Among the risk factors for coronary artery disease, the most important is smoking. Another major risk factor for coronary artery disease is the smoke from tandoor ovens, to which many rural women are exposed over a period of years. Of 856 patients who underwent elective CABG surgery in our clinic between January 2011 and January 2017, 345 female patients were investigated retrospectively. The patients were divided into two groups: Group 1 (smokers, n=47) and Group 2 (tandoor bakers, n=91). The mean age was 59.4 ± 5.2 years for Group 1 and 62.3 ± 4.2 years in Group 2. The mean duration of extubation of the patients in intensive care unit was 5.4 ± 2.1 in Group 1, and 8.2 ± 2.4 hours in Group 2 (p <0.001). The average length of stay in the intensive care unit was 2.1 ± 1.5 days for Group 1 and 4.4 ± 2.2 days for Group 2 (p <.05). Chronic obstructive pulmonary disease is an independent risk factor for CABG. Aside from smoking, which frequently results in COPD, pulmonary functions are exacerbated in people (usually women) who bake using tandoor ovens. In these patients, the duration of postoperative intubation, length of stay in the intensive care unit and in the hospital are extended, and the need for Continuous Positive Airway Pressure (CPAP) machines in the intensive care unit increases. Therefore, women who use tandoor ovens should be considered high risk patients for CABG surgery, and these patients should be managed and followed up with caution.
