New Research Visualizes Cardiac Blood Flow

New research shows the relationship between hydraulic forces and cardiac blood flow

Researchers have discovered that the ventricles of the heart are filled with the help of hydraulic forces, similar to those used in hydraulic brakes in vehicles and other mechanical devices

Until today, blood flow mechanics during diastole have only been partially understood. The new discovery suggests that hydraulic forces, together with the heart muscle protein titin both help fill the ventricles with blood. Hydraulic forces are the pressure that liquids exert on an area. The forces are affected by blood pressure in the heart, as well as the difference in size between the ventricles and the atria. The hydraulic forces that were found to exist are a result of the fact that the ventricle is larger than the atrium

The discovery was made by researchers at the Karolinska Institutet, and the KTH Royal Institute of Technology and was published online, in the March 3, 2017, issue of the journal Nature Scientific Reports. The researchers enlisted healthy participants for the study, and used Cardiovascular Magnetic Resonance (CMR) imaging to measure the size of both heart chambers during the diastole phase. The results showed that the atrium was effectively smaller during the filling process. According to the researchers, it is import to measure both the atrium and ventricle, and look at their relative dimensions during heart failure, rather than focusing only on the size of the ventricles

Dr. Martin Ugander, physician and associate professor at the Karolinska Institutet, said, "Although this might seem simple and obvious, the impact of the hydraulic force on the heart's filling pattern has been overlooked. Our observation is exciting since it can lead to new types of therapies for heart failure involving trying to reduce the size of the atrium

Red blood cells contain hemoglobin, which is reddened by oxygen saturation. Its main function is to transfer oxygen from the lungs to all cells of the body to carry out the cellular respiration necessary to produce energy. Blood is more viscous than water 5 times, and its density is 1.55-1.65 g / cm,, and its functions are many. It is very important. It is the transport material in the body. It transfers oxygen, carbon dioxide, hormones, etc., Regulates body temperature. The blood in the normal human body is 5 liters when the body is 70 kg

The heart is the most important member of the blood circulation and its main axis, without which blood will not circulate in the body. The size of the heart muscle is the size of the hand grip, which pumps 2000 gallons of blood every day through 100 thousand contractions and diuresis every day, and protects this important muscle and sensitive chest . The left ventricle, left and right, separates the left and right segments of the wall. The upper sections, called the atrium and the lower one, are called the ventricle, and are connected by different arteries and veins such as the coronary artery, the aorta, veins and arteries Pneumonia, upper vena cava, inferior vena cava, regulate blood entry and exit valves such as aortic valve, pulmonary valve
