Sudden cardiac death, either due to ventricular arrhythmias or complete heart block is a rare complication of cardiac sarcoidosis. [42] [43] Cardiac sarcoidosis can cause fibrosis, granuloma formation, or the accumulation of fluid in the interstitium of the heart, or a combination of the former two.
Löfgren syndrome is a type of acute sarcoidosis, [1] an inflammatory disorder characterized by swollen lymph nodes in the chest, tender red nodules on the shins, fever and arthritis. [2] It is more common in women than men, and is more frequent in those of Scandinavian , Irish , African and Puerto Rican heritage.
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.
Sarcoidosis: Cardiac sarcoidosis involves the formation of granulomas (clusters of inflammatory cells) within the heart tissue, which can lead to chest pain due to inflammation and fibrosis [39] Lead poisoning : Chest pain associated with lead poisoning may result from its impact on the cardiovascular system, including hypertension or vascular ...
As a consequence of reduced blood flow through the heart, there is an elevation in filling pressures, aimed at sustaining optimal blood circulation throughout the body. However, the excessive use of diuretics may lead to inadequate blood perfusion in body tissues and, consequently, tissue hypoperfusion due to a reduction in overall blood volume.
Other symptoms due to sarcoidosis of other organs may be uveitis (inflammation of the uveal layer in the eye), dyspnoea (shortness of breath), arthralgia (joint pains), lupus pernio (a red skin rash, usually of the face), erythema nodosum (red skin lumps, usually on the shins), and symptoms of liver involvement or heart involvement (heart failure).
Pulmonary hypertension is defined as a mean PAP of at least 20 mm Hg (3300 Pa) at rest, and PAH is defined as precapillary pulmonary hypertension (i.e. mean PAP ≥ 20 mm Hg with pulmonary arterial occlusion pressure [PAOP] ≤ 15 mm Hg and pulmonary vascular resistance [PVR] > 3 Wood Units). [58]
Causes of Kerley B lines include pulmonary edema, lymphangitis carcinomatosa and malignant lymphoma, viral and mycoplasmal pneumonia, interstitial pulmonary fibrosis, pneumoconiosis, and sarcoidosis. They can be an evanescent sign on the chest x-ray of a patient in and out of heart failure.
