Abstract
The frequencies of the annual main cadiovascular procedures performed in each hospital must be a index of the grade showing hospital activities. The proper frequencies are, as well, basal condition to maintain highly trained medical and surgical skills. Annual case number of 80 for PTCA for a medical and 80 for CPB for a surgical team are minimal demands.
This investigation revealed that disordered overflooding of hospitals for cardiovascular specialities resulted in deterioration of clinical qualities. The deterioration were exposed in dissatisfaction of facilities, equipments, man-powers and consequently cardiac-special achievements in almost all hospitals but universities.
Proper arrangement of hospitals in regard to the regional population is essential to secure proper case numbers. One cardiovascular hospital is thought to be suitable for one million of regional population. This could be induced only after political guide.
The interventional medical procedures, such as PTCA, should be restricted in the hospitals which have both medical and surgical team. Each medical and surgical team are expected to have two specialists and two trainee-specialists at least. Immediate increase in number of nurse-specialists in ICU, found to be less than half compared to standard in this series, has principal importance of high-grade practice.
