The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an overload in chronic pressure.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production and/or exacerbations) due to abnormalities of the airways (bronchitis ...
Right-sided heart failure is often caused by pulmonary heart disease (cor pulmonale), which is typically caused by issues with pulmonary circulation such as pulmonary hypertension or pulmonic stenosis. Physical examination may reveal pitting peripheral edema, ascites, liver enlargement, and spleen enlargement.
Preventing Cardiovascular Disease. The development of cardiovascular disease is strongly associated with your lifestyle habits. You can minimize your chances of developing cardiovascular disease by:
The low oxygen level leads to physiologic constriction of the pulmonary arteries to correct ventilation-perfusion mismatching, which puts excessive strain on the right side of the heart. When this leads to right sided heart failure, it is known as cor pulmonale. [4]
Common causes include pulmonary hypertension, which can be the primary defect leading to RAE, or pulmonary hypertension secondary to tricuspid stenosis; pulmonary stenosis or Tetralogy of Fallot i.e. congenital diseases; chronic lung disease, such as cor pulmonale.
Life expectancy may be plateauing. Don’t expect your grandkids to live to 200 years old. A study published on Monday suggests we may be reaching our limit in terms of life expectancy and that ...
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
