Background

Atrial fibrillation (AF) is associated with adverse outcomes in terms of survival and morbidity. Peripheral artery disease (PAD) and AF share several common risk factors and often coexist. Whether AF has a prognostic role in patients with PAD has not been extensively studied.

Hypothesis

AF is associated with major adverse cardiac events (MACE) and mortality in symptomatic PAD patients.

Methods

Using MEDLINE and Scopus, we searched for studies published before December 2016 that evaluated cardiovascular outcomes based on the presence/absence of AF in a prospective manner with a follow‐up period of ≥12 months. The outcomes were reported using a random‐effects model, and heterogeneity was assessed using the I 2 statistic. Sensitivity analyses were performed to test the contribution of each study to the overall results.

Results

Six prospective studies (Newcastle‐Ottawa score range, 7–9) with 14 656 patients were included in the final analysis (age range, 66–70 years; median follow‐up, 1.4 years). Our pooled analysis found a significant association between AF and mortality (odds ratio: 2.52, 95% confidence interval: 1.91‐3.34, I 2 = 32.6%), without evidence of publication bias (P = 0.63). Meta‐analysis showed a significant impact of AF on MACE (odds ratio: 2.54, 95% confidence interval: 1.78‐3.63, I 2 = 74.3%), without detected publication bias (P = 0.08).

Conclusions

AF is associated with increased risk of mortality and MACE in symptomatic PAD.

Objective. We sought to develop a method to adjust for case mix diversity and allow comparison of adverse outcome rates among practitioners in pediatric and congenital cardiac catheterization. Patients and Methods. A single institutional database that captured demographic and procedural data was used to identify patient and procedural characteristics associated with adverse events (AE) and any high severity event classified as preventable or possibly preventable (P/PP). Diagnostic and procedural risk groups were created and indicators of hemodynamic vulnerability were defined. Expected event rates by the practitioners adjusting for case mix were calculated. Standardized adverse event ratios (SAER), defined as the observed rate divided by the expected rate for each practitioner were calculated with 95% confidence intervals. Results. The database included 1727 hemodynamic (30%) and interventional (70%) cases performed by seven practitioners in 18 months. During 147 cases, at least one P/PP AE occurred; among the seven practitioners observed, event rates ranged from 3.2 to 14.2%. In multivariable analysis, risk factors for all P/PP events included highest procedure risk group (odds ratio [OR] 2.1 for group 2, and 2.8 for group 3, relative to group 1, P = .001 and P < .001, respectively) and weight less than 4 kg (OR 2.8, P < .001). High severity P/PP events occurred in 67 cases with rates ranging from 2.0 to 6.6% by the practitioners. For these events, risk factors included: highest procedure risk group (OR 4.5 for group 2, and 4.9 for group 3, both P < .001) and an indicator of hemodynamic vulnerability (OR 1.8, P = .026). For the seven practitioners, the SAER ranged from 0.41 to 1.32 for any P/PP AE and from 0.69 to 1.44 for P/PP high severity events. In this cohort, we did not identify any statistically significant performance differences. Conclusion. Despite wide variations in case mix complexity in pediatric and congenital cardiac catheterization, this study demonstrates a method for risk adjustment which allows equitable comparisons among practitioners at a single institution.  相似文献

Background

Patient's knowledge about heart failure (HF) contributes to successful HF self-care, but less is known about shared patient-caregiver knowledge.

Objectives

The purpose of this analysis was to: 1) identify configurations of shared HF knowledge in patient-caregiver dyads; 2) characterize dyads within each configuration by comparing sociodemographic factors, HF characteristics, and psychosocial factors; and 3) quantify the relationship between configurations and patient self-care adherence to managing dietary sodium and HF medications.

Methods

This was a secondary analysis of cross-sectional data (N = 114 dyads, 53% spousal). Patient and caregiver HF knowledge was measured with the Atlanta Heart Failure Knowledge Test. Patient dietary sodium intake was measured by 3-day food record and 24 h urine sodium. Medication adherence was measured by Medication Events Monitoring System caps. Patient HF-related quality of life was measured by the Minnesota Heart Failure Questionnaire; caregiver health-related quality of life was measured by the Short Form-12 Physical Component Summary. Patient and caregiver depression were measured with the Beck Depression Inventory-II. Patient and caregiver perceptions of caregiver-provided autonomy support to succeed in heart failure self-care were measured by the Family Care Climate Questionnaire. Multilevel and latent class modeling were used to identify dyadic knowledge configurations. T-tests and chi-square tests were used to characterize differences in sociodemographic, clinical, and psychosocial characteristics by configuration. Logistic/linear regression were used to quantify relationships between configurations and patient dietary sodium and medication adherence.

Results

Two dyadic knowledge configurations were identified: “Knowledgeable Together” (higher dyad knowledge, less incongruence; N = 85, 75%) and “Knowledge Gap” (lower dyad knowledge, greater incongruence; N = 29, 25%). Dyads were more likely to be in the “Knowledgeable Together” group if they were White and more highly educated, if the patient had a higher ejection fraction, fewer depressive symptoms, and better autonomy support, and if the caregiver had better quality of life. In unadjusted comparisons, patients in the “Knowledge Gap” group were less likely to adhere to HF medication and diet. In adjusted models, significance was retained for dietary sodium only.

Conclusions

Dyads with higher shared HF knowledge are likely more successful with select self-care adherence behaviors.  相似文献

Background and aimsTriglyceride-Glucose (TyG) index is an accurate biomarker of insulin resistance, which is potentially associated with adverse cardiovascular events. We aimed to assess the dose–response relationship between Triglyceride-Glucose (TyG) Index and Major Adverse Cardiovascular Events (MACE) in patients with Acute Coronary Syndrome (ACS).Methods and resultsA systematic literature search was performed using PubMed, Scopus, and Embase for records published from the inception up until 7 February 2021. Studies that fulfilled all of these criteria were included: 1) prospective or retrospective observational studies reporting patients with ACS and 2) assessing the impact of TyG index on MACE with at least three quantitative classifications. The outcome of interest is MACE across the TyG index intervals. MACE was a composite of all-cause mortality, myocardial infarction, unstable angina pectoris, target vessel revascularization, cerebrovascular accidents, and heart failure. The effect estimates were reported as relative risks (RRs). There are 13,684 subjects from 4 studies included in this meta-analysis. This meta-analysis showed that the highest category of TyG index was associated with twofold MACE (RR 2.09 [1.59, 2.76], p < 0.001; I2: 68.4%, p = 0.02) compared to the lowest category in patients with ACS. Dose–response meta-analysis showed that the relationship between TyG index and MACE was non-linear (p < 0.001), with statistical significance reached around TyG index 8.9 and increased non-linearly. The dose–response curve became significantly steeper after TyG index of 9.1–9.2.ConclusionTyG index was associated with MACE in patients with ACS in a non-linear fashion.ProsperoCRD42021235765.  相似文献

Corresponding to the uncontrolled diabetes pandemic, significant effort has been invested in developing new therapeutic options. Nevertheless, all medicines have possible adverse effects. Recently, a trend of 'scrutinizing' novel hypoglycaemic drug side effects based on scant scientific data has emerged. With recent publications highlighting possible dangers of rosiglitazone, insulin glargine, sitagliptin, exenatide and, most recently, pioglitazone, it seems that all means are valid and that every database is suitable, even if specifically defined as inadequate for the purpose of data analysis. The use of such data may lead authors to draw erroneous conclusions that may be granted unwarranted impact upon publication in leading scientific journals and eventually lead patients and misinformed physicians to wrongly change beneficial medication regimes. Adherence to strict scientific methodology, ongoing large clinical trials and creating adjudicated patient databases may facilitate early recognition of adverse effects while avoiding disruptive false alarms.  相似文献
