TOPIC: Critical Care TYPE: Fellow Case Reports INTRODUCTION: Vasopressin is commonly used to restore blood pressure in hyperdynamic hemodynamic states, thereby reducing catecholamine requirements. The effects of vasopressin are primarily caused by the rise mean arterial (MAP) due systemic vasoconstriction, which, depending on infusion rate, can also produce notable vasoconstrictive coronary mic...

Results Of the 1351 patients admitted with acute coronary syndrome, 28% had an elevation in the ST segment and 72% had no elevation. The patients with acute coronary syndrome with no elevation in the ST segment and no significant coronary obstruction were younger, predominantly females, and had a lower frequency of dyslipidemia, previous coronary arterial disease, diabetes mellitus, smoking, an...

RATIONALE ST-segment elevation localizes an ischemic lesion to the coronary artery supplying the area of the myocardium reflected by the electrocardiographic leads. Dynamic ST-segment elevation can be due to severe transmural ischemia secondary to a thrombus, vasospasm, or a tightly fixed coronary artery lesion or a combination of these situations. PATIENT CONCERNS In this study, we report on...

ventricular MI suppresses this ST segment elevation in the precordial leads and yields an ST segment elevation in leads II, III, and aVF.2-4 Massive STsegment elevation in precordial and inferior leads in RVMI has also been observed but is extremely rare.5 Thus, ST elevation in precordial leads should not exclude an infarction of the right ventricle that demands a treatment different from that ...
