Filter by: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.
This study aims to investigate the association between active transport and the incidence of acute myocardial infarction in England.
This project aims to evaluate, in recent post-acute myocardial infarction (AMI) patients on dual antiplatelet therapy, the impact of regular exercise training on platelet aggregability and the correlation between the level of platelet aggregability and muscle sympathetic nerve activity (MSNA).
The aim of this study was to estimate the impact of sex on relative survival and excess mortality following acute myocardial infarction (AMI) using a population-based cohort within a relative survival framework. Patient-level data concerning demographics, co-morbidity, cardiovascular risk factors and treatments at discharge were extracted from the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART), a population-based registry of outcomes for patients hospitalized with acute coronary syndrome. Patients were followed-up for their vital status after AMI hospitalisation, with censoring at the end of follow-up on the 31st of December, 2013.
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.
The goal of this study is to use three (3) different imaging techniques:Fractional Flow Reserve (FFR) allows precise measurement of blood flow in the arteries to the heart, and is more reliable than pictures alone to determine the significance of blockages in the heart; Near Infra-Red Spectroscopy-Intravascular Ultrasound (NIRS IVUS) provides information about the amount of lipid and cholesterol in the plaque, and plaque volume; and Optical Coherence Tomography (OCT) allows physicians to assess tears in the surface of plaque and plaque thickness; to evaluate high risk non-infarct-related coronary lesion in patients who have suffered a recent heart attack, underwent successful opening of the artery with a stent, and have blockages greater than or equal to 50% in one or more of the other arteries to the heart; and to correlate this findings with cardiovascular outcomes at 1 year.
The purpose of this study is to evaluate the efficacy and safety of LCZ696 titrated to a target dose of 200 mg twice daily, compared to ramipril titrated to a target dose of 5 mg twice daily.
Changes in the ambient temperature (esp. warm to cold) as well as exercise are triggers for vasospasms and plaque rupture. Weather data (temperature, precipitation in general as well as snowfall and changes in atmospheric pressure) will be correlated with the incidence of myocardial infarctions.
This study evaluates the relationship of change of dendritic cells fractalkine and P-selectin in patients with acute myocardial infarction.
Besides classical cardiovascular risk factors such as smoking, obesity, elevated cholesterol levels and diabetes there are also acute factors potentially triggering acute coronary events. The impact of various substances and air pollution are described. Particulate matter, especially with small particle size (<2.5µm) has been shown to have a positive correlation with myocardial infarctions. However, other studies failed to show this correlation. With respect to nitric oxydes the majority of published studies detected a significant correlation with myocardial infarction, too, although a highly ranked publication failed to show the same result. In addition data on the impact of sulfur dioxide and carbon monoxide concentration on cardiac events is very heterogeneous. Published data indicates additive effects of age and other epidemiological variables suggesting the need of a multivariate analysis. The rationale of the study is to test if the above mentioned air pollution factors have a significant and independent impact on the incidence of myocardial infarctions
