Modern society has led to the advancement of technology, which has increasingly infiltrated nursing practice. The nursing profession is conceived as an interaction between two categories of people, professionals in their field of work and patients as clients, ie consumers, and expertise. Modern advances in cardiology and nursing have increased the number of different examinations, the number of hospitalizations, the survival rate of patients, and the overall quality of their lives. The quality of work and the speed of care for cardiac patients is incomparably increased, thereby exercising their fundamental right from the spectrum of patients' rights, which is that of safety. but there is occasional alienation from patients, lack of communication and emotional support While decades ago, the nursing profession was based on a relationship of trust with the patient, over the past two decades, a technique conceived of as an "assistant to the profession" became increasingly involved in harmonious interaction. With the advent of the technique, there was a need to open intensive beds with fewer beds intended for hemodynamically unstable and life-threatening patients. The impact of technology on the quality of nursing care can be illustrated by examples from the practice of invasive cardiac procedures. The changes that are taking place today in the system of invasive cardiac procedures are related to the introduction of automation, computerization, definition of professional standards, good cardiology practice and good nursing practice. All these changes are necessary in order to introduce quality assurance and quality management systems, as a basic prerequisite for increasing the safety of invasive cardiologically treated patients. It is a true art to harmonize the principle of efficiency and effectiveness of the quality system of health care of invasive cardiologically treated patients, that is, to achieve an optimal relationship between the positive effects obtained from the performed health procedures and the costs incurred. The principle of cardiac patient orientation indicates that the starting point of all invasive cardiac activities is the patient's well-being, but there is always a real limitation in terms of staffing, technical, organizational and all other factors.
