#Heart

A new metric that blends steps with resting heart rate from smartwatches could improve how we monitor heart health. Researchers from a leading U.S. medical school studied the concept, publishing in a prominent cardiac journal, and introduced the daily heart rate per step (DHRPS). This simple ratio divides average resting heart rate by average daily steps to reflect heart efficiency.

The relevance is clear: heart inefficiency is linked to conditions such as Type 2 diabetes, high blood pressure, heart failure, stroke, and coronary disease. If Thai residents adopt this easy calculation alongside existing routines, personal health management could improve and potentially ease the burden on the healthcare system. The growing use of wearables in Thai cities makes this a timely addition to current wellness practices.

A breakthrough in bioelectronics offers a glimpse of a less invasive future for treating congenital heart defects in infants. Researchers have developed the world’s smallest injectable pacemaker that powers itself from the body’s fluids and dissolves after temporary use, reducing the need for open-heart procedures.

The ultra-miniature device is designed to be injected via syringe and works with a soft, chest-worn monitor. The monitor detects irregular heart rhythms and activates the pacemaker through the skin with a light pulse. This approach aims to simplify care while protecting the health of young patients.
