RAHAT medical project launched in Rajasthan

Rajasthan Chief Minister Vasundhara Raje inaugurated a medical project Rajasthan Heart Attack Treatment programme (RAHAT) to provide people timely treatment during heart attacks in remote and rural areas.

She also flagged off RAHAT ambulance fitted with equipment and trained paramedical staff required for treatment of heart disease. With this, Rajasthan became the second state in the country after Tamil Nadu to launch health programme against Heart Diseases.

Key Facts
  • RAHAT project was launched by Eternal Heart Care Centre Hospital, a private hospital based in capital city Jaipur.
  • It will provide emergency ambulance service and telemedicine service to the patients facing heart attack through the hospitals.
  • The project is a ST-Elevation Myocardial Infarction (STEMI), a very serious type of heart attack, management telemedicines platform.
  • It can capture and transmit patient’s EKG (electrocardiogram) along with clinical history from remote geographical locations to heart command centre hub.
  • It will provide patient basic treatment in the ambulance on the way to the nearest Heart Hospital through telemedicine with help of team of expert cardiologists.

Scientists develops first Biological Pacemaker using Human Stem Cells 

Scientists from Canada have developed the first functional pacemaker cells using human pluripotent stem cells. 

The cells can regulate heart beats with electrical impulses. It paves the way for alternate biological pacemaker therapy.

Key Facts 
  • Pluripotent stem cells have the potential to differentiate into more than 200 different cell types that make up every tissue and organ in the body.
  • These cells can be coaxed in 21 days to develop into pacemaker cells. For this purpose researchers had used developmental-biology approach to establish a specific protocol for generating pacemaker cells.
  • These human pacemaker cells were tested in rat hearts and have shown to function as a biological pacemaker, by activating the electrical impulses that trigger the contraction of the heart.
Significance of this research
  • Learning how to generate pacemaker cells could help in understanding disorders in pacemaker cells, and provide a cell source for developing a biological pacemaker.
  • Biological pacemakers offers promising alternative to electronic pacemakers and overcome their drawbacks as a lack of hormonal responsiveness and t inability to adapt to changes in heart size in pediatric patients.
Comment

In general Sinoatrial node pacemaker cells are the primary pacemaker of the heart that controls the heartbeat throughout life. Defects in these pacemaker cells can lead to heart rhythm disorders that are commonly treated by implantation of electronic pacemaker devices. A pacemaker is a device which is placed in the chest or abdomen to help control abnormal heartbeats using low-energy electrical impulses.
