Phidippides Cardiomyopathy
Phidippides cardiomyopathy refers to the cardiomyopathic changes that occurs after long periods of endurance training. It was named after Phidippides, the famous Greek runner who died after running from Marathon to Athens in 490 BC. It was coined by Justin E. Trivax, and Peter A. McCullough in 2012. This has been quoted in the literature multiple times and has been inaccurately thought that Dr. James O'Keefe had coined the term. He was speaking about the sudden death of Micah True, a 58-year-old ultrarunner and cult hero a.k.a. Caballo Blanco who died on a 12-mile training jog in the rugged Gila Wilderness of southwest New Mexico. After an autopsy, the Albuquerque coroner wrote that “Micah True died as a result of cardiomyopathy during exertion”. Since then, multiple websites have warned their readers on the possible damage from prolonged endurance training. The suggested etiology for Phidippides cardiomyopathy is the cardiac remodeling from prolonged strenuous exercises. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiomyopathy
Cardiomyopathy is a group of diseases that affect the heart muscle. Early on there may be few or no symptoms. As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. An irregular heart beat and fainting may occur. Those affected are at an increased risk of sudden cardiac death. Types of cardiomyopathy include hypertrophic cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular dysplasia, and Takotsubo cardiomyopathy (broken heart syndrome). In hypertrophic cardiomyopathy the heart muscle enlarges and thickens. In dilated cardiomyopathy the ventricles enlarge and weaken. In restrictive cardiomyopathy the ventricle stiffens. In many cases, the cause cannot be determined. Hypertrophic cardiomyopathy is usually inherited, whereas dilated cardiomyopathy is inherited in about one third of cases. Dilated cardiomyopathy may also result from alcohol, heavy m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endurance Training
Endurance training is the act of exercising to increase endurance. The term endurance training generally refers to training the aerobic system as opposed to the anaerobic system. The need for endurance in sports is often predicated as the need of cardiovascular and simple muscular endurance, but the issue of endurance is far more complex. Endurance can be divided into two categories including: general endurance and specific endurance. It can be shown that endurance in sport is closely tied to the execution of skill and technique. A well conditioned athlete can be defined as, the athlete who executes his or her technique consistently and effectively with the least effort. Key for measuring endurance are heart rate, power in cycling and pace in running. Endurance in sports Endurance training is essential for a variety of endurance sports. A notable example is distance running events (800 meters upwards to marathon and ultra-marathon) with the required degree of endurance trainin ...

Pheidippides
Pheidippides ( grc-gre, Φειδιππίδης, , ; "Son of Pheídippos") or Philippides (Φιλιππίδης) is the central figure in the story that inspired a modern sporting event, the marathon race. Pheidippides is said to have run from Marathon to Athens to deliver news of the victory of the battle of Marathon. The first recorded account showing a courier running from Marathon to Athens to announce victory is from within Lucian's prose on the first use of the word "joy" as a greeting in ''A Slip of the Tongue in Greeting'' (2nd century AD). The traditional story relates that Pheidippides (530–490 BC), an Athenian herald, or ''hemerodrome'' (translated as "day-runner", "courier", "professional-running courier" or "day-long runner"), was sent to Sparta to request help when the Persians landed at Marathon, Greece. He ran about in two days, and then ran back. He then ran the to the battlefield near Marathon and back to Athens to announce the Greek vict ...

Micah True
Micah True (November 10, 1953 – March 27, 2012), born Michael Randall Hickman and also known as Caballo Blanco (white horse), was an American ultrarunner from Boulder, Colorado, who received attention because of his depiction as a central character in Christopher McDougall's book ''Born to Run''. True's inclusion in the book garnered him some attention in ultrarunning circles, and some readers credited him as their inspiration for taking up the sport. During the 1980s and 90s True spent several months per year trail running in Central America. In 2003 True decided to organize a race for the Tarahumara people in Mexico that would help them preserve their culture and running heritage. True died on March 27, 2012, during a run in the Gila Wilderness, part of the Gila National Forest in southwestern New Mexico. Life Micah True was born ''Michael Randall Hickman'' in Oakland, California, the son of a World War II Marine Corps Gunnery Sergeant and the second of four children. H ...

Atrium (heart)
The atrium ( la, ātrium, , entry hall) is one of two upper chambers in the heart that receives blood from the circulatory system. The blood in the atria is pumped into the heart ventricles through the atrioventricular valves. There are two atria in the human heart – the left atrium receives blood from the pulmonary circulation, and the right atrium receives blood from the venae cavae of the systemic circulation. During the cardiac cycle the atria receive blood while relaxed in diastole, then contract in systole to move blood to the ventricles. Each atrium is roughly cube-shaped except for an ear-shaped projection called an atrial appendage, sometimes known as an auricle. All animals with a closed circulatory system have at least one atrium. The atrium was formerly called the 'auricle'. That term is still used to describe this chamber in some other animals, such as the ''Mollusca''. They have thicker muscular walls than the atria do. Structure Humans have a four-chambered ...

Ventricle (heart)
A ventricle is one of two large chambers toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle. Interventricular means between the ventricles (for example the interventricular septum), while intraventricular means within one ventricle (for example an intraventricular block). In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. Structure Ventricles have thicker walls than atria and generate higher blood pressures. The physiological load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by the atria ...

Cardiac Fibrosis
Cardiac fibrosis commonly refers to the excess deposition of extracellular matrix in the cardiac muscle, but the term may also refer to an abnormal thickening of the heart valves due to inappropriate proliferation of cardiac fibroblasts. Fibrotic cardiac muscle is stiffer and less compliant and is seen in the progression to heart failure. The description below focuses on a specific mechanism of valvular pathology but there are other causes of valve pathology and fibrosis of the cardiac muscle. Fibrocyte cells normally secrete collagen, and function to provide structural support for the heart. When over-activated this process causes thickening and fibrosis of the valve, with white tissue building up primarily on the tricuspid valve, but also occurring on the pulmonary valve. The thickening and loss of flexibility eventually may lead to valvular dysfunction and right-sided heart failure. Types Following are types of myocardial fibrosis: * Interstitial fibrosis, which is unspecific, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Arrhythmia
Arrhythmias, also known as cardiac arrhythmias, heart arrhythmias, or dysrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be lightheadedness, passing out, shortness of breath or chest pain. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death. Arrhythmias are often categorized into four groups: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias. Extra beats include premature atrial contractions, premature ventricular contractions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiac Magnetic Resonance Imaging
Cardiac magnetic resonance imaging (cardiac MRI), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. Conditions in which it is performed include congenital heart disease, cardiomyopathies and valvular heart disease, diseases of the aorta such as dissection, aneurysm and coarctation, coronary heart disease and it can be used to look at pulmonary veins. It is contraindicated if there is a permanent pacemaker or defibrillator, intracerebral clips or claustrophobia. Conventional MRI sequences are adapted for cardiac imaging by using ECG gating and high temporal resolution protocols. The development of cardiac MRI is an active field of research and continues to see a rapid expansion of new and emerging techniques. Uses Cardiovascular MRI is complementary to other imaging techniques, such as echocardiography, cardiac CT, and nuclear medicine. The technique has a ...
