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.

Latest Heart Disease News and Research

Two heart nerve cell types sustain cardiac stability in mice

Researchers identified two major intrinsic cardiac neuron populations in mice: Npy-positive neurons regulate parasympathetic heart rate control and support coronary perfusion, while Ddah1-positive neurons help maintain electrical stability during extreme stress. Removing Npy-positive neurons caused fatal cardiac failure, whereas loss of Ddah1-positive neurons increased susceptibility to malignant arrhythmias and sudden cardiac arrest under stress.

Endotrophin may reveal metabolic risks linked to changing body fat

Researchers have identified a biological marker that rises and falls as body fat changes, offering new insight into how weight gain and weight loss may influence metabolic health.

Study reveals how DNA misfolding causes congenital heart disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes for this disorder is having only one functional copy of the gene TBX5, instead of two healthy copies, inherited from parents.

Modifiable cardiovascular risk factors linked to unstable coronary artery plaques

Cardiovascular risk factors are linked to higher risk of heart disease, but it has been unknown how they are related to abrupt closure of the coronary arteries leading to heart attack and sudden cardiac death.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Multiple sclerosis mortality trends underscore need for comprehensive patient care

An analysis of more than 42,000 U.S. deaths linked to multiple sclerosis (MS) found that death rates varied by age, geography, and race and ethnicity, with Black patients dying younger than white patients and high blood pressure emerging as a growing contributor.

Urbanization reshapes gut microbiomes across diverse South Asian communities

Urbanization is one of the most consequential demographic shifts of the 21st century. As communities move from traditional or rural to urbanized ways of life, changes in diet, lifestyle, and environmental exposures can influence many aspects of human biology and health.

Red meat intake emerges as a potential pancreatic cancer risk factor

A systematic review and meta-analysis of 16 studies involving nearly 2 million participants found that higher red meat intake was associated with a modestly higher risk of pancreatic cancer. Processed meat intake showed no statistically significant association, although variation between studies means a small effect cannot be excluded.

Generic semaglutide could improve diabetes treatment affordability in Canada

In a novel analysis examining the economic implications of generic semaglutide entering the Canadian market, researchers predict that the anticipated price reductions of up to 70% will dramatically increase both the cost-effectiveness and health system affordability of therapy options for patients with type 2 diabetes and high cardiorenal risk.

ACC introduces cardiogenic shock designation to improve heart attack care

The American College of Cardiology (ACC) is introducing a new cardiogenic shock designation to improve outcomes for one of the most life-threatening complications of a heart attack.

Adverse pregnancy outcomes increase future peripheral artery disease risk

Women who experience pregnancy complications such as gestational diabetes, preeclampsia, or preterm delivery have a significantly increased long-term risk of developing peripheral artery disease (PAD) later in life, according to a new study published July 21st in the open access journal PLOS Medicine by Casey Crump of the University of Texas, US, and colleagues.

Moderate coffee intake may support heart health, AHA says

The American Heart Association finds that habitual coffee consumption is associated with lower risks of several cardiovascular outcomes, although most evidence comes from observational studies. Moderate intake is generally safe for most adults, while energy drinks and individual caffeine sensitivity may increase cardiovascular concerns.

Common heart risk calculators effectively predict certain types of cancer

Risk calculators that doctors use to estimate a person's risk of a heart attack or stroke work about as well for predicting certain cancers, according to a new study by UCL (University College London) researchers.

Experts urge focus on prevention to tackle global heart failure

Heart failure already affects more than 60 million people worldwide and is one of the leading causes of hospitalization among people over the age of 65.

Thymus hormone identified as key player in reversing age-related inflammation

Chronic, low-grade inflammation in the body-a phenomenon known as "inflammaging" because it increases with age-has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases.

Scientists link genetic spelling mistakes to sudden cardiac death

Scientists have found that the 'sudden' cardiac death condition related to high profile deaths or major medical episodes of sports stars including Fabrice Muamba, Christian Erikson and Mark-Vivian Foe has numerous linked gene variations, or "spelling mistakes", which highlights a potentially treatable vulnerability.

Study examines the link between blood type and cardiovascular risk in hemodialysis patients

Do you know your blood type? It is important information that is used for blood transfusions, but few realize blood types could also be linked to disease risks. In the general population, people with blood type O have been reported to have a lower risk of cardiovascular disease and cardiovascular mortality.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

Spring clock change increases retinal vascular disease risk, study finds

For the first time, Northwestern Medicine scientists have detailed how the semiannual clock changes impact a person's risk of developing retinal vascular disease, a group of disorders that affect blood vessels in the retina and can lead to vision loss.
