Cardiovascular Research:Poor sleep associated with increased risk of heart attack, stroke ♦ Visualizing calcified coronary arteries ♦ Fructose powers a vicious circle

Visualizing calcified coronary arteries may be wake-up call to change lifestyle Looking at images of their own calcified coronary arteries may be a wake-up call for patients with newly diagnosed coronary artery disease to change their lifestyles.
Public divided on heart benefits from alcohol consumption In one of the first published studies using data from the Health eHeart Study, researchers have found that people are divided on the cardiovascular benefits of alcohol consumption. And, those who do perceive alcohol as 'heart healthy' drink substantially more than their counterparts.
Vinculin protein boosts function in the aging heart A team of researchers provide new insights on how hearts 'stay young' and keep functioning over a lifetime despite the fact that most organisms generate few new heart cells. Identifying key gene expression changes that promote heart function as organisms age could lead to new therapy targets that address age-related heart failure
Fructose powers a vicious circle Researchers have found a hitherto unknown molecular mechanism that is driven by fructose and can lead to cardiac enlargement and heart failure

Poor sleep associated with increased risk of heart attack, stroke Poor sleep is associated with increased risk of heart attack and stroke, according to results from a recent study. The study included a representative sample of 657 men aged 25 to 64 years with no history of heart attack, stroke or diabetes. In terms of sleep quality, very bad, bad or poor ratings were considered a sleeping disorder in the study. Cases of myocardial infarction and stroke were recorded over the next 14 years.
