Cor pulmonale, also known as pulmonary heart disease, refers to the increased pulmonary vascular resistance caused by pathological changes in the bronchi, lung tissue, thorax, or pulmonary vessels, leading to pulmonary arterial hypertension and subsequent structural and functional changes in the right ventricle. This condition is clinically referred to as cor pulmonale. The causes of cor pulmonale can be divided into three main categories: The first category is diseases of the bronchi and lungs, such as chronic obstructive pulmonary disease (COPD), which accounts for approximately 80%-90% of cases. Other causes include bronchial asthma, bronchiectasis, severe pulmonary tuberculosis, interstitial pneumonia, and more. The second category involves diseases related to disorders of thoracic cage movement, such as various thoracic deformities, kyphoscoliosis, spinal tuberculosis, arthritis leading to extensive pleural adhesions, and deformities caused by thoracic plastic surgery. The third category includes pulmonary vascular diseases, such as pulmonary arterial hypertension, pulmonary thromboembolism, and other conditions leading to narrowing or blockage of pulmonary arteries, all of which can progress to cor pulmonale.

Symptoms of cor pulmonale

Cor pulmonale refers to a disease characterized by increased pulmonary vascular resistance due to pathologies of the bronchi, lung tissue, chest wall, and blood vessels of the lungs, leading to pulmonary arterial hypertension and structural and functional changes in the right ventricle. The common clinical symptoms of cor pulmonale include coughing, expectoration, shortness of breath, significant palpitations, and breathing difficulties after physical activity, reduced work capacity, and exacerbation of the above symptoms during acute infection phases. Some patients may experience chest pain and hemoptysis. The second set of symptoms relates to heart and lung function, manifesting during the decompensation phase. For instance, some patients may develop respiratory failure, and experience headaches, decreased appetite, drowsiness, significant edema in the lower extremities, and further symptoms such as arrhythmias, anorexia, abdominal distension, and nausea.

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.

Is premature beat a type of heart disease?

Premature heartbeats belong to heart disease, and any disease that affects heart function and conduction is called heart disease. However, heart disease can be divided into organic heart disease and functional heart disease. Premature beats can also be due to different causes, categorized as physiological and pathological premature beats. Physiological premature beats are common in the normal population and are caused by disturbances in the nerves regulating the heart due to various reasons. Pathological premature beats are caused by organic heart disease, and it is necessary to treat the primary disease while correcting these premature beats.

Is heart palpitations a heart disease?

Palpitations are one of the main symptoms of cardiovascular disease, but they should not be equated with it. Some palpitations do not accompany arrhythmias and can also occur in normal people, especially when lying on the left side, which might be noticeable. It is commonly seen in normal individuals who are nervous and sensitive, as well as in some anxious people. Normal people might experience palpitations during intense exercise; these could be due to sinus tachycardia or a high-output circulatory state, but most other cases should be evaluated to exclude heart disease.

Can people with heart disease drink alcohol?

Patients with heart disease should not drink alcohol, especially those with severe heart conditions, including heart failure and arrhythmias. Drinking alcohol can excite the sympathetic nervous system, increase heart rate, enhance myocardial oxygen consumption, increase cardiac burden, and worsen arrhythmias and heart failure. Additionally, patients with organic heart disease who regularly require medication should avoid alcohol. Alcohol can chemically interact with certain medications or reduce their effectiveness, potentially harming the body.
