BACKGROUND Patients with peripheral artery disease (PAD) are at high risk for major cardiovascular events (MACE), including myocardial infarction, stroke, and hospitalization for heart failure. We have previously shown the clinical efficacy of a 4th-generation synchronous telehealth program for some patients, but the costs and cardiovascular benefits of the program for PAD patients remain unknown. OBJECTIVE The telehealth program is now widely used by higher-risk cardiovascular patients to prevent further cardiovascular events. This study investigated whether patients with PAD would also have better cardiovascular outcomes after participating in the 4th-generation synchronous telehealth program. METHODS This was a retrospective cohort study. We screened 5062 patients with cardiovascular diseases who were treated at National Taiwan University Hospital and then enrolled 391 patients with the diagnosis of PAD. Of these patients, 162 took part in the telehealth program, while 229 did not and thus served as control patients. Inverse probability of treatment weighting (IPTW) based on the propensity score was used to mitigate possible selection bias. Follow-up outcomes included heart failure hospitalization (HFH), acute coronary syndrome (ACS), stroke, and all-cause readmission during the 1-year follow-up period and through the last follow-up. RESULTS The mean follow-up duration was 3.1 ± 1.8 years for the patients who participated in the telehealth program and 3.2 ± 1.8 years for the control group. The telehealth program patients exhibited lower risk of ischemic stroke than the control group in the first year after IPTW (0.9% vs. 3.5%; hazard ratio [HR] 0.24, 95% CI 0.07–0.80). The 1-year composite endpoint of vascular accident, including acute coronary syndrome and stroke, was also significantly lower in the telehealth program group after IPTW (2.4% vs. 5.2%; [HR] 0.46, 95% CI 0.21–0.997). At the end of the follow-up, the telehealth program group continued to exhibit a significantly lower rate of ischemic stroke than the control group after IPTW (0.9% vs. 3.5%; [HR] 0.52, 95% CI 0.28–0.93). Furthermore, the medical costs of the telehealth program patients were not higher than those of the control group, whether in terms of outpatient, emergency department, hospitalization, or total costs. CONCLUSIONS The PAD patients who participated in the 4th-generation synchronous telehealth program exhibited lower risk of ischemic stroke events over both mid- and long-term follow-up periods. However, larger scale and prospective randomized clinical trials are needed to confirm our findings.

Abstract Introduction Peripheral artery disease (PAD) is associated with heightened ischemic and bleeding risk in patients with acute coronary syndrome (ACS). With this study from real-life patients, we try to analyze the balance between ischemic and bleeding risk during treatment with dual antiplatelet therapy (DAPT) after an ACS according to the presence or not of PAD. Methods The data analyzed in this study were obtained from the fusion of 3 clinical registries of ACS patients: BleeMACS (2004–2013), CardioCHUVI/ARRITXACA (2010–2016) and RENAMI (2013–2016). All 3 registries include consecutive patients discharged after an ACS with DAPT and undergoing PCI. The merged data set contain 26,076 patients. A propensity-matched analysis was performed to match the baseline characteristics of patients with and without PAD. The impact of prior PAD in the ischemic and bleeding risk was assessed by a competitive risk analysis, using a Fine and Gray regression model, with death being the competitive event. For ischemic risk we have considered a new acute myocardial infarction (AMI), whereas for bleeding risk we have considered major bleeding (MB) defined as bleeding requiring hospital admission. Follow-up time was censored by DAPT suspension/withdrawal. Results From the 26,076 ACS patients, 1,600 have PAD (6.1%). Patients with PAD were older, and with more cardiovascular risk factors. DAPT with prasugrel/ticagrelor was less frequently prescribed in patients with PAD in comparison with the rest of the population (8.2% vs 22.8%, p<0.001). During a mean follow-up of 12.2±4.8 months, 964 patients died (3.7%), and 640 AMI (2.5%) and 685 MB (2.6%) were reported. After propensity-score matching, we obtained two matched groups of 1,591 patients. Patients with PAD showed a significant higher risk of both AMI (sHR 2.17, 95% CI 1.51–3.10, p<0.001) and MB (sHR 1.51, 95% CI 1.07–2.12, p=0.018), in comparison with those without PAD. The cumulative incidence of AMI was 63.9 and 29.8 per 1,000 patients/year in patients with and without PAD, respectively. The cumulative incidence of MB was 55.9 and 37.6 per 1,000 patients/year in patients with and without PAD, respectively. The rate difference per 1,000 patient-years for AMI between patients with and without PAD was +34.1 (95% CI 30.1–38.1), and for MB +18.3 (16.1–20.4). The net balance between ischemic and bleeding events comparing patients with and without PAD was positive (+15.8 per 1,000 patients/year, 95% CI 9.7–22.0). Conclusions PAD was associated with higher ischemic and bleeding risk after hospital discharge for ACS treated with DAPT. However, the balance between ischemic and bleeding risk was positive for patients with PAD in comparison with patients without PAD. As summary, ACS patients with PAD had an ischemic risk greater than the bleeding risk.

New Onset

Use of Cystatin C serum levels (CC) is a more sensible marker of renal function than serum Creatinine levels (Cr) and Glomerular Filtration Rate (GFR). Previous studies have shown that increased serum CC levels with normal GFR in a population with cardiovascular risks factors but without any cardiovascular disease is associated with increased cardiovascular events but this was not analyzed in ischemic heart disease patients. We prospectively studied 203 patients hospitalized with Acute Coronary Syndrome (ACS). Serum CC levels were determined in the first 24 hours of hospitalization in all cases and two groups were identified (>and< 0.95 mg/L). GFR was calculated by MDRD formulation using the first serum Cr determination in all patients and were established two groups (> and < 60 ml/min/1.73m2). Coronariography was performed in all patients. During 13 months follow-up period we analyzed Mayor Adverse Coronary Events (MACE) and Mortality. Patients with serum CC levels >0.95 were older, with higher hypertension prevalence, prior stroke, high frequency of renal disease and greater severity of coronary artery disease (42% patients with three-vessel coronary artery disease, p=0.05). During the follow-up these patients showed a significantly higher risk of heart failure new-onset (62% p=0.001) and mortality (14 %, p=0.001). Patients with GFR >60 and serum CC levels <0.95 presented significantly higher values of MACE (61%; p=0.001) and mortality (8%; p=0.001) in opposition to 18% and 3% respectively in the group of patients with GFR 3 60 and serum CC levels 30.95. Nevertheless significant prognostic differences between GFR >60 and serum CC levels <0.95 group and GFR >60 and serum CC levels >0.95 group were observed. In the multivariate analysis was observed than serum CC levels was an independent predictor to develop of new-onset heart failure (RR: 3.9 CI 95% 1.5–9.9; p=0.002), and mortality (RR: 2. CI 95% 1.2–3.6, p=0.001) during the follow-up. Serum CC levels are a powerful both mortality and heart failure predictor in patients with high risk ACS. High serum CC levels in patients with ACS and normal renal function identify a higher risk group. Serum CC determination may be include in the risk evaluation of patients with ACS.

Objective: To evaluate the association between peripheral artery disease (PAD) and major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS) in the Arabian Gulf. Methods: Data from 4,044 consecutive patients diagnosed with ACS admitted to 29 hospitals in four Arabian Gulf countries from January 2012 to January 2013 were analyzed. PAD was defined as any of the following: claudication, amputation for arterial vascular insufficiency, vascular reconstruction, bypass surgery, or percutaneous intervention in the extremities, documented aortic aneurysm or an ankle brachial index of <0.8 in any of the legs. MACE included stroke/transient ischemic attack (TIA), myocardial infarction (MI), all-cause mortality, and readmissions for cardiac reasons diagnosed between hospital admission and at 1-year post discharge. Analyses were performed using univariate and multivariate statistical techniques. Results: The overall mean age of the cohort was 60 ± 13 years and 66% (n = 2,686) were males. A total of 3.3% (n = 132) of the patients had PAD. Patients with PAD were more likely to be associated with smoking, prior MI, hypertension, diabetes mellitus, and stroke/TIA. At the 1-year follow-up, patients with PAD were significantly more likely to have MACE (adjusted OR [aOR], 2.07; 95% confidence interval [CI]: 1.41–3.06; p< 0.001). The higher rates of events were also observed across all MACE components; stroke/TIA (aOR, 3.22; 95% CI: 1.80–5.75; p< 0.001), MI (aOR, 2.15; 95% CI: 1.29–3.59; p =0.003), all-cause mortality (aOR, 2.21; 95% CI: 1.33–3.69; p =0.002), and readmissions for cardiac reasons (aOR, 1.83; 95% CI: 1.24–2.70; p =0.003). Conclusions: PAD was significantly associated with MACE in ACS patients in the Arabian Gulf.

Abstract Introduction Peripheral artery disease (PAD) and acute coronary syndrome (ACS) are two diseases with high morbidity and mortality and, sometimes, may be present simultaneously, making patient management more complex. Purpose This study sought to characterize and evaluate the prognostic impact of PAD in patients with an ACS. Methods This was a retrospective study of patients admitted with an ACS, periodically included in a national multicenter registry, between October 2010 and September 2019. Results Of a total of 26036 patients, 1429 had previous history of PAD. This group had a higher predominance of men (79,5% vs 72,0%, p&lt;0,001) and was older (71±11 years vs 66±14 years, p&lt;0,001). Besides having a higher burden of cardiovascular risk factors, they also had more past history of myocardial infarction (MI), stroke and chronic kidney disease. In patients with PAD, non-ST segment elevation MI was the most frequent type of MI (58,6% vs 45,0%, p&lt;0,001) and left ventricular ejection fraction assessed during hospitalization was lower (49±13% vs 51±12%, p&lt;0,001). These patients were submitted less frequently to a coronary angiography (74,0% vs 85,2%, p&lt;0,001) and, when performed, more cases of multivessel coronary artery disease were found (70,6% vs 50,4%, p&lt;0,001). Nevertheless, they were less likely to undergo revascularization, with fewer angioplasties performed (47,8% vs 64,7%, p&lt;0,001), despite the greater number of coronary artery bypass grafting (9,0% vs 6,0%, p&lt;0,001). Both during hospitalization and at discharge, ticagrelor, beta-blockers and ACE inhibitors were less prescribed in the PAD group. Statins prescription was also lower, but only at discharge. In a multivariate regression analysis, we found that, during hospitalization, the presence of PAD was associated with a significant higher risk of myocardial reinfarction (OR 1,90 (CI 1,18–3,06)) and death (OR 1,43 (CI 1,03–2,00)). In addition, there was a tendency for more strokes (OR 1,88 (CI 0,98–3,61)). During a 1-year follow-up, PAD was also independently associated with a significant increase in mortality (HR 1,50 (CI 1,16–1,95)). Conclusions PAD is a disease present in patients with a higher number of comorbidities and is associated with more severe coronary events. Nevertheless, these patients seem to receive less evidence-based therapy. In this study, PAD was independently associated with a significant increase in short and medium-term major adverse events.

Background The aim of our study was to evaluate whether treatments for peripheral artery disease changed in two different cohorts identified in 2002 and 2008, and whether this had an impact on mortality and major clinical outcomes after six years of follow-up. Methods Using administrative health databases of the largest region in Northern Italy, we identified patients admitted to hospital for peripheral artery disease in 2002 and 2008. Both cohorts were followed for six years. All cause death, acute coronary syndrome, stroke and major amputations, cardiovascular prevention drugs and revascularization procedures were collected. Incidence of events was plotted using adjusted cumulative incidence function estimates. The risk, for each outcome, was compared between 2002–2008 and 2008–2014 using a multivariable Fine and Gray’s semiparametric proportional subdistribution hazards model. Results In 2002 and 2008, 2885 and 2848 patients were identified. Adjusting for age, sex, Charlson comorbidity index and severity of peripheral artery disease we observed a significant reduction (in 2008 vs. 2002) in the risk of acute coronary syndrome (28%), stroke (27%) and major amputation (17%). No change was observed in the risk of death. The percentages of patients with peripheral artery revascularizations, during the hospital stay, increased: 43.8% in 2002 vs. 49.0% in 2008, p < 0.001. From 2002 to 2008 there was a significant absolute increase in the prescription of lipid-lowering drugs (+18%), antiplatelets (+7.2%) and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (+11.8%), p < 0.001. Conclusions In six years of follow-up we observed a reduction in risk of major cardiovascular events in 2008–2014 in comparison with the 2002–2008 cohort. Increasing use of revascularization interventions and cardiovascular prevention drugs could have contributed to the better prognosis.

AbstractEnhanced follow-up is needed to improve the results of secondary preventive care in patients with established cardiovascular disease. We examined the effect of long-term, nurse-based, secondary preventive follow-up by telephone on the recurrence of cardiovascular events. Open, randomised, controlled trial with two parallel groups. Between 1 January 2010 and 31 December 2014, consecutive patients (n = 1890) admitted to hospital due to stroke, transient ischaemic attack (TIA), or acute coronary syndrome (ACS) were included. Participants were randomised (1:1) to nurse-based telephone follow-up (intervention, n = 944) or usual care (control, n = 946) and followed until 31 December 2017. The primary endpoint was a composite of stroke, myocardial infarction, cardiac revascularisation, and cardiovascular death. The individual components of the primary endpoint, TIA, and all-cause mortality were analysed as secondary endpoints. The assessment of outcome events was blinded to study group assignment. After a mean follow-up of 4.5 years, 22.7% (n = 214) of patients in the intervention group and 27.1% (n = 256) in the control group reached the primary composite endpoint (HR 0.81, 95% CI 0.68–0.97; ARR 4.4%, 95% CI 0.5–8.3). Secondary endpoints did not differ significantly between groups. Nurse-based secondary preventive follow-up by telephone reduced the recurrence of cardiovascular events during long-term follow-up.

Abstract Background High plasma B-Type natriuretic peptide (BNP) level is associated with cardiac events or stroke in patients with atrial fibrillation (AF). However, it is still unknown whether BNP predicts worse clinical outcomes after catheter ablation ofAF. Purpose We aimed to see if plasma BNP level is associated with major adverse cardiac and cerebrovascular events (MACCE) after catheter ablation of AF. Methods We retrospectively analyzed 1,853 participants (73.1% men, mean age 63.3±10.3 years, 60.7% paroxysmal AF) who received first catheter ablation of AF with pre-ablation plasma BNP level measurement and completed follow-up more than 3 months after the procedure from AF Frontier Ablation Registry, a multicenter cohort study in Japan. We evaluated an association between plasma BNP level before catheter ablation and first MACCE in cox-regression hazard models adjusted for known risk factors. MACCE were defined as stroke/transient ischemic attack (TIA), cardiovascular events or all-cause death. Results The mean plasma BNP level was 120.2±3.7 pg/mL. During a mean follow-up period of 21.9 months, 57 patients (3.1%) suffered MACCE (ischemic stroke 8 [14.0%], hemorrhagic stroke 5 [8.8%], TIA 5 [8.8%], hospitalization for heart failure 11 [19.2%], acute coronary syndrome 9 [15.8%], hospitalization for other cardiovascular events 8 [14.0%] and all-cause death 11 [19.2%]). Plasma BNP level of patients with MACCE were significantly higher than those without MACCE (291.7±47.0 vs 114.7±3.42 pg/mL, P&lt;0.001). Multivariate analysis revealed that plasma BNP level (hazard ratio [HR] per 10 pg/mL increase 1.014; 95% confidence interval [CI] 1.005–1.023; P=0.001), baseline age (HR 1.052; 95% CI 1.022–1.084; P=0.001), heart failure (HR 2.698; 95% CI 1.512–4.815; P=0.001), old myocardial infarction (HR 3.593; 95% CI 1.675–7.708; P=0.001) and non-ischemic cardiomyopathy (HR 2.676; 95% CI 1.337 - 5.355; P=0.005) were independently associated with MACCE. At receiver-operating characteristic curve analysis, plasma BNP level before catheter ablation ≥162.7 pg/mL was the best threshold to predict MACCE (area under the curve: 0.71). Kaplan-Meier curve analysis (Figure) showed that the cumulative incidence of MACCE was significantly higher in patients with a BNP ≥162.7 pg/mL than in those with a BNP below 162.7 pg/mL (HR 4.85; 95% CI 2.86–8.21; P&lt;0.001). Conclusions Elevation of plasma BNP level was independently related to the increased risk of MACCE after catheter ablation ofAF. Funding Acknowledgement Type of funding source: Private company.

Background: Atrial fibrillation (AF) patients are likely to have concomitant coronary artery disease (CAD). A new strategy of antithrombotic therapy in AF patients with stable CAD was demonstrated in recent randomized clinical trials. Now that antithrombotic therapy for AF patients with CAD has reached a major turning point, it is important to know the prognostic factors in those patients. Purpose: In this study, we investigated clinical characteristics, cardiovascular events and prognostic factors in AF patients with CAD. Methods: The Fushimi AF Registry, a community-based prospective survey, was designed to enroll all of the AF patients who visited the participating medical institutions in Fushimi-ku, Kyoto, Japan. Follow up data including prescription status were available in 4,441 patients from March 2011 to November 2019. Of 4,441 patients, 645 patients had a history of CAD at enrollment. Results: The mean age was 76.4±8.6 and 65.9% were male. Averages of CHA 2 DS 2 -VASc score and HAS-BLED score were 4.41 and 2.35, respectively. Oral anticoagulant (OAC) was prescribed in 52.9% of those patients and antiplatelet drug (APD) was prescribed in 70.4%. The combination of OAC and APD was prescribed in 36.0%. During follow-up period (median 1,495 days), cardiac death occurred in 51 patients, composite of cardiac death, myocardial infarction (MI) and stroke in 136, and major bleeding in 77 (1.8, 5.1 and 2.9 per 100 person-years, respectively). In multivariate analysis, factors associated with composite of cardiac death, MI and stroke in AF patients with CAD were low body weight (<=50kg) (hazard ratio [95% confidence interval]; 1.62 [1.07-2.47]), previous stroke (1.69 [1.13-2.52]), heart failure (1.47 [1.02-2.11]), hypertension (0.60 [0.41-0.87]) and diabetes mellitus (1.62 [1.13-2.32]). Furthermore, factors associated with major bleeding in AF patients with CAD were anemia (male: hemoglobin<12 g/dl, female: hemoglobin<11 g/dl) (1.82 [1.09-3.04]) and thrombocytopenia (<150,000 /μL) (3.02 [1.29-7.03]). Conclusion: In Japanese AF patients with CAD, low body weight, previous stroke, heart failure, hypertension and diabetes mellitus were associated with cardiovascular events, and anemia and thrombocytopenia were associated with major bleeding.

Introduction: Thrombotic thrombocytopenic purpura (TTP) is a life-threatening clinical syndrome characterized by microangiopathy and a variable degree of end-organ ischemic damage. Cardiac involvement has been recognized as a major cause of mortality in these patients (Patschan et al, Nephrol Dial Transplant, 2006; Benhamou et al, J Thromb. Haemost, 2015). In this study, we aim to investigate clinical predictors and outcomes of acute coronary syndrome in the setting of TTP admissions. Methods: The National Inpatient Sample (NIS) was queried for all hospitalizations with a primary diagnosis of thrombotic microangiopathy (ICD- 9-CM code 4466 and ICD-10-CM code M3.11) from 2002 to 2017. Using ICD-9-CM procedure codes (9972), (9971), and (9979), as well as ICD-10-CM procedure codes (6A551Z3) and (6A550Z3) we identified patients who received plasma exchange (PLEX) during the same admission. Due to the wide spectrum of thrombotic microangiopathy diseases, we decided to include only those who received PLEX to get a more specific subpopulation who were presumed to have TTP. We stratified patients based on whether or not they had acute coronary syndrome (ACS) during the admission, defined as presence of any ICD code for either ST-segment elevation myocardial infarction (STEMI), Non-STEMI, or unstable angina. Baseline characteristics and inpatient outcomes were compared between groups. Statistical analysis was performed using SPSS v26 (IBM Corp, Armonk, NY, USA). The odds ratio (OR) and 95% confidence interval (CI) were calculated using the Cochran-Mantel-Haenszel test. A multivariate regression model was deployed to assess predictors of inpatient mortality. Complex weights were used throughout all calculations, enabling appropriate national projections. Results: A total of 15,640 patients with the diagnosis of thrombotic microangiopathy were identified during the studied period. Of those, 6,214 patients had received PLEX treatment during their admission (39.7%). The annual admission rate for TTP was ranging between 5-7/100,000 admissions. Patients had a mean age of 47.8 years; 67% were females, and 46.5% were Caucasian. Stratifying by geographic region, 24% were from the Northeast, 21% from the Midwest, 42% from the South, and 13% from the West. The most common primary payer was private insurance (42.7%). Overall inpatient mortality was 9.1%. The most common complications reported included acute kidney injury (42.5%), followed by acute respiratory failure (14.9%), incident dialysis (14.3%), acute encephalopathy (7.7%), acute heart failure (7.3%), acute cerebrovascular accident (7.2%), and acute coronary syndrome (6.3%). ACS was documented in 6.7% of patients. Compared with patients without ACS, those with ACS were relatively older and had a relatively higher prevalence of coronary artery disease, dyslipidemia, diabetes mellitus, essential hypertension, chronic kidney disease, and heart failure. Patients with ACS had a 3-fold higher in-hospital mortality and a longer mean hospital stay (19 days vs. 15 days, P&lt;0.001). Using stepwise logistic regression, we identified age (aOR 1.03; 95% CI, 1.02 - 1.03; P &lt;0.001), history of heart failure (aOR 2.02; 95% CI, 1.53-2.67; P &lt;0.001), and history of coronary artery disease (aOR 2.69; 95% CI, 2.03 - 3.57; P &lt;0.001) as independent predictors of ACS among patients hospitalized with TTP. On another regression analysis, certain complications were more prevalent in the ACS group including acute cerebrovascular accidents, acute heart failure, acute kidney injury, cardiogenic shock, and respiratory failure. Conclusion: Despite wider utilization of therapeutic plasmapheresis and improved supportive treatments for patients with TTP, associated morbidity and mortality remain significant. We demonstrate from this large retrospective cohort that ACS is an independent predictor of higher morbidity and mortality in TTP patients. We identified older age, history of heart failure, and history of coronary artery disease as independent predictors of ACS among patients admitted with TTP. Further studies are warranted to develop risk stratification models for patients with TTP.
