What are the symptoms of cor pulmonale?

Cor pulmonale refers to pulmonary heart disease, which is a heart disease caused by pulmonary hypertension due to lung disease. There will be symptoms of long-term cough, sputum, and difficulty breathing. It can be divided into acute cor pulmonale and chronic cor pulmonale. When faced with this disease, timely treatment and infection control should be provided. The following is a detailed introduction

Symptoms of cor pulmonale:

1. Compensatory stage of lung and heart function (including remission stage)

This stage is mainly characterized by the manifestation of chronic obstructive pulmonary disease (COPD). Chronic cough, sputum, shortness of breath, palpitations after activity, dyspnea, fatigue and decreased work endurance. Physical examination may show obvious signs of emphysema, weakened breath sounds on auscultation, occasional dry and wet rales, and mild edema in the lower limbs, which is obvious in the afternoon and disappears the next morning. The border of cardiac dullness is often difficult to percuss due to emphysema.

Heart sounds are distant, but there may be a hyperactive second heart sound in the pulmonary valve area, suggesting pulmonary hypertension. The presence of a systolic murmur in the tricuspid valve area or cardiac pulsation under the xiphoid process often indicates right heart hypertrophy and enlargement. In some cases, emphysema increases the intrapleural pressure, obstructing the vena cava return, and the jugular vein may be seen to be full. As the diaphragm descends, the upper and lower edges of the liver move downward significantly.

2. Decompensated lung and heart function (including acute exacerbation)

The main clinical manifestations of this stage are respiratory failure, with or without heart failure.
