Filter by:Periodontitis is an immunoinflammatory disease caused by microorganisms leading to sequential loss of the supporting structures of periodontium, resulting in periodontal pocket formation, gingival recession eventually leading to tooth loss.[1] A bacterial plaque is formed during the destructive changes of the periodontium which initiates a host of inflammatory and immune responses.[2] These inflammatory responses may also cause an increase in inflammatory activities in atherosclerotic lesions in the coronary arteries resulting in the increased risk of cardiovascular events like myocardial infarction.[3] Myocardial infarction (MI) is a cardiovascular condition that occurs when there is deprivation of oxygen in the heart muscle is due to the sudden interruption of the blood supply resulting from the coronary artery blockage by a plaque causing myocardial ischemia and cell death. Inflammation is pivotal in the initiation and progression of atherosclerosis. Various cytokines and chemokines are released during inflammation.[4] These inflammatory markers may have diagnostic potential for the detection of various inflammatory diseases.[5] Macrophages secrete macrophage inflammatory protein-1 alpha (MIP-1 alpha) which recruits inflammatory cells, inhibits stem cells, and activates bone resorption cells.[6] Interleukin-6 (IL-6) is produced in response to tissue injury and infection and contributes to the differentiation of B cells, the proliferation of T cells, and bone resorption.[7] The levels of these inflammatory markers are seen to be increased in inflammatory conditions, which include myocardial infarction and stage 4 periodontitis. Therefore, this study aims to assess the levels of these inflammatory markers in patients with myocardial infarction and periodontitis.
The delivery of timely and appropriate care is crucial for patients with heart attacks. Blocked arteries need immediate intervention to restore blood flow. However, the intervention to open the artery is only available in large, regional hospitals. There are only 18 such hospitals across Ontario. Patients with heart attacks in smaller hospitals, where the majority of patients present, require transfer for specialized services. The smartphone application being evaluated in this study is meant to help with communication between doctors to arrange transfer of such patients. The current model for communication is based on fax machines or non-secure text messages. Additionally, these are not easily accessible for most physicians, so decisions to transfer patients may be based on incomplete information. Unnecessary transfer, treatments, and procedures expose patients and healthcare providers to undue risk. Smartphone technology is well integrated into clinical practice and widely accessible. The proposed solution being tested is secure and leverages the accessibility of smartphones. Emergency physicians can use this to quickly, securely, and accurately transmit information ensuring faster and appropriate decision making for transfers.
The investigators seek to test bolus infusions (50ml/min) vs. slow infusions (20 ml/min) of Rb-82 on metrics of coronary blood flow assessed on a modern 3D PET/CT.

Background: Acute myocardial infarction (AMI) has remained a leading cause of mortality and disability worldwide. Although percutaneous coronary angioplasty (PCA) is the best treatment for these patients, paradoxically this procedure causes reperfusion injury. Considerable efforts aimed to reduce this damage have been made, but the results are disappointing and there is still no effective therapy for preventing the damage. Previously, the investigators have achieved a reduction of infarct size in an experimental model of an isolated rat heart, through a synergistic effect of three compounds in a "combined antioxidant therapy" (CAT). In this study, the investigators aim to describe the pharmacokinetics and safety of CAT intravenously administered to healthy subjects. This is the first step to a later clinical application of CAT in AMI patients. Methodology: The safety and pharmacokinetics of the CAT (deferoxamine, N-acetylcysteine, and ascorbate) will be assessed in healthy volunteers in a "phase I clinical trial". Two different formulations (mass of CAT components by bag) with different infusion rates each one will be tested (CAT1 and CAT2). Subjects (18-35 years old, n=18) will be randomized 1:2 to receive a placebo or CAT for 90 minutes. Blood concentrations of each CAT component will be measured in plasma at 0, 15, 30, 60, 90, 120, and 180 minutes after the infusion onset. Adverse events will be registered from the onset of infusion until day 30.
METHOD is a prospective observational program that will be conducted in 1centre of the Russian Federation. Prospective follow-up will be for about 6 months. The METHOD study is a 2 visit study with first visit of inclusion and second visit of completion of the study. Patients with stable angina pectoris eligible to the study inclusion criteria will be invited to participate in this observational program. The parameters for analysis will be collected by doctors and entered into CRF. The final analysis will include data from patients who were taking TMZ 80 mg OD during the observational period. The decision to stop the study will be made once 36 patients receiving treatment with trimetazidine 80 mg OD will have been evaluated at V1. It is expected that 5 cardiologists will participate in the program. The planned number of patients is 36.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been shown to improve cardiovascular outcomes when added to conventional statin therapy. This study aims to investigate the efficacy and safety of in-hospital initiation of PCSK9 inhibitor among patients with acute myocardial infarction(AMI) based on real-world experience. A total of 7556 AMI patients from the biobank database between January 2016 and December 2020 were screened for eligibility. After excluding those without revascularization or Statin based therapy, the remaining 5802 Statin users, 801 Statin plus Ezetimibe users and 170 Statin plus Evolocumab users (including 95 users without and 75 users with Ezetimibe), were selected for this study. Then, 1st and 3rd-month follow-up data were collected and analysed, including in-hospital mortality, readmission rate and lipid profiles
