Comparison of guidelines for diagnosing suspected stable angina and the additional value of the calcium score. Int J Cardiol 2021; 344:1-7. [PMID: 34555447 DOI: 10.1016/j.ijcard.2021.09.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 07/05/2021] [Accepted: 09/17/2021] [Indexed: 11/24/2022]
Abstract
Background The performance of current diagnostic algorithms of the American College of Cardiology/American Heart Association (ACC/AHA), National Institute for Health and Care Excellence (NICE) and European Society of Cardiology (ESC) in patients with stable chest pain and coronary artery calcium (CAC) remains a matter of debate. We compared their merits in patients with CAC and investigated the additional value of the CAC score to improve diagnostic accuracy and risk stratification. Methods and results Patient data were obtained from a prospective registry of 642 consecutive patients. Mean age 63 (SD 11) years, 50% male. According to the guidelines, low and intermediate/high pre-test probability groups were constructed. Patients were reclassified based on their CAC score. Obstructive coronary artery disease (CAD) was observed in 14%. All models performed modestly in accurately predicting CAD (c-statistic <0.65). After addition of the CAC score, the c-statistic of the NICE model increased to 0.75 (95% confidence interval (CI) 0.73-0.78) which was just non-significant compared to the ESC model (0.71 95% CI 0.67-0.74) and performed significantly better than ACC/AHA (0.68 (95% CI 0.64-0.72)). After reclassification more than 50% of patients were classified low risk in NICE and ESC, while the prevalence of obstructive CAD (4.8% and 5.2% respectively) did not increase. Conclusions Addition of the CAC score to the studied models improved the ability to safely rule-out obstructive CAD and identified other patients at high risk for future coronary artery events. These results suggest that incorporating CAC score will lead to substantially less downstream testing and lower costs.

Two decades after coronary radiation therapy: A single center longitudinal clinical study. Catheter Cardiovasc Interv 2020; 96:E204-E212. [PMID: 31789481 PMCID: PMC7540400 DOI: 10.1002/ccd.28637] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Revised: 10/21/2019] [Accepted: 11/21/2019] [Indexed: 11/26/2022]
Abstract
Objectives The aim of this study was to evaluate the very long‐term clinical outcome after radioactive stent (RS) implantation and intracoronary β radiation brachytherapy (IRBT). Background Radioactive stents (RS) and intracoronary β radiation brachytherapy (IRBT) were introduced to prevent restenosis after percutaneous coronary intervention (PCI). Both techniques were associated with a higher incidence of major adverse cardiac events (MACE) in the short and intermediate‐term follow up as compared to conventional PCI. Methods One hundred and thirty‐three patients received radioactive stents (32P) and 301 patients were treated with IRBT adjunctive to PCI. These groups were propensity matched to respectively 266 and 602 control patients who were treated with routine PCI during the same inclusion period. Endpoints were all‐cause mortality and MACE, defined as all‐cause death, any myocardial infarction or any revascularization. Results Median follow‐up duration was 17 years. All‐cause mortality rates were similar in all groups. Adjusted hazard ratios for MACE and mortality in the RS cohort were 1.55 (95% CI 1.20–2.00) and 0.92 (95% CI 0.63–1.34), respectively. Adjusted hazard ratios for MACE and all‐cause mortality in the IRBT cohort were 1.41 (95% CI 1.18–1.67) and 0.95 (95% CI 0.74–1.21), respectively. The difference in MACE rates was predominantly driven by coronary revascularizations in both groups, with a higher MI rate in the IRBT group as well. Conclusions Coronary radiation therapy was associated with early increased MACE rates, but the difference in MACE rates decreased beyond 2 years, resulting in a comparable long‐term clinical outcome. Importantly, no excess in mortality was observed.

Stress-Only Adenosine CMR Improves Diagnostic Yield in Stable Symptomatic Patients With Coronary Artery Calcium. JACC Cardiovasc Imaging 2020; 13:1152-1160. [PMID: 31954641 DOI: 10.1016/j.jcmg.2019.12.009] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 11/27/2019] [Accepted: 12/05/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVES This study assessed whether adenosine stress-only perfusion cardiac magnetic resonance (CMR) following a positive coronary artery calcium (CAC) score improved the diagnostic yield of invasive coronary angiography (CAG) in patients with stable chest pain. The study also established the association between positive CAC scores and stress-induced myocardial ischemia. BACKGROUND The diagnostic yield of catheterization among patients with suspected coronary artery disease (CAD) is low. Improved patient selection and diagnostic testing are necessary. The CAC score can minimize unnecessary diagnostic testing, and in low-risk patients, normal CMR results have a high negative predictive value. Less comprehensive protocols may be sufficient to guide further work-up. METHODS A total of 642 consecutive patients (mean age: 63 years; 50% women) with stable chest pain and CAC scores of >0 who were referred for CMR were enrolled. Patients with a perfusion defect were subsequently examined by CAG. Patients were followed up for 1 year. Outcome was obstructive CAD. RESULTS Obstructive CAD was present in 12% of patients. For CAD diagnosis, the sensitivity of adenosine CMR was 90.9% (95% confidence interval [CI]: 88.7 to 93.1), specificity was 98.7% (95% CI: 97.9 to 99.6), positive predictive value was 92.0% (95% CI: 89.8 to 94.1), and negative predictive value was 98.6% (95% CI: 97.6 to 99.5). A CAC score between 0.1 and 100 without typical angina was associated with obstructive CAD in only 3% of patients. Patients with nonanginal chest pain and a CAC score ≥400 had obstructive CAD (16%). CONCLUSIONS Stress-only adenosine CMR had high diagnostic accuracy and served as an efficient gatekeeper to CAG in stable patients with a CAC score >0. Patients with CAC scores between 0.1 and 100 could be deferred from further testing in the absence of clinical features that suggested high risk. However, in patients with CAC score ≥400, functional testing should be indicated, regardless of the type of chest pain.

Life-long clinical outcome after the first myocardial revascularization procedures: 40-year follow-up after coronary artery bypass grafting and percutaneous coronary intervention in Rotterdam. Interact Cardiovasc Thorac Surg 2019; 28:852-859. [PMID: 30753554 DOI: 10.1093/icvts/ivz006] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Revised: 12/15/2018] [Accepted: 12/19/2018] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Our goal was to evaluate the outcomes of the first patients treated by venous coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCIs) with balloon angioplasty at a single centre who have reached up to 40 years of life-long follow-up. METHODS We analysed the outcomes of the first consecutive patients who underwent (venous) CABG (n = 1041) from 1971 to 1980 and PCI (n = 856) with balloon angioplasty between 1980 and 1985. Follow-up was successfully achieved in 98% of patients (median 39 years, range 36-46) who underwent CABG and in 97% (median 33 years, range 32-36) of patients who had PCI. RESULTS The median age was 53 years in the CABG cohort and 57 years in the PCI cohort. A total of 82% of patients in the CABG group and 37% of those in the PCI group had multivessel coronary artery disease. The cumulative survival rates at 10, 20, 30 and 40 years were 77%, 39%, 14% and 4% after CABG, respectively, and at 10, 20, 30 and 35 years after PCI were 78%, 47%, 21% and 12%, respectively. The estimated life expectancy after CABG was 18 and 17 years after the PCI procedures. Repeat revascularization was performed in 36% and 57% of the patients in the CABG and PCI cohorts, respectively. CONCLUSIONS This unique life-long follow-up analysis demonstrates that both CABG and PCI were excellent treatment options immediately after their introduction as the standard of care. These procedures were lifesaving, thereby indirectly enabling patients to be treated with newly developed methods and medical therapies during the follow-up years.

Abstract
BACKGROUND Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) is useful in the evaluation of cardiac allograft vasculopathy (CAV) in heart transplant (HTx) recipients. The current study evaluated the long-term prognostic value of stress SPECT MPI for predicting all-cause mortality and cardiac events in HTx recipients. METHODS The study population consisted of 166 HTx recipients (mean age 54 ± 10 years, 84% male) who underwent exercise or dobutamine stress 99mTc-tetrofosmin SPECT MPI for the assessment of CAV. An abnormal SPECT MPI was defined as the presence of a fixed or a reversible perfusion defect. Endpoints were all-cause mortality, cardiac mortality, and non-fatal myocardial infarction (MI). RESULTS MPI abnormalities were detected in 55 patients (33%), including fixed defects in 28 patients (17%), partially reversible in 17 patients (10%), and completely reversible defects in 10 patients (6%). During a median follow-up of 12.8 years (range 0-15, mean follow-up 9.5 years), 109 (66%) patients died (all-cause mortality), of which 67 (40%) were due to cardiac causes. A total of 5 (3%) patients experienced a non-fatal MI. HTx recipients with a normal stress 99mTc-tetrofosmin SPECT MPI had a significantly better prognosis as compared with those with an abnormal study, up to 5 years after the initial test. The presence of a reversible perfusion defect was a significant predictor of all-cause mortality, cardiac mortality, and major cardiac events, during the entire follow-up period. CONCLUSIONS Stress 99mTc-tetrofosmin SPECT MPI provides valuable prognostic information for the prediction of long-term outcome in HTx recipients. Patients with a normal stress 99mTc-tetrofosmin SPECT MPI have a significantly better prognosis as compared with those with an abnormal study, up to 5 years after initial testing.

Abstract
OBJECTIVE In this secondary analysis of data from the OPTICARE trial, we compared the effects of two behavioral interventions integrated into cardiac rehabilitation to standard rehabilitation with regard to functional capacity, fatigue, and participation in society. DESIGN This is a randomized controlled trial. SETTING This study was conducted in a cardiac rehabilitation setting. SUBJECTS A total of 740 patients with acute coronary syndrome were recruited for this study. INTERVENTIONS Patients were randomized to (1) three months of standard rehabilitation; (2) cardiac rehabilitation plus nine months after-care with face-to-face group lifestyle counseling; or (3) cardiac rehabilitation plus nine months after-care with individual lifestyle telephone counseling. MAIN MEASURES Functional capacity (6-minute walk test), fatigue (Fatigue Severity Scale), and participation in society (Utrecht Scale for Evaluation of Rehabilitation-Participation) were measured at randomization, 3, 12, and 18 months. RESULTS Additional face-to-face sessions resulted at 12 months in 12.49 m more on the 6-minute walk test compared to standard rehabilitation (P = .041). This difference was no longer present at 18 months. Prevalence of fatigue decreased from 30.2% at baseline to 11.9% at 18 months compared to an improvement from 37.3% to 24.9% after standard rehabilitation (between-group difference: odds ratio = 0.47; P = .010). The additional improvements in functional capacity seemed to be mediated by increases in daily physical activity. No mediating effects were found for fatigue. No additional improvements were seen for participation in society. Additional telephonic sessions did not result in additional intervention effects. CONCLUSION Extending cardiac rehabilitation with a face-to-face behavioral intervention resulted in additional long-term improvements in fatigue and small improvements in functional capacity up to 12 months. A telephonic behavioral intervention provided no additional benefits.

Abstract
Aims Currently, comparative data on procedural and long-term clinical outcome of outflow tract (OT) idiopathic ventricular arrhythmia (IVA) ablation with manual (MAN), contact force (CF), and magnetic navigation system (MNS) ablation are lacking. The aim of this study was to compare the procedural and long-term clinical outcome of MAN, CF, and MNS ablation of OT IVAs. Methods and results Seventy-three patients (31 MAN, 17 CF, and 25 MNS patients; consecutive per group) with OT IVA, who underwent catheter ablation in our centre were analysed. Procedural success rates (success at the end of the procedure), procedural data and long-term follow-up data were compared. Baseline patient demographics were comparable. Procedural success rates were similar (MAN 81%, 71% CF, and MNS 92%; P = 0.20). Median fluoroscopy time was shorter in the MNS group: MAN 29 (16-38), CF 37 (21-46), and MNS 13 (10-20) min (P = 0.002 for MNS vs. CF and MAN). The overall complication rate was: MAN 10%, CF 0%, and MNS 0% (P = 0.12). Median follow-up was: MAN 2184 (1672-2802), CF 1721 (1404-1913), and MNS 3031 (2524-3286) days (P <0.001). Recurrences occurred in MAN 46%, CF 50%, and MNS 46% (P = 0.97). Repeat procedures were performed in MAN 20%, CF 40%, and MNS 33% (P = 0.32). Conclusion Procedural and long-term clinical outcome of OT IVA ablation are equal for MAN, CF, and MNS. MNS has a favourable procedural safety profile due to the shorter fluoroscopy time compared with MAN and CF.

Abstract
Aims We aimed to assess the effects of a multidisciplinary cardiac rehabilitation (CR) program on survival after treatment with primary percutaneous coronary intervention (pPCI) for acute coronary syndrome (ACS). Methods and results Using propensity matching analysis, a total of 1159 patients undergoing CR were 1:1 matched with ACS patients who did not undergo CR and survived at least 60 days. The Kaplan-Meier analyses and multivariate Cox regression analysis were applied to study differences in survival. During follow-up, a total of 335 (14.5%) patients had died. Cumulative mortality rates at 5 and 10 years were 6.4% and 14.7% after CR and 10.4% and 23.5% in the no CR group (P < 0.001). Cardiac rehabilitation patients had 39% lower mortality than non-CR controls [10-year mortality 14.7% vs. 23.5%; adjusted hazard ratio (HR) 0.61; 95% confidence interval (CI) 0.46-0.81]. A total of 915 (78.9%) patients completed CR and had 46% lower mortality than those who did not complete CR (10-year mortality 13.6% vs. 18.9%; adjusted HR 0.54; 95% CI 0.42-0.70). Conclusion Patients who underwent pPCI for ACS, with a CR program had lower mortality than their non-CR counterparts. Mortality was particularly low in patients who completed the program. In conclusion, CR is still beneficial in terms of survival.

Abstract
BACKGROUND Standard cardiac rehabilitation (CR) is insufficient to help patients achieve an active lifestyle. The effects of two advanced and extended behavioral CR interventions on physical activity (PA) and sedentary behavior (SB) were assessed. METHODS In total, 731 patients with ACS were randomized to 1) 3months of standard CR (CR-only); 2) 3months of standard CR with three pedometer-based, face-to-face PA group counseling sessions followed by 9months of aftercare with three general lifestyle, face-to-face group counseling sessions (CR+F); or 3) 3months of standard CR, followed by 9months of aftercare with five to six general lifestyle, telephonic counseling sessions (CR+T). An accelerometer recorded PA and SB at randomization, 3months, 12months, and 18months. RESULTS The CR+F group did not improve their moderate-to-vigorous intensity PA (MVPA) or SB time compared to CR-only (between-group difference=0.24% MVPA, P=0.349; and 0.39% SB, P=0.529). However, step count (between-group difference=513 steps/day, P=0.021) and time in prolonged MVPA (OR=2.14, P=0.054) improved at 3months as compared to CR-only. The improvement in prolonged MVPA was maintained at 18months (OR=1.91, P=0.033). The CR+T group did not improve PA or SB compared to CR-only. CONCLUSIONS Adding three pedometer-based, face-to-face group PA counseling sessions to standard CR increased daily step count and time in prolonged MVPA. The latter persisted at 18months. A telephonic after-care program did not improve PA or SB. Although after-care should be optimized to improve long-term adherence, face-to-face group counseling with objective PA feedback should be added to standard CR.

Renal function and anemia in relation to short- and long-term prognosis of patients with acute heart failure in the period 1985-2008: A clinical cohort study. PLoS One 2018; 13:e0201714. [PMID: 30086179 PMCID: PMC6080795 DOI: 10.1371/journal.pone.0201714] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Accepted: 07/21/2018] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Renal dysfunction and anaemia are common in patients with acute heart failure (HF). It is not known whether their combined presence has additive prognostic value. We investigated their prognostic value separately and in combination, on prognosis in acute HF patients. Furthermore, we examined whether the improvement in prognosis was comparable between patients with and without renal dysfunction. METHODS AND RESULTS This prospective registry includes 1783 patients admitted to the (Intensive) Coronary Care Unit for acute HF in the period of 1985-2008. The outcome measure was the composite of all-cause mortality, heart transplantation and left ventricular assist device implantation. In patients without renal dysfunction, anemia was associated with worse 30-day outcome (HR 2.91; [95% CI 1.69-5.00]), but not with 10-year outcome (HR 1.13 [95% CI 0.93-1.37]). On the contrary, anemia was found to influence prognosis in patients with renal dysfunction, both at 30 days (HR 1.93 [95% CI 1.33-2.80]) and at 10 years (HR 1.27 [95% CI 1.10-1.47]). Over time, the 10-year survival rate improved in patients with preserved renal function (HR 0.73 [95% CI 0.55-0.97]), but not in patients with renal dysfunction. CONCLUSION The long-term prognosis of acute HF patients with a preserved renal function was found to have improved significantly. However, the prognosis of patients with renal dysfunction did not change. Anemia was a strong prognosticator for short-term outcome in all patients. In patients with renal dysfunction, anemia was also associated with impaired long-term prognosis.

Abstract
BACKGROUND It is not entirely clear whether ischemia burden on stress single-photon emission computed tomography (SPECT) effectively identifies patients who have a long-term benefit from coronary revascularization. METHODS The study population consisted of 719 patients with ischemia on stress SPECT. Early coronary revascularization was defined as percutaneous coronary intervention or coronary artery bypass grafting ≤90 days after SPECT. Patients who underwent late revascularization (>90 days after SPECT) were excluded (n = 164). RESULTS Of the 538 patients (73% men, mean age 59.8 ± 11 years), 348 patients had low ischemia burden (<3 ischemic segments) and 190 patients had moderate to high ischemia burden (≥3 ischemic segments). A total of 76 patients underwent early revascularization. During a median follow-up of 12 years (range 4-17), 283 patients died of whom 125 due to cardiac causes. Early revascularization was beneficial on all-cause mortality (HR 0.46, 95% CI 0.30-0.46) and cardiac mortality (HR 0.54, 95% CI 0.29-0.99). CONCLUSIONS Patients with myocardial ischemia on stress SPECT who underwent early revascularization had a lower all-cause mortality and cardiac mortality during long-term follow-up as compared to patients who received pharmacological therapy alone. This difference in long-term outcomes was mainly influenced by the survival benefit of early revascularization in the patients with moderate to high ischemia burden.

Cardiac stress imaging for the prediction of very long-term outcomes: Dobutamine stress echocardiography or dobutamine 99mTc-sestamibi SPECT? J Nucl Cardiol 2018; 25:471-479. [PMID: 27444501 PMCID: PMC5869882 DOI: 10.1007/s12350-016-0521-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Revised: 04/18/2016] [Indexed: 12/03/2022]
Abstract
BACKGROUND Both dobutamine stress echocardiography (DSE) and myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) are frequently used for cardiac risk stratification. The long-term relative prognostic value of these modalities has not been studied. Therefore, this study evaluated the long-term prognostic value of DSE compared to MPI in patients unable to perform exercise testing. METHODS This prospective, single center study included 301 patients (mean age 59 ± 12 years, 56% men) unable to perform exercise tests who underwent DSE and dobutamine stress 99mTc-sestamibi MPI. End points during follow-up were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction (MI). Univariable and multivariable Cox proportional hazards regression models were used to identify independent predictors of outcome. The probability of survival was calculated using the Kaplan-Meier method. RESULTS A total of 182 patients (60%) had an abnormal DSE and 198 (66%) patients had an abnormal MPI. The agreement between DSE and MPI was 82% (κ = 0.62). During a median follow-up of 14 years (range 5-18), 172 deaths (57%) occurred, of which 72 (24%) were due to cardiac causes. Nonfatal MI occurred in 46 patients (15%). The multivariable analysis demonstrated that an abnormal DSE was a significant predictor of cardiac mortality (HR 2.35, 95% CI [1.17-4.73]) and hard cardiac events (HR 2.11, 95% CI [1.25-3.57]). Also, an abnormal MPI result was a significant predictor of cardiac mortality (HR 3.03, 95% CI [1.33-6.95]) and hard cardiac events (HR 2.06, 95% CI [1.12-3.79]). CONCLUSIONS DSE and MPI are comparable in predicting long-term cardiac mortality and hard cardiac events in patients unable to perform exercise testing.

[PMID: 29374400 PMCID: PMC5845936 DOI: 10.1007/s40477-017-0277-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Accepted: 11/21/2017] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Hypertrophic cardiomyopathy (HC) is characterized by left ventricular (LV) hypertrophy and associated with papillary muscle (PM) abnormalities. The aim of this study was to evaluate the utility of three-dimensional echocardiography (3DE) for the geometric assessment of LV hypertrophy and PM morphology. METHODS The study included 24 patients with an established diagnosis of HC and 31 healthy controls. 3DE was performed using an iE33 or EPIQ 7C ultrasound system with an X5-1 transducer. QLAB software was used for the 3D analysis of LV wall thickness (LVWT) and PM morphology and hypertrophy; the number and cross-sectional area (CSA) of anterolateral and posteromedial PMs; and the presence of bifid or accessory PMs. RESULTS Patients with HC had a larger LVWT compared to controls in all segments (p < 0.001), and LVWT was largest in the midventricular septal segment (2.12 ± 0.68 cm). The maximum LVWT followed a spiral pattern from the LV base to the apex. The CSA of both anterolateral and posteromedial PMs was larger in patients with HC than in controls (1.92 vs. 1.15 cm2; p = 0.001 and 1.46 vs. 1.08 cm2; p = 0.033, respectively). The CSA of the posteromedial PM was larger in patients with LVOT obstruction than in those without (2.64 vs 1.16 cm2, p = 0.021). CONCLUSIONS 3DE allows the assessment of LV geometry and PM abnormalities in patients with HC. 3DE demonstrated that the maximum hypertrophy was variable and generally located in a spiral from the LV base to the apex.

NT-proBNP is associated with mortality and adverse cardiac events in patients with atrial fibrillation presenting to the emergency department. Clin Cardiol 2018; 41:400-405. [PMID: 29480582 DOI: 10.1002/clc.22883] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2017] [Revised: 12/22/2017] [Accepted: 12/27/2017] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia in the emergency department. The CHA2 DS2 -VASc score helps to predict thromboembolic risk; however, the rate of other adverse cardiac events is more difficult to predict. HYPOTHESIS The biomarker N-terminal pro-brain natriuretic peptide (NT-proBNP) has prognostic value in patients presenting to the emergency department with AF. METHODS During a 1.5-year period, a prospective study was performed in consecutive patients presenting to the emergency department with AF on the presenting electrocardiogram. At baseline, NT-proBNP was measured. The primary endpoints were all-cause death and major adverse cardiac events (MACE: all-cause mortality, myocardial infarction, or revascularization). RESULTS A total of 355 patients were included (mean age, 71 years; 55% male). The median duration of follow-up was 2 years. After adjustment for baseline variables, the logNT-proBNP was independently correlated with death (hazard ratio [HR]: 1.54, 95% confidence interval [CI]: 1.18-1.99) and MACE (HR: 1.27, 95% CI: 1.03-1.58). After adjustment for baseline variables, a high NT-proBNP value (>500 pmol/L) was independently correlated with death (HR: 2.26, 95% CI: 1.19-4.28), and for MACE a trend was seen (HR: 1.67, 95% CI: 0.96-2.91) compared with a low value (<250 pmol/L). CONCLUSIONS In patients presenting to the emergency department with AF, higher NT-proBNP values are independently associated with an increased mortality and MACE. Therefore, this biomarker may be a useful prognostic marker in the management and treatment of these patients.

Prediction of 14-year cardiovascular outcomes by dobutamine stress 99mTc-tetrofosmin myocardial perfusion SPECT in elderly patients unable to perform exercise testing. J Nucl Cardiol 2018; 25:63-71. [PMID: 27381341 DOI: 10.1007/s12350-016-0516-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2016] [Accepted: 04/08/2016] [Indexed: 11/25/2022]
Abstract
BACKGROUND Dobutamine stress myocardial perfusion imaging (MPI) is a useful alternative for the evaluation of coronary artery disease (CAD) in elderly patients who are unable to perform an exercise stress test. However, data on the long-term prognostic value of stress MPI in elderly patients are lacking. Therefore, this study evaluated the long-term prognostic value of dobutamine stress MPI in elderly patients unable to perform an exercise test. METHODS The study population consisted of 247 elderly patients (mean age 71 ± 5 years) who underwent dobutamine stress single-photon emission computed tomography (SPECT) MPI. An abnormal SPECT study was defined as the presence of fixed and/or reversible perfusion defects. A summed stress score (SSS) was obtained to estimate the extent and severity of perfusion defects. End points during follow-up were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction (MI). RESULTS During a median follow-up of 14 years (range 12-16), 168 (68%) patients died (all-cause mortality), of which 56 (23%) were due to cardiac causes. Nonfatal MI occurred in 19 (8%) patients. Kaplan-Meier survival curves showed that MPI provided optimal risk stratification in patients with normal and abnormal MPI. Multivariable analysis identified an abnormal MPI as a strong significant predictor of all-cause mortality and cardiac events. A multivariable analysis also revealed that a reversible defect and SSS were strong long-term predictors of cardiac mortality and hard cardiac events. CONCLUSION Dobutamine stress 99mTc-tetrofosmin SPECT provides incremental prognostic information for the prediction of long-term cardiovascular outcomes in elderly patients, unable to perform exercise testing. Dobutamine stress MPI is useful in risk classifying elderly patients.

Coupling interval variability of premature ventricular contractions in patients with different underlying pathology: an insight into the arrhythmia mechanism. J Interv Card Electrophysiol 2018; 51:25-33. [PMID: 29305677 PMCID: PMC5797566 DOI: 10.1007/s10840-017-0309-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Accepted: 12/19/2017] [Indexed: 11/26/2022]
Abstract
Purpose Coupling interval (CI) variability of premature ventricular contractions (PVCs) is influenced by the underlying arrhythmia mechanism. The aim of this study was to compare CI variability of PVCs in different myocardial disease entities, in order to gain insight into their arrhythmia mechanism. Methods Sixty-four patients with four underlying pathologies were included: idiopathic (n = 16), non-ischemic dilated cardiomyopathy (NIDCM) (n = 16), familial cardiomyopathy (PLN/LMNA) (n = 16), and post-MI (n = 16)-associated PVCs. The post-MI group was included as a reference, on account of its known re-entry mechanism. On Holter registrations, the first 20 CIs of the dominant PVC morphology were measured manually after which median ΔCI and mean SD of CI/√R-R (= CI of PVC corrected for underlying heart rate) were obtained. Two observers independently measured PVC CIs on pre-selected Holter registrations in order to determine inter- and intra-observer reliability. Results The largest ΔCI was seen in the PLN/LMNA group (220 ms (120–295)), the lowest in the idiopathic group (120 ms (100–190)). The ΔCI in the PLN/LMNA group was significantly larger than the post-MI group (220 ms (120–295) vs 130 ms (105–155), p = 0.023). Mean SD of CI/√R-R in the PLN/LMNA group was also significantly higher than in the post-MI group (p = 0.044). Inter- and intra-observer reliability was good (ICC = 0.91 vs 0.86 and 0.96 vs 0.77, respectively). Conclusions Low ΔCI and SD of CI/√R-R of idiopathic and NIDCM PVCs suggest that the underlying arrhythmia mechanisms might be re-entry or triggered activity. Abnormal automaticity or modulated parasystole are unlikely mechanisms. High CI variability in PLN/LMNA patients suggests that the re-entry and triggered activity are less likely mechanisms in this group.

Short- and Long-term Prognosis of Patients With Acute Heart Failure With and Without Diabetes: Changes Over the Last Three Decades. Diabetes Care 2018; 41:143-149. [PMID: 28982652 DOI: 10.2337/dc17-0544] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2017] [Accepted: 09/09/2017] [Indexed: 02/03/2023]
Abstract
OBJECTIVE We studied differences in long-term (i.e., 10 year) prognosis among patients with acute heart failure (HF) with and without diabetes over the last three decades. In addition, we investigated whether the degree of prognostic improvement in that period was comparable between patients with and without diabetes. RESEARCH DESIGN AND METHODS This prospective registry included all consecutive patients aged 18 years and older admitted to the Intensive Coronary Care Unit with acute HF in the period of 1985-2008. A total of 1,810 patients were included; 384 patients (21%) had diabetes. The outcome measure was the composite of all-cause mortality, heart transplantation, and left ventricular assist device implantation after 10-year follow-up. RESULTS The 10-year outcome in patients with diabetes was significantly worse than in those without diabetes (87% vs. 76%; adjusted hazard ratio [HR] 1.17 [95% CI 1.02-1.33]). Patients admitted in the last decade had a significantly lower 10-year event rate than patients admitted in the first two decades, both among patients without diabetes (adjusted HR 0.86 [95% CI 0.75-0.99]) and patients with diabetes (adjusted HR 0.80 [95% CI 0.63-1.00]). CONCLUSIONS The long-term outcome of patients with diabetes is worse than that of patients without diabetes. However, the long-term prognosis improved over time in both groups. Importantly, this improvement in long-term prognosis was comparable in patients with and without diabetes. Despite these promising results, more awareness for diabetes in patients with acute HF is necessary and there is still need for optimal treatment of diabetes in acute HF.

Early detection of left ventricular diastolic dysfunction using conventional and speckle tracking echocardiography in a large animal model of metabolic dysfunction. Int J Cardiovasc Imaging 2017; 34:743-749.

Abstract
Left ventricular (LV) diastolic dysfunction is one of the important mechanisms responsible for symptoms in patients with heart failure. The aim of the current study was to identify parameters that may be used to detect early signs of LV diastolic dysfunction in diabetic pigs on a high fat diet, using conventional and speckle tracking echocardiography. The study population consisted of 16 healthy Göttingen minipigs and 18 minipigs with experimentally induced metabolic dysfunction. Echocardiography measurements were performed at baseline and 3-month follow-up. The ratio of peak early (E) and late filling velocity (E/A ratio) and the ratio of E and the velocity of the mitral annulus early diastolic wave (E/Em ratio) did not change significantly in both groups. Peak untwisting velocity decreased in the metabolic dysfunction group (- 30.1 ± 18.5 vs. - 23.4 ± 15.5 °/ms) but not in controls (- 38.1 ± 23.6 vs. - 42.2 ± 23.0 °/ms), being significantly different between the groups at the 3-month time point (p < 0.05). In conclusion, whereas E/A ratio and E/Em ratio did not change significantly after 3 months of metabolic dysfunction, peak untwisting velocity was significantly decreased. Hence, peak untwisting velocity may serve as an important marker to detect early changes of LV diastolic dysfunction.

Predictive value of depression and anxiety for long-term mortality: differences in outcome between acute coronary syndrome and stable angina pectoris. Int J Cardiol 2017; 250:43-48. [PMID: 28992998 DOI: 10.1016/j.ijcard.2017.10.005] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2017] [Revised: 09/05/2017] [Accepted: 10/02/2017] [Indexed: 10/18/2022]
Abstract
BACKGROUND Since the early 2000s the treatment of choice for an acute myocardial infarction has moved from thrombolytic therapy to primary PCI (pPCI). As a result, the majority of patients undergoing PCI shifted from stable angina pectoris (SA) to acute coronary syndrome (ACS). Additionally the previously observed association between depression and anxiety and long-term outcome in patients who underwent a PCI may have been changed. The main objective of this study was to investigate the predictive value of depression and anxiety for 10-year mortality, in a cohort with post-PCI patients treated for SA versus patients treated for ACS. METHODS This prospective single center cohort consists of a consecutive series of patients (n=528) treated with PCI. At 1month post-PCI, patients completed the Dutch version of the Hospital Anxiety and Depression Scale (HADS). RESULTS After adjustment for baseline characteristics depression was associated with higher 10-year mortality post-PCI (HR 1.58 95% Confidence Interval [95% CI] 1.04-2.40). In the ACS population no association between depression and 10-year mortality was found (HR 1.05 95% CI 0.62-1.79), in contrast to the SA population (HR 1.97 95% CI 1.09-3.57). After additional adjustment for anxiety, depression was no longer associated with higher mortality. CONCLUSIONS Anxiety at baseline was associated with an increased 10-year mortality rate after PCI. Depression was also associated with higher 10-year mortality, however the association disappeared after additional adjustment for anxiety. This finding was more pronounced in patients presenting with SA as compared to those presenting with ACS, which might be a result of the increasing number of ACS patients treated with pPCI.

Abstract
OBJECTIVE The OPTICARE (OPTImal CArdiac REhabilitation) randomised controlled trial compared two advanced and extended cardiac rehabilitation (CR) programmes to standard CR for patients with acute coronary syndrome (ACS). These programmes were designed to stimulate permanent adoption of a heart-healthy lifestyle. The primary outcome was the SCORE (Systematic COronary Risk Evaluation) 10-year cardiovascular mortality risk function at 18 months follow-up. METHODS In total, 914 patients with ACS (age, 57 years; 81% men) were randomised to: (1) 3 months standard CR (CR-only); (2) standard CR including three additional face-to-face active lifestyle counselling sessions and extended with three group fitness training and general lifestyle counselling sessions in the first 9 months after standard CR (CR+F); or (3) standard CR extended for 9 months with five to six telephone general lifestyle counselling sessions (CR+T). RESULTS In an intention-to-treat analysis, we found no difference in the SCORE risk function at 18 months between CR+F and CR-only (3.30% vs 3.47%; p=0.48), or CR+T and CR-only (3.02% vs 3.47%; p=0.39). In a per-protocol analysis, two of three modifiable SCORE parameters favoured CR+F over CR-only: current smoking (13.4% vs 21.3%; p<0.001) and total cholesterol (3.9 vs 4.3 mmol/L; p<0.001). The smoking rate was also lower in CR+T compared with the CR-only (12.9% vs 21.3%; p<0.05). CONCLUSIONS Extending CR with extra behavioural counselling (group sessions or individual telephone sessions) does not confer additional benefits with respect to SCORE parameters. Patients largely reach target levels for modifiable risk factors with few hospital readmissions already following standard CR. TRIAL REGISTRATION NUMBER ClinicalTrials.gov NCT01395095; results.

Abstract
OBJECTIVES We aimed to develop a model to predict long-term mortality after percutaneous coronary intervention (PCI), to aid in selecting patients with sufficient life expectancy to benefit from bioabsorbable scaffolds. BACKGROUND Clinical trials are currently designed to demonstrate superiority of bioabsorbable scaffolds over metal devices up to 5 years after implantation. METHODS From 2000 to 2011, 19.532 consecutive patients underwent PCI in a tertiary referral hospital. Patients were randomly (2:1) divided into a training (N = 13,090) and validation (N = 6,442) set. Cox regression was used to identify determinants of long-term mortality in the training set and used to develop a risk model. Model performance was studied in the training and validation dataset. RESULTS Median age was 63 years (IQR 54-72) and 72% were men. Median follow-up was 3.6 years (interquartile range [IQR] 2.4-6.8). The ratio elective vs. non-elective PCIs was 42/58. During 88,620 patient-years of follow-up, 3,156 deaths occurred, implying an incidence rate of 35.6 per 1,000. Estimated 5-year mortality was 12.9%.Regression analysis revealed age, body mass index, diabetes mellitus, renal insufficiency, prior myocardial infarction, PCI indication, lesion location, number of diseased vessels and cardiogenic shock at presentation as determinants of mortality. The long-term risk model showed good discrimination in the training and validation sets (c-indices 0.76 and 0.74), whereas calibration was appropriate. CONCLUSIONS A simple risk model, containing 9 baseline clinical and angiographic variables effectively predicts long-term mortality after PCI and may possibly be used to select suitable patients for bioabsorbable scaffolds.

Abstract
AIMS This study aimed to evaluate the prognostic value of high-sensitivity C-reactive protein (hsCRP) during 10-year follow-up after percutaneous coronary intervention (PCI). METHODS AND RESULTS Between April and October 2002, hsCRP was measured in 468 all-comer patients who underwent PCI with sirolimus-eluting stent implantation for stable coronary artery disease or acute coronary syndrome. The primary endpoint was the composite of all-cause mortality or myocardial infarction at 10-year follow-up. Kaplan-Meier event curves displayed ongoing divergence of the hsCRP groups (hsCRP <1 mg/L: 14.7% vs. 1-3 mg/L: 31.1% vs. >3 mg/L: 43.1%). After adjustment for established cardiovascular risk factors and clinical presentation in a Cox regression model, higher CRP levels were associated with a higher incidence of the composite endpoint (>3 mg/L vs. <1 mg/L: HR 2.87, 95% CI: 1.69-4.87, p<0.001; 1-3 mg/L vs. <1 mg/L: HR 2.30, 95% CI: 1.31-4.03, p=0.004). Although adding hsCRP to a prediction model containing conventional cardiovascular risk factors did not significantly improve discriminatory power (area under the receiver operating characteristic curve 0.71 to 0.73, p=0.56), hsCRP was able to improve risk classification (net reclassification index=0.40, p=<0.001). CONCLUSIONS In patients undergoing PCI, higher CRP levels at the time of the procedure are predictive for 10-year mortality and myocardial infarction. High-sensitivity CRP may be a useful biomarker to improve further risk assessment in patients undergoing PCI.

Abstract
Background Speckle tracking echocardiography (STE) is an echocardiography modality that is able to measure left ventricular (LV) characteristics, including rotation, strain and strain rate. Strain measures myocardial fibre contraction and relaxation. This study aims to assess the effect of renal sympathetic denervation (RDN) on functional myocardial parameters, including STE, and to identify potential differences between responders and non-responders. Methods The study population consisted of 31 consecutive patients undergoing RDN in the context of treatment for resistant hypertension. Patients were included between December 2012 and June 2014. Transthoracic echocardiography and speckle tracking analysis was performed at baseline and at 6 months follow-up. Results The study population consisted of 31 patients with treatment-resistant hypertension treated with RDN (mean age 64 ± 10 years, 15 men). The total study population could be divided into responders (n = 19) and non-responders (n = 12) following RDN. RDN reduced office blood pressure by 18.9 ± 26.8/8.5 ± 13.5 mmHg (p < 0.001). A significant decrease was seen in LV posterior wall thickness (LVPWd) (0.47 ± 1.0 mm; p = 0.020), without a significant change in the LV mass index (LVMI). In the total cohort, only peak late diastolic filling velocity (A-wave velocity) decreased significantly by 5.3 ± 13.2 cm/s (p = 0.044) and peak untwisting velocity decreased significantly by 14.5 ± 28.9°/s (p = 0.025). Conclusion RDN reduced blood pressure and significantly improved functional myocardial parameters such as A-wave velocity and peak untwisting velocity in patients with treatment-resistant hypertension, suggesting a potential beneficial effect of RDN on myocardial mechanics.

Abstract
BACKGROUND Cardiac rehabilitation (CR) is recommended as secondary prevention in primary percutaneous coronary intervention (pPCI) patients. This study was conducted to expand the knowledge about age-effects of CR in pPCI patients. The aim of this study was to compare changes in subjective health status (SHS) during and after CR between patients <60years and patients ≥60years, who underwent pPCI after myocardial infarction. METHODS Between 2009 and 2011, in total 282 pPCI patients who participated in CR were included. Patients completed the Short Form 12 (SF-12) questionnaire at baseline (pre-CR), 3months (post-CR) and 12months follow-up. Patients were divided into two age-groups, <60years versus ≥60years. To compare improvements in SHS between groups, Generalized Estimating Equations (GEE) analyses were performed. RESULTS The mean physical component summary (PCS) score improved over time in both groups and even reached mean levels of the normative Dutch population. The improvement on the PCS score was equal in both age groups. The mental component summary (MCS) score also improved in both groups. Patients <60years reported on average more improvement on the MCS score than patients ≥60years (Exp(B) 1.019; 95%CI 1.009-1.030; P<0.001). However, mean levels of the normative Dutch population were not reached by patients <60years. CONCLUSION Even though pPCI patients <60years reported more improvement on the MCS score, mean levels of the normative Dutch population were not reached. Therefore, a tailored CR program with more focus on their mental status, may be beneficial in younger patients.

Abstract
No disease-specific instruments exist in Dutch, French, Italian, and Swedish to measure health status in idiopathic pulmonary fibrosis (IPF) and other interstitial lung diseases (ILDs). The King's Brief Interstitial Lung Disease (K-BILD) is a 15-item validated questionnaire assessing health status in patients with ILD. The aim of this study was to translate and validate the K-BILD to French, Italian, Swedish, and Dutch versions. The K-BILD was translated following a forward-backward multistep procedure and tested in structured patient interviews. Subsequently, 195 outpatients with ILD were asked to complete K-BILD, St. George's Respiratory Questionnaire (SGRQ), and Euroqol EQ-5D-5L (EQ5D), twice, 2 weeks apart. Internal consistency, concurrent validity, and repeatability were determined. No major difficulties occurred in the translation processes. The K-BILD was considered comprehensible and relevant by patients. One hundred seventy-six patients (108 IPF and 68 other ILDs) completed the translated K-BILD. Internal consistency was good for all K-BILD modules (Cronbach's α 0.70-0.93). Concurrent validity of K-BILD was strong compared with SGRQ ( r = -0.86) and EQ5D ( r = 0.68), low with transfer capacity of the lung for carbon monoxide corrected for hemoglobin ( r = 0.33) and with forced vital capacity ( r = 0.35). The K-BILD and its domains were repeatable over 2 weeks; intraclass correlation coefficients were 0.86-0.93 ( n = 159). Known groups validity showed K-BILD was able to discriminate between patients based on severity of disease. K-BILD's validity and reliability for patients with IPF was similar to that of other ILDs. The French, Italian, Swedish, and Dutch translated K-BILD questionnaires were well-received by patients and demonstrated excellent validity comparable to the original English K-BILD.

Abstract
BACKGROUND Poor subjective health status significantly predicted short-term mortality in patients with coronary artery disease (CAD). However, the relation between subjective health status and long-term mortality remains limited in patients treated with PCI. The aim of this study is to investigate the association between subjective health status and 14-year mortality in patients treated with percutaneous coronary intervention (PCI). METHODS A consecutive cohort with 1111 patients treated for CAD who completed the SF-36 questionnaire was included between 2001 and 2002 as part of the RESEARCH registry. RESULTS After adjustment, physical functioning (HR: 1.96; 95% CI: 1.59-2.43), social functioning (HR: 1.53; 95% CI: 1.24-1.88), role limitations due to physical functioning (HR: 1.75; 95% CI: 1.41-2.16), role limitations due to emotional functioning (HR: 1.34; 95%CI: 1.08-1.67), mental health (HR: 1.52; 95% CI: 1.24-1.88), vitality (HR: 1.66; 95% CI: 1.35-2.03), bodily pain (HR: 1.63; 95% CI: 1.32-2.02) and general health (HR: 1.82; 95% CI: 1.49-2.23) were all associated with an increased risk of 14-year mortality. CONCLUSION Physical and mental subjective health status as measured with the SF-36 appeared to be a strong predictor for 14-year mortality in post-PCI patients.

Impact of Early Coronary Revascularization on Long-Term Outcomes in Patients With Myocardial Ischemia on Dobutamine Stress Echocardiography. Am J Cardiol 2016; 118:635-40. [PMID: 27394410 DOI: 10.1016/j.amjcard.2016.06.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2016] [Revised: 06/03/2016] [Accepted: 06/03/2016] [Indexed: 01/09/2023]
Abstract
The role of early coronary revascularization in the management of stable coronary artery disease remains controversial. The aim of this study was to evaluate the impact of early coronary revascularization on long-term outcomes (>10 years) after an ischemic dobutamine stress echocardiography (DSE) in patients with known or suspected coronary artery disease. Patients without stress-induced ischemia on DSE and those who underwent late coronary revascularization (>90 days after DSE) were excluded. The final study cohort consisted of 905 patients. A DSE with a peak wall motion score index of 1.1 to 1.7 was considered mild to moderately abnormal (n = 460), and >1.7 was markedly abnormal (n = 445). End points were all-cause and cardiac mortality. The impact of early coronary revascularization on outcomes was assessed using Kaplan-Meier survival analysis and Cox's proportional hazard regression models. Early coronary revascularization was performed in 222 patients (percutaneous coronary intervention in 113 [51%] and coronary artery bypass grafting in 109 patients [49%]). During a median follow-up time of 10 years (range 8 to 15), 474 deaths (52%) occurred, of which were 241 (51%) due to cardiac causes. Kaplan-Meier survival curves showed that both in patients with a markedly abnormal DSE and a mild-to-moderately abnormal DSE, early revascularization was associated with better long-term outcomes. Multivariable analyses revealed that early revascularization had a beneficial effect on all-cause mortality (hazard ratio 0.60, 95% confidence interval 0.46 to 0.79) and cardiac mortality (hazard ratio 0.49, 95% confidence interval 0.34 to 0.72). In conclusion, early coronary revascularization has a beneficial impact on long-term outcomes in patients with myocardial ischemia on DSE. Early coronary revascularization was associated with better outcomes not only in patients with a markedly abnormal DSE but also in those with a mild to moderately abnormal DSE.

The unnatural history of pulmonary stenosis up to 40 years after surgical repair. Heart 2016; 103:273-279.

Abstract
OBJECTIVE To provide prospective information on long-term outcome after surgical correction of valvular pulmonary stenosis (PS). METHODS Fifty-three consecutive patients operated for PS during childhood between 1968 and 1980 in one centre are followed longitudinally for 37±3.4 years, including extensive in-hospital examination every 10 years. RESULTS Survival information was available in 100% of the original 53 patients. Cumulative survival was 94% at 20 years and 91% at 40 years. Excluding perioperative mortality (<30 days), survival was 94% at 40 years. Of 46 eligible survivors, 29 participated in the in-hospital examination and 15 gave permission to use their hospital records (96% participation). Cumulative event-free survival was 68% after 40 years: 25% needed a reintervention, 12% underwent pacemaker implantation and 9% had supraventricular arrhythmias. Early reinterventions were mainly for residual PS, late reinterventions for pulmonary regurgitation. Subjective health status was good. Exercise capacity was normal in 74% (median 96 (82-107)% of expected workload). Right ventricular and left ventricular (LV) dysfunction was found in 13% and 41%, respectively. The use of a transannular patch and younger age at surgery were predictive for late events (HR 3.02 (95% CI 1.09 to 8.37) and HR 0.81/year (95% CI 0.66 to 0.98), respectively). Use of inflow occlusion compared with cardiopulmonary bypass showed a trend towards more reinterventions (HR 3.19 (95% CI 0.97 to 10.47)). CONCLUSIONS Survival up to 40 years after successful PS repair is nearly normal. Subjective health status is good and there is a low incidence of arrhythmias. Reinterventions, however, are necessary in one-quarter and 40 years postoperatively several patients show LV dysfunction.

Abstract
The prognostic value of dobutamine stress echocardiography (DSE) at >10-year follow-up is unknown. The aim of this study was to assess the very long-term prognostic value of DSE in a high-risk cohort of patients with known or suspected coronary artery disease. This prospective, single-center study included 3,381 patients who underwent DSE from January 1990 to January 2003. Two-dimensional echocardiographic images were acquired at rest, during dobutamine stress, and during recovery. Follow-up events were collected and included overall mortality, cardiac death, nonfatal myocardial infarction, and revascularization. The incremental value of DSE in the prediction of selected end points was evaluated using multivariate Cox proportional hazard analysis. During a mean follow-up of 13 ± 3.2 years (range 7.3 to 20.5 years), there were 1,725 deaths (51%), of which 1,128 (33%) were attributed to cardiac causes. Patients with an abnormal DSE had a higher mortality rate (44% vs 35% at 15-year follow-up, p <0.001) than those with a normal DSE. When comparing echocardiographic variables at rest to variables at maximum dose dobutamine, the chi-square of the test improved from 842 to 870 (p <0.0001) and from 684 to 740 (p <0.0001) for all-cause mortality and cardiac death, respectively. DSE provided incremental value in predicting all-cause mortality, cardiac death, and hard cardiac events. There seems, however, to be a "warranty period" of approximately 7 years, when the survival curves of a normal and abnormal DSE no longer diverge.

Abstract
AIMS Many studies have examined the prognostic value of myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) for the prediction of short- to medium-term outcomes. However, the long-term prognostic value of MPI in patients with diabetes mellitus remains unclear. Therefore, this study assessed the long-term prognostic value of MPI in a high-risk cohort of patients with diabetes mellitus. METHODS AND RESULTS A high-risk cohort of 207 patients with diabetes mellitus who were unable to undergo exercise testing underwent dobutamine stress MPI. Follow-up was successful in 206 patients; 12 patients were excluded due to early revascularization. The current data are based on the remaining 194 patients. Follow-up end points were all-cause mortality, cardiac mortality, and nonfatal myocardial infarction. The Kaplan-Meier survival curves were constructed, and univariable and multivariable analyses were performed to identify predictors of long-term outcome. During a mean follow-up of 8.1 ± 5.9 years, 134 (69%) patients died of which 68 (35%) died due to cardiac causes. Nonfatal myocardial infarction occurred in 24 patients (12%), and late (>60 days) coronary revascularization was performed in 61 (13%) patients. Survival analysis showed that MPI provided optimal risk stratification up to 4 years after testing. After that period, the outcome was comparable in patients with normal and abnormal MPI. Multivariable analyses showed that MPI provided incremental prognostic value up to 4 years after testing. CONCLUSION In high-risk patients with diabetes mellitus, dobutamine MPI provides incremental prognostic information in addition to clinical data for a 4-year period after testing.

Abstract
QRS duration is of prognostic relevance in patients with several underlying heart diseases. Short-term data also show the prognostic value of QRS duration in lower risk groups of patients. The aim of this study was to investigate the long-term prognostic value of QRS duration in patients with known or suspected coronary artery disease. The study cohort consisted of 512 patients (308 men, mean age 60 ± 11 years) who underwent myocardial perfusion imaging (MPI) for the evaluation of suspected or known coronary artery disease. Follow-up data were collected to assess the prognostic value of QRS duration, alongside clinical characteristics and MPI results. End points were cardiac death and cardiac death or nonfatal myocardial infarction (MI). During a mean follow-up of 8.6 ± 5.2 years, 290 patients (60%) died, with 139 deaths (27%) attributable to cardiac causes. Nonfatal MI occurred in 28 patients (6%), and 127 patients (25%) underwent late coronary revascularization (>3 months). Patients with QRS duration <120 ms had annualized cardiac death rates and cardiac death or nonfatal MI rates of 2.2% and 2.3%, respectively, compared with those of 4.1% and 4.4% in patients with QRS duration ≥120 ms. Multivariate models identified QRS duration ≥120 ms as an independent predictor of both end points, on top of clinical characteristics and MPI results. In conclusion, QRS duration ≥120 ms is an independent predictor of cardiac death and cardiac death or nonfatal MI, after adjustment for clinical characteristics and MPI results.

Abstract
OBJECTIVE Despite multiple studies on the diagnostic and prognostic use of dobutamine myocardial perfusion imaging (MPI), information on its long-term prognostic value is scarce. The aim of this study was to assess the value of this technique for the prediction of very long-term outcome. METHODS A total of 721 patients with limited exercise capacity underwent dobutamine MPI for the evaluation of suspected or known coronary artery disease. 719 of 721 patients attended follow-up (99.7%). Twenty-eight patients who underwent early coronary revascularization were excluded from analysis. Endpoints were all-cause mortality, cardiac death, nonfatal infarction, and coronary revascularization. Kaplan-Meier survival curves were constructed, and univariate and multivariate analyses were performed to identify predictors of long-term outcome. RESULTS The mean age of patients was 60 ± 11 years, and 61% were male. Myocardial perfusion abnormalities were present in 381 patients (55%) and included fixed defects in 190 patients (27%) and reversible defects in 191 patients (28%). During a median follow-up time of 14 years (range 0-16), 295 deaths occurred (43%), of which 158 were cardiac deaths (23%). Nonfatal myocardial infarction occurred in 35 (5%), and late coronary revascularization was performed on 133 patients (19%). An abnormal dobutamine MPI provided significant prognostic information for prediction of cardiac death, hard cardiac events, and MACE, after adjustment for significant clinical variables and stress test variables. CONCLUSIONS Dobutamine MPI provides incremental prognostic information for the prediction of cardiovascular outcomes in patients with limited exercise capacity. The long-term prognosis of patients with limited exercise capacity who have an abnormal dobutamine MPI is significantly worse than those with a normal MPI.

Abstract
Myocardial perfusion single-photon emission computed tomography is a routine technique for the evaluation of coronary artery disease. However, information on the very long term prognostic value of dobutamine stress single-photon emission computed tomographic myocardial perfusion imaging (MPI) in patients with limited exercise capacity is scarce. The aim of this study was to assess the long-term prognostic value of dobutamine stress technetium-99m ((99m)Tc)-sestamibi MPI in these patients. The study population consisted of a high-risk cohort of 531 consecutive patients with limited exercise capacity who underwent dobutamine stress (99m)Tc-sestamibi MPI for the assessment of known or suspected coronary artery disease. Follow-up was successful in 528 patients. Because of early revascularization, 55 patients were excluded. The present data are based on 473 patients. The end points were all-cause mortality, cardiac death, nonfatal myocardial infarction, and late (>60 days) coronary revascularization. Kaplan-Meier survival curves were performed and univariate and multivariate analyses were performed to identify predictors of very long term outcome. The mean age of the patients was 61 ± 12 years, and 58% were men. Abnormal results (defined as the presence of reversible or fixed defects) were observed in 312 patients (66%). During a mean follow-up period of 11.3 ± 6.7 years, 287 patients (61%) died (all-cause mortality), of whom 125 (26%) died due to cardiac causes. Nonfatal myocardial infarction occurred in 59 patients (12%). Late coronary revascularization was performed in 61 patients (13%). Univariate predictors of major cardiac events included age, male gender, previous infarction, diabetes mellitus, history of angina, heart failure, ST-segment changes, abnormal results on (99m)Tc-sestamibi scan, reversible defect, fixed defect, summed rest score, and summed stress score. Multivariate analysis identified abnormal results on MPI as a strong independent predictor of major adverse cardiac events. In conclusion, in patients with limited exercise capacity, dobutamine stress (99m)Tc-sestamibi single-photon emission computed tomography provides incremental prognostic information in addition to clinical and stress test parameters for the prediction of very long term outcomes.

Abstract
BACKGROUND Depression has been shown to be an independent risk factor for short-term mortality in patients with coronary artery disease (CAD). There are studies suggesting that depression might also be associated with long-term mortality. Anxiety has also been associated with mortality. This study aimed to further investigate the predictive value of depression and anxiety symptoms on all-cause mortality, 10 years after percutaneous coronary intervention (PCI). METHODS The study population comprised a consecutive series of CAD patients (n = 1411) treated with PCI between September 2001 and October 2002 at the Erasmus Medical Centre, Rotterdam. The Hospital Anxiety and Depression Scale (HADS) was completed by 1112 patients at baseline to assess levels of depression and anxiety. The endpoint was defined as all-cause mortality. RESULTS The prevalence of depression and anxiety was 24.8% and 27.7%, respectively. The cumulative all-cause mortality rate in depressed patients was 37% versus 20% in non-depressed patients (log-rank p < 0.001). After adjustment, depression remained a predictor of all-cause mortality (hazard ratio (HR) 1.77; 95% confidence interval (CI) 1.36-2.29). Cumulative survival rates did not differ for anxious versus non-anxious patients (log-rank p = .79). However, after adjustment, anxiety was associated with an increased risk for all-cause mortality (HR 1.50; 95% CI 1.14-1.98). A sub-analysis showed that cumulative survival rates did not differ for depressed and anxious patients versus depressed but non-anxious patients (log-rank p = 0.46). CONCLUSIONS Depression is associated with an increased risk of 77% for all-cause mortality, 10 years post-PCI, independently of anxiety. Although anxiety was associated with all-cause mortality, it has no additional value in the case of co-occurring depression.
