Abstract
OBJECTIVE To assess the trends and impact of changes in management of ST Elevation Myocardial Infarction (STEMI) from 2010 to 2019. DESIGN Retrospective analysis of data from STEMI hospitalisations including demographic, comorbidity, angiographic and outcome data. SETTING/PARTICIPANTS High-volume non-surgical regional Australian tertiary referral centre. MAIN OUTCOME MEASUREMENTS Index & 12-month mortality (all-cause & cardiovascular), door-to-balloon time, target-vessel failure, target-vessel revascularisation & procedure-related bleeding. RESULTS From 2010 to 2019, 1299 patients presented with STEMI. The cardiovascular risk factor profile did not significantly change over the 10-year study period, p = 0.23. There was a significant trend toward culprit vessel percutaneous coronary intervention with stenting, rather than balloon angioplasty followed by surgical revascularisation, p = 0.029. The mean door-to-balloon time was 88 +/- 5.7 min and demonstrated a statistically significant improvement across the decade, p = 0.035. Radial access became the preferred angiographic approach (2010 92% femoral, 2019 91% radial). Drug-eluting stents (DES) replaced bare metal stent use. There was a statistically significant reduction in 12-month cardiovascular mortality across the decade (p = 0.042). However index hospitalisation (cardiovascular and all-cause) and 12-month all-cause mortality did not reduce. Young patients and women are important sub-groups of STEMI presentations with different risk factor profile. CONCLUSIONS Advances in management of STEMI such as radial access, use of DES and a significant reduction in door-to-balloon time across the decade resulted in a reduction of 12-month cardiovascular mortality over the decade however there was no significant reduction in 12-month all-cause mortality, or index hospitalisation cardiovascular or index hospitalisation all-cause mortality. Further research is needed to ensure non-mortality outcomes, such as heart failure hospitalisation and quality of life, also demonstrate temporal improvement with STEMI management advances. Earlier cardiovascular risk assessment should be considered in smokers than is currently recommended in Australian guidelines (≥45yo for most individuals).

Abstract
OBJECTIVE Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a resource-intensive approach for the management of refractory cardiogenic shock. Within this population exists a substantial cohort of patients with peripheral artery disease (PAD), which independently increases the risk of complications and all-cause mortality. We studied 10-year national trends of the impact of PAD among VA-ECMO recipients to better understand the prevalence of PAD and implications on outcomes in this vulnerable population. METHODS This 10-year retrospective, propensity score-matched study identified all adult patients (≥18) who underwent VA-ECMO between 2009 and 2018, from a large US database (National Inpatient Sample). Patients with an ICD diagnosis of PAD were identified. The primary endpoints of in-hospital mortality, bleeding complications and major limb loss (above- or below-knee amputation) were compared between patients with PAD to those without. RESULTS A total of 6768 patients were identified, of which 342 (5.3%) had PAD. The median age at admission was significantly higher in PAD patients [64 years vs. 55 years; p < .01], as was male gender [71% vs. 64%; p < .01]. Patients with PAD had higher rates of smoking (38.9% vs. 23.3%), hypertension (71.1% vs. 50%), diabetes (37.4% vs. 27.0%), chronic kidney disease (30.1% vs. 18.0%), coronary artery disease (76.0% vs. 35.0%) and dyslipidemia (76.0% vs. 35.0); all p < .01. After propensity-matching 2:1 for comorbidities, PAD patients were found to have significantly greater overall complications, including in-hospital mortality, bleeding, surgical wound infections, pseudoaneurysms, and major adverse limb events [71.9% vs. 63.9%; p < .01]. Subgroup analysis revealed greater in-hospital mortality [62.2% vs. 55.3%; p < .05], major amputations [4.1% vs. 0.3%; p < .01] and blood transfusions [32.2% vs. 26.2%; p < .05] in PAD patients. Over 2014-2018, the non-PAD group demonstrated statistically discernable trends in a 51.1% decrease in overall complications and a 28.1% increase in survival to discharge (all p < .01). Over the same time period the PAD cohort experienced a modest, nonsignificant, decrease in complications [7.0%, p = .40] and a decrease in those surviving to discharge [47.1% vs. 40.5%, p = .91]. CONCLUSION Patients with PAD on VA-ECMO are sicker at baseline and experience significantly greater major amputations and higher in-hospital mortality. They have not benefitted from the considerable decrease in complication rates and increase in survival to discharge over time as compared to their non-PAD counterparts. These findings demonstrate the substantial frailty of the PAD population within an already high-risk cohort, and highlight the need for better procedural approaches and innovative technologies.

Current Therapeutic Approach to Acute Myocardial Infarction in Patients with Congenital Hemophilia. Life (Basel) 2021; 11:1072. [PMID: 34685443 PMCID: PMC8537181 DOI: 10.3390/life11101072] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 10/07/2021] [Accepted: 10/09/2021] [Indexed: 12/22/2022] Open
Abstract
Advances in the treatment of hemophilia have made the life expectancy of hemophiliacs similar to that of the general population. Physicians have begun to face age-related diseases not previously encountered in individuals with hemophilia. Treatment of acute myocardial infarction (AMI) is particularly challenging because the therapeutic strategies influence both the patient's thrombotic and hemorrhagic risk. As progress has been made in the treatment of AMI over the last decade, we performed an in-depth analysis of the available literature, highlighting the latest advances in the therapy of AMI in hemophiliacs. It is generally accepted that after the optimal substitution therapy has been provided, patients with hemophilia should be treated in the same way as those in the general population. New-generation stents that allow short dual antiplatelet therapy and potent P2Y12 receptor inhibitors have begun to be successfully used. At a time when specific recommendations and relevant data are scarce, our study provides up-to-date information to physicians involved in the treatment of AMI in hemophiliacs.

Abstract
Background Although ST-elevation myocardial infarction (STEMI) management has evolved substantially over the past decade, its effect on bleeding and transfusion rates are largely unknown in a contemporary population. Methods Our study cohort included patients 20 years of age or older who were hospitalized for STEMI between 2007 and 2016 across all Canadian provinces, except Quebec. Unadjusted rates of bleeding and of transfusion during STEMI episodes were calculated overall and for each province according to fiscal year. Patients were stratified into 4 groups according to their bleeding/transfusion. Characteristics, treatment, and outcomes were compared between groups. Multivariate logistic regression modelling was used to assess the association between bleeding and transfusion on in-hospital mortality. Results Using 108,832 STEMI episodes, rates of in-hospital bleeding and transfusion declined between 2007 and 2016 from 3.9% to 2.8% (P < 0.0001) and 4.7% to 3.8% (P < 0.0001), respectively. However, variation in bleeding and transfusion rates were observed across Canadian provinces. Patients with bleeding or transfusion, were older, female, and had more comorbidities. Compared with patients who did not bleed or receive a transfusion, individuals who bled, were transfused, or bled and were transfused, had higher in-hospital mortality (18.6%, 30.3%, and 30.4%, respectively [P < 0.0001]). The association remained after adjustment: bleeding (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.8-2.4), transfusion (OR, 4.4; 95% CI, 3.9-4.9), and bleeding and transfusion (OR, 3.8; 95% CI, 3.2-4.6). Conclusions The proportion of Canadian STEMI patients who experienced in-hospital bleeding and transfusion has decreased over the past 9 years. However, patients with bleed or transfusion remain at higher risk of adverse outcomes.

Cardiac mortality benefit of direct admission to percutaneous coronary intervention-capable hospital in acute myocardial infarction: Community registry-based study. Medicine (Baltimore) 2021; 100:e25058.

Abstract
ABSTRACT Appropriate risk stratification and timely revascularization of acute myocardial infarction (AMI) are available in percutaneous coronary intervention (PCI) - capable hospitals (PCHs). This study evaluated whether direct admission vs inter-hospital transfer influences cardiac mortality in patients with AMI. This study was conducted in the PCH where the patients were able to arrive within an hour. The inclusion criteria were AMI with a symptom onset time within 24 hours and having undergone PCI within 24 hours after admission. The cumulative incidence of cardiac death after percutaneous coronary intervention was evaluated in the direct admission versus inter-hospital transfer groups. Among the 3178 patients, 2165 (68.1%) were admitted via inter-hospital transfer. Patients with ST-segment elevation myocardial infarction (STEMI) in the direct admission group had a reduced symptom onset-to-balloon time (121 minutes, P < .001). With a median period of 28.4 (interquartile range, 12.0-45.6) months, the cumulative incidence of 2-year cardiac death was lower in the direct admission group (NSTEMI, 9.0% vs 11.0%, P = .136; STEMI, 9.7% vs 13.7%, P = .040; AMI, 9.3% vs 12.3%, P = .014, respectively). After the adjustment for clinical variables, inter-hospital transfer was the determinant of cardiac death (hazard ratio, 1.59; 95% confidence interval, 1.08-2.33; P = .016). Direct PCH admission should be recommended for patients with suspected AMI and could be a target for reducing cardiac mortality.

Incidence and clinical outcomes of bleeding complications and acute limb ischemia in STEMI and cardiogenic shock. Catheter Cardiovasc Interv 2020; 97:1129-1138.

Abstract
BACKGROUND Bleeding complications and acute limb ischemia (ALI) are devastating vascular complications in patients with ST-segment elevation myocardial infarction (STEMI). Cardiogenic shock (CS) can further increase this risk due to multiorgan failure. In the contemporary era, percutaneous mechanical circulatory support is commonly used for management of CS. We hypothesized that vascular complications may be an important determinant of clinical outcomes for CS due to STEMI (CS-STEMI). OBJECTIVE We evaluated 10-year national trends, resource utilization and outcomes of bleeding complications, and ALI in CS-STEMI. METHODS We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database (National Inpatient Sample) between 2005 and 2014. Events were then divided into four different groups: no MCS, with intra-aortic balloon pump, percutaneous ventricular assist device includes Impella or Tandem Heart or extracorporeal membrane oxygenation. RESULTS Bleeding complications and ALI were observed in 31,389 (18.2%) and 1,628 (0.9%) out of 172,491 admissions with CS-STEMI, respectively. Between 2005 and 2014, overall trends increased for ALI; however, the number of bleeding events decreased. ALI was associated with increased in-hospital mortality in comparison to those without any ALI. However, bleeding complications were not associated with increased in-hospital mortality. Compared to patients without complications, both bleeding and ALI were associated with increased length of stay (LOS) and hospitalization costs. CONCLUSIONS Bleeding and ALI are common complications associated with CS-STEMI in the contemporary era. Both complications are associated with increased hospital costs and LOS. These findings highlight the need to develop algorithms focused on vascular safety in CS-STEMI.

Abstract
Fibrinolytic agents including plasmin and plasminogen activators improve outcomes in acute ischemic stroke and thrombosis by recanalizing occluded vessels. In the decades since their introduction into clinical practice, several limitations of have been identified in terms of both efficacy and bleeding risk associated with these agents. Engineered nanoparticles and microparticles address some of these limitations by improving circulation time, reducing inhibition and degradation in circulation, accelerating recanalization, improving targeting to thrombotic occlusions, and reducing off-target effects; however, many particle-based approaches have only been used in preclinical studies to date. This review covers four advances in coupling fibrinolytic agents with engineered particles: (a) modifications of plasminogen activators with macromolecules, (b) encapsulation of plasminogen activators and plasmin in polymer and liposomal particles, (c) triggered release of encapsulated fibrinolytic agents and mechanical disruption of clots with ultrasound, and (d) enhancing targeting with magnetic particles and magnetic fields. Technical challenges for the translation of these approaches to the clinic are discussed.

Objective To investigate what is the most appropriate strategy for patients with ST-segment elevation myocardial infarction (STEMI) aged ≥80 years in China. Methods This cohort study retrospectively enrolled patients with STEMI aged ≥80 years old and grouped them according to the treatment strategy that was used: a conservative treatment strategy or an invasive treatment strategy. Factors associated with whether to perform an invasive intervention, in-hospital death and a good prognosis were investigated using logistic regression analyses. Results A total of 232 patients were enrolled: conservative treatment group ( n = 93) and invasive treatment group ( n = 139). Patients in the invasive treatment group had a better prognosis and lower incidence of adverse events compared with the conservative treatment group. Advanced age, creatinine level and a higher Killip class were inversely correlated with whether to perform an invasive intervention, while the use of beta-receptor-blocking agents was a favourable factor for invasive treatment. Hypertension and a higher Killip class were risk factors for in-hospital death, while the use of beta-receptor-blocking agents and diuretics decreased the risk of in-hospital death. Conclusions An invasive treatment strategy was superior to a conservative treatment strategy in patients with STEMI aged ≥80 years.

Abstract
Background Acute lung injury (ALI) is characterized by suppressed fibrinolytic activity in bronchoalveolar lavage fluid (BALF) attributed to elevated plasminogen activator inhibitor-1 (PAI-1). Restoring pulmonary fibrinolysis by delivering tissue-type plasminogen activator (tPA), urokinase plasminogen activator (uPA), and plasmin could be a promising approach. Objectives To systematically analyze the overall benefit of fibrinolytic therapy for ALI reported in preclinical studies. Methods We searched PubMed, Embase, Web of Science, and CNKI Chinese databases, and analyzed data retrieved from 22 studies for the beneficial effects of fibrinolytics on animal models of ALI. Results Both large and small animals were used with five routes for delivering tPA, uPA, and plasmin. Fibrinolytics significantly increased the fibrinolytic activity both in the plasma and BALF. Fibrin degradation products in BALF had a net increase of 408.41 ng/ml vs controls (P < 0.00001). In addition, plasma thrombin–antithrombin complexes increased 1.59 ng/ml over controls (P = 0.0001). In sharp contrast, PAI-1 level in BALF decreased 21.44 ng/ml compared with controls (P < 0.00001). Arterial oxygen tension was improved by a net increase of 15.16 mmHg, while carbon dioxide pressure was significantly reduced (11.66 mmHg, P = 0.0001 vs controls). Additionally, fibrinolytics improved lung function and alleviated inflammation response: the lung wet/dry ratio was decreased 1.49 (P < 0.0001 vs controls), lung injury score was reduced 1.83 (P < 0.00001 vs controls), and BALF neutrophils were lesser (3 × 104/ml, P < 0.00001 vs controls). The mortality decreased significantly within defined study periods (6 h to 30 days for mortality), as the risk ratio of death was 0.2-fold of controls (P = 0.0008). Conclusion We conclude that fibrinolytic therapy may be effective pharmaceutic strategy for ALI in animal models.
