Early symptoms of coronary heart disease
The early symptoms of coronary heart disease primarily appear as exertional angina, manifesting as chest pain during physical activity or emotional agitation. The pain is located behind the sternum and may radiate to the precordial area, feeling oppressive or accompanied by a tightening sensation. The chest pain generally lasts from several minutes to more than ten minutes, most often between three to five minutes, and can be quickly relieved by rest. Of course, some individuals do not exhibit clear symptoms of chest pain, but rather symptoms like chest tightness and palpitations. Once patients with coronary heart disease experience exertional angina, it is vital to promptly visit a hospital for comprehensive examinations such as electrocardiograms, exercise tests, cardiac echocardiography, and if necessary, coronary angiography to confirm the diagnosis and commence treatment as soon as possible.
Is mild regurgitation of the mitral and tricuspid valves severe?
Mitral and tricuspid valve regurgitation with a small amount of reflux is generally not serious if it is not associated with any related organic diseases, nor will it lead to adverse consequences, and therefore does not require any corresponding treatment. If the minor reflux of the mitral and tricuspid valves is caused by an organic disease leading to an enlarged heart, the condition is then considered more severe. It is necessary to actively identify the specific related diseases and provide appropriate treatment for different diseases to effectively control the condition long-term. This is crucial to prevent further exacerbation of the disease, which could lead to further enlargement of the heart and increased severity of mitral and tricuspid valve regurgitation. When significant regurgitation occurs, it can cause a marked increase in the preload of the ventricles, promoting the occurrence of heart failure and thereby leading to severe adverse consequences.
Will patent ductus arteriosus cause mitral regurgitation?
Patent ductus arteriosus usually does not cause mitral regurgitation. Since the pressure in the aorta is greater than that in the pulmonary artery, blood from the aorta will shunt to the pulmonary artery, significantly increasing blood flow in the pulmonary circulation. This eventually leads to pulmonary hypertension, causing an increased afterload on the right ventricle. Over time, an increased afterload on the right ventricle can lead to right ventricular enlargement and right heart failure, resulting in dilation of the tricuspid annulus and tricuspid regurgitation due to incomplete closure. Patients with patent ductus arteriosus need to seek prompt medical assessment to determine the need for surgical treatment. For patients with surgical indications, surgery should be administered promptly to avoid the adverse consequences of long-term blood shunting.
Does atrial septal defect increase in size as age progresses?
The defects in the atrial septum tend to enlarge as one ages, and with the enlargement of the atrial septal defect, the patient's condition will also gradually worsen. Of course, some small atrial septal defects may close gradually as one ages after birth. For atrial septal defects that cannot close, if they gradually enlarge, they will lead to symptoms like chest tightness and shortness of breath in patients and are likely to cause respiratory infections. As the condition progresses, it can lead to pulmonary hypertension and cause right heart failure. For atrial septal defects that cannot close, if there are indications for surgery, active surgical treatment should be provided to prevent the worsening of the condition.
What are the symptoms of mild mitral regurgitation?
"Mild mitral regurgitation generally does not cause significant symptoms, and mild mitral regurgitation is often seen under physiological conditions. As age increases, due to aging and other reasons, mild regurgitation may occur in the mitral valve, which does not result in adverse consequences. However, sometimes mild mitral regurgitation may be caused by heart disease leading to heart enlargement and annular dilation. In such cases, it is crucial to actively treat the underlying heart disease to prevent further enlargement of the heart, which could worsen the mitral regurgitation. Therefore, when mild mitral regurgitation occurs, it is important to actively investigate the cause of the regurgitation."
What causes atrial fibrillation?
Atrial fibrillation most commonly occurs in patients with organic heart disease, such as rheumatic heart disease, coronary atherosclerotic heart disease, hypertensive heart disease, cardiomyopathy, constrictive pericarditis, and chronic pulmonary heart disease, etc. It can also be seen in diseases of other systems such as hyperthyroidism, etc. In addition, as age increases, the incidence of atrial fibrillation also increases. Some causes of atrial fibrillation are unknown and may be triggered by emotional stress, physical activity, or heavy drinking. For atrial fibrillation, once an episode occurs, it is important to actively administer appropriate medications to control it, to avoid the adverse consequences of persistent atrial fibrillation.
Does cordyceps have an effect on cardiomyopathy?
Eating cordyceps has no scientifically proven therapeutic effect on cardiomyopathy. However, people with cardiomyopathy can appropriately consume some cordyceps without adverse effects on their condition. Moreover, cordyceps can regulate the body's immune ability and has certain anti-fatigue effects, which can still have beneficial impacts on the patient's health. Patients with cardiomyopathy should undergo long-term treatment based on their underlying heart disease. Different types of cardiomyopathy require different treatment measures. For example, patients with dilated cardiomyopathy need to be treated long-term with drugs that inhibit myocardial remodeling to improve prognosis. If heart failure occurs, treatment for heart failure should be given to improve the symptoms of heart failure.
Is a blood pressure of 150 severe?
A blood pressure of 150 mmHg is not necessarily serious by itself; further risk stratification of blood pressure needs to be conducted. If the risk stratification of blood pressure is high or very high, the condition is relatively serious and active antihypertensive treatment is necessary to effectively reduce the future risk of cardiovascular and cerebrovascular events, thus improving the patient's prognosis. If the blood pressure of 150 mmHg is classified as low or medium risk, this level of blood pressure is not serious, but it still requires long-term standardized treatment to control the blood pressure to the target level. If blood pressure is not well controlled, long-term hypertension can gradually make the condition very serious, increase the risk stratification, and significantly raise the likelihood of cardiovascular and cerebrovascular events.
Does patent ductus arteriosus affect appetite?
When patent ductus arteriosus (PDA) progresses to a certain extent, it can affect appetite. If the patent ductus arteriosus causes pulmonary arterial hypertension, leading to right heart failure, it results in congestion of the gastrointestinal tract and the liver. This significantly impacts the digestive and absorption functions of the gastrointestinal tract, causing reduced appetite in the patient. Some patients may also experience nausea, vomiting, and abdominal distension. For patients with patent ductus arteriosus, if there are indications for surgery, timely surgical treatment should be carried out to correct the anatomical abnormalities and prevent the progressive worsening of the patent ductus arteriosus, which could lead to adverse outcomes.
Are frequent ventricular premature beats serious?
Frequent ventricular premature beats can be serious depending on the specific circumstances; some cases are more severe, while others are not. If the frequent ventricular premature beats occur on the basis of severe heart diseases such as severe heart failure, acute myocardial infarction, or are caused by severe hypokalemia, these cases of frequent ventricular premature beats are relatively severe. They carry the risk of progressing to malignant arrhythmias leading to sudden cardiac death, thus requiring prompt and active management to prevent adverse outcomes. In healthy individuals, frequent ventricular premature beats triggered by factors such as staying up late or fatigue are generally not serious. They can quickly recover with adequate rest and sufficient sleep.
