Key result
Lower body mass index is inversely associated with adverse in-hospital outcomes (OR 0.95) and significantly longer length of stay following percutaneous coronary intervention.
Why the study?
The relationship between BMI and in-hospital length of stay after PCI had not been thoroughly investigated, especially in Bangladesh.
Does lower BMI (<23 kg/m2) increase in-hospital length of stay and adverse outcomes in patients undergoing percutaneous coronary interventions?

No
Does lower BMI (<23 kg/m2) increase in-hospital length of stay and adverse outcomes in patients undergoing percutaneous coronary interventions?
Lower BMI (<23 kg/m2) is associated with longer in-hospital length of stay and higher rates of adverse outcomes following PCI compared to higher BMI, supporting the existence of an 'obesity paradox'.
Background: In-hospital length of stay (LOS) is an important metric for assessing the quality of care and planning capacity within a hospital. Percutaneous Coronary Interventions (PCI) merit short LOS following an uncomplicated procedure. Various factors have been studied that may influence LOS. The relationship between BMI and LOS after PCI has not been thoroughly investigated, especially in Bangladesh. Methods: This cross-sectional observational study was conducted at National Institute of Cardiovascular Diseases, on total 100 patients who underwent PCI with two equally divided groups on the basis of BMI of Asian ethnicity: Group I (BMI < 23 kg/m2) and Group II (BMI e” 23.0 kg/m2). In-hospital outcomes and LOS were observed and recorded after PCI. Results: The mean BMI of study population was 23.9 ± 1.9 kg/m2. The sum of occurrence of adverse in-hospital outcomes was 14.0%. Complications were significantly (p < 0.01) higher in Group I than Group II. Among all adverse in-hospital outcomes, only acute left ventricular failure was found to be statistically significant between groups (p < 0.01). The difference of mean LOS after PCI was higher in Group-I which was statistically significant (p < 0.01). Diabetes mellitus and dyslipidemia were found to be the independent predictors for developing adverse in-hospital outcome (OR= 1.68 and 1.46; 95% CI = 1.25 – 2.24 and 1.16 – 1.83; p = 0.018 and 0.040, respectively). BMI was inversely associated with adverse in-hospital outcome after PCI (OR = 0.95; 95% CI = 0.91 – 0.98; p = 0.007). Conclusion: BMI is inversely associated with adverse in-hospital outcome after PCI. The underweight people are likely to experience longer LOS following PCI. Cardiovasc. j. 2020; 13(1): 19-26

Siddiqui et al. (2020) conducted a cross-sectional in Percutaneous Coronary Intervention (n=100). BMI < 23 kg/m2 vs. BMI ≥ 23 kg/m2 was evaluated on Adverse in-hospital outcomes (OR 0.95, 95% CI 0.91-0.98, p=0.007). Lower body mass index is inversely associated with adverse in-hospital outcomes (OR 0.95) and significantly longer length of stay following percutaneous coronary intervention.
