ABSTRACT

BACKGROUND: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has significant health implications. Anemia is usually an unseen comorbidity, which could significantly affect outcomes in AECOPD patients, and there is limited data to support this. We conducted this study to assess the effect of anemia on this patient population. METHODS: We performed a retrospective cohort study using the National (Nationwide) Inpatient Sample (NIS) data from 2008 to 2014. Patients with AECOPD and anemia with age >40 years were identified using appropriate International Classification of Diseases, Ninth Revision (ICD-9) codes, excluding transfer out to other hospitals. We calculated the Charlson Comorbidity Index as a measure of associated comorbidities. We analyzed bivariate group comparisons in patients with and without anemia. Odds ratios were calculated using multivariate logistic and linear regression analysis using SAS version 9.4 (2013; SAS Institute Inc. Cary, North Carolina, United States). RESULTS: Among 3,331,305 patients hospitalized with AECOPD, 567,982 (17.0%) had anemia as a comorbidity. The majority of patients were elderly, women, and white. After adjusting for potential confounders in regression, mortality (adjusted OR (aOR) 1.25, 95%CI: 1.18-1.32), length of hospital stay (ß 0.79, 95%Cl 0.76-0.82), and hospitalization cost (ß 6873, 95%Cl 6437-7308) were significantly higher in patients with anemia. In addition, patients with anemia required significantly higher blood transfusion (aOR 16.9, 95%CI 16.1-17.8), invasive ventilator support (aOR 1.72, 95%CI 1.64-1.79), and non-invasive ventilator support (aOR 1.21, 95%CI 1.17-1.26). CONCLUSION: In this first retrospective largest cohort study on this topic, we find anemia is a significant comorbidity associated with adverse outcomes and healthcare burden in hospitalized AECOPD patients. We should focus on close monitoring and management of anemia to improve the outcomes in this population.

ABSTRACT

Background: District Health Authority in Ahmedabad, Gujarat has introduced Project Lifeline, 12-lead portable ECG devices across all primary health centers (PHC) in the district to screen cardiac abnormalities among high-risk and symptomatic adults for providing primary management and proper timely referral. The prime purpose of the study was to assess the cost-effectiveness of portable ECG for the screening of cardiovascular diseases (CVD) among high-risk and symptomatic adults at the PHC in Ahmedabad, Gujarat. Methods: Cost-effective analysis was conducted using a societal perspective. An incremental costing approach was adapted, and cost-effectiveness analysis was done using a decision-analytic model. We surveyed 73 patients who screened positive for cardiac abnormality, documented the type of ECG abnormalities, and diagnosed CVD. The program cost was obtained from the implementers. Transition probabilities were derived from primary data supported by expert opinion for the intervention arm, while a systematic search of the literature was undertaken to derive transition probabilities for the control arm. Results: The ECG screening at PHC saves 2.90 life years at an incremental cost of 89.97 USD (6657.47 INR), yielding a cost-effectiveness ratio of 31.07 USD (2,299.06 INR) per life-year saved, which is below the willingness to pay threshold. The budget impact analysis was also performed. Results are sensitive to the relative risk reduction associated with the non-participation and the cost of initial screening. Conclusion: Cost-effectiveness analysis clearly shows that the facility to screen cardiac abnormality at the PHC level is highly recommended for high-risk adults and symptomatic cases.

ABSTRACT

BACKGROUND: We hypothesized that anatomical healing in superior labrum anterior to posterior (SLAP) repair is associated with good clinical outcome. The purposes of this study were to assess the failure rate of anatomical healing after arthroscopic repair of SLAP lesions using computed tomography arthrography (CTA), investigate correlation of the rate with clinical outcomes, and identify prognostic factors for anatomical failure following SLAP repair. METHODS: We retrospectively evaluated the outcome of 43 patients at a minimum follow-up of 1 year after arthroscopic surgery for SLAP lesions or SLAP lesions associated with Bankart lesions. Twenty-eight patients underwent isolated SLAP repair and 15 patients underwent Bankart repair with SLAP repair. The anatomical outcome was assessed using CTA at 1 year after surgery. Clinical outcomes including visual analogue scale for pain and satisfaction and Constant score were assessed at the final follow-up. We investigated clinical failure that was defined as stiffness, loss of maximum rotation, deterioration of pain, and/or need for revision of surgery. RESULTS: Anatomical failure occurred in 32.6% of patients (14/43), whereas 16.3% of patients (7/43) had clinical failure. Clinicoradiological assessment revealed that clinical failure occurred only in 7.1% of patients (1/14) with unhealed SLAP lesions, whereas it occurred in 20.7% of patients (6/29) with healed SLAP lesions. Isolated SLAP repair resulted in a higher risk of anatomical failure (risk ratio, 7.0) than combined SLAP repair (p = 0.015). Nonoverhead activities were associated with higher risk of anatomical failure (risk ratio, 2.9; p = 0.041). Patients above 35 years of age had more risk of anatomical failure (risk ratio, 3.5; p = 0.010). Clinical outcomes significantly improved regardless of anatomical failure (p < 0.001) and were not significantly different between unhealed and healed repairs (all p > 0.05). CONCLUSIONS: Since patients with unhealed SLAP lesions had less clinical failure than patients with healed SLAP lesions, anatomical healing does not seem essential for better clinical outcome of SLAP II repair, especially in patients with higher healing failure risk (isolated SLAP repair, nonoverhead activities, and above 35 years of age). Therefore, we believe the indications of SLAP repair should be narrowed to avoid overtreatment.

ABSTRACT

Importance: The role of coronary artery calcium (CAC) testing for guiding preventive strategies among women at low cardiovascular disease (CVD) risk based on the American College of Cardiology and American Heart Association CVD prevention guidelines is unclear. Objective: To assess the potential utility of CAC testing for CVD risk estimation and stratification among low-risk women. Design, Setting, and Participants: Women with 10-year atherosclerotic CVD (ASCVD) risk lower than 7.5% from 5 large population-based cohorts: the Dallas Heart Study (United States), the Framingham Heart Study (United States), the Heinz Nixdorf Recall study (Germany), the Multi-Ethnic Study of Atherosclerosis (United States), and the Rotterdam Study (the Netherlands). The 5 cohorts were selected based on the availability of CAC data in a sizable group of low-risk women from the general population together with the long detailed follow-up data. Across the cohorts, events were assessed from the date of CAC scan (performed from 1998 through 2006) until January 1, 2012; January 1, 2014; or March 6, 2015. Fixed-effects meta-analysis was conducted to combine the results of the 5 studies. Exposures: CAC score by computed tomography. Main Outcomes and Measures: Main outcome was incident ASCVD, including nonfatal myocardial infarction, coronary heart disease (CHD) death, and stroke. Association of CAC with ASCVD was examined using Cox proportional hazards models. To assess whether CAC was associated with improved ASCVD risk predictions beyond the traditional risk factors, the C statistic and the continuous net reclassification improvement (cNRI) index were calculated. Results: Among 6739 women with low ASCVD risk from the 5 studies, mean age ranged from 44 to 63 years and CAC was present in 36.1%. Across the cohorts, median follow-up ranged from 7.0 to 11.6 years. A total of 165 ASCVD events occurred (64 nonfatal myocardial infarctions, 29 CHD deaths, and 72 strokes), with the ASCVD incidence rates ranging from 1.5 to 6.0 per 1000 person-years. Compared with the absence of CAC (CAC = 0), presence of CAC (CAC >0) was associated with an increased risk of ASCVD (incidence rates per 1000 person-years, 1.41 for CAC absence vs 4.33 for CAC presence; difference, 2.92 [95% CI, 2.02-3.83]; multivariable-adjusted hazard ratio, 2.04 [95% CI, 1.44-2.90]). The addition of CAC to traditional risk factors improved the C statistic from 0.73 (95% CI, 0.69-0.77) to 0.77 (95% CI, 0.74-0.81) and provided a cNRI of 0.20 (95% CI, 0.09-0.31) for ASCVD prediction. Conclusions and Relevance: Among women at low ASCVD risk, CAC was present in approximately one-third and was associated with an increased risk of ASCVD and modest improvement in prognostic accuracy compared with traditional risk factors. Further research is needed to assess the clinical utility and cost-effectiveness of this additional accuracy.

ABSTRACT

Left ventricular (LV) mass and geometry are associated with risk of cardiovascular disease (CVD). We sought to determine whether LV mass and geometry contribute to risk prediction for CVD in adults aged ≥65 years of the Cardiovascular Health Study. We indexed LV mass to body size, denoted as LV mass index (echo-LVMI), and we defined LV geometry as normal, concentric remodeling, and eccentric or concentric LV hypertrophy. We added echo-LVMI and LV geometry to separate 10-year risk prediction models containing traditional risk factors and determined the net reclassification improvement (NRI) for incident coronary heart disease (CHD), CVD (CHD, heart failure [HF], and stroke), and HF alone. Over 10 years of follow-up in 2,577 participants (64% women, 15% black, mean age 72 years) for CHD and CVD, the adjusted hazards ratios for a 1-SD higher echo-LVMI were 1.25 (95% CI 1.14 to 1.37), 1.24 (1.15 to 1.33), and 1.51 (1.40 to 1.62), respectively. Addition of echo-LVMI to the standard model for CHD resulted in an event NRI of -0.011 (95% CI -0.037 to 0.028) and nonevent NRI of 0.034 (95% CI 0.008 to 0.076). Addition of echo-LVMI and LV geometry to the standard model for CVD resulted in an event NRI of 0.013 (95% CI -0.0335 to 0.0311) and a nonevent NRI of 0.043 (95% CI 0.011 to 0.09). The nonevent NRI was also significant with addition of echo-LVMI for HF risk prediction (0.10, 95% CI 0.057 to 0.16). In conclusion, in adults aged ≥65 years, echo-LVMI improved risk prediction for CHD, CVD, and HF, driven primarily by improved reclassification of nonevents.

ABSTRACT

OBJECTIVES: This study sought to determine if coronary artery calcium (CAC) is associated with incident noncardiovascular disease. BACKGROUND: CAC is considered a measure of vascular aging, associated with increased risk of cardiovascular and all-cause mortality. The relationship with noncardiovascular disease is not well defined. METHODS: A total of 6,814 participants from 6 MESA (Multi-Ethnic Study of Atherosclerosis) field centers were followed for a median of 10.2 years. Modified Cox proportional hazards ratios accounting for the competing risk of fatal coronary heart disease were calculated for new diagnoses of cancer, pneumonia, chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD), deep vein thrombosis/pulmonary embolism, hip fracture, and dementia. Analyses were adjusted for age; sex; race; socioeconomic status; health insurance status; body mass index; physical activity; diet; tobacco use; number of medications used; systolic and diastolic blood pressure; total and high-density lipoprotein cholesterol; antihypertensive, aspirin, and cholesterol medication; and diabetes. The outcome was first incident noncardiovascular disease diagnosis. RESULTS: Compared with those with CAC = 0, those with CAC >400 had an increased hazard of cancer (hazard ratio [HR]: 1.53; 95% confidence interval [CI]: 1.18 to 1.99), CKD (HR: 1.70; 95% CI: 1.21 to 2.39), pneumonia (HR: 1.97; 95% CI: 1.37 to 2.82), COPD (HR: 2.71; 95% CI: 1.60 to 4.57), and hip fracture (HR: 4.29; 95% CI: 1.47 to 12.50). CAC >400 was not associated with dementia or deep vein thrombosis/pulmonary embolism. Those with CAC = 0 had decreased risk of cancer (HR: 0.76; 95% CI: 0.63 to 0.92), CKD (HR: 0.77; 95% CI: 0.60 to 0.98), COPD (HR: 0.61; 95% CI: 0.40 to 0.91), and hip fracture (HR: 0.31; 95% CI: 0.14 to 0.70) compared to those with CAC >0. CAC = 0 was not associated with less pneumonia, dementia, or deep vein thrombosis/pulmonary embolism. The results were attenuated, but remained significant, after removing participants developing interim nonfatal coronary heart disease. CONCLUSIONS: Participants with elevated CAC were at increased risk of cancer, CKD, COPD, and hip fractures. Those with CAC = 0 are less likely to develop common age-related comorbid conditions, and represent a unique population of "healthy agers."

ABSTRACT

BACKGROUND: Current discussions about biofilm formation focus on the solid/liquid interface between a medical device and body fluids. Yet it has been shown that gas bubbles (GB) can stably form on ureteral stents in artificial urine and that their fate depends on the stent's surface properties. The liquid/gas interface constitutes an adhesion site for precipitating salts as well as hydrophobic organic molecules. MATERIALS AND METHODS: The surface wettability of polyurethane stents is varied by coating with amorphous hydrogenated carbon (a-C:H). GB and crystalline biofilm formation on the stents are investigated in a novel encrustation device which avoids gravitation- or sample-position-related influences on the results. RESULTS: Bigger and more stable GB form on hydrophobic stents than on hydrophilic, coated stents. Appearance and amount of crystalline deposits differ significantly between the surfaces. With decreasing wettability the number of hollow crystalline spheres and the mass of precipitate increase. CONCLUSIONS: On hydrophobic surfaces, stable GB increase precipitation of salts and become incorporated in the growing encrustation layer in vitro. In contrast, GB quickly lift off from hydrophilic surfaces taking part of the precipitate with them. This self-cleaning mechanism slows down the encrustation process. A similar effect may explain the prolonged complication-free indwelling time of amorphous-carbon coated stents in vivo.

ABSTRACT

BACKGROUND: The aim of this study was to determine the association between cardiovascular health (CVH) in young adulthood and left ventricular (LV) structure and function later in life. METHODS: Participants from the Coronary Artery Risk Development in Young Adults study, which recruited black and white participants aged 18 to 30 years at baseline, were included; echocardiography was performed at year 25. CVH at year 0 was defined on the basis of blood pressure, total cholesterol, fasting glucose, body mass index, smoking status, diet, and physical activity. Two, 1, or 0 points were assigned to each component for ideal, intermediate, and poor levels of each component. Participants were stratified into CVH groups on the basis of point score: ≤ 8 (poor), 9 to 11 (intermediate), and 12 to 14 (ideal). RESULTS: The distribution of CVH at year 0 was as follows: poor, n = 264 (9%); intermediate, n = 1,315 (47%); and ideal, n = 1,224 (44%). Individuals with ideal and intermediate CVH at year 0 had significantly lower LV end-diastolic volume and lower LV mass index at year 25. In participants with ideal and intermediate CVH, the multivariate-adjusted odds ratios for diastolic dysfunction at year 25 was 0.52 (95% CI, 0.37-0.73) and 0.63 (95% CI, 0.46-0.83), respectively, compared with participants with poor CVH. Participants with ideal and intermediate CVH had significantly lower odds for LV hypertrophy; the LV mass index was 5.3 to 8.7 g/m(2.7) lower (P < .001 for both) than in participants with poor CVH. CONCLUSION: Greater levels of CVH in young adulthood are associated with lower LV mass and lower risk for diastolic dysfunction 25 years later.

ABSTRACT

The 2013 American College of Cardiology/American Heart Association cardiovascular disease prevention guidelines represent an important step forward in the risk assessment and management of atherosclerotic cardiovascular disease in clinical practice. Differentiated risk prediction equations for women and black individuals were developed, and convenient 10-year and lifetime risk assessment tools were provided, facilitating their implementation. Lifestyle modification was portrayed as the foundation of preventive therapy. In addition, based on high-quality evidence from randomized controlled trials, statins were prioritized as the first lipid-lowering pharmacologic treatment, and a shared decision-making model between the physician and the patient was emphasized as a key feature of personalized care. After publication of the guidelines, however, important limitations were also identified. This resulted in a constructive scientific debate yielding valuable insights into potential opportunities to refine recommendations, fill gaps in guidance, and better harmonize recommendations within and outside the United States. The latter point deserves emphasis because when guidelines are in disagreement, this may result in nonaction on the part of professional caregivers or nonadherence by patients. In this review, we discuss the key scientific literature relevant to the guidelines published in the year and a half after their release. We aim to provide cohesive, evidence-based views that may offer pathways forward in cardiovascular disease prevention toward greater consensus and benefit the practice of clinical medicine.

ABSTRACT

PURPOSE: Placement of ureteral stents (DJ-stents) may lead to complications. Inappropriate friction properties of the implant are, inter alia, made responsible for primary injuries, injury-related inflammation and a cascade of consecutive side effects. Hydrophilicity is considered to be related to low friction. The question arises, whether the various products on the market show their respective maximum hydrophilicity directly after unwrapping or a pre-use moistening, as already routinely done with the guide wire, is necessary. METHODS: The surface wettability of commercial and experimental DJ-stents was determined by water contact angle (WCA) measurements using the sessile drop method. One reference surface and 11 different stent surface types were tested. In order to determine the influence of moistening on the stents' surface wettability, WCAs were measured twice, with dry, and soaked (30 min, 0.9%-NaCl) specimens. Each sample of a surface type was tested at three different positions to avoid effects of surface heterogeneities. Up to six samples of the same surface type were examined. RESULTS: Mean WCAs on fresh and soaked stent surfaces ranged from 75°-103° and 71°-99°. In every case the WCAs on soaked surfaces were lower. On average the WCAs decrease by 7%, the individual decreases differ considerably, from 2 to 16%. For 7/12 of the examined surface types, the decrease in contact angle is statistically significant with p ≤ 0.01. CONCLUSIONS: DJ-stents freshly unwrapped show less hydrophilic properties compared to DJ-stents soaked in saline. To obtain maximum hydrophilicity at stent placement, DJ-stents should be soaked. The results may advocate a similar approach for other urological equipment.

ABSTRACT

BACKGROUND: Electrocardiographic (ECG) abnormalities and coronary artery calcium (CAC) identify different aspects of subclinical coronary heart disease (CHD). We sought to determine whether ECG abnormalities improve risk prediction for all CHD and fatal CHD events jointly with CAC measures. METHODS: We included 6,406 men and women from the MESA aged 45 to 84 years who were free of cardiovascular disease at the time of enrollment (2000-2002). We stratified participants by presence of ST-T and Q wave abnormalities: any major, any minor/no major, and no major/minor using the Minnesota Code classifications. CAC score was defined into one of the following strata: 0, 1 to 100, 101 to 300, greater than 300. We created risk prediction models using MESA-specific coefficients for traditional risk factors (RFs) and calculated categorical net reclassification improvement (NRI) for all and fatal CHD. RESULTS: Over a median follow-up of 10 years, we observed that the addition of ECG abnormalities to a risk prediction model for all CHD resulted in a categorical NRI of 0.05 (P = .04). For fatal CHD alone, the addition of ECG abnormalities resulted in categorical NRI of 0.09 (P = .02). Addition of ECG abnormalities to a model containing RFs and CAC resulted in categorical NRI of 0.02 (P = .11) for all CHD events. We also observed differences in the association between ECG abnormalities and CHD when stratifying by CAC presence. CONCLUSION: Electrocardiographic abnormalities improved risk prediction for CHD when added to RFs but not when added to CAC. Electrocardiographic abnormalities particularly improved risk prediction for fatal CHD.

ABSTRACT

Statins form the pharmacologic cornerstone of the primary and secondary prevention of atherosclerotic cardiovascular disease. In addition to beneficial cardiovascular effects, statins seem to have multiple non-cardiovascular effects. Although early concerns about statin induced hepatotoxicity and cancer have subsided owing to reassuring evidence, two of the most common concerns that clinicians have are myopathy and diabetes. Randomized controlled trials suggest that statins are associated with a modest increase in the risk of myositis but not the risk of myalgia. Severe myopathy (rhabdomyolysis) is rare and often linked to a statin regimen that is no longer recommended (simvastatin 80 mg). Randomized controlled trials and meta-analyses suggest an increase in the risk of diabetes with statins, particularly with higher intensity regimens in people with two or more components of the metabolic syndrome. Other non-cardiovascular effects covered in this review are contrast induced nephropathy, cognition, cataracts, erectile dysfunction, and venous thromboembolism. Currently, systematic reviews and clinical practice guidelines indicate that the cardiovascular benefits of statins generally outweigh non-cardiovascular harms in patients above a certain threshold of cardiovascular risk. Literature is also accumulating on the potential non-cardiovascular benefits of statins, which could lead to novel applications of this class of drug in the future.

ABSTRACT

A large proportion of cardiovascular events occur in individuals classified by traditional risk factors as "low-risk." Efforts to improve early detection of coronary artery disease among low-risk individuals, or to improve risk assessment, might be justified by this large population burden. The most promising tests for improving risk assessment, or early detection, include the coronary artery calcium (CAC) score, the ankle-brachial index (ABI), and the high-sensitivity C-reactive protein (hsCRP). Data regarding the role of additional testing in low-risk populations to improve early detection or to enhance risk assessment are sparse but suggest that CAC and ABI may be helpful for improving risk classification and detecting the higher-risk people from among those at lower risk. However, in the absence of clinical trials in this patient population, such as has recently been proposed, we do not recommend routine use of any additional testing or screening in low-risk individuals at this time.

ABSTRACT

Transcatheter aortic valve replacement (TAVR) is a revolutionary therapy for patients with aortic stenosis. Large registries and randomized controlled trials have demonstrated that TAVR is safe and effective in patients considered inoperable because of severe comorbidities and those who are high-risk surgical candidates. As TAVR evolves for lower-risk patients, attention will need to focus on reducing the rates of vascular injury, stroke, and paravalvular regurgitation. In this review, we discuss the status of TAVR in clinical practice, including patient selection, preoperative evaluation, techniques, and complications.

ABSTRACT

Subclinical atherosclerosis measured by coronary artery calcium (CAC) is associated with increased risk for multiple cardiovascular disease (CVD) outcomes and non-CVD death simultaneously. The aim of this study was to determine the competing risks of specific CVD events and non-CVD death associated with varying burdens of subclinical atherosclerosis. A total of 3,095 men and 3,486 women from the Multi-Ethnic Study of Atherosclerosis (MESA), aged 45 to 84 years, from 4 ethnic groups were included. Participants were stratified by CAC score (0, 1 to 99, and ≥100). Competing Cox models were used to determine competing cumulative incidences and hazard ratios within a group (e.g., those with CAC scores ≥100) and hazard ratios for specific events between groups (e.g., CAC score ≥100 vs 0). Risks were compared for specific CVD events and also against non-CVD death. In women, during a mean follow-up period of 7.1 years, the hazard ratios for any CVD event compared with a non-CVD death occurring first for CAC score 0 and CAC score ≥100 were 1.40 (95% confidence interval 0.97 to 2.04) and 3.07 (95% confidence interval 2.02 to 4.67), respectively. Coronary heart disease was the most common first CVD event type at all levels of CAC, and coronary heart disease rates were 9.5% versus 1.6% (hazard ratio 6.24, 95% confidence interval 3.99 to 9.75) for women with CAC scores ≥100 compared with CAC scores of 0. Similar results were observed in men. In conclusion, at all levels of CAC, coronary heart disease was the most common first CVD event, and this analysis represents a novel approach to understanding the temporal sequence of cardiovascular events associated with atherosclerosis.

ABSTRACT

The authors sought to determine the prevalence, prospective risk markers, and prognosis associated with diastolic dysfunction in the Coronary Artery Risk Development in Young Adults (CARDIA) Study. The CARDIA Study cohort includes approximately equal proportions of white and black men and women. The authors collected data on risk markers at year 0 (1985-1986), and echocardiography was done at year 5 when the participants were 23-35 years of age. Participants were followed for 20 years (through 2010) for a composite endpoint of all-cause mortality, myocardial infarction, heart failure, and stroke. Diastolic function was defined according to a validated hierarchical classification algorithm. In the 2,952 participants included in the primary analysis, severe diastolic dysfunction was present in 1.1% and abnormal relaxation was present in 9.3%. Systolic blood pressure at year 0 was associated with both severe diastolic dysfunction and abnormal relaxation 5 years later, whereas exercise capacity and pulmonary function abnormalities were associated only with abnormal relaxation 5 years later. After multivariate adjustment, the hazard ratios for the composite endpoint in participants with severe diastolic dysfunction and abnormal relaxation were 4.3 (95% confidence interval: 2.0, 9.3) and 1.6 (95% confidence interval: 1.1, 2.5), respectively. Diastolic dysfunction in young adults is associated with increased morbidity and mortality, and the identification of prospective risk markers associated with diastolic dysfunction could allow for targeted primary prevention efforts.
