Results from a new study suggest that exposure to high levels of traffic air pollution among people with heart or lung disease is associated with a risk factor for sudden cardiac death known as reduced heart rate variability (HRV).  Read More →

Exposure to high levels of traffic air pollution among people with heart or lung disease is associated with reduced heart rate variability (HRV), a risk factor for sudden cardiac death, finds a new study. The study included 30 Atlanta-area residents with lung disease (chronic obstructive pulmonary disease) or heart disease (previous heart attack).  Read More →

New studies on both frozen human heart tissue and mice have found evidence that a key enzyme involved in fetal heart development may contribute to the onset of the serious heart condition known as cardiac hypertrophy in adults.  Read More →

Only about one-third of cardiac patients were doing regular heart-healthy exercises a year after a heart attack, bypass surgery or angioplasty, researchers have found. The Case Western Reserve University research team followed 248 patients after they completed a 12-week cardio rehabilitation program to help train them to exercise. Exercise patterns in the longitudinal study were tracked through heart monitors worn by the patients. After one year,... 

Australian researchers have found that the dirtier the air, the more likely people are to suffer sudden cardiac arrest.  Read More →

From CBS News : How do you treat something that has no symptoms and goes undetected on standard screenings? DE-CMR (delayed enhancement cardio magnetic resonance) is a new cardiac imaging technique that can detect if you’ve suffered a silent heat attack, which an earlier EKG might have missed. Early Show medical correspondent Dr. Jennifer Ashton shared this new method of detection with Early Show co-anchor Julie Chen. According to Ashton,...
