High-Sensitivity Assays for Troponin in Patients with Cardiac Disease !

Troponin is a widely used biomarker in patients with cardiac disease. The use of troponin is well established in patients with suspected acute myocardial infarction (AMI), but troponin measurement is also used in other acute and nonacute settings. In patients with suspected AMI, early decision-making is crucial to allow rapid treatment and further diagnostic evaluation. Current guidelines recommend serial measurements of troponin with a cut-off concentration at the 99th percentile to triage patients in the emergency department.

Newer, high-sensitivity assays for troponin enable the detection of distinctly lower concentrations. Using these assays and very low cut-off concentrations, several rapid diagnostic strategies have been reported to improve diagnosis in acute cardiac care. Furthermore, noncoronary and non-acute applications of troponin assays — for example as a biomarker in patients with heart failure, pulmonary embolism, or stable coronary artery disease — are on the horizon and might improve individual risk stratification.

In this Review, we provide an overview on the development of high-sensitivity assays for troponin, and their application in patients with cardiac disease.

How to Perform CPR

Forget mouth-to-mouth rescue breaths. This expert-backed technique is the correct way to perform this lifesaver

Sudden cardiac arrest occurs when the heart unexpectedly stops beating, which cuts off blood flow to the brain and other organs. If not treated, it can cause death within minutes. 

In fact, only about 10 percent of people overall who experience it outside a hospital survive with their brain functions intact, a new study in JAMA found.

But early action can stave off the Grim Reaper: When sudden cardiac arrest victims first received CPR from bystanders, they were more likely to survive with favorable prognoses, the researchers discovered.

But the way you perform CPR has changed in recent years. You no longer have to put your mouth on the victim’s.
