Is it called hypertension if the diastolic blood pressure is high?
High diastolic pressure, which is an increase in diastolic pressure, is also considered hypertension when the diastolic pressure exceeds 90mmHg. If you have hypertension, it is essential to have a formal medical examination at a hospital, such as blood tests for lipids and glucose to check for diabetes and hyperlipidemia. Blood tests are also done to evaluate liver and kidney functions, to see if there are any kidney diseases causing the increase in blood pressure. Additionally, under the guidance of a doctor, conduct ambulatory blood pressure monitoring to observe the overall situation of blood pressure increase within 24 hours. Based on the results of the blood tests and ambulatory blood pressure monitoring, determine whether antihypertensive medication is needed and which type of medication to use.
What causes mitral regurgitation in young people?
Mitral regurgitation is a phenomenon caused by incomplete closure of the mitral valve. From a medical perspective, when the left ventricle contracts, the mitral valve should be closed to prevent blood from flowing back into the left atrium, ensuring that the blood in the left ventricle can be fully pumped into the aorta to meet the needs of the body's tissues and organs. If there is incomplete closure of the mitral valve, the blood in the left ventricle will flow back into the left atrium, affecting the pumping efficiency of the left ventricle. If it is a mild closure insufficiency, generally it is not a big problem, but if it is moderate to severe, it often easily triggers the onset of heart failure.
Symptoms of myocardial infarction
Myocardial infarction is a relatively common disease in daily life, and it also poses a serious threat to people's health and safety. The symptoms of a myocardial infarction mainly include the following aspects: First, severe chest pain, which is often the most common symptom of myocardial infarction, typically feels like a crushing sensation or is accompanied by a feeling of impending doom. Second, symptoms of heart failure, which, when myocardial infarction is complicated by heart failure, often manifest as difficulty breathing and profuse sweating. Third, symptoms of arrhythmia, which, when myocardial infarction is complicated by arrhythmia, often presents with symptoms like palpitations and dizziness.
How does mitral valve insufficiency lead to heart failure?
Mitral valve regurgitation can easily lead to heart failure, especially left heart failure. This is because, when there is moderate or severe mitral regurgitation, the left ventricle contracts, and a large amount of blood in the left ventricle flows back into the left atrium. When the ventricle relaxes and fills again, the volume of blood in the left ventricle significantly increases, leading to an overload in the capacity of the left ventricle. Over time, this causes left ventricular hypertrophy, a decline in the heart's pumping function, and thus, heart failure occurs. In terms of symptoms, it presents as exertional dyspnea and paroxysmal nocturnal dyspnea, among other symptoms. When these symptoms occur, it is necessary to go to the hospital for proper examination and treatment, and to take diuretic medications under the guidance of a doctor to improve the symptoms.
Are ventricular premature beats serious?
Ventricular premature beats are a very common condition in daily life, so many patients often ask their doctors this question: Are my ventricular premature beats severe? This needs to be analyzed based on the specific issue and circumstances. First, if there is no structural heart disease, these premature beats are generally known as functional ventricular premature beats, which are usually not serious and do not endanger life safety. Second, if there is concomitant structural heart disease, such as coronary heart disease or cardiomyopathy, then these ventricular premature beats are generally considered risky, and it is necessary to take medication or undergo surgery under the guidance of a doctor.
What tea can you drink to lower blood lipids if you have hyperlipidemia?
Hyperlipidemia is a very common disease in our daily life, and our country is a major tea culture nation with a wide variety of teas, such as black tea, green tea, and so on. Among these, certain teas are beneficial for reducing blood lipids if consumed regularly. Generally, teas like Gynostemma tea, buckwheat tea, or Pu-erh tea have been shown by modern medical research to have a cholesterol-lowering effect. Therefore, it is beneficial to regularly consume teas such as buckwheat tea, Pu-erh tea, or Gynostemma tea in our daily lives to help reduce blood lipids.
The causes of embolism in mitral stenosis
Mitral stenosis in patients can lead to embolism due to the tendency of mitral stenosis to cause enlargement of the left atrium. The enlargement of the left atrium is a key anatomical factor leading to atrial fibrillation and cardiac arrhythmias. When atrial fibrillation occurs, it is easy for blood clots to form in the left atrium, especially in the area of the left atrial appendage. When a blood clot breaks off, it can travel with the bloodstream and cause occlusion of the corresponding blood vessels, resulting in embolic complications. Timely surgical intervention to treat mitral stenosis can effectively prevent complications such as atrial enlargement and blood clots caused by mitral stenosis.
Can people with atrial fibrillation drink alcohol?
Atrial fibrillation is a common arrhythmia among many middle-aged and elderly people, and in our country, which has a strong culture of alcohol consumption, many people enjoy drinking. So, can you drink alcohol if you have atrial fibrillation? My advice is that it's best not to drink. Modern medical research has shown that alcohol can potentially trigger attacks of atrial fibrillation, and in our clinical practice, we often find that many patients experience an onset of atrial fibrillation by drinking alcohol, sometimes even necessitating hospital treatment due to the episodes. Therefore, it is recommended that patients with atrial fibrillation avoid or minimize alcohol consumption.
Is mild mitral valve regurgitation serious?
Mild mitral valve regurgitation, as the name implies, is mild and not severe. From a medical perspective, most cases of mild mitral valve regurgitation are normal physiological phenomena in the human body, which do not cause symptoms, do not affect health, and do not require treatment. Therefore, there is no need to overly worry about this condition in daily life. Of course, maintaining good lifestyle habits is necessary, such as exercising regularly with activities like running and practicing yoga, not smoking, not drinking alcohol, ensuring good sleep, and keeping a pleasant mood. Regarding diet, eat less spicy and greasy food and consume more vegetables and fruits. Good lifestyle habits can effectively prevent the worsening of mitral valve regurgitation.
Can someone with an atrial septal defect go swimming?
Atrial septal defect is not uncommon in our daily lives. Many patients with atrial septal defects often ask their doctor if they can swim. This has to be analyzed based on specific circumstances. If the atrial septal defect is not severe, and it's just a minor atrial septal defect, generally it does not affect the patient's daily activities, such as swimming or running. However, if the atrial septal defect is severe, especially if it has led to heart failure and heart enlargement, in this situation, one should definitely not engage in strenuous activities such as swimming or running.
