Balance: scales for measuring cardiovascular parameters
The technological evolution in cardiology is in great demand today, because we know that arterial hypertension is the first mortality factor in the world (WHO source). A jewel of technology that looks like a simple balance could help prevent cardiovascular disease. This scale measures heart rate, body mass index, body composition (fat, muscle, water, bone). It measures the blood flow in the foot, it calculates the time it takes the pulse wave to go from the heart to the foot. This system seems effective in preventing cardiovascular disease according to a cardiologist and researcher at the Georges Pompidou Hospital in Paris, as the measurement of the pulse wave velocity it achieves, “is an essential, most reliable measure to evaluate cardiovascular health. A validation study of the results of the connected scale is underway by comparing it with the classical medical method (the sphygmomanometer).
Another innovation: the connected stent. Its goal? Restore the circulation of clogged blood vessels. However, placement of the stent may, on the one hand, damage the endothelial cells, and, furthermore, can cause migration of the muscle cells from the wall to the stent, causing restenosis. The solution: an intelligent stent capable of communicating on the state of the vessel. It is equipped with an antenna and sensors, and a system similar to RFID (radio frequency identification device, allowing remote communication of data between a chip and a reader). The sensors allow this device to detect the different types of cells characteristics of restenosis, thrombosis and scarring; the system being connected to a reading box on the outside. It is enough for the patient to activate the system: when we pass the reader, the stent chip makes a measurement and sends the information to the box, which, via the secure Internet, transmits these data to the doctor.
Philipp Bonhoeffer’s multi-track system
When we talk about technological advances in cardiology, we often refer to Philipp Bonhoeffer, a cardiac surgeon. His investment in cardiovascular research in Africa has been successful, allowing him to develop an affordable catheter to treat mitral stenosis. Indeed, Philipp Bonhoeffer has contributed to the development of cardiology services mainly in Africa, where his technique, nowadays commonly practiced, has allowed several patients to benefit from expensive cardiac treatments. We are talking about the multi-track system, whose concept aims to use two catheters on a metal guide. Indeed, with the guide wire still in place, an angiographic catheter is advanced into the left atrium for transmural gradient measurement after dilatation. If the result is satisfactory, all the catheters can then be removed, otherwise balloons of different sizes could still be advanced on the wire. This system makes it possible to measure the transmural gradient even through a single venous approach. This is achieved by sliding two angiographic catheters along the wire which is positioned in the mitral orifice. Thus, the arterial approach commonly used for mitral dilatation can be avoided.
