Dr. David Pollock has a simple message for fellow hypertension researchers: think endothelin. In a country where better than 30 percent of adults have high blood pressure and 50-75 percent of those have salt-sensitive hypertension, he believes the powerful endothelin system, which helps the body eliminate salt, should not be essentially ignored. However, the research and clinical world focus on suppressing a better-known system, which prompts the body to hold onto salt, said Pollock,...

Taking Pulse From The Finger Can Show Aorta Stiffness
2013-09-05 17:09:25

Enid Burns for redOrbit.com – Your Universe Online An academic from the University of Iowa has developed a new, simpler method to measure the stiffness of the aorta, a common risk factor of heart disease. The new method uses an instrument called a transducer on the finger, or over the brachial artery just inside the arm beneath the elbow. Measuring the pulse, combined with factors, including a person's age and body mass index, enables the doctor to determine whether the aorta has...

Diagnosing Heart Disease With Video Of Head Movements
2013-06-20 13:23:45

Lee Rannals for redOrbit.com — Your Universe Online A new way to diagnose cardiac disease by analyzing miniature head movements with digital video is being developed. MIT researchers have created an algorithm that can accurately measure the heart rates of people through digital video by analyzing imperceptibly small head movements from the rush of blood caused by the heart's contractions. This algorithm was able to give pulse measurements that were consistently within a few beats per...

[WATCH VIDEO: Stanford's Wearable Heart Monitor] Lee Rannals for redOrbit.com — Your Universe Online A team from Stanford University writing in the journal Nature Communications say they have developed a wearable heart monitor that is thinner than a dollar bill. The engineers combined layers of flexible materials into pressure sensors to create the new skin-like heart monitor. They said their device could be used to continuously track heart health and provide doctors with a...

Even Fit People At Higher Death Risk With High Heart Rates
2013-04-16 21:14:35

Brett Smith for redOrbit.com — Your Universe Online According to a new study published in the journal Heart, a higher resting heart rate could be a greater risk indicator than a person´s overall fitness. While physically fit individuals tend to have lower at-rest heart rates, researchers at the University of Copenhagen wanted to see if heart rate itself had any indication of an individual's risk of death, regardless of their fitness capacity. "A high heart rate does not...

The heart is a part of the circulatory system, and is considered one of the most vital organs of the human body. It is about the size of a fist, has a mass of approximately 300 grams, and its main function is to contract and produce enough pressure to circulate blood throughout the body. The top of the heart where the veins and arteries all connect is called the base. The pointed lower tip of the heart is called the apex. The coronary sulcus is a deep groove that runs horizontally across the...
