RENTERIA-CABREJOS, María José et al. Factors associated with right bundle branch block in older adults. Rev Cub Med Mil [online]. 2022, vol.51, n.2 Epub 01-Jun-2022. ISSN 1561-3046.
Introduction:
There is little literature on the association between right bundle branch block and risk factors such as hypertension and diabetes in patients in Latin America and Peru.
Objective:
To determine the factors associated with right bundle branch block in older adults.
Methods:
Analytical cross-sectional study completed by 376 elderly patients treated at Almanzor Aguinaga Asenjo Hospital, Lambayeque-Peru. The dependent variable was the presence of right bundle branch block, and the independent variables were age, sex, history of hypertension, and diabetes. Prevalence ratios and 95 % confidence intervals were estimated.
Results:
Of 376 patients, the majority were male (55,9 %), the mean age was 75,6 years, 11,4 % had a history of hypertension and 9 % were diabetic; 41 % had a diagnosis of right bundle branch block. In simple regression, the frequency of right bundle branch block was 56 % (PR= 1,56; 95 % CI: 1,22-1,99), 65 % (PR=1,65; 95 % CI: 1,26 - 2,15) and 59 % (PR= 1,59; CI 95 %: 1,18 - 2,14) higher in women, hypertensive and diabetics; respectively. In the multiple regression; female sex (PR= 1,53; 95 % CI: 1,21 - 1,95), history of hypertension (PR= 1,55; 95 % CI: 1,21 - 2,00) and diabetes mellitus (PR= 1,49; 95 % CI: 1,12 - 2,00) were positively associated with right bundle branch block. The nested model selected the variables: female sex (PR= 1,54; 95 % CI: 1,21 - 1,96) and history of arterial hypertension (PR= 1,61; 95 % CI: 1,25 - 2,08).
Conclusion:
Female sex, history of arterial hypertension and diabetes mellitus were positively associated with presenting right bundle branch block in older adults.
