Association between preoperative physical activity on pulmonary function and post pulmonary complications in patients undergone CABG surgery - Cohort study

Worldwide approximately 2 million heart surgeries done, Although CABG surgery is an effective coronary revascularization technique associated with decrease pulmonary function. Also post pulmonary complications are the main cause of morbidity and mortality in patients undergoing CABG surgery which prolong intensive care unit stay .So this study determine how patients physical activity prior to surgery can impact on respiratory function and development post pulmonary complications also identify whether increased physical activity prior to surgery corelates with better pulmonary function and reduced post pulmonary complications.

Null hypothesis - There will be no significant association between preoperative physical activity on pulmonary function and post pulmonary complications anong individuals under hone CABG survey.

Alternate hypothesis - There will be significant association between preoperative physical activity on pulmonary function and post pulmonary complications among patients undergone CABG surgery.
