The part of the nervous system that regulates heart rate works differently in depressed people, and their abnormal platelets may cause arterial blockage.
This ostial extension, when severe, may cause arterial stenosis/occlusion, and consequently ischaemic changes in the respective organs [7] responsible for the symptoms cerebral ischaemic events, arterial hypertension, cardiac insufficiency and abdominal angina.
Angioectasia is a venous lesion that requires cauterization; Dieulafoy's lesions and arteriovenous malformations may cause arterial bleeding, and require clipping or surgical treatment.
Remifentanil, 1.0 to 4.0 μg·kg-1 combined with propofol, provides acceptable intubating conditions [ 1, 2, 4], but these doses may cause arterial hypotension and severe bradycardia [ 7, 8].
Inadvertent arterial injection, particularly when attempting to inject into the femoral vein, that is, "groin injecting," may cause arterial pseudoaneurysm (4, 5 ).
In addition to having the same side-effects as topical corticosteroids, they may cause arterial hypertension, electrolyte imbalance, impaired glucose metabolism, Cushing's syndrome, and osteoporosis, especially in long-term treatment.
An experimental study on humans indicated that inhalation of fine particulate air pollution and ozone may cause acute arterial vasoconstriction that could lead to cardiovascular events [ 24].
It highlights that 5-FU may have the potential to cause arterial vasospasm outside the cardiac vasculature, resulting in end-organ optic nerve ischaemia.
These effects in vivo would cause arterial dilation and hypotension.
However, due to the need for contrast media (that may cause renal toxicity, arterial wall dissection, emboli, fistulae, pseudoaneurysms, and access site complications) and to its inherent limitations (no careful hemodynamic study of the stenotic segment nor of its length (overestimated) is possible), the clinical use of DSA is currently limited (57).
This is not only inconvenient for patients, but interruption of an intravenous infusion may cause fatal rebound pulmonary arterial hypertension.
