Cardiovascular Risk Factors: It's Time to Focus on Variability!

Barnett, Mallory P; Bangalore, Sripal
Atherosclerotic heart disease remains a leading cause of morbidity and mortality worldwide. While extensive research supports cardiovascular risk factor reduction in the form of achieving evidence-based blood pressure, lipid, glucose, and body weight targets as a means to improve cardiovascular outcomes, residual risk remains. Emerging data have demonstrated that the intraindividual variability of these risk factor targets potentially contribute to this residual risk. It may therefore be time to define risk factor by not only its magnitude and duration as done traditionally, but perhaps also by the variability of that particular risk factor over time.

Relationship between neutrophil-lymphocyte ratio and severity of lower extremity peripheral artery disease

BACKGROUND: The aim of this study was to determine the association between neutrophil-lymphocyte ratio (NLR) and severity of lower extremity peripheral artery disease (PAD). METHODS: A retrospective chart review identified 928 patients referred for peripheral angiography. NLR was assessed from routine pre-procedural hemograms with automated differentials and available in 733 patients. Outcomes of interest were extent of disease on peripheral angiography and target vessel revascularization. Median follow-up was 10.4months. Odds ratio (OR) [95% confidence intervals] was assessed using a logistic regression model. RESULTS: There was a significant association between elevated NLR and presence of severe multi-level PAD versus isolated suprapopliteal or isolated infrapopliteal disease (OR 1.11 [1.03-1.19], p=0.007). This association remained significant even after adjustment for age (OR 1.09 [1.01-1.17], p=0.02); age, sex, race, and body mass index (OR 1.08 [1.00-1.16], p=0.046); and age, sex, race, body mass index, hypertension, diabetes mellitus, coronary artery disease, and creatinine (OR 1.07 [1.00-1.15], p=0.049). After additional adjustment for clinical presentation, there was a trend towards association between NLR and severe multi-level PAD (OR 1.07 [1.00-1.15], p=0.056), likely limited by sample size. In patients who underwent endovascular intervention (n=523), there was no significant difference in rate of target vessel revascularization across tertiles of NLR (1st tertile 14.8%, 2nd tertile 14.1%, 3rd tertile 20.1%; p=0.32). CONCLUSION: In a contemporary cohort of patients undergoing peripheral angiography with possible endovascular intervention, elevated NLR was independently associated with severe multi-level PAD. Larger studies evaluating the association between this inexpensive biomarker and clinical outcomes are warranted.

Socioeconomic determinants associated with willingness to participate in medical research among a diverse population

Svensson, Katherine; Ramirez, Olivia F; Peres, Frederico; Barnett, Mallory; Claudio, Luz
INTRODUCTION: Although it is federally-mandated that racial/ethnic minorities be included in research studies, recruiting diverse populations remains a challenge. This is particularly difficult when research involves children. The purpose of this study was to assess attitudes and beliefs toward medical research among a racially and socioeconomically diverse population of parents of school children. METHODS: A cross-sectional parent-report survey was conducted in New York City public elementary schools using stratified random selection to obtain a diverse population. Fear of medical research and likelihood to participate in medical research were assessed using a validated questionnaire. Differences in fear/likelihood to participate in research across race/ethnicity and socioeconomic characteristics were evaluated. RESULTS: In general, parents were afraid of their child "being treated as a guinea pig", but were willing to allow their child to participate in research if asked by their own doctor. Factors associated with a lower score on fear toward research were; primary language other than English (OR=0.59), access to an interpreter (OR=0.73) and access to medical service within a day (OR=0.51). Latinos had the highest fear score (OR=1.87) compared to Whites. Asians were the ethnic group most likely to participate in research (OR=1.71). Low education level (OR=2.18) and public health insurance (OR=1.37) were associated with a higher score for likelihood of allowing one's child to participate in medical research. CONCLUSION: Minority parents reported more fear of allowing their children to participate in medical research, but were as likely to consent their children's participation, especially if asked by their own physician.
