Active clinical trials for "Infarction"

During primary percutaneous coronary intervention, distal embolization of thrombus and impaired microvascular perfusion has been associated with an increased mortality. Thrombectomy devices during primary percutaneous coronary intervention may prevent distal embolization by reducing thrombus burden and thus improve microvascular perfusion and reduce mortality.

Acute MR may develop in the setting of an acute myocardial infarction (AMI) as a result of papillary muscle dysfunction or rupture, and these patients are grossly underrepresented in MitraClip registries. Our group has recently published the Spanish experience with MitraClip in acute MI, but only 5 patients could be collected. However, the results of our initial experience are highly encouraging since patients performed well in such life-threatening condition. In order to expand the information of the device in this condition, our aim is to start a multinational registry in Europe.

Is the Smartphone ECG (electrocardiogram) an acceptable replacement for a standard ECG in the identification of STEMI (ST Elevation Myocardial Infarction).

This study aims to determine the extent to which pre-existing long-term conditions are associated with survival following a heart attack (acute myocardial infarction) using observational data from the UK's national heart attack register.

Increased plasma DPP4 activity (DPP4a) could predict both subclinical and new-onset atherosclerosis, and our previous study has found that the DPP4a was significantly lower in MI patients compared with patients having chest pain or unstable angina alone, and DPP4a is associated with no-reflow and major bleeding events in STEMI patients during hospital stay. As no-reflow phenomenon and major bleeding events independently associates with a worse in-hospital and long-term prognosis. One may speculate that the DPP4a is associated with long-term follow-up adverse cardiovascular events in these patients.The hypothesis was tested in this study.

Currently when defining the upper limit of normal (ULN) or 99th percentile of a troponin assay manufacturer's use a healthy population traditionally aged 18-40. The 99th percentile value is the recommended value to use when diagnosing patients with an acute myocardial infarction. With the advent of the new highly sensitive troponin assays it has become clear that many patients have a troponin level above the 99th percentile when they have not suffered a myocardial infarction. We believe part of the problem with interpreting the the troponin values for patients is that the 99th percentile value which determines the ULN has been derived from population that is very different to the hospital population of patients. This study aims to demonstrate what the 99th percentile is for the population of people who use the hospital services who are traditionally older and have more comorbidities when compared to the population traditionally used to define the 99th percentile of a troponin assay. An amendment was approved to follow-up patients' clinical outcomes at 1 year using NHS Digital data.

Methods: All patients <75 years registered in the Swedish Secondary Prevention after Heart Intensive care Admission registry (SEPHIA), will be followed-up within one year post-myocardia infarction (MI). The REACH risk prediction and a calibrated model for recurrent cardiovascular disease (CVD) events and death will be used to estimate base case, and calibrated CVD outcomes based on gender-specific risk factors. The predicted impact of the LDL-C reduction on the risk of CVD will be based on Cholesterol Treatment Trialists´ Collaboration findings.

Cardiovascular diseases, and more precisely patients with ST - elevated myocardial infarction are globally responsible for a large number of hospitalizations and deaths. Monitoring the quality of care for these patients is very relevant topic. Investigators developed indicators from the scientific literature on the quality of care for patients with STEMI at both the patient level and hospital level. The indicators were subsequently validated by a RAND modified Delphi - study of multidisciplinary experts in the care of patients with STEMI. In this study, the following objectives are set: ) Study of the quality of care for patients with STEMI in 16 Flemish hospitals with cardiology department by retrospective and prospective audit of 20 patient records per participating hospital . ) Study of the interdisciplinary relationships and communication within teams involved in the care of patients with STEMI in the participating hospitals 3) Study of perceived organization of care for patients with STEMI in the participating hospitals In accordance with the objectives of the research, the study consists of three phases: ) A retrospective observational audit of 20 patient records of patients with STEMI each participating hospital. ) A prospective observational audit of 20 patient records of patients with STEMI each participating hospital. ) A survey using validated instruments of interdisciplinary relationships and communication on the one hand and on the other by the teams involved in the care of patients with STEMI perceived organization of care . Data collection is performed by local researchers and remains their property. The data is coded and kept confidential. Only the local researcher has access to the encryption key. The data are protected by the Belgian law on privacy and medical confidentiality, only to be used in the context of this study. The results are published anonymously.

The Myocardial Infarction Register Saarland (MIR-SL), is intended to collect data about the treatment of patients suffering from ST-elevation myocardial infarction (STEMI). It aims to provide current data on the implementation of guidelines for both, the interventional and adjuvant drug therapy of STEMI in daily clinical practice in the Saarland.

In the FINE 75+ study, 307 Non ST Elevation Myocardial Infarction (NSTEMI) patients, 75 years old or older, were included between September 2009 and June 2010. The purpose of this observational study (FINE75+5) is to describe these patients, especially regarding the following variables: cardiovascular risk, co-morbidity and frailty, and to assess the prognostic value of frailty on 5-year outcomes. We hypothesize that frailty is independently associated with 5-year mortality.
