Data on the characteristics and outcomes of hospitalized patients with aortic aneurysms (AA) and HIV remain scarce. This is a cohort study of hospitalized adult patients with a diagnosis of AA from 2013 to 2019 using the US National Inpatient Readmission Database. Patients with a diagnosis of HIV were identified. Our outcomes included trends in hospitalizations and comparison of clinical characteristics, complications, and mortality in patients with AA and HIV compared to those without HIV. Among 1,905,837 hospitalized patients with AA, 4416 (0.23%) were living with HIV. There was an overall age-adjusted increase in the rate of HIV among patients hospitalized with AA over the years (14–29 per 10,000 person-years; age-adjusted p-trend < 0.001). Patients with AA and HIV were younger than those without HIV (median age: 60 vs 76 years, p < 0.001) and were less likely to have a history of smoking, hypertension, dyslipidemia, diabetes mellitus, and obesity. Thoracic aortic aneurysms were more prevalent in those with HIV (37.5% vs 26.7%, p < 0.001). On multivariable logistic regression, HIV was not associated with increased risk of aortic rupture (OR: 0.79; 95% CI: 0.61–1.01, p = 0.06), acute aortic dissection (OR: 0.73; 95% CI: 0.51–1.06, p = 0.3), readmissions (OR: 1.04; 95% CI: 0.95–1.13, p = 0.4), or aortic repair (OR: 0.89; 95% CI: 0.79–1.00, p = 0.05). Hospitalized patients with AA and HIV had a lower crude mortality rate compared to those without HIV (OR: 0.75 (0.63–0.91), p = 0.003). Hospitalized patients with AA and HIV likely constitute a distinct group of patients with AA; they are younger, have fewer traditional cardiovascular risk factors, and a higher rate of thoracic aorta involvement. Differences in clinical features may account for the lower mortality rate observed in patients with AA and HIV compared to those without HIV.

Introduction: Periodontal disease (PD) is an acquired disorder characterized by inflammation of the gums, resulting eventually in loss of teeth. Epidemiological studies have shown a link between PD and cardiovascular diseases (CVDs). The aim of this study is to evaluate differences in the prevalence of CVD amongst US patients with PD of different age, race and sex. Method: Using the US national in-patient sample database (NIS) from 2005-2014, patients with PD and CVD were identified. Results: 155,732 hospitalizations with PD were included in the study, of which 36.5% had at least one CVD. Ischemic heart disease was the most prevalent CVD (17.6%), followed by heart failure (10.9%), atrial fibrillation/flutter (10.1%) and cerebrovascular disease (CRVD) (9.7%). The overall in-hospital mortality was higher in PD patients with CVD (2.6% vs 1.2%, p<0.0001). Figure 1C highlights the prevalence of various subtypes of CVD among different gender. When stratifying hospitalized patients with PD and CVD based on race and age, there was higher prevalence of CVD among Asians and Pacific Islanders (42.4%) (Figure 1A-B) and with increasing age (≥70, 56-69, and 18-55; 67.4% vs 50.1% vs 20.3%, p<0.001, respectively). Significant increase trends in the prevalence of AF, HF, and CRVD in the young, middle, and older age group was noted (P-trend<0.001) (Figure1A). Conclusion: CVD is prevalent in patients with PD and is more common in males and among Asians and Pacific Islanders. Higher mortality was reported among hospitalized PD patients with CVD. An increase in trend in the prevalence of AF, HF, and CRVD was noted across all age groups. This may require age, race, and gender specific strategies in PD patients for primary prevention of different CVD.
