Patients with heart disease can lower cardiovascular risk factors with exercise, stress management

...s) with stable IHD and exercise-induced myocardial ischemia (decreased blood supply to the heart muscle). The trial was conducted from January 1999 to February 2003. Participants received either routine medical care (usual care); usual care plus supervised aerobic exercise training for 35 minutes 3 times per ...

Survival rates higher for children receiving living donor liver transplant

...not critically ill, who have shorter cold and warm ischemia times [the time the liver is not connected to a blood supply between procurement and transplantation], and who have fewer incidents of retransplantation with LDLT. Although LDLT poses risk to the donor, it is, as practiced, a valuable technique in pe...

Patients with metabolic syndrome, moderate coronary calcium have greater risk of blocked arteries

Where life's memories are stored

... neocortex. The damage was due to such problems as ischemia due to drug overdose, brain aneurysm, or encephalitis. They triggered patients' long-term memories by presenting them with "cue" words such as "river," "bottle," and "nail." The scientists asked the patients to recall events in their lives associated...

Study shows new imaging tracer clarifies cause of chest pain up to 30 hours after pain stops

...identified patients who had evidence of myocardial ischemia on a treadmill using a standard tracer called thalium to produce SPECT images. Later, SPECT images of the same patients were taken with the new tracer (Zemiva) injected at rest (without repeating the treadmill exercise), but no more that 30 hours aft...

Shortness of breath without chest pain can signify the presence of high risk heart disease

.... However, even after adjusting for the amount of ischemia statistically, shortness of breath remained predictive of an adverse outcome. The authors speculated that possibly inflammatory proteins that are associated with the development of coronary artery disease--proteins that have been associated with mala...

Jefferson researchers find drug may give some cardiac protection 24 hours after heart attack

.... Koch gave Darbepoietin to animals at the time of ischemia and heart attack, one to two hours after, and 24 hours later. In each case, the scientists saw that the drug offered significant protection to heart tissue, and even helped improve cardiac function. Dr. Koch believes the results "may be quickly tra...

Blocking the nerve receptor EP1 in mouse models reduces brain damage caused by stroke

Test to predict cardiovascular risk in heart attack patients not yet appropriately used

...th and/or electrocardiogram tests showing areas of ischemia in the heart. About 1.3 million Americans are hospitalized each year with NSTE ACS. During a 20-month period ending in 2004, 30,324 NSTE ACS patients were treated at 312 CRUSADE hospitals. A total of 19.4 percent of those patients had their BNP leve...

Fat cells around coronary arteries may play a role in heart disease

Understanding cell death may bring new life to kidney treatment

...ll regeneration that helps the kidney recover from ischemia is slower, he notes. The kidney normally has some capacity to regenerate, with surviving cells quickly stretching to cover holes left by dead cells and later dividing to form more cells for tissue repair. "Within a couple of hours, neighboring cells ...

Mayo Clinic Cancer Center on the forefront of the fight against multiple myeloma

...xamethasone included cerebral ischemia, myocardial ischemia and peripheral neuropathy. While overall survival rates are not significantly different between the two arms at this point, the follow-up is too short to observe disparities, and Dr. Rajkumar and his fellow researchers will continue to monitor the r...

Preventing spinal cord injury during aortic surgery

... severe deficits can be controlled through reduced ischemia time, the mere act of reintroducing blood and oxygen (reperfusion) also causes cellular damage. Ischemia-reperfusion injury exerts its effects on the spinal cord via release of reactive oxygen species, damage to cellular components such as mitochondr...

New cardiac MRI pinpoints closed arteries without surgery

...t timed intervals to see if there was heart muscle ischemia attributable to coronary artery blockage and if there was damage (either tissue death or scarring) that indicated a prior heart attack. In total, 46 patients with chest pain were enrolled in the study. All were scheduled to undergo coronary angiograp...

...ntinue to seek medications and therapies to reduce ischemia and angina over their lifetimes," said Bairey Merz, who holds the Women's Guild Chair in Women's Health at Cedars-Sinai. Compared with women who have blocked arteries, women with nonobstructive CAD are at lower risk for cardiovascular death, but the...
