Heart disease includes many types, such as chronic heart failure, acute myocardial infarction, rheumatic heart disease, arrhythmias, and more. If it is chronic heart failure with NYHA class II, it means the patient's physical activity is slightly limited, there are no symptoms at rest, but symptoms of heart failure may appear under normal activities. How serious NYHA class II chronic heart failure is needs to be analyzed based on the specific issue because this classification is quite subjective. Other factors, such as the patient’s echocardiographic ejection fraction, the end-diastolic diameter of the left ventricle, the underlying disease of the patient, the value of B-type natriuretic peptides, etc., need to be considered in a comprehensive analysis to judge the severity of the patient's condition.

Premonitory signs of a sudden heart attack

Sudden heart disease primarily refers to the sudden onset of acute myocardial infarction. Between 50% to 81.2% of patients have prodromal symptoms, experiencing significant chest discomfort, fatigue, palpitations during activity, shortness of breath, irritability, and angina in the days before the onset, with the most prominent being new or worsening angina. The angina is more frequent than before, more severe, lasts longer, and nitroglycerin relief is not significantly apparent; the triggers are also unclear. Sometimes, gastrointestinal symptoms such as nausea, vomiting, and upper abdominal bloating occur and are often misdiagnosed, causing delays in treatment.

How do you get heart disease?

There are many causes of heart disease, the most common being coronary atherosclerotic heart disease, which is due to long-term hyperlipidemia leading to arteriosclerosis. After the coronary arteries harden, the lumen narrows, resulting in insufficient myocardial blood supply and the onset of coronary heart disease. Rheumatic heart disease occurs when the body is infected with streptococcus and does not receive adequate treatment, leading to an abnormal immune response that attacks the heart valves, causing valve damage. Pulmonary heart disease is caused by long-term insufficient ventilation leading to emphysema, and pulmonary hypertension increases the resistance on the heart, causing right ventricular hypertrophy.

Which place is the best for a heart disease massage?

Premature cardiac contractions can occur in normal individuals. For younger people, fewer than 3 contractions per minute generally poses no issue, whereas for older individuals, fewer than 5 per minute is considered normal. However, it is recommended to conduct a 24-hour Holter monitor test. If this test shows more than 10,000 occurrences in 24 hours, it is advisable to consult a specialist to determine if medication or hospital treatment, such as radiofrequency ablation, is needed. Additionally, it is crucial to investigate the causes of premature cardiac contractions. If serious diseases are ruled out, it may be helpful to massage corresponding acupoints. Generally, massaging acupoints like the Neiguan and Hegu, which are associated with the kidney and heart meridians, is suggested. Massage of the Fuxi acupoint is also recommended; located at the front of the thigh, it is easier to massage when seated with the knee bent at a 90-degree angle.

Rheumatic heart disease etiology

Rheumatic heart disease is a type of organic heart disease, often caused by an abnormal immune response following a streptococcal infection, which affects the heart valves, resulting in valvular lesions, leading to stenosis or insufficiency, and posing significant risks to human health, severely impacting physical well-being. To prevent the occurrence of rheumatic heart disease, it is essential to actively control streptococcal infections, commonly including tonsillitis and upper respiratory tract infections. When a streptococcal infection occurs, effective antibiotics should be actively used to control the infection and reduce the incidence of rheumatic heart disease.

Is pulmonary heart disease serious?

Cor pulmonale refers to the disease characterized by changes in the structure and function of the right ventricle due to increased pressure resistance in the pulmonary vessels, caused by abnormalities in the bronchopulmonary tissue, thoracic cage, pulmonary vessels, etc., ultimately leading to pulmonary arterial hypertension. Common symptoms of cor pulmonale observed clinically include coughing, production of phlegm, shortness of breath, chest tightness after activity, and difficulty breathing. Some individuals may experience respiratory failure and symptoms of heart failure. The severity of cor pulmonale depends firstly on the underlying causes of the disease. For instance, conditions like pulmonary embolism and pulmonary hypertension generally have a poorer and more serious prognosis. Secondly, extensive lung infections leading to a loss of cardiopulmonary compensation, resulting in respiratory failure and heart failure, typically indicate a more severe condition.
