This case report highlights the potential for intravenous diazoxide to induce myocardial ischemia in patients treated for severe hypertension, likely due to rapid blood pressure reduction and reflex tachycardia.
Answers are grounded in this paper and cite their sources.
May warrant caution for ischemia with IV diazoxide in severe hypertension; single case leaves open systematic safety evaluation.

They postulate that the rapid fall in blood pressure and resulting regional decrease in coronary blood flow in patients with obstructive coronary artery lesions was responsible. A reflex tachycardia after drug administration may be important in some instances. A 62-year-old white woman was normotensive 1 year before admission but became hypertensive during the year. She came to the emergency room having had headaches and vomiting for 3 days....References1. KANADAKANADAHUTCHINSON SDR: Angina-like syndrome with diazoxide therapy for hypertensive crisis.
