MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.

Erectile dysfunction may be a sign that coronary artery disease is developing

"We think that erectile dysfunction represents the 'tip of the iceberg' of a systemic vascular disorder; thus potentially preceding severe cardiovascular events. Erectile dysfunction should be part of a cardiovascular risk assessment.

Bariatric surgery is a safe option for treating obese patients who have coronary artery disease

Large scale study to see if angioplasty can be safely performed in small hospitals

Cardiologists at Johns Hopkins have launched a nationwide study of more than 16,000 patients to see if a potentially life-saving procedure called angioplasty can be safely performed in smaller, community hospitals, easing access to the therapy for patients. Researchers expect to enroll the first study patients in early fall 2005.
