Can heart disease be inherited?
Whether heart disease is hereditary depends on the specific type of heart disease. Some heart conditions are hereditary diseases, such as hypertrophic cardiomyopathy, which is an autosomal dominant inherited disease and can be inherited. Some heart diseases are related to genetics, such as coronary heart disease and dilated cardiomyopathy. These genetically related diseases significantly increase the risk of their offspring developing these conditions, but it does not necessarily mean that they will develop the disease, as environmental factors also play a crucial role. Of course, some heart diseases are not genetic, such as most congenital heart diseases, heart valve diseases, infective endocarditis, and myocarditis, which are not related to genetics.
Symptoms of pulmonary hypertension include:
The clinical symptoms of pulmonary hypertension primarily include: 1. Shortness of breath, which is the most common symptom of pulmonary hypertension. Many patients experience shortness of breath as their initial symptom, which is often related to physical activity. As the condition progresses, the shortness of breath tends to worsen. 2. Some patients may also experience chest pain, dizziness, or fainting. 3. Some patients may cough up blood, usually only a small amount, but occasionally there can be a significant amount. 4. Patients with pulmonary hypertension caused by chronic obstructive pulmonary disease may experience repeated symptoms of coughing and coughing up phlegm. 5. Patients with pulmonary hypertension often experience fatigue and weakness.
Causes and Hazards of Bradycardia
The main causes of bradycardia include the following: 1. Physiological bradycardia, which occurs in normal individuals such as athletes and some elderly people, mainly due to increased vagal tone; 2. Cardiac diseases, such as sick sinus syndrome, severe atrioventricular block, myocarditis, and acute inferior myocardial infarction; 3. Other diseases, such as hypothyroidism and hyperkalemia. Physiological bradycardia generally poses no harm and does not require intervention. Pathological bradycardia, when the heart rate significantly slows down, can lead to a decrease in cardiac output, causing insufficient blood supply to the brain, resulting in symptoms such as dizziness, visual obscurity, and fainting. It can also cause coronary artery supply insufficiency leading to angina, as well as symptoms of fatigue and reduced exercise tolerance, requiring timely treatment.
Arrhythmia is what?
Arrhythmia refers to abnormalities in the frequency, rhythm, origin, or conduction of the heartbeats. It can occur in healthy individuals as well as those with related diseases, and may involve cardiac diseases or other medical conditions. The primary mechanism behind the occurrence of arrhythmias is the abnormal formation of cardiac impulses or the abnormal conduction of these impulses. It is important to actively seek the causes of arrhythmias and control the factors that trigger them. For diseases associated with arrhythmias, proactive management is necessary. When severe arrhythmias occur, timely and effective treatment is crucial to prevent adverse outcomes.
How to treat bradycardia
People with bradycardia should maintain good habits in daily life, eat a light diet, exercise reasonably, avoid overwork and staying up late, refrain from smoking and drinking, and keep a relaxed mood. Medications such as Xinbao Pills can be taken to increase the heart rate. Additionally, consuming traditional Chinese medicines like ginseng can also help in increasing the heart rate. For severe bradycardia that causes repeated symptoms like dizziness, visual obscurity, or fainting, and even episodes of Adams-Stokes syndrome, such as sick sinus syndrome or third-degree atrioventricular block, it is crucial to promptly visit a hospital. Active pacing treatment should be administered to increase the patient's heart rate, in order to prevent sudden cardiac arrest and avoid sudden cardiac death.
What are the dangers of bradycardia?
If the bradycardia is physiological, it generally does not harm the body and does not require special treatment. If the bradycardia is pathological, when the heartbeat significantly slows down, it can cause a decrease in cardiac output due to the slow heart rate, leading to symptoms of insufficient cardiac output, insufficient blood supply to the brain which can cause dizziness, visual disturbance, fainting, and other symptoms. Insufficient coronary artery supply can induce angina, and insufficient perfusion of the kidneys can lead to reduced urine output and kidney damage. Therefore, if a patient with bradycardia has a slow heart rate that leads to obvious symptoms, it is necessary to install a pacemaker for pacing treatment to increase the heart rate.
