Symptoms of chronic heart failure
Chronic heart failure can be divided into left heart failure, right heart failure, and total heart failure. The symptoms of left heart failure primarily manifest as congestion in the pulmonary circulation, that is, a reduction in cardiac output. Patients may experience varying degrees of breathing difficulties, starting with exertional dyspnea, then orthopnea, followed by paroxysmal nocturnal dyspnea, and eventually acute pulmonary edema. Additional symptoms may include coughing, expectoration, hemoptysis, fatigue, tiredness, dizziness, reduced exercise tolerance, and symptoms of insufficient blood supply to organs and tissues, including oliguria and kidney damage. The symptoms of right heart failure can present as gastrointestinal symptoms, such as abdominal distension, loss of appetite, nausea, vomiting, and also exertional dyspnea. When both left and right heart failures occur, it is referred to as total heart failure. In cases of total heart failure, symptoms of both left and right heart failures may be present.
Causes of Heart Failure
Heart failure can be divided into acute heart failure and chronic heart failure. There are many causes of acute heart failure, such as acute coronary syndrome, hypertensive emergency, acute massive pulmonary embolism, right ventricular infarction, severe pulmonary hypertension, and so on. Chronic heart failure can also have many causes, for example, coronary artery disease and hypertension have become the main causes of chronic heart failure, rheumatic heart disease, and valvular heart disease can also cause chronic heart failure. Chronic cor pulmonale and high-altitude heart disease also have a certain incidence rate in China, among others.
Early symptoms of acute pericarditis
The early symptoms of acute pericarditis are pain, which is located behind the sternum or in the precordial area, typically seen in the fibrin exudative type of inflammation. This pain arises from the friction between the visceral pericardium and the parietal pericardium. The nature of the pain is very sharp and related to respiratory movement, commonly exacerbated by coughing, deep breathing, or swallowing. The pain can radiate to the neck, left shoulder, and left arm. As fluid accumulates in the pericardium and the two layers of the pericardium separate, the pain may decrease or disappear.
Late-stage symptoms of heart failure
The most common symptom of late-stage heart failure is dyspnea, which is often persistent. Even in a resting state, there can be shortness of breath. Mild activities, such as eating and urination, can exacerbate the breathing difficulties. Patients in the late stages of heart failure often experience persistent edema, and conventional diuretics are not effective. Patients may also exhibit restlessness, nausea, vomiting, loss of appetite, reduced urine output, and other symptoms. Additionally, low blood pressure can be observed on cardiac monitoring, among other findings.
What foods are good for tachycardia?
When experiencing tachycardia, it is first important to determine the cause. If the tachycardia is due to emotional excitement or excessive exercise, one should maintain stable emotions and rest adequately. If tachycardia is caused by other reasons such as atrial fibrillation with rapid ventricular rate, or paroxysmal supraventricular tachycardia, treatment should target the atrial fibrillation or the paroxysmal supraventricular tachycardia. Tachycardia caused by conditions like hyperthyroidism, fever, or anemia should be managed by treating the hyperthyroidism, anemia, fever, and lowering the body temperature, etc. During tachycardia, it is advised to avoid spicy foods, strong tea and coffee, alcohol, etc. The specific cause of tachycardia should be determined by a specialist who can then provide an appropriate treatment plan.
Constrictive pericarditis clinical manifestations
Patients with constrictive pericarditis often have a history of pericarditis, pericardial effusion, malignant tumors, and other diseases. Some patients have an insidious onset with no obvious clinical symptoms in the early stages. The main symptoms can include palpitations, exertional dyspnea, decreased exercise tolerance, fatigue, enlarged liver, pleural effusion, abdominal effusion, and edema of the lower limbs. Patients with constrictive pericarditis commonly present with elevated jugular venous pressure, and often have a reduced pulse pressure. Most patients exhibit a negative apical beat during systole, with a commonly faster heart rate. The rhythm can be sinus, atrial, or ventricular, with premature contractions possible, as well as Kussmaul's sign. In the late stages, muscle atrophy, cachexia, and severe edema can occur.
Can people with chronic heart failure smoke?
Patients with chronic heart failure should not smoke, as smoking can enhance the excitability of the sympathetic nervous system. Increased excitability of the sympathetic nervous system releases norepinephrine, elevating norepinephrine levels. This can cause peripheral vasoconstriction, increase the afterload on the heart, and accelerate heart rate. Both of these effects can increase myocardial oxygen consumption. Furthermore, norepinephrine has a direct toxic effect on myocardial cells, promoting myocardial cell apoptosis and participating in the pathological process of ventricular remodeling. Moreover, excitement of the sympathetic nervous system can also enhance myocardial stress, potentially promoting the occurrence of arrhythmias. Therefore, patients with chronic heart failure should not smoke.
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.
Can acute pericarditis be cured?
Patients with acute pericarditis should identify the cause of pericarditis and treat accordingly, rest in bed until chest pain and fever subside, administer analgesics for pain relief, and if pericardial effusion occurs, administer corticosteroids for patients who do not respond well to other medications for absorbing effusion. In cases of excessive pericardial effusion leading to acute cardiac tamponade, immediate pericardiocentesis and fluid drainage are necessary. For persistent recurrent pericarditis lasting over two years, and in patients who cannot be controlled with steroids, or those with severe chest pain, surgical pericardiectomy may be considered as a treatment option.
Causes of arrhythmia
There are many causes of arrhythmia, which can be physiological or pathological. Pathological causes can originate from the heart itself or from other diseases. For instance, normal individuals might experience sinus arrhythmia, and circumstances such as staying up late, emotional excitement, or excessive fatigue can lead to premature beats or sinus tachycardia, among others. Other diseases, such as hyperthyroidism or fever, can cause an increased heart rate. For example, pulmonary embolism can lead to atrial fibrillation. Heart-related diseases, like heart failure, can cause ventricular premature beats, and diseases of the sinoatrial node itself can lead to sick sinus syndrome, among others.
