  • Title: Hemodynamic and angiocardiographic changes following nitroglycerin in coronary artery disease.
    Author: Suarez de Lezo J, Carrasco JL, Núñez P, García E, Hernandez-Lattuf P.
    Journal: Eur J Cardiol; 1977 Jun; 5(4):357-72. PubMed ID: 408139.
    Abstract:
    33 patients with suspected coronary artery disease were studied hemodynamically and angiocardiographically in the resting state and following administration of 0.4 mg of sublingual nitroglycerin (NTG). After NTG several parameters were changed: LVEDP, mean LV systolic pressure, EDVI, ESVI, SVI and SWI were decreased; EF, mean Vcf, MNSER, heart rate (P less than 0.01; r = 0.801) and chords, hemichords and shortening of long axis were increased. However, the changes after NTG were markedly different in patients with diffuse and localized LV asynergy, suggesting a more important inotropic effect of NTG in patients with localized LV asynergy, while reduction in venous return and EDV would be the main effect of NTG in patients with diffuse LV asynergy.
