Effects of isosorbide dinitrate and nitroglycerin on central circulatory dynamics in coronary artery disease

Battock, Dennis J., Levitt, Peter W., Steele, Peter P.·1976·American Heart Journal

Abstract

This study compares the effects and duration of the effects of 5 mg. of sublingual (SL) isosorbide dinitrate (ISD), 20 mg. of oral ISD, and 0.4 mg. of SL nitroglycerin (TNG) on central circulatory dynamics. Twenty-seven patients with coronary artery disease were evaluated with radioisotope techniques and determinations made of heart rate (HR), blood pressure (BP), cardiac index (CI), stroke volume index (SVI), left ventricular enddiastolic volume index (LVEDVI), and left ventricular ejection fraction (LVEF). There were significant and equivalent reductions in BP, SVI, LVEDVI, and CI 15 minutes after TNG, 1 hour after SL ISD, and 4 hours after oral ISD in addition to comparative increases in HR and EF by all drugs at these same time intervals. The effects of TNG were gone at 30 minutes while changes in LVEDVI, LVEF, and CI were present 4 hours after SL ISD and persistent changes in LVEDVI and SVI present 6 hours after oral ISD. We conclude that nitrates have significant effects on both preload and afterload and that the duration of effects of sublingual and oral ISD are truly long acting as compared to TNG.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
