Serious cases of "long-haul COVID-19" are rare in patients who were not hospitalized after their infection, but these patients still report more doctor or health care visits after recovery,. Danish researchers report.
The new six-month study found that COVID patients who were not hospitalized had small increased risks of blood clots and breathing difficulties. They were also more likely t...
If you plan to resume running after an extended break due to the COVID-19 pandemic, you need to ease back in, one expert advises.
"There are a lot of good programs, including Couch to 5K or C25K, that focus on increasing running slowly up to about 3 miles or 30 minutes," said physical therapist Grace Neurohr, a running and bio-motion specialist for the Rubin Institute for Advanced Orthope...
The United States should resume administering the Johnson & Johnson COVID-19 vaccine, a key advisory panel for the Centers for Disease Control and Prevention voted on Friday.
The agency's Advisory Committee on Immunization Practices (ACIP) has determined that the benefits of the vaccine in preventing deaths and hospitalizations far outweigh the risks of rare blood clots, risks that are ma...
It may not be a good idea to take a daily low-dose aspirin if you're also taking a widely used class of blood thinners called direct oral anticoagulants (DOACs), researchers caution.
DOACs include drugs such as Eliquis (apixaban), Pradaxa (dabigatran), Lixiana (edoxaban) and Xarelto (rivaroxaban). They're used to help prevent strokes from atrial fibrillation or for the treatment of what's...

Among COVID-19 patients in intensive care units (ICUs), 2% suffer a stroke, a new study finds.
Of the two types of stroke, hemorrhagic stroke, which is caused by bleeding in the brain, was linked to a higher risk of death than ischemic stroke, which is caused by a blood clot in the brain. Data on just under 2,700 patients was used for the study.
The fate of Johnson & Johnson's coronavirus vaccine hung in the balance on Thursday after a government advisory committee said it needed more time and evidence to determine whether unusual, but severe, blood clots seen in a handful of people were caused by the vaccine.
So far, only six clotting cases have been officially reported out of more than 7 million shots given of the one-dose...

Extremely rare but life-threatening blood clots linked to the Johnson & Johnson COVID-19 vaccine appear similar to those caused by the AstraZeneca vaccine approved for use in Europe and Canada, U.S. health officials said Tuesday.
Federal officials called for a "pause" in use of the one-dose J&J vaccine while they review data linked to six women between 18 and 48 years of age who developed...
Doctors might have figured out why AstraZeneca's COVID-19 vaccine may cause life-threatening blood clots in very rare cases.
The discovery, made in a pair of reports published online Friday in theNew England Journal of Medicine, could be key to the global rollout of the AstraZeneca vaccine, helping develop effective treatments for the side effect and providing clue...
Time is never more precious than in the minutes after a stroke. Now, research is confirming that a "mobile stroke unit" can rush aid to patients quickly, potentially saving lives.
"Patients who are treated early benefit from a complete reversal of stroke symptoms and avoidance of disability," said lead study author Dr. James Grotta. He is director of stroke research at the Clinical Instit...
It's already being taken by millions to help ward off heart issues, and now preliminary research hints that daily low-dose aspirin might also cut your odds of contracting COVID-19.
As the Israeli research team noted, aspirin is an anti-inflammatory and previous studies have shown that it may help the immune system combat some viral infections. According to the researchers, aspirin was wid...

Giving blood thinners to COVID-19 patients soon after they're hospitalized could reduce their risk of dying.
That's the conclusion of a new study that analyzed data from the U.S. Department of Veterans Affairs on nearly 4,300 patients, average age 68, who were hospitalized with COVID between March 1 and July 31.
Of those, more than 84% received blood thinners within 24 hours of admi...
Full doses of blood thinners can benefit patients hospitalized with COVID-19, but the severity of their illness matters, researchers say.
The new global analysis found that hospitalized patients with moderate COVID-19 may benefit from the drugs' clot-preventing powers, but patients with illness so severe it requires admission to an intensive care unit may not.
Women who have COVID-19 during childbirth are more likely to face complications than moms-to-be without the coronavirus, researchers say.
Fortunately, the absolute risk for complications for any one woman is very low (less than 1%). But the relative risks for problems -- such as clotting and early labor -- are significant, the new study found.
Treating COVID-19 patients with high doses of blood thinners doesn't appear to help them and could be harmful, researchers report.
"COVID-19 patients appear to have an increased incidence of blood clots. Many hospitals and health care providers began to use high doses of blood thinners to prevent these clots or treat them preemptively," explained study co-author Dr. Juan Reyes, director o...
After administering clot-busting drugs to treat a stroke, using blood pressure cuffs to squeeze each arm might aid recovery, a new, small Chinese study suggests.
In the technique -- called remote ischemic post-conditioning -- the flow of oxygen-rich blood is repeatedly interrupted and restored using blood pressure cuffs on the arms. Earlier studies have found that the technique may p...
Hospitalized COVID-19 patients face an increased risk of developing dangerous blood clots, a new review indicates.
The odds of a clot are highest for the most critically ill patients. Analysis of 66 studies found that 23% of COVID-19 patients in an intensive care unit (ICU) developed a blood clot in the leg, known as a deep vein thrombosis (DVT).
Most strokes strike when an artery in the brain suddenly becomes blocked, but new research shows a rarer cause of strokes is becoming more common.
It's called cerebral venous thrombosis (CVT), and it happens when a vein in the brain is clogged. While CVT is estimated to cause less than 1% of all strokes, scientists discovered it is now more prevalent and affecting a different demo...
COVID-19 is linked to potentially fatal blood clots. Researchers now believe they've found out how they occur, which potentially could lead to better treatment.
"While many forms of illness can generate blood clots, the endothelial cells that line the inside of blood vessels play a surprisingly large role in COVID-19 clotting," said researcher Dr. Alfred Lee, an associate professor o...
In a small French study, three-quarters of all COVID-19 patients admitted to intensive care went on to experience a dangerous blood clot in the leg that can travel to the lungs and potentially cause death.
Known as a DVT, the condition first gained notoriety as so-called "economy class syndrome," when passengers on long-haul flights developed them after sitting still for too long. Bu...
New research reveals that COVID-19 attacks the lungs in a far different manner from the flu.
Unlike most respiratory diseases, significant impacts on blood vessels were seen in the lungs of seven COVID-19 patients. The lung tissue of those patients was compared to lung tissue from seven people who died of pneumonia caused by the flu.
A new study offers reassurance that many surgery patients can safely be freed from one discomfort of recovery -- wearing compression stockings to prevent blood clots.
The garments, which help keep blood from pooling in the lower legs, have long been used post-surgery. One reason has been to thwart blood clots, which can form in the leg veins when a patient is laid up in recovery.
The new coronavirus isn't just attacking the lungs: New research shows it's causing harm to the gastrointestinal tract, especially in more advanced cases of COVID-19.
A variety of imaging scans performed on hospitalized COVID-19 patients showed bowel abnormalities, according to a study published online May 11 in Radiology. Many of the effects were severe and linked with clots a...
As more evidence emerges that COVID-19 is tied to an increased risk of dangerous blood clots, new research suggests that giving patients blood thinners may improve their odds of survival.
"Using anticoagulants should be considered when patients get admitted to the ER and have tested positive for COVID-19, to possibly improve outcomes," study senior author Dr. Valentin Fuster, physicia...
Stress placed on the heart by COVID-19, a hesitancy by people to call 911, and even reluctance on the part of bystanders to perform CPR may be boosting rates of out-of-hospital cardiac arrest, a new report finds.
The data comes from four provinces in northern Italy, a region that was hit very hard and very early by the coronavirus pandemic.
As the toll of the COVID-19 pandemic grows, it is increasingly clear the infection is more than a lung disease. Many patients are developing heart complications, though the reasons are not fully understood.
People with heart disease or a history of stroke are at increased risk of the coronavirus infection, and of suffering more severe symptoms, according to the American Heart Associat...
People with a history of certain cancers have more than double the risk for the heart rhythm disorder atrial fibrillation, a new study says.
A-fib is a common disorder that can lead to palpitations, dizziness and fatigue. Untreated, it can cause blood clots, stroke and heart failure, and people with a-fib have five times the risk of stroke than other people.
Fewer U.S. veterans are having leg amputations or dying due to serious blockages in leg arteries, a new study finds.
These blockages are called critical limb ischemia (CLI). They can cause severe leg pain, wounds that don't heal and poor quality of life, according to the study published recently in the journal Circulation: Cardiovascular Interventions.
Ambulances outfitted as "mobile stroke treatment units" provide faster treatment and reduce patients' risk of severe disability and death, German researchers report.
The new study examined the use of three mobile stroke units in Berlin. Each unit is staffed with emergency medicine neurologists and has a CT scanner and lab on board that enables treatment at the scene.
