Cardiac Arrest

A cardiac arrest, also known as cardiopulmonary arrest or circulatory arrest, is the abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole.

What is Cardiac Arrest?

A cardiac arrest is also called a cardiopulmonary arrest or circulatory arrest and indicates a sudden stop in effective and normal blood circulation due to failure of the heart to pump blood.

Early heart pump use improves survival in patients experiencing cardiogenic shock

Findings from the Can Escalation Reduce Acute Myocardial Infarction Mortality in Cardiogenic Shock (CERAMICS) registry demonstrate that early use of a small heart pump improves outcomes in patients experiencing a severe form of heart failure called cardiogenic shock after suffering from a heart attack and undergoing a stenting procedure.

Study finds a clear link between ultraprocessed food and heart disease risk

A prospective analysis of 6,531 adults in the multiethnic MESA cohort found that higher ultraprocessed food intake was associated with a graded increase in incident ASCVD risk, with each additional daily serving linked to about a 5% higher risk. The association was stronger in Black participants, while no significant interaction was seen by sex or income.
