New guidelines for CT-guided biopsies of lung nodules significantly reduce radiation exposure, allowing individuals the benefit of the procedure, which may cut down on overall lung cancer deaths. This research was presented at the Society of Interventional Radiology's (SIR) 37th Annual Scientific Meeting in San Francisco.

Incidences of renal complications, specifically acute renal failure (ARF) and new hemodialysis (HD), continue to increase significantly among Medicare beneficiaries (MB) admitted for percutaneous coronary intervention (PCI). This was according to a study presented last week at the American College of Cardiology’s (ACC) 61st Annual Scientific Session.


A new comparative effectiveness study found older adults with stable coronary disease who underwent coronary artery bypass graft had better long-term survival than those who underwent percutaneous coronary intervention. However, the some experts disagree it was a fair appled-to-apples comparison.

April 3, 2012 – Abiomed Inc. today announced the successful first human use of the Impella cVAD device, a new, percutaneous Impella ventricular assist device (VAD) that provides peak flow of approximately 4 liters of blood per minute. The Impella cVAD is designed to provide temporary circulatory support and reduce the workload of the heart muscle via a minimally invasive, catheter-based pump that is inserted percutaneously in the cardiac catheterization lab, without the need for surgical intervention.


Stress tests are an important tool to help diagnose narrowed arteries in people who come to the emergency room (ER) with chest pain but are not confirmed as having a heart attack. Scheduling a follow-up exercise stress test before patients leave the ER more than doubles their likelihood of following through with the test, according to research presented at the American College of Cardiology’s 61st Annual Scientific Session in Chicago.

It seems a picture is worth more than a thousand words for people who see evidence of coronary artery disease, the most common type of heart disease in men and women. Simply seeing a build-up of calcium in the walls of arteries appears to prompt patients to better adhere to both statin therapy and recommendations for weight loss, according to research presented at the American College of Cardiology’s 61st Annual Scientific Session in Chicago.
