with MI and diabetes who underwent PCI were enrolled between November 2011 and December 2015. The patients were divided into 2 groups: clopidogrel (nâ=â2985) and prasugrel/ticagrelor (nâ=â1000).After propensity score matching, prasugrel/ticagrelor group showed a no significant difference in risk of the composite of cardiac death (CD), recurrent MI or stroke (hazard ratio [HR], 0.705; 95% confidence interval [CI], 0.474-1.048; Pâ=â.084). However, the risk of major bleeding was significantly higher in the prasugrel/ticagrelor group. (HR; 2.114, 95% CI; [1.027-4.353], Pâ=â.042). In subgroup analysis, major bleeding was significantly increased in the subgroup of creatinine clearance <60âml/min/1.73âm, hypertension, underwent a trans-femoral approach and diagnosed as NSTEMI among the prasugrel/ticagrelor group.The use of prasugrel/ticagrelor did not improve the composite of CD, recurrent MI or stroke, however, significantly increased major bleeding events in Korean patients with MI and diabetes undergoing PCI.

The anomalous origin of the right coronary artery (RCA) is a rare condition. Most RCA anomalies are usually found incidentally, but these findings have clinical significance because many patients, particularly young ones, present with sudden death, myocardial ischemia and syncope without other symptoms. We describe a case of a 39-year-old male patient that presented with effort chest pain and was diagnosed with anomalous RCA that originated from the ascending aorta with prior history of repairing ruptured sinus valsalva and ventricular septal defect. The anomalous origin of RCA was identified by multidetector computed tomography (MDCT). Successful percutaneous coronary intervention was performed guided by MDCT coronary images and intravascular ultrasound.
RESUMO
BACKGROUND AND OBJECTIVES: The comparison of long-term clinical effects between Sirolimus-eluting stent (SES) and Paclitaxel-eluting stents (PES) for treatment of acute myocardial infarction (AMI) remains unclear. Seeking to clarify this issue, we performed a retrospective analysis to evaluate four-year clinical outcomes of SES compared to PES treated AMI patients. SUBJECTS AND METHODS: From January 2004 to August 2006, all patients with acute ST-segment elevation myocardial infarction and acute non-ST segment elevation myocardial infarction who underwent percutaneous coronary intervention (PCI) by implantation of either SES or PES were enrolled. The occurrences of cardiac and non-cardiac deaths, recurrent infarction, target vessel revascularization (TVR) and stent thrombosis were analyzed. The composite end points of these major adverse cardiac events (MACE) were also analyzed. RESULTS: During the study period, a total of 668 AMI patients had visited, of which 522 patients (299 with SES and 223 with PES) were enrolled. During the four-year clinical follow-up, both groups showed similar occurrences of non-cardiac death (14.6±2.2% vs. 18.3±3.0%, p=0.26); cardiac death (6.8±1.52% vs. 11.2±2.6%, p=0.39); re-infarction (3.3±1.1% vs. 6.4±1.8%, p=0.31); and stent thrombosis (3.2±1.1% vs. 5.4±1.7%, p=0.53). However, occurrences of TVR {4.0±1.2% vs. 10.0±3.0%, hazard ratio (HR)=0.498, 95% confidence interval (CI)=0.257-0.967, p=0.039} and MACE (19.4±2.5% vs. 29.4±3.5%, HR=0.645, 95% CI=0.443-0.940, p=0.021) were significantly lower in the SES population. CONCLUSION: In AMI patients treated with either SES or PES implantation, the former had a significantly lower risk of TVR and MACE during four-year clinical follow-up. Rates of death, cardiac death or recurrent infarction, and stent thrombosis were similar.
RESUMO
Deep vein thrombosis (DVT) is a predisposing condition of pulmonary embolism which can be fatal. Usually, DVT is found in the lower extremities. However, DVT can be occurred in the upper extremities. The usual predisposing conditions of the upper extremity DVT include insertion of central venous catheters and pacemaker wires. Here, we report a case of upper extremity DVT after in vitro fertilization and embryo transfer. The patient was successfully controlled with subcutaneous administration of low molecular weight heparin.
