The Best Medicine Against Cholesterol And High Blood Pressure

Cholesterol is a waxy substance that comes from two sources: your body and food. Excess cholesterol can form plaque between layers of artery walls, making it harder for your heart to circulate blood.

Plaque can break open and cause blood clots. If a clot blocks an artery that feeds the brain, it causes a stroke. If it blocks an artery that feeds the heart, it causes a heart attack.

Heart disease, stroke and other cardiovascular diseases are among the leading cause of death and now kill more than 800,000 adults in the US each year. Two main reasons people have heart disease or stroke are high blood pressure and cholesterol.

Stroke Could be Better Predicted with Biomarker Discovery

Stroke is a leading cause of disability and death in the United States, affecting more than 795,000 Americans every year. But what if doctors were better able to predict who is likely to have a stroke, providing greater opportunity for prevention? Researchers have uncovered four biomarkers that could help do just that.

In a study published in the journal Neurology, researchers found that individuals who had higher levels of four inflammatory biomarkers in their blood were at greater risk for stroke than those with lower levels.

Study co-author Dr. Ashkan Shoamanesh, of McMaster University in Canada, and colleagues say that - while further research is needed to determine whether these biomarkers could be used in clinical practice - their findings could pave the way for better prevention and treatment of stroke.

Stroke occurs when the flow of oxygen-rich blood to the brain is reduced, causing brain cell death.

Blood Vessel-Forming Protein Could Offer Alternative to Heart Bypass Surgery

For patients with severe coronary artery disease, heart bypass surgery can reduce the risk of heart attack and improve overall quality of life. Now, researchers report the possibility of a new treatment that may be even more beneficial, without the surgery.

Coronary artery disease (CAD) is the most common form of heart disease in the United States, responsible for more than 370,000 deaths in the country every year.

The condition arises when plaque builds up in the coronary arteries, partially or fully blocking the flow of oxygen-rich blood to the heart muscle. This blockage can cause heart attack, angina - severe chest pain - and, over time, heart failure.

While lifestyle changes - such as adopting a healthy diet and regular physical activity - are considered key to improving CAD, some patients may require heart bypass surgery, which can help restore blood flow to the heart.

But, as with all surgery, it has its risks. These include chest wound infection, bleeding, stroke, heart attack, and kidney or lung failure.

Hypertension Prevalence Higher in Lower-Income Countries for the First Time

In an analysis of global health differences in hypertension occurrence, researchers find that high blood pressure is more common in low- and middle-income countries for the first time.

High blood pressure is the leading preventable risk factor responsible for disease burden worldwide. Raised blood pressure - which can result in cardiovascular disease,heart disease, stroke, and chronic kidney disease - was accountable for around 9-12 million deaths globally in 2013.

According to research published in the American Heart Association's journal Circulation, more than 30 percent of the adult population worldwide has high blood pressure, and 75 percent of those people live in low- to middle-income countries.

Previous reports have indicated that the prevalence of hypertension in low- and middle-income countries is on the rise, and is steady or decreasing in high-income countries. However, recent estimates of the differences between high blood pressure worldwide were unknown.

Could Magnesium Regulate Blood Pressure?

A round one third of adults in the United States have high blood pressure, only half of whom have their high blood pressure under control. New research, published in the American Heart Association's journal Hypertension, identifies magnesium as a potential remedy.

With high blood pressure affecting around 70 million people in the U.S. and increasing the risk of two of the leading causes of death for Americans - heart disease and stroke - preventing or controlling blood pressure is an essential healthcare objective.

Labeled the "silent killer," due to often having no warning signs or symptoms, high blood pressure is a common and often dangerous condition.

A meta-analysis, funded by the Indiana University School of Medicine Strategic Research Initiative, details positive results that show an association between a daily intake of magnesium and a reduction in blood pressure.

Magnesium is already recognized as essential for over 300 biochemical reactions in the body.

Inherited Cholesterol Disorder Significantly Boosts Heart Risks

People who inherit a genetic disorder that causes high levels of "bad" LDL cholesterol have an increased risk for heart disease and hardened arteries, a new study finds.

The condition is called heterozygous familial hypercholesterolemia. It's believed to affect about 1.5 million people in the United States, the researchers said.

The genes linked to this condition prevent the liver from removing LDL (low-density lipoprotein) cholesterol from the blood. This allows the bad cholesterol to build up. Doctors suspect this familial condition when LDL levels are above 190 milligrams per deciliter (mg/dL), the study authors explained.

How Much Salt is Too Much?

Salt intake has become a major health concern in the United States. An array of studies have claimed too much salt in the diet can increase the risk of serious illness, such as heart disease and stroke, prompting recommendations to lower salt intake. But how much is "too much" when it comes to salt consumption?

The Dietary Guidelines for Americans recommend that adults consume less than 2,300 milligrams of sodium each day - the equivalent to around 1 teaspoon of salt - as part of a healthy diet.

A report from the Centers for Disease Control and Prevention (CDC) released earlier this year, however, found that around 90 percent of adults and children in the U.S. consume more than the recommended sodium intake, with most adults consuming more than 3,400 milligrams daily.

Loneliness, Isolation Enhance CHD and Stroke Risk

YORK, UK — Although past research has shown a link between impaired social relationships and premature mortality, a new meta-analysis suggests there may also be a significant association with increased risk for coronary heart disease (CHD) and stroke.

The review of 23 papers and 181,006 total patients showed a 29% increased risk for incident CHD for those who had poor social connections, shown through loneliness and social isolation measurements, compared with those with better connections. The lonely and isolated patients also had a 32% increased risk for stroke.

The investigators, led by Dr Nicole K Valtorta (University of York, UK), note that loneliness often contributes to impaired coping methods, isolation affects self-efficacy, and both have been associated with decreased physical activity and increased smoking.

They add that future studies are needed to assess whether targeting these social characteristics "can help to prevent two of the leading causes of death and disability in high-income countries." But for now, "health practitioners have an important role to play in acknowledging the importance of social relations to their patients."

Immune cells self-healing brain after stroke

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

"This is in total contrast to our previous beliefs", says Professor Zaal Kokaia from Lund University in Sweden.

Zaal Kokaia, together with Professor of Neurology Olle Lindvall, runs a research group at the Lund Stem Cell Center that, in collaboration with colleagues at the Weizmann Institute in Israel, is responsible for these findings. Hopefully, these new data will lead to new ways of treating stroke in the future. The study was recently published in the Journal of Neuroscience.

When stroke occurs, the nerve cells in the damaged area of the brain die, causing an inflammation that attracts cells from the immune system. Among them you find monocytes—a type of white blood cells produced in the bone marrow.
