Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

How Traditional Chinese Medicine may reshape the gut microbiome to ease insulin resistance in PCOS

This review synthesizes evidence that gut microbiota dysbiosis contributes to insulin resistance and symptom severity in polycystic ovary syndrome through impaired barrier function, inflammation, and altered microbial metabolites. It evaluates how Traditional Chinese Medicine may modulate these pathways while highlighting major gaps in clinical validation, safety, and standardization.

Specific gut bacterium reduces weight gain and improves metabolic health

The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome-the bacteria and fungi in the gut-are associated with obesity and weight gain, raising the possibility that changing the microbiome could improve health.

Researchers identify partner protein that supports appetite regulating-protein

A protein essential to the human body for managing energy and regulating appetite relies on a partner protein, according to new research, and the findings could help researchers better understand genetic obesity.

AI enables rapid detection of coronary microvascular dysfunction from standard EKGs

Doctors may soon be able to diagnose an elusive form of heart disease within seconds by using an AI model developed at University of Michigan, according to a recent study.

Relationship quality impacts heart health, study shows

With heart disease as the leading cause of death worldwide, there is growing recognition that recovery is not only physical but also emotional and social. A new study shows that strong and supportive relationships can indeed improve heart health for individuals with cardiovascular disease.

First-of-its-kind mRNA system switches on therapeutic genes inside targeted cells

Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells-an advance demonstrated in studies in mice that could lay the groundwork for safer, more precise treatments for cancer and other diseases.

New data supports link between gum disease and heart disease

There is increasing evidence that gum disease is associated with increased risk of cardiovascular events, including heart attack, stroke, atrial fibrillation, heart failure and cardiometabolic health conditions. Effective prevention and treatment of gum disease, also called periodontal disease, could potentially decrease the burden of cardiovascular disease, according to a new scientific statement published today in the American Heart Association's flagship journal Circulation.

Mediterranean diet and healthy habits improve cancer survival rates

Being more physically active, following a balanced diet, not smoking, and keeping body weight and blood pressure under control: the same habits that protect the heart also prove decisive after a cancer diagnosis.

Smartwatch alerts help parents manage children's tantrums

Mayo Clinic researchers have developed a smartwatch-based alert system that signals parents at the earliest signs of a tantrum in children with emotional and behavioral disorders - prompting them to intervene before it intensifies.

Scientists create light-controlled versions of cholesterol

High levels of cholesterol are linked to heart disease, stroke, and many other health problems. However, this complex and vital fatty, water insoluble molecule-a lipid-is found in every cell of the body and is not all bad news. It also regulates crucial processes that science has yet to map.

Using sound waves to soften tumors and boost chemotherapy

Cancer is one of the leading causes of death in the U.S., second only to heart disease. But a new cancer treatment method from CU Boulder researchers uses sound waves to soften tumors and could be a potent tool against the disease.

Single-pill combination medications may simplify treatment for adults with high blood pressure

Taking one pill that combines two or more blood pressure medications may help adults with high blood pressure (also known as hypertension) lower their blood pressure level faster and more effectively than taking multiple medications separately, and it may also reduce the risk of heart attack and stroke, according to a new scientific statement published today in the American Heart Association's journal Hypertension.

E-cigarette use is linked to higher heart attack risk, especially in former smokers

This systematic review and meta-analysis examined whether electronic cigarette use is associated with myocardial infarction and stroke, synthesizing evidence from 12 observational studies. The analysis found higher odds of myocardial infarction among e-cigarette users, particularly former smokers, while no significant associations were observed among exclusive never-smokers.

Swapping high-carb snacks for tree nuts cuts food cravings in young adults at metabolic risk

Daily replacement of typical high-carbohydrate snacks with mixed tree nuts for 16 weeks reduced cravings for sweets and fast foods in young adults with early metabolic syndrome risk. This dietary swap improved overall diet quality, measured by the Healthy Eating Index, without increasing body weight or altering short-term glycaemic markers.

Indiana University physician joins FDA panel on male hormone therapy

Helen Bernie, DO, MPH, assistant professor of urology at Indiana University School of Medicine, will participate in an expert panel on testosterone replacement therapy and men's health to be held Wednesday, Dec. 10, by the U.S. Food and Drug Administration. Bernie's role on the panel is that of a clinical expert on men's reproductive health, which is the focus of both her practice and academic research.

Human heart organoids enable new therapies for atrial fibrillation

Though an estimated 60 million people around the world have atrial fibrillation, or A-fib, a type of irregular and often fast heartbeat, it's been at least 30 years since any new treatments have been developed.

Nighttime heart attacks cause less damage due to neutrophil circadian rhythms

Heart attacks that occur at night are less severe than those that strike during the day. A new study from the Centro Nacional de Investigaciones Cardiovasculares (CNIC) explains why. Published in the Journal of Experimental Medicine, the study led by Dr. Andrés Hidalgo's group at the CNIC shows that neutrophils-a type of white blood cell-have an internal clock that regulates their aggressiveness throughout the day and determines the extent of damage they cause to the heart after a heart attack.
