Cardiac emergencies.

Abstract

Learning to effectively treat cardiac emergencies is not an easy task. It is my opinion that mastery of material presented herein will ensure minimal competency. Finding practical experiences to help develop the necessary medical skills will require imagination and creativity. The following are offered as possible resources:1. Attend the American Heart Association's basis and advanced life support classes. (CPR training must be repeated at six-month intervals.) 2. Spend several days and/or nights in the emergency room at a local hospital observing (helping with(emergency care. #. Spend time with a mobile coronary care unit if available in your community. 4. Watch and do venipunctures at the local blood bank or donor center. 5. Observe in the intensive care unit at a local hospital. 6. Assist an oral surgeon in preparing intravenous lines and monitor a patient during sedation. 7. Observe administration of oxygen by an anesthesiologist in the operating room at a local hospital.

Effect of a hypoglycemic agent on ischemic preconditioning in patients with type 2 diabetes and stable angina pectoris.

OBJECTIVE: Ischemic preconditioning is an increased tolerance to myocardial ischemia during the second of two consecutive exercise tests. ATP-sensitive K(+) channel blockers, such as glinides and sulfonylurea drugs, can induce loss of ischemic preconditioning. This study aimed to investigate the effects of repaglinide, a hypoglycemic agent with an affinity for myocardial ATP-sensitive K (+)channels, on the results of consecutive exercise tests in patients with diabetes and multivessel coronary artery disease. METHODS: Forty-two patients with type 2 diabetes and chronic stable angina pectoris, and two-vessel or three-vessel disease participated in this study. The patients underwent two consecutive treadmill exercise tests (phase 1). On the day after these exercise tests, 2 mg of oral repaglinide was given to the patients. One week later, two exercise tests were repeated consecutively (phase 2). RESULTS: All patients achieved 1.0-mm ST-segment depression during the four exercise tests (T1, T2, T3, and T4). In phase 2, seven patients improved in time to onset of 1.0-mm ST-segment depression. The worsening of the time to onset of 1.0-mm ST-segment depression in phase 2 demonstrated ischemic preconditioning block in 83.3% of patients (P=0.0001). Even the postexercise electrocardiographic parameters (ST-segment depression morphology and magnitude and arrhythmias) were significantly different between the groups with and without pharmacologic ischemic preconditioning block (P=0.031). CONCLUSIONS: Repaglinide, an oral hypoglycemic agent with ATP-sensitive K(+) channel-blocker activity, eliminated the myocardial ischemic preconditioning in patients with coronary disease and diabetes.
