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.

Increased epicardial fat volume linked to greater myocardial injury after infarction

Increased volume of epicardial adipose tissue, detected by cardiovascular imaging, was found to be associated with greater myocardial injury after a myocardial infarction.

AI-based tool may help personalize the treatment of patients with reduced coronary blood flow

Reduced coronary blood flow, measured with an artificial intelligence-based imaging tool, predicted future cardiovascular events in patients with suspected stable coronary artery disease.

Family history of cardiometabolic disease linked to early heart damage in adolescents

A new study among more than 1,500 British adolescents is the first in the world to assess the association between familial cardiometabolic diseases and the offspring's risk of premature heart damage by early adulthood.

Study reveals the hidden toll of sudden cardiac death in type 1 and type 2 diabetes

A Danish nationwide study found that people with type 1 and type 2 diabetes have markedly higher rates of sudden cardiac death than the general population, especially at younger ages. At age 30, people with diabetes lose many years of life, with several of those years specifically attributable to sudden cardiac death.

NeuMap unveils the hidden architecture and life-long patterns of human neutrophils

Neutrophils are the most abundant immune cells in the body and the first to respond to infection or tissue damage.

Study highlights limitations of current cardiac screening tools

Current cardiac screening tools used to prevent heart attacks fail to identify nearly half of the people who are actually at risk of having one, according to a new study led by Mount Sinai researchers.

Study compares GLP-1 drug benefits and finds substantial variation in clinical effects

GLP-1 receptor agonists improve glycaemic control and provide renal, metabolic, and selective cardiovascular benefits in people with type 2 diabetes, based on an umbrella review of 17 meta-analyses. However, these agents consistently increase gastrointestinal adverse effects and show important distinctions between class-level outcomes and individual drug effects, particularly for semaglutide.

New patch may help heal the heart after a heart attack

A new patch developed by Texas A&M University researcher Dr. Ke Huang may offer a way to help the heart heal after a heart attack.

Study links obesity severity to escalating cardiometabolic and renal disease burden

Obesity severity is incrementally associated with a broad range of cardiometabolic and renal disease burden, as discovered by researchers at Pennington Biomedical Research Center. Recently published in Obesity, the paper "Association of Obesity Severity with Cardiometabolic and Renal Disease Burden in the United States," explored the relationship through a cross-sectional study of data from the U.S. Behavioral Risk Factor Surveillance System survey.

Cardiologists recommend reassessing need for additional stents later

A blocked coronary artery causing an acute heart attack must be opened immediately with a stent procedure. However, if other coronary arteries also appear to be narrowed, it is safe to wait and treat those later. This approach cuts the number of stent procedures in half, according to cardiologists from Radboud university medical center, writing in The New England Journal of Medicine.

Evolocumab shows clear benefit in preventing first-time heart attacks and strokes

Adding the PCSK9 inhibitor evolocumab to standard lipid-lowering therapy significantly reduced first major cardiovascular events in adults with atherosclerosis or high-risk diabetes who had never had a heart attack or stroke. The 4.6-year study confirmed durable safety and benefit, supporting earlier, more intensive LDL cholesterol control.

New data supports earlier use of evolocumab in high-risk diabetes

Adding the PCSK9 inhibitor evolocumab to a high-intensity, cholesterol-lowering regimen reduced the risk of a first major cardiovascular event among adults with atherosclerotic cardiovascular disease (ASCVD) or diabetes , according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

MRI-based blood flow testing offers better answers for unexplained chest pain

Chest pain may still be angina even when coronary angiogram testing shows the main heart arteries look clear. Using stress cardiac stress MRI testing to measure blood flow around the heart appears to improve diagnosis and patient quality of life.

Diabetes drugs semaglutide and tirzepatide show real-world heart benefits

In a large real-world analysis across three U.S. healthcare databases, semaglutide and tirzepatide showed cardiovascular benefits consistent with randomized trials. Semaglutide lowered heart attack and stroke risk versus sitagliptin, while tirzepatide performed comparably to dulaglutide and semaglutide over one year.

Study reveals double trouble for peripheral arterial disease patients with AFib

New research from Intermountain Health in Salt Lake City finds that patients diagnosed with peripheral arterial disease (PAD) who also have atrial fibrillation (AFib) face a significantly higher risk of major adverse cardiovascular events (MACE).

Beta-blockers offer no clinical benefit for myocardial infarction survivors with preserved cardiac function

A major analysis led by the Centro Nacional de Investigaciones Cardiovasculares (CNIC), in collaboration with international institutions, has pooled data from 17,801 myocardial infarction survivors with preserved cardiac function enrolled in five global clinical trials.

Complete revascularization reduces the risk of death from cardiovascular causes

Opening all blocked arteries with stents in patients with a heart attack, known as complete revascularization, reduces the risk of death from cardiovascular causes, death from any cause and future heart attacks compared with opening only culprit artery causing the heart attack according to a new, large international study led by researchers at the Population Health Research Institute (PHRI), a joint organization of McMaster University and Hamilton Health Sciences.

Mayo Clinic scientists create stem cell patch to heal hearts without surgery

Mayo Clinic researchers have developed a pioneering method to mend damaged hearts without open-heart surgery, an advance that could one day transform the treatment of heart failure.

Action needed to fix gender gap in cardiac rehab

Addressing barriers to cardiac rehab for women is essential. The AHA's guidelines focus on enhancing access and promoting effective heart health strategies.
