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

Researchers use multiview deep learning to enhance echocardiogram analysis

Heart disease is the leading cause of adult death worldwide, making cardiovascular disease diagnosis and management a global health priority. An echocardiogram, or cardiac ultrasound, is one of the most commonly used imaging tools employed by physicians to diagnose a variety of heart diseases and conditions.

Activating hypoxia signaling improves metabolism and bone health

Obesity is widely known for increasing the risk of diabetes and cardiovascular disease, but its damaging effects on the skeleton are often overlooked. Excess body fat can disrupt bone metabolism, weaken bone quality, and impair fracture repair.

Blood pressure readings may help identify future dementia risk

Measures of blood vessel health derived from routine blood pressure readings may help identify adults at increased risk for dementia, according to research being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Ultra-processed food consumption associated with increased risk for heart disease

People who consumed over nine servings of ultra-processed foods per day on average were 67% more likely to suffer a major cardiac event than people consuming about one serving of such foods per day, in a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Shingles vaccine linked to lower risk of serious cardiac events

People with heart disease who received a shingles vaccine had nearly half the rate of serious cardiac events a year later compared with those who did not get the vaccine, according to a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Brain breathing mechanism linked to persistent high blood pressure

A brain mechanism may explain why approximately 40% of people with hypertension continue to have high blood pressure despite taking medication. The discovery reveals potential targets for new treatments.

Global indicators identified to monitor health before pregnancy worldwide

The key health and social indicators needed for a new global system to monitor people's health before pregnancy have been identified for the first time by researchers at University College London and the University of Southampton.

New polygenic risk scores improve prediction of metabolic disease outcomes

Type 2 diabetes (T2D) and obesity are metabolic conditions with many causes, including overlapping and distinct genetic features.

Extended monitoring identifies many more severe pregnancy complication cases

Extending the monitoring period for severe pregnancy complications showed more than 40% of cases were missed using traditional delivery-focused monitoring, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251425 that extended monitoring from conception to 6 weeks postpartum.

Clinicians show modest response to elevated lipoprotein levels in low-risk patients

Elevated Lipoprotein(a) [Lp(a)] is an independent, genetically determined risk factor for atherosclerotic cardiovascular disease (ASCVD), with levels >50 mg/dL affecting 20–30% of the global population.

Skipping breakfast may raise metabolic syndrome risk

The link between skipping breakfast and metabolic syndrome highlights the need for dietary strategies to improve cardiometabolic health in at-risk populations.

U.S. cigarette smoking falls below 10% for the first time but millions still use tobacco

Analysis of the 2023–2024 National Health Interview Survey shows that 18.8% of U.S. adults use tobacco, while cigarette smoking has fallen to 9.9%, the first time it has dropped below 10% nationally. Despite this milestone, millions of Americans still use cigars, e-cigarettes, or smokeless tobacco, with notable disparities across age, income, occupation, and geography.

Updated guideline emphasizes earlier treatment for high cholesterol

The American College of Cardiology (ACC), the American Heart Association and nine other leading medical associations, today issued an updated guideline for the management of dyslipidemia-abnormal levels of one or more types of lipids or lipoproteins in the blood, including cholesterol and triglycerides.

New RNA therapy enhances the heart's ability to repair itself after injury

After a heart attack, cardiologists can reopen blocked vessels and restore blood flow, but the muscle cells that died will never be replaced.

Swapping red meat for plant-based meat rapidly lowers a key heart risk metabolite, trial finds

A randomized crossover trial found that replacing red meat patties with processed plant-based meat alternatives for six days significantly lowered circulating trimethylamine N-oxide (TMAO), a gut-derived metabolite linked to cardiovascular risk. The plant-based phase also produced modest reductions in cholesterol markers but slightly increased weight and NT-proBNP, possibly due to higher sodium intake.
