One day soon mechanical hearts could replace our flesh and blood ones

One day soon mechanical hearts could replace our flesh and blood ones

Back in 1982, Barney Clark became the first person to live without a human heartbeat when he had the Jarvik 7 artificial heart implanted in his chest. Since then, thousands of others have joined him, but none have been able to permanently live with an artificial heart. But someday (possibly soon), science will develop artificial hearts that beat as well as our own flesh-and-blood ones, according t... »

The Human Heart Begins Beating Just 16 Days After Conception

The Human Heart Begins Beating Just 16 Days After Conception

Our hearts beat roughly three billion times throughout our lives, but it is not entirely clear when this biological percussion begins. Previous research has suggested that it happens on the 21st day of a pregnancy, but a new eLife study by the University of Oxford has concluded that it’s in fact as early as 16 days post-conception. Directly imaging the moment a human embryo activates its cardiovas... »

This Man Lived Without His Heart For Over A Year

This Man Lived Without His Heart For Over A Year

It’s been nearly 50 years since the first heart transplant and still today these surgeries remain one of the most impressive feats of biomedical science. As truly life-saving as this procedure can be, people often have to wait for months and years to be matched with a compatible donor. However, help is on hand for those stuck on endless waiting lists, in the form of total artificial hearts. Stan L... »

Baboon With Transplanted Pig Heart Survives For Nearly Three Years

Baboon With Transplanted Pig Heart Survives For Nearly Three Years

Scientists have managed to keep a pig heart transplanted into a baboon beating for almost three years, setting a new record and pushing forward the field of cross-species transplantation. The study, from the National Institute of Health, is the result of around 10 years of research into whether or not organs from one species could be transplanted into another. The study on a handful of primates ha... »

All about MYOCARDIAL INFARCTION (heart attack)

Myocardial infarction, commonly known as a heart attack, is the irreversible necrosis of secondary to prolonged ischemia. This usually results from an imbalance in oxygen supply and demand, which is most often caused by plque ruptre with thrombus formation in a cornary vessel, resulting in an acute reduction of blood supply to a prtion of the myocardium. RISK FACTORS: Modifiable: Hyperlipidemia Hi... »

Endocarditis

Endocarditis

Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves. Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices. Endocarditis is characterized by lesions, known as vegetations, which is a mass of platelets, fibrin, microcolonies of... »

Heart transplantation

Heart transplantation

A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure or severe coronary artery disease. As of 2008 the most common procedure is to take a working heart from a recently deceased organ donor (cadaveric allograft) and implant it into the patient. The patient’s own heart is either removed (orthotopic procedure) or, les... »

Constrictive pericarditis

Constrictive pericarditis

Constrictive pericarditis Abnormal thickening of the pericardial sac (constrictive pericarditis) can compress the heart, impairing heart function and resulting in heart failure. The diagnosis is made by inspecting the jugular venous pulse in the neck. In normal individuals, the jugular venous pulse drops on inspiration.I In patients with constrictive pericarditis, the reverse happens and this is c... »
