Exercise ankle brachial index adds important prognostic information on long-term out-come only in patients with a normal resting ankle brachial index. Atherosclerosis 2011; 216:365-9. [PMID: 21397231 DOI: 10.1016/j.atherosclerosis.2010.10.051] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2010] [Revised: 10/06/2010] [Accepted: 10/06/2010] [Indexed: 11/18/2022]
Abstract
BACKGROUND The clinical value of exercise ankle brachial index (ABI) is still unclear, especially in patients with normal resting ABI. METHOD 2164 patients performed a single-stage treadmill exercise test to diagnose or evaluate PAD. The population was divided into two groups: a normal resting ABI (resting ABI≥0.90) and PAD (resting ABI<0.90). Patients with a normal resting ABI were divided into 4 exercise ABI groups: exercise ABI<0.90, 0.90-0.99, 1.00-1.09 and 1.10-1.29 (reference). RESULTS Mean follow-up was 5 years. Exercise ABI added significant prognostic information on all cause long-term mortality only in patients with normal resting ABI (p-value 0.014, HR 0.99 95% CI (0.98-0.99)), not in patients with PAD. Fifty years or older (OR 2.93 95% CI (1.65-5.20)) and resting systolic blood pressure>140 mmHg (OR 2.18 95% CI (1.35-3.55)) were associated with an abnormal exercise ABI in patients with a normal resting ABI. Mortality rate increased when the exercise ABI became worse (p trend 0.0001) with a 2.5-fold increase mortality risk in patients with a normal resting ABI but exercise ABI <0.90 (HR 2.56, 95% CI (1.11-5.91)). CONCLUSION In patients with a normal resting ABI, treadmill exercise ABI added important prognostic information on long-term mortality. Based on our results we recommend that at least all patients suspected for PAD, with a resting ABI≥0.90, who are 50 years or older and having hypertension should undergo treadmill exercise testing.

Abstract
IMPORTANCE OF THE FIELD In patients undergoing vascular surgery there is a high incidence of adverse cardiac events, due to sudden coronary plaque rupture. The non-lipid lowering or pleiotropic effects of statins can help reduce adverse cardiovascular events associated with vascular surgery. AREAS COVERED IN THIS REVIEW The evidence for perioperative use of fluvastatin, as well as other statins, in high-risk surgery patients is summarized in this review. Data on pharmacokinetics and metabolism is presented, together with considerations on possible drug interactions in the perioperative period. WHAT THE READER WILL GAIN The reader will gain a comprehensive understanding of the existing safety and efficacy data for fluvastatin and other statins in the perioperative period. The practical considerations of perioperative fluvastatin therapy will be presented, including potential side-effects and management of the early non-oral phase immediately post surgery. Finally, advice on when to initiate therapy and safety recommendations are offered. TAKE HOME MESSAGE In patients scheduled for high-risk vascular surgery, fluvastatin improves postoperative outcome, reducing the incidence of myocardial damage by approximately 50% in the first 30 days following vascular surgery. In comparison with placebo, fluvastatin was not associated with a rise in liver enzymes or creatine kinase levels. To bridge the non-oral phase, an extended-release formula is recommended.

Abstract
INTRODUCTION In the perioperative setting, there is still a high incidence of adverse cardiac events due to sudden coronary plaque rupture or oxygen supply-demand imbalance. β-Blockers play an important role in preventing these cardiac events. Discussion, however, remains on the side effects accompanying this therapy. AREAS COVERED The evidence for perioperative use of β-blockers is summarized in this review in terms of risk reduction, perioperative safety and current clinical use. Furthermore, data on pharmacokinetics, pharmacodynamics and pharmacogenetics are presented. EXPERT OPINION In perioperative care, β-blockers are recommended and can be given safely when started early in a low dose, titrated to heart rate. In the future, there could be a place for added perioperative short-acting β-blockers to further optimize heart rate control.

Abstract
Thoracic aortic aneurysms and dissections are a main feature of connective tissue disorders, such as Marfan syndrome and Loeys-Dietz syndrome. We delineated a new syndrome presenting with aneurysms, dissections and tortuosity throughout the arterial tree in association with mild craniofacial features and skeletal and cutaneous anomalies. In contrast with other aneurysm syndromes, most of these affected individuals presented with early-onset osteoarthritis. We mapped the genetic locus to chromosome 15q22.2-24.2 and show that the disease is caused by mutations in SMAD3. This gene encodes a member of the TGF-β pathway that is essential for TGF-β signal transmission. SMAD3 mutations lead to increased aortic expression of several key players in the TGF-β pathway, including SMAD3. Molecular diagnosis will allow early and reliable identification of cases and relatives at risk for major cardiovascular complications. Our findings endorse the TGF-β pathway as the primary pharmacological target for the development of new treatments for aortic aneurysms and osteoarthritis.

Abstract
Approximately 100 million people undergo noncardiac surgery annually worldwide. It is estimated that around 3% of patients undergoing noncardiac surgery experience a major adverse cardiac event. Although cardiac events, like myocardial infarction, are major cause of perioperative morbidity or mortality, its true incidence is difficult to assess. The risk of perioperative cardiac complications depends mainly on two conditions: (1) identified risk factors, and (2) the type of the surgical procedure. On that basis, different scoring systems have been developed in order to accurately assess the perioperative cardiac risk and to improve the patient management. Importantly, patients with estimated high risk should be tested preoperatively by non-invasive cardiac imaging modalities. According to test results, they can proceed directly to planed surgery with the use of cardioprotective drugs (beta-blockers, statins, aspirin), or to myocardial revascularization prior to non-cardiac surgery. In this review, we discuss the role of clinical cardiac risk factors, laboratory measurements, additional non-invasive cardiac testing, and consequent strategies in perioperative management of patients undergoing noncardiac surgery.

Abstract
BACKGROUND Previous studies suggested that hypofibrinolysis is associated with increased risk of peripheral arterial disease. Thrombin activatable fibrinolysis inhibitor (TAFI) has been identified as an important inhibitor of fibrinolysis. The aim of our study was to assess the role of TAFI in young patients with peripheral arterial disease. METHODS In a single-center case-control study we measured plasma TAFI antigen levels and functional TAFI in consecutive young patients (men 18-45 years and women 18-55 years) with a first manifestation of peripheral arterial disease and compared these with a population-based control group. RESULTS A total of 47 peripheral arterial disease patients and 141 controls (mean age 43) were included. Intact TAFI antigen levels were significantly higher in patients with peripheral arterial disease (112.4±21.1%) than in controls (104.9±19.9%, p=0.03). The risk of peripheral arterial disease increased with 18% (OR 1.18; CI 1.01-1.34) per 10% increase of TAFI antigen. Functional TAFI levels were slightly higher in patients compared to controls, however this difference was not significant. For individuals with the highest functional TAFI levels, above the 90th percentile, the increased risk for peripheral arterial disease was most pronounced (OR 3.1; CI 1.02-9.41). CONCLUSION High TAFI levels are associated with increased risk of premature peripheral arterial disease.

Abstract
BACKGROUND Vascular surgery patients are at increased risk for late sudden cardiac death. Identification of patients at risk during surgery offers the opportunity for focused therapy. METHODS We monitored 483 vascular surgery patients who had no documented history of arrhythmias to identify perioperative new-onset ventricular tachyarrhythmia (VT) and myocardial ischemia using a continuous electrocardiographic (ECG) device for 72 hours. Cardiac risk factors, left ventricular ejection fraction (LVEF), medical therapy, inflammation status, and perioperative ischemia in relation to arrhythmia were noted in all patients. During follow-up, event-based outcomes analysis was used to describe survival. RESULTS New-onset perioperative VT was detected in 33 patients (6.8%). A higher percentage of patients experiencing perioperative VT had reduced LVEF preoperatively than those without VT (24% vs 12%; P = .04). Additionally, fewer patients experiencing VT were receiving statins than those without (70% vs 85%; P = .02). Patients experiencing VT had a higher incidence of myocardial ischemia (30% vs 18%; P = .10). Perioperative VT was preceded by ischemia in only 60% of the cases. The overall cohort survival was 83% at 24-month follow-up (interquartile range [IQR], 1.1-1.3). Sudden cardiac death free survival among patients experiencing VT was less than in those without (79% vs 92%; P = .02). After adjusting for gender, cardiac risk factors, and type of surgery, new-onset perioperative VT was associated with sudden cardiac death (hazard ratio [HR], 2.6; 95% confidence interval [CI], 1.1-5.8). CONCLUSION Perioperative VT is likely to be associated with late sudden cardiac death and decreased survival. Continuous perioperative ECG is an effective method to identify VT and may allow improved management of these patients.

Abstract
Aortic dissection is a devastating cardiovascular condition with an incidence of 3,5:100 000. It is classified according to anatomic extent, mechanism of lesion, duration from index event and course (uncomplicated vs. complicated). Intramural hematoma and penetrating aortic ulcers share many of the features of classic dissections, but tend to occur in older patients with advanced atherosclerosis. In uncomplicated type-B dissection, conservative treatment with tight blood pressure and heart rate control is safe and effective. Early stent-graft implantation may, however, result in more favorable aortic remodeling and reduced late complications. For acute complicated cases intervention is usually required. Stent-graft coverage of the entry tear frequently resolves malperfusion, but the role of the false lumen in organ perfusion must be assessed and endovascular revascularization performed if necessary. In chronic type-B dissections, coverage of the entry tear likely results in continued pressurization of the false lumen due to rigidity of the dissecting membrane and distal fenestrations. Better understanding of the different disease mechanisms involved, imaging advances and introduction of dedicated stent-grafts are expected to further improve patient outcomes in the future. Primary and secondary pharmacological prevention, stricter follow-up protocols and screening of family members may also prove valuable. Better patient selection will allow preventive treatment with low morbidity for those at higher risk of complications.

Abstract
BACKGROUND Although most patients who improve in clinical status after cardiac resynchronization therapy (CRT) also show a significant left ventricular (LV) reverse remodeling, some patients do not show echocardiographic improvement. The aim of the present study was to evaluate the degree of agreement between clinical and echocardiographic response to CRT in a large cohort of heart failure patients, and to evaluate the characteristics of patients with clinical response but without echocardiographic response. METHODS In 440 consecutive heart failure patients (mean age 66 ± 11 years, 81% men) treated with CRT, agreement between clinical and echocardiographic responses at 6 months of follow-up were evaluated. The combined clinical response was defined as: ≥1-point New York Heart Association functional class improvement or ≥15% increase in 6-minute walk test. Echocardiographic response was defined by a reduction in LV end-systolic volume (LVESV) ≥15%. RESULTS At 6 months of follow-up, clinical response was observed in 84% (n = 370) of the patients. Significant reduction in LVESV was noted in 63% (n = 276). The majority of patients who improved clinically did show LV reverse remodeling (72%, n = 268). Importantly, 28% (n = 102) of patients who improved clinically did not show significant LV reverse remodeling. The patients with clinical response but without echocardiographic response had more often ischemic heart failure as compared to patients with positive clinical and echocardiographic response (69.6% vs 57.5%; P = .021). Moreover, patients with such discordant responses had more narrow QRS complex (148 ± 31 vs 159 ± 31 milliseconds; P = .004), and showed less LV dyssynchrony than patients with concordant positive responses (90 ± 77 vs 171 ± 105 milliseconds; P < .001). CONCLUSIONS Although there is a good concordance between echocardiographic and clinical response to CRT, up to 28% of the population experienced clinical response without significant LV reverse remodeling. Subjects with such discrepant responses have more frequently ischemic heart failure and show more narrow QRS complex and less LV dyssynchrony than patients with both clinical and echocardiographic response.

Abstract
BACKGROUND Cardiac troponin T (cTnT) assays with increased sensitivity might increase the number of positive tests. Using the area under the curve (AUC) with serial sampling of cTnT an exact quantification of the myocardial damage size can be made. We compared the prognosis of vascular surgery patients with integrated cTnT-AUC values to continuous and standard 12-lead electrocardiography (ECG) changes. METHODS 513 Patients were monitored. cTnT sampling was performed on postoperative days 1, 3, 7, 30 and/or at discharge or whenever clinically indicated. If cTnT release occurred, daily measurements of cTnT were performed, until baseline was achieved. CTnT-AUC was quantified and divided in tertiles. All-cause mortality and cardiovascular events (cardiac death and myocardial infarction) were noted during follow-up. RESULTS 81/513 (16%) Patients had cTnT release. After adjustment for gender, cardiac risk factors, and site and type of surgery, those in the highest cTnT-AUC tertile were associated with a significantly worse cardiovascular outcome and long-term mortality (HR 20.2; 95% CI 10.2-40.0 and HR 4.0; 95% CI 2.0-7.8 respectively). Receiver operator analysis showed that the best cut-off value for cTnT-AUC was <0.01 days*ng m for predicting long-term cardiovascular events and all-cause mortality. CONCLUSION In vascular surgery patients quantitative assessment of cTnT strongly predicts long-term outcome.

Abstract
Diabetes mellitus (DM) and left ventricular dysfunction (LVD) are often coexistent and invariably associated with increased mortality. Data on long-term prognosis of "isolated" diastolic LVD in diabetics are lacking; therefore, we evaluated these prognostic implications in patients with peripheral arterial disease (PAD) and DM. Using echocardiography, 1321 patients were screened for diastolic, systolic (ejection fraction <50%) or combined LVD. Diastolic LVD was diagnosed based on the ratio of early rapid filling to late filling due to atrial contraction, pulmonary vein flow, and deceleration time. Patients using glucose-lowering drugs or insulin or with a fasting glucose level >6.1 mmol/L were diagnosed with DM. The primary end point was occurrence of cardiovascular death during a mean follow-up of 2.5 +/- 1.9 years. In the total population, DM was diagnosed in 518 patients (39%), and diastolic, systolic, or combined LVD was present in 356 patients (27%), 102 patients (8%), or 156 patients (12%), respectively. In diabetic patients, diastolic and systolic LVDs were associated with increased cardiovascular mortality (hazard ratio 1.8, 95% confidence interval 1.03 to 3.03; hazard ratio 3.1, 95% confidence interval 1.46 to 6.38). In nondiabetic patients, the same association between diastolic or systolic LVD and outcome was observed (hazard ratio 2.2, 95% confidence interval 1.30 to 3.74; hazard ratio 3.9, 95% confidence interval 2.00 to 7.52). Combined systolic and diastolic LVD had the worst prognosis. In conclusion, diabetic patients with PAD have an increased prevalence of isolated systolic and combined LVD. In patients with PAD the presence of isolated diastolic, systolic, or combined LVD was independently and equally associated with increased cardiovascular mortality, irrespective of the concomitant presence of DM.

Abstract
Preoperative cardiac risk assessment is the cornerstone of rationale perioperative management that guides invasive surgical interventions. In addition to clinical risk factors, a simple screening biomarker would be useful for identifying those surgical patients who might benefit from additional cardiac testing or therapeutic interventions. Preoperative plasma levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) are predictors of cardiac events after noncardiac surgery. NT–proBNP is synthesized in the ventricular myocardium in response to ventricular wall stress. To further increase the diagnostic accuracy of NT-proBNP for preoperative screening, it is important to identify confounding factors that influence NT-proBNP levels and their interaction with identifying risks for adverse cardiac events. Moreover, until now the available data from previous studies has been unable to consistently recognize the optimal discriminatory threshold for NT-proBNP. Currently, the ongoing DECREASE-VI study is conducted to evaluate whether current preoperative risk stratification can be improved by incorporating NT-proBNP measurements.

Abstract
BACKGROUND Major vascular surgery patients are at high risk for developing asymptomatic perioperative myocardial ischemia reflected by a postoperative troponin release without the presence of chest pain or electrocardiographic abnormalities. Long-term prognosis is severely compromised and characterized by an increased risk of long-term mortality and cardiovascular events. Current guidelines on perioperative care recommend single antiplatelet therapy with aspirin as prophylaxis for cardiovascular events. However, as perioperative surgical stress results in a prolonged hypercoagulable state, the postoperative addition of clopidogrel to aspirin within 7 days after perioperative asymptomatic cardiac ischemia could provide improved effective prevention for cardiovascular events. STUDY DESIGN DECREASE-VII is a phase III, randomized, double-blind, placebo-controlled, multicenter clinical trial designed to evaluate the efficacy and safety of early postoperative dual antiplatelet therapy (aspirin and clopidogrel) for the prevention of cardiovascular events after major vascular surgery. Eligible patients undergoing a major vascular surgery (abdominal aorta or lower extremity vascular surgery) who developed perioperative asymptomatic troponin release are randomized 1:1 to clopidogrel or placebo (300-mg loading dose, followed by 75 mg daily) in addition to standard medical treatment with aspirin. The primary efficacy end point is the composite of cardiovascular death, stroke, or severe ischemia of the coronary or peripheral arterial circulation leading to an intervention. The evaluation of long-term safety includes bleeding defined by TIMI criteria. Recruitment began early 2010. The trial will continue until 750 patients are included and followed for at least 12 months. SUMMARY DECREASE-VII is evaluating whether early postoperative dual antiplatelet therapy for patients developing asymptomatic cardiac ischemia after vascular surgery reduces cardiovascular events with a favorable safety profile.

Abstract
Cardiovascular event rates have been shown to increase substantially with the number of symptomatic disease locations. We sought to assess the risk profile, management and subsequent event rates of polyvascular disease patients. Consecutive outpatients were assessed for atherosclerotic risk factors and medications in the REACH Registry. A total of 19,117 symptomatic patients in Europe completed a 2-year follow-up: 77.2% with single arterial bed disease (coronary artery or cerebrovascular or peripheral arterial disease) and 22.8% with polyvascular disease (≥ 1 disease location). Polyvascular disease patients were older (68.5 ± 9.4 vs 66.3 ± 9.9 years, p < 0.0001), more often current or former smokers (64.9% vs 58.7%, p < 0.0001), and more often suffered from hypertension (59.5% vs 46.6%, p < 0.0001) and diabetes (34.5% vs 25.9%, p < 0.0001) than single arterial bed disease patients. Despite more intense medical therapy, risk factors (smoking, hypertension, low fasting glucose, and low fasting total cholesterol) were less often controlled in polyvascular disease patients. This was associated with substantially more events over 2 years compared with single arterial bed disease patients (cMACCE [cardiovascular death/non-fatal stroke/non-fatal MI] odds ratio, 1.63 [95% CI, 1.45—1.83], p < 0.0001). In conclusion, polyvascular disease patients have more cardiovascular risk factors, and the prognosis for these patients is significantly worse than for patients with single arterial bed disease. This suggests a need to improve detection and consequent medical treatment of polyvascular disease.

Abstract
Patients undergoing noncardiac surgery are at risk of adverse perioperative and long-term outcome. When considering a patient for noncardiac surgery, a careful preoperative clinical risk evaluation and subsequent risk-reduction strategies are essential to reduce postoperative complications. To assist physicians with decision making, clinical guidelines are developed. The aim of clinical guidelines is to improve patient care by providing recommendations about appropriate healthcare in specific circumstances. Development of clinical guidelines is an important component in improving the quality of care. By translating the best available scientific evidence into specific recommendations, guidelines can serve as a useful tool to achieve effective and efficient patient care. In 2009, the first European Society of Cardiology guidelines on perioperative care were developed. This decisionmaking process integrates clinical markers, early coronary evaluation, functional capacity, and the type of surgery involved.

Abstract
BACKGROUND The prognostic value of heart failure symptoms on postoperative outcome is well acknowledged in perioperative guidelines. The prognostic value of asymptomatic left ventricular (LV) dysfunction remains unknown. This study evaluated the prognostic implications of asymptomatic LV dysfunction in vascular surgery patients assessed with routine echocardiography. METHODS Echocardiography was performed preoperatively in 1,005 consecutive vascular surgery patients. Systolic LV dysfunction was defined as LV ejection fraction less than 50%. Ratio of mitral-peak velocity during early and late filling, pulmonary vein flow, and deceleration time was used to diagnose diastolic LV dysfunction. Troponin-T measurements and electrocardiograms were performed routinely perioperatively. Multivariate regression analyses evaluated the relation between LV function and the study endpoints, 30-day cardiovascular events, and long-term cardiovascular mortality. RESULTS Left ventricular dysfunction was diagnosed in 506 (50%) patients of which 80% were asymptomatic. In open vascular surgery (n = 649), both asymptomatic systolic and isolated diastolic LV dysfunctions were associated with 30-day cardiovascular events (odds ratios 2.3, 95% confidence interval [CI] 1.4-3.6 and 1.8, 95% CI 1.1-2.9, respectively) and long-term cardiovascular mortality (hazard ratios 4.6, 95% CI 2.4-8.5 and 3.0, 95% CI 1.5-6.0, respectively). In endovascular surgery (n = 356), only symptomatic heart failure was associated with 30-day cardiovascular events (odds ratio 1.8, 95% CI 1.1-2.9) and long-term cardiovascular mortality (hazard ratio 10.3, 95% CI 5.4-19.3). CONCLUSIONS This study demonstrated that asymptomatic LV dysfunction is predictive for 30-day and long-term cardiovascular outcome in open vascular surgery patients. These data suggest that preoperative risk stratification should include not only solely heart failure symptoms but also routine preoperative echocardiography to risk stratify open vascular surgery patients.
