Cardiomyopathy
Dilated cardiomyopathy clinical manifestations
Dilated cardiomyopathy is a type of heart disease characterized clinically by a significant enlargement of the heart, a marked reduction in ejection fraction, and a significant decline in heart function. Common clinical manifestations of this disease often present as heart failure symptoms, including chest tightness and shortness of breath after activity, nocturnal paroxysmal breathing difficulties, inability to lie flat, as well as swelling of the lower limbs and abdominal wall, and even conditions such as pleural effusion and ascites. Additionally, it may be associated with various types of arrhythmias, such as premature beats and tachycardia, especially ventricular tachycardia, which are all manifestations of dilated cardiomyopathy.
What should patients with cardiomyopathy pay attention to?
Patients with cardiomyopathy need to rest adequately, avoid overexerting themselves, and not get overly emotional to keep their mood calm and prevent an increased burden on the heart, which could trigger heart failure. In their diet, they should consume easily digestible foods that are high in superior protein and eat plenty of fruits and vegetables. These foods can provide the high-quality proteins, vitamins, and trace elements needed by the body, enhancing immunity and disease resistance. In the event of thrombosis and myocardial cell repair, systematic medication treatment under a doctor's guidance is essential to promote myocardial repair.
Can people with cardiomyopathy run?
Whether a person with myocardial disease can run or not depends on the extent of myocardial damage and clinical symptoms. If the myocardial damage is severe and there are significant clinical symptoms of heart failure and arrhythmia, this group should not run and needs bed rest. If strenuous activity would worsen heart failure, the myocardial damage is mild, with no typical clinical symptoms, and does not affect daily activities, this group can engage in appropriate exercises like walking or running, but the duration should not be too long, about 20 to 30 minutes each time.
Is cardiomyopathy life-threatening?
Whether cardiomyopathy poses a threat to life depends on the severity of the condition. Mild myocardial damage, if detected early, diagnosed early, and treated with effective medications in a timely manner, generally has a good prognosis, poses no threat to life, and leaves no sequelae. Severe myocardial damage, due to lack of timely treatment, can lead to serious complications such as heart failure, arrhythmias, and cardiogenic shock, which can endanger life safety. Therefore, early diagnosis, early treatment, and prevention of complications are crucial treatment measures for cardiomyopathy.
Does cardiomyopathy require surgery?
Firstly, whether myocardial disease requires surgery, we need to clarify the type of myocardial disease and the stage of myocardial disease, that is, the stage of heart function that has been affected. There are many types of myocardial diseases, including dilated cardiomyopathy, ischemic cardiomyopathy, and restrictive cardiomyopathy, for instance. The treatment plans for different types of myocardial diseases are not exactly the same. For example, dilated cardiomyopathy is generally treated with medication, and only in the very late stages of dilated cardiomyopathy, or what is known as stage IV heart function, when conventional medication is ineffective, heart transplantation might be considered if a donor is available and conditions allow. However, currently, heart donors are extremely rare, making this option quite difficult to achieve. The latest advances in clinical research have introduced artificial mechanical hearts available for transplantation, but the costs of surgery are very high, and the technology is not very mature yet. Therefore, the chances and opportunities for surgery are not very great and must be decided based on the situation. For other conditions, such as ischemic cardiomyopathy, if it is clearly caused by severe ischemia, we might consider addressing the factors causing myocardial ischemia, such as performing a coronary angiography. If there is severe coronary artery stenosis, we might consider implementing a coronary artery stent or coronary artery bypass grafting to alleviate the ischemic factors. In cases like restrictive cardiomyopathy, if there are severe restrictive factors contributing to the disease, surgical treatment might also be pursued.
Can dilated cardiomyopathy be inherited?
We say that dilated cardiomyopathy is a type of cardiomyopathy characterized by enlargement of the left ventricle or both ventricles, accompanied by systolic dysfunction. Some cases of dilated cardiomyopathy are familial, with the main inheritance patterns being autosomal dominant, X-linked recessive, and more rarely, mitochondrial inheritance. The cause of most dilated cardiomyopathies is unclear, but potential causes include infections, non-infectious inflammation, endocrine metabolic disorders, genetics, psychological trauma, and poisoning, including alcohol poisoning. Alcoholism is a common cause of dilated cardiomyopathy in China. Clinically, dilated cardiomyopathy presents with cardiac enlargement, heart failure, arrhythmias, thromboembolism, and sudden death.
Treatment of Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, due to unknown causes and often related to genetic factors, is difficult to prevent. It is important to guide patients on how to lead their lives, reminding them to avoid intense physical activities, heavy lifting, or breath-holding to reduce the incidence of sudden death. Avoid using drugs that enhance myocardial contractility and reduce cardiac capacity load, such as digoxin and nitrates, to decrease the aggravation of left ventricular outflow tract obstruction. The treatment principle for this disease is to slow down the hypertrophy of the myocardium, prevent tachycardia, and maintain normal sinus rhythm. It also aims to relieve the narrowing of the left ventricular outflow tract and counteract arrhythmias. Currently, the use of beta blockers and calcium channel blockers is advocated. For severe obstructive patients, interventional and surgical treatments can be carried out, including the implantation of a dual-chamber DTD pacemaker, and the ablation or removal of hypertrophied interventricular septum myocardium.
What department should I register for cardiomyopathy?
Myocardial disease is a common and frequently occurring disease in clinical practice, caused by various reasons leading to pathological changes in the myocardium. Common causes include viral infections, immune system disorders, and other factors, which can lead to degeneration, necrosis, fibrosis, and interstitial edema of the myocardium. This can cause heart failure, arrhythmias, and in severe cases, even death. Therefore, early diagnosis and timely treatment can save patients' lives and alleviate their suffering. It is necessary to consult with a psychiatrist, undergo relevant examinations under the guidance of a psychiatrist, make a clear diagnosis, and actively treat and rescue the patients.
Can myocarditis cause dizziness?
Cardiomyopathy is a fairly common disease in our daily lives. From a medical perspective, cardiomyopathy can usually be divided into dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, and restrictive cardiomyopathy. When cardiomyopathy is present for a long time, it may cause a decline in the heart’s pumping function, leading to a reduction in cardiac output and resulting in heart failure. In such cases, due to insufficient blood supply to the brain, patients often experience symptoms of dizziness. If diagnosed with cardiomyopathy, under the guidance of a doctor, regulated medication can often significantly improve symptoms, including dizziness. (Specific medication usage should be conducted under the guidance of a doctor; do not self-medicate.)
Clinical manifestations of dilated cardiomyopathy
The clinical manifestations of dilated cardiomyopathy can be summarized in two words: "three hearts," which are reflected in the following three aspects. First, heart enlargement, such as through chest X-rays or echocardiography, often reveals a notable enlargement of the patient's heart. Second, arrhythmias; dilated cardiomyopathy often accompanies a variety of arrhythmias, such as frequent ventricular premature beats, tachycardia, or atrial fibrillation. Third, heart failure. Dilated cardiomyopathy often results in symptoms of heart failure, such as exertional dyspnea and paroxysmal nocturnal dyspnea.
