Some "Good" Cholesterol May Be Bad For Heart
It appears that in some cases, high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, does not protect against heart disease, and may even be harmful.

Predicting The Risk Of Sudden Cardiac Arrest Using Novel Imaging Could Better Identify Patients Who Would Benefit From ICDs
New research from the University at Buffalo suggests that cardiologists may have a new way to identify patients who are at the highest risk of sudden cardiac arrest, and the most likely to benefit from receiving an implantable cardiac defibrillator (ICD). ICDs are used to prevent sudden cardiac arrest in patients with advanced heart disease, but many patients' devices are never triggered...
