New device reduces hemostasis time following catheterization and improves efficiency

Early transradial compression band removal is safe and effective when used with hemostatic patch

2021-04-28

(Press-News.org) WASHINGTON, D.C, (April 28, 2021) - A new study reveals the use of a potassium ferrate hemostatic patch (PFHP) reduces the time to hemostasis for patients receiving cardiac catherization. The findings indicate a faster approach to removing the compression band used during the procedure, without compromising safety. Positive results of the STAT2 trial follow an initial pilot study and are being presented as late-breaking clinical science at the Society for Cardiovascular Angiography and Interventions (SCAI) 2021 Virtual Scientific Sessions.

Cardiac catherization is a procedure performed to evaluate the heart or arteries for patient diagnosis and interventions. This is increasingly performed using transradial approach, where a catheter is inserted through radial artery in the arm to the heart. A compression device called a TR band (TRB) is used to close the hole in the wrist made during the catherization process. Standard protocols require the band to be left on for at least two hours following the procedure.

The study evaluated the use of the StatSeal device patch compared to using a TRB alone in order to reduce time to hemostasis after transradial access. The study enrolled 443 patients across three centers, including 27.5% receiving percutaneous coronary intervention (PCI). Patients were randomized 1:1 to either the TRB alone or the TRB in addition to the potassium ferrate hemostatic patch. Both groups had complete TRB deflation attempted at 60 minutes post-procedure. Findings demonstrate the adjunctive use of the patch is safer and faster in deflating the TRB and reduced rebleeding. From a prior pilot study, discharge times were reduced with the use of the Statseal.

"By bringing observation times down from two hours to one, the use of the hemostatic patch has the potential to change practice because we can move toward same-day discharge protocols for cardiac catherization patients," said Arnold H. Seto, MD, MPA, FSCAI, Long Beach VA Health Care System. "We would be able to shift from long observation times and more frequently tell a patient, 'you are going home today.' This is really important for both the clinician and the patient."

Results showed the time to complete TRB deflation was shorter with the PFHP compared to for TRB alone (65.9 ± 14.1 min vs. 112.8 ± 56.3 min, P END

African Americans with coronary artery disease impacted by non-traditional risk factors

2021-04-28

WASHINGTON, D.C, (April 28, 2021) - A retrospective analysis of risk factors for coronary artery disease (CAD) in young African American patients is being presented today at the Society for Cardiovascular Angiography and Interventions (SCAI) 2021 Virtual Scientific Sessions. The findings reveal this specific patient segment, African-Americans under age 45, experiences greater CAD risk factors related to smoking, drug and alcohol abuse, HIV as well as mental health conditions including anxiety and depression. CAD is the most common type of heart disease, with high blood pressure, obstructive sleep apnea and diabetes among traditional risk factors. African Americans are disproportionally ...

Study: Significant decline in heart attack patients who sought care at peak of pandemic

2021-04-28

WASHINGTON, D.C., (April 28, 2021) - Results from a retrospective observational study, presented today at Society for Cardiovascular Angiography and Interventions (SCAI) 2021 Virtual Scientific Sessions, reveal a 70% decline in the number of patients presenting with acute myocardial infarction (AMI) during April 2020 compared to April 2019. While the number of patients with AMI seeking care at hospitals dropped during the pandemic, those that did receive care experienced more severe symptoms because of delays in patients seeking emergency services. AMI, commonly recognized as a heart attack, is responsible for more than one million deaths in the U.S. every year. For the best patient outcomes, seeking care within the ...

Causes of extreme weather and climate events in China during 2020/21

2021-04-28

During the summer of 2020, especially June and July, periods of extreme heavy rainfall occurred in China's Yangtze River Valley (YRV). These rain events caused the severest floods for the region since the summer of 1998. Despite this, the 2020 western North Pacific (WNP) typhoon season started slowly, but eventually produced 23 named tropical cyclones, still slightly below 27, the WNP seasonal average. As summer transitioned to winter, three severe cold surges swept most parts of China during late 2020 and early 2021, prompting the National Meteorological Center to issue its highest cold surge warning alert ...

Restricting internet searches causes stock market instability: study

2021-04-28

The research by RMIT University looked at the ramifications on the stock market following Google's withdrawal from mainland China in 2010. It found access to unbiased information about companies' performance - aided by unrestricted internet search results - led to investors making more informed decisions. On the flip side, search results manipulated to show overly positive information led to stocks for those companies being overvalued temporarily, increasing the stock market crash risk by 19%. The study has been published in the Journal of Financial Economics. Lead researcher Dr Gaoping Zheng, a lecturer in finance at RMIT, said the study showed search results influenced decisions, a challenge to previous thinking that they merely justified people's existing ideas. "Until ...

Early MR scans found more people with broken-heart syndrome

2021-04-28

In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging. Myocardial infarction is one of the most common diseases in the West, and is usually caused by a blood clot that blocks the coronary artery on the heart's surface. However, in up to ten per cent of all myocardial infarctions, no obvious cause ...

The state of China's climate in 2020: Warmer and wetter again

2021-04-28

The National Climate Center (NCC) of China has just completed a report that gives an authoritative assessment of China's climate in 2020. It provides a summary of China's climate as well as the major weather and climate events that took place throughout the year. This is the third consecutive year that the NCC has published an annual national climate statement in Atmospheric and Oceanic Science Letters (AOSL). "Against the background of global warming, extreme weather and climate events occur more frequently and have wide influence on society and economies. Last year, floods, droughts, typhoons, low-temperature freezing and snow disasters, and dust storms attacked ...

Cognitive neuroscience could pave the way for emotionally intelligent robots

2021-04-28

Ishikawa, Japan - Human beings have the ability to recognize emotions in others, but the same cannot be said for robots. Although perfectly capable of communicating with humans through speech, robots and virtual agents are only good at processing logical instructions, which greatly restricts human-robot interaction (HRI). Consequently, a great deal of research in HRI is about emotion recognition from speech. But first, how do we describe emotions? Categorical emotions such as happiness, sadness, and anger are well-understood by us but can be hard for robots to register. Researchers have focused on "dimensional emotions," which constitute a gradual emotional transition in natural speech. "Continuous dimensional ...

Study of marine noise highlights need to protect pristine Australian waters

2021-04-28

New Curtin research has found urgent action is needed to ensure man-made underwater noise in Australian waters does not escalate to levels which could be harmful to marine animals, such as whales, and negatively impact our pristine oceans. Lead author Professor Christine Erbe, Director of Curtin's Centre for Marine Science and Technology, said recent studies from the northern hemisphere showed man-made noise, in particular from ships, often dominates the underwater soundscape over large areas, such as entire seas, and could interfere with marine fauna that rely on sound for communication, navigation and foraging. "When ...

A simple exercise goal protects against unhealthy weight gain

2021-04-28

New research shows that physical activity equivalent to 100 PAI a week can counteract excessive weight gain. PAI stands for Personal Activity Intelligence and tracks how physically active you are throughout the week. You can measure PAI with just about any device that can measure heart rate. The activity metric has been developed by the Cardiac Exercise Research Group (CERG) at the Norwegian University of Science and Technology (NTNU) under the leadership of NTNU Professor Ulrik Wisløff. "Previously, we found that 100 PAI a week can give us a longer and healthier life without cardiovascular disease. Our new study shows that PAI can also help people maintain a healthy body weight," says researcher Javaid ...

More sleep or more exercise: the best time trade-offs for children's health

2021-04-28

More sleep could offset children's excess indulgence over the school holidays as new research from the University of South Australia shows that the same decline in body mass index may be achieved by either extra sleep or extra exercise. The striking new finding is part of a study that shows how children can achieve equivalent physical and mental health benefits by choosing different activity trade-offs across the 24-hour day. Conducted in partnership with the Murdoch Children's Research Institute, and supported by the National Heart Foundation of Australia, the team examined the optimal balance between children's physical activity, sleep, and sedentary time across the 24-hour day to better inform tailored ...
