Background: Post-acute myocardial infarction (post-AMI) infection is an infrequent but important and serious complication in patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI). Predicting its occurrence is essential for future prevention. However, little is known about the prediction of post-AMI infection in such patients to date. This study aims to develop and validate a new risk score based on risk factors for early prediction of infection in STEMI patients undergoing PCI.Methods: This prospective, multi-center and observational study assesses the predictive value of risk score for post-AMI infection among a cohort of patients hospitalized due to STEMI. The STEMI patients undergoing PCI enrolled between January 1st 2010 and May 31st 2016 were served as a development cohort while those enrolled from June 1st 2016 to May 31st 2018 were served as validation cohort. The primary endpoint was post-AMI infection during hospitalization, defined as infection requiring antibiotics (reflecting the clinical influence of infection compatible with the necessity for additional treatment), and all-cause death and major adverse cardiovascular events (MACE) including all-cause death, recurrent myocardial infarction, target vessel revascularization, and stroke were considered as secondary endpoints. The risk score model based on risk factors was established using stepwise logistic regression, and will be validated in other centers and external patients with non-ST-elevation acute coronary syndrome (NSTE-ACS).Results: This study will provide evidence on prognostic property, reliability of scoring, comparative performance, and suitability of the novel model for screening purpose in order to be recommended for clinical practice.Discussion: Our study is designed to develop and validate a clinical risk score for predicting infection in participants with STEMI who have undergone PCI. This simple tool may therefore improve evaluation of post-AMI infection and enhance future researches into the best practices to prevent or reduce infection in such patients.Clinical Trial Registration:www.chictr.org.cn, identifier: ChiCTR1900028278.

IntroductionDelirium in the postoperative period is a wide-reaching problem that affects important clinical outcomes. The incidence and risk factors of delirium in individuals with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PCI) has not been completely determined and no relevant systematic review and meta-analysis of incidence or risk factors exists. Hence, we aim to conduct a systematic review and meta-analysis to ascertain the incidence and risk factors of delirium among AMI patients undergoing PCI.Methods and analysesWe will undertake a comprehensive literature search among PubMed, EMBASE, Cochrane Library, PsycINFO, CINAHL and Google Scholar from their inception to the search date. Prospective cohort and cross-sectional studies that described the incidence or at least one risk factor of delirium will be eligible for inclusion. The primary outcome will be the incidence of postoperative delirium. The quality of included studies will be assessed using a risk of bias tool for prevalence studies and the Cochrane guidelines. Heterogeneity of the estimates across studies will be assessed. Incidence and risk factors associated with delirium will be extracted. Incidence data will be pooled. Each risk factor reported in the included studies will be recorded together with its statistical significance; narrative and meta-analytical approaches will be employed. The systematic review and meta-analysis will be presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationThis proposed systematic review and meta-analysis is based on published data, and thus there is no requirement for ethics approval. The study will provide an up to date and accurate incidence and risk factors of delirium after PCI among patients with AMI, which is necessary for future research in this area. The findings of this study will be disseminated through publication in a peer-reviewed journal.PROSPERO registration numberCRD42020184388.

OBJECTIVES To determine clinical outcome and to nd out the association between participation of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) in cardiac rehabilitation programme. DESIGN A Prospective observational study. STUDY AREA : Department of Cardiology, Institute of Postgraduate Medical Education and Research,Kolkata. PARTICIPANTS: Patients aged ≥18 years who underwent PCI due to AMI. OUTCOME MEASURES The outcomes were subsequent myocardial infarction, revascularisation, all-cause readmission, cardiac readmission, all-cause mortality and cardiac mortality. RESULT: The data of 1107 patients were included and 60.07%% of them participated in CR program. The risks of revascularisation, all cause readmission and cardiac readmission among CR participants were compared. The results of those analysis were consistent and showed that the CR participants had lower allcause mortality ,cardiac mortality,all cause readmission, cardiac admission. However no effect was observed for subsequent myocardial infarction or revascularisation. CONCLUSIONS: It was suggested CR participation may reduce the risk of all-cause mortality ,cardiac mortality, all cause readmission and cardiac admission.

Introduction and Objective. In Mexico, there has been an increase in the risk of cardiovascular disease due to rising life expectancy, westernized lifestyle, lack of prevention, and industrialized exposure. This article describes the pharmacological treatment, surgical interventions, and associated clinical complications in patients diagnosed with acute coronary syndrome (ACS) and their impact on in-hospital mortality frequency in a Cardiology Unit in Instituto Mexicano del Seguro Social. Methods. This is a retrospective study including male and female patients aged ≥18 years who were diagnosed with ACS. The collected data included demographic characteristics, risk factors, medications, electrocardiograms, surgical procedures, and in-hospital deaths. Results. There are at least 20% more diagnoses of ST-segment elevation myocardial infarction in this hospital compared to the latest national reports in Mexico. The most common risk factors were type 2 diabetes mellitus, hypertension, smoking, and dyslipidaemia. Diabetic patients with a clinical history of percutaneous coronary intervention had a higher risk of non-ST-segment elevation myocardial infarction than nondiabetics (OR: 2.34; p=0.013), also smoking patients with previous heart surgery than nonsmokers (OR: 7.73; p=0.0007). The average in-hospital mortality was 3.6% for ACS. Conclusions. There is a higher percentage of coronary interventionism and improvement in pharmacological treatment, which is reflected in lower mortality. The substantial burden of T2DM could be related to a higher number of cases of STEMI. Diabetics with precedent percutaneous coronary intervention and smokers with previous heart surgery have an increased risk of subsequent infarction.

Aim: to study the risk factors, clinical peculiarities, diagnosis and treatment of young patients with myocardial infarction (≤ 44 years).Material and methods. The research included 189 patients, who had MI in the period from January 1, 2015 to December 31, 2019 at the age of ≤ 44; 92.1% of patients were men. The average age of all patients was 41,2 (37.3; 43.6).Results. Most frequent risk factors for the development of MI were: smoking — in 77.8%, essential hypertension — in 73.5%, burdened inheritance — in 49.2%, obesity — in 39.7% and pancreatic diabetes — in 10.6% of all cases. ST segment elevation was registered on the electrocardiogram in 87,8% of patients; 4.2% of them had only thrombolytic therapy; thrombolytic therapy was followed by coronarography with the intention of performing percutaneous coronary intervention (PCI) in 30.7% of cases; coronarography with the intention of performing primary PCI was applied to 54.2% of patients. PCI was performed in 76.5% of patients. 12.2% of patients had acute coronary syndrome without ST-segment elevation, and 95.7% of them had coronarography with the intention of performing percutaneous coronary intervention. PCI was performed in 73.9% of patients. Assignment frequency of beta-adrenergic blocking agent prescription was 95,2% (178 out of 187), аngiotensin-convertingenzyme inhibitors and sartans — 95.2% (178 out of 187), statins — 99.5% (188 of 189), dual antiplatelet therapy — 99.5% (188 out of 189), mineral corticoid receptor antagonists with ejection fraction of left ventricle of heart ≤ 40% — 28.6% (2 of 7).Conclusion. The conducted research aims at the discussion of the vital topic of young patients with myocardial infarction management. It focuses on risk factors, clinical and angiographic presentation, and secondary prevention.
