RESUMEN
Background There is a scarcity of studies delineating the trends of cardiovascular interventions in the hospitalized population stratified by body mass index (BMI). Our study aimed to study the burden of cardiovascular interventions and outcomes by BMI. Methods We retrospectively analyzed the Nationwide Inpatient Sample (NIS) database between January 2016 and December 2020. We identified the population of interest using the International Classification of Diseases, Tenth Revision (ICD-10) code. We studied the BMI in five categories: "healthy weight" (HW; BMI < 19.9-24.9 kg/m2), "overweight" (OV; BMI = 25-29.9 kg/m2), "obesity class one" (OB1; BMI = 30-34.9 kg/m2), "obesity class two" (OB2; BMI = 35-39.9 kg/m2), and "obesity class three" (OB3; BMI > 40 kg/m2). Results There were 5,654,905 hospitalizations with an ICD-10 code related to BMI within this study period. The HW group had 1,103,659 (19.5%) hospitalizations, the OV group had 462,464 (8.2%), the OB1 group had 1,095,325 (19.4%), the OB2 group had 1,036,682 (18.3%), and the OB3 group had 1,956,775 (34.6%) hospitalizations. The mean age of the population with obesity was as follows: OB1 = 61 years (SD = 16); OB2 = 58 years (SD = 15.9); and OB3 = 55 years (SD = 15.5). The mean ages of the HW and OV groups were 68 years (SD = 16.6) and 65 years (SD = 16.1), respectively. In the HW group, there were 948 (8.1%) hospital admissions for aortic valve replacement (AVR), 54 (11%) for aortic valve repair (AVRr), 737 (15.9%) for mitral valve replacement (MVRr), 12 (17.1%) for mitral valve repair (MVR), 79 (2.2%) for left atrial appendage (LAA) closure, and 3390 (5.2%) for percutaneous coronary intervention (PCI). The OV group had 1049 (8.9%) hospital admissions for AVRs, 42 (9%) for AVRr, 461 (10%) for MVRr, four (5.7%) for MVR, 307 (8.6%) for LAA closure, and 5703 (8.8%) for PCIs. The OB1 group had 3326 (28.4%) hospital admissions for AVR, 125 (26.9%) for AVRr, 1229 (26.7%) for MVRr, 23 (32.9%) for MVR, 1173 (32.9%) for LAA, and 20,255 (31.3%) for PCI, while the OB2 group had 2725 (23.3%) hospital admissions for AVR, 105 (22.6%) for AVRr, 898 (19.4%) for MVRr, 11 (15.7%) for MVR, 933 (26.2%) for LAA, and 16,773 (25.9%) for PCI. Lastly, the OB3 group had 3626 (31%) hospital admissions for AVR, 139 (29.9%) for AVRr, 1285 (27.8%) for MVRr, 20 (28.6%) for MVR, 1063 (29.9%) for LAA, and 18,589 (28.7%) for PCI. Conclusion Our study supports the evidence of increased cardiovascular interventions with increasing BMI. Albeit, an inconsistent presentation across the spectrum of cardiovascular diseases and outcomes, for example, equal or better outcomes in obese cohorts compared to the healthy weight population undergoing PCI. However, the increasing cardiovascular intervention burden in the youngest studied population suggests a rise in the cardiovascular disease burden among the young and partially explains their better outcomes. Steps to include weight management for these patients are paramount.
RESUMEN
Background Chronic steroid use is debilitating to health, but, in some cases, it is necessary. We examined the effect of chronic steroid use on the discharge disposition of people undergoing transcatheter aortic valve replacement (TAVR). Methods We queried the National Inpatient Sample Database (NIS) from 2016 to 2019. We identified patients with current chronic steroid use with the International Classification of Diseases for the Tenth (ICD-10) code Z7952. Furthermore, we used the ICD-10 procedure codes for TAVR 02RF3. Outcomes were the length of hospitalization (LOS), Charlson Comorbidity Index (CCI), disposition, in-hospital mortality, and total hospital charges (THC). Results Between 2016 and 2019, we identified 44,200 TAVR hospitalizations, and 382,497 were on current long-term steroid therapy. Of these, 934 had current chronic steroid use and underwent TAVR (STEROID) with a mean age of 78 (SD=8.4). About 50% were female, 89% were Whites, 3.7% were Blacks, 4.2% were Hispanics, and 1.3% were Asians. Disposition was 'home,' 'home with home health' (HWHH), 'skilled nursing home' (SNF), 'short-term inpatient therapy' (SIT), 'discharged against medical advice' (AMA), and 'died.' A total of 602 (65.5%) were discharged home, 206 ( 22%) were discharged to HWHH, 109 (11.7%) to SNF, and 12 (1.28%) died. In the SIT and AMA groups, there were only three and two patients, respectively, p=0.23. The group that underwent TAVR and was not on chronic steroid therapy (NOSTEROID) had a mean age of 79 (SD=8.5), with 28731 (66.4%) being discharged home, 8399 (19.4%) to HWHH, 5319 (12.3%) to SNF, and 617 (1.43%) died p=0.17. Comparing the STEROID vs. NONSTEROID group, according to the CCI, the STEROID group scored higher than the NOSTEROID group; 3.5 (SD=2) vs. 3 (SD=2) p=0.0001, while for LOS, it was 3.7 days (SD=4.3) vs. 4.1 days (SD=5.3), p=0.28, and the THC was $203,213 (SD=$110,476) vs. $215,858 (SD=$138,540), p=0.15. Conclusion The comorbidity burden of individuals on long-term steroids undergoing TAVR was slightly higher than those not on steroids undergoing TAVR. Despite this, there was no statistically significant difference in their hospital outcomes following TAVR with respect to dispositions.
