O filtro HEPA reduz as partículas respiratórias transportadas pelo ar geradas durante exercícios intensos

Aerossóis respiratórios são um componente comum da respiração e são uma forma comum de vírus respiratórios, como o COVID-19 , se espalharem para outras pessoas e superfícies. Os pesquisadores que realizam testes de esforço físico para pacientes cardíacos na Mayo Clinic descobriram que praticar exercícios em níveis crescentes de esforço aumentava a concentração de aerossol no ambiente ao redor. Eles também descobriram que um filtro de ar particulado de alta eficiência (HEPA) filtrou de forma eficaz os aerossóis e diminuiu o tempo necessário para limpar o ar entre os pacientes.

El filtro HEPA reduce las partículas respiratorias transmitidas por el aire que se generan durante el ejercicio intenso

Los aerosoles respiratorios son un componente común de la respiración y constituyen una vía común de propagación de virus respiratorios como la COVID-19 a personas y superficies. Los investigadores que realizan pruebas de esfuerzo físico en pacientes con problemas cardíacos en Mayo Clinic hallaron que el ejercicio a niveles mayores de esfuerzo aumentaba la concentración de aerosoles en el entorno circundante. Además, descubrieron que el filtro recogedor de partículas de alta eficiencia (HEPA, por sus siglas en inglés) descartaba de manera eficaz los aerosoles y disminuía el tiempo necesario para purificar el aire entre los pacientes.

Intensive Lifestyle Intervention Is Beneficial for Most People with Type 2 Diabetes, But Not All

For people who are overweight or obese and have type 2 diabetes, the first line of treatment is usually lifestyle intervention, including weight loss and increased physical activity. While this approach has cardiovascular benefit for many, it can be detrimental for people who have poor blood sugar control, according to a study conducted by researchers at Wake Forest School of Medicine.

Using Stimuli-Responsive Biomaterials to Understand Heart Development, Disease

The heart cannot regenerate new tissue, because cardiomyocytes, or heart muscle cells, do not divide after birth. However, researchers have now developed a shape memory polymer to grow cardiomyocytes. Raising the material’s temperature turned the polymer’s flat surface into nanowrinkles, which promoted cardiomyocyte alignment. The research is part of the growing field of mechanobiology, which investigates how physical forces between cells and changes in their mechanical properties contribute to development, cell differentiation, physiology, and disease.

Cardiac Calcium Scoring Saves One Man’s Life

The imaging procedure (called a CT Calcium Scoring scan) a CT or CAT scan, is a preventive cardiovascular screening test that is painless and noninvasive and takes only 10 minutes. Electron Beam Computed Tomography (EVCT) beam detects and measures the amount of calcium in the heart’s arteries. The more calcium that is present, the greater the likelihood of developing heart disease or having a heart attack or stroke. The test provides patients and their health care providers with the most accurate available “picture” of their current risk of developing heart disease or experiencing a heart attack.

COVID-19 Patient Outcomes Affected By Cardiovascular Risk

DALLAS – Nov. 17, 2020 – Research presented today by UT Southwestern cardiologists at the annual American Heart Association (AHA) Scientific Sessions 2020 showed that Black and Hispanic people were more likely to be hospitalized with COVID-19 than white patients, and that nonwhite men with cardiovascular disease or risk factors were more likely to die.

Young survivors of acute myeloid leukemia have long-term complications from treatment

Adolescent and young adult (AYA) patients treated for acute myeloid leukemia (AML) have a high risk of developing several long-term health complications after treatment, a study led by UC Davis Comprehensive Cancer Center researchers has found. The most common complications were cardiovascular, endocrine and respiratory diseases. The complications – known as late effects – were more present among non-white AYA patients and those living in more deprived neighborhoods.

Children with Kawasaki Disease at Higher Risk for Heart Problems More Than 10 Years After They Leave the Hospital

New research shows that children with Kawasaki Disease remain at an increased risk for cardiovascular events more than 10 years after hospitalization for their condition, highlighting the need for long-term heart disease surveillance and risk reduction strategies for these young patients. Details of the study was presented at ACR Convergence, the American College of Rheumatology’s annual meeting.

Cleveland Clinic Study Identifies Weight-Loss Threshold for Cardiovascular and Survival Benefits in Patients with Obesity and Diabetes

A Cleveland Clinic study shows that 5 to 10 percent of surgically induced weight loss is associated with improved life expectancy and cardiovascular health. In comparison, about 20 percent weight loss is necessary to observe similar benefits with a non-surgical treatment. The findings also show that metabolic surgery may contribute health benefits that are independent of weight loss. The study is published in the October issue of Annals of Surgery.

MedStar Washington Hospital Center Again Ranks Among Top U.S. Hospitals for Cardiovascular Care

MedStar Washington Hospital Center has again been recognized as one of the top 50 cardiovascular centers in the country. The Hospital Center’s Cardiology and Heart Surgery program moved up four spots from last year’s survey, to No. 37, in the 2020-21 U.S. News & World Report “Best Hospitals” rankings. It also received the highest rating possible in aortic valve surgery, congestive heart failure, heart bypass surgery, and transcatheter aortic valve replacement (TAVR).

Baylor Scott & White Health Again Recognized as Most Awarded Not-for-profit Health System in Texas by U.S. News & World Report

In the midst of the extraordinary health challenge presented by the COVID-19 pandemic, Baylor Scott & White Health remains committed to quality, safe care and helping Texas communities navigate the uncertainty of the SARS-CoV-2 virus. Today, this commitment to safety and quality is recognized as U.S. News & World Report releases its 2020-2021 Best Hospitals list.

New Research Supports Initial Conservative Management of Stable Coronary Artery Disease

New study results confirm that guideline-directed medical therapy is as effective as more invasive procedures at preventing death, stroke, and heart attack in patients with stable coronary artery disease (CAD).

The study results suggest that guideline-directed medical therapy should be the initial treatment strategy for patients with stable CAD.

The study results validate the evidence-based, guideline-directed, conservative treatment approach that the cardiovascular specialists at Nuvance Health have always used to treat CAD.

Study sheds light on differences in hospitalization-related care and outcomes for urgent cardiovascular conditions among homeless individuals

In a new retrospective study published today in JAMA Internal Medicine, a team of researchers led by Rishi Wadhera, MD, MPP, MPhil, an investigator in the Smith Center for Outcomes Research in Cardiology at Beth Israel Deaconess Medical Center (BIDMC), found that there are indeed striking disparities in in-hospital care and mortality between homeless and non-homeless adults.
