Background: There are limited data on substance use (SU) and cardiovascular disease (CVD)–related mortality trends in the United States. We aimed to evaluate SU+CVD–related deaths in the United States using the Centers for Disease Control and Prevention Wide‐Ranging, Online Data for Epidemiologic Research database. Methods and Results: The Multiple Cause‐of‐Death Public Use record death certificates were used to identify deaths related to both SU and CVD. Crude, age‐adjusted mortality rates, annual percent change, and average annual percent changes with a 95% CI were analyzed. Between 1999 and 2019, there were 636 572 SU+CVD‐related deaths (75.6% men, 70.6% non‐Hispanic White individuals, 65% related to alcohol). Age‐adjusted mortality rates per 100 000 population were pronounced in men (22.5 [95% CI, 22.6–22.6]), American Indian or Alaska Native individuals (37.7 [95% CI, 37.0–38.4]), nonmetropolitan/rural areas (15.2 [95% CI, 15.1–15.3]), and alcohol‐related death (9.09 [95% CI, 9.07 to 9.12]). The overall SU+CVD‐related age‐adjusted mortality rates increased from 9.9 (95% CI, 9.8–10.1) in 1999 to 21.4 (95% CI, 21.2–21.6) in 2019 with an average annual percent change of 4.0 (95% CI, 3.7–4.3). Increases in SU+CVD‐related average annual percent change were noted across all subgroups and were pronounced among women (4.8% [95% CI, 4.5–5.1]), American Indian or Alaska Native individuals, younger individuals, nonmetropolitan areas, and cannabis and psychostimulant users. Conclusions: There was a prominent increase in SU+CVD‐related mortality in the United States between 1999 and 2019. Women, non‐Hispanic American Indian or Alaska Native individuals, younger individuals, nonmetropolitan area residents, and users of cannabis and psychostimulants had pronounced increases in SU+CVD mortality.

Objective: Recent studies have shown that atrial fibrillation (AF) is more prevalent in patients with retinal vessel occlusion and may be associated with both central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO). However, there is no systematic review and meta-analysis to confirm this finding. Methods: We searched the databases of MEDLINE and EMBASE from inception to January 2019. Included studies were published cohort, case-control or cross-sectional studies, and randomized control trials reporting the prevalence of AF in patients with CRAO or CRVO. Data from each study were combined using the random-effects model. Results: Eleven studies were included in our meta-analysis, involving a total population of 12,305 subjects with retinal vessel occlusion. The prevalence of AF ranged from 4.1% to 21.4% (pooled prevalence=11.5%, 95% CI: 7.0-16.1, I²=96.3 %). Five studies reported a control group of patients without retinal vessel occlusion. We found that AF is significantly associated with retinal vessel occlusion (pooled OR=2.24, 95% CI:2.07-2.43, I²=0.0%) Conclusion: Our study showed that AF is significantly associated with retinal vessel occlusion. Further studies are needed to fully elucidate the exact mechanism linking AF with CRAO and CRVO.

Recent systematic review and meta-analysis showed that the prevalence of cognitive impairment was significantly increased in patients with heart failure (HF) when compared to the general population. However, the effect of cognitive impairment on cardiovascular outcome in this population is still unclear. We performed a systematic review and meta-analysis to assess whether cognitive impairment associated with worse outcome in patients with HF. We comprehensively searched the databases of MEDLINE and EMBASE from inception to October 2018. Included studies were published cohort (prospective or retrospective) or randomized control trials that evaluate the effect of cognitive impairment mortality in HF patients. Data from each study were combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate pooled hazard ratios (HR) and 95% confidence intervals (CI). Eight studies were included in the analysis involving 3318 participants (951 participants had cognitive impairment). In a random-effects model, our analysis demonstrated that cognitive impairment significantly increased the risk of mortality in HF patients (pooled HR = 1.64, 95% CI = 1.42-1.88, I2 = 0.0%, p < 0.001). Our systematic review and meta-analysis showed that the presence of cognitive impairment is strongly associated with an increased mortality risk in the HF population. Further research is needed to explore the pathophysiology of this association.

Heart failure (HF) is one of the world leading causes of hospitalization and rehospitalization. Cognitive impairment has been identified as a risk factor for rehospitalization in patients with heart failure. However, previous studies reported mixed results. Therefore, we conducted a systematic review and meta-analysis to assess the association between cognitive impairment and 30-day rehospitalization in patients with HF. We performed a comprehensive literature search through July 2018 in the databases of MEDLINE and EMBASE. Included studies were cohort studies, case-control studies, cross-sectional studies or randomized controlled trials that compared the risk of 30-day rehospitalization in HF patients with cognitive impairment and those without. We calculated pooled relative risk (RR) with 95% confidence intervals (CI) and I2 statistic using the random-effects model. Five studies with a total of 2,342 participants (1,004 participants had cognitive impairment) were included for meta-analysis. In random-effect model, cognitive impairment significantly increased the risk of 30-day rehospitalization in HF participants (pooled RR=1.63, 95%CI: 1.19-2.24], I2=64.2%, p=0.002). Subgroup analysis was performed on the studies that excluded patients with dementia. The results also showed that cognitive impairment significantly increased the risk of 30-day rehospitalization in participants with HF (pooled RR=1.29, 95%CI: 1.05-1.59, I2=0.0%, p=0.016), which was consistent with our overall analysis. Our meta-analysis demonstrated that the presence of cognitive impairment is associated with 30-day rehospitalization in patients with HF.
