Nitroglycerin-induced migraine type headache: bilaterally visible temporal arteries
A 37-year-old man presented to the emergency department suffering from headache, nausea and vomiting, which had started 1 h previously. He had been diagnosed with coronary artery disease and had been taking isosorbid-5-mononitrate, aspirin and metoprolol for 3 days. His vital signs and physical and detailed neurological examinations were normal except for a new onset of bilaterally visible, pal...
متن کاملNormobaric hypoxia and nitroglycerin as trigger factors for migraine.
Migraine prevalence is increased in high-altitude populations and symptoms of acute mountain sickness mimic migraine symptoms. Here we tested whether normobaric hypoxia may trigger migraine attacks. As positive control we used nitrolgycerin (NTG), which has been shown to induce migraine attacks in up to 80% of migraineurs. Sixteen patients (12 females, mean age 28.9 +/- 7.2 years) suffering fro...
متن کاملBlood sugar response to glucagon in migraine.
The hyperglycaemic response to intramuscular glucagon was studied in 19 migraine subjects and 17 matched controls. Venous blood sugar 30 minutes after the injection, and the maximum rise from fasting levels, were significantly reduced in migraine subjects. This diminished sensitivity to the hyperglycaemic action of glucagon may be at least one factor in the hypoglycaemia unresponsiveness shown ...
متن کاملTherapy with nitroglycerin increases coronary vasoconstriction in response to acetylcholine.
OBJECTIVES The purpose of this study was to investigate whether therapy with nitroglycerin (GTN) would lead to abnormal coronary artery responses to the endothelium-dependent vasodilator acetylcholine. BACKGROUND Nitroglycerin therapy is associated with specific biochemical changes in the vasculature that may lead to increased vascular sensitivity to vasoconstrictors. METHODS Patients were ...
متن کاملSignificance of the nitroglycerin-flicker fusion response in normal subjects and patients with cardiovascular disease.
The Krasno-Ivy nitroglycerin-flicker fusion test was carried out in normal persons, and in patients with arterial hypertension and/or coronary disease. A positive test was obtained more often in patients with cardiovascular abnormalities than in normal individuals. In the former group the frequency of negative results and the inconstancy of response to multiple tests indicate the unrelia-bility...
