Is cor pulmonale contagious, is lung disease contagious? What other diseases are contagious?

Cor pulmonale is not contagious!

What is Cor pulmonale?

Cor pulmonale is caused by chronic bronchitis, obstructive emphysema, bronchiectasis, tuberculosis, bronchial asthma and pneumoconiosis, which in turn causes right ventricular hypertrophy and develops into right heart failure. Because the disease develops slowly, often taking years or decades to develop into cor pulmonale, it is more common in the elderly and is a systemic disease caused by cardiopulmonary dysfunction.

The main clinical symptoms of cor pulmonale are long-term cough, sputum pupture, and varying degrees of dyspnea, especially after activity or in the cold season. In the compensatory phase of cardiopulmonary function, the patient can have no symptoms when he is quiet, and once he is slightly active, he will have symptoms such as shortness of breath, shortness of breath, palpitations, pain in the precordial area, fatigue, and chest tightness.

What are the symptoms and complications of cor pulmonale.

The complications of cor pulmonale are mainly pulmonary encephalopathy, which is also the most dangerous complication, early headache, irritability, vision loss, trance, lethargy and even coma, and in severe cases, it can cause cerebral hemorrhage, cerebral herniation, and when the respiratory circulation center is compressed, the patient can die suddenly. This is followed by gastrointestinal bleeding, which can lead to shock due to a drop in blood pressure due to massive bleeding or disseminated intravascular coagulation. When complicated by acid-base balance imbalance and electrolyte imbalance, it can cause various arrhythmias and liver and kidney dysfunction, which is an important cause of death from cor pulmonale.

In the past, it was thought that "lung disease" was contagious, and this "lung disease" was tuberculosis. Patients suffering from pulmonary tuberculosis are called open tuberculosis when the sputum bacteria are positive, which is contagious, so patients who encounter coughing, sputum, and blood in the sputum should pay attention to disease prevention. Pulmonary tuberculosis is a disease transmitted through the respiratory tract, and lung cancer is different from pulmonary tuberculosis, which is a malignant tumor that causes abnormal proliferation of local cells and loses normal cell morphology and dynamics under the action of a variety of different carcinogenic factors.

Cancer cells discharged through sputum degenerate and die rapidly due to evaporation of sputum water, and even fresh sputum is needed to make cancer cells grow and multiply outside the body, and various nutrients and specific conditions are required. Scientists often need to go through a lot of hard work to succeed in cultivating a living cancer cell, so cancer is not contagious.

In animal experiments, animals with tumors were co-kept with animals without tumors, and after a long time, no direct infection was found. In some families, more than one person has developed lung cancer or other cancers, which may be related to the fact that the family members share genes and they may be in the same cancer-causing environment. Such as smoking, exposure to radioactive substances, etc., so malignant tumors can occur successively in the same family.

Hello. There are many pathogens of pneumonia, such as bacteria, viruses, and atypical pathogenic bacteria, among which viruses and atypical pathogenic bacteria have a certain degree of infectivity, if the patient is diagnosed with viral pneumonia or atypical pathogenic bacterial infection, it is necessary to avoid contact with the elderly or children as much as possible to induce mutual cross-infection, if the patient is diagnosed with pneumonia, we need to further improve the blood routine, C-reactive protein, procalcitonin, virus antibody, mycoplasma antibody, sputum culture and other related examination items

Evaluate the pathogen, according to different measures to take different **, for example, when the patient is a bacterial infection, we need to use antibiotics **, commonly used antibiotics, including cephalosporin, penicillin, azithromycin, etc., if the patient is a viral infection, we need to use antiviral drugs, such as: Qingkailing, Pudilan, etc., if the patient is an atypical pathogenic bacterial infection, we can use macrolide azithromycin, erythromycin or quinolone levofloxacin, moxifloxacin, etc.

Good luck.
