•Preprocedural malnutrition is associated with poor all-cause mortality.•The geriatric nutritional risk index is a simple and established method.•Coexisting cancer is another important predictor for all-cause death.•Assessing the nutritional status in advance is important for risk stratification.•Improving the nutritious status may be an option for managing these patients. Malnutrition is associated with a poor prognosis in heart failure, angina pectoris, and peripheral artery disease. However, the clinical importance of the preprocedural nutrition status of patients requiring pacemaker implantation (PMI) for bradycardia is unclear. We retrospectively enrolled 521 patients (median 79 years) who underwent their first PMI between January 1, 2012 and June 30, 2017. The nutrition status before implantation was assessed by the geriatric nutritional risk index (GNRI). The association between the preprocedural GNRI-based nutritional status and all-cause mortality was investigated. GNRI-based high (GNRI
