Introduction
Cardiogenic pulmonary edema refers to a condition in which patients, affected by heart diseases, accumulate excessive fluid in the alveolar walls and alveolar spaces. Symptoms vary depending on the pathological stage and this condition may be life-threatening. The pathogenesis of cardiogenic pulmonary edema is due to impaired systolic or diastolic function of the left ventricle.
Cardiogenic pulmonary edema refers to a condition in which patients, affected by cardiac diseases, develop an excessive accumulation of fluid in the alveolar walls and alveolar spaces. Depending on the pathological stage, symptoms may vary. This condition can be life-threatening.
The pathogenesis of cardiogenic pulmonary edema is due to impaired systolic or diastolic function of the left ventricle, leading to persistently elevated pressure in the left coronary artery. This increased pressure causes continuous leakage of fluid through the capillary membranes in the lungs, which then spreads into the alveolar walls and alveolar spaces. Common underlying causes include coronary atherosclerotic heart disease, hypertrophic cardiomyopathy, and congestive heart failure. Patients often experience symptoms such as chest tightness, chest pain, and dyspnea (shortness of breath).
If patients experience the aforementioned adverse symptoms, they should seek medical evaluation at a hospital as early as possible for thorough diagnostic testing. Once the exact cause is identified, treatment should be carried out according to medical guidance and standardized protocols.
