How to Clean a medications to hold before cardiac cath|cardiac Catheterization Site Cardiac catheterization is a common medical procedure which enables your doctor to examine your heart. A small tube is inserted through a blood vessel in your leg or arm and moved through your body until it reaches your heart. The catheter may be used to check the blood pressure in your heart, put contrast dye into your heart to facilitate taking X-rays, take blood samples, biopsy your heart, or check for structural problems with the chambers or valves. Because it is an invasive procedure, minimizing infection risk before and after the procedure is very important 1 Avoid people who are sick. If you are sick, even with a minor illness like a cold or flu, this burdens your immune system and makes it easier for you to develop complications. If you wake up the morning of your procedure with a fever, cough, drippy nose, or any other symptoms, notify your doctor immediately.[12] Wash your hands after you shake hands with people and before you eat. This will reduce the likelihood that you expose yourself to pathogens carried by others. Don’t go near, hug, or shake hands with people who have the flu or a cold. Avoid being in small confined spaces with lots of people. These are excellent opportunities for pathogen exchange. This may mean not taking public transportation such as the bus or subway. 2 Boost your immune system by managing stress. Stress causes hormonal and physiological changes in your body which, over time, can weaken your immune system. By easing stress and anxiety before the procedure, you can help ensure that your immune system will remain strong. You can reduce stress by: Learning as much as possible about your procedure. Your doctor and the hospital can provide you with information. Many hospitals even have booklets of information that they provide and make freely available online. Ask your doctor or hospital if such information is available. If so, it will help you under

How to Cope with a Heart Murmur|Cardiovascular System Health A normal, working heart beats at around 100,000 beats each day. Using a stethoscope, your doctor should hear a steady “lub-Dub...lub-Dub” from your heart. A heart murmur refers to abnormal heart sounds that are heard along with a normal heartbeat, such as a faint or loud swishing sound. Heart murmurs are classified into two types: innocent or “harmless” and abnormal. Innocent heart murmurs are not considered serious medical issues, but abnormal heart murmurs must be addressed, treated, and monitored. 1 Understand how your heart works. Your heart consists of four chambers and four valves. The two upper chambers are called atria and the lower chambers are called ventricles. The right atrium collects the non oxygenated blood from the superior and inferior vena cava (two large veins) and pours the blood into the right ventricle through the Tricuspid valve. The right ventricle then pushes the non oxygenated blood to the pulmonary artery where the blood moves into the lungs through the Pulmonary valve. After making this gas exchange, the oxygenated blood returns back to the heart to the left atrium, which then transfers it to the left ventricle through the Mitral valve. The left ventricle then pushes the oxygenated blood to the aorta artery and the blood moves to different body organs through the Aortic valve. 2 Imagine heart valves like doors or gates in your heart. They allow blood to be transferred in only one direction, preventing it from returning backward through any valves. The “lub-Dub” sound comes from the heart valves opening and closing. When the two ventricles squeeze to contract, the Tricuspid and Mitral valves are both closed to allow the blood to enter into the pulmonary and aorta arteries respectively, and not to return back to the atriums. This process is called the “Systole” and is heard as the first “lub” sound in your heart beat. When the two atriums squeeze to contract, the two ventricles

How to Find the Cause of Aortic Regurgitation|bicuspid aortic valve chest pain Aortic regurgitation is when there is damage to the aortic valve, causing blood to leak backwards from the aorta (the body's largest blood vessel) back into the heart after each heartbeat. There are a number of things that can cause aortic regurgitation, including infection, trauma, rheumatic heart disease, aneurysm, and congenital and hereditary causes. The main way to determine the cause of aortic regurgitation is through cardiac imaging. Other medical tests may also be ordered to confirm the underlying cause of aortic regurgitation as well as assess overall cardiac health. 1 Receive a transthoracic echocardiogram. A transthoracic echocardiogram (commonly called an "echo") is usually the first specific investigation to look at the function of the aortic valve. It uses ultrasound waves to create an image of the heart as it functions in real time. It shows each heartbeat, and can assess blood flow through the various chambers of the heart with each heartbeat.[8] An echo can also be used to determine the underlying cause of aortic regurgitation. 2 Have a transesophageal echocardiogram. If a transthoracic echocardiogram is insufficient to determine the underlying cause of aortic regurgitation, the next step is to proceed to a transesophageal echocardiogram. This is when, rather than having the test performed from outside your chest, an ultrasound probe is instead inserted down your esophagus to provide a more close-up and detailed view of your heart, 3 Obtain other diagnostic tests as needed. Depending upon what is suspected as the underlying cause of aortic regurgitation, additional investigations may be ordered to provide more information. For instance, if an infection of the heart valve is suspected, blood tests and a blood culture will likely be ordered to test for the presence of bacteria. If trauma is suspected, a chest x-ray or CT scan will likely be needed to evaluate for injury

How to Recognize a mitral regurgitation medication|Leaking Heart Valve The heart valves enable your blood to pass between the different chambers of your heart. When they leak it is called regurgitation. This happens when blood flows back into the chamber it came from as the valve is closing or if the valve does not close completely. This can occur in any of the heart valves. Because leaks make the heart less efficient at pumping blood, they force the heart to work harder to pump the same amount of blood. Treatment may include medications or surgery, depending on the cause of the leak and its severity 1 Reduce your salt intake. A low-salt diet can help lower your blood pressure, which will in turn reduce the strain on your heart. It will not repair a defective valve, but it can reduce the likelihood that it will get worse. Even if surgery isn’t necessary for you, your doctor may still recommend you eat a low-salt diet.

HPHT diamonds/CVD diamonds Diamonds square measure pure carbon. Ever since this was discovered in 1797, many of us have tried to provide diamonds unnaturally however the important breakthrough came in 1955, once General electrical managed to provide a workplace big diamond employing a revolutionary Super Pressure Project that helps to provide diamonds. Ever since there has been a gradual growth within the production of workplace big diamonds, ninetieth of that have industrial uses. Currently, diamonds square measure made mistreatment 2 techniques- HPHT and CVD diamonds HPHT diamonds The air mass warmth method imitates the means diamonds square measure fashioned naturally. A carbon ‘seed’ is place in a very specially designed press wherever it's given air mass and a warmth of regarding 1400 Degrees stargazer is employed to create colourless and prime quality diamonds which may then be used for industrial use and also the jewelry trade. Currently there square measure 3 main ways in which HPHT diamonds square measure made- • The Belt Press • The boxy Press • The BARS equipment Of these, the Russian designed BARS equipment is that the most well liked. It consists of a ceramic cylindrical ‘synthesis capsule’ that is placed in eight steel anvils. the complete equipment is then secured and oil is additional that is heated, giving pressure that ultimately leads into the creation of a diamond. CVD diamonds Chemical Vapour Deposition diamonds don't need pressue, in contrast to HPHT diamonds. this technique was developed within the Nineteen Eighties. This method involves the heating of a mix of organic compound gas (generally methane) and chemical element in a very chamber at extreme low pressures. This leads to the formation of diamonds that square measure freed from any chemical inclusions or alternative impurities. These technologies square measure serving to the introduction of workplace big diamonds to the jewelry and alternative allied industries that historically use
