ARRIVE Trial: Daily Aspirin Does not Reduce Risk of First Cardiovascular Event

The role of aspirin in preventing a first heart attack or stroke among people at moderate risk of heart disease remains unclear. At the 2018 European Society of Cardiology meeting, J. Michael Gaziano presented findings from ARRIVE, a randomized, controlled clinical trial of the use of daily aspirin to prevent a first cardiovascular event among more than 12,500 participants considered to be at moderate cardiovascular risk. The team's findings are detailed in a paper published simultaneously in The Lancet.

Heart Disease Patients Understand Food Labels

According to a study, researchers estimated that many consumers have difficulty using and understanding food labels, especially men and people at risk for heart disease. Diet is considered a modifiable risk factor for heart disease prevention. In Ireland, as in many other nations, food labels provide nutritional information to help consumers make informed food choices. But this observational study identifies gaps in adults' use of food labels.

Risk Factors For Atrial Tachycardia After Heart Surgery In Infants

Researchers explored clinical and genetic factors associated with atrial tachycardia (AT) after CHD surgery in infants younger than 1-year-old. They examined variants in the genes PITX2 and IL6, which are associated with postoperative atrial fibrillation in adults after cardiac surgery.

Heartbeat Rhythm

Arrhythmias disruptions in the rhythm of the heartbeat after congenital heart disease (CHD) surgery in children are common and contribute to increased morbidity and mortality. The investigators reported in the August issue of American Heart Journal that 15% of infants enrolled in the study experienced AT after CHD surgery.

AT was associated with the need for extracorporeal membrane oxygenation (ECMO) support and longer duration of ventilation, intensive care unit stays, and hospital stays. Variations in PITX2 and IL6 were not associated with postoperative AT.

Genetic Testing Used For The Diagnosis Of Dilated Cardiomyopathy

Researchers have identified four variations in a gene known as BAG3 that are linked to a poor outcome. Genetic testing is a powerful diagnostic tool that is increasingly being used for the diagnosis of dilated cardiomyopathy, a disease in which the heart becomes enlarged, making it difficult to pump blood. Cardiomyopathy affects more than 3.5 million people in the United States.

African Americans are at especially high risk but have been underrepresented in genetic studies, often due to socioeconomic barriers and other health disparities. The study was published in the journal JAMA Cardiology, is the first to describe genetic variants that are almost exclusive to African Americans that impact the outcome in dilated cardiomyopathy patients.

Effects Of Metabolic Syndrome On Arterial Function

Scientists determined two factors of vascular aging CF-PWV and CAVI. Both of these parameters determine arterial stiffness, the main indicator of vascular aging, with high precision. However, they are influenced by age and certain metabolism abnormalities in different ways.

The study is expected to help cardiologists find effective diagnostic methods for individual patients. In young people, large vessels such as the aorta and its main branches normally have elastic walls. With aging, the walls of the arteries accumulate collagen, which increases their stiffness one of the key indicators of vascular aging.


Stiff vessel walls, unlike the elastic walls of young arteries, do not stretch and fail to slow down the flow of blood from the heart. The study was published in the Journal of Hypertension.
