Though they remain a leading killer, heart attacks can be effectively treated provided they can be rapidly diagnosed following initial onset of symptoms. In a study appearing in this month's Molecular and Cellular Proteomics, researchers have identified cardiac myosin-binding protein C (cMyBP-C) as a potential new diagnostic biomarker for heart attacks, one that may be particularly valuable for mild attacks in which traditional diagnostic proteins may not be abundant enough. http://www.physorg.com/news179669113.html Medicine & Health Thu, 10 Dec 2009 12:06:44 EST news179669113 By measuring the total gene activity in organs relevant for coronary artery disease (CAD), scientists at the Swedish medical university Karolinska Institutet have identified a module of genes that is important for the recruitment of white blood cells into the atherosclerotic plaque. The findings, which are to be published in the open-access journal PLoS Genetics, suggest that targeting the migration of white blood cells in the development of atherosclerosis may help to reduce the risk for adverse clinical effects such as ischemia and myocardial infarction. http://www.physorg.com/news179147843.html Medicine & Health Fri, 04 Dec 2009 11:30:01 EST news179147843 Sulphonylureas, a type of drug widely used to treat type 2 diabetes, carries a greater risk of heart failure and death compared with metformin, another popular antidiabetes drug. http://www.physorg.com/news179134063.html Medicine & Health Fri, 04 Dec 2009 07:40:01 EST news179134063 A study based on a contemporary registry of patients with myocardial infarction (heart attack) indicates that even though hospitals that perform a higher number of angioplasties are more likely to follow evidence-based guidelines and have shorter times to the angioplasty procedure, there appears to be no significant difference in outcomes such as length of hospital stay or risk of death, according to a study in the November 25 issue of JAMA. http://www.physorg.com/news178308230.html Medicine & Health Tue, 24 Nov 2009 18:04:25 EST news178308230 Perceived poor managerial leadership increases not only the amount of sick leave taken at a workplace, but also the risk of sickness amongst employees later on in life. The longer a person has had a "poorer" manager, the higher his or her risk of for example suffering a heart attack within a ten-year period, according to a new thesis from the Swedish medical university Karolinska Institutet. http://www.physorg.com/news176397399.html Medicine & Health Mon, 02 Nov 2009 15:50:02 EST news176397399 In recent years, women, particularly younger women, experienced larger improvements in hospital mortality after myocardial infarction (MI) than men, according to a study published in the Oct. 26, 2009 issue of Archives of Internal Medicine. http://www.physorg.com/news175758379.html Medicine & Health Mon, 26 Oct 2009 07:00:01 EST news175758379 'No major role for fish' in the prevention of heart failure; only a possible beneficial effect in those with diabetes http://www.physorg.com/news173516458.html Medicine & Health Wed, 30 Sep 2009 08:01:19 EST news173516458 Heart problems may account for a huge share of deaths from influenza, according to a study published on Tuesday that recommends cardiac patients be vaccinated against flu. http://www.physorg.com/news172779555.html Medicine & Health Mon, 21 Sep 2009 19:30:01 EST news172779555 Levels of a biomarker used in the diagnosis of heart attacks are almost universally elevated in patients who have undergone coronary-artery bypass grafting (CABG) and, when markedly elevated, are powerfully prognostic, a team of researchers from the Massachusetts General Hospital (MGH) Heart Center has found. Their report implies that, while measurement of cardiac troponin T (cTnT) can help determine patient prognosis, current consensus recommendations regarding the use of cTNT to diagnosis post-CABG heart attack (myocardial infarction) probably should be reconsidered. The paper appears in the September 8 issue of Circulation and has been released online, http://www.physorg.com/news171296088.html Medicine & Health Fri, 04 Sep 2009 15:30:02 EST news171296088 Mortality rate following a heart attack has fallen by more than 50% in Europe over the past 25 years. However, because only minor advances in the medical treatment of AMI are expected over the next decade, it is through organisational changes in the pre-hospital phase that mortality rate will continue this decline to below 5%. http://www.physorg.com/news171006416.html Medicine & Health Tue, 01 Sep 2009 07:00:02 EST news171006416 Primary angioplasty (with stent implantation) is the most effective therapy for acute myocardial infarction (AMI), but it is not available to many patients, even though most European countries have sufficient resources (ie, catheterisation laboratories) for its wider use. The Stents 4 Life initiative was a study aiming to analyze the use of primary angioplasty in the treatment of AMI in 27 European countries. http://www.physorg.com/news171005461.html Medicine & Health Tue, 01 Sep 2009 06:50:02 EST news171005461 PCI is the preferred strategy in acute myocardial infarction when performed by an experienced team as soon as possible after first medical contact.Time is essential: for P-PCI there is an 8 percent excess annual mortality for every 30 min delay.A STREAM trial currently underway looks to ascertain whether the best strategy for patients who cannot receive P-PCI is early fibrinolysis together with mandated angiography. http://www.physorg.com/news170942920.html Medicine & Health Mon, 31 Aug 2009 15:10:01 EST news170942920 Several large observational data sets have convincingly shown that there is no overall safety issue with drug eluting stents (DES) vs. bare metal stents (BMS). In fact, most registry studies suggest a lower risk of death or myocardial infarction with drug eluting stents. However, late occurring stent thrombosis still remains higher and seems to be uniquely associated with these stents. Late stent thrombosis is a rare but very serious event and all possible efforts should be made to avoid the complication by improving patient selection, optimizing the implantation technique and enhancing anti thrombotic treatment. With highly effective anti thrombotic treatments and novel drug eluting stent designs without potentially toxic polymers a clear reduction of death and myocardial infarction rates is highly probable. http://www.physorg.com/news170942176.html Medicine & Health Mon, 31 Aug 2009 14:00:01 EST news170942176 A toxic cocktail of ultrafine particles is lurking inside road tunnels in concentration levels so high they have the potential to harm drivers and passengers, a new study has found. http://www.physorg.com/news170585437.html Space & Earth Thu, 27 Aug 2009 09:57:14 EST news170585437 A new study from NYU School of Medicine found that women may have a slightly higher risk of death than men in the thirty days following an acute coronary syndrome (ACS), but that these differences appear to be attributable to factors such as severity and type of ACS. The study, published in the August 26, 2009 issue of the Journal of the American Medical Association (JAMA), found however that overall there was no significant difference in mortality observed between the sexes after a heart attack. The large observational study pooled 136,247 ACS patients from 11 independent, international randomized clinical trials between 1993 and 2006. http://www.physorg.com/news170437772.html Medicine & Health Tue, 25 Aug 2009 17:00:02 EST news170437772 (PhysOrg.com) -- People with kidney disease undergo balloon dilation treatment after myocardial infarction less frequently, and therefore have a poorer prognosis.

The study also compared the rates of myocardial infarction (MI) and target vessel revascularization (TVR). http://www.physorg.com/news164376550.html Medicine & Health Tue, 16 Jun 2009 13:09:37 EST news164376550 Half of all patients who undergo myocardial infarction are experiencing onerous fatigue four months after the infarction. The patients who are most fatigued are those who perceive the infarction as a sign of chronic illness, those who experience the illness as difficult to control, and those who believe that the illness has a large impact on their life. These are the conclusions of a thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden. http://www.physorg.com/news163397555.html Medicine & Health Fri, 05 Jun 2009 05:13:02 EST news163397555 NewYork-Presbyterian Hospital and Columbia University Medical Center, together with the Cardiovascular Research Foundation (CRF), announced that its landmark study comparing the safety and efficacy of drug-eluting stents and bare-metal stents was published in the May 7 New England Journal of Medicine. The study, HORIZONS-AMI (Harmonizing Outcomes with RevascularIZatiON and Stents in Acute Myocardial Infarction), showed that in heart attack patients undergoing angioplasty, the use of paclitaxel-eluting stents reduces rates of target lesion revascularization (TLR) and binary angiographic restenosis when compared to the use of bare-metal stents after one year. http://www.physorg.com/news162566273.html Medicine & Health Tue, 26 May 2009 14:21:14 EST news162566273 The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years.
