A recent study published in the New England Journal of Medicine found that abciximab, a blood-thinner, can help prevent heart attacks in patients with unstable angina who have high troponin T levels. The treatment reduced heart attack risk by 44% in these patients compared to those without elevated troponin T levels.
Researchers found that tumor oxygen levels and blood flow are not predictable, which could hinder radiation therapy and drug delivery. The study's findings challenge previous assumptions and highlight the importance of measuring tumor oxygenation and blood flow in human tumors.
Researchers at UB's Toshiba Stroke Research Center have developed a new dual contrast injection method, enabling neurosurgeons to characterize and treat arteriovenous malformations (AVMs) more effectively. The technique allows for precise measurement of blood flow rate, facilitating the accurate administration of a glue-like substance ...
A new study finds that Enhanced External Counterpulsation (EECP) is effective in reducing angina in individuals with coronary artery disease. EECP, a non-invasive therapy, has been proven to improve exercise tolerance and reduce angina attacks, offering relief for patients who suffer from this condition.
Researchers found that combining abciximab with two low-dose boluses of reteplase provided complete blood flow to up to 35% more patients than using abciximab alone or in combination with a single dose of reteplase. This new strategy may represent an exciting new step in treating most heart attacks.
Case Western Reserve University researchers are developing a new method to study blood flow through artificial heart components by mimicking the behavior of coal water slurries. This approach has revealed the importance of particle distribution and velocity in preventing blood clots, which can lead to stroke and death.
Researchers found that contrast echocardiography can detect blockage of small vessels leading to reduced tissue blood flow after a heart attack. The study validated the effectiveness of CE in measuring post-heart attack small vessel obstruction and compared it favorably to MRI.
Researchers use transcranial Doppler ultrasound to monitor brain activity as it happens, detecting increased blood flow during thinking and decreased flow when tasks are resolved. This technology has implications for treating mental illness, stroke recovery, and even lie detection.
A study by Johns Hopkins researchers reveals that long-term estrogen replacement therapy can increase blood flow to the heart and cause blood vessels to stay open wider and longer. This leads to a reduced risk of heart attack and improved coronary circulation.
Researchers develop a new family of drugs called neuroprotectants designed to minimize disabling damage to brain tissue after an ischemic stroke. A test of one such drug, lubeluzole, showed greater recovery in patients' ability to function and significantly less disability compared to those receiving a placebo.
A study in rats found that natural estrogen levels provide significant neuroprotection against stroke damage, sparing up to three times more brain tissue than male counterparts. Researchers are now investigating the optimal dose of estrogen for this effect and its potential as a brain-protective therapy.
Researchers found that people with only occasionally elevated blood pressure already had blood vessel abnormalities before the onset of sustained high blood pressure. The study suggests that vascular changes may lead to hypertension, rather than vice versa, in people.
