Effectiveness of buffered acetylsalicylic acid compared to other drugs in diseases patients in clinical practice: results of the CARDINAL observational retrospective study

Aim. To evaluate the effectiveness of acetylsalicylic acid (ASA) drugs for secondary prevention of atherosclerotic cardiovascular disease (ASCVD) in clinical practice and compare the effectiveness of the Cardiomagnyl with other ASA drugs.Material and methods. This observational, non-interventional, retrospective study included data from electronic medical records of 18199 patients with ASCVD who were divided into 2 following groups: patients who received ASA 75-100 mg (n=9784) and patients who did not receive ASA (n=8325). The prescription rate of ASA, the choice of the first drug, the duration of ASA therapy, the frequency of switching ASA during treatment, and the choice of the second ASA drug when changing therapy were assessed. Due to the heterogeneity of patients in the above groups, to assess the clinical outcomes, propensity score matching was performed and comparable groups were selected to evaluate the effectiveness of ASA drugs 75-100 mg in patients with ASCVD (n= 427) in comparison with patients not receiving ASA (n=427) and to assess the effectiveness of Cardiomagnyl 75 mg (n=1308) in comparison with enterosoluble ASA 100 mg (CRA) (n=1308) taking into account 24 parameters.Results. The average proportion of patients with ASCVD taking ASA drugs was 58%. During treatment, 54% of patients underwent a change in drug therapy from one ASA drug to another. The prescription rate of Cardiomagnyl as a first-choice drug was 33%, and as a second drug when changing therapy — 21%. The duration of Cardiomagnyl therapy was the longest compared to other ASA drugs and amounted to 16,3 months. The incidence of ischemic stroke, myocardial infarction and major adverse cardiovascular events in the group of patients who received ACS 75-100 mg was significantly lower than in patients who did not take ASA drugs and amounted to 4,7% vs 8,7%, 0,9% vs 3,3%, 5,6% vs 11,9%, respectively. Significantly lower incidence of unstable angina (0,8% vs 2,0%), myocardial infarction (1,5% vs 3,9%) and major adverse cardiovascular events (5,4% vs 7,8%) in group of patients who received Cardiomagnyl 75 mg as opposed to enterosoluble ASA.Conclusion. Significant advantages of buffered ASA (Cardiomagnyl) were revealed in comparison with enterosoluble ASA in clinical practice.

THE PREDICTION OF CARDIOVASCULAR EVENTS BY PHENOTYPE OF CENTRAL AND PERIPHERAL BLOOD PRESSURE IN SUBJECTS WITHOUT HYPERTENSION

Objective: Hypertension (HBP) is a common disease with aging, but the rate of recognition or poor control is still high. Until now, most guidelines related to HBP consisted of only peripheral blood pressure (BP) measurement. However, according to many studies, it is known that central BP (CBP) has a clearer relationship than peripheral BP, which can more clearly express an individual's BP status with the prediction of cardiovascular (CV) events. Therefore, we aimed to evaluate the effect of CBP on the prediction of CV events and to investigate the prediction of CV events by phenotype of central and peripheral BP in subjects without hypertension. Design and method: A total of 2910 patients were enrolled from June 2011 to December 2016, and were followed up through October 2022. CBP was measured using radial tonometry. The primary endpoints were composite outcome. Results: The median follow-up period for enrolled patients was 7.5 years. Out of a total of 722 patients (mean age of 52.5 ± 13.7 years) without HBP, 21 patients (2.9%) had events of primary end points during the follow up period. Systolic BP averaged 126 mmHg (±15 mmHg) in the event-free group and 136 mmHg (±15 mmHg) in the CV event group, while CBP measured 115 mmHg (±16 mmHg) in the event-free group and 126 mmHg (±16 mmHg) in the CV event group. In Cox proportional hazards model, CBP and systolic BP, every 10 mmHg increase, showed an increase in risk of 30% and 40% respectively. Isolated central systolic hypertension and both central and peripheral systolic hypertension showed 4.9 % and 6% of the CV event rate, respectively (p = 0.897). Conclusions: Irrespective of the brachial BP status, isolated central hypertension increased CV events. Therefore, to prevent CV events is an essential control not peripheral BP but also CBP.

Нospital outcomes of coronary artery bypass grafting in patients with coronary heart disease with previous percutaneous coronary intervention

Evaluation of the frequency hospital cardiovascular events in groups of patients with stable angina who underwent percutaneous coronary interventions (PCI) with stenting of the arteries before coronary bypass surgery, or who did not have previous myocardial revascularization. The 120 patients with stable angina who underwent routine coronary artery bypass grafting were examined. Group composition: Men 80.8%, age 587.6, duration of coronary heart disease 65.7 years, history of myocardial infarction (MI) 77.5%. Arterial hypertension was present in 92.5%, diabetes mellitus in 12.5% of patients. Multivessel coronary artery disease in 72.5% of patients. 28 (23.4%) patients had previously undergone PCI with stenting of the coronary arteries. The period from PCI to coronary bypass surgery was 2032.6 months. Coronary bypass surgery on-pump was performed in 88.3%, coronary bypass surgery on off-pump in 11.7%. The number of distal anastomoses ranged from 1 to 4. There were no differences in clinical and angiographic indicators, pharmacotherapy, and operation characteristics between the groups of patients who were subjected to or did not have PCI before coronary bypass surgery. There were no differences between the analyzed groups of patients in the frequency of cardiac death (0 and 1.1%, p=0.58), non-fatal MI (3.6% and 9.8%, p=0.29), stroke (0 and 1.1%, p=0.58), acute heart failure (11.7% and 34.8%, p=0.06), the number of patients with paroxysms of atrial fibrillation (28.6% and 17.4%, p=0.94), the proportion of patients with resternotomies (3.6% and 3.3%, p=0.94) and gastrointestinal bleeding (3.6% and 4.3%, p=0.86). PCI with coronary artery stenting, prior to coronary bypass surgery, does not affect the frequency of post-operative hospital cardiovascular and hemorrhagic complications.

The plasma proteome of rheumatic patients reveals differences in fingerprint based on the cardiovascular history

Background and Aims : The risk of cardiovascular diseases in patients with a rheumatic background is much higher compared to the normal population. Still, it’s etiology is not fully understood. In this study the plasma proteome of patients with a rheumatic background were compared with a group of patients who on top of their rheumatic background suffered from a cardiovascular event (CVE).Methods: The cohort consisted of a rheumatic patient control group (n=10) and a patient group (n=10) with a CVE history. Samples were collected 1 year prior to the CVE and 3-6 months after the CVE. Patients were matched with controls based on age, sex and medication use. Depletion of high abundant plasma proteins (TOP-14) was followed by “bottom up” shotgun proteomics using LC-MS/MS. Rstudio was used for normalization assessment and the relative changes in protein/peptide abundance were investigated using Perseus for comparison between the groups.Results: Principle component analysis (PCA) demonstrated a difference in overall protein and peptide signature between the control group and the CVE group. A total of 282 proteins determined this potential difference. Within the CVE group PCA revealed a more comparable signature before and after the CVE. Nevertheless, still 59 proteins demonstrated significant difference in relative abundancy within the CVE group.Conclusions: Here we demonstrated the existence of potential differences in the plasma proteome of rheumatic patient’s who suffered from a CVE. This signature may already exist prior to a CVE. This gives rise to further investigation of potential risk markers which may predict a relative risk for a CVE in rheumatic diseases.

Results of specialized outpatient follow-up of patients with embolic stroke of undetermined source

Background. The article considers with the current problem of cryptogenic stroke and embolic stroke of undetermined source.The objective was to analyzed the results of follow-up of patients with embolic stroke of undetermined source in a specialized outpatient center.Methods and materials. The data of 169 patients who completed a two-year follow-up period with embolic stroke of undetermined source (ESUS) and cardioembolic stroke were analyzed.Results. We presented comparative results on the structure of incidence rate, age differences, comorbid pathology, as well as on the frequency of repeated cardiovascular events in groups with cardioembolic stroke and embolic stroke of undetermined source.Conclusions. Patients with ESUS are an extremely difficult category of patients for diagnostic search, for whom the actual task is to develop an examination algorithm for the earliest possible detection of the cause of stroke and to determine the optimal methods of secondary prevention.

Age-stratified and blood-pressure-stratified effects of blood-pressure-lowering pharmacotherapy for the prevention of cardiovascular disease and death: an individual participant-level data meta-analysis

SummaryBackgroundThe effects of pharmacological blood-pressure-lowering on cardiovascular outcomes in individuals aged 70 years and older, particularly when blood pressure is not substantially increased, is uncertain. We compared the effects of blood-pressure-lowering treatment on the risk of major cardiovascular events in groups of patients stratified by age and blood pressure at baseline.MethodsWe did a meta-analysis using individual participant-level data from randomised controlled trials of pharmacological blood-pressure-lowering versus placebo or other classes of blood-pressure-lowering medications, or between more versus less intensive treatment strategies, which had at least 1000 persons-years of follow-up in each treatment group. Participants with previous history of heart failure were excluded. Data were obtained from the Blood Pressure Lowering Treatment Triallists' Collaboration. We pooled the data and categorised participants into baseline age groups (<55 years, 55–64 years, 65–74 years, 75–84 years, and ≥85 years) and blood pressure categories (in 10 mm Hg increments from <120 mm Hg to ≥170 mm Hg systolic blood pressure and from <70 mm Hg to ≥110 mm Hg diastolic). We used a fixed effects one-stage approach and applied Cox proportional hazard models, stratified by trial, to analyse the data. The primary outcome was defined as either a composite of fatal or non-fatal stroke, fatal or non-fatal myocardial infarction or ischaemic heart disease, or heart failure causing death or requiring hospital admission.FindingsWe included data from 358 707 participants from 51 randomised clinical trials. The age of participants at randomisation ranged from 21 years to 105 years (median 65 years [IQR 59–75]), with 42 960 (12·0%) participants younger than 55 years, 128 437 (35·8%) aged 55–64 years, 128 506 (35·8%) 65–74 years, 54 016 (15·1%) 75–84 years, and 4788 (1·3%) 85 years and older. The hazard ratios for the risk of major cardiovascular events per 5 mm Hg reduction in systolic blood pressure for each age group were 0·82 (95% CI 0·76–0·88) in individuals younger than 55 years, 0·91 (0·88–0·95) in those aged 55–64 years, 0·91 (0·88–0·95) in those aged 65–74 years, 0·91 (0·87–0·96) in those aged 75–84 years, and 0·99 (0·87–1·12) in those aged 85 years and older (adjusted pinteraction=0·050). Similar patterns of proportional risk reductions were observed for a 3 mm Hg reduction in diastolic blood pressure. Absolute risk reductions for major cardiovascular events varied by age and were larger in older groups (adjusted pinteraction=0·024). We did not find evidence for any clinically meaningful heterogeneity of relative treatment effects across different baseline blood pressure categories in any age group.InterpretationPharmacological blood pressure reduction is effective into old age, with no evidence that relative risk reductions for prevention of major cardiovascular events vary by systolic or diastolic blood pressure levels at randomisation, down to less than 120/70 mm Hg. Pharmacological blood pressure reduction should, therefore, be considered an important treatment option regardless of age, with the removal of age-related blood-pressure thresholds from international guidelines.FundingBritish Heart Foundation, National Institute of Health Research Oxford Biomedical Research Centre, Oxford Martin School.

Cardiovascular Complications and its Impact on outcomes in COVID-19: An Original Research.

Introduction:The viral infection COVID-19 is highly infectious and has claimed many lives till date and is still continuing to consume lives. In the COVID-19, along with pulmonary symptoms, cardiovascular (CV) events were also recorded that have known to significantly contribute to the mortality. In our study, we designed and validated a new risk score that can predict CV events, and also evaluated the effect of these complications on the prognosis in COVID-19 patients.Materials and Methods:A retrospective, multicenter, observational study was done among 1000 laboratory-confirmed COVID-19 patients between June 2020 and December 2020. All the data of the clinical and laboratory parameters were collected. Patients were randomly divided into two groups for testing and validating the hypothesis. The identification of the independent risk factors was done by the logistic regression analysis method.Results:Of all the types of the clinical and laboratory parameters, ten “independent risk factors” were identified associated with CV events in Group A: male gender, older age, chronic heart disease, cough, lymphocyte count <1.1 × 109/L at admission, blood urea nitrogen >7 mmol/L at admission, estimated glomerular filtration rate <90 ml/min/1.73 m2 at admission, activated partial thromboplastin time >37 S, D-dimer, and procalcitonin >0.5 mg/L. In our study, we found that CV events were significantly related with inferior prognosis (P < 0.001).Conclusions:A new risk scoring system was designed in our study, which may be used as a predictive tool for CV complications among the patients with COVID-19 infection.

Impact of daily glucose fluctuations on cardiovascular outcomes after percutaneous coronary intervention for patients with stable coronary artery disease undergoing lipid-lowering therapy.

Aims/IntroductionGlucose fluctuation (GF) is a residual risk factor for coronary artery disease (CAD). We investigated whether GF influenced clinical outcomes and progression of coronary stenosis in stable CAD patients.Materials and MethodsIn this prospective study, 101 consecutive lipid‐controlled stable CAD patients underwent percutaneous coronary intervention were enrolled, and GF was expressed as the mean amplitude of glycemic excursion (MAGE) obtained by continuous glucose monitoring before the procedure was evaluated. At 9 months after enrollment, culprit and non‐culprit (mild‐to‐moderate stenosis without ischemia) lesions were serially assessed by angiography. Cardiovascular events (CVE) consisting of cardiovascular death, non‐fatal myocardial infarction or ischemia‐driven revascularization during 2‐year follow up, rapid progression in non‐culprit lesions (defined as ≥10% luminal narrowing progression in lesions with stenosis ≥50%, ≥30% luminal narrowing progression in non‐culprit lesions with stenosis <50% or normal segment, or progression to total occlusion) were evaluated.ResultsCVE occurred in 25 patients, and MAGE was significantly higher in the CVE group (76.1 ± 24.8 mg/dL vs 59.3 ± 23.7 mg/dL; P = 0.003). Multivariate analysis showed that MAGE was an independent predictor of CVE (odds ratio 1.027, 95% confidence interval 1.008–1.047; P = 0.005). The optimal MAGE value to predict CVE was 70.7 mg/dL (area under the curve 0.687, 95% confidence interval 0.572–0.802; P = 0.005). Furthermore, MAGE was independently associated with rapid progression, and with the luminal narrowing progression in all non‐culprit lesions (r = 0.400, P < 0.05).ConclusionsDaily GF might influence future CVE in lipid‐controlled stable CAD patients.

Predictors of acute cardiovascular events following acute exacerbation period for patients with COPD: a nested case\u2013control study

BackgroundIt has been noted that there is an increase in the incidence of acute cardiovascular events (CVEs) in patients with chronic obstructive pulmonary disease (COPD) during an acute exacerbation (AE), thereby causing increased inpatient mortality. Thus, we have tried to identify predictors of acute CVEs in patients with AECOPD via a nested case–control study.MethodsA total of 496 cases hospitalized for AECOPD were included in this study, and followed-up for up to 6 months after discharge. Acute CVEs in the AE period were defined as a new or worsening acute coronary syndrome (ACS), arrhythmia, or left ventricular disfunction (LVD). Predictors of CVEs were selected from several variables, including baseline characteristics and treatments in the stable period as well as symptoms, laboratory tests, complications and treatments in the AE period.ResultsThirty cases (6.05%) had acute CVEs, namely 2 had ACS, 13 had LVD and 19 experienced some form of arrhythmia. Four deaths were observed in the CVE group, with significantly increased death risk compared with the non-CVE group (P = 0.001, OR = 5.81). Moreover, patients who had CVEs were more prone to have re-exacerbation within 3 months. Multivariate analysis showed that previous LVD history (P = 0.004, OR = 5.06), 20% increase in heart rate (HR) (P = 0.003, OR = 10.19), electrolyte disturbance (P = 0.01, OR = 4.24) and diuretics (P = 0.002, OR = 6.37) were independent predictors of CVEs. In addition, usage of theophylline, fluoroquinolone and inhaled beta agonists in the AE period were not statistically associated with acute CVEs.ConclusionsOur preliminary study indicates that patients hospitalized for AECOPD with previous LVD history or increased HR need close observation and diuretics should be cautiously used with regular electrolyte monitoring. These findings need to be confirmed in a large cohort.

Trabecular bone score may indicate chronic kidney disease-mineral and bone disorder (CKD-MBD) phenotypes in hemodialysis patients: a prospective observational study

BackgroundIn the general population, the trabecular bone score (TBS) represents the bone microarchitecture and predicts fracture risk independent of bone mineral density (BMD). A few studies reported that TBS is significantly reduced in dialysis patients. Chronic kidney disease-mineral and bone disorder (CKD-MBD) are accompanied by increased fracture risk, cardiovascular morbidity, and mortality. We investigated whether TBS is associated with comorbidity related to CKD-MBD or frailty in hemodialysis patients.MethodsIn this prospective observational study, TBS was obtained using the TBS iNsight software program (Med-Imaps) with BMD dual energy x-ray absorptiometry (DXA) images (L1–L4) from prevalent hemodialysis patients. A Tilburg frailty indicator was used to evaluate frailty, and hand grip strength and bio-impedance (InBody) were measured. A patient-generated subjective global assessment (PG-SGA) was used for nutritional assessment. The history of cardiovascular events (CVE) and demographic, clinical, laboratory, and biomarker data were collated. We then followed up patients for the occurrence of CKD-MBD related complications.ResultsWe enrolled 57 patients in total. The mean age was 56.8 ± 15.9 years (50.9% female). Prevalence of Diabetes mellitus (DM) was 40.4% and CVE was 36.8%. Mean TBS was 1.44 ± 0.10. TBS significantly reduced in the CVE group (1.38 ± 0.08 vs. 1.48 ± 0.10, p < 0.001). Multivariable regression analysis was conducted adjusting for age, sex, dialysis vintage, DM, CVE, albumin, intact parathyroid hormone, fibroblast growth factor 23, handgrip strength, and phosphate binder dose. Age (ß = − 0.030; p = 0.001) and CVE (ß = − 0.055; p = 0.024) were significant predictors of TBS. During the follow up period after TBS measurements (about 20 months), four deaths, seven incident fractures, and six new onset CVE were recorded. Lower TBS was associated with mortality (p = 0.049) or new onset fracture (p = 0.007, by log-rank test).ConclusionLower TBS was independently associated with increased age and CVE prevalence in hemodialysis patients. Mortality and fracture incidence were significantly higher in patients with lower TBS values. These findings suggest that TBS may indicate a phenotype of frailty and also a CKD-MBD phenotype reciprocal to CVE.

Incidence and risk factors for cardiovascular events in patients hospitalized with community-acquired pneumonia

Objective: To explore the incidence, risk factors of cardiovascular events (CVE) and their impact on 30-day mortality in patients hospitalized with community-acquired pneumonia (CAP). Methods: This is a multicenter, retrospective study. Patients hospitalized with CAP from 5 teaching hospitals in Beijing, Shandong and Yunnan provinces during 1 January 2013 to 31 December 2015 were included and clinical data were retrieved from the Hospital Information System (HIS), and patients were divided into CVE group and non-CVE group. Age, sex, comorbidities, pneumonia severity index(PSI)/CURB-65 score, routine blood test, biochemical examinations, radiological findings on admission and mortality on 30-day after admission were analyzed. The primary endpoint was acute CVE during hospitalization, the secondary endpoint was 30-day death after admission. Multivariate Cox regression analysis was used to explore the risk factors for CVE. Kaplan-Meier survival curve was used to compare the difference on 30-day mortality between CVE patients and non-CVE patients by Log-rank test. Multivariate Cox regression model was used to assess the impact of CVE on the 30-day mortality among CAP patients after adjustment with age, sex, comorbidities, PSI/CURB-65 score. Results: A total of 3 561 CAP patients were included into the final analysis, including 210 (5.9%) patients in CVE group and 3 351 (94.1%) patients in non-CVE group. Compared with patients in non-CVE group, patients in CVE group were older (P<0.001), prevalence of hypertension, coronary heart disease, chronic heart failure, cerebrovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, aspiration risk and bedrid were significantly higher (all P<0.001); prevalence of CURB-65 score 3-5 and PSI risk class Ⅳ/Ⅴ were also significantly higher (both P<0.001). The proportion of axillary temperature<36 ℃, respiratory rate≥30 beats/minutes, confusion, leukocytes>10×10(9)/L, hemoglobin<100 g/L, platelets>300×10(9)/L, albumin<35 g/L, blood urea nitrogen>7 mmol/L, fasting blood glucose>11 mmol/L, serum C-reaction protein>100 mg/L, serum procalcitonin≥2 μg/L, arterial pH<7.35, arterial PO(2)/FiO(2)≤300 mmHg (1 mmHg=0.133 kPa), and multilobar infiltrates and pleural effusion on chest X-ray or CT scan were significantly higher in CVE group than in non-CVE group(all P<0.05); the 30-day mortality was significantly higher in CVE group than in non-CVE group(P<0.001). The incidence of CVE was significantly higher in patients with cardiovascular and cerebrovascular disease(CVD) than in patients without CVD (13.9%(150/1 079) vs. 2.4%(60/2 482), χ(2)=178.737, P<0.001). Meanwhile, the incidence of CVE increased with PSI in patients with Ⅰ/Ⅱ, Ⅲ and Ⅳ/Ⅴ class, respectively(χ(2)=228.350, P<0.001); and CURB-65 score 0-1, 2 and 3-5, respectively (χ(2)=387.154, P<0.001). Cox regression analysis revealed that age (HR=1.05, 95%CI 1.02-1.09, P=0.002), coronary heart disease (HR=1.88, 95%CI 1.01-3.51, P=0.048), chronic heart failure (HR=4.25, 95%CI 1.89-9.52, P<0.001), PSI risk class (HR=1.66, 95%CI 1.50-2.62, P=0.029) and serum procalcitonin≥ 2 μg/L (HR=3.72, 95%CI 1.60-8.66, P=0.002) were independent risk factors for CVE in CAP patients. Kaplan-Meier curve showed that the survival probability of patients with CVE was significantly lower than patients without CVE (P<0.001). After adjustment for age, sex, comorbidities and PSI/CURB-65 score, Cox regression model showed that CVE was associated with increased 30-day mortality in CAP patients (HR=6.05, 95%CI 3.11-11.76, P<0.001). Conclusions: Although the incidence of CVE is not high in Chinese patients hospitalized with CAP, CVE is common in patients with severe pneumonia and in patients with CVD. Age, cardiovascular disease, PSI risk class and serum procalcitonin are the risk factors for CVE in this patient cohort. CVE is related to increased 30-day mortality in CAP patients.

Progressive Elevation of NT-ProBNP During Chemotherapy Is Related to Asymptomatic Cardiovascular Events in Patients With Multiple Myeloma

BackgroundPatients with multiple myeloma (MM) are at risk of cardiovascular events (CVEs) as a result of disease burden– and treatment-related risk factors. Cardiac biomarkers have been reported to be more sensitive than left ventricular ejection fraction in detecting CVEs. We sought to explore CVEs risk factors in MM patients and to establish sensitive predictors of biomarkers. Patients and MethodsWe studied 116 newly diagnosed MM patients who received chemotherapy in our department. Echocardiograms were examined at baseline and after 4 cycles of treatment, as well as upon clinical suspicion of a cardiac event or after an adjustment of treatment regimens. Cardiac biomarkers, including troponin T, myohemoglobin, and N terminal pro B-type natriuretic peptide (NT-proBNP), were estimated before each cycle and within 24 hours after chemotherapy, which was provided for at least 4 cycles. ResultsThirteen patients (11.2%) experienced CVEs, seven of which were subclinical. There was no significant difference between the CVE group and the non-CVE group in terms of general patient characteristics, MM disease factors, or chemotherapy drugs. The baseline levels of left ventricular ejection fraction and NT-proBNP were comparable between the 2 groups. NT-proBNP levels increased rapidly after chemotherapy and fell to normal levels before administration of the next cycle in all patients (60 pg/mL vs. 446 pg/mL, P < .001). Patients with asymptomatic CVEs showed a significantly higher proportion of progressively elevated NT-proBNP compared to symptomatic CVE and non-CVE patients (57% vs. 0 vs. 6.1%, P = .035). ConclusionThe dynamic change in NT-proBNP may predict early asymptomatic cardiac damage and allow interventional strategies to avoid cardiac decompensation.

Cost Implications of Anticoagulation Strategies After Percutaneous Coronary Intervention Among Patients With Atrial Fibrillation (A PIONEER-AF PCI Analysis)

The PIONEER AF-PCI trial demonstrated that in atrial fibrillation patients who underwent intracoronary stenting, either rivaroxaban 15 mg daily plus P2Y12 inhibitor monotherapy (Group 1) or 2.5 mg rivaroxaban twice daily plus dual antiplatelet therapy (DAPT) (Group 2) was associated with fewer recurrent hospitalizations, primarily for bleeding and cardiovascular events, compared with standard-of-care vitamin K antagonist and DAPT (Group 3). Associated costs are unknown. This study estimates costs associated with rivaroxaban strategies compared with vitamin K antagonist and DAPT. Medication costs were estimated using wholesale acquisition costs, medication discontinuation rates, and costs of monitoring. Using a large US healthcare claims database, the mean adjusted increase in 1-year cost of care for individuals with atrial fibrillation and percutaneous coronary intervention (PCI) rehospitalized for bleeding, cardiovascular, and other events was compared with those not rehospitalized. Using adjudicated rehospitalization rates from PIONEER AF-PCI, cost differences were estimated. Rates of rehospitalization for bleeding were 6.5%, 5.4%, 10.5%, and 20.3%, 20.3%, 28.4% for cardiovascular events in Groups 1, 2, and 3. Medication and monitoring costs were $3,942, $4,115, and $1,703. One-year costs for all recurrent hospitalization costs and/or patient for the groups were $24,535, $20,205, and $29,756. One-year cost increase associated with bleeding rehospitalizations and/or patient was $4,160, $3,212, and $6,876 and was $13,264, $11,545, and $17,220 for cardiovascular rehospitalizations and/or patient. Overall estimated cost per patient was $28,476, $24,320, and $31,458. Compared with warfarin, both rivaroxaban treatment strategies had higher medication costs, but these were more than accounted for by fewer hospitalizations.

Red cell distribution width and homocysteine act as independent risk factors for cardiovascular events in newly diagnostic essential hypertension.

Hyperhomocysteinemia and increased red cell distribution width (RDW) are associated with a higher possibility of adverse clinical outcomes of hypertension. The study aims to validate the effect of homocysteine (Hcy) and RDW on cardiovascular events (CVE) and investigate whether RDW is independently associated with serum Hcy in patients with essential hypertension (EH). The study reviewed 804 patients with newly diagnosed EH in our hospital. The clinical characteristics and laboratory results of all subjects were grouped according to the presence/absence of CVE. Patients in the CVE group had higher RDW and Hcy, as compared to the patients in the no CVE group. Multiple Cox regression analysis demonstrated that both RDW (HR = 1.24, 95% CI =1.02–1.56, P = 0.002) and Hcy (HR = 1.37, 95% CI = 1.02–1.80, P < 0.001) resulted significantly related to the CVE. Subsequent analysis found that patients with high RDW had higher Hcy levels as compared with those with low RDW (P = 0.007). Although Pearson's correlation suggested that RDW was positively correlated with Hcy (r = 0.122, P = 0.028), no significant correlation was observed between RDW and Hcy (β = 0.15, p = 0.126) after adjusted for a series of potential confounders using multiple linear regression analysis. In conclusion, RDW is not correlated with Hcy in patients with EH. Both RDW and Hcy are independent risk factors for CVE in newly diagnostic EH and have the potential to improve risk stratification.

Mean Platelet Volumes in Non-Alcoholic Fatty Liver Disease (NAFLD): Relationship to Cardiovascular Events

1.1.Background: Mean platelet volume (MPV) is a biomarker of platelet activity and elevations in MPV have been observed in the setting of acute cardiovascular events. The role of MPV in nonalcoholic fatty liver disease (NAFLD) is unclear at this time. 1.2. Aims:The aim of this study is to assess whether increases in MPV during acute cardiovascular events (CE) are observed in patients with NAFLD. 1.3.Methods:A retrospective case control study of 104 NAFLD patients with cardiovascular events (CE) matched to 104 NAFLD patients without cardiovascular events (non-CE) was performed. Demographics, cardiovascular risk factors, types of CE, laboratory data including MPV at the time of NAFLD diagnosis, and at the time of the CE as well as medications were collected. 1.4.Results:The mean age was 56 ± 8 years (yr) with a majority of white ethnicity (CE, n= 85 versus non-CE, n=76), an average body mass index (BMI) of 31.8 ± 5.1 and little to no fibrosis as based on the APRI (0.34 ± 0.19 in CE and 0.36 ± 0.17 in non-CE group, p= 0.47). The CE group had higher cardiovascular risk calculated by the Framingham Risk Score (FRS) (24 ± 11.6%) compared to the non-CE group (18 ±12%) (p=0.0002). Importantly, the absolute changes of MPV from the time of NAFLD diagnosis (T0)to the time of the cardiovascular event (TCE) [(MPV TCE -MPVT0) were statistically higher in the CE group than in the non-CE group. Conclusion:The absolute change in the MPV level at the time of the CV event was higher in the CE group compared to the non-CE group.MPV may be a convenient marker of increased cardiovascular risk in the NAFLD population.

Effects of Cardiovascular Events on End-Stage Renal Disease and Mortality in Patients With Chronic Kidney Disease Before Dialysis.

Cardiovascular events (CVEs) are major complications in patients with chronic kidney disease (CKD). However, few studies have investigated the effects of CVEs on end-stage renal disease (ESRD) and mortality of pre-dialysis patients. We followed 377 CKD patients who were at stage ≥G3 at first clinic visit in the Shuuwa General Hospital between April 2005 and July 2014. After taking baseline patient data, we evaluated renal survival rates and all-cause and CVE-related mortality in patients with CVEs [(+)CVEs] and without CVEs [(-)CVEs]. A total of 99 CVEs occurred in 93 study patients (57.0% cardiac events, 43.0% cerebrovascular events, and 6.5% peripheral artery disease events). During the study period, 127 patients reached ESRD over a median of 4.51 years' follow-up. Kaplan-Meier analysis found longer renal survival rates in the (-)CVEs group compared with the (+)CVEs group. Forty patients died during the study period over a median of 5.43 years' follow-up. Survival rates for all-cause and CVE-related mortality of (-)CVEs patients were higher than in (+)CVEs patients. After adjustment for sex, age, current smoking, blood pressure, diabetes, estimated glomerular filtration rate, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, left ventricular hypertrophy, body mass index, albumin, hemoglobin, calcium, phosphate, C-reactive protein, and spot urine protein, the occurrence of CVEs was still a significant risk factor for ESRD (HR 1.516, P = 0.017) and all-cause mortality (HR 7.871, P < 0.001). Our findings suggest that the occurrence of CVEs is a potent risk factor for ESRD and mortality in CKD patients before dialysis.

Impact of coronary artery anatomy on clinical course and prognosis in apical hypertrophic cardiomyopathy: analysis of coronary angiography and computed tomography.

Background and ObjectivesApical hypertrophic cardiomyopathy (AHCM) is an uncommon variant of hypertrophic cardiomyopathy with a relatively benign course. However, the prognostic factors of AHCM-particularly those associated with coronary artery disease (CAD) and its anatomical subtypes-are not well known.Subjects and MethodsWe enrolled 98 consecutive patients with AHCM who underwent coronary angiography or coronary computed tomography scanning at two general hospitals in Korea from January 2002 to March 2012. Patient charts were reviewed for information regarding cardiovascular (CV) risk factors, symptoms, and occurrence of CV events and/or mortality. We also reviewed echocardiographic data and angiography records.ResultsThe mean age at the time of enrollment was 61.45±9.78 years, with female patients comprising 38.6%. The proportions of mixed and pure types of AHCM were 34.4% and 65.6%, respectively. CAD was found in 31 (31.6%) patients. The mean follow-up period was 53.1±60.7 months. CV events occurred in 22.4% of patients, and the mortality rate was 5.1%. The mixed-type was more frequent in CV event group although this difference was not statistically significant (50% vs. 30%, p=0.097). The presence of CAD emerged as an independent risk factor for CV events in univariate and multivariate Cox regression analysis after adjusting for other CV risk factors.ConclusionCoronary artery disease is an independent risk factor for CV events in AHCM patients. However, AHCM without CAD has a benign natural course, comparable with the general population.

Relationship Between Oxidized LDL, IgM, and IgG Autoantibodies to ox-LDL Levels With Recurrent Cardiovascular Events in Swedish Patients With Previous Myocardial Infarction

We determined whether plasma levels of circulating oxidized low-density lipoprotein (LDL; E06), immunoglobulin (Ig) G, and IgM autoantibodies binding to malonyldialdehyde-modified LDL (MDA-LDL) may predict cardiovascular events (CVEs). Patients (n=123) with a previous myocardial infarction (MI) were included. The primary end point was defined as any of the following: cardiovascular death from any cause, nonfatal reinfarction or stroke, percutaneous coronary intervention, coronary artery bypass grafting, and hospitalization due to angina pectoris. There were 43 CVEs during the follow-up period of 8.4±3.5 years. There was no significant difference in the levels of E06 and MDA-LDL IgG between the CVE and the event-free group. However, MDA-LDL IgM levels were significantly lower in patients in the CVE group (9524±6326 relative light unit [RLU]) compared with the event-free (10,975±5398 RLU) group (P=.04). In conclusion, levels of MDA-LDL IgM were associated with an increased risk of CVE in patients with a previous MI.

ST-T Wave Abnormality in Lead aVR and Reclassification of Cardiovascular Risk (from the National Health and Nutrition Examination Survey-III)

Electrocardiographic lead aVR is often ignored in clinical practice. The aim of this study was to investigate whether ST-T wave amplitude in lead aVR predicts cardiovascular (CV) mortality and if this variable adds value to a traditional risk prediction model. A total of 7,928 participants enrolled in the National Health and Nutrition Examination Survey (NHANES) III with electrocardiographic data available were included. Each participant had 13.5 ± 3.8 years of follow-up. The study sample was stratified according to ST-segment amplitude and T-wave amplitude in lead aVR. ST-segment elevation (>8 μV) in lead aVR was predictive of CV mortality in the multivariate analysis when not accounting for T-wave amplitude. The finding lost significance after including T-wave amplitude in the model. A positive T wave in lead aVR (>0 mV) was the strongest multivariate predictor of CV mortality (hazard ratio 3.37, p <0.01). The addition of T-wave amplitude in lead aVR to the Framingham risk score led to a net reclassification improvement of 2.7% of subjects with CV events and 2.3% of subjects with no events (p <0.01). Furthermore, in the intermediate-risk category, 20.0% of the subjects in the CV event group and 9.1% of subjects in the no-event group were appropriately reclassified. The absolute integrated discrimination improvement was 0.012 (p <0.01), and the relative integrated discrimination improvement was 11%. In conclusion, T-wave amplitude in lead aVR independently predicts CV mortality in a cross-sectional United States population. Adding T-wave abnormalities in lead aVR to the Framingham risk score improves model discrimination and calibration with better reclassification of intermediate-risk subjects.

Evaluation of mortality, disease activity, treatment, clinical and immunological features of adult and late onset systemic Lupus erythematosus

Objectives: We retrospectively compared disease activity, treatment, clinical and laboratory features, and rate of mortality of 535 SLE patients with adult and late disease onset.Methods: patients were divided into two groups based on the onset of the disease before or after 50 years of age. Clinical data were collected from medical reports. Disease activity was measured by ECLAM score. Parameters were compared by χ2-test, Fisher’s test, Student’s t or the Mann–Whitney test.Results: Forty patients (7.5%) were included in the late SLE onset group (group A), while 495 (92.5%) in the adult SLE onset group (group B). Sicca symptoms were more frequent in group A (p < 0.0008), while glomerulonephritis (p < 0.0069), reduced C3 (p < 0.0006) and low C3 (p < 0.00002) and C4 levels (p < 0.0006) were more prevalent in group B. Twenty-two deaths (4.3%) were recorded: 14 (2.8%) in group B and 8 (20%) in group A. Deaths were mainly due to infections in group B (28.5%) and cardiovascular events in group A (50%). A lower use of HCQ and LDA were recorded in deceased versus living patients (p < 0.0001 and 0.0166, respectively), while a higher ECLAM score was measured at onset in dead versus living patients (p < 0.048).Conclusions: Late onset SLE occurred in 7.5% of patients and it was associated with sicca symptoms. The use of HCQ and LDA is positively correlated with survival. Death in late onset SLE occurred more frequently for cardiovascular involvement. Higher disease activity at onset of the disease might represent a poor prognostic factor for death in adult onset.
