Cardiovascular Research: PTSD increase risk of cardiovascular disease? ♦ Air pollution from wildfires may ignite heart hazards ♦ Body temperature may trigger cardiac death

New guidelines for statin eligibility improve prediction of cardiovascular risk The new guidelines for determining whether patients should begin taking statins to prevent cardiovascular disease issued in 2013 by the American College of Cardiology and the American Heart Association are more accurate and more efficient than an earlier set of guidelines in assigning treatment to adults at increased risk for cardiovascular events and identifying those whose low risk rules out the need to take statins.
Why does PTSD increase the risk of cardiovascular disease?  Post-traumatic stress disorder (PTSD) leads to overactive nerve activity, dysfunctional immune response and activation of the hormone system that controls blood pressure. These changes can ultimately increase risk of cardiovascular disease.
Body temperature may trigger sudden cardiac death When studying the proteins that underlie electrical signaling in the heart, and subjecting those proteins to conditions that are similar to the stress of exercise, researchers have found that in some cases, temperature can cause changes that trigger arrhythmia
Air pollution from wildfires may ignite heart hazards Air pollution from wildfires may increase risk of cardiac arrests, and other sudden acute heart problems, researchers have found. Researchers noted that while breathing wildfire smoke was linked to respiratory problems such as asthma -- evidence of an association between wildfire smoke exposure and heart problems has been inconsistent.
Personalized care for aortic aneurysms, based on gene testing, has arrived Researchers have tested the genomes of more than 100 patients with thoracic aortic aneurysms, a potentially lethal condition, and provided genetically personalized care. Their work will also lead to the development of a 'dictionary' of genes specific to the disease.
