Therapy combining vasodilators and inotropic agents is considered to be one of the most powerful means of improving cardiac function in patients with congestive heart failure (CHF). The vasodilators enhance the effectiveness of inotropic agents by providing a reduction in preload and/or afterload. Inotropic drugs with different mechanisms of action, such as digitalis glycosides, ephedrine, dopamine, dobutamine, ibopamine, terbutaline, salbutamol, pirbuterol, prenalterol, amrinone, and milrinone, have been tested in combination with vasodilators with a predominant effect on preload (nitrates, molsidomine), with a predominant effect on afterload (hydralazine, nifedipine), or with a balanced action on both arterial and venous beds (nitroprusside, prazosin, captopril), showing positive results. The problem of the combination of digitalis glycosides and vasodilators with different sites of action has been considered by our group. In 42 patients with CHF, digoxin (DIG, 0.01 mg/kg intravenously) was tested in combination with molsidomine (MLS, 4 mg sublingually) (12 patients), a nitrate-like agent with a predominant vasodilating action on the capacitance vessels, nifedipine (NFP, 10 mg sublingually) (22 patients), a Ca2+ antagonist drug with a predominant action on the resistance vessels, and captopril (CPT, 25 mg orally) (8 patients), an ACE inhibitor with a balanced effect on both preload and afterload. The combination DIG plus MLS caused a reduction in left ventricular filling pressure (LVFP) greater than that achieved with either agent alone. The hemodynamic improvement was obtained without side effects, in spite of the striking fall in preload. We stress that this investigation was performed on patients with CHF following acute myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

The DERMatology INFOrmation NETwork (DERM/INFONET) of the American Academy of Dermatology has become a reality. DERM/INFONET consists of a number of data bases providing information and educational programs for the dermatologist. Currently the components are: DERM/MLS (Medical Literature Search), DERM/RX (dermatologic therapy), DERM/USP (United States Pharmacopeia data base), DERM/ALLERGENS (Food and Drug Administration and Environmental Protection Agency Listings of allergens); Melanoma Prognosis Model; Electronic Mail; Bulletin Board; Meetings Calendar; ICD/CPT (International Classification of Diseases/Current Procedural Terminology) codes; AAD Membership/Committee Directories; and Dermatology Quiz. Additional data bases are planned. As audiovisual and alphanumeric communication systems evolve, newer opportunities for enhancing the DERM/INFONET Biomedical Communication Network will undoubtedly provide even greater opportunities for aiding the dermatologist in delivering state-of-the art management for their patients.
