Filter by:Following acute cardiovascular injury, inflammation is vital to activate reparative mechanisms. However, there is compelling evidence implicating excessive inflammation and dysregulated resolution in fibrosis, ventricular remodelling, and heart failure (HF). Recently, the anti-inflammatory agent colchicine reduced cardiovascular events after myocardial infarction (MI) compared to placebo, indicating that targeting inflammation in acute cardiovascular conditions is feasible. Several acute cardiovascular conditions are characterised by inflammation, including myocarditis, MI, and acute heart failure. However, there is large variability in definition, epidemiology, clinical presentation, pathophysiology, and natural history of acute inflammatory cardiovascular diseases. This relates, in part, to the difficulty in performing adequately powered studies. Clinical studies that include sufficient patients and extended observation periods are necessary to address some of these knowledge gaps. This registry aims to collate routinely collected clinical data on patients with acute cardiovascular diseases characterised by inflammation in an observational-based registry. By doing so, the investigators hope to understand the contribution of inflammation to the pathophysiology of acute cardiovascular disease, improve risk stratification, and identify potential novel therapeutic targets.
This is a single-center retrospective observational study in which we consecutively selected patients diagnosed with acute myocardial infarction from September 2019 to March 2024 at the Affiliated Hospital of Xuzhou Medical University. Inclusion criteria: 1. CMR was completed during all hospitalizations; 2. complete clinical data; 3. received continuous cardiac monitoring during hospitalization. Exclusion criteria: 1. unclear or non-compliant CMR images; 2. previous history of myocardial infarction; 3. malignant tumors diseases. Dedicated cardiovascular imaging software CVI42 (cvi42® version 5.13.5, Circle Cardiovascular Imaging, Canada) was used for image analysis. LA strain was obtained by cardiac MRI feature tracking. Patient prognosis was obtained through chart notes and telephone follow-up. Major events included atrial fibrillation, ischemic stroke, and all-cause mortality.
Previous research has confirmed that patients undergoing percutaneous coronary intervention (PCI) can benefit from cardiac rehabilitation programs. However, there is a paucity of studies on Phase I cardiac rehabilitation commenced within three days following PCI in patients with acute myocardial infarction (AMI). Consequently, the objective of the study is to demonstrate whether Phase I cardiac rehabilitation can improve the prognosis at 12 months when compared with the control group. The primary endpoint is the Seattle Angina Questionnaire (SAQ) score at 12 months for the patients. The principal hypothesis of the study is that Phase I cardiac rehabilitation will improve the long-term prognosis for AMI patients at 12 months after PCI.
The purpose of this study is to utilize an innovative healthcare delivery strategy via telehealth group counseling sessions to improve engagement, adherence, and ultimately outcomes in female patients with atherosclerotic cardiovascular disease (ASCVD).
Because treatment decisions are usually based on a single measurement of the lipid panel at the time of an admission for an MI, the overarching objective of this project is to evaluate whether the measurement of LDL, non-HDL, and apoB values are reliable through all the duration of the hospitalization. It will be a single-center, prospective, observational study will be conducted, including consecutive patients hospitalized for myocardial infarction at the Montreal Heart Institute. Every patient at the Cardiac Care Unit will undergo non-fasting lipid panel testing at day 0 of their admission for Myocardial Infarction during the study period. Patients who consent to participate will have a 2nd non-fasting lipid panel drawn at day 2 of their admission. Thereafter, the levels of the different lipid values from the panel will be compared between day 0, day 2, and 4-6 weeks after discharge.
The aim of the study was to intervene in the Aerobic exercise time of patients with STEMI and to explore the optimal exercise time for STEMI patients
The goal of this observational study is to find out if artificial intelligence (AI) can accurately predict acute coronary syndrome (ACS) using data on white blood cells in adults. The main question it aims to answer is: - Can AI algorithms based on white blood cell data predict ACS with accuracy comparable to that of high-sensitivity cardiac troponin (hs-cTn)? Researchers will look at how the AI model's predictions stack up against the standard hs-cTn blood tests to see which is more accurate in diagnosing ACS. Participants in this study will have already had blood tests as part of their usual care. Their previously collected health information and blood test results will be used to help train and test the AI algorithms. Participants will not undergo any new procedures for the study itself.
Study rationale: to evaluate clinical and prognostic relevance of microvascular dysfunction, coronary flow reserve and cardioprotective effects of iv administration of esmolol in patients with myocardial infarction. First substudy is an open randomized trial evaluating the efficacy and safety of early intravenous administration of esmolol in patients with acute ST-segment elevation myocardial infarction (MI) and relative contraindications to administration of other intravenous β1-adrenergic blocker (metoprolol etс.). Сomparison group will include patients who have not received intravenous β1-adrenergic blocker. Secondary outcome in this substudy is the degree of microvascular obstruction and infarct size according to MRI with gadolinium delayed enhancement. Second substudy examines the quantitative parameters of coronary physiology in patients with MI and multivessel disease. Changes of coronary physiology measurements over time ((iFR, Pd/Pa, FFR, delta FFR, gradient FFR per time unit (dFFR(t)/dt), pullback pressure gradient (PPG)) measured in the infarct-related artery and in non-infarct-related arteries with diameter stenosis of 50-85% immediately after the completion of a primary percutaneous coronary intervention and during a second hospitalization (30-45 days after STEMI) will be evaluated. The comparison changes of coronary physiology over time with presence of an MVO and infarct size determined by MRI. The model of calculating coronary flow reserve (CFR) based on tridimensional reconstruction of coronary arteries and coronary physiology parameters as measured during coronary angiography will be developed. The influence of coronary physiology parameters measured after complete myocardial revascularization by PCI, and derived CFR in patients with MI on long-term clinical outcomes will be evaluated, based on prospective data collection. Primary composite outcome in all substudies will be the sum of adverse cardiac outcomes (congestive heart failure, episodes of recurrent congestive heart failure worsening resulting in hospitalizations, cardiac mortality, MI recurrences, unstable angina, urgent myocardial revascularization) within > 12 months post-infarction. Secondary composite outcome in all substudies is the degree of microvascular obstruction and infarct size evaluated by MRI with gadolinium delayed enhancement.
A pilot study confirmed the feasibility and safety of neuroprotectant Y-3 intracalvariosseous(ICO) injection in patients with malignant middle cerebral artery infarction (mMCAI), showing a trend in improving 90-day functional scores compared to conventional treatment. The aim of this trial is to further investigate the efficacy and safety of ICO injection of Y-3 compared to intravenous injection in patients with acute large hemispheric infarction(LHI) who has contraindications of reperfusion therapy or have got poor reperfusion therapy outcomes.
This study is to evaluate the effect of Inclisiran on coronary atherosclerosis using intravascular ultrasound (IVUS) and optical coherence tomography (OCT) in patients with acute myocardial infarction and elevated low-density lipoprotein cholesterol (LDL-C).
