Acute aortic dissection on CT: is D-dimer determination useful for a timely and correct diagnosis? A case report.

Background: Chest pain is a common reason patients are admitted to the hospital. The most clinically significant cases are those in which the pain is due to an immediate life-threatening condition, such as acute aortic dissection (AAD). A prompt and correct diagnosis is crucial to patient survival.

Use of levosimendan in the treatment of cerebral vascular vasospasm: a case study.

Despite the progress in the management of cerebral arterial aneurysms, subarachnoid hemorrhage (SAH) remains the major cause of neurological disability. While SAH-related deaths usually occur as a result of brain impairment due to hemorrhage, permanent neurological deficits are caused by cerebral ischemia due to edema and spasm of cerebral arteries. Additionally, ~20%-30% of patients with SAH develop secondary cardiomyopathy; this phenomenon is known as neurogenic stress cardiomyopathy (NSC), which is associated with increased mortality and poor long-term prognosis.
