Ultrafiltration for heart failure

September 17, 2008

Lipids

We compared the use of early, minimally invasive ultrafiltration with usual care in patients with acute decompensated heart failure in a randomized controlled trial. Ultrafiltration therapy resulted in greater fluid removal than standard therapy and was shown to be a safe and effective alternative to loop diuretics for sodium and fluid homeostasis in patients with heart failure. More research is needed to identify those patients most likely to benefit from this approach.

High-resolution spiral computed tomography coronary angiography

September 17, 2008

Lipids

We evaluated the performance of the 64-slice spiral computed tomography coronary angiography scanner in 52 symptomatic patients with stable sinus rhythm and found that it was highly reliable in ruling out the presence of a significant coronary stenosis. This technique may be regarded as a suitable alternative to invasive coronary angiography.

Multislice CT angiography for the diagnosis of coronary artery disease: Are we there yet?

September 17, 2008

Lipids

Despite advances in cardiac testing, noninvasive methodologies remain limited in their accuracy to (1) determine the etiology of chest pain; (2) detect preclinical coronary artery disease; and (3) track the progression of atherosclerotic lesions in native and revascularized coronary vessels.

Preventing sudden cardiac death in young athletes: Are current preparticipation screening guidelines appropriate?

September 17, 2008

Lipids

Up to 100 sudden deaths occur among high school and college athletes each year in the United States, most commonly resulting from hypertrophic cardiomyopathy and other cardiac disorders. Studies have shown that preparticipation screening examinations that include a 12-lead electrocardiogram, which is not currently required in the United States, can identify asymptomatic athletes with hypertrophic cardiomyopathy. The current dilemma is how the United States, with its large population and emphasis on reducing health care costs, can realistically implement an effective prescreening process to identify these athletes.

A Closer Look- Athletic screening: A delicate balancing act

September 17, 2008

Lipids

When Hank Gathers collapsedon court during a college basketball game against Portland State on March 4, 1990, and later died, the event both jolted the national consciousness and set into motion changes in the athletic preparticipation screening process. Although another collapse had occurred just 4 months before, and an irregular heartbeat was detected at that time, Gathers was not compliant with the prescribed beta blocker and continued to play. An autopsy revealed that the 23-year-old Gathers suffered from cardiomyopathy.

Anomalous coronary circulation detected by coronary artery scanning

September 17, 2008

Lipids

An asymptomatic 66-year-old man with a history of nonobstructing carotid artery plaque and sleep apnea was referred for cardiac computed tomography (CT) scanning for risk stratification. He exercised on a regular basis with no symptoms and had normal results on at least 2 nuclear stress tests, the last test being performed only 12 months earlier.

Detection of anomalous origin of the coronary arteries-role of CT coronary angiography

September 17, 2008

Lipids

In this issue, Schubert and Helenowski present a very dramatic instance of an increasingly common application of computed tomography (CT) coronary angiography—detection of an anomalous origin of the coronaries (page 40).
