Active clinical trials for "Myocardial Infarction"

This study compares patients bound for Percutaneous Coronary Intervention (PCI) who were transported by either ground ambulance or emergency medical helicopter. The investigators describe long-term follow-up in relation to mortality and labour affiliation.

The intent of this study is to determine the difference in pharyngeal oxygen concentration in patients who have a natural airway (not intubated) using commonly available oxygen delivery systems. The investigators will test the hypothesis that oxygen concentration during the period of inspiration (FiO2) in the pharynx is dependent on oxygen delivery system design, even at high flow (15 liters/minute) oxygen delivery. Specific measurements include oxygen concentration at subjects' lips and pharynx when breathing 100% oxygen and room air via a simple mask, non-rebreather mask, OxyMaskTM, and anesthesia mask with headstrap and Jacson Rees circuit. A mean difference of 10% pharyngeal FiO2 between any of the masks will be considered clinically important. The expected standard deviation of the within-subject FiO2 is 3.5%. With a significance criterion of 0.05, 10 subjects would provide more than 90% power to detect a mean difference of 10%.

Quasi-experimental, controlled interrupted time series design, evaluating the impact of the intervention at Hamilton Health Sciences (HHS) where standardized prescriptions and education will be provided and St Joseph's Hospital (SJH) and Niagara Health Services (NHS) where education alone will be provided, with remaining Ontario cardiac sites as a concurrent control group.

To evaluate the effect of automated recording on frequency of recorded scores, number of automated notifications and serious events.

GLP-1(9-36) amide and (9-37), which was previously thought to be the inactive metabolite of GLP-1, also exerts cardioprotective effects. Direct administration of GLP-1(9-36) during reperfusion reduced ischaemic damage in isolated hearts and increased cGMP release, vasodilatation and coronary flow in AMI mouse model, one may speculate that total GLP-1 level may associate with adverse cardiovascular events in AMI patients, the hypothesis is therefore tested in this study.

The proposed study is a pilot randomized clinical trial (RCT). Participants in the intervention arm will participate in a 90-day adherence promotion program based on the theory of behavioral economics and administered through the Wellth mobile phone application. Subjects will be provided a CleverCap® Lite BLE C035 smart pill bottle (electronic monitoring (EM), device) containing a 90-day supply of aspirin (90 pills) and those in the intervention arm will be offered $150 for app-based medication check-ins, which consist of uploading daily photos of pills at the time of administration through the Wellth app. Subjects will have $2 deducted from total rewards for each day that a medication check-in is missed. Subjects in the control arm will receive usual care and be monitored with the same EM device types used in the intervention arm.

This was a prospective randomized, controlled trial designed to quantify the reduction in cost and length of stay of early discharge of emergency department patients evaluated for acute myocardial infarction, who are deemed to be low risk based on a modified HEART score (a score that incorporates troponin biomarker, ecg, patient characteristics, and physician clinical judgment).

Besides contrast-induced acute kidney injury (CI-AKI), adscititious vital organ damage such as hypoxic liver injury (HLI) may affect the survival in patients with ST-elevation myocardial infarction (STEMI). Therefore, the investigator sought to evaluate the prognostic impact of CI-AKI and HLI in STEMI patients who underwent primary percutaneous coronary intervention (PCI).

The HIV/HEART study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to May 2014 (7,5 year Follow-up) 1481 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.

This study evaluates the use of early mechanical circulatory support in patients presenting with acute myocardial infarction and cardiogenic shock. Patients are treated according to the National Cardiogenic Shock Initiative protocol, which emphasizes early identification of cardiogenic shock and rapid delivery of mechanical circulatory support based on invasive hemodynamics. All patients treated in this manner are enrolled in the National Cardiogenic Shock registry.
