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.

Semaglutide slows blood protein signature linked to future dementia risk

A post hoc analysis of 2,970 older SELECT participants found that semaglutide slowed worsening of a 25-protein blood signature that predicts future dementia risk. Over 104 weeks, semaglutide produced larger effects on modeled 5-year than 20-year dementia risk, but whether these biomarker changes translate into less cognitive decline or dementia remains unknown.

Scientific statement reframes cardiovascular care for older patients with cognitive impairment and frailty

Older adults with cardiovascular disease (CVD) often have coexisting cognitive impairment and frailty, conditions that can significantly affect treatment decisions, recovery, independence and quality of life and should be considered as part of an aging-informed approach to care, according to a new American College of Cardiology Scientific Statement published in JACC, the flagship journal of the ACC.

New pathway explains how zombie cells trigger chronic inflammation

Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases.

Spatial transcriptomics study elucidates cellular dynamics during heart transplant rejection

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

Tirzepatide lowers heart attack and cardiovascular event risk in adults with type 2 diabetes

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.

Explainable AI helps predict dangerous bleeding after severe heart attacks

Researchers at Indiana University School of Medicine have developed and tested a six-point scoring system that can help identify patients at high risk of internal bleeding in damaged heart muscle after a severe heart attack using explainable artificial intelligence (XAI).

Metabolic stress triggers long-lasting immune system changes in diabetes patients

A growing understanding of trained immunity, a form of long-lasting immune system adaptation, is reshaping how scientists view diabetes and its many complications.

Nicotine gum may make smokeless tobacco withdrawal easier to manage

A randomized trial found that 2 mg nicotine gum controlled craving, anxiety, and sleep problems more effectively than behavioral counselling during smokeless tobacco cessation. Although abstinence rates were numerically higher with nicotine gum, the differences were not statistically significant, highlighting the need for larger studies.

AI detects multiple heart failure types from routine ECGs

A new study led by researchers at Wake Forest University School of Medicine has found that artificial intelligence (AI) can help clinicians identify signs of heart failure, including a type that is often missed in routine care.

Nighttime light linked to conflicting signs of biological aging

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.

New review links obesity with accelerated biological aging mechanisms

The global rise in obesity and population aging represents a major public health challenge, with growing evidence suggesting that excess body fat not only increases the risk of chronic disease but may also accelerate the biological aging process.

AI sleep model reveals health risks missed by standard apnea scores

An AI foundation model extracted hidden physiological patterns from routine polysomnography and identified five patient groups with distinct long-term risks of mortality, cardiovascular disease, and neurological disorders. The approach outperformed apnea–hypopnea index severity categories for risk stratification and remained informative in an independent sleep cohort.

GLP-1 drug tirzepatide associated with lower risk of major cardiovascular events

Adding the GLP-1 receptor agonist drug tirzepatide (marketed as Mounjaro) to standard care for patients with type 2 diabetes and heart disease is associated with a lower risk of a major cardiovascular event, such as a heart attack or stroke, finds a study published by The BMJ today.

Hypothyroidism linked to higher risk of obstructive sleep apnea

According to a study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) with participants from the São Paulo Epidemiological Sleep Study (EPISONO 2018), people with hypothyroidism experience a higher frequency and severity of obstructive sleep apnea (OSA).

Global surveys reveal little progress in tobacco risk awareness over two decades

Across 46 countries, adults who smoked showed high awareness that tobacco causes lung cancer but substantially lower knowledge of cardiovascular and secondhand smoke harms. Knowledge changed little overall across two decades, supporting stronger health warnings, mass media campaigns and enforced smoke-free policies.
