Using adrenaline in cardiac arrests results in less than one percent more people leaving hospital alive

Fri, 07/20/2018 - 15:49
A clinical trial of the use of adrenaline in cardiac arrests has found that its use results in less than 1 percent more people leaving hospital alive -- but almost doubles the risk of severe brain damage for survivors of cardiac arrest. The research raises important questions about the future use of adrenaline in such cases and will necessitate debate amongst healthcare professionals, patients and the public.

Diabetes during pregnancy may increase baby's heart disease risk

Thu, 07/19/2018 - 16:47
Gestational diabetes may increase the risk of blood vessel dysfunction and heart disease in offspring by altering a smooth muscle protein responsible for blood vessel network formation. Understanding of the protein's function in fetal cells may improve early detection of disease in children.

'Good cholesterol' may not always be good

Thu, 07/19/2018 - 08:54
Postmenopausal factors may have an impact on the heart-protective qualities of high-density lipoproteins (HDL) -- also known as 'good cholesterol.' The findings bring into question the current use of total HDL cholesterol to predict heart disease risk.

Switching to certain antidiabetic drugs linked to increased risk of major complications

Wed, 07/18/2018 - 18:36
For people with type 2 diabetes, switching to sulfonylurea drugs to control blood sugar levels is associated with an increased risk of complications compared with staying on the drug metformin, a new study finds.

Artery hardening and thickness not affected by stopping hormone therapy

Wed, 07/18/2018 - 12:48
Heart disease is still the number one killer of US women, and hormone therapy remains a top treatment for menopause symptoms. A new study connects these two facts to demonstrate little effect of hormone therapy on artery thickness as a precursor to heart disease.

HIV infection doubles risk of heart disease

Wed, 07/18/2018 - 10:47
People infected with HIV are twice as likely to suffer from heart disease, research has found. Analysis of global figures reveals that HIV-associated cardiovascular disease has more than tripled in the past 20 years as more people are living longer with the virus. The greatest impact is in sub-Saharan Africa and Asia Pacific regions, with Swaziland, Botswana and Lesotho particularly affected.

Omega 3 supplements have little or no heart or vascular health benefit

Tue, 07/17/2018 - 19:45
Omega 3 supplements have little or no effect on the risk of heart disease, stroke or death -- according to new research. Increased consumption of omega 3 fats is widely promoted globally because of a common belief that that it will protect against heart disease. But a new Cochrane review finds that omega 3 supplements offer little, if any, benefit.

High vinculin levels help keep aging fruit fly hearts young

Tue, 07/17/2018 - 11:25
A new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers have discovered that maintaining high levels of the protein vinculin confers health benefits to fruit flies. Their work shows that fruit flies bred to produce 50 percent more vinculin enjoyed better cardiovascular health and lived a third of their average life span longer.

While men lose more weight on low-carb diets, women show improved artery flexibility

Tue, 07/17/2018 - 11:24
According to the Centers for Disease Control and Prevention, an estimated 1 out of 3 American adults live with higher than normal blood sugar levels known as prediabetes. Researchers recently found that while men may lose more weight on low-carb diets, women actually see better improvements in artery flexibility. It's a finding that may help pre-diabetic women reduce their risk for heart disease through a low-carb diet.

Researchers trace Parkinson's damage in the heart

Fri, 07/13/2018 - 09:35
A new way to examine stress and inflammation in the heart will help Parkinson's researchers test new therapies and explore an unappreciated way the disease puts people at risk of falls and hospitalization.

Genetic risk of heart failure

Thu, 07/12/2018 - 10:04
Heart failure is known to be more common in certain families but whether this familial transition is caused by genetic or lifestyle factors. By studying adoptees in relation to both their biological parents and adoptive parents, a new population study in Sweden has found that genetic heritage is the dominant factor when it comes to heart failure in these families.

World Trade Center response crews may face higher heart attack, stroke risk

Tue, 07/10/2018 - 07:19
Post-traumatic stress disorder (PTSD) may increase the risk for stroke and heart attack in both male and female city workers and volunteers who cleaned debris in the aftermath of the World Trade Center plane attack on Sept. 11, 2001. The study sheds light on long-term consequences of PTSD 11-15 years after the event occurred in a general population.
