ABSTRACT: Importance: Cardiovascular disease (CVD) is the most common cause of death among adults in the United States. Treatment to prevent CVD events by modifying risk factors is currently informed by the Framingham Risk Score, the Pooled Cohort Equations, or similar CVD risk assessment models. If current CVD risk assessment models could be improved by adding more risk factors, treatment might be better targeted, thereby maximizing the benefits and minimizing the harms. Objective: To update the 2009 US Preventive Services Task Force (USPSTF) recommendation on using nontraditional risk factors in coronary heart disease risk assessment. Evidence Review: The USPSTF reviewed the evidence on using nontraditional risk factors in CVD risk assessment, focusing on the ankle-brachial index (ABI), high-sensitivity C-reactive protein (hsCRP) level, and coronary artery calcium (CAC) score; the health benefits and harms of CVD risk assessment and treatment guided by nontraditional risk factors combined with the Framingham Risk Score or Pooled Cohort Equations compared with using either risk assessment model alone; and whether adding nontraditional risk factors to existing CVD risk assessment models improves measures of calibration, discrimination, and risk reclassification. Findings: The USPSTF found adequate evidence that adding the ABI, hsCRP level, and CAC score to existing CVD risk assessment models results in small improvements in discrimination and risk reclassification; however, the clinical meaning of these changes is largely unknown. Evidence on adding the ABI, hsCRP level, and CAC score to the Pooled Cohort Equations is limited. The USPSTF found inadequate evidence to assess whether treatment decisions guided by the ABI, hsCRP level, or CAC score, in addition to risk factors in existing CVD risk assessment models, leads to reduced incidence of CVD events or mortality. The USPSTF found adequate evidence to conceptually bound the harms of early detection and interventions as small. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of using the ABI, hsCRP level, or CAC score in risk assessment for CVD in asymptomatic adults to prevent CVD events. Conclusions and Recommendation: The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of adding the ABI, hsCRP level, or CAC score to traditional risk assessment for CVD in asymptomatic adults to prevent CVD events.

2 Review Isolated disease of the proximal left anterior descending artery comparing the effectiveness of percutaneous coronary interventions and coronary artery bypass surgery. 2008

Kapoor, John R / Gienger, Allison L / Ardehali, Reza / Varghese, Robin / Perez, Marco V / Sundaram, Vandana / McDonald, Kathryn M / Owens, Douglas K / Hlatky, Mark A / Bravata, Dena M. ·Department of Cardiology, Stanford University School of Medicine, California, USA. jkapoor@stanford.edu ·JACC Cardiovasc Interv · Pubmed #19463349.

ABSTRACT: OBJECTIVES: This study sought to systematically compare the effectiveness of percutaneous coronary intervention and coronary artery bypass surgery in patients with single-vessel disease of the proximal left anterior descending (LAD) coronary artery. BACKGROUND: It is uncertain whether percutaneous coronary interventions (PCI) or coronary artery bypass grafting (CABG) surgery provides better clinical outcomes among patients with single-vessel disease of the proximal LAD. METHODS: We searched relevant databases (MEDLINE, EMBASE, and Cochrane from 1966 to 2006) to identify randomized controlled trials that compared outcomes for patients with single-vessel proximal LAD assigned to either PCI or CABG. RESULTS: We identified 9 randomized controlled trials that enrolled a total of 1,210 patients (633 received PCI and 577 received CABG). There were no differences in survival at 30 days, 1 year, or 5 years, nor were there differences in the rates of procedural strokes or myocardial infarctions, whereas the rate of repeat revascularization was significantly less after CABG than after PCI (at 1 year: 7.3% vs. 19.5%; at 5 years: 7.3% vs. 33.5%). Angina relief was significantly greater after CABG than after PCI (at 1 year: 95.5% vs. 84.6%; at 5 years: 84.2% vs. 75.6%). Patients undergoing CABG spent 3.2 more days in the hospital than those receiving PCI (95% confidence interval: 2.3 to 4.1 days, p < 0.0001), required more transfusions, and were more likely to have arrhythmias immediately post-procedure. CONCLUSIONS: In patients with single-vessel, proximal LAD disease, survival was similar in CABG-assigned and PCI-assigned patients; CABG was significantly more effective in relieving angina and led to fewer repeat revascularizations.

ABSTRACT: BACKGROUND: Coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are alternative treatments for multivessel coronary disease. Although the procedures have been compared in several randomised trials, their long-term effects on mortality in key clinical subgroups are uncertain. We undertook a collaborative analysis of data from randomised trials to assess whether the effects of the procedures on mortality are modified by patient characteristics. METHODS: We pooled individual patient data from ten randomised trials to compare the effectiveness of CABG with PCI according to patients' baseline clinical characteristics. We used stratified, random effects Cox proportional hazards models to test the effect on all-cause mortality of randomised treatment assignment and its interaction with clinical characteristics. All analyses were by intention to treat. FINDINGS: Ten participating trials provided data on 7812 patients. PCI was done with balloon angioplasty in six trials and with bare-metal stents in four trials. Over a median follow-up of 5.9 years (IQR 5.0-10.0), 575 (15%) of 3889 patients assigned to CABG died compared with 628 (16%) of 3923 patients assigned to PCI (hazard ratio [HR] 0.91, 95% CI 0.82-1.02; p=0.12). In patients with diabetes (CABG, n=615; PCI, n=618), mortality was substantially lower in the CABG group than in the PCI group (HR 0.70, 0.56-0.87); however, mortality was similar between groups in patients without diabetes (HR 0.98, 0.86-1.12; p=0.014 for interaction). Patient age modified the effect of treatment on mortality, with hazard ratios of 1.25 (0.94-1.66) in patients younger than 55 years, 0.90 (0.75-1.09) in patients aged 55-64 years, and 0.82 (0.70-0.97) in patients 65 years and older (p=0.002 for interaction). Treatment effect was not modified by the number of diseased vessels or other baseline characteristics. INTERPRETATION: Long-term mortality is similar after CABG and PCI in most patient subgroups with multivessel coronary artery disease, so choice of treatment should depend on patient preferences for other outcomes. CABG might be a better option for patients with diabetes and patients aged 65 years or older because we found mortality to be lower in these subgroups.
