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.
An ECG may show signs of right heart strain or acute cor pulmonale in cases of large PEs – the classic signs are a large S wave in lead I, a large Q wave in lead III, and an inverted T wave in lead III (S1Q3T3), which occurs in 12–50% of people with the diagnosis, yet also occurs in 12% without the diagnosis.

When taking into account complications including cor pulmonale and pulmonary hypertension, the levels involved are 56–59 mmHg. [178] Oxygen therapy is to be used for between 15 and 18 hours per day and is said to decrease the risk of heart failure and death. [178]
Generally, pleurisy treatment has an excellent prognosis, but if left untreated it can cause severe complications. For example, a resulting [citation needed] pulmonary heart disease, cor pulmonale, which manifests itself in an inflammation of the arms and legs, can lead to heart failure. If the conditions that caused the pleurisy or other ...
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.
Complications: Worsening of or causing heart failure and/or heart block, serious arrhythmias such as ventricular fibrillation, cor pulmonale, respiratory or kidney or liver dysfunction or failure, multiple organ dysfunction syndrome, cardiac arrest, death: Causes: Heart attack, myocarditis, endocarditis, certain medications and substances [2 ...
Lower airway obstruction, often from chronic diseases, has various complications: Chronic Hypoxia: Prolonged obstruction reduces oxygen supply. This leads to fatigue, confusion, and eventual organ damage. [1] (Harrison's Principles of Internal Medicine, 20th Edition). Cor Pulmonale: Persistent low oxygen levels can strain the right side of the ...
If fat globules obstruct 80% of the lung capillary network, the resulting back pressure on the right heart increases workload and causes right heart dilatation through cor pulmonale, leading to acute right heart failure. [5] Biochemical theory - Following trauma, an inflammation causes bone marrow to liberate fatty acids into the venous ...
