Infective Endocarditis Guide

Infective pericarditis is caused by inflammation of the heart valves that have been invaded by microorganisms. This disease is completely unexpected and is divided into two different symptoms: acute disease and common disease, but both symptoms overlap. The advantage of the second symptom over the first is that the body will experience some unusual symptoms unexpectedly. Many patients can hear the abnormal sound waves of their own hearts through medical instruments, which means that the valve is damaged.

Infectious

1. Difficulty breathing:

Dyspnea refers to the patient's subjective feeling of lack of air or labored breathing, which is objectively manifested as changes in respiratory rate, depth and rhythm. According to the pathogenesis, dyspnea can be divided into six basic types: cardiac dyspnea, pulmonary dyspnea, central dyspnea, psychoneurological dyspnea, toxic dyspnea and hematogenous dyspnea. The dyspnea of ​​rheumatic heart disease is caused by valvular heart disease leading to long-term or rapid pulmonary congestion, decreased alveolar elasticity, ventilation dysfunction, decreased cardiac output, slowed blood flow, ventilation dysfunction, etc., which lead to hypoxia, carbon dioxide retention and increased pulmonary circulation pressure, causing increased excitability of the reflex respiratory center.

2. Chest pain:

Chest pain is a common symptom that can be caused by a variety of reasons. Sometimes it originates from minor local damage and is therefore unimportant, while sometimes it is caused by visceral diseases and is often of great significance. According to the origin of chest pain, it can be divided into chest pain caused by chest wall lesions, chest organ diseases, and other reasons. Chest pain caused by heart disease is called cardiac chest pain. This includes angina pectoris caused by rheumatic heart valve disease and chest pain caused by damage to the chest cavity or pericardium.

Syncope (fainting)

It is a sudden, brief loss of consciousness due to a temporary, widespread lack of blood supply to the brain. Main causes: reduced cardiac output (aortic valve disease) or cardiac arrest (conduction block), sudden and drastic drop in blood pressure (massive aortic valve regurgitation) or general temporary occlusion of cerebral blood vessels (thrombus detachment). Severe cases of cardiogenic syncope are called acute cardiogenic ischemic syndrome (Adams-stokes Syndrome).
