Institute of Physics An implantable device that reduces blood pressure by sending electrical signals to the brain has been created by a group of researchers in Germany. The device has successfully reduced the blood pressure in rats by 40 per cent without any major side effects, and could offer hope for a significant proportion of patients worldwide who do not respond to existing medical treatment for the condition. The first results have been published today, 9 May, in IOP...

American Heart Association Rapid Access Journal Report Maintaining or boosting your physical activity after age 65 can improve your heart's electrical well-being and lower your risk of heart attack, according to a study in the American Heart Association journal Circulation. In heart monitor recordings taken over five years, researchers found that people who walked more and faster and had more physically active leisure time had fewer irregular heart rhythms and greater heart rate...

University of Pennsylvania School of Medicine Using a University of Pennsylvania-designed device to noninvasively and continuously monitor cerebral blood flow (CBF) in acute stroke patients, researchers from Penn Medicine and the Department of Physics & Astronomy in Penn Arts and Sciences are now learning how head of bed (HOB) positioning affects blood flow reaching the brain. Most patients admitted to the hospital with an acute stroke are kept flat for at least 24 hours in an effort...

Researchers at Tokyo Institute of Technology identify links between the palatability of various tastes and circulation in different parts of the face. Tastes deemed 'pleasant' increase blood flow in the eyelid according to a recent study by Hideaki Kashima, Yuka Hamada and Naoyuki Hayashi from the Prefectural University of Hiroshima, Kyushu University and Tokyo Institute of Technology. The research identifies links between the subjective perception of palatability with circulatory...

Intravenous/sublingual tissue-penetrating homing peptide enhances activity of other pulmonary drugs, according to new research published in the American Journal of Pathology The development of new, more effective vasodilators to treat pulmonary arterial hypertension (PAH) has been hampered because of their systemic toxicity and adverse side effects. An international team of investigators seeking to surmount these problems and increase drug efficacy have determined that a vascular homing...

Rise does not seem to be linked to overall weight gain; implications for future cardiovascular health The resting pulse rate of UK pre-teens may have risen by up to two beats a minute during the past 30 years. But the rise does not seem to be linked to the overall weight gain seen in this age group during this period, reveals research published online in the Archives of Disease in Childhood. While this rise may seem modest, resting pulse rate is a proxy for general physical fitness and...

People in middle age who have a high blood pressure measure called pulse pressure are more likely to have biomarkers of Alzheimer's disease in their spinal fluid than those with lower pulse pressure, according to research published in the November 13, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Pulse pressure is the systolic pressure, or the top number in a blood pressure reading, minus the diastolic, or the bottom number. Pulse pressure...

Heart
2013-01-01 11:25:12

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...
