Abstract:
Immunoglobulin G4-related disease (IgG4-RD) is an insidiously progressive multiorgan disease. However, lack of familiarity with IgG4-RD results in patients often being undiagnosed and undertreated. IgG4-RD can affect any organ, and manifests as aortitis within the cardiovascular system. Cardiac involvement is less common, and myocardial infarction is rarely reported. We report the first case of a patient with multiple myocardial infarctions caused by recurrent stent thrombosis associated with IgG4-RD, which resolved upon treatment of IgG4-RD. This case highlights the importance for cardiologists to consider IgG4-RD as a rare but possible association with stent thrombosis.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
