Recent studies suggest that nitric oxide (NO) plays an important role in nitrate-induced headache and in spontaneous migraine attacks. Organic nitrates act as prodrugs for NO and headache is a predominant adverse effect of nitrates but often disappears during continuous treatment. Insight into
Glyceryl trinitrate (GTN) is known to induce single extra attacks of cluster headache (CH) during active cluster periods, most probably via actions of nitric oxide (NO). Induction of whole periods of CH by organic nitrates has, however, attracted little attention in the literature. We report on
OBJECTIVE
The aim of the present study was to investigate the association between nitrate-induced headache (NIH) and the complexity of coronary artery lesions in patients with stable coronary artery disease (CAD).
METHODS
Two hundred and seventy-five patients with anginal chest pain who underwent
The aims of the present study were to investigate whether induction of nitrate tolerance is a useful treatment in cluster headache and to correlate any changes in attack frequency of cluster headache and nitrate-induced headache to the vascular adaptation during continuous nitrate administration.
BACKGROUND
Nitrates, although important for the management of angina pectoris, cause significant headache in many patients.
METHODS
In a randomized, double-blind, crossover study, 89 patients with stable angina pectoris were studied to compare two different dosage strategies of
BACKGROUND: Nitrates, although important for the management of angina pectoris, cause significant headache in many patients. METHODS: In a randomized, double-blind crossover study, 89 patients with stable angina pectoris were used to compare two different dosage strategies of
To assess whether serum creatinine and age are associated with headache induced by nitrates, 2742 hospitalized patients taking nitrates were studied during their hospital stay. Those patients with admission serum creatinine levels from 97 to 133 mumol/L and > 133 mumol/L were compared with patients
Treatment with ACE inhibitors has shown to be effective in the prophylaxis of migraine attacks. The aim of this study was to explore whether among hospitalized hypertensive patients use of ACE inhibitors may reduce the risk of headache caused by nitrates. To this end, we used the GIFA database, that
METHODS
A 34-year-old white male was executing blasting works in an operation of a quarry several times a month during a period of 1 year. Each time he worked with explosives, he complained of headache, vertigo and concentration failure which started shortly after beginning and continued several
A chronic anal fissure may be regarded as an ischaemic ulcer. Until recently, its treatment necessitated surgical intervention to lower the tension of the internal sphincter (lateral internal sphincterotomy), or manual dilatation of the anus. A disadvantage of both methods is the risk of permanent
