ABSTRACT

BACKGROUND: Meta-analyses have suggested the risk of cardiovascular disease (CVD) events is significantly higher after a chronic obstructive pulmonary disease (COPD) exacerbation. However, many of these studies have included a broad array of CVD events or have been limited to highly selected patient populations potentially not generalizable to the broader population of COPD. METHODS: We assessed the risk of atherosclerotic cardiovascular disease (ASCVD)hospitalizations after COPD hospitalization compared to before COPD hospitalization and identified patient factors associated with ASCVD hospitalizations after COPD hospitalization. This retrospective cohort study used claims data from 920,550 Medicare beneficiaries hospitalized for COPD from 2016-2019 in the US. The primary outcome was risk of a ASCVD hospitalization composite outcome (myocardial infarction, percutaneous coronary intervention, coronary artery by-pass graft surgery, stroke, or transient ischemic attack) in the 30-days and 1 year after-COPD hospitalization relative to the same time period before-COPD hospitalization. Time in the before- and after-COPD hospitalization time periods to a composite ASCVD hospitalization outcome were modeled using an extension of the Cox Proportional-Hazards model, the Anderson-Gill model with adjustment for patient characteristics. Additional analyses evaluated for interactions in subgroups associated with the composite ASCVD hospitalization outcome. RESULTS: Among 920,550 patients in the 30-day and 1-year cohorts, (mean age, 73-74 years) the hazard ratio estimate (HR; 95% CI) for the composite ASCVD hospitalization outcome after-COPD hospitalization vs before-COPD hospitalization for the 30-day cohort was 0.99 (0.93, 1.05; p = 0.67) and for the 1-year cohort was 0.99 (0.97, 1.02; p = 0.53) following adjustment. We observed 3 subgroups that were significantly associated with higher risk for ASCVD hospitalizations 1 year after COPD hospitalization: 76+ years old, women, COPD hospitalization severity. CONCLUSION: Among Medicare beneficiaries hospitalized for COPD, the risk of ASCVD hospitalizations was not significantly increased 30-day or 1-year after COPD-hospitalization relative to before-COPD hospitalization. In sub-group analyses, we identified age 76+ years old, female sex, and COPD hospitalization severity as high risk subgroups with increased risk of ASCVD events 1-year after-COPD hospitalization. Further research is needed to characterize the COPD exacerbation populations at highest ASCVD hospitalization risk.

ABSTRACT

AIM: There are limited data to evaluate hospitalization for heart failure (hHF) in non-Hispanic Black (hereafter Black) or non-Hispanic White (hereafter White) individuals without previous hHF. Our goal was to evaluate the risk of hHF among Black versus White patients with type 2 diabetes (T2DM) who were initially prescribed empagliflozin using real-world data. METHODS: This multicentre retrospective cohort study included participants aged ≥18 years who had T2DM, were either Black or White, had no previous hHF, and were prescribed empagliflozin between August 2014 and December 2019. Our primary outcome was time to first hHF after the initial prescription of empagliflozin. A propensity-score (PS)-weighted analysis was performed to balance characteristics by race. The inverse probability treatment weighting method based on PS was used to make treatment comparisons. To compare Black with White, a PS-weighted Cox's cause-specific hazards model was used. RESULTS: In total, 8789 participants were eligible for inclusion (Black = 3216 vs. White = 5573). The Black cohort was significantly younger, had a higher proportion of females, and had a higher prevalence of chronic kidney disease, hypertension and diabetic retinopathy, while the White cohort had a higher prevalence of coronary artery disease. After adjustment for confounding factors such as age, gender, coronary artery disease, hypertension and diabetic retinopathy, the hazard ratio for first-time hHF was not significantly different between the two racial groups [hazard ratio (95% confidence interval) = 1.09 (0.84-1.42), p = .52]. CONCLUSION: This study showed no significant difference in incident hHF among Black versus White individuals with T2DM following a prescription for empagliflozin.

ABSTRACT

Background: Symptoms, severity, and acuteness of peripheral artery disease (PAD) are major determinants of severe limb symptoms, subsequent risk of cardiovascular events, and mortality. Lower-extremity revascularization (LER) is a key option to relieve symptoms and to prevent limb loss in symptomatic patients with PAD. This study aimed to quantify the burden of disease among patients with PAD-LER in England. Methods: A retrospective population-based study of linked primary and secondary care electronic health records, included 13,869 adult patients (aged ⩾ 18 years) with PAD-LER from 2003 to 2018. The incidence of first ever PAD-LER was estimated both overall and by type of procedure (endovascular/surgical). Health resource utilization associated with PAD-related complications and treatment patterns were assessed. Results: A high annual incidence of lower-limb revascularization (41.2 per 1000 person years) and a nearly double incidence of endovascular first revascularization compared with open surgery were observed. More than 70% of patients with PAD-LER had a history of hyperlipidemia and hypertension and roughly one-third were diabetic and had a history of coronary artery disease. Cardiovascular mortality accounted for one-third (34.1 per 1000 person years) of all-cause mortality. Over 93% of patients were hospitalized for any reason and the commonest reasons for hospitalization were cardiovascular diseases and PAD with about one-third hospitalized for revascularization reoccurrence. Conclusion: There is a significant burden of PAD-LER to the individual and society with ongoing healthcare resource utilization, treatment, and increasing mortality.

ABSTRACT

BACKGROUND: The presence of a contralateral carotid occlusion (CCO) is an established high-risk feature for patients undergoing carotid endarterectomy (CEA) and is traditionally an indication for carotid artery stenting (CAS). Recent observational data have called into question whether CCO remains a high-risk feature for CEA. OBJECTIVES: The purpose of this study was to determine the clinical impact of CCO among patients undergoing CEA and CAS in a contemporary nationwide registry. METHODS: All patients undergoing CEA or CAS from 2007 to 2019 in the NCDR CARE (National Cardiovascular Data Registry Carotid Artery Revascularization and Endarterectomy) and PVI (Peripheral Vascular Intervention) registries were included. The primary exposure was the presence of CCO. The outcome was a composite of in-hospital death, stroke, and myocardial infarction. Multivariable logistic regression and inverse-probability of treatment weighting were used to compare outcomes. RESULTS: Among 58,423 patients who underwent carotid revascularization, 4,624 (7.9%) had a CCO. Of those, 68.9% (n = 3,185) underwent CAS and 31.1% (n = 1,439) underwent CEA. The average age of patients with CCO was 69.5 ± 9.7 years, 32.6% were women, 92.8% were Caucasian, 51.7% had a prior transient ischemic attack or stroke, and 45.4% presented with symptomatic disease. Over the study period, there was a 41.7% decrease in the prevalence of CCO among patients who underwent carotid revascularization (p < 0.001), but CAS remained the primary revascularization strategy. Unadjusted composite outcome rates were lower in patients with CCO after CAS (2.1%) than CEA (3.6%). Following adjustment, CCO was associated with a 71% increase in the odds of an adverse outcome after CEA (95% confidence interval: 1.27 to 2.30; p < 0.001) compared with no increase after CAS (adjusted odds ratio: 0.94; 95% confidence interval: 0.72 to 1.22; p = 0.64). CONCLUSIONS: CCO remains an important predictor of increased risk among patients undergoing CEA, but not CAS.

ABSTRACT

Cardioprotective medications and risk-factor modification are the hallmarks of treatment for all patients with peripheral artery disease (PAD). If symptoms are life-limiting and/or do not respond to conservative treatment, endovascular or surgical revascularization can be considered especially for patients with critical limb ischemia or acute limb ischemia. The rates of peripheral vascular intervention (PVI) have risen dramatically over the past few decades and much of this care have shifted from inpatient hospital settings to outpatient settings and office-based clinics. While PVI rates have surged and technology advancements have dramatically changed the face of PVI, the data behind optimal antithrombotic therapy following PVI is scant. Currently in the USA, most patients are treated with indefinite aspirin therapy and a variable duration of clopidogrel (or other P2Y12 inhibitor)-typically 1 month, 3 months, or indefinite therapy. More observational analyses and randomized clinical trials evaluating clinically relevant outcomes such as cardiovascular morbidity/mortality and the risk of bleeding are needed to guide the optimal role and duration of antithrombotic therapy post-PVI.
