Severe breathing disorders during sleep are associated with an increased risk of dying from any cause according to research published this week in the open access journal PLoS Medicine. The study finds that the increased risk of dying is most apparent in men between 40 and 70 years of age with severe sleep-disordered breathing, and suggests a specific link between this condition and death from coronary heart disease in men. Sleep-disordered breathing is characterized by a collapse of the upper airway during sleep, leading to numerous, brief interruptions of breathing known as sleep apnea, and it is experienced by one in four men and one in ten women.
A new method using nanomagnets which enables cells to be targeted to sites of injury in the body is published today by University College London researchers in The Journal of the American College of Cardiology: Cardiovascular Interventions. In response to the research part-funded by the charity, Professor Peter Weissberg, Medical Director at the British Heart Foundation, said: "This encouraging research shows that nanomagnets could be used to help therapeutic stem cells reach specific areas of the body, particularly inside blood vessels where the blood is flowing fast and at high pressure. "It is hoped that this strategy could be used to help these cells home-in to the sites of diseased tissue and improve the chances of repairing it.
Stop ten women on the street and ask them what their biggest health risk is, and, chances are, more than half of them would answer " breast cancer ." They would be wrong. Taking the life of one woman every minute, heart disease is the leading cause of death of women in America. Unfortunately, most women put their own needs behind the needs of their families, rarely considering the risks and dangers of this devastating disease. To address such widespread lack of awareness, The Main Line Health Heart Center announces the launch of its Women's Heart Initiative, a one-of-a-kind team of physicians and clinical staff in southeast Pennsylvania, designed specifically to empower women in taking charge of their cardiovascular health.
Angina puts men at greater risk of heart attack and death than women, says new research from the UK that suggests men with angina have twice the risk of having a heart attack and are three times more likely to die of heart disease or an illness linked to it than women with angina. The study was conducted by researchers in Scotland and Ireland led by Dr Brian Buckley of National University Ireland (NUI), Galway, and is published online on 6 August in BMJ. Angina is a common condition in the UK, affecting some 4.8 per cent of men and 3.4 per cent of women in England and 6.6 per cent of men and 5.6 per cent of women in Scotland. Angina is often the first sign of ischaemic heart disease.
A study in the Aug. 15 issue of the Journal of Clinical Sleep Medicine shows that adults with Down syndrome also frequently suffer from obstructive sleep apnea (OSA). However, complications of untreated OSA such as cardiovascular disease, daytime sleepiness and impaired cognitive functioning overlap with the manifestations of Down syndrome; therefore, OSA may not be detected. Results indicate that 94 percent of subjects with Down syndrome had OSA; 88 percent had at least moderate OSA with an apnea-hypopnea index (AHI) of more than 15 breathing pauses per hour of sleep; and 69 percent had severe OSA with an AHI of more than 30. Twelve of the 16 subjects with Down syndrome were obese, and there was a significant correlation between body mass index (BMI) and AHI.
A team of researchers from CIC bioGUNE from the Cellular Biology and Stem Cell Unit, alongside a team from Paris' Cardiovascular Research Centre (INSERM U970) have developed a new area of research which looks extremely promising as regards the development of new therapeutic responses to ischemic pathologies and cardiovascular diseases in general. The results of this research project, which was initiated in 2005 and is supported by Bizkaia:Xede and the Basque Government's Etortek programme, were published in the prestigious scientific journal Circulation. By activating a protein called HIF, the strategy is to stimulate revascularisation and the repair of the damaged organ following ischemia caused by the obstruction of a blood vessel preventing normal blood flow.
