Dive into the latest breakthroughs in cardiac health monitoring and care, featuring five new, cutting-edge studies from ACS journals that are reshaping our approach to heart disease.
Chocolate valentines and candies with sweet sayings shouldn't be the only hearts you think about this February. It’s also American Heart Month, which puts a spotlight on cardiovascular health. According to the American Heart Association, heart disease is the leading cause of death for Americans, so it’s important to know the status of your own heart health. New methods for cardiac monitoring can be found in these five papers recently published in ACS journals.
Revolutionizing ECG Monitoring with Self-Energized Wearable Sensors
Future electrocardiography (better known as ECG or EKG) monitoring could be done with self-powered electrodes. A study in ACS Applied Nano Materials details how a flexible heart rhythm sensor generates power from a person’s movements. Real-time heart rate and ECG signals were collected by flexible electrodes placed on a person’s chest, fingertip and wrist and transmitted wirelessly.

Accurate, Rapid Heart Failure Detection Using Quantum-Strip Sensing
Proof-of-concept test strips could identify the severity of congestive heart failure in about 30 minutes. Reporting in ACS Sensors, researchers developed paper-based strips that measure blood serum for three known markers of heart failure. When combined with a smartphone-connected reader, the method accurately indicated the cardiac disease severity of 13 out of 14 people.

A New AI-Enhanced, Eco-Friendly Monitoring Device
A soft implant to assess post-surgery heart function could dissolve in the body and avoid a follow up surgery to remove it. The flexible, biocompatible device has components that sense changes in levels of lactic acid and volatile organic compounds, as well as pH and pressure. Demonstrations on a beating, 3D-printed silicone heart model and 3D-printed cardiac tissue patches showed the device’s potential for cardiac monitoring, as published in ACS Sensors.

Real-Time Insights into Blood Analysis
Next-generation implantable “smart” stents could wirelessly monitor blood flow and blood pressure. Authors report in ACS Sensors that the technology, which opens previously obstructed arteries, self-reports an unprecedented level of information on arterial function. In a 3D-printed system mimicking the beating of a human heart, the stent relayed systolic and diastolic pressures and detected blockages occupying up to 50% of a blood vessel.

Pioneering Predictive Tools for Cardiac Arrest Treatment
Blood biomarkers could indicate brain inflammation and neuronal injury after cardiac arrest. Multiple circulating immune cells were identified as indicators from preclinical animal studies of cardiac arrest and resuscitation. Researchers say the biomarkers could be incorporated into blood tests to predict and improve neurological outcomes in cardiac arrest patients, as reported in ACS Chemical Neuroscience.
