Which department should I register for cardiomyopathy?
Cardiomyopathy is a common disease in our daily lives, characterized primarily by changes in the myocardium. After being diagnosed with cardiomyopathy, many patients often ask which department they should register with at the hospital. Generally speaking, cardiomyopathy falls under cardiovascular diseases, so registration should be with the department of cardiology. Cardiologists often prescribe a cardiac echocardiogram to diagnose myocardial diseases. Conditions such as hypertrophic cardiomyopathy or dilated cardiomyopathy require a cardiac echocardiogram for detection, which is the most commonly used examination for cardiomyopathy.
Can an 8mm ventricular septal defect heal by itself?
The ventricular septal defect is 8 millimeters, which is considered a medium-sized defect. This type of defect is relatively large and will not heal on its own. Moreover, this ventricular septal defect requires timely surgical treatment, and close observation is needed in daily life. If the child is prone to catching colds, leading to repeated pneumonia, then prompt surgical treatment is necessary without delay. If the child's growth and development are not affected and there are no repeated incidents of pneumonia, close monitoring can be considered. Surgery to repair the ventricular septal defect can be considered after the child reaches two years of age. Otherwise, if delayed, it may lead to heart failure and complications such as pulmonary hypertension, severely affecting the quality of life and endangering the patient's safety.
Can atrial fibrillation be cured?
Atrial fibrillation is a common arrhythmia in daily life. Many patients often ask their doctors after being diagnosed with atrial fibrillation, "Can my atrial fibrillation be cured?" The answer is affirmative. With the advancement of medical technology, some patients can be completely cured of atrial fibrillation, which needs to be analyzed and judged based on the treatment methods for atrial fibrillation. First, medication treatment, which is currently the mainstream method for treating atrial fibrillation. Most patients use medication treatment, but it cannot effectively cure atrial fibrillation. Second, radiofrequency ablation treatment, which is a minimally invasive means of treating atrial fibrillation. This technology has become very mature, and many patients have achieved complete cure of atrial fibrillation through radiofrequency ablation treatment. Third, surgical treatment, where a portion of the patients undergo a Maze procedure during surgery, which can also achieve the purpose of curing atrial fibrillation.
What diseases are characterized by tachycardia?
Tachycardia refers to a phenomenon where the heart rate exceeds 100 beats per minute. There are many diseases that can cause tachycardia, with the most common ones including: First, heart diseases such as congenital heart disease, cardiomyopathy, and coronary artery disease can lead to heart failure, often resulting in tachycardia; Second, respiratory diseases, such as chronic obstructive pulmonary disease (COPD) or cor pulmonale, can also lead to tachycardia due to long-term oxygen deficiency; Third, endocrine disorders, such as hyperthyroidism, often cause tachycardia; Fourth, hematological disorders, such as severe anemia, often lead to tachycardia as well; Additionally, fever can also cause tachycardia.
Is tachycardia related to being overweight?
Tachycardia generally has no relation to obesity. Clinically, tachycardia can be categorized into sinus tachycardia, paroxysmal supraventricular tachycardia, ventricular tachycardia, and other types, none of which have a definitive relation to obesity. There are many causes of tachycardia, such as fever, hyperthyroidism, and anemia. Additionally, certain structural heart diseases and pulmonary diseases can also lead to tachycardia. While obesity itself introduces a range of issues like hyperlipidemia, diabetes, and other metabolic abnormalities, which might affect the heart rate, this impact is usually not severe.
Why does mitral valve regurgitation cause left ventricular hypertrophy?
Mitral valve insufficiency leads to left ventricular hypertrophy. This occurs because when the mitral valve does not close fully, the contraction of the ventricles often causes the blood in the left ventricle to flow back into the left atrium, resulting in a significant increase in the blood volume of the left atrium. When the ventricles relax the next time, the left ventricle receives a large amount of blood from the left atrium, as well as the remaining original blood. This causes a significant increase in the capacity and load of the left ventricle, and over time leads to enlargement and hypertrophy of the left ventricle. This condition eventually leads to the appearance of symptoms of heart failure, causing the patient to repeatedly experience difficulty in breathing.
The harms of pulmonary arterial hypertension during pregnancy
Pulmonary hypertension is categorized into mild, moderate, and severe stages. If it is mild pulmonary hypertension, pregnancy generally does not have a major impact. However, for those with moderate or especially severe pulmonary hypertension, pregnancy can be very dangerous for both the mother and the fetus. As the fetus grows, pulmonary hypertension can lead to ischemia and hypoxia, which can worsen over time. The mother is likely to develop symptoms of acute heart failure, severely endangering her life. Additionally, it can cause intrauterine hypoxia for the fetus, leading to miscarriage or stillbirth. Therefore, pregnancy is not recommended for patients with moderate, and particularly severe, pulmonary hypertension.
Is a 12mm atrial septal defect serious?
Atrial septal defect (ASD) is a fairly common congenital heart disease in pediatric cardiology. For infants and young children, atrial septal defects can be categorized based on their size into three types: A large atrial septal defect typically refers to a defect larger than 10 millimeters. A medium atrial septal defect generally refers to a defect that ranges from 5 to 10 millimeters. A small atrial septal defect usually refers to a defect that is less than 5 millimeters. Therefore, for an infant or young child, an atrial septal defect measuring 12 millimeters would indeed be considered quite severe.
How is myocardial infarction treated?
Myocardial infarction is a relatively common critical illness in our daily lives. Many patients often delay their condition severely due to untimely treatment, which becomes an important cause of disability and death. So how should myocardial infarction be treated? It should be treated from the following two aspects: First, acute myocardial infarction. For acute myocardial infarction, it is necessary to promptly open the occluded blood vessels, restore cardiac perfusion, and save viable myocardium. This can be achieved through emergency interventional treatment or thrombolytic therapy. Second, old myocardial infarction. At this time, treatment mainly involves taking oral aspirin and statins to stabilize the disease and prevent the condition from worsening or deteriorating. (Medication should be used under the guidance of a professional doctor.)
Early symptoms of arteriosclerosis
Arteriosclerosis often has many symptoms, which mainly depend on the location of the arteriosclerosis. For example, patients with cerebral arteriosclerosis often experience dizziness, headaches, or confusion, If it is coronary arteriosclerosis, it often causes symptoms of chest tightness or shortness of breath in patients, which tend to be more obvious or worsen after activity, If it is lower limb arteriosclerosis, it often causes pain when walking, which can disappear or significantly reduce after rest.
