Abstract
OBJECTIVES In line with the cardiac fast track, the 'green pathway for patients with heart attack' policy in China is implemented to reduce door-to-balloon time in patients with ST-segment elevation myocardial infarction (STEMI). However, the difference in prehospital delay between urban and rural areas of China and its impact on prognosis is unclear. DESIGN Prospective observational study. SETTING This study was conducted in a tertiary hospital, the only nationally accredited chest pain centre with percutaneous coronary intervention (PCI) capacity in Pizhou, China. PARTICIPANTS 394 patients with STEMI without patients with in-hospital STEMI or patients lost to follow-up were included. PRIMARY OUTCOME MEASURES Primary outcome was major adverse cardiovascular events (MACEs), including cardiac death, non-fatal myocardial infarction and heart failure. RESULTS Among 394 patients enrolled, 261 (66.2%) were men, the median age was 69 years (interquartile range: 61-77 years), and 269 (68.3%) were from rural areas. Symptom-to-door (S2D) time was significantly longer for rural patients than for urban patients (p<0.001). Cox regression analyses revealed living in rural areas was independently associated with prolonged S2D time (adjusted HR 0.59; 95% CI 0.43 to 0.81; p=0.001). HR of <1 indicates that the S2D time is longer for patients in the rural group (group of interest). During 1-year follow-up, the incidence of MACEs was higher in rural patients (p=0.008). The unadjusted OR for MACEs between rural and urban patients was 2.22 (95% CI 1.22 to 4.01). Adjusting for sex did not attenuate the association (OR 2.06; 95% CI 1.13 to 3.76), but after further adjusting for age, cardiac function classification, S2D time and performance of primary PCI, we found that odds were similar for rural and urban patients (OR 1.19; 95% CI 0.59 to 2.38). CONCLUSIONS Rural patients with STEMI had a longer S2D time, which led to a higher incidence of MACEs. This study provides rationales for taking all the measures to avoid prehospital delay.

Palliative Care Use in Patients With Acute Myocardial Infarction and Do-Not-Resuscitate Status From a Nationwide Inpatient Cohort. Mayo Clin Proc 2022; 98:569-578. [PMID: 36372598 DOI: 10.1016/j.mayocp.2022.08.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 08/17/2022] [Accepted: 08/23/2022] [Indexed: 11/12/2022]
Abstract
OBJECTIVE To examine the predictors, treatments, and outcomes of the use of palliative care in patients hospitalized with acute myocardial infarction (AMI) who had a do-not-resuscitate (DNR) order. PATIENTS AND METHODS Using the National (Nationwide) Inpatient Sampling database for 2015-2018, we examined the predictors, in-hospital procedures, and outcomes of palliative care recipients among patients with AMI who had a DNR order. RESULTS We identified 339,270 admissions with AMI that had a DNR order, including patients who received palliative care (n=113,215 [33.4%]). Compared with patients who did not receive palliative care, these patients were more frequently younger (median age, 81 vs 83 years; P<.001), were less likely to be female (50.9% [57,626 of 113,215] vs 54.7% [123,652 of 226,055]; P<.001), and were more likely to present with cardiac arrest (11.6% [13,133 of 113,215] vs 6.9% [15,598 of 226,055]; P<.001). Patients were more likely to receive palliative care at a large (odds ratio [OR], 1.47; 95% CI, 1.44 to 1.50) or teaching (OR, 2.10; 95% CI, 2.04 to 2.16) hospitals compared with small or rural ones. Patients receiving palliative care were less likely to be treated invasively, with reduced rates of invasive coronary angiography (OR, 0.46; 95% CI, 0.45 to 0.47) and percutaneous coronary intervention (OR, 0.47; 95% CI, 0.45 to 0.48), and were more likely to die in the hospital (52.4% [59,325 of 113,215] vs 22.9% [51,766 of 226,055]). CONCLUSION In patients who had a DNR status and were hospitalized and received a diagnosis of AMI, only one-third received palliative care.

Abstract
BACKGROUND Rapidly progressive, extensive myocardial injury/infarction (RPEMI) beyond the concept of wave-front phenomenon can be observed even when achieving timely reperfusion; however, the pathogenesis of RPEMI remains unknown. This retrospective study investigated clinical and lesion characteristics of RPEMI, focusing on culprit-lesion morphology (CLM). METHODS Among patients with extensive anterior-wall ST-segment elevation myocardial infarction due to proximal left anterior descending artery lesions who had reperfusion within 3 hours of symptom onset, 60 patients undergoing both intravascular ultrasound and cardiac magnetic resonance imaging were enrolled. Myocardial injury/infarction before reperfusion therapy was assessed by QRS scores at hospitalization electrocardiogram, and the extent of myocardial injury/infarction was evaluated by cardiac magnetic resonance imaging, which measured area at risk, infarct size, myocardial salvage index, microvascular obstruction, and left ventricular ejection fraction. RPEMI was defined as lower left ventricular ejection fraction (less median value) with microvascular obstruction. RESULTS Despite comparable onset-to-door and onset-to-reperfusion times and area at risk, patients with RPEMI showed higher QRS scores at hospitalization (5 [4.3-6] versus 3 [2-4], P<0.001) and infarct size (26.5±9.1 versus 20.4±10.5%, P=0.04), and a tendency toward lower myocardial salvage index (0.27±0.14 versus 0.36±0.20, P=0.10) compared with those without. Patients with versus without RPEMI more frequently observed specific CLM on intravascular ultrasound, characterized by the combination of vulnerable plaques, plaque ruptures, and/or large thrombi. When stratified by CLM-score composed of these 3 criteria, higher CLM-scores were or tended to be associated with higher QRS scores and incidence of RPEMI. In multivariate analyses including no-reflow phenomenon and final coronary-flow deterioration, increased CLM-score (≥2) was independently associated with high QRS scores and RPEMI (odd ratio 11.25 [95% CI, 2.43-52.00]; P=0.002). CONCLUSIONS Vulnerable CLM was a consistent determinant of advanced myocardial injury/infarction both before and after reperfusion therapy and may play a pivotal role in the development of RPEMI.

Abstract
BACKGROUND When patients with type A acute aortic dissection (TAAAD) present with changes to their ST-segment, diagnostic and treatment delays increase significantly. The performance of transthoracic echocardiography (TTE) screening of TAAAD in patients with ST-segment elevated myocardial infarction (STEMI) is yet to be validated. METHODS The diagnostic performance of TTE alone and combined with the aortic dissection risk score (ADRS) in TAAAD was evaluated. In this retrospective study (ChiCTR, No. 2000031291), TTE was reviewed to detect direct/indirect signs of TAAAD. The ADRS of each patient was calculated according to guidelines. Case adjudication was based on advanced imaging and surgery. RESULTS Among a total of 442 patients, TAAAD was diagnosed in 146 (33.0%). The presence of direct TTE signs had a sensitivity of 43.0% [95% confidence interval (CI): 35.0% to 52.0%] and specificity of 97.0% (95% CI: 95.0% to 99.0%), and the presence of any TTE sign had a sensitivity of 97.0% (95% CI: 93.0% to 99.0%) and specificity of 78.0% (95% CI: 73.0% to 82.0%) for TAAAD. The additive value of TTE was most evident in patients with low clinical probability for TAAAD (ADRS ≤1). The presence of ADRS ≤1 plus an absence of direct TTE signs for TAAAD rule-out had a sensitivity of 98.4% (95% CI: 96.1% to 99.6%). CONCLUSIONS The use of TTE adds value in the screening of TAAAD in STEMI patients. In patients with low clinical probability for TAAAD, direct TTE signs can be used to rapidly identify those who require advanced imaging.

Abstract
Background Using contemporary data from NORIC (Norwegian Registry of Invasive Cardiology) we investigated the predictive value of patient age and time from ECG diagnosis to sheath insertion (ECG‐2‐sheath) in primary percutaneous coronary intervention for ST‐segment–elevation myocardial infarction (STEMI). Methods and Results Data from 11 226 patients collected from all centers offering 24/7/365 primary percutaneous coronary intervention service were explored. For patients aged <80 years the mortality rates were 5.6% and 7.6% at 30 days and 1 year, respectively. For octogenarians the corresponding rates were 15.0% and 24.2%. The Cox hazard ratio was 2.02 (1.93–2.11, P value <0.0001) per 10 years of patient age. Time from ECG‐2‐sheath was significantly associated with mortality with a 3.6% increase per 30 minutes of time. Using achievement of time goal <90 minutes in patients aged >80 years and mortality at 30 days, mortality was 10.5% and 17.7% for <90 or ≥90 minutes, respectively. The number needed to prevent 1 death was 39 in the whole population and 14 in the elderly. Restricted mean survival gains during median 938 days of follow‐up in patients with ECG‐2‐sheath time <90 minutes were 24 and 76 days for patients aged <80 and ≥80 years, respectively. Conclusions Time from ECG‐diagnosis to sheath insertion is strongly correlated with mortality. This applies especially to octogenarians who derive the most in terms of absolute mortality reduction.

Abstract
Emerging evidence suggests that 7-ketocholesterol (7-KC), one of the most abundant dietary oxysterols, causes inflammation and cardiovascular diseases. Here we show the deteriorating effects of dietary 7-KC on myocardial ischemia-reperfusion (IR) injury and detailed the molecular mechanisms. A high-fat high-cholesterol diet containing 7-KC (7KWD) for 3 weeks increased the plasma 7-KC level compared with high-fat high-cholesterol diet in mice. In wild-type mice but not in CCR2-/- mice, dietary 7-KC increased the myocardial infarct size after IR. Flow cytometry revealed that the ratio of Ly-6Chigh inflammatory monocytes to total monocytes was increased in the 7KWD group. Unbiased RNA sequencing using murine primary macrophages revealed that 7-KC regulated the expression of transcripts related to inflammation and cholesterol biosynthesis. We further validated that in vitro, 7-KC induced endoplasmic reticulum stress, mitochondrial reactive oxygen species production, and nuclear factor-kappa B activation, which are associated with increased mRNA levels of proinflammatory cytokines. Administration of N-acetyl-L-cysteine or siRNA-mediated knockdown of PKR-like endoplasmic reticulum kinase or endoplasmic reticulum oxidase 1α suppressed the levels of 7-KC-induced inflammation. Dietary 7-KC exacerbates myocardial IR injury through monocyte/macrophage-mediated inflammation. Endoplasmic reticulum stress and oxidative stress are involved in the 7-KC-induced proinflammatory response in macrophages.

Implementation of a Night Service of Helicopter Transportation to Reduce the Time to Revascularization in STEMI Patients in a Mountainous Region: Impact on Outcomes. J Clin Med 2022; 11:jcm11175089. [PMID: 36079018 PMCID: PMC9457436 DOI: 10.3390/jcm11175089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 08/25/2022] [Accepted: 08/28/2022] [Indexed: 11/29/2022] Open
Abstract
Background: Treatment delays are the most easily audited index of quality of care in the setting of ST-segment elevation myocardial infarction; among the components of ischemia time, system delay has been demonstrated to be a predictor of outcomes, and in a mountainous region it relies mostly upon helicopter rescue service. Aim: The aim of the study is to analyze the impact of the activation of helicopter rescue service for the nighttime for urgent transportation of patients on the time to revascularization and on the outcomes of STEMI patients. Methods: Data were prospectively collected in a database and retrospectively split into two different cohorts, based on the presentation date in the 18 months before, or after, the first day of implementation of the new organizational model. The patients were also split into two groups based on the place of STEMI diagnosis, either the chief town territory or the rest of the region, and retrospectively evaluated for vital status at 30 days and 2 years after index event. Results: The number of patients included was 751. For patients coming from outside Trento, an improvement in ST-segment resolution was shown (ST-segment elevation reduction >50% in 54.0% of the patients vs. 36.4%, p < 0.01). Moreover, a reduction in diagnosis-to-reperfusion median time has been demonstrated (from 105 to 97 min, p < 0.01), mainly driven by a reduction during the night shift (from 119 to 100 min, p = 0.02). With regard to 30-day and 2-year mortality, no statistically significant differences were achieved. Discussion: The organizational effort has translated into a significant reduction in the treatment delay for patients coming from outside the chief town. However, although a longer diagnosis to reperfusion time has been related to a higher mortality, a significant reduction in mortality was not demonstrated in our study. However, an improvement in ST-segment elevation resolution was shown for patients coming from outside the city of Trento, a result that could have other potential clinical benefits. Conclusions: Implementation of night flight proved to be effective in reducing the time between the diagnosis and the treatment of patients in the setting of STEMI, improving ST-segment elevation resolution, although no impact was shown on short- and long-term mortality.

Abstract
The novel coronavirus of 2019 (COVID-19) has resulted in a global pandemic; COVID-19 has resulted in significant challenges in the delivery of healthcare, including emergency management of multiple diagnoses, such as stroke and ST-segment myocardial infarction (STEMI). The aim of this study was to identify the impacts of the COVID-19 pandemic on emergency department care of stroke and STEMI patients. In this study a review of the available literature was performed using pre-defined search terms, inclusion criteria, and exclusion criteria. Our analysis, using a narrative review format, indicates that there was not a significant change in time required for key interventions for stroke and STEMI emergent management, including imaging (door-to-CT), tPA administration (door-to-needle), angiographic reperfusion (door-to-puncture), and percutaneous coronary intervention (door-to-balloon). Potential future areas of investigation include how emergency department (ED) stroke and STEMI care has adapted in response to different COVID-19 variants and stages of the pandemic, as well as identifying strategies used by EDs that were successful in providing effective emergency care in the face of the pandemic.

Clinical Outcomes in Pre-Hospital Activation and Direct Cardiac Catheterisation Laboratory Transfer of STEMI for Primary PCI. Heart Lung Circ 2022; 31:974-984. [PMID: 35227611 DOI: 10.1016/j.hlc.2022.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 12/05/2021] [Accepted: 01/13/2022] [Indexed: 10/19/2022]
Abstract
INTRODUCTION Pre-hospital activation and direct cardiac catheterisation laboratory (CCL) transfer of ST segment elevation myocardial infarction (STEMI) has previously been shown to improve door-to-balloon (DTB) times yet there is limited outcome data in the Australian context. We aimed to assess the impact of pre-hospital activation on STEMI performance measures and mortality. METHODS Prospective cohort study of consecutive ambulance transported STEMI patients treated with primary percutaneous coronary intervention (PCI) patients over a 10-year period (1 January 2008-31 December 2017) at The Prince Charles Hospital, a large quaternary referral centre in Brisbane, Queensland Australia. Comparisons were performed between patients who underwent pre-hospital CCL activation and patients who did not. STEMI performance measures, 30-day and 1-year mortality were examined. RESULTS Amongst 1,009 patients included (mean age: 62.8 yrs±12.6), pre-hospital activation increased over time (26.6% in 2008 to 75.0% in 2017, p<0.001). Median DTB time (35 mins vs 76 mins p<0.001) and percentage meeting targets (DTB<60 mins 92% vs 27%, p<0.001) improved significantly with pre-hospital activation. Pre-hospital activation was associated with significantly lower 30-day (1.0% vs 3.5%, p=0.007) and 1-year (1.2% vs 7.7%, p<0.001) mortality. After adjusting for confounders and mediators, we observed a strong total effect of pre-hospital activation on 1-year mortality (OR 5.3, 95%CI 2.2-12.4, p<0.001) compared to patients who did not have pre-hospital activation. False positive rates were 3.7% with pre-hospital activation. CONCLUSION In patients who underwent primary PCI for STEMI, pre-hospital activation and direct CCL transfer is associated with low false positive rates, significantly reduced time to reperfusion and lower 30-day and 1-year mortality.

Abstract
Despite the presence of clinical guidelines recommending that β-blocker treatment be initiated early after reperfused myocardial infarction (RMI), acute myocardial infarction remains a leading cause of chronic heart failure (CHF). In this study, we compared the effects of donepezil, metoprolol, and their combination on the progression of cardiac remodeling in rats with RMI. The animals were randomly assigned to untreated (UT), donepezil-treated (DT), metoprolol-treated (MT), and a combination of donepezil and metoprolol (DMT) groups. On day 8 after surgery, compared to the UT, the DT and DMT significantly improved myocardial salvage, owing to the suppression of macrophage infiltration and apoptosis. After the 10-week treatment, the DT and DMT exhibited decreased heart rate, reduced myocardial infarct size, attenuated cardiac dysfunction, and decreased plasma levels of brain natriuretic peptide and catecholamine, thereby preventing subsequent CHF. These results suggest that donepezil monotherapy or combined therapy with β-blocker may be an alternative pharmacotherapy post-RMI.

Abstract
BACKGROUND There are concerns of delays in ST-segment elevation myocardial infarction (STEMI) care during the COVID-19 pandemic. It is unclear whether the care and outcomes of STEMI patients differ between COVID-19 waves and compared with historical periods. METHODS Consecutive patients in the Vancouver Coastal Health Authority STEMI database were included to compare care during 3 distinct waves of the COVID-19 pandemic (9 months; March 2020 to January 2021) with an historical non-COVID-19 cohort. We compared STEMI incidence, baseline characteristics, and outcomes between groups. We also examined time from first medical contact (FMC) to reperfusion, symptom to FMC, and FMC to STEMI diagnosis, as well as predictors of delays. RESULTS The incidence of STEMI was similar during COVID-19 (n = 305; mean 0.93/day) and before COVID-19 (n = 949; 0.97/day; P = 0.80). The COVID-19 cohort showed significant delay in FMC-to-reperfusion (median 116 min vs 102 min; P < 0.001) and FMC-to-STEMI diagnosis (median 17 mins vs 11 min; P < 0.001). Delays in FMC-to-device times worsened across the 3 COVID-19 waves (FMC-to-device time ≤ 90 min in wave 1: 32.9%; in wave 2: 25.6%; in wave 3: 16.3%; P = 0.045 [47.5% before COVID-19; P < 0.001]). There were no significant predictors of delay were unique to the COVID-19 cohort. CONCLUSIONS This study demonstrates delays in reperfusion during the COVID-19 pandemic compared with the historical control, with delays increasing during subsequent waves within the pandemic. It is critical to further understand these care gaps to improve STEMI care for future waves of the current and future pandemics.

Abstract
Introduction The coronavirus disease 2019 (COVID-19) pandemic situation is a state that has had a great impact on the medical system and society. To respond to the pandemic situation, various methods, such as a pre-triage system, are being implemented in the emergency medical field. However, there are insufficient studies on the effects of this pandemic situation on patients visiting the emergency department (ED), especially those with cardio/cerebrovascular diseases (CVD)1 classified as time-dependent emergencies. Methods We performed a retrospective analysis of a cohort of patients from April 2020 to December 2020 (April 2020 was when the pre-triage system was established) compared to a parallel comparison patient cohort from 2019. The primary outcome was in-hospital mortality. CVD was defined by the patient's final diagnosis. Results During the same period, the number of patients who had visited the ED after COVID-19 had decreased to 79.1% of the number of patients who had visited the ED before COVID-19. The overall patient mortality and the mortality in the patients cardiovascular disease had both increased, while the mortality from cerebrovascular disease did not increase. Meanwhile, the ED length of stay had increased in all patients but did not increase in the patients with cardiovascular disease. Conclusion As with prior studies conducted in other regions, in our study, the total number of ED visits were decreased compared to before COVID-19. The overall mortality had increased, particularly in the patients with cardiovascular disease.

Abstract
In rats anesthetized with α-chloralose, coronary artery occlusion (45 min) and reperfusion (120 min) were modeled. The selective δ2-opioid receptor agonist deltorphin II was administered 5 min before reperfusion. Protein kinase C inhibitor chelerythrine, AMP-activated protein kinase inhibitor compound C, and ATP-sensitive K+ channel blockers glibenclamide, 5-hydroxydecanoate, and HMR 1098 were administered 10 min before reperfusion. It was found that the infarct-limiting effect of deltorphin II is associated with activation of protein kinase C and opening of sarcolemmal ATP-sensitive K+ channel.

Abstract
OBJECTIVE To describe the duration of the pre-hospital delay time and identify factors associated with prolonged pre-hospital delay in patients with acute myocardial infarction (AMI) in China. METHODS Data were collected from November 2014 to December 2019 as part of the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project. A total of 33,386 patients with AMI admitted to the index hospitals were included in this study. Two-level logistic regression was conducted to explore the factors associated with the pre-hospital delay and the associations between different pre-hospital delay and in-hospital outcomes. RESULTS Of the 33,386 patients with AMI, 70.7% of patients arrived at hospital ≥ 2 h after symptom onset. Old age, female, rural medical insurance, symptom onset at early dawn, and non-use of an ambulance predicted a prolonged pre-hospital delay (all P < 0.05). Hypertension and heart failure at admission were only significant in predicting a longer delay in patients with ST-segment elevation myocardial infarction (STEMI) (all P < 0.05). A pre-hospital delay of ≥ 2 h was associated with an increased risk of mortality [odds ratio (OR) = 1.36, 95% CI: 1.09-1.69, P = 0.006] and major adverse cardiovascular events (OR = 1.22, 95% CI: 1.02-1.47, P = 0.033) in patients with STEMI compared with a pre-hospital delay of < 2 h. CONCLUSIONS Prolonged pre-hospital delay is associated with adverse in-hospital outcomes in patients with STEMI in China. Our study identifies that patient characteristics, symptom onset time, and type of transportation are associated with pre-hospital delay time, and provides focuses for quality improvement.

Abstract
BACKGROUND The clinical efficacy of the Impella for high-risk percutaneous coronary intervention (PCI) and cardiogenic shock remains under debate. We thus sought to investigate the protective effects on the heart with the Impella's early use pre-PCI using cardiac magnetic resonance imaging (CMRI). METHODS We retrospectively evaluated the difference in the subacute phase CMR imaging results (19 ± 9 days after admission) between patients undergoing an Impella (n = 7) or not (non-Impella group: n = 18 [12 intra-aortic balloon pumps (1 plus veno-arterial extracorporeal membrane oxygenation) and 6 no mechanical circulation systems]) in broad anterior ST-elevation myocardial infarction (STEMI) cases. A mechanical circulation system was implanted pre-PCI. RESULTS No differences were found in the door-to-balloon time, peak creatine kinase, and hospital admission days between the Impella and non-Impella groups; however, the CMRI-derived left ventricular ejection fraction was significantly greater (45 ± 13% vs. 34 ± 7.6%, P = 0.034) and end-diastolic and systolic volumes smaller in the Impella group (149 ± 29 vs. 187 ± 41 mL, P = 0.006: 80 ± 29 vs. 121 ± 40 mL, P = 0.012). Although the global longitudinal peak strain did not differ, the global radial (GRS) and circumferential peak strain (GCS) were significantly higher in the IMPELLA than non-IMPELLA group. Greater systolic and diastolic strain rates (SRs) in the Impella than non-Impella group were observed in non-infarcted rather than infarcted areas. CONCLUSIONS Early implantation of an Impella before PCIs for STEMIs sub-acutely prevented cardiac dysfunction through preserving the GRS, GCS, and systolic and diastolic SRs in the remote myocardium. This study provided mechanistic insight into understanding the usefulness of the Impella to prevent future heart failure.

Recombinant Klotho Protein Ameliorates Myocardial Ischemia/Reperfusion Injury by Attenuating Sterile Inflammation. Biomedicines 2022; 10:biomedicines10040894. [PMID: 35453645 PMCID: PMC9032004 DOI: 10.3390/biomedicines10040894] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 03/31/2022] [Accepted: 04/08/2022] [Indexed: 02/01/2023] Open
Abstract
Currently, no effective therapy and potential target have been elucidated for preventing myocardial ischemia and reperfusion injury (I/R). We hypothesized that the administration of recombinant klotho (rKL) protein could attenuate the sterile inflammation in peri-infarct regions by inhibiting the extracellular release of high mobility group box-1 (HMGB1). This hypothesis was examined using a rat coronary artery ligation model. Rats were divided into sham, sham+ rKL, I/R, and I/R+ rKL groups (n = 5/group). Administration of rKL protein reduced infarct volume and attenuated extracellular release of HMGB1 from peri-infarct tissue after myocardial I/R injury. The administration of rKL protein inhibited the expression of pro-inflammatory cytokines in the peri-infarct regions and significantly attenuated apoptosis and production of intracellular reactive oxygen species by myocardial I/R injury. Klotho treatment significantly reduced the increase in the levels of circulating HMGB1 in blood at 4 h after myocardial ischemia. rKL regulated the levels of inflammation-related proteins. This is the first study to suggest that exogenous administration of rKL exerts myocardial protection effects after I/R injury and provides new mechanistic insights into rKL that can provide the theoretical basis for clinical application of new adjunctive modality for critical care of acute myocardial infarction.

Abstract
INTRODUCTION Ischemic heart disease is the leading cause of death worldwide, and interventions to reduce myocardial infarction (MI) complications are widely researched. Photobiomodulation therapy (PBMT) has altered multiple biological processes in tissues and organs, including the heart. OBJECTIVES This study aimed to assess the temporal effects of PBMT on cardiac fibrosis activation after MI in rats. In this proof-of-concept study, we monitored the change in expression patterns over time of genes and microRNAs (miRNAs) involved in the formation of cardiac fibrosis post-MI submitted to PBMT. MATERIALS AND METHODS Experimental MI was induced, and PBMT was applied shortly after coronary artery ligation (laser light of wavelength 660 nm, 15 mW of power, energy density 22.5 J/cm2 , 60 seconds of application, irradiated area 0.785 cm2 , fluence 1.1 J/cm2 ). Ventricular septal samples were collected at 30 minutes, 3, 6, 24 hours, and 3 days post-MI to determine temporal PBMT's effects on messenger RNA (mRNA) expression associated with cardiac fibrosis activation and miRNAs expression. RESULTS PBMT, when applied after ischemia, reversed the changes in mRNA expression of myocardial extracellular matrix genes induced by MI. Surprisingly, PBMT modified cardiac miRNAs expression related to fibrosis replacement in the myocardium. Expression correlations between myocardial mRNAs were assessed. The correlation coefficient between miRNAs and target mRNAs was also determined. A positive correlation was detected among miR-21 and transforming growth factor beta-1 mRNA. The miR-29a expression negatively correlated to Col1a1, Col3a1, and MMP-2 mRNA expressions. In addition, we observed that miR-133 and Col1a1 mRNA were negatively correlated. CONCLUSION The results suggest that PBMT, through the modulation of gene transcription and miRNA expressions, can interfere in cardiac fibrosis activation after MI, mainly reversing the signaling pathway of profibrotic genes.

[PMID: 34800289 DOI: 10.1111/eci.13719] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 11/09/2021] [Accepted: 11/16/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND No-/slow-reflow phenomenon (NRP) is a severe complication in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). This study aimed to explore the relationship between elevated serum uric acid (SUA) and NRP in patients with STEMI undergoing pPCI, focusing on inflammation and angiographic findings. METHODS A total of 610 patients who received pPCI for STEMI were retrospectively enrolled. Patients were divided into a hyperuricaemia group and a non-hyperuricaemia group according to SUA levels. Clinical information and angiographic indicators were compared between the two groups. Thrombolysis in myocardial infarction (TIMI) flow and TIMI myocardial perfusion grade (TMPG) <3 after stent implantation were defined as TIMI-NRP and TMPG-NRP, respectively. A logistic model was used to analyse the relationship between hyperuricaemia and NRP. RESULTS The hyperuricaemia group had a higher incidence of TIMI-NRP (24.9% vs 14.0%, p < .001) and TMPG-NRP (33.0% vs 24.9%, p = .03), higher levels of C-reactive protein (7.2 vs 4.1 mg/L, p < .001) and worse left ventricular ejection fraction (51.5% vs 54.0%, p = .002) than the non-hyperuricaemia group. As for angiographic findings, there was no significant difference between the two groups in terms of lesion characteristics measured by quantitative coronary angiography. After multivariable adjustment, elevated SUA was significantly associated with TIMI-NRP (odds ratio: 1.94, 95% confidence interval: 1.24-3.01, p = .003). Subgroup analysis showed that the effect of hyperuricaemia in TIMI-NRP was more pronounced in patients with delayed perfusion as well as in patients with diabetes mellitus. CONCLUSIONS Elevated SUA is associated with severe inflammation and has higher incidence of TIMI-NRP in patients with STEMI undergoing pPCI, especially in those with delayed perfusion or diabetes mellitus.

Abstract
Introduction A dedicated relationship between total ischemic time (TIT) and clinical outcomes has been reported in ST-elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI); however, this claim is yet to be clarified. Accordingly, this study was carried out to determine the association of TIT with in-hospital and one-year follow-up outcomes in STEMI patients undergoing primary PCI. Material and methodology Between December 2020 and December 2021, a total of 113 consecutive STEMI patients undergoing primary PCI were prospectively included. According to TIT, all patients were categorized into two groups: (a) shorter TIT (<180 minutes) and (b) prolonged TIT (≥180 minutes). Data regarding baseline, clinical, and angiographic characteristics, as well as in-hospital and one-year follow-up outcomes were noted among the two groups. Results A total of 113 STEMI patients with a mean age of 69.3 ± 13.6 years were studied, and males [92 (81.4%)] were predominately affected with STEMI. A median TIT was 348 minutes. Of 113, 30 (23.0%) patients had a TIT of <180 minutes and 83 (73.5%) had a TIT of ≥180 minutes. Prolonged ischemia duration was significantly associated with composite of death, rehospitalization, and revascularization (p=0.02) at one-year follow-up. Conclusion TIT can be considered a good quality indicator, together with door-to-balloon time and other clinical determinants, in order to improve survival in STEMI patients.

Abstract
BackgroundFirst medical contact (FMC)-to-balloon time is associated with outcome of ST-elevation myocardial infarction (STEMI). We assessed the impact on mortality and the determinants of indirect vs. direct transfer to the cardiac catheterization laboratory (CCL).MethodsWe analyzed data from 2,206 STEMI patients consecutively included in a prospective multiregional percutaneous coronary intervention (PCI) registry. The primary endpoint was 1-year mortality. The impact of indirect admission to CCL on mortality was assessed using Cox models adjusted on FMC-to-balloon time and covariables unequally distributed between groups. A multivariable logistic regression model assessed determinants of indirect transfer.ResultsA total of 359 (16.3%) and 1847 (83.7%) were indirectly and directly admitted for PCI. Indirect admission was associated with higher risk features, different FMCs and suboptimal pre-PCI antithrombotic therapy.At 1-year follow-up, 51 (14.6%) and 137 (7.7%) were dead in the indirect and direct admission groups, respectively (adjusted-HR 1.73; 95% CI 1.22–2.45). The association of indirect admission with mortality was independent of pre-FMC and FMC characteristics. Older age, paramedics- and private physician-FMCs were independent determinants of indirect admission (adjusted-HRs 1.02 per year, 95% CI 1.003–1.03; 5.94, 95% CI 5.94 3.89–9.01; 3.41; 95% CI 1.86–6.2, respectively).ConclusionsOur study showed that, indirect admission to PCI for STEMI is associated with 1-year mortality independent of FMC to balloon time and should be considered as an indicator of quality of care. Indirect admission is associated with higher-risk features and suboptimal antithrombotic therapy. Older age, paramedics-FMC and self-presentation to a private physician were independently associated with indirect admission. Our study, supports population education especially targeting elderly, more adequately dispatched FMC and improved pre-CCL management.

Abstract
Over the past decades, the treatment of ST-segment elevation myocardial infarction (STEMI) has been redefined with the incorporation of evidence from multiple clinical trials. Recommendations from guidelines are updated regularly to reduce morbidity and mortality. However, heterogeneous care systems, physician perspectives, and patient behavior still lead to a disparity between evidence and clinical practice. The quality of care has been established and become an integral part of modern healthcare in order to increase the likelihood of desired health outcomes and adhere to professional knowledge. For patients with STEMI, measuring the quality of care is a multifactorial and multidimensional process that cannot be estimated solely based on patients' clinical outcomes. The care of STEMI is similar to the concept of "the chain of survival" that emphasizes the importance of seamless integration of five links: early recognition and diagnosis, timely reperfusion, evidence-based medications, control of cholesterol, and cardiac rehabilitation. Serial quality indicators, reflecting the full spectrum of care, have become a widely used tool for assessing performance. Comprehension of every aspect of quality assessment and indicators might be too demanding for a physician. However, it is worthwhile to understand the concepts involved in quality improvement since every physician wants to provide better care for their patients. This article reviews a fundamental approach to quality care in STEMI.

Impact of Total Ischemic Time on the Recovery of Regional Wall Motion Abnormality after STEMI in the Modern Reperfusion Era. J Interv Cardiol 2022; 2022:2447707.

Abstract
Background Total ischemic time (TIT) is an important factor for predicting mortality among patients with ST-segment elevation myocardial infarction (STEMI). However, the correlation between TIT and the extent of wall motion abnormality has not been well studied. Therefore, we investigated changes in the wall motion score index (WMSI) value based on TIT in STEMI patients who underwent primary percutaneous coronary intervention (PCI) and subsequent transthoracic echocardiography. Methods STEMI patients who underwent primary PCI and follow-up coronary angiography were analyzed after the exclusion of cases of in-stent restenosis (ISR). WMSI values were calculated by dividing the sum of scores by the number of segments visualized. Results A total of 189 patients underwent primary PCI for STEMI, and 151 had no ISR with a median follow-up of 12.3 months. TIT was 180 (117–369) minutes in a subset of 151 patients (mean age of 62 years; 76% male). Among patients without ISR, 109 (72%) demonstrated a decrease in the WMSI value during the follow-up period. The WMSI values of patients with TITs of 180 minutes or less were significantly decreased relative to those among patients with TITs of greater than 180 minutes (p=0.020). Among patients with TITs of 180 minutes or less, the TIT was significantly shorter among those with a reduction in the WMSI value than among those with an increase in the WMSI value (106 [81–124] vs. 133 [100–151] minutes; p=0.018). TIT was an independent predictor for a reduction in the WMSI value among these patients (adjusted hazard ratio: 0.976 (0.957–0.995); p=0.016). Conclusions In the modern reperfusion era of STEMI, patients with TITs of 180 minutes or less experienced a significant degree of recovery from regional wall motion abnormalities.

Abstract
Background The current study aimed to evaluate changes in treatment delay and outcome for ST-segment elevation myocardial infarction (STEMI) in the Netherlands during the first coronavirus disease 2019 (COVID-19) outbreak, thereby comparing regions with a high and low COVID-19 hospitalisation rate. Methods Clinical characteristics, STEMI timing variables, 30-day all-cause mortality and cardiovascular complications of all consecutive patients admitted for STEMI from 1 January to 30 June in 2020 and 2019 to six hospitals performing a high volume of percutaneous coronary interventions were collected retrospectively using data from the Netherlands Heart Registry, hospital records and ambulance report forms. Patient delay, pre-hospital delay and door-to-balloon time before and after the outbreak of COVID-19 were compared to the equivalent periods in 2019. Results A total of 2169 patients were included. During the outbreak median total treatment delay significantly increased (2 h 51 min vs 2 h 32 min; p = 0.043) due to an increased patient delay (1 h 20 min vs 1 h; p = 0.030) with more late presentations > 24 h (1.1% vs 0.3%) in 2020. This increase was particularly evident during the peak phase of COVID-19 in regions with a high COVID-19 hospitalisation rate. During the peak phase door-to-balloon time was shorter (38 min vs 43 min; p = 0.042) than in 2019. All-cause 30-day mortality was comparable in both time frames (7.8% vs 7.3%; p = 0.797). Conclusions During the outbreak of COVID-19 patient delay caused an increase in total ischaemic time for STEMI, with a more pronounced delay in high-endemic regions, stressing the importance of good patient education during comparable crisis situations.

Abstract
Background The prognostic implications of the admission cTnI level and D2B time combined on in-hospital and 1-year heart failure (HF) and mortality in STEMI patients undergoing a primary percutaneous coronary intervention (PCI) are remain uncertain. Methods and Results We divided the consecutive 1485 STEMI patients who underwent PCI from January 2015 to October 2019 at our hospital into three groups based on their admission cTnI levels: normal group (<0.1 ng/mL), middle group (0.1 to less than 3 ng/mL), and high group (≥3 ng/mL) and into two groups by their D2B times: >90 min (>90-D2B) and ≤90 min (≤90-D2B). During the in-hospital and 1-year follow-up periods, the incidence of composite clinical events increased significantly with the increase in the admission cTnI level (p < 0.05). In-hospital, the composite rate of death and HF events was significantly higher in the >90-D2B group compared to the ≤90-D2B group (p = 0.006), but its influence disappeared in the 1-year follow-up (p > 0.05). A multivariable logistic analysis revealed that, in the ≤90-D2B group, with the exception of the cTnI ≥3 ng/mL patients, the cTnI level had no effect on in-hospital or 1-year outcomes; in >90-D2B group, cTnI ≥3ng/mL increased outcomes in both periods. Conclusion High cTnI levels (≥3 ng/mL) on admission are independent of the D2B time for predicting in-hospital and 1-year cardiac events in STEMI patients undergoing PCI.

Relation of Pain-to-Balloon Time and Mortality in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention. Am J Cardiol 2022; 163:38-42. [PMID: 34763825 DOI: 10.1016/j.amjcard.2021.09.039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 09/16/2021] [Accepted: 09/20/2021] [Indexed: 11/24/2022]
Abstract
Limited and inconsistent data are present regarding the importance of the time delay between symptom onset and balloon inflation in ST-segment elevation myocardial infarction (STEMI) patients. We aimed to investigate the possible influence of prolonging pain-to-balloon times (PBT) on in-hospital outcomes and mortality in a large cohort of patients with STEMI undergoing primary percutaneous coronary intervention. We retrospectively studied 2,345 STEMI patients (age 61 ± 13 years, 82% men) who underwent primary percutaneous coronary intervention. Patients were stratified according to PBT into 3 groups: ≤120 minutes, 121 to 360 minutes, and >360 minutes. Patients' records were assessed for the occurrence of in-hospital complications, 30-day, and 1-year mortality. Of the 2,345 study patients, 36% had PBT time ≤120 minutes, 40% had PBT of 121 to 360 minutes and 24% had PBT time >360 minutes. The major part of the total PBT (average 358 minutes) was caused by the time interval from symptom onset to hospital arrival, namely, pain-to-door time (average 312 minutes) in all 3 groups. Longer PBT was associated with a lower left ventricular ejection fraction, higher incidence of in-hospital complications, and higher 30-day mortality. In 2 multivariate cox regression models, a per-hour increase in PBT (hazard ratio 1.03 [95% confidence interval 1.00 to 1.06], p = 0.039) as well as PBT >360 minutes (hazard ratio 1.6 [95% confidence interval 1.1 to 2.5], p = 0.04) were both independently associated with an increased risk for 1-year mortality. In conclusion, PBT may be an accurate and independent marker for adverse events, pointing to the importance of coronary reperfusion as early as possible based on the onset of pain.

Abstract
BACKGROUND The Chest Pain-MI registry affords a 10-year perspective of the acute myocardial infarction (MI) patient characteristics, management, and clinical outcomes in the United States. We report the changes in the treatment and cardiovascular outcomes of acute MI patients over 10 years. METHODS Annual trends in patient characteristics, in-hospital treatment, and outcomes of 604 936 ST-segment-elevation MI (STEMI) and 933 755 non-ST-segment-elevation MI (NSTEMI) patients at 1230 hospitals from 2009 to 2018 were analyzed. Using the validated Acute Coronary Intervention and Outcomes Network mortality risk model, trends in in-hospital risk-adjusted mortality rates were tested between 2011 and 2018. RESULTS Over 10 years, the prevalence of diabetes (22.8%-28.3% [STEMI] and 35.7%-41.3% [NSTEMI]) and atrial fibrillation (4.1%-6.1% and 9.4%-11.7%) increased, whereas the prevalence of smoking decreased (43.5%-37.9% and 30.2%-27.5%, P<0.001 for all) in patients with STEMI and NSTEMI, respectively. Among eligible patients with STEMI, primary percutaneous coronary intervention use increased (82.3%-96.0%) with shorter median first medical contact to device time (90 to 82 minutes, P<0.001). Among patients with NSTEMI, percutaneous coronary intervention use increased significantly (43.9%-54.5%, P<0.001). Adherence to guideline-directed medical therapies improved in both groups. From 2011 to 2018, risk-adjusted mortality rate (2.8%-2.7%, P=0.46) was stable in STEMI and declined significantly in patients with NSTEMI (1.9%-1.3%, P=0.0001). CONCLUSIONS Risk factors of patients presenting with acute MI have changed modestly while treatment improved over time. Risk-adjusted mortality rates remained stable for patients with STEMI and declined significantly for patients with NSTEMI.

Abstract
High mortality among people with acute myocardial infarction is one of the most urgent problems of modern cardiology. And in recent years, much attention has been paid to the search for pharmacological approaches to prevent heart damage. In this review, we tried to analyze data on the effect of P2Y12 receptor antagonists on the ischemia/reperfusion tolerance of the heart. Ischemic and reperfusion injuries of the heart underlie the pathogenesis of acute myocardial infarction (AMI) and sudden cardiac death. The mortality rate is still high and is 5–7% in patients with ST-segment elevation myocardial infarction. The review is devoted to pharmacological approaches to limitation of ischemic and reperfusion injuries of the heart. The article analyzes experimental evidence and the clinical data on the effects of P2Y12 receptor antagonists on the heart’s tolerance to ischemia/reperfusion in animals with coronary artery occlusion and reperfusion and also in patients with AMI. Chronic administration of ticagrelor prevented adverse remodeling of the heart. There is evidence that sphingosine-1-phosphate is the molecule that mediates the infarct-reducing effect of P2Y12 receptor antagonists. It was discussed a role of adenosine in the cardioprotective effect of ticagrelor.

Abstract
Background Acute heart failure and cardiogenic shock remain highly morbid conditions despite prompt medical therapy in critical care settings. Mechanical circulatory support (MCS) is a promising therapy for these patients, yet remains managed with open-loop control. Continuous measure of cardiac function would support and optimize MCS deployment and weaning. The nature of indwelling MCS provides a platform for attaining this information. This study investigates how hysteresis modeling derived from MCS device signals can be used to assess contractility changes to provide continuous indication of changing cardiac state. Load-dependent MCS devices vary their operation with cardiac state to yield a device–heart hysteretic interaction. Predicting and examining this hysteric relation provides insight into cardiac state and can be separated by cardiac cycle phases. Here, we demonstrate this by predicting hysteresis and using the systolic portion of the hysteresis loop to estimate changes in native contractility. This study quantified this measurement as the enclosed area of the systolic portion of the hysteresis loop and correlated it with other widely accepted contractility metrics in animal studies (n = 4) using acute interventions that alter inotropy, including a heart failure model. Clinical validation was performed in patients (n = 8) undergoing Impella support. Results Hysteresis is well estimated from device signals alone (r = 0.92, limits of agreement: − 0.18 to 0.18). Quantified systolic area was well correlated in animal studies with end-systolic pressure–volume relationship (r = 0.84), preload recruitable stroke work index (r = 0.77), and maximum slope of left ventricular pressure (dP/dtmax) (r = 0.95) across a range of inotropic conditions. Comparable results were seen in patients with dP/dtmax (r = 0.88). Diagnostic capability from ROC analysis yielded AUC measurements of 0.92 and 0.90 in animal and patients, respectively. Conclusions Mechanical circulatory support hysteretic behavior can be well modeled using device signals and used to estimate contractility changes. Contractility estimate is correlated with other accepted metrics, captures temporal trends that elucidate changing cardiac state, and is able to accurately indicate changes in inotropy. Inherently available during MCS deployment, this measure will guide titration and inform need for further intervention.

Abstract
Heart failure is a progressive disease that is associated with repeated exacerbations and hospitalizations. The rapid increase in the number of heart failure patients is a global health problem known as the 'heart failure pandemic'. To control the pandemic, multifaceted approaches are essential, ranging from prevention of onset to long-term disease management. Especially in patients with moderate to severe heart failure (stages C and D), surgical and catheter-based interventions are prerequisites for saving lives, preserving cardiac function, improving quality of life (QOL), and prognosis. In addition, various new medical technologies for these interventions have been clinically applied and have been shown to be effective against symptoms and improve the QOL and prognosis of patients with heart failure. Furthermore, the concept of interventional heart failure (IHF) therapy, which considers heart recovery and prevention of worsening of heart failure via multidisciplinary treatment using surgical, catheter interventions, and mechanical circulatory support devices, has been proposed worldwide. This review discusses the importance of IHF therapy in heart failure management, recent changes in interventional technologies and strategies for patients with heart failure, and worldwide education attempts for IHF specialists.

Abstract
During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with ST-elevation myocardial infarction (STEMI) should be treated as possibly infected individuals. Therefore, more time is considered necessary to conduct primary percutaneous coronary intervention (PCI). In this study, we sought to evaluate the impact of the SARS-CoV-2 pandemic on primary PCI for STEMI. Between March 2019 and March 2021, 259 patients with STEMI underwent primary PCI. Patients were divided into 2 groups: the pre-pandemic group (March 2019-February 2020) and the pandemic group (March 2020-February 2021). The patient demographics, reperfusion time including onset-to-door time, door-to-balloon time (DTBT), computed tomography (CT), peak creatinine phosphokinase (CPK), and 30-day mortality rate were investigated. The mean age of the patients was 70.4 ± 12.9 years, and 71.6% were male. There were 117 patients before the pandemic and 142 during the pandemic. The median DTBT was 29 (21.25-41.25) minutes before the pandemic and 48 minutes (31-73 minutes) during the pandemic (P < 0.001). The median door-to-catheter-laboratory time was 13.5 (10-18.75) minutes before the pandemic and 29.5 (18-47.25) minutes during the pandemic (P < 0.001). CT evaluation was performed before PCI in 39 (33.3%) patients and 63 (44.4%) patients (P = 0.08); their peak CPK levels were 1480 (358-2737.5) IU and 1363 (621-2722.75) IU (P = 0.56), and the 30-day mortality rates were 4.3% and 2.1% (P = 0.48), respectively. The SARS-CoV-2 pandemic changed the diagnostic procedure in the emergency department and affected the DTBT in patients with STEMI. Nonetheless, no adverse effects on the 30-day mortality rate were observed.

Abstract
BACKGROUND ST-elevation myocardial infarction (STEMI) is a life-threatening medical emergency that requires immediate medical attention. Each hospital should implement a clinical pathway with the main objective to reduce ischemia time from diagnosis to revascularization (because this has shown to save myocardial tissues and, subsequently, patients' lives), utilizing the most evidence-based approach and the most up-to-date management protocol. In this study, we aimed to assess the utility of structuring chest pain pathway (CPP) with the instantaneous case-by-case feedback protocol using WhatsApp and its impact on improving 2 major key performance indicators-the impact on initial emergency room (ER) door-to-electrocardiogram (ECG) time, and door-to-balloon time-in a predefined 6-month corrective action period. METHODS A prospective, quality improvement plan was set to reduce door-to-first-ECG and door-to-balloon times to less than 10 and 90 minutes, respectively, in all acute coronary syndrome cases (including STEMI cases), from August 2020 to April 30, 2021. Several measures were done to attain the goal, including strict compliance to CPP with documentation, ruling out possible mimickers, and reducing false activation and time delays in ER. Direct feedback on cases was provided using WhatsApp messaging app on smartphones; protocol and results of time lines were accessed by all healthcare providers associated with CPP, including ER nurses, ER doctors, Cardiology residents, specialists, Catheterization laboratory nurses, technicians, and interventionalists. Bimonthly meetings with all stake holders were reinforced, and minutes of meeting were reviewed and corrective actions were implemented the next day. On a daily basis, all cases were analyzed and tabulated by a dedicated nurse and a doctor from ER, and another nurse and doctor from the quality assurance department. RESULTS After a 6-month period of implementing improvement plan and sticking to a comprehensive chest pain clinical pathways strategy with a case-by-case review on a shared smartphone messaging application, the rate of door-to-first-ECG improved from 76% to 93% in patients with chest pain, and the door-to-balloon time targeting less than 90 minutes improved significantly from only 77% to 92% in STEMI patients. This was statistically significant with a P value of 0.0001 and 0.001, respectively, and the rate of false activation was reduced from 23% to 16% and 10% 3 and 6 months of time, respectively, with a significant P value of <0.01. Finally, a strict 100% rate of timely documentation on patients with chest pain was achieved. CONCLUSIONS An improvement plan of implementing the CPP, cut-time policy, and using smartphone WhatsApp messaging for a case-to-case instantaneous feedback has significantly improved key performance indicators and, subsequently, ischemia time in acute coronary syndrome patients (including STEMI patients) in 6 months time, indicating that this strategy works.

Abstract
Pyroptosis has been implicated in the pathophysiology of myocardial infarction (MI) in rodents, but its contribution to reperfusion injury in MI patients is unclear. Here, we evaluated pyroptosis in MI patients in vitro and in vivo models of myocardial ischemia/reperfusion (I/R) injury. We also investigated the molecular mechanisms that regulate pyroptosis and myocardial I/R injury in these in vitro and in vivo models. The study showed that MI patients exhibited elevated serum concentrations of the pyroptosis-related pro-inflammatory cytokines IL-1β and IL-18. Increased levels of IL-1β and IL-18 as well as the pyroptosis-related inflammatory caspases (caspase-1 and 11) were detected in cultured cardiomyocytes after anoxia/reoxygenation (A/R) and in cardiac tissues after I/R. Circ-NNT and USP46 were upregulated while miR-33a-5p was downregulated in MI patients, as well as in cultured cardiomyocytes after A/R and cardiac tissues after I/R. Circ-NNT or USP46 knockdown or miR-33a-5p overexpression inhibited the expression of pro-caspase-1, cleaved caspase-1, pro-caspase-11, cleaved caspase-11, IL-1β, and IL-18 in A/R cardiomyocytes and attenuated myocardial infarction in I/R mice. The results from luciferase reporter assays and gene overexpression/knockdown studies indicated that miR-33a-5p directly targets USP46, and circ-NNT regulates USP46 by acting as a miR-33a-5p sponge. Direct association between circ-NNT and miR-33a-5p in cardiomyocytes was confirmed by pull-down assays. In summary, pyroptosis is activated during myocardial I/R and contributes to reperfusion injury. Circ-NNT promotes pyroptosis and myocardial I/R injury by acting as a miR-33a-5p sponge to regulate USP46. This circ-NNT→miR-33a-5p→USP46 signaling axis may serve as a potential target for the development of cardio-protective agents to improve the clinical outcome of reperfusion therapy.

Abstract
Though alprostadil has been reported to improve the impaired microcirculation of patients with pulmonary arterial hypertension, its effectiveness as a treatment for coronary microvasculature dysfunction (CMD) following ST-segment elevation myocardial infarction (STEMI) is unknown. A total of 18 miniature pigs with CMD following STEMI were randomized into three groups that received an intracoronary injection of 5 ml of normal saline, 2 mg of nicorandil or 10 µg of alprostadil immediately after measurement of the index of microcirculatory resistance (IMR) and then an intravenous drip containing 5 ml of normal saline, 2 mg of nicorandil or 10 µg of alprostadil once a day for 6 days. The IMR, cardiac function using ultrasound, infarct areas and heparanase levels in infarct areas were measured and compared between the three groups. The IMR decreased markedly 10 min after alprostadil or nicorandil intracoronary injection (both P<0.05) but not following saline injection (P>0.05). After 7 days, the IMR was substantially lower in the alprostadil and nicorandil groups compared with the saline group (both P<0.05) and the ejection fraction was considerably higher in the alprostadil and nicorandil groups compared with the saline group (both P<0.05). Differences in infarct areas and the relative heparanase expression levels among the 3 groups were similar to the differences in the ejection fraction. No significant differences in the above assessment indexes were identified in the alprostadil and nicorandil groups. Alprostadil infusion improved coronary microcirculation function, reduced the infarct area and limited left ventricular dilatation in a pig coronary microvasculature dysfunction model following STEMI.

Abstract
The emergence of Covid-19 has caused a pandemic and is a major public health concern. Covid-19 has fundamentally challenged the global health care system in all aspects. However, there is a growing concern for the subsequent detrimental effects of continuing delays or adjustments on time-dependent treatments for Covid-19 negative patients. Patients arriving to the ED with STEMIs and acute CVA are currently presumed to have delays due to Covid-19 related concerns. The objective of this paper is to evaluate the implications of the Covid-19 pandemic on non-Covid19 patients in emergency care settings. We conducted a retrospective study from February 2020 to April 2020 and compared this to a parallel period in 2019 to assess the impact of the Covid-19 pandemic on three distinct non-Covid-19 ED diagnosis that require immediate intervention. Our primary outcome measures were time to primary PCI in acute STEMI, time to fibrinolysis in acute CVA, and time to femoral hip fracture correction surgery. Our secondary outcome measure included a composite outcome of length of stay in hospital and mortality. From 1 February 2020 to 30 April 2020, the total referrals to ED diagnosed with STEMI, Hip fracture and CVA of which required intervention were 197 within Covid-19 group 2020 compared to 250 in the control group 2019. Mean duration to intervention (PCI, surgery and tPA, respectively) did not differ between COVID-19 group and 2019 group. Among femoral hip fracture patients', the referral numbers to ED were significantly lower in Covid-19 era (p = 0.040) and the hospitalization stay was significantly shorter (p = 0.003). Among CVA patients', we found statistical differences among the number of referrals and the patients' age. Coping with the Covid-19 pandemic presents a challenge for the general healthcare system. Our results suggest that with proper management, despite the obstacles of isolation policies and social distancing, any negative impact on the quality of health care for the non-Covid-19 patients can be minimized in the emergency department setting.

Abstract
Background Significance of total ischemic time (TIT) in the context of ST-segment elevation myocardial infarction (STEMI) is still controversial. Therefore, in this study, we have evaluate the association of TIT with immediate outcomes in STEMI patients in whom recommended door to balloon (DTB) time of less than 90 min was achieved. Results A total of 5730 patients were included in this study, out of which 80.9% were male and median age was 55 [61–48] years. The median DTB was observed to be 60 [75–45] min and onset of chest pain to emergency room (ER) arrival time was 180 [300–120] min. Prolonged TIT was associated with poor pre-procedure thrombolysis in myocardial infarction (TIMI) flow grade (p = 0.022), number of diseased vessels (p = 0.002), use of intra-aortic balloon pump (p = 0.003), and in-hospital mortality (p = 0.002). Mortality rate was 4.5%, 5.7%, and 7.8% for the patients with TIT of ≤ 120 min, 121 to 240 min, and > 240 min, respectively. Thirty days’ risk of mortality on TIMI score was 4.97 ± 7.09%, 5.01 ± 6.99%, and 7.12 ± 8.64% for the patients with TIT of ≤ 120 min, 121 to 240 min, and > 240 min, respectively.
Conclusions Prolonged total ischemic was associated with higher in-hospital mortality. Therefore, TIT can also be considered in the matrix of focus, along with DTB time and other clinical determinants to improve the survival from STEMI.

Abstract
BACKGROUND Primary percutaneous coronary intervention is the treatment of choice in ST-segment elevation myocardial infarction and no-reflow phenomenon is still an unsolved problem. METHODS We searched PubMed, EmBase, and Cochrane Central Register of Controlled Trials for relevant randomized controlled trials. The primary endpoint was the incidence of major adverse cardiac events and the secondary endpoint was the incidences of no-reflow phenomenon and complete resolution of ST-segment elevation. RESULTS Eighteen randomized controlled trials were enrolled. Nicorandil significantly reduced the incidence of no-reflow phenomenon (OR, 0.46; 95% CI, 0.36-0.59; P < 0.001; I2 = 0%) and major adverse cardiac events (OR, 0.42; 95% CI, 0.27-0.64; P < 0.001; I2 = 52%). For every single outcome of major adverse cardiac events, only heart failure and ventricular arrhythmia were significantly improved with no heterogeneity (OR, 0.36; 95% CI, 0.23-0.57, P < 0.001; OR, 0.43; 95% CI, 0.31-0.60, P < 0.001 respectively). A combination of intracoronary and intravenous nicorandil administration significantly reduced the incidence of major adverse cardiac events with no heterogeneity (OR, 0.24; 95% CI, 0.13-0.43, P < 0.001; I2 = 0%), while a single intravenous administration could not (OR, 0.66; 95% CI, 0.40-1.06, P = 0.09; I2 = 52%). CONCLUSIONS Nicorandil can significantly improve no-reflow phenomenon and major adverse cardiac events in patients undergoing primary percutaneous coronary intervention. The beneficial effects on major adverse cardiac events might be driven by the improvements of heart failure and ventricular arrhythmia. A combination of intracoronary and intravenous administration might be an optimal usage of nicorandil.

Abstract
BACKGROUND Stable coronary artery disease (CAD) patients with myocardial damage have a poor prognosis compared to those without myocardial damage. Recently, malnutrition has been reported to affect the prognosis of cardiovascular diseases. However, the effects of malnutrition on prognosis of CAD patients with myocardial damage remains uncertain. We investigated the effects of malnutrition on prognosis of CAD patients with myocardial damage who received percutaneous coronary intervention (PCI). METHODS Subjects comprised 241 stable CAD patients with myocardial damage due to myocardial ischemia or infraction. Patients underwent successful revascularization for the culprit lesion by PCI using second-generation drug-eluting stents and intravascular ultrasound. The geriatric nutritional risk index (GNRI), which is widely used as a simple method for screening nutritional status using body mass index and serum albumin, was used to assess nutritional status. Associations between major cardiovascular and cerebrovascular events (MACCE) and patient characteristics were assessed. RESULTS Mean GNRI was 100 ± 13, and there were 55 malnourished patients (23%; GNRI < 92) and 186 non-malnourished patients (77%). MACCE occurred within 3 years after PCI in 42 cases (17%), including 34 deaths (14%), and the malnourished group showed a higher rate of MACCE (38%) compared with the non-malnourished group (11%, p < 0.001). Univariate Cox proportional hazards analyses showed that MACCE was associated with age [hazard ratio (HR), 1.04; 95% confidence interval (CI), 1.04-1.07; p = 0.004], prior heart failure (HR 2.35; 95% CI 1.10-5.01; p = 0.027), high-sensitivity C-reactive protein (HR 1.08; 95% CI 1.03-1.11; p < 0.001), hemodialysis (HR 2.63; 95% CI 1.51-4.58; p < 0.001) and malnutrition (HR 3.69; 95% CI 2.11-6.42; p < 0.001). Multivariate Cox proportional hazards analysis revealed hemodialysis (HR 2.17; 95% CI 1.19-3.93; p = 0.011) and malnutrition (HR 2.30; 95% CI 1.13-4.67; p = 0.020) as significantly associated with MACCE. Furthermore, Cox proportional hazards models using malnutrition and hemodialysis revealed that patients with malnutrition and hemodialysis were at greater risk of MACCE after PCI than patients with neither malnutrition nor hemodialysis (HR 6.91; 95% CI 3.29-14.54; p < 0.001). CONCLUSIONS In CAD patients with myocardial damage, malnutrition (GNRI < 92) represents an independent risk factor for MACCE. Assessment of nutritional status may help stratify the risk of cardiovascular events and encourage improvements in nutritional status.

Abstract
BACKGROUND The first Covid-19 epidemic outbreak has enormously impacted the delivery of clinical healthcare and hospital management practices in most of the hospitals around the world. In this context, it is important to assess whether the clinical management of non-Covid patients has not been compromised. Among non-Covid cases, patients with Acute Myocardial Infarction (AMI) and stroke need non-deferrable emergency care and are the natural candidates to be studied. Preliminary evidence suggests that the time from onset of symptoms to emergency department (ED) presentation has significantly increased in Covid-19 times as well as the 30-day mortality and in-hospital mortality. METHODS We check, in a causal inference framework, the causal effect of the hospital's stress generated by Covid-19 pandemic on in-hospital mortality rates (primary end-point of the study) of AMI and stroke over several time-windows of 15-days around the implementation date of the State of Emergency restrictions for COVID-19 (March, 9th 2020) using two quasi-experimental approaches, regression-discontinuity design (RDD) and difference-in-regression-discontinuity (DRD) designs. Data are drawn from Spedali Civili of Brescia, one of the most hit provinces in Italy by Covid-19 during March and May 2020. FINDINGS Despite the potential adverse effects on expected mortality due to a longer time to hospitalization and staff extra-burden generated by the first wave of Covid-19, the AMI and stroke mortality rates are overall not statistically different during the first wave of Covid-19 than before the first peak. The obtained results provided by RDD models are robust also when we account for seasonality and unobserved factors with DRD models. INTERPRETATION The non-statistically significant impact on mortality rates for AMI and stroke patients provides evidence of the hospital ability to manage -with the implementation of a dual track organization- the simultaneous delivery of high-quality cares to both Covid and non-Covid patients.

Mechanical Complications in ST-Elevation Myocardial Infarction (STEMI) Based on Different Reperfusion Strategies. Am J Cardiol 2021; 156:79-84.

Abstract
Contemporary trends of mechanical complications like papillary muscle rupture (PMR), ventricular septal defect/rupture (VSR), and free wall rupture (FWR) in ST-elevation m'yocardial infarction (STEMI), especially in the era of primary percutaneous coronary interventions (PPCI) has not been definitively investigated. We utilized the National Inpatient Sample (NIS) database from years 2003 to 2017 using International Classification of Disease 9th and 10th revision (ICD-9 and ICD-10) codes to identify STEMI patients undergoing PPCI, fibrinolysis alone, and fibrinolysis with subsequent PCI. We identified those developing in-hospital PMR /VSD / FWR. We identified a total of 2,034,153 STEMI patients where 93.5% had PPCI, 3.2% had fibrinolysis alone, and 3.3% had fibrinolysis with subsequent PCI. Rates of all mechanical complications was low for all three different reperfusion strategies evaluated, with downward trends (p <0.05) over time. No statistically significant difference in the rates of mechanical complication was noted among patients treated with different reperfusion strategies on multivariable logistic regression models. In conclusion, in a contemporary cohort of US patients-majority of whom were managed with PPCI, the rates of overall mechanical complications after STEMI were low even with initial use of fibrinolytics and exhibited a downward temporal trend.
