Complications of cor pulmonale commonly include several conditions. The first is pulmonary encephalopathy, caused by respiratory failure leading to hypoxia and carbon dioxide retention, which can cause somnolence in patients and, in severe cases, lead to coma. The second is acid-base imbalance and electrolyte disturbances. Cor pulmonale may present with various electrolyte disturbances, such as hyponatremia and hypokalemia. The third is arrhythmias, most commonly manifesting as atrial premature beats or paroxysmal supraventricular tachycardia. The fourth complication is shock. Shock is not very common in cor pulmonale, but if it occurs, the prognosis is poor.

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.

What is heart disease?

Heart disease is caused by various factors that invade the heart, resulting in the loss of its normal physiological functions. Common causes of heart disease include rheumatic heart disease, congenital heart disease, viral myocarditis, coronary artery disease, and pulmonary heart disease. These diseases are considered organic heart diseases, caused by various reasons that lead to pathological changes in the heart's muscles, valves, etc., losing the heart's normal ability to pump blood and supply the body with blood.

What does heart disease feel like?

Heart disease is a very common category of diseases in our daily lives, with a wide range of heart conditions. What are the general symptoms or feelings associated with heart disease? They often manifest in the following ways: First, palpitations or arrhythmias. Patients with arrhythmias often experience symptoms of palpitations, which are quite common. Second, chest tightness and chest pain, such as in coronary heart disease or hypertrophic cardiomyopathy. This type of heart disease often presents with symptoms of chest tightness and chest pain. Third, symptoms of heart failure, such as exertional dyspnea or nocturnal paroxysmal dyspnea. These symptoms are often indicative of heart failure. These three major categories are the most common symptoms of heart disease. If you experience any of these symptoms, be sure to visit the cardiology department of a hospital for a formal examination.

How long does heart disease generally hurt?

1. Chest pain caused by angina due to coronary heart disease is located in the middle to lower third of the sternum, with unclear boundaries. It is often triggered by physical activities or emotional excitement and may radiate to the throat, lower jaw, left shoulder, and inner side of the left arm. The pain lasts for a few minutes to more than ten minutes, typically between three to five minutes, and rarely exceeds half an hour. It can be relieved by rest or by taking nitroglycerin under the tongue. The nature of the pain is feelings of stuffiness, pressure, or constriction, and may also feel like a burning sensation, but is not sharp like needle pricks or cuts. 2. The location and nature of the chest pain in acute myocardial infarction are the same as with angina, but it lasts longer, is more severe, and its triggers are less evident. It can occur even while at rest, accompanied by symptoms such as sweating, nausea, vomiting, heart palpitations, and difficulty breathing. Unlike with angina, regular rest or taking nitroglycerin under the tongue does not completely alleviate the pain.

Can people with heart disease drink alcohol?

Patients with heart disease should not consume alcohol, especially those with severe heart conditions such as coronary heart disease, severe arrhythmias, and viral myocarditis. These patients especially should avoid alcohol as they need to use many medications during treatment. If they consume alcohol, the alcohol entering the body can chemically interact with some medications, leading to reduced efficacy, diminished effects, or causing side effects. Additionally, for these heart disease patients, consuming alcohol can increase the burden on the heart and exacerbate symptoms of heart disease.
