Reportedly, the AEDs (automated external defibrillators) are mostly placed in areas of low menace and might be not available during some times of the day. Finding out the most favorable location for AEDs could induce increased defibrillation by bystanders and surge survival rate in those experiencing OHCA (out-of-hospital cardiac arrest), as per to research published in the Journal of the American College of Cardiology. The utilization of publicly accessible AEDs is linked with considerably better results in patients encountering OHCA providing they are accessible during a time of need.
The researchers utilized computer prototypes to find out the optimal position of AEDs in Copenhagen. This computer-simulated (in silico) test imitated an RCT (randomized clinical trial). This study design is fast and cost-effective whilst also facilitating for scientists to carry out research for longer spans of time and to integrate a control that may not otherwise be achievable. By using historical information, they were able to verify locations where OHCAs were more possible to occur and correlated them against real AED operations. The study also included OHCAs that happened in public locations. Timothy C.Y. Chan—Director of the CHE (Centre for Healthcare Engineering) at the University of Toronto—said, “Our trial design insured that the optimization ways were not advantaged in comparison to the real AED placements.”
On a similar note, recently, a study showed that early life environment might cause high blood pressure in children. The place a mother resides and the temperature outside when she is pregnant, along with other environmental aspects, can affect whether her child is hypertensive or prehypertensive during childhood, as per to a study. The study was published in the Journal of the American College of Cardiology. The exposure to negative lifestyle elements in pregnancy, such as physical inactivity, obesity, alcohol or tobacco consumption, and poor diet have stated as heart disease peril factors for mothers.
