Acute Coronary Syndrome Revascularization Strategies With Multivessel Coronary Artery Disease. Am J Cardiol 2024; 220:33-38. [PMID: 38582315 DOI: 10.1016/j.amjcard.2024.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 03/03/2024] [Accepted: 04/02/2024] [Indexed: 04/08/2024]
Abstract
In acute coronary syndromes (ACS), revascularization is the standard of care. However, trials comparing contemporary coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are limited. Optimal revascularization in patients with multivessel coronary artery disease (MV-CAD) presenting with ACS is unclear. This is a multicentered, retrospective observational study from a large hospital system in the United States. We abstracted data in patients with MV-CAD and ACS from 2018 to 2022 who underwent revascularization with PCI, CABG, or medical management (MM). We evaluated multivariate statistics comparing categorical variables and outcomes, including all-cause mortality and myocardial infarction (MI) at 1 year. All logistic and Cox proportional-hazard models were balanced using inverse probability treatment weights accounting for age and gender. There were 295 patients with CABG (median age 66 years [interquartile range 59.7 to 73.1]; 73% male), 1,559 patients with PCI (median age 68.3 years [interquartile range 60 to 76.6]; 69.1% male], and 307 patients with MM (median age 70 years [60.9 to 77.1] 74% male]. Patients revascularized with PCI had greater all-cause mortality at 1 year (14.1% vs 5.1%; hazard ratio 2.4, confidence interval [1.5 to 3.8], p <0.001) and similar mortality to MM (13.4%). CABG also showed a reduced 1-year MI rate compared with PCI (1.7% vs 3.9%; hazard ratio 0.36, confidence interval 0.21 to 0.61, p ≤0.001), with a similar 1-year rate of MI to MM (3.9%). In conclusion, CABG is associated with lower mortality than are PCI and MM, and repeat ACS events at 1 year in patients with ACS and MV-CAD.

Patient characteristics associated with acute kidney injury following coronary angiography. Proc AMIA Symp 2024; 37:382-387. [PMID: 38628321 PMCID: PMC11018084 DOI: 10.1080/08998280.2024.2301903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 12/27/2023] [Indexed: 04/19/2024] Open
Abstract
Objective The objective of this study was to identify patient characteristics associated with acute kidney injury (AKI) post-coronary angiography with or without percutaneous coronary intervention. Methods This retrospective, single-center study analyzed 350 patients from October 1, 2017 to September 30, 2018. The primary endpoint was AKI, defined as a rise in creatinine >0.3 mg/dL within 48 hours of coronary angiography. Results AKI occurred in 41 of 350 patients (8.8%). Patients experiencing AKI had a higher incidence of hypertension (100%; P = 0.005), hyperlipidemia (98%; P = 0.001), diabetes mellitus (68%; P = 0.0005), and heart failure (37%; P = 0.0057). AKI occurred in 30 of 185 (16%) and 11 of 165 (6.7%) patients undergoing femoral and radial access, respectively. AKI incidence was not significantly affected by contrast dose (99 ± 9 vs 93 ± 3 mL; P = 0.52), fluoroscopy time (10.3 min [IQR 6.3, 17.7] vs 8.5 min [IQR 4.5, 13.9]; P = 0.2), or preprocedural computed tomography with contrast (P = 0.66). Multivariable regression showed significantly higher AKI among patients with peripheral artery disease (odds ratio [OR] = 12.4; 95% confidence interval [CI] 3.4-33.6; P = 0.0001), multivessel coronary artery disease (OR = 11.9; 95% CI 2.3-61.1; P = 0.003), and initial creatinine >1.5 mg/dL (OR = 4.4; 95% CI 1.4-13.6; P = 0.01). Conclusion Peripheral artery disease, multivessel disease, and creatinine >1.5 mg/dL were associated with a higher risk of AKI in patients undergoing coronary angiography in this single-center retrospective cohort.

Abstract
Angina with nonobstructive coronary arteries (ANOCA) is increasingly recognized and may affect nearly one-half of patients undergoing invasive coronary angiography for suspected ischemic heart disease. This working diagnosis encompasses coronary microvascular dysfunction, microvascular and epicardial spasm, myocardial bridging, and other occult coronary abnormalities. Patients with ANOCA often face a high burden of symptoms and may experience repeated presentations to multiple medical providers before receiving a diagnosis. Given the challenges of establishing a diagnosis, patients with ANOCA frequently experience invalidation and recidivism, possibly leading to anxiety and depression. Advances in scientific knowledge and diagnostic testing now allow for routine evaluation of ANOCA noninvasively and in the cardiac catheterization laboratory with coronary function testing (CFT). CFT includes diagnostic coronary angiography, assessment of coronary flow reserve and microcirculatory resistance, provocative testing for endothelial dysfunction and coronary vasospasm, and intravascular imaging for identification of myocardial bridging, with hemodynamic assessment as needed.

Abstract
Centers specializing in coronary function testing are critical to ensure a systematic approach to the diagnosis and treatment of angina with nonobstructive coronary arteries (ANOCA). Management leveraging lifestyle, pharmacology, and device-based therapeutic options for ANOCA can improve angina burden and quality of life in affected patients. Multidisciplinary care teams that can tailor and titrate therapies based on individual patient needs are critical to the success of comprehensive programs. As coronary function testing for ANOCA is more widely adopted, collaborative research initiatives will be fundamental to improve ANOCA care. These efforts will require standardized symptom assessments and data collection, which will propel future large-scale clinical trials.

Abstract
BACKGROUND Many COVID-19 studies are constructed to report hospitalization outcomes, with few large multi-center population-based reports on the time course of intra-hospitalization characteristics, including daily oxygenation support requirements. Comprehensive epidemiologic profiles of oxygenation methods used by day and by week during hospitalization across all severities are important to illustrate the clinical and economic burden of COVID-19 hospitalizations. METHODS This was a retrospective, multi-center observational cohort study of 15,361 consecutive hospitalizations of patients with COVID-19 at 25 adult acute care hospitals in Texas participating in the Society of Critical Care Medicine Discovery Viral Respiratory Illness Universal Study COVID-19 registry. RESULTS At initial hospitalization, the majority required nasal cannula (44.0%), with an increasing proportion of invasive mechanical ventilation in the first week and particularly the weeks to follow. After 4 weeks of acute illness, 69.9% of adults hospitalized with COVID-19 required intermediate (eg, high-flow nasal cannula, noninvasive ventilation) or advanced respiratory support (ie, invasive mechanical ventilation), with similar proportions that extended to hospitalizations that lasted ≥ 6 weeks. CONCLUSIONS Data representation of intra-hospital processes of care drawn from hospitals with varied size, teaching and trauma designations is important to presenting a balanced perspective of care delivery mechanisms employed, such as daily oxygen method utilization.

Abstract
BACKGROUND Thrombosis and inflammation may contribute to the risk of death and complications among patients with coronavirus disease 2019 (Covid-19). We hypothesized that therapeutic-dose anticoagulation may improve outcomes in noncritically ill patients who are hospitalized with Covid-19. METHODS In this open-label, adaptive, multiplatform, controlled trial, we randomly assigned patients who were hospitalized with Covid-19 and who were not critically ill (which was defined as an absence of critical care-level organ support at enrollment) to receive pragmatically defined regimens of either therapeutic-dose anticoagulation with heparin or usual-care pharmacologic thromboprophylaxis. The primary outcome was organ support-free days, evaluated on an ordinal scale that combined in-hospital death (assigned a value of -1) and the number of days free of cardiovascular or respiratory organ support up to day 21 among patients who survived to hospital discharge. This outcome was evaluated with the use of a Bayesian statistical model for all patients and according to the baseline d-dimer level. RESULTS The trial was stopped when prespecified criteria for the superiority of therapeutic-dose anticoagulation were met. Among 2219 patients in the final analysis, the probability that therapeutic-dose anticoagulation increased organ support-free days as compared with usual-care thromboprophylaxis was 98.6% (adjusted odds ratio, 1.27; 95% credible interval, 1.03 to 1.58). The adjusted absolute between-group difference in survival until hospital discharge without organ support favoring therapeutic-dose anticoagulation was 4.0 percentage points (95% credible interval, 0.5 to 7.2). The final probability of the superiority of therapeutic-dose anticoagulation over usual-care thromboprophylaxis was 97.3% in the high d-dimer cohort, 92.9% in the low d-dimer cohort, and 97.3% in the unknown d-dimer cohort. Major bleeding occurred in 1.9% of the patients receiving therapeutic-dose anticoagulation and in 0.9% of those receiving thromboprophylaxis. CONCLUSIONS In noncritically ill patients with Covid-19, an initial strategy of therapeutic-dose anticoagulation with heparin increased the probability of survival to hospital discharge with reduced use of cardiovascular or respiratory organ support as compared with usual-care thromboprophylaxis.

Abstract
BACKGROUND Thrombosis and inflammation may contribute to morbidity and mortality among patients with coronavirus disease 2019 (Covid-19). We hypothesized that therapeutic-dose anticoagulation would improve outcomes in critically ill patients with Covid-19. METHODS In an open-label, adaptive, multiplatform, randomized clinical trial, critically ill patients with severe Covid-19 were randomly assigned to a pragmatically defined regimen of either therapeutic-dose anticoagulation with heparin or pharmacologic thromboprophylaxis in accordance with local usual care. The primary outcome was organ support-free days, evaluated on an ordinal scale that combined in-hospital death (assigned a value of -1) and the number of days free of cardiovascular or respiratory organ support up to day 21 among patients who survived to hospital discharge. RESULTS The trial was stopped when the prespecified criterion for futility was met for therapeutic-dose anticoagulation. Data on the primary outcome were available for 1098 patients (534 assigned to therapeutic-dose anticoagulation and 564 assigned to usual-care thromboprophylaxis). The median value for organ support-free days was 1 (interquartile range, -1 to 16) among the patients assigned to therapeutic-dose anticoagulation and was 4 (interquartile range, -1 to 16) among the patients assigned to usual-care thromboprophylaxis (adjusted proportional odds ratio, 0.83; 95% credible interval, 0.67 to 1.03; posterior probability of futility [defined as an odds ratio <1.2], 99.9%). The percentage of patients who survived to hospital discharge was similar in the two groups (62.7% and 64.5%, respectively; adjusted odds ratio, 0.84; 95% credible interval, 0.64 to 1.11). Major bleeding occurred in 3.8% of the patients assigned to therapeutic-dose anticoagulation and in 2.3% of those assigned to usual-care pharmacologic thromboprophylaxis. CONCLUSIONS In critically ill patients with Covid-19, an initial strategy of therapeutic-dose anticoagulation with heparin did not result in a greater probability of survival to hospital discharge or a greater number of days free of cardiovascular or respiratory organ support than did usual-care pharmacologic thromboprophylaxis.

Abstract
OBJECTIVE Troponin values above the threshold established to diagnose acute myocardial infarction (AMI; >99th percentile) are commonly detected in patients with diagnoses other than AMI. The objective of this study was to compare inpatient mortality and 30-day readmission rate in patients with troponin I (TnI) above and below the 99th percentile in those with type 1 AMI and type 2 myocardial injury. METHODS Between January 1, 2016 and December 31, 2016, there were 56,895 inpatient hospitalizations; of these 14,326 (25.2%) patients received troponin testing. We evaluated mortality and readmissions in the entire cohort based on the primary discharge International Classification of Diseases, Tenth Edition (ICD-10) diagnosis and grouped into type 1 AMI versus other diagnoses comprising the type 2 AMI group (including ICD-10 codes for congestive heart failure, sepsis, and other). Among those with TnI drawn, we evaluated in-hospital mortality and 30-day readmissions based on troponin values > 99th percentile (≥ 0.1 ng/ml). RESULTS Among the entire cohort, the inpatient mortality rate was significantly higher in those with TnI testing (5.0%, 95% CI 4.6%-5.3%) compared to those without testing (0.7%, 95% CI 0.6%-0.7%, P < 0.01). In the tested cohort 3,743 (26%) patients had troponin levels above the 99th percentile (> 0.1 ng/ml), and 10,583 (74%) had troponin levels below the 99th percentile (≤ 0.1 ng/ml). Comparing type 2 AMI with type 1 AMI and troponin testing, TnI values ≥ 0.1 ng/ml were associated with higher inpatient mortality (11.6% vs. 3.9%) and 30-day readmission rates (16.9% vs. 10.7%). CONCLUSIONS A higher inpatient mortality and 30-day readmission rates were found in patients with type 2 AMI compared to type 1 AMI group.

Abstract
OBJECTIVES The aim of this study was to describe management of recurrent pulmonary vein stenosis (PVS) and determine if stenting is superior to balloon angioplasty (BA) in preventing subsequent restenosis. BACKGROUND PVS is a serious complication of atrial fibrillation ablation. BA and stenting are effective therapies; however, restenosis frequently occurs. Here we report management of recurrent stenosis. METHODS This was a prospective observational study performed from 2000 to 2014. RESULTS One hundred and thirteen patients with severe PVS underwent intervention in 88 veins treated with BA and 81 treated with stenting. Forty-two patients experienced restenosis. Restenosis was more common in veins treated with BA (RRR 53% [95% CI 32-70%, p = .008]). A second intervention was performed in 41 patients. In the 34 vessels treated with initial BA, 24 were treated for restenosis with a stent and 10 were treated with a second BA. The recurrence rate was 46% in those treated with BA followed by stenting and 50% in those treated with two BA procedures. In the 22 veins treated with initial stenting, 9 were treated with another stent and 13 were treated with BA. The recurrence rate was 44% in those treated with a second stent and 46% for those treated with a stent followed by BA. The risk of a third stenosis was the same among all groups (Analysis of variance [ANOVA] p = .99). Limited sample size precluded analysis of outcome by stent size. CONCLUSIONS Restenosis occurred in 44% of patients overall. Management is challenging; stenting does not appear to be superior to BA.

Abstract
Background Previous data have validated the benefit of digital health interventions (DHIs) on weight loss in patients following acute coronary syndrome entering cardiac rehabilitation (CR). Objective The primary purpose of this study was to test the hypothesis that increased DHI use, as measured by individual log-ins, is associated with improved weight loss. Secondary analyses evaluated the association between log-ins and activity within the platform and exercise, dietary, and medication adherence. Methods We obtained DHI data including active days, total log-ins, tasks completed, educational modules reviewed, medication adherence, and nonmonetary incentive points earned in patients undergoing standard CR following acute coronary syndrome. Linear regression followed by multivariable models were used to evaluate associations between DHI log-ins and weight loss or dietary adherence. Results Participants (n=61) were 79% male (48/61) with mean age of 61.0 (SD 9.7) years. We found a significant positive association of total log-ins during CR with weight loss (r2=.10, P=.03). Educational modules viewed (r2=.11, P=.009) and tasks completed (r2=.10, P=.01) were positively significantly associated with weight loss, yet total log-ins were not significantly associated with differences in dietary adherence (r2=.05, P=.12) or improvements in minutes of exercise per week (r2=.03, P=.36). Conclusions These data extend our previous findings and demonstrate increased DHI log-ins portend improved weight loss in patients undergoing CR after acute coronary syndrome. DHI adherence can potentially be monitored and used as a tool to selectively encourage patients to adhere to secondary prevention lifestyle modifications.

Abstract
BACKGROUND The role of dobutamine stress echocardiography (DSE) in the risk stratification of patients undergoing noncardiac surgery in the current era is unclear. The aim of this study was to evaluate the yield of DSE and the additive role of DSE to clinical criteria for preoperative risk stratification of patients undergoing noncardiac surgery. METHODS The study included 4,494 patients undergoing DSE ≤90 days before noncardiac surgery. The primary outcome was a composite of postoperative myocardial infarction, cardiac arrest, and all-cause mortality ≤30 days after noncardiac surgery. RESULTS The overall 30-day postoperative cardiac event rate was 2.3%. The mortality rate was 0.9% overall and 0.7% and 1.3% after normal and abnormal results on DSE, respectively. Among clinical variables, the modified Revised Cardiac Risk Index score demonstrated the strongest association with postoperative risk (P < .001). Patients with Revised Cardiac Risk Index scores of ≥3 had an event rate of 7.5%. The event rates for patients with wall motion score index ≥1.7 at baseline, left ventricular ejection fractions <40% at peak stress, or ischemic thresholds <70% of age-predicted maximal heart rate were 7.1%, 8.6%, and 7.9%, respectively. After adjusting for clinical variables, the overall result of DSE (P < .001), baseline and peak-stress wall motion score index (P < .001 and P = .014, respectively), peak-stress left ventricular ejection fraction (P < .001), and the number of ischemic segments (P = .027) were all associated with postoperative cardiac events. Incremental multivariate analysis demonstrated that an overall abnormal result on DSE, added to clinical variables, was associated with an increased risk for postoperative cardiac events (odds ratio, 2.07; 95% CI, 1.35-3.17; P < .001). CONCLUSIONS Baseline and peak-stress findings on preoperative DSE add to the prognostic utility of clinical variables for stratifying cardiac risk after noncardiac surgery.

Abstract
Importance Online search for symptoms is common and may be useful in early identification of patients experiencing coronary heart disease (CHD) and in epidemiologically studying the disease. Objective To investigate the correlation of online symptom search for chest pain with disease prevalence of CHD. Design, Setting, and Participants This retrospective study used Google Trends, a publicly available tool that provides relative search frequency for queried terms, to find searches for chest pain from January 2010 to June 2017 in the United States, the United Kingdom, and Australia. For the United States, results were obtained by state. These data were compared with publicly available prevalence data from the US Centers for Disease Control and Prevention of CHD hospitalizations by state for the same period. The same terms were used to evaluate seasonal and diurnal variation. Data were analyzed from July 2017 to October 2017. Main Outcomes and Measures Correlation of search engine query for chest pain symptoms with temporal and geographic epidemiology. Results State-by-state comparisons with reported CHD hospitalization were correlated (R = 0.81; P < .001). Significant monthly variation was appreciated in all countries studied, with the United States, United Kingdom, and Australia showing an 11% to 39% increase in search frequency in winter months compared with summer months. Diurnal variation showed a morning peak for search between local time 6 am and 8 am, with a greater than 100% increase seen in peak searching hours, which was consistent among the 3 countries studied. Conclusions and Relevance Relative search frequency closely correlated with CHD epidemiology. This may have important implications for search engines as a resource for patients and a potential early-detection mechanism for physicians moving forward.

Effect of Promotion via Social Media on Access of Articles in an Academic Medical Journal: A Randomized Controlled Trial. ACADEMIC MEDICINE : JOURNAL OF THE ASSOCIATION OF AMERICAN MEDICAL COLLEGES 2019; 94:1546-1553. [PMID: 31149923 DOI: 10.1097/acm.0000000000002811] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/09/2023]
Abstract
PURPOSE To study the effect of a planned social media promotion strategy on access of online articles in an established academic medical journal. METHOD This was a single-masked, randomized controlled trial using articles published in Mayo Clinic Proceedings, a large-circulation general/internal medicine journal. Articles published during the months of October, November, and December 2015 (n = 68) were randomized to social media promotion (SoMe) using Twitter, Facebook, and LinkedIn or to no social media promotion (NoSoMe), for 30 days (beginning with the date of online article publication). Journal website visits and full-text article downloads were compared for 0-30 and 31-60 days following online publication between SoMe versus NoSoMe using a Wilcoxon rank-sum test. RESULTS Website access of articles from 0 to 30 days was significantly higher in the SoMe group (n = 34) compared with the NoSoMe group (n = 34): 1,070 median downloads versus 265, P < .001. Similarly, full-text article downloads from 0-30 days were significantly higher in the SoMe group: 1,042 median downloads versus 142, P < .001. Compared with the NoSoMe articles, articles randomized to SoMe received a greater number of website visits via Twitter (90 vs 1), Facebook (526 vs 2.5), and LinkedIn (31.5 vs 0)-all P < .001. CONCLUSIONS Articles randomized to SoMe were more widely accessed compared with those without social media promotion. These findings show a possible role, benefit, and need for further study of a carefully planned social media promotion strategy in an academic medical journal.

Abstract
Fibrosing mediastinitis is a rare, often debilitating and potentially lethal disease characterized by an exuberant fibroinflammatory response within the mediastinum. Patients typically present with insidious symptoms related to compression of adjacent structures including the esophagus, heart, airways, and cardiac vessels. Fibrosing mediastinitis is most often triggered by Histoplasmosis infection; however, antifungal and anti-inflammatory therapies are largely ineffective. While structural interventions aimed at alleviating obstruction can provide significant palliation, surgical interventions are challenging with high mortality and clinical experience with percutaneous interventions is limited. Here, we will review the presentation, natural history, and treatment of fibrosing mediastinitis, placing particular emphasis on catheter-based therapies.

Abstract
Mental and physical stress is thought to play an important causative factor in apical ballooning syndrome (ABS) likely secondary to the vasomotor dysfunction. However, there are currently few data related to the impact of physical stress in this unique cardiomyopathy.A total 18 patients, including 8 females with history of ABS and 10 post-menopausal controls, underwent physical and mental tests. Assessments included the pain-induced peripheral artery tonometry scores (PIPATs) and mental stress peripheral artery tonometry scores (PATs).Compared with control group, PIPATs were significantly attenuated in patients with ABS in both baseline and post-mental stress (0.94 ± 0.08 vs1.30 ± 0.54, P <.05 and 0.87 ± 0.19 vs1.24 ± 0.21 P = .01, respectively); mental stress PATs were significantly lower in patients with ABS, both in Stroop test (0.79 ± 0.30 vs 1.24 ± 0.43, P = .01) and arithmetic test (0.91 ± 0.27 vs 1.36 ± 0.57, P = .01). PIPATs correlated significantly with mental stress PATs, both in arithmetic and Stroop test (P <.05).The PIPATs were attenuated in female with history of ABS and the vascular response to pain may provide a different pathogenesis mechanism on detecting patients with ABS.

The Impact of Social Media on Negative Online Physician Reviews: an Observational Study in a Large, Academic, Multispecialty Practice. J Gen Intern Med 2019; 34:98-101. [PMID: 30374885 PMCID: PMC6318187 DOI: 10.1007/s11606-018-4720-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 08/30/2018] [Accepted: 10/19/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND Online reviews of physicians are becoming increasingly common, however no correlation of these reviews to formal patient satisfaction surveys. With the explosion of social media, it is unknown as to how this form of communication may have a role in potentially managing and addressing the search position of negative online reviews. METHODS We obtained a list of 102 physicians with negative online reviews between September 2014 and December 2014. Social media uptake and average Google search position of the physician and their respective negative online reviews were assessed from January 2015 through January 2017. RESULTS Fifty-four (53%) physicians had any social media presence in January 2015. All 102 physicians were subsequently offered social media coaching by the Mayo Clinic Center for Social Media which resulted in an increase to 90% of these physicians participating in social media by January 2017. The average Google search position for the negative online reviews was significantly reduced from 5.2 ± 2.5 to 14.3 ± 11.3 (P < 0.001) from 2015 to 2017. There was a moderate increase in Doximity uptake during that time increasing from 11% of the physicians having a claimed profile to 80%. There were non-significant reductions in the average Google search position - 9.7 ± 11.3 in the physicians who had an existing a social media presence versus those who were not on social media - 4.2 ± 2.2 (P = 0.11). CONCLUSIONS Physician social media presence can reduce the bearing of negative online comments by decreasing the search position of these comments.

Contributors Toward Pulmonary Vein Restenosis Following Successful Intervention. JACC Clin Electrophysiol 2018; 4:547-552.

Abstract
OBJECTIVES This study sought to identify clinical and procedural risk factors associated with pulmonary vein (PV) restenosis. BACKGROUND Pulmonary vein stenosis (PVS) is a rare but morbid complication of PV isolation for atrial fibrillation (AF) ablation. Interventions such as PV balloon angioplasty (BA) or stenting achieve excellent acute success; however, subsequent restenosis is common. METHODS A total of 113 patients underwent invasive treatment for severe PVS between 2000 and 2014 and were followed prospectively. Baseline patient and lesion characteristics were abstracted from chart review and analyzed. Univariate and multivariate analyses were performed using patient and procedural characteristics to determine which factors were associated with an increased risk for subsequent PV restenosis. RESULTS Over a median follow-up of 4.6 years there was PVS recurrence in 75 veins; 52 veins (57%) were treated with index BA and 23 veins were treated with stenting. After multivariate analysis, the only patient factor that was significantly associated with restenosis was a history of more than 1 AF ablation (hazard ratio [HR]: 1.91; 95% confidence interval [CI]: 1.07 to 3.41; p = 0.03). Multivariate analysis on a per-vein level demonstrated a significantly lower risk of restenosis in veins treated with a stent (HR: 2.84; 95% CI: 1.75 to 4.61; p < 0.0001). In veins treated with BA alone, inflation of the balloon to higher atmospheres significantly reduced the risk of recurrence (HR: 0.87; 95% CI: 0.78 to 0.98; p = 0.02). CONCLUSIONS Restenosis is common after a successful PV intervention and the risk of restenosis is highest in those with a history of multiple AF ablations and in those treated with BA. Proceduralists should take into account the number of AF ablations a patient has undergone and should strongly consider stent deployment when intervening on PVS to reduce risk of restenosis.

Abstract
BACKGROUND Digital health tools have been associated with improvement of cardiovascular disease (CVD) risk factors and outcomes; however, the differential use of these technologies among various ethnic and economic classes is not well known. OBJECTIVE To identify the effect of socioeconomic environment on usage of a digital health intervention. METHODS A retrospective secondary cross-sectional analysis of a workplace digital health tool use, in association with a change in intermediate markers of CVD, was undertaken over the course of one year in 26,188 participants in a work health program across 81 organizations in 42 American states between 2011 and 2014. Baseline demographic data for participants included age, sex, race, home zip code, weight, height, blood pressure, glucose, lipids, and hemoglobin A1c. Follow-up data was then obtained in 90-day increments for up to one year. Using publicly available data from the American Community Survey, we obtained the median income for each zip code as a marker for socioeconomic status via median household income. Digital health intervention usage was analyzed based on socioeconomic status as well as age, gender, and race. RESULTS The cohort was found to represent a wide sample of socioeconomic environments from a median income of US $11,000 to $171,000. As a whole, doubling of income was associated with 7.6% increase in log-in frequency. However, there were marked differences between races. Black participants showed a 40.5% increase and Hispanic participants showed a 57.8% increase in use with a doubling of income, compared to 3% for Caucasian participants. CONCLUSIONS The current study demonstrated that socioeconomic data confirms no relevant relationship between socioeconomic environment and digital health intervention usage for Caucasian users. However, a strong relationship is present for black and Hispanic users. Thus, socioeconomic environment plays a prominent role only in minority groups that represent a high-risk group for CVD. This finding identifies a need for digital health apps that are effective in these high-risk groups.

Abstract
Online physician reviews have become increasingly prevalent and are a common means by which patients explore medical options online. Currently, there are no data comparing physicians with negative online reviews and those without negative reviews. We sought to compare industry-vetted patient satisfaction surveys (PSSs), such as Press Ganey (PG) PSSs, between those physicians with negative online reviews and those without negative reviews. Overall, there were 113 unique individuals with negative online reviews from September 1, 2014, to December 31, 2014, with 8 being nonphysicians. We matched 113 physicians in similar departments/divisions. We obtained PG PSS scores of both groups and compared the mean scores of the 2 groups. Press Ganey PSS scores were available for 98 physicians with negative online reviews compared with 82 matched physicians without negative online reviews. The mean raw PG PSS scores were not different between the 2 groups (4.05; 95% CI, 3.99-4.11 vs 4.04; 95% CI, 3.97-4.11; P=.92). We also noted no difference in mean scores on questions related to physician-patient communication and interaction skills between those with poor online reviews and those without (4.38; 95% CI, 4.32-4.43 vs 4.41; 95% CI, 4.35-4.47; P=.42). However, there was a significantly lower non-physician-specific mean in those with negative online reviews (3.91; 95% CI, 3.84-3.97) vs those without negative online reviews (4.01; 95% CI, 3.95-4.09) (P=.02). Here, we provide data indicating that online physician reviews do not correlate to formal institutional PG PSS. Furthermore, physicians with negative online reviews have lower scores on non-physician-specific variables included in the PG PSSs, emphasizing that these discrepancies can negatively affect overall patient experience, online physician reviews, and physician reputation. It is prudent that an improved mechanism for online ratings be implemented to better inform patients about a physician's online reputation.

Abstract
Acute coronary syndromes (ACSs) account for a large proportion of disease burden in the United States and worldwide, and our understanding of ACS management continues to evolve. In this review we take a practical approach to evaluating and treating a patient with ACS, focusing on the optimal timing and methods of coronary reperfusion. Beginning with initial assessment and risk stratification, a provider managing the patient with ACS must be able to expeditiously decide on and implement the correct guideline-directed pathway to optimize outcomes. With an ever-growing body and weight of knowledge in this field, the clinician is tasked with several challenges. First, there are a variety of pathways of care to be considered; second, adjunctive medical therapies are expanding; and third, when coupled with the multiple combinations of adjunctive supportive therapies for revascularization, the variety of potential therapeutic options can be overwhelming and confusing. Herein, we carefully review all the relevant guidelines and the contributing literature, taking a 4-step approach: (1) review the importance of risk stratification before engaging in a particular strategy of care, (2) define the reperfusion strategies available, (3) review the specific agents (antiplatelet and anticoagulant) that support reperfusion strategies, and (4) apply the strategies of care in the context of the clinical presentation.

Abstract
BACKGROUND MOTS-c is one of the newly identified mitochondrial-derived peptides which play a role in regulating metabolic homeostasis. The current study aimed to investigate whether circulating MOTS-c levels are also associated with endothelial dysfunction(ED) in patients without significant structural coronary lesions. METHODS Forty patients undergoing coronary angiography and endothelial function testing for clinical indications of recurrent angina with no structural coronary lesions were included in the study. They were divided into two groups based on coronary blood flow response to intracoronary acetylcholine (ACh) as normal endothelial function (≥ 50% increase from baseline) or ED, (n=20 each). Aortic plasma samples were collected at the time of catheterization for analysis of circulating MOTS-c levels by ELISA. The effect of MOTS-c on vascular reactivity was assessed in organ chambers using aortic rings collected from rats and renal artery stenosis (RAS) mice. RESULTS Baseline characteristics were similar between the two groups. MOTS-c plasma levels were lower in patients with ED compared with patients with normal endothelial function (p=0.007). Furthermore, plasma MOTS-c levels were positively correlated with microvascular (p=0.01) and epicardial (p=0.02) coronary endothelial function. Although MOTS-c did not have direct vasoactive effects, pretreating aortic rings from rats or RAS mice with MOTS-c (2μg/ml) improved vessel responsiveness to ACh compared with vessels without MOTS-c treatment. CONCLUSION Lower circulating endogenous MOTS-c levels in human subjects are associated with impaired coronary endothelial function. In rodents, MOTS-c improves endothelial function in vitro. Thus, MOTS-c represents a novel potential therapeutic target in patients with ED.

Abstract
BACKGROUND Digital health interventions (DHI) have been shown to improve intermediates of cardiovascular health, but their impact on cardiovascular (CV) outcomes has not been fully explored. The aim of this study was to determine whether DHI administered during cardiac rehabilitation (CR) would reduce CV-related emergency department (ED) visits and rehospitalizations in patients after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). METHODS We randomized patients undergoing CR following ACS and PCI to standard CR (n=40) or CR+DHI (n=40) for 3 months with 3 patients withdrawing from CR prior to initiation in the treatment arm and 6 in the control group. The DHI incorporated an online and smartphone-based CR platform asking the patients to report of dietary and exercise habits throughout CR as well as educational information toward patients' healthy lifestyles. We obtained data regarding ED visits and rehospitalizations at 180 days, as well as other metrics of secondary CV prevention at baseline and 90 days. RESULTS Baseline demographics were similar between the groups. The DHI+CR group had improved weight loss compared to the control group (-5.1±6.5 kg vs. -0.8±3.8 kg, respectively, P=.02). Those in the DHI+CR group also showed a non-significant reduction in CV-related rehospitalizations plus ED visits compared to the control group at 180 days (8.1% vs 26.6%; RR 0.30, 95% CI 0.08-1.10, P=.054). CONCLUSIONS The current study demonstrated that complementary DHI significantly improves weight loss, and might offer a method to reduce CV-related ED visits plus rehospitalizations in patients after ACS undergoing CR. The study suggests a role for DHI as an adjunct to CR to improve secondary prevention of CV disease. TRIAL REGISTRATION This trial is registered at clinicaltrials.gov (NCT01883050).

Abstract
With more than 300 million monthly active users, Twitter is a powerful social media tool in healthcare, yet the characterization of an academic healthcare Twitter account remains poor to date. We assessed basic gender and geographic data on the account's "followers," as well as categorization of each tweet based on content type. We analyzed the impressions, engagements, retweets, favorites, replies, hashtag clicks, and detail expansions using both Sprinklr and Twitter Analytics. Over a period of 12 months, the account amassed 1,235 followers, with 54 percent being male and 68 percent residing in the United States. Of the 1,635 tweets sent out over the life of the account, we report more than 382,464 impressions, 6,023 engagements, 1,255 retweets, 776 favorites, and 1,654 embedded media clicks in this period. When broken down by tweet category, publication tweets garnered the highest engagement with an estimated mean number of clicks per tweet of 8.2 ± 81.9. Original content had higher total engagement per tweet than retweeted material (2.8 ± 9.2 vs. 0.2 ± 0.9 engagements per tweet; p < 0.0001). Tweets regarding internal, national, and continuing medical education events had similar engagement. Herein is the first publication within the medical literature describing a "case series" of cardiovascular tweets over 12 months. We highlight a rapidly emerging group of interactive followers, a successful means by which to disseminate and engage in breaking topics throughout the cardiovascular field, and the importance of combining physician-led knowledge with intermittent marketing messages.

Abstract
Background:
The frequency of pulmonary vein stenosis (PVS) after ablation for atrial fibrillation has decreased, but it remains a highly morbid condition. Although treatment strategies including pulmonary vein dilation and stenting have been described, the long-term impacts of these interventions are unknown. We evaluated the presentation of severe PVS, and examined the risk for restenosis after intervention using either balloon angioplasty (BA) alone or BA with stenting.
Methods:
This was a prospective, observational study of 124 patients with severe PVS evaluated between 2000 and 2014.
Results:
All 124 patients were identified as having severe PVS by computed tomography in 219 veins. One hundred two patients (82%) were symptomatic at diagnosis. The most common symptoms were dyspnea (67%), cough (45%), fatigue (45%), and decreased exercise tolerance (45%). Twenty-seven percent of patients experienced hemoptysis. Ninety-two veins were treated with BA, 86 were treated with stenting, and 41 veins were not treated. A 94% acute procedural success rate was observed and did not differ by initial management. Major procedural complications occurred in 4 of the 113 patients (3.5%) who underwent invasive assessment, and minor complications occurred in 15 patients (13.3%). Overall, 42% of veins developed restenosis including 27% of veins (n=23) treated with stenting and 57% of veins (n=52) treated with BA. The 3-year overall rate of restenosis was 37%, with 49% of BA-treated veins and 25% of stented veins developing restenosis (hazard ratio, 2.77; 95% confidence interval, 1.72–4.45;
P
<0.001). After adjustment for age, CHA2DS2-VASc score, hypertension, and the time period of the study, there was still a significant difference in the risk of restenosis for BA versus stenting (hazard ratio, 2.46; 95% confidence interval, 1.47–4.12;
P
<0.001).
Conclusions:
The diagnosis of PVS is challenging because of nonspecific symptoms and the need for dedicated pulmonary vein imaging. There is no difference in acute success by type of initial intervention; however, stenting significantly reduces the risk of subsequent pulmonary vein restenosis in comparison with BA.

Prevalence of Coronary Microvascular Dysfunction Among Patients With Chest Pain and Nonobstructive Coronary Artery Disease. JACC Cardiovasc Interv 2016; 8:1445-1453. [PMID: 26404197 DOI: 10.1016/j.jcin.2015.06.017] [Citation(s) in RCA: 307] [Impact Index Per Article: 38.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2015] [Revised: 06/11/2015] [Accepted: 06/18/2015] [Indexed: 10/23/2022]
Abstract
OBJECTIVES This study assessed the prevalence of coronary microvascular abnormalities in patients presenting with chest pain and nonobstructive coronary artery disease (CAD). BACKGROUND Coronary microvascular abnormalities mediate ischemia and can lead to an increased risk of cardiovascular events. METHODS Using an intracoronary Doppler guidewire, endothelial-dependent microvascular function was examined by evaluating changes in coronary blood flow in response to acetylcholine, whereas endothelial-independent microvascular function was examined by evaluating changes in coronary flow velocity reserve in response to intracoronary adenosine. Patients were divided into 4 groups depending on whether they had a normal (+) or abnormal (-) coronary blood flow (CBF) in response to acetylcholine (Ach) and a normal (+) or abnormal (-) coronary flow velocity reserve (CFR) in response to adenosine (Adn): CBFAch+, CFRAdn+ (n = 520); CBFAch-, CFRAdn+ (n = 478); CBFAch+, CFRAdn- (n = 173); and CBFAch-, CFRAdn- (n = 268). RESULTS Two-thirds of all patients had some sort of microvascular dysfunction. Women were more prevalent in each group (56% to 82%). Diabetes was uncommon in all groups (7% to 12%), whereas hypertension and hyperlipidemia were relatively more prevalent in each group, although rates for most conventional cardiovascular risk factors did not differ significantly between groups. There were no significant differences in the findings of noninvasive functional testing between groups. In a multivariable analysis, age was the only variable that independently predicted abnormal microvascular function. CONCLUSIONS Patients with chest pain and nonobstructive CAD have a high prevalence of coronary microvascular abnormalities. These abnormalities correlate poorly with conventional cardiovascular risk factors and are dissociated from the findings of noninvasive functional testing.

Workplace Digital Health Is Associated with Improved Cardiovascular Risk Factors in a Frequency-Dependent Fashion: A Large Prospective Observational Cohort Study. PLoS One 2016; 11:e0152657.

Abstract
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the US. Emerging employer-sponsored work health programs (WHP) and Digital Health Intervention (DHI) provide monitoring and guidance based on participants' health risk assessments, but with uncertain success. DHI--mobile technology including online and smartphone interventions--has previously been found to be beneficial in reducing CVD outcomes and risk factors, however its use and efficacy in a large, multisite, primary prevention cohort has not been described to date. We analyzed usage of DHI and change in intermediate markers of CVD over the course of one year in 30,974 participants of a WHP across 81 organizations in 42 states between 2011 and 2014, stratified by participation log-ins categorized as no (n = 14,173), very low (<12/yr, n = 12,260), monthly (n = 3,360), weekly (n = 651), or semi-weekly (at least twice per week). We assessed changes in weight, waist circumference, body mass index (BMI), blood pressure, lipids, and glucose at one year, as a function of participation level. We utilized a Poisson regression model to analyze variables associated with increased participation. Those with the highest level of participation were slightly, but significantly (p<0.0001), older (48.3±11.2 yrs) than non-participants (47.7±12.2 yr) and more likely to be females (63.7% vs 37.3% p<0.0001). Significant improvements in weight loss were demonstrated with every increasing level of DHI usage with the largest being in the semi-weekly group (-3.39±1.06 lbs; p = 0.0013 for difference from weekly). Regression analyses demonstrated that greater participation in the DHI (measured by log-ins) was significantly associated with older age (p<0.001), female sex (p<0.001), and Hispanic ethnicity (p<0.001). The current study demonstrates the success of DHI in a large, community cohort to modestly reduce CVD risk factors in individuals with high participation rate. Furthermore, participants previously underrepresented in WHPs (females and Hispanics) and those with an increased number of CVD risk factors including age and elevated BMI show increased adherence to DHI, supporting the use of this low-cost intervention to improve CVD health.

Utility of both carotid intima-media thickness and endothelial function for cardiovascular risk stratification in patients with angina-like symptoms. Int J Cardiol 2015; 190:90-8. [PMID: 25918056 DOI: 10.1016/j.ijcard.2015.04.124] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2014] [Revised: 03/12/2015] [Accepted: 04/15/2015] [Indexed: 12/23/2022]
Abstract
BACKGROUND Myocardial perfusion scintigraphy (MPS) is used widely to assess cardiovascular risk in patients with chest pain. The utility of carotid intima-media thickness (CIMT) and endothelial function as assessed by reactive hyperemia-peripheral arterial tonometry index (RHI) in risk stratifying patients with angina-like symptoms needs to be defined. We investigated whether the addition of CIMT and RHI to Framingham Cardiovascular Risk Score (FCVRS) and MPS improves comprehensive cardiovascular risk prediction in patients presenting with angina-like symptoms. METHODS We enrolled 343 consecutive patients with angina-like symptoms suspected of having stable angina. MPS, CIMT, and RHI were performed and patients were followed for cardiovascular events for a median of 5.3 years (range 4.4-6.2). Patients were stratified by FCVRS and MPS. RESULTS During the follow-up, 57 patients (16.6%) had cardiovascular events. Among patients without perfusion defect, low RHI was significantly associated with cardiovascular events in the intermediate and high FCVRS groups (hazard ratio (HR) [95% confidence interval (CI)] of RHI ≤ 2.11 was 6.99 [1.34-128] in the intermediate FCVRS group and 6.08 [1.08-114] in the high FCVRS group). Furthermore, although MPS did not predict, only RHI predicted hard cardiovascular events (cardiovascular death, myocardial infarction, and stroke) independent from FCVRS, and adding RHI to FCVRS improved net reclassification index (20.9%, 95% CI 0.8-41.1, p = 0.04). Especially, RHI was significantly associated with hard cardiovascular events in the high FCVRS group (HR [95% CI] of RHI ≤ 1.93 was 5.66 [1.54-36.4], p = 0.007). CONCLUSIONS Peripheral endothelial function may improve discrimination in identifying at-risk patients for future cardiovascular events when added to FCVRS-MPS-based risk stratification.

Digital health interventions for the prevention of cardiovascular disease: a systematic review and meta-analysis. Mayo Clin Proc 2015; 90:469-80. [PMID: 25841251 PMCID: PMC4551455 DOI: 10.1016/j.mayocp.2014.12.026] [Citation(s) in RCA: 213] [Impact Index Per Article: 23.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2014] [Accepted: 12/19/2014] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To assess the potential benefit of digital health interventions (DHIs) on cardiovascular disease (CVD) outcomes (CVD events, all-cause mortality, hospitalizations) and risk factors compared with non-DHIs. PATIENTS AND METHODS We conducted a systematic search of PubMed, MEDLINE, EMBASE, Web of Science, Ovid, CINHAL, ERIC, PsychINFO, Cochrane, and Cochrane Central Register of Controlled Trials for articles published from January 1, 1990, through January 21, 2014. Included studies examined any element of DHI (telemedicine, Web-based strategies, e-mail, mobile phones, mobile applications, text messaging, and monitoring sensors) and CVD outcomes or risk factors. Two reviewers independently evaluated study quality utilizing a modified version of the Cochrane Collaboration risk assessment tool. Authors extracted CVD outcomes and risk factors for CVD such as weight, body mass index, blood pressure, and lipid levels from 51 full-text articles that met validity and inclusion criteria. RESULTS Digital health interventions significantly reduced CVD outcomes (relative risk, 0.61; 95% CI, 0.46-0.80; P<.001; I(2)=22%). Concomitant reductions in weight (-2.77 lb [95% CI, -4.49 to -1.05 lb]; P<.002; I(2)=97%) and body mass index (-0.17 kg/m(2) [95% CI, -0.32 kg/m(2) to -0.01 kg/m(2)]; P=.03; I(2)=97%) but not blood pressure (-1.18 mm Hg [95% CI, -2.93 mm Hg to 0.57 mm Hg]; P=.19; I(2)=100%) were found in these DHI trials compared with usual care. In the 6 studies reporting Framingham risk score, 10-year risk percentages were also significantly improved (-1.24%; 95% CI, -1.73% to -0.76%; P<.001; I(2)=94%). Results were limited by heterogeneity not fully explained by study population (primary or secondary prevention) or DHI modality. CONCLUSION Overall, these aggregations of data provide evidence that DHIs can reduce CVD outcomes and have a positive impact on risk factors for CVD.

Abstract
We currently face a myriad of grand global challenges in fields such as poverty, the environment, education, science, and medicine. However, our current means of dealing with such challenges has fallen short, and ingenious solutions are required to overcome the inherent resistance to progress toward ameliorating such difficulties. Here, we highlight the promises and challenges of international collaboration in achieving success toward these trials. We note prior successes in fields such as education, medicine, science, and environmental issues made to date, yet at the same time we do note deficiencies and shortcomings in these efforts. Hence, the notion of international collaboration should be strengthened and encouraged by governments, non-profit organizations, and others moving forward using creative means to bring talented teams together to tackle these challenges across the globe.

The Mediterranean diet, its components, and cardiovascular disease. Am J Med 2015; 128:229-38. [PMID: 25447615 PMCID: PMC4339461 DOI: 10.1016/j.amjmed.2014.10.014] [Citation(s) in RCA: 482] [Impact Index Per Article: 53.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2014] [Revised: 10/01/2014] [Accepted: 10/02/2014] [Indexed: 12/13/2022]
Abstract
One of the best-studied diets for cardiovascular health is the Mediterranean diet. This consists of fish, monounsaturated fats from olive oil, fruits, vegetables, whole grains, legumes/nuts, and moderate alcohol consumption. The Mediterranean diet has been shown to reduce the burden, or even prevent the development, of cardiovascular disease, breast cancer, depression, colorectal cancer, diabetes, obesity, asthma, erectile dysfunction, and cognitive decline. This diet is also known to improve surrogates of cardiovascular disease, such as waist-to-hip ratio, lipids, and markers of inflammation, as well as primary cardiovascular disease outcomes such as death and events in both observational and randomized controlled trial data. These enhancements easily rival those seen with more established tools used to fight cardiovascular disease such as aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and exercise. However, it is unclear if the Mediterranean diet offers cardiovascular disease benefit from its individual constituents or in aggregate. Furthermore, the potential benefit of the Mediterranean diet or its components is not yet validated by concrete cardiovascular disease endpoints in randomized trials or observational studies. This review will focus on the effects of the whole and parts of the Mediterranean diet with regard to both population-based and experimental data highlighting cardiovascular disease morbidity or mortality and cardiovascular disease surrogates when hard outcomes are not available. Our synthesis will highlight the potential for the Mediterranean diet to act as a key player in cardiovascular disease prevention, and attempt to identify certain aspects of the diet that are particularly beneficial for cardioprotection.

The association between circulating microRNA levels and coronary endothelial function. PLoS One 2014; 9:e109650.

Abstract
Human microRNAs (miRs) have been implicated in human diseases presumably through the downregulation and silencing of targeted genes via post-translational modifications. However, their role in the early stage of coronary atherosclerosis is not known. The aim of this study was to test the hypothesis that patients with early atherosclerosis and coronary endothelial dysfunction (CED) have alterations in transcoronary miR gradients. Patients underwent coronary angiography and endothelial function testing in the cardiac catheterization laboratory. Patients were divided into abnormal (n = 26) and normal (n = 22) microvascular coronary endothelial function based on intracoronary response to infused acetylcholine measured as a percent change in coronary blood flow (CBF) and arterial diameter. Blood samples were obtained simultaneously from the aorta and coronary sinus at the time of catheterization for RNA isolation, and miR subsequently assessed. Baseline characteristics were similar in both groups. Patients with microvascular CED displayed transcoronary gradients significantly elevated in miR-92a and miR-133 normalized to C-elegans-39 miR. Percent change in CBF and the transcoronary gradient of miR-133 displayed a significant inverse correlation (r2 = 0.11, p = 0.03). Thus, we present novel data whereupon selected miRs demonstrate elevated transcoronary gradients in patients with microvascular CED. The current findings support further studies on the mechanistic role of miRs in coronary atherosclerosis and in humans.
