Rheumatic heart disease is a type of organic heart disease caused by a hypersensitivity reaction in the body due to infection by Streptococcus pyogenes. This leads to pathological changes in the heart valves, including the tricuspid and mitral valves, resulting in stenosis or insufficiency which affects hemodynamics. This condition is known as rheumatic heart disease. Patients with rheumatic heart disease should actively seek treatment under the guidance of a doctor in the early stages to control the occurrence of complications.

How long does heart disease generally hurt?

1. Chest pain caused by angina due to coronary heart disease is located in the middle to lower third of the sternum, with unclear boundaries. It is often triggered by physical activities or emotional excitement and may radiate to the throat, lower jaw, left shoulder, and inner side of the left arm. The pain lasts for a few minutes to more than ten minutes, typically between three to five minutes, and rarely exceeds half an hour. It can be relieved by rest or by taking nitroglycerin under the tongue. The nature of the pain is feelings of stuffiness, pressure, or constriction, and may also feel like a burning sensation, but is not sharp like needle pricks or cuts. 2. The location and nature of the chest pain in acute myocardial infarction are the same as with angina, but it lasts longer, is more severe, and its triggers are less evident. It can occur even while at rest, accompanied by symptoms such as sweating, nausea, vomiting, heart palpitations, and difficulty breathing. Unlike with angina, regular rest or taking nitroglycerin under the tongue does not completely alleviate the pain.

Is hyperthyroid heart disease dangerous?

Hyperthyroidism can repeatedly cause an increase in heart rate and metabolism, which is quite active, causing a long-term overload of heart function, leading to the formation of hyperthyroid heart disease, a chronic pathological change process. In the middle and early stages, it generally does not pose a life-threatening risk, only manifesting symptoms such as palpitations, tightness after activity, breathlessness, or chest tightness, which can improve with rest. However, if hyperthyroidism is not cured for a long time, or if hyperthyroid heart disease is not treated in time, it can lead to severe heart failure. If there is a severe decline in heart pump function, causing the ejection fraction to be below 30%, it can easily cause sudden pump failure or severe arrhythmias, such as ventricular tachycardia or fibrillation, posing a life-threatening risk to the patient.

Symptoms of cor pulmonale

Cor pulmonale refers to a disease characterized by increased pulmonary vascular resistance due to pathologies of the bronchi, lung tissue, chest wall, and blood vessels of the lungs, leading to pulmonary arterial hypertension and structural and functional changes in the right ventricle. The common clinical symptoms of cor pulmonale include coughing, expectoration, shortness of breath, significant palpitations, and breathing difficulties after physical activity, reduced work capacity, and exacerbation of the above symptoms during acute infection phases. Some patients may experience chest pain and hemoptysis. The second set of symptoms relates to heart and lung function, manifesting during the decompensation phase. For instance, some patients may develop respiratory failure, and experience headaches, decreased appetite, drowsiness, significant edema in the lower extremities, and further symptoms such as arrhythmias, anorexia, abdominal distension, and nausea.

Is hyperthyroid heart disease difficult to treat?

Hyperthyroidism occurs when an excessive amount of T3 and T4 is released by the thyroid gland, leading to hyperactive metabolism throughout the body. This can cause disturbances in autonomic nervous function or receptor hyperactivity, resulting in a series of conditions related to excessive cardiac load and insufficient blood supply. Therefore, the majority of hyperthyroidism-related heart diseases improve after controlling the hyperthyroidism and are relatively easy to treat. However, if the thyroid function is not controlled repeatedly, or if the treatment is not effective, it may lead to severe enlargement of the heart and recurrent arrhythmias, making hyperthyroid heart disease difficult to cure. Nonetheless, such cases are relatively rare, with an incidence of less than 10%.

Is premature beat a type of heart disease?

Premature heartbeats belong to heart disease, and any disease that affects heart function and conduction is called heart disease. However, heart disease can be divided into organic heart disease and functional heart disease. Premature beats can also be due to different causes, categorized as physiological and pathological premature beats. Physiological premature beats are common in the normal population and are caused by disturbances in the nerves regulating the heart due to various reasons. Pathological premature beats are caused by organic heart disease, and it is necessary to treat the primary disease while correcting these premature beats.
