| 释义 | 心肌 Patients with cardiac ischemia are at increased risk for subsequent coronary events but they may often be discharged because there is insufficient evidence to justify hospital admission. But half of the older lifelong athletes showed some heart muscle scarring. Why, Discher wondered, don't heart muscle cells then replace the scar tissue? It involves no viruses and is a foolproof method to create cardiac cells that beat, they say. The study was dubbed APOLLO, shorthand for A Randomized Clinical Trial of Adipose-Derived Stem Cells in the Treatment of Patients With ST- Elevation Myocardial Infarction. Scientists have been making cardiomyocytes from other cells for some time, usually by making induced pluripotent stem cells from some other cell, like skin cells or blood cells. For example, in the cases of the heart- muscle cells and pancreatic cells mentioned above, dosing them with leptin keeps them healthy. Mark's enlarged heart was failing to pump blood adequately. Last week, Europe banned Avandia because of the concern about the risk of myocardial infarction and other cardiovascular risk. All patients had a negative cardiac troponin I cTn- I result at presentation and cTn-I was used as the outcome measure. He has managed to reprogram mouse connective-tissue cells so that they develop into cardiac muscle cells, and has tested them in the hearts of mice that have had heart attacks. They hope their work could also lead to a new way to make artificial liver or cardiac tissue. All had suffered a type of heart attack known as an ST segment elevation myocardial infarction, caused by a prolonged period of blocked blood supply. It's made up of a special kind of muscle cardiac muscle that works involuntarily, so we don't have to think about it. Twenty-five per cent of my heart muscle died. We've done years of work in showing that excess alarm or stress chemicals can literally burst heart muscle fibers. Chronic inflammation of tissues in the circulatory system is a risk factor for cardiovascular disease, such as myocardial infarction or stroke. IMA has been evaluated as a potential indicator of transient myocardial ischemia in different clinical models of myocardial injury. During a10- year follow-up,82 women had a heart attack or myocardial infarction and112 had a stroke. Short sleep duration was associated with angina, while both sleeping too little and sleeping too much were associated with heart attack and stroke, the study says. This diagnostic target is still in its infancy and there is no“ gold standard” for accurately assessing myocardial ischemia. Electrical impulses in the myocardium, the heart's muscular wall, keep your heart beating. |
