Objective. The pathophysiologic mechanism of how thyroid function is related to the development and prognosis of acute myocardial infarction (AMI) remains under explored, and there has been a lack of clinical investigations. In this study, we investigate the relationship between triiodothyronine (T3) level and cardiac ejection fraction (EF) as well as probrain natriuretic peptide (NT-proBNP) on admission and subsequent prognosis in AMI patients. Methods. We measured admission thyroid function, NT-proBNP, and EF by echocardiography in 345 patients diagnosed with AMI. Simple and multiregression analyses were performed to investigate the correlation between T3 level and EF as well as NT-proBNP. Major adverse cardiovascular events (MACE), including new-onset myocardial infarction, acute heart failure, and cardiac death, were documented during the follow-up. 248 participants were separated into three groups based on T3 and free triiodothyronine (FT3) levels for survival analysis during a 2-year follow-up. Results. 345 patients diagnosed with AMI were included in the initial observational analysis. 248 AMI patients were included in the follow-up survival analysis. The T3 levels were found to be significantly positively correlated with EF (R square=0.042, P<0.001) and negatively correlated with admission NT-proBNP levels (R square=0.059, P<0.001), which is the same with the correlation between FT3 and EF (R square=0.053, P<0.001) and admission NT-proBNP levels (R square=0.108, P<0.001). Kaplan-Meier survival analysis revealed no significant difference with regard to different T3 or FT3 levels at the end of follow-up. Conclusions. T3 and FT3 levels are moderately positively correlated with cardiac function on admission in AMI patients but did not predict a long-time survival rate. Further studies are needed to explain whether longer-term follow-up would further identify the prognosis effect of T3 on MACE and all-cause mortality.

Abstract Background：Drug-coated balloon (DCB) is a new technology that has emerged in recent years, and it has been proven to be effective and safe in the treatment of restenosis in the stent. The purpose of this article is to observe the safety and effectiveness of drug-coated balloons in patients with acute myocardial infarction. Methods: A total of 80 patients who were admitted to our department due to STEMI from January 2018 to December 2019 were selected. The subjects were randomly divided into drug-coated balloon treatment group (balloon group, n=38) and drug-eluting stent (DES) treatment group (stent group, n=42). The patients were followed up for 1 year to understand the incidence of major adverse cardiovascular events (MACEs) at 1 month, 6 months and 1 year after operation. Coronary angiography was reexamined at 1 year after operation to understand the late lumen loss (LLL) of the two groups. Results: At the 1-year follow-up, the target lesion LLL in the balloon group was (−0.12±0.46) mm, while the target lesion in the stent group was (0.14±0.37) mm (P<0.05). Within 1 year, the incidence of MACEs in the balloon group was 11%, and the incidence of MACEs in the stent group was 12%. There was no significant difference between the two groups. Conclusion: DCB therapy alone is safe and effective when PCI is performed for STEMI, and it shows good clinical results during the 1-year follow-up period.

Abstract Background Controversy exists regarding the use of beta-blockers (BBs) among patients with acute myocardial infarction (AMI) in contemporary reperfusion era. Previous studies predominantly focused on beta-blockers prescribed at discharge, and the effect of long-term adherence to beta-blocker on major adverse cardiovascular events (MACE) remains unclear. Objective To explore the association between long-term beta-blocker use patterns and MACE among contemporary AMI patients. Methods We enrolled 7860 patients with AMI, who were discharged alive and prescribed with BBs based on CAMI registry from January 2013 to September 2014. Patients were divided into two groups according to BBs use pattern: Always users group (n=4476) were defined as patients reporting BBs use at both 6- and 12-month follow-up; Inconsistent users group were defined as patients reporting at least once not using BBs at 6- or 12-month follow-up. Primary outcome was defined as MACE at 24-month follow-up, including all-cause death, non-fatal MI and repeat-revascularization. Multivariable cox proportional hazards regression model was used to assess the association between BBs and MACE. Results Baseline characteristics are shown in table 1. At 2-year follow-up, 518 patients in inconsistent users group (15.6%) and 548 patients in always users group (12.3%) had MACE. After multivariable adjustment, inconsistent use of BBs was associated with higher risk of MACE (HR: 1.323, 95% CI: 1.171–1.493, p<0.001). Table 1 Baseline characteristics Variable Always user (N=4476) Inconsistent user (N=3384) P value Age (years) 60.6±12.0 61.2±12.2 <0.001 Male 3381 (75.7%) 2461 (74.3%) 0.084 Diabetes 892 (20.0%) 610 (18.4%) 0.003 Hypertension 2372 (53.2%) 1543 (46.6%) <0.001 Dyslipidemia 244 (5.5%) 126 (3.8%) <0.001 Prior myocardial infarction 351 (7.9%) 232 (7.0%) <0.001 Heart failure 88 (2.0%) 63 (1.9%) <0.001 Chronic obstructive pulmonary disease 66 (1.5%) 60 (1.8%) <0.001 Current smoker 2054 (46.1%) 1579 (47.8%) 0.179 Left ventricular ejection fraction (%) 53.7±11.48 54.0±10.9 <0.001 Major Adverse Cardiovascular Events 548 (12.3%) 518 (15.6%) <0.001 Conclusions Our results showed consistent BBs use was associated with reduced risk of MACE among patients with AMI managed by contemporary treatment.

Several studies have shown that both chronic kidney disease (CKD) and diabetes mellitus are risk factors for mortality in patients with acute myocardial infarction (AMI). This study was undertaken to investigate influence of CKD on the prognostic significance of diabetes in patients with AMI. Between January 1996 and December 2005, 888 patients with AMI underwent coronary angiography within 24 hours after the onset of chest pain. CKD was difined estimated glomerular filtration rate (eGFR) of less than 60.0 ml/minute/1.73 m 2 of body-surface area (stage3–5). Kaplan-Meier method was used to compare 5-year survival of diabetic and non-diabetic patients, in the presence (n=337) or absence (n=551). Kaplan-Meier curves for 5-year survival rate are shown in Figure . In the absence of CKD, there was no significant difference in 5-year survival rate between patients with diabetes and those without (93 % v.s. 94 %, p=0.82). In patients with CKD, however, diabetes was associated with lower 5-year survival rate (65 % v.s. 87 %, p<0.001). Multivariate analysis showed that diabetes was an independent predictor for 5-year survival in patients with CKD (OR 3.2, 95%CI 1.8–5.8, p=0.0002), but not in patients without CKD (OR 1.1, 95%CI 0.4–2.5, p=0.82). Diabetes mellitus was an independent predictor for death after AMI in patients with CKD. Aggressive treatment after AMI should be advocated in diabetic patients with CKD.

Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

Abstract Introduction Several studies have addressed the importance of transthoracic echocardiography (TTE) in risk prediction of subsequent adverse events after ST elevation myocardial infarction (STEMI). While several traditional echo parameters have a well-established prognostic value, data derived from 2D-Speckle Tracking Echocardiography (2DSTE) needs further investigation. Objectives To determine if 2DSTE parameters provide additional information beyond conventional echocardiography to predict long-term adverse outcomes in patients admitted with STEMI Methods Retrospective, single-center study, that included all patients without previous cardiovascular events admitted with STEMI (who underwent primary coronary angioplasty) between 2015 and 2017. Patients with poor acoustic windows, severe valvular disease, irregular heart rhythm, and those who died during hospital stay were excluded. We reviewed all pre-discharge TTE to assess conventional parameters of LV systolic and diastolic function and data obtained by 2DSTE: global longitudinal strain (GLS) and peak strain dispersion (PSD), an index that is the standard deviation from time to peak strain of all segments over the entire cardiac cycle. Demographic and clinical data was obtained through electronic hospital records. Minimum follow-up was 2 years. The primary endpoint was a composite of all-cause mortality and cardiovascular re-admission at follow-up. Survival analysis was used to determine independent predictors of the primary endpoint. Results 377 patients were included, mean age 62±13 years, 72% male. Mean LVEF was 50±10% with 19% of patients having LVEF &lt;40%. Mean indexed left atrium volume (LAVi) was 33±10 ml/m2, mean GLS was −14±4%, and PSD was 60±22 msec. Average follow-up was 36±11 months, with a combined endpoint of mortality and hospitalization of 27% (n=102) Univariate analysis of echocardiographic variables revealed an association between heart rate, LVEF, indexed LV end-systolic volume, indexed stroke volume, LAVi, GLS and PSD with the endpoint. However, on multivariate analysis only LAVi [HR 1.030 (95% CI 1.009 - 1.051), p-value = 0.005] and PSD [HR 1.011 (95% CI 1.002 - 1.020), p-value = 0.012] remained independent predictors of the primary endpoint. We determined that a PSD value higher than 52 msec has a sensitivity of 76% and a negative predictive value of 83% for mortality and hospitalization, and that this cut-off point discriminates patients at a higher risk of events in Kaplan-Meier Survival analysis with a Log-Rank p-value=0.001. Conclusion PSD derived by longitudinal strain analysis is a promising prognostic predictor after STEMI. PSD outperformed conventional echocardiographic parameters in the risk stratification of STEMI patients at discharge.

Introduction. miRNAs contribute to a variety of essential biological processes including development, proliferation, differentiation, and apoptosis. Circulating microRNAs are very stable and have shown potential as biomarkers of cardiovascular disease. microRNA-208b expression was increased in the blood of patients with acute myocardial infarction (AMI) and has been proposed as a biomarker for early diagnosis. In this pilot study, we investigate the potential of circulating miR-208b as a prognostic biomarker of 6-month survival in AMI patients. Methods. Plasma samples from 21 patients and 8 age- and gender-matched healthy adults were collected, and circulating levels of miR-208b were detected using quantitative real-time PCR. Results. miR-208b levels were higher in healthy control subjects (9.6-fold; P≤0.05). Within the AMI patients, the levels of miR-208b were significantly lower in the survivor versus nonsurvivor group (fold change = 6.51 and 14.1, resp.; P≤0.05). The Kaplan-Meier curve revealed that the 6-month survival time was significantly higher among AMI patients with a relative expression of miR-208b lower than 12.38. The hazard ratio (HR) for the relative expression of miR-208b (<12.38 was the reference) was 5.08 (95% CI: 1.13–22.82; P=0.03). Conclusion. Our results showed that elevated miR-208b expression was associated with reduced long-term survival in AMI patients. These pilot data indicate the need for a large follow-up study to confirm whether miR-208b can be used as a predictor of 6-month survival time after AMI.

Subclinical hypothyroidism (SCH) is a common condition that is often observed without therapy. However, no evidence-based recommendation exists with regards to how patients with untreated SCH should be monitored.Monitoring involves regular assessment of symptoms and signs of hypothyroidism (HYPO) and biochemical tests of thyroid function. An important question when repeated tests of thyroid function are performed is how large a difference in test results is needed to be confident that the change is real and not just due to chance variation.Recent data show that the least significant difference between two tests in SCH is 40% for TSH and 15% for free thyroxine and free triiodothyronine, with 90% confidence. Furthermore, monitoring has to be based on biochemical function testing because serial evaluation of symptoms and signs related to HYPO is rather insensitive in detecting worsening of thyroid insufficiency.When the presence of thyroid peroxidase auto-antibodies (TPO-Ab) in serum has been demonstrated, repeated measurements do not add much useful information in the monitoring of individual subclinical hypothyroid patients, as levels of TPO-Ab vary in parallel with TSH in these patients.Lastly, we discuss how differences in the monitoring procedure influence the diagnostic outcome, and we suggest a follow-up approach for untreated subclinical hypothyroid patients.

Background: Long-term effects of cardiac autologous cell therapy are not well known. We performed a 3 year follow-up of the ASTAMI study. Patients with acute ST-elevation anterior wall myocardial infarctions were initially randomized to either intracoronary injection of autologous mononuclear bone marrow cells (mBMCs) (n=50) or control (n=50). At 6 months, LV ejection fraction improved in both groups, with no significant difference between groups. Methods: All eligible patients underwent MRI with a 1,5 T scanner (Siemens) 2–3 weeks, 6 months and mean(SD) 3,2 (0,2) years after myocardial infarction and stem cell injection. Infarct size was determined from gadolinium late-enhancement MR images. All images were analyzed by experienced observers blinded for treatment assignment. Left ventricular volumes were calculated by the area-length method. Results: There was no significant difference in EDV, ESV or LVEF between baseline and 3 years in neither group. Infarction volume was reduced at 3 years in both groups (p<0,001). No significant effects of mBMC treatment could be identified on LV volumes, LVEF or infarct size. Thus intracoronary injection of mBMCs in acute myocardial infarction does not improve global LV function over a 3 year follow-up. Left ventricular function after mBMC-treatment

AbstractThis study investigated the outcomes and major adverse cardiovascular events (MACEs) incurred by acute myocardial infarction (AMI) patients comorbiding with hypertension and hyperhomocysteinemia (HHcy) during hospitalization and 1-year follow-up. 648 consecutive AMI patients were divided into four categories: (1) hypertension with Hcy ≥ 15 µmol/L; (2) hypertension with Hcy < 15 µmol/L; (3) no-hypertension with Hcy ≥ 15 µmol/L; (4) no-hypertension with Hcy < 15 µmol/L. Information taken from these case files included gender, past medical history, vital signs, laboratory examination, electrocardiogram, coronary angiography, cardiac ultrasound, and medicine treatment. The primary endpoints were duration of coronary care units (CCU) stay, duration of in-hospital stay, and MACEs during follow-up. Our data show that hypertension and HHcy have a synergistic effect in AMI patients, AMI comorbiding with hypertension and HHcy patients had more severe multi-coronary artery disease and more frequent non-culprit coronary lesions complete clogging, had a higher prevalence of pro-brain natriuretic peptide, and significant decreases in the left ventricular ejection fraction. These patients had significant increases in the duration of CCU stay and in-hospital stay, had significant increase in the rate of MACEs, had significant decreases in the survival rate during follow-up.
