Thus, there are now several chronic canine myocardial infarction­ ventricular tachyarrhythmia models which are available for the evaluation of new antiarrhythmic drugs (Table I). The available models fulfill many, but not all of the requirements for an ideal chronic arrhythmia model (Table 11). The sustained arrhythmias initiated in these models using programmed pacing presumably have the same localized reentrant mechanism that characterizes c...

With the beginning of the 1980's it was becoming increasingly evident that the lack of approval of new cardiovascular agents for use by clinicians in the United States for the treatment of cardiovascular disorders was becoming a problem. Patients requiring medical therapy for hypertension, angina pectoris, arrhythmias, congestive heart failure, and vasospastic disorders of the coronary arteries could receive in the United States only a small n...

The Symposium on New Drugs provides a forum for academic investigators, research and development personnel from the pharmaceutical industry and members of the Food and Drug Administration to discuss important clinical research issues. The Ninth Annual symposium on New Drugs addressed the problem of determining the risk versus benefit for use of three important classes of cardiovascular agents: thrombolytic, antiarrhythmic, and hypolipidemic ag...

In Harch of 1980, we organized the first symposium on how to evaluate new antiarrhythmic agents in which the participants included members of the Cardio-Renal Division of the Food and Drug Administration, academic investigators from the United States and Abroad and directors and imple­ mentors of pharmacological research representing the pharmaceutical industry. By bringing together all three elements, it was hoped that better communication an...

Although some investigators have questioned the importance and even the existence of silent myocardial ischemia, documentation presented at this two day symposium leaves little doubt about its existence and importance. It has been estimated that about 3 million of the estimated 4 million angina sufferers in the United states have frequent episodes of silent myocardial ischemia. Although it is not possible to define how many Americans die due t...

In summary, there are many animal models that are useful in selecting new antiarrhythmic drugs. The selection of which model is most idea depends upon precisely what question is being asked. The large number of experimental models used to evaluate antiarrhythmic compounds points out the inability of anyone model to define the probability of antiarrhythmic efficacy in man. It has therefore become standard practice to utilize a batter of animal ...

In the 1980's a primary focus for intense cardiovascular research is in the treatment of patients with acute myocardial infarction. Although the prevalence of this syndrome has been decreasing in the United States, still over 1.5 million patients develop myocardial infarction per year. There is about a 20% chance of a North American male developing myocardial in­ farction before the age of 65. The in-hospital mortality still remains at ap­ pro...

The Symposium on New Drugs provides for an annual forum for academic investigators, research and development personnel from the pharmaceutical and related health care industries, and members of the Food and Drug Administration to discuss important clinical research issues. The Tenth Annual Symposium on New Drugs addressed the problem of whether it was still appropriate to approve antihypertensive agents soley on the endpoint of lowering cuff b...
