APS is an autoimmune disease in which bacteria and virus-fighting immune system cells attack healthy body tissues and organs, according to the National Institutes of Health (NIH). As a result, abnormal blood clotting occurs.

For this study, the investigators examined the actions of APS antibodies on cultured endothelial cells, which line the inside of blood vessels. The scientists found that blood clot-inducing antibodies recognize a protein called Beta2-Glycoprotein I on the surface of endothelial cells. This surface then interacts with apolipoprotein E receptor (apoER2), a second protein, which inactivates the production of antithrombotic molecule nitric oxide. In turn, the decrease in nitric oxide initiates thrombosis.

By using mice models, the researchers also found that mice who are genetically predisposed to lack apoER2 can be protected from suffering blood clots when given APS antibodies.

Chieko Mineo, Ph.D., co-author of the study, said that in addition to these findings, the mechanisms that have been identified which promote thrombosis also occur "in APS during pregnancy to adversely affect the health of both the mother and the fetus."

The scientists said they are hopeful that this discovery will lead to new therapies to help prevent blood clotting, as well as pregnancy complications among APS patients.

A study published in the New England Journal of Medicine described the case of a particular 16-year-old with sickle cell anemia, which is an inherited condition in which the red blood cells are rigid and sickle-shaped.

Researchers reported that the patient received frequent blood transfusions due to abnormal blood flow in a particular artery in his brain. The transfusions were intended to prevent stroke but entailed a negative side-effect – the risk of iron overload.

The study's authors said that a number of blood disorders can result in iron overload from excess transfusions. These include thalassemia, sickle cell disease, myelodysplastic syndrome and aplastic anemia.

Since the body has no natural method for excreting excess iron, repeated transfusions can load the blood with high levels of the mineral, resulting in liver and endocrine problems. Chronic iron overload often results in serious and even fatal heart deterioration, the team added.

They found that by applying chelation therapy, the patient's health outcome improved. Chelation involves the application of chemicals that bind to heavy metals in the blood, allowing the kidneys to then filter them away.

Researchers concluded that iron-chelation may be an effective prophylactic treatment for individuals who receive repeated transfusions for blood disorders.

An estimated 4.5 million Americans require blood transfusions every year, according to the American Blood Centers.

Previous reports have found that an estimated 80 percent of all deaths among people with diabetes are caused by heart disease. Among the different types of these illnesses, cardiomyopathy—which leads to heart muscle damage—is the leading heart-related cause of deaths among diabetics.

During the recent trial, groups of rats with diabetes were either given a diet that contained garlic or corn oil. The researchers then observed the two animal groups to see which oil led to better prevention of cardiomyopathy.

The team of investigators discovered that because garlic oil contained a high amount of antioxidants, it reduced the risk of cardiovascular complications in the rats that consumed it as opposed to the animals that were fed corn oil.

The authors of the report concluded that "garlic oil possesses significant potential for protecting hearts from diabetes-induced cardiomyopathy."

Individuals who wish to find other natural alternatives to treating diabetes and protecting themselves against heart disease can benefit from eating grapes, according to a study conducted at the University of Michigan Health System. 

Surgeries, obesity and even prolonged air travel can increase the risk of DVTs, a condition that has a 3 percent mortality rate when untreated. So, if aspirin does not significantly affect DVTs, what does?

One possible solution is nattokinase. An extract obtained from a popular Japanese food, nattokinase may treat DVT and even cardiovascular disease, according to an article in the Journal of the American Academy of Physicians Assistants (JAAPA).

Nattokinase is an enzyme created by fermenting soybeans using a bacteria called Bacillus natto. Research has shown that it can have anticoagulant properties when taken in moderate doses.

A recent study found that airline passengers given three daily doses of nattokinase were less likely to develop a DVT during a flight.

While currently it is rarely used clinically, the article in the JAAPA suggests that further clinical trials of nattokinase may cement its potential health benefits.

According to research in the Circulation: Journal of the American Heart Association, extra pounds could result in blood clots. However, the locations are different depending on the gender.

It was found that men have a higher risk of blood clots when they have more weight around their waist, while women have a higher risk if they have extra pounds on their hips.

Originally, it was believed that women should be encouraged to have larger hips, as they may work as a protective shield against blood clots. This new research is running counter to that theory.

The researchers feel it’s because previous studies only measured body mass index (BMI) when studying blood clots, and didn’t pinpoint where the extra fat was located.

"The BMI is a marker of excess weight and correlates well with body fat content in adults; however, it fails to consider the distribution of body fat," explained study leader Dr. Marianne Tang Severinsen.

Nutritional supplements such as coumarins, which are found in various herbs, work as a blood thinner, and may be a good idea to take if you feel you’re at risk.

Over the course of four weeks, a total of 45 healthy people who were considered overweight ate foods enriched with anti-inflammatory nutrients, such as antioxidants, fiber and omega 3 fatty acids. Researchers designed the dietary regimen to prevent low-grade inflammation, which causes cardiovascular disease, diabetes and obesity.

The results showed that a person's bad cholesterol intake was reduced by 33 percent as well as the development of blood clots by 26 percent, blood lipids by 14 percent and high blood pressure by 8 percent. Furthermore, preventing inflammation slowed the brain's aging process, which protected against memory loss and cognitive degeneration.

"Drug or specific products with health claims affect only one or maybe a couple of risk factors," said Inger Björck, lead author of the research. She added that "by a combination of food you can in a simple and striking way affect many risk parameters simultaneously."

In the U.S., heart disease is the leading cause of death, followed by 6th-ranking Alzheimer's disease and diabetes as the 7th cause, according to the Centers for Disease Control and Prevention. 

Over the course of five and a half years, a team of researchers observed the mental and physical health of approximately 6,000 people.

During the study, an estimated 15 percent of the individuals were diagnosed with depression, and of this group, 20 percent had developed a form of heart disease. Furthermore, approximately 14 percent of the participants had cardiovascular problems.

At the end of the trial, a total of 170 people had passed away with 63 percent of the group dying from coronary heart disease. Also, suffering from a heart attack or stroke was the cause of death in 47 people.

The researchers discovered that individuals who had been diagnosed with depression and poor cardiovascular health were five times more likely to die compared to participants who were free of both health problems.

While other studies have suggested that depression can cause inflammation and the forming of blood clots, the team concluded that further studies will be needed to determine the biological causes of this mental disorder on heart health.

In 2006, an estimated 81.1 million Americans were diagnosed with at least one type of cardiovascular disease, including approximately 6.4 million suffering from strokes, the American Heart Association reports. 

A team of researchers at the University of California Irvine, led by cardiologists Subramaniam Krishnan and Miguel Salazar found the pouch-like form during an autopsy procedure. Following the discovery, the physicians collected data on ultrasound and computed tomography (CT) scans, and found that out of more than 700,000 cases of stroke, 30 percent to 35 percent of the victims have this deformity.

With nearly one-third of blood clot origins unknown in those who have suffered strokes, the team hopes that this discovery may help neurologists prevent future strokes in patients. More studies in the future will be needed in order to determine how much this structure may affect patients who have survived strokes.

"It was thought that the body of the left atrium was largely smooth and unlikely to be a source of blood clots, but we have found that not to be true for roughly one in three people," said Krishnan.

According to the American Heart Association, the rate of stroke-related deaths declined by nearly 34 percent from 1995 to 2005.

This is because researchers have discovered that blood clots that have formed abnormally may speed up the degeneration of cognitive function. In particular, studies have found cerebral amyloid angiopathy (CAA)—a peptide in blood vessel walls located in the brain that causes unusual development of blood clots—may increase a patient’s chance of Alzheimer’s.

Investigators are making efforts to combat this health complication, and developing treatments that could slow down the development of the memory disorder.

Using mice that had been genetically altered to display signs of Alzheimer’s disease, the team tried to lower fibrinogen levels, a protein that greatly contributes to blood clot development. By lowering the amount of fibrinogen in the blood, the animals had less CAA in their blood vessels, allowing the mice to have better performance in memory tests.

These results may lead to more advancements in medication developments that could protect against both Alzheimer’s disease and blood clots. For instance, researchers at the University of Maryland Medical Center recently discovered a compound that is a source of antioxidants, which help protect cognitive function and blood clots and could be used in prescriptions.

Researchers enrolled patients aged 40 years and older who suffered minimal mobility three days prior to the study and would be on bed rest at least three days after the trial began. Participants were given blood thinners for six to 14 days, followed by 28 days of continuing the medication or taking a placebo.

Patients were then examined right after the study ended, and then again six months later for blood clots and deep vein thrombosis, which is the forming of blood clots in leg veins.

The researchers discovered that only 2.5 percent of individuals who had taken the medication during the trial period had developed blood clots, while 4 percent of the placebo patients were diagnosed with clotting complications.

Roger D. Yusen, associate professor of medicine at Washington University, stated that "we currently treat acutely ill medical patients with a week or two of blood thinners to prevent clots." He added that "these results suggest that, depending on the patient, physicians may want to consider extending that treatment for an additional month."

In addition to extending the use of blood thinners, researchers at the Christiana Care Health System in Delaware found that administering a clot-dissolving drug followed by a clot-removing procedure can also prevent deep vein thrombosis.
