The ACS Presidential Sessions emphasize communicating science to the public, with speakers including Roger Tsien, Laura Kiessling, Samuel Stupp, J. Craig Venter, Carolyn Bertozzi, and Paul Raeburn. The sessions also explore innovative chemistry applications, such as producing fuels directly from sunlight.
A new study by Brigham and Women's Hospital found that cardiovascular disease and heart attack complications from PCI tend to occur within the first 30 days after treatment. The study analyzed patients who received anti-blood clotting drugs, with prasugrel showing a significant benefit in reducing these complications.
The FOCUS trial found that patients with chronic ischemic heart disease who received stem cell therapy had a significant increase in left ventricular ejection fraction, with improvements correlated to the number of progenitor cells in their bone marrow. This study provides valuable insights for future therapies and trials.
The International multicenter ADVANCE study found significant improvement in valve function and low mortality rates at 30 days after TAVI. The study analyzed data from 1,015 high-risk patients with severe aortic stenosis.
Researchers found that among patients given an appointment for a follow-up exercise stress test, 70 percent actually underwent the test compared to 31 percent without pre-scheduled appointments. Patients with pre-scheduled appointments also waited significantly less time for the test.
A sharp rise in blood pressure in midlife can increase a person's risk of heart disease later in life. Early detection and treatment of rapidly rising blood pressure may be required to prevent long-term damage to the heart.
A study led by Mayo Clinic researchers found that bone marrow-derived stem cells improved ejection fraction, a measure of the left ventricle's pumping ability, by 2.7% in patients with chronic heart failure. The most significant improvements were seen in younger patients and those with enriched CD34+ and CD133+ type of stem cells.
A study published in JAMA found that using bone marrow cells to treat chronic ischemic heart failure did not show significant improvements in most measures of heart function. However, exploratory analysis revealed a significant effect on left ventricular ejection fraction (LVEF) among patients under 62 years old.
A new class of platelet blockers has been shown to reduce the risk of recurrent cardiovascular events in patients with known atherosclerosis. Adding vorapaxar, an investigational platelet blocker, to standard antiplatelet therapy cuts the likelihood of another cardiac event by 13% compared to placebo.
A new, one-page checklist for heart failure patients significantly reduced hospital readmissions from 20% to 2%, with improved medication adherence and quality of care. The study suggests the checklist could save billions by improving patient outcomes and reducing healthcare costs.
Internet-based telemedicine systems lead to more timely treatment decisions and medication adjustments for patients with high blood pressure. Patients who reported frequent blood pressure readings via a web-based portal received more appropriate pharmacotherapy and an overall reduction in cardiovascular risk.
A new study found that using a patient's own bone marrow cells can help repair damaged areas of the heart caused by heart failure. The treatment increased left ventricular ejection fraction by a small but significant amount, and improved perfusion defects in patients with chronic ischemic heart disease.
A Canadian study reveals that non-cardiac co-morbidities such as COPD and chronic kidney disease are the main predictors of late mortality after TAVI, emphasizing the importance of closer patient evaluation and follow-up. The study also shows that valve performance is maintained throughout the follow-up period.
A team of researchers has developed a new tool to identify conserved motifs in the genomes of trypanosomatids, a group of parasites that include the causing agents of leishmaniasis and Chagas disease. The tool, named LeischCICS, uses bioinformatics tools to pinpoint potentially functional and regulatory sequences.
A study found that patients who viewed images of their coronary artery calcium scores were more likely to take statins as directed and lose weight, with compliance increasing as disease severity increased. This suggests that visualizing the extent of cardiovascular disease can motivate patients to adhere to recommended therapies.
A study found that dissections occur most frequently in the right coronary artery and bending areas, causing serious complications. Stenting was successful in treating the dissection in 75% of patients, but major in-hospital adverse events occurred in 54%.
