Lower outdoor temperatures are associated with an increase in the risk of heart attacks, as per a newly released study by researchers at the London School of Hygiene and Tropical Medicine (LSHTM). For the study (reported in the British Medical Journal and released online today at bmj.com), the researcher, led by Krishnan Bhaskaran of LSHTM observed that each 1 degree C reduction in temperature on a single day is linked to around 200 extra heart attacks........ The occurence rate of acute myocardial infarction in Italy sharply increased, especially among young women, between the years 2001 and 2005, as per a comprehensive study funded by the Human Health Foundation (HHF), a nonprofit Italian charity for biomedical research and health education in Spoleto, Italy. The results were published in Aging Clinical Experimental Research....... For emergency department patients with shortness of breath and a risk of heart failure, physicians usually grab one thing first: a stethoscope. It allows them to hear the S3, an abnormal third sound in the heart's rhythm strongly associated with cardiac disease and heart failure. However, the low-frequency, low-pitch sound is notoriously very difficult to hear with a stethoscope alone........ These days people commonly don't die from a heart attack. But the damage to heart muscle is irreversible, and most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries. Stem cells now offer hope for achieving what the body can't do: mending broken hearts. Engineers and physicians at the University of Washington have built a scaffold that supports the growth and integration of stem cell-derived cardiac muscle cells. A description of the scaffold, which supports the growth of cardiac cells in the lab and encourages blood vessel growth in living animals, is published this week in the Proceedings of the National Academy of Sciences........ 
The prevalence of valvular heart disease, in particular stenotic aortic disease, increases with age and reaches 13% in individuals over the age of 75. Despite this the aetiology and molecular mechanisms remain unclear although several lines of evidence have suggested that its pathogenesis shares similarities to atherosclerotic disease, namely infiltration of inflammatory cells and [...]
Although diabetes mellitus is an established risk factor for coronary heart disease (CHD) and stroke, a number of questions remain. For example, to what extent is diabetes associated with fatal vs non-fatal myocardial infarction? How much of the effect of diabetes on vascular risk is due to the effect of diabetes on lipids [...]
