We investigated the treatment of 146 men, mean age 62 years, and 54 women, mean age 69 years, with acute ST-segment elevation myocardial infarction (STEMI) in a university medical center. Coronary revascularization or thrombolytic therapy was given to 143 men (98%) and 52 women (96%) [P = not significant (NS)]. Antiplatelet therapy and antithrombotic therapy were given to 146 men (100%) and 54 women (100%) (P = NS).

Fasting plasma insulin concentrations were obtained in 82 patients (51 men and 31 women), mean age 60 +/- 11 years, with a body mass index >25 kg/m(2) who had coronary angiography because of suspected symptomatic coronary artery disease (CAD). Obstructive CAD was diagnosed if there was >50% obstruction of > or =1 vessel. Of 82 patients, 37 (45%) had left main or 3-vessel CAD, 22 (27%) had 2-vessel CAD, 9 (11%) had 1-vessel CAD, and 14 (17%) had no obstructive CAD.

The effect of an ongoing educational program on the use of cardiovascular drugs in patients with coronary artery disease without contraindications to these drugs seen in an academic cardiology clinic was assessed in 100 patients seen during the 6-month period prior to the educational program and in 200 patients seen 9 to 20 months after the onset of the educational program. Following the educational program, the use of aspirin, clopidogrel, or warfarin increased from 69 to 99%, the use of beta- blockers increased from 57 to 98%, the use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers increased from 41 to 97%, and the use of lipid-lowering drugs in patients with dyslipidemia increased from 54 to 98% in patients without contraindications to these drugs.
