What is often referred to as tapping heart flop is medically known as Keshan disease. One of the causes of Crohn’s disease is environmental factors, as a lack of such elements as iodine and selenium, which are needed by the body, prevents a part of the heart muscle from functioning, causing damage and leading to the onset of the disease. Daily life with insufficient intake of vitamins or nutrients in the body, especially those who consume too much salt and tend to be picky eaters, often leads to Crohn’s disease. Not only the environment but also the seasons. Acute Creutzfeldt-Jakob disease occurs most often in winter especially in people who do not pay attention to keeping warm, or in people who are overworked or have irregularities in their daily lives. Subacute cases are more common in the spring and summer, especially in children who lack exercise and have poor body resistance. There are also viral infections, such as coxsackie virus and even upper respiratory tract and lung infections, which cause myocarditis and thus trigger Keshan disease.
