Arteriosclerosis is diagnosed, mainly on the basis of family and medical history, in which case a physical examination and specific tests are performed, which include: blood tests, Doppler ultrasound, electrocardiogram, chest X-ray, echocardiography, angiography and stress test, etc. The study was conducted at the University Clinical Center of Kosovo (UCCK). The paper is based on data obtained from the research protocol of patients of this clinic, in the period 2016-2018. This study included 100 patients with heart disease and their treatment, with special emphasis on coronary artery bypass grafting. Our goal was to emphasize the care, as well as the quality of life of patients, after coronary artery bypass surgery. This process has always been supervised by the head nurse of the clinic, in order to fully preserve the privacy of the patients included in this research. From the results of this research, we found that males dominate in the number of patients included in the study, age over 50 dominates, and we also found that most patients have relatives who suffer from heart disease. We also see that 18% of patients continue to smoke after surgery, while 70% of them stated that their health after surgery is much better than last year, and
