Farhangi MA, et al. - Researchers examined how dietary acid load and cardiometabolic risk factors are associated with 10-year survival among 454 patients undergoing CABG surgery. Using the data obtained from a semi-quantitative food frequency questionnaire, they measured dietary acid load as either potential renal acid load (PRAL) or net endogenous acid production (NEAP). They observed lower BMI and lower ejection fraction rate among patients in the higher PRAL and NEAP quartiles. Further, patients of higher PRAL quartiles exhibited lower hematocrit values. They observed a higher mortality rate and reduced survival days in correlation with higher PRAL scores. These findings suggest the utility of high PRAL scores as positive predictors of 10-year mortality in patients who underwent CABG. The risk of mortality can be reduced by maintaining an adequate acid-base balance that may contribute to longevity.
