Can people with coronary heart disease eat eggs?
Eggs contain rich proteins that are easily digested, absorbed, and utilized by the human body. Eggs also contain a variety of amino acids, including some essential amino acids that the body cannot synthesize on its own and must be ingested through diet. Eggs are beneficial for human growth and development, and patients with coronary heart disease can consume eggs, but they should be mindful of the quantity. Patients with coronary heart disease should adhere to a low-salt, low-fat diet, avoid fatty meats or animal organs, and generally consume fewer foods that are high in cholesterol and fat. Additionally, patients should adjust their lifestyle, follow medical advice, take medications on time, and undergo regular check-ups.
Atypical symptoms of myocardial infarction
We say myocardial infarction is a serious heart disease. Common symptoms of myocardial infarction include chest pain. However, some patients with myocardial infarction do not present with chest pain but exhibit other atypical symptoms. For example, some patients present with severe chest tightness and shortness of breath, or acute left heart failure. Others may seek treatment for palpitations or slow heart rate and other arrhythmias. Some exhibit symptoms like toothache or upper abdominal pain, while others may experience dizziness. There are also patients who present with low blood pressure or even go into shock. Therefore, for these patients, it is crucial to perform timely tests like electrocardiograms and troponin levels, and have a specialist make a diagnosis to avoid delays in treatment.
How to lower high blood pressure?
Hypertension is divided into primary hypertension and secondary hypertension. If it is secondary hypertension, removing the factors that cause high blood pressure can cure it. For example, if the hypertension is caused by an adrenal tumor, removing the tumor can normalize blood pressure. However, if diagnosed with primary hypertension, lifelong medication is required. There are many types of medications available, which need to be specifically analyzed based on the individual situation. If the patient primarily has high systolic pressure, it is recommended to use some calcium channel blockers, which are commonly used for elderly patients who primarily exhibit high systolic pressure. If it is primarily high diastolic pressure, some ACE inhibitors or ARBs are suggested. If sympathetic excitement is predominant, some β-blockers can be used. (Medication should be taken under the guidance of a professional doctor.)
Can heart failure be cured?
We say that some early-stage heart failure can be cured, such as peripartum cardiomyopathy and thyrotoxic cardiomyopathy. If discovered and treated early, there is hope for a cure. However, most heart failure cannot be cured. Although some psychological failures cannot be cured, if patients can receive early treatment and effective treatment, take their medication on time, and have regular check-ups as advised by their doctor, most heart failure can still be controlled or alleviated. However, if heart failure is detected and not actively treated, even mild heart failure may gradually worsen, or even become end-stage heart failure.
How many ventricular premature beats per day?
Ventricular premature beats can be caused by physiological reasons, diseases, ion disturbances, certain medications, and so on. If a healthy person without any diseases experiences ventricular premature beats, they should quit smoking, limit alcohol intake, ensure adequate rest, avoid staying up late, avoid excessive fatigue, and drink less or avoid strong tea, coffee, and other substances that stimulate the sympathetic nervous system. If ventricular premature beats are caused by other reasons, the specific cause should be determined by a specialist based on the medical condition and related examinations, and a reasonable treatment plan should be provided. (The use of medications should be conducted under the guidance of a doctor.)
"Tachycardia" means heart beats too fast.
We define a heart rate over 100 beats per minute as tachycardia, which can be sinus tachycardia, atrial tachycardia, junctional tachycardia, among others. Moreover, tachycardia can be physiological or pathological. For instance, a person experiencing tachycardia during intense physical activity or emotional excitement without any organic disease, and if this tachycardia is sinus tachycardia, then it is considered related to the intense activity or emotional state. On the other hand, conditions like anemia, hyperthyroidism, or heart failure can also lead to tachycardia. Whether tachycardia is physiological or pathological, and whether it is sinus or caused by other pacemakers in the heart, should be determined by a specialist.
The difference between ventricular premature beats and atrial premature beats.
Atrial premature beats are excitations of the heart initiated by the atrium and are prematurely triggered; ventricular premature beats refer to heart excitations initiated by the ventricles, which are also premature. On the electrocardiogram (ECG), atrial premature beats can be seen as prematurely occurring P waves and QRS complexes, where the shape of the QRS complex is consistent with that of the normal sinus rhythm. In contrast, ventricular premature beats on the ECG are shown as prematurely occurring wide and abnormal QRS complexes, with no preceding P wave.
Treatment of constrictive pericarditis
Constrictive pericarditis refers to a disease in which the heart is surrounded by a densely thickened fibrotic or calcified pericardium, restricting ventricular diastolic filling and producing a series of circulatory disorders, typically chronic in nature. In China, the most common cause of constrictive pericarditis is tuberculosis. Constrictive pericarditis is a progressive disease, and most patients will develop chronic constrictive pericarditis. At this stage, pericardiectomy is the only effective treatment method. It should be performed early to avoid complications such as cardiac cachexia, severe liver dysfunction, and myocardial atrophy, with surgery usually carried out after controlling the pericardial infection. For tuberculosis patients, anti-tuberculosis treatment should continue for one year after surgery.
Symptoms of acute pericarditis
Acute pericarditis is an acute inflammatory disease of the visceral and parietal layers of the pericardium, with the most common cause being viral infections. The hallmark of acute pericarditis is pain in the precardiac area behind the sternum. The nature of the pain is very sharp, typically occurring during the fibrinous exudation phase of inflammatory changes, caused by friction between the visceral and parietal layers of the pericardium. The pain can radiate to the neck, left shoulder, and even the upper abdomen. It is associated with respiratory movements and often worsens with coughing, deep breathing, or changing body positions. When fluid exudes into the pericardium, separating the visceral and parietal layers, the patient's pain may decrease or disappear. However, some patients may experience symptoms such as breathing difficulties and edema due to cardiac tamponade.
Pericarditis is caused by what?
Pericarditis refers to the inflammatory disease of the visceral and parietal layers of the pericardium. It can be classified according to its etiology into infectious, non-infectious, allergic, and immune pericarditis. Causes of infectious pericarditis include viral, purulent, tuberculous, and fungal pericarditis. Non-infectious pericarditis can be caused by acute myocardial infarction, uremia, tumors, trauma, aortic dissection, radiation, acute idiopathic, and sarcoidosis, among others. Causes of allergic or immune pericarditis include rheumatic, vasculitis, drugs, and more. Some patients remain undiagnosed after examinations and are categorized as having idiopathic pericarditis or nonspecific pericarditis.
