A prospective study was made of sequential changes in serum creatine kinase (CK) and CK-MB isoenzyme activity within the 12 hours following admission to the coronary care unit on 65 patients with recent chest pain. CK determinations were performed in the laboratory or in the coronary care unit using a dry reagent strip analyser. Slope values for log CK/hour and log CK-MB/hour were calculated, u...

The time of onset of chest pain was studied prospectively in 1154 consecutive patients admitted to a coronary care unit with myocardial infarction during a five year period. Statistical analysis confirmed a previous finding in a retrospective study of a bimodal frequency distribution with peaks in the time of onset of chest pain between 2330 and 0030 hours and between 0630 and 0830 hours. Many ...

This report is an analysis of deaths that occurred in the Coronary Care Unit within a 3 year period. Forty percent of 304 patients (13 percent) unth. acute myocardial infarction died in the Coronary Care Unit, Fifty percent of the deaths were due ...

The potential value of thallium-201 scintigraphy as a means of selecting patients for appropriate coronary care unit admission was evaluated. Studies were made prospectively on 203 patients with possible acute myocardial infarction but atypical history and non-diagnostic electrocardiogram at a time when the clinical diagnosis was still in doubt. Under conventional circumstances, this particular...

The concept of specialized cardiovascular care is not new. Nearly 4 decades ago, Killip and Kimball1 reported the results of their study of the treatment of 250 patients with myocardial infarction in a coronary care unit. With continuous ECG monitoring at a centralized nursing station, defibrillators at each bedside, and nurses authorized to deliver precordial shocks if physicians did not respo...
