Active clinical trials for "Myocardial Infarction"

The investigators will conduct a feasibility study of an enhanced transitional care intervention, that will: 1) automate identification and risk-stratification of patients with CHF and IHD with social vulnerabilities; 2) incorporate a new standardized social vulnerabilities screening tool into clinical care; 3) enable electronic referrals to community resources; and 4) add novel community-based interventions to the existing medically-oriented transitional care intervention that is the standard of care at the study hospital (Parkland Hospital in Dallas, Texas) and other hospitals nationwide.

Background: Initially conceived of as a method to address healthcare needs of underserved rural populations, Mobile Integrated Healthcare and Community Paramedicine (MIH/CP) is a new model of inter-professional, community-based outpatient healthcare delivery that primarily utilizes the resources and training of Emergency Medical Services (EMS) to fill gaps in local healthcare infrastructure, expanding existing scope of practice in most cases while not detracting from acute transport capabilities. Although programs have been in existence since the early 1990s, there are few objective studies of the efficacy, safety, and cost-effectiveness of MIH/CP programs, many of which are limited-scope pilot projects. The limited data already published on these measures by established programs shows substantial Medicare charge-avoidances in patients enrolled in CHF-readmission prevention and EMS frequent user programs, and a significant reduction in Emergency Department visits overall, especially in austere environments. In summary, MIH/CP is an attempt at formalization of long-standing practices to collaborate with and supplement other healthcare system components such as primary care and home health services. Standardized, objective data collection and publication of results will be needed to support continuation and financial support of this emerging concept. Objective/Hypothesis: Using the existing resources of the MD-, RN- and Paramedic-staffed Lifespan Pediatric and Adult Critical Care Transport (LifePACT) service, investigators aim to study whether implementation of an MIH/CP pilot program tailored to the needs of an urban, underserved population in Providence, Rhode Island, will reduce the rate of 30-day hospital readmissions for patients after discharges for community-acquired pneumonia, acute MI, and COPD. In addition, investigators will study whether such a program is considered to be safe (in terms of not increasing the number of adverse events post-discharge for patients or compromising the efficacy of the LifePACT transport role) and considered satisfactory by patients (rated comparably to visits by other outpatient health care services such as VNA services).

one-centered, open, prospective, non-randomized, controlled clinical study will be aimed at creating remote monitoring system for patients' condition and the development of methodological approaches and its usage for conducting patients, who had myocardial infraction and who has a very high risk of developing an unfavorable outcome.

FAST and Stroke-112 are two campaigns to reduce the emergency room arrival time of stroke patients. No study has evaluated the effectiveness of these campaigns. This study aimed to compare recalling capacity of people in these two campaigns.

This prospective trial will include 150 patients with myocardial infarction with non-obstructive coronary arteries (MINOCA). A thorough clinical, laboratory and imaging evaluation will be performed by novel biomarkers and modern imaging techniques (heart magnetic resonance imaging and noninvasive testing). Moreover, two different treatment groups will be distinguished. Additionally, a retrospective analysis of patients meeting MINOCA criteria will be performed.

Background: Unfractionated heparin (UFH) is a sulfated polysaccharide extracted from porcine intestinal mucosa that enhances the inhibitory activity of the natural anticoagulant antithrombin towards most activated clotting factors (F), particularly FXa and FIIa (thrombin) . Despite the growing interest for low molecular weight derivatives (LMWH), UFH is still widely used for different indications including the treatment of acute thrombosis including venous thromboembolism, coronary syndromes (ACS), and other thrombotic diseases. UFH is administered by parenteral route either intravenous (IV) or sub-cutaneous (SC).Actually, there is evidence that the risk of recurrence of thrombosis is increased when heparin levels fells below the lower limit of the therapeutic range, while the hemorrhagic risk increases with heparin levels above the upper limit of the therapeutic range. Moreover, the anticoagulant response to UFH is highly variable for one individual to another. As the clinical efficacy of heparin is dependent on maintaining an anticoagulant effect above a minimum level, careful laboratory monitoring of UFH treatment is mandatory. For that purpose, two options are offered to the clinicians: i) to evaluate either the prolongation of a global clotting assay, the activated partial thromboplastin time (aPTT) and ii) to measure the heparin-enhanced inhibitory activity of AT toward purified activated factors such as FIIa and FXa using chromogenic substrate-based assays. UFH therapy is still widely monitored by the aPTT, a global clotting assay, that reflects the ability of heparin to enhance the inhibitory activity of AT against FIIa, FXa, and other activated factors. The therapeutic range of aPTT prolongation is highly dependent on the reagent and analyzer used. As the consequence, it must be defined by each laboratory in its own technical conditions (for each reagent batch) to correlate with heparin levels between 0.20 and 0.40 U/mL (protamine sulfate titration), corresponding to anti-FXa activity between 0.30 and 0.70 IU/mL. In that connection, the prolongation of aPTT corresponding to antiFXa activity between 0.30 - 0.70 IU/mL is highly variable depending of the reagents e.g.between 1.6 - 2.7 x control for weakly sensitive reagents and between 3.7 - 6.2 x control for highly sensitive reagents. The use of aPTT has advantages as it is easy-to-perform, quick, inexpensive but faces numerous challenges due to the significant influence of the technical conditions (reagent/instrument) on the test result, to lot-lot variation in reagent sensitivity, to the need of studies to evaluate the therapeutic range, to limited therapeutic range, and also to non-specific prolongation in the case of lupus anticoagulant, factors deficiency, inhibitors or shortening in the case of high factor levels, particularly FVIII.In contrast, the use of chromogenic anti-Xa assays has many advantages particularly a published therapeutic range for UFH i.e. between 0.30 and 0.70 IU/mL, a specificity to its interaction with AT (no Heparin Cofactor II interference by using bovine FIIa or short incubation time) and faces few challenges such as limited availability in some area and a cost that is slightly higher than that of aPTT. In addition, anti-Xa assays allow accurate measurement of all heparin(s) derivatives and particularly LMWHs and fondaparinux. Since the first reports in the mid-eighties, some small sized studies have compared the two monitoring strategies mainly retrospectively designed (7-11). Even though, one single prospective randomized management study evaluated the comparison between the two monitoring strategies with clinical end-points i.e. recurrence of thrombosis and bleeding complication in a cohort of 131 patients with VTE . All concluded to a trend toward higher, or at least similar, safety/efficacy/efficiency when patients were monitored using antiXa activity vs. aPTT. Even though differences were not significant due to the lack of power of these studies.

Ischemic heart disease is the leading cause of mortality with 7.2 million of death in industrialized countries (WHO data). Myocardial infarction corresponding to acute occlusion of a coronary artery is the most brutal form and the more severe ischemic myocardial disease. Every year in France, about 60,000 Myocardial infarctions hospitalized, 30,000 are diagnosed remotely and 30,000 are revealed by an inaugural sudden death. Although mortality from myocardial decreased by 30% over the past decade, the prognosis is pejorative and difficult to assess precisely. The management of the patient depends on these factors, and justifies an active search on these topics, including the mechanisms of the deleterious ventricular remodeling, myocardial inflammation, reperfusion injury which determines in particular the evolution to heart failure. Cohorts of patients with myocardial infarction are rare but can be very valuable by their clinical, laboratory and imaging well documented. They are the source of new hypotheses for research or interventions as well as the quality of care assessment tool. The main objective of this project is to identify new markers: biological and imaging, treatment response and prognosis after acute myocardial infarction. Secondary objectives of the HIBISCUS-STEMI cohort to establish a clinical database, completed by biological samples and by imaging data that can be used in the following areas: Descriptive epidemiology of myocardial infarction and myocardial reperfusion Pharmacoepidemiology and treatments observatory: safety, efficacy, indication of treatment in real life, costs Assessment of the long-term effect of the treatment on the occurrence of heart failure and sudden death Quality of life and personal consequences, family, professional and social myocardial infarction Research of new diagnostic and prognostic biomarkers Research projects (e.g. risk of developing kidney failure or stroke in patients with myocardial infarction compared to the general population).

In this study the investigators aim at comparing the effect on quality of life and the cost-effectiveness of a structuralised sick-leave program compared to usual care sick leave management in patients after an acute non ST myocardial infarction(NSTEMI).The investigators hypothesize that a structuralised sick-leave program after an acute NSTEMI is cost-effective without a negative effect on quality of life compared to usual care management in this patient group.

A randomized controlled trial using seated Tai Chi (TC) as a rehabilitation intervention will be conducted among subacute stroke survivors. It aims to evaluate the effects of seated TC on recovery outcomes among subacute stroke survivors. Stroke survivors and their unpaid caregivers will be recruited as dyads participants. A number of 160 dyads will be recruited from a neurology department of a Tertiary A level provincial Traditional Chinese Medicine hospital in Mainland China with around 1700 beds. The study will be conducted in hospital and homes. The participants will be randomly assigned to the seated TC group or the usual exercise group. The study will last for 12 weeks (two-week training in hospital and 10-week self-practice at home) and 4-week followup. Stroke survivors in the seated TC group will participate a TC master-led, 30-minute seated TC exercise per day, five days per week for two weeks. When they discharge, they will perform the seated TC at home for 10 weeks. Those in the usual exercise group will receive usual exercise which has the same frequency and duration as the seated TC group. They will also perform self-practices at home for 10 weeks. Family caregivers will be encouraged to support the exercise intervention and help with recording the logbook of self-practice at home. Manual and training videos recorded by the same master will be given to the dyads of both groups to facilitate their continuation of self-practice on the day they discharge through WeChat. Biweekly reminder will be sent to the family caregivers by the PI through WeChat during the self-practice and follow-up period. The stroke survivors' upper limb function, balance control, depressive symptoms, activity of daily living, and quality of life will be measured at the following time point: baseline, after the supervised intervention (two weeks), eight weeks, after self-practice intervention (12 weeks) and at the end of follow-up (16 weeks). If the study finds significant effects on recovery among subacute stroke survivors, nursing professionals can act as care coordinators/ advocators to incorporate this culture-based exercise in stroke survivors' rehabilitation programs. Seated TC can be used as a clinically feasible exercise for nurses to work with other healthcare professionals for the promotion and application of evidence-based complementary and alternative therapy in promoting stroke survivors' recovery.

Aim. To develop and examine the effectiveness of an APN-led telehealth rehabilitative programme as a transitional nursing therapeutic on readmission rates and health related outcomes amongst patients with Acute Myocardial Infarction (AMI) post discharge. Design. Randomized controlled trial with repeated measures. Methodology. A consecutive sampling of 172 patients with AMI will be recruited from a tertiary hospital in Singapore. Participants will be randomised into two groups. The experimental group (ALTRA) will receive APN-led telehealth rehabilitative programme upon discharge in addition to standard care. The control group will receive only standard follow-up care.
