Is there relationship between obesity and early postoperative survival after off-pump CABG?

The article studies and analyzes the prevalence of excess body weight and obesity in patients with coronary artery disease, as a leading medical and biological risk factor for the development of diseases of the circulatory system. The presence of obesity is associated with such concomitant diseases as arterial hypertension, dyslipidemia, type II diabetes. The relationship of excess body weight and obesity with 30-day postoperative mortality, age and gender of patients was analyzed. The body mass index was determined and its value was interpreted in relation to the presence of excess body weight and obesity. It was established that in the sample of patients with coronary heart disease, the average height was 172.3 cm, the average body weight was 81.9 kg; the average value of the body mass index is 29.7 (variations of the body mass index from 18.3 to 44.9). As a result of the analysis of the received data, a high prevalence of excess body weight (45.5%) and obesity (40.1%) among patients with coronary artery disease was found. It was found that among male patients, normal body weight (χ²=8.26; p=0.004) and excess body weight (χ²=66.25; p=0.0001) were significantly more common, compared to female patients. And obesity (χ²=42.49; p=0.0001) and severe obesity (III degree), (χ²=4.21; p=0.04) were significantly more common among female patients. It was found that patients with normal body weight were 3.1 years older, which is reliable relative to obese patients (χ²=25.83; p=0.0001). It was determined that the highest frequency of 30-day mortality was observed in patients with normal body weight (1.1%), while in obese patients the corresponding frequency was 0.6%. It was found that deceased patients with normal body weight were significantly older than deceased patients with obesity (χ²=13.63; p=0.0001) and deceased patients who had excess body weight (χ2=6.10; p=0.01).
