Prévention primaire Avantages et risques de AAS selon le risque coronarien à 5 ans
.* Estimates based on 1000 patients receiving aspirin for 5 years and a relative riskreduction of 28% for coronary heart disease (CHD) events in those who receivedaspirin. CHD events nonfatal acute myocardial infarction, fatal CHD. Valuesin parentheses are 95% CIs. The following caveats apply to these estimates.1) Reduction in CHD risk may be smaller in women, but data are limited. 2) Forelderly persons, absolute risk for hemorrhagic stroke and major gastrointestinalbleeding may be two to three times higher in patients receiving aspirin; however,aspirin may provide benefit in elderly persons by reducing ischemic stroke, theincidence of which increases with age. Aspirin does not appear to improve incidenceof ischemic stroke in middle-aged patients. 3) Risk for hemorrhagic strokemay be greater with larger doses of aspirin. 4) Aspirin may not prevent myocardialinfarction in patients with uncontrolled hypertension (systolic blood pressure 150 mm Hg). 5) Long-term outcomes ( 5–7 years) are unknown. 6) Patients athigh risk ( 10% 5-year risk) may derive greater benefit from aspirin, including a15% to 20% reduction in ischemic stroke and all-cause mortality, because theirrisk is similar to that of patients with known CHD.

Pooled data from aspirin trials in secondary prevention settings1 and a single trial in diabetic patients with and without coronary heart disease2 suggest that diabetic patients benefit as much or more from aspirin as non diabetic patients. ETDRS Investigators.Similarly, although antiplatelet therapy was associﾁｩated with only a nonﾁｩsignificant 7% (8%) proportionalreduction in serious vascular events among patientswith diabetes mellitus (but, predominantly, no historyof myocardial infarction or stroke), these results do notprovide reliable evidence of a lack of worthwhilebenefit in such patients. Indeed, taken as a whole theyindicate the converse, although direct evidence fromfurther randomised trials of antiplatelet therapyamong diabetic patients would still be helpful.However, our previous finding that antiplatelet therapyis similarly effective among patients with preﾁｩexistingsymptomatic vascular disease who do and do not havediabetes1 suggests that aspirin is likely to be effective forthe primary prevention of vascular events amongdiabetic patients. Furthermore, there is now goodevidence that antiplatelet therapy is not associated withany special risks (such as bleeding in the eye) inpatients with diabetes.29 Hence, it may be appropriateto consider antiplatelet therapy in diabetic patientswho are at substantial risk of a first vascular event (suchas those with proteinuria)45 and nonﾁｩdiabetic patientsat high risk because of preﾁｩexisting vascular disease,even if there is no direct evidence of benefit (as forpatients undergoing coronary artery surgery or thosewith heart failure46), provided that there are no specialrisks of bleeding that might outweigh the benefit. Thus,these findings can reasonably be extrapolated to a farwider range of high risk patients than those studied,but the further the extrapolation goes, the more desirﾁｩable it is to have direct evidenceﾑfor example, forpatients with renal disease, who are at high risk ofmyocardial infarction and ischaem 1.

Clopidogrel: amplified benefit over ASA In CAPRIE patients with a history of diabetes

En prenant soin de pas compter deux fois les mêmes événements, Bhatt et al. ont compilé les taux d’événements chez les patients diabétiques appartenant aux deux branches de traitement. Chez les 1 952 patients diabétiques qui avaient été assignés de façon aléatoire au groupe recevant l’AAS, le taux d’événements annuel s’élevait à 17,7 %, contre 15,6 % chez les 1 914 patients assignés au groupe recevant le clopidogrel (p = 0,042). Les chercheurs ont trouvé que la réduction du risque absolu obtenue avec le clopidogrel était supérieure chez les patients diabétiques recevant de l’insuline : le taux d’événements a été de 21,5 % avec l’AAS, contre 17,7 % avec le clopidogrel (p = 0,106). Dans un modèle multifactoriel incorporant les caractéristiques cliniques de départ, le traitement avec le clopidogrel a été associé de façon indépendante à une réduction du nombre de cas de mort vasculaire, d’IM, d’AVC et de réhospitalisation (pour saignements ou ischémie) chez des patients diabétiques (p = 0,032). Ceci équivaut à la prévention de quelque 38 accidents ischémiques importants de plus par 1 000 années-patients si le clopidogrel est utilisé au lieu de l’AAS. Référence Bhatt et al.

Am J Cardiol (United States), Sep , 90(6) p625-8 Following an ischemic event, diabetic patients have a higher rate of recurrence than patients without diabetes mellitus. 1–6 Patients with diabetes but without prior myocardial infarction (MI) have a risk of MI during follow-up that is similar to that of nondiabetic patients who have already had a prior MI. 7 The mechanisms for the heightened risk are multifactorial. 8 However, a greater thrombotic predisposition exists with diabetes, which is largely mediated by platelets. 9–13 Aspirin has been shown to have a modest benefit over placebo in reducing vascular events in patients with diabetes mellitus. 14 The intravenous antiplatelet agent abciximab has been found to be particularly efficacious in patients with diabetes who are undergoing percutaneous revascularization. 15,16 Platelet glycoprotein IIb/IIIa inhibitors, when used for acute coronary syndromes, appear to have their greatest benefit in diabetic patients. 17 The Clopidogrel versus Aspirin in Patients at Risk of Ischemic Events (CAPRIE) study randomized 19,185 patients with recent ischemic stroke, recent MI, or established peripheral arterial disease to the adenosine diphosphate (ADP) receptor antagonist clopidogrel or to aspirin. 18 An 8.7% relative risk reduction was seen in vascular death, MI, or ischemic stroke with use of clopidogrel.

Prev. MI 10.7% 42 Background Dual antiplatelet therapy with clopidogrel plus low-dose aspirin has not been studiedin a broad population of patients at high risk for atherothrombotic events. Methods We randomly assigned 15,603 patients with either clinically evident cardiovasculardisease or multiple risk factors to receive clopidogrel (75 mg per day) plus low-doseaspirin (75 to 162 mg per day) or placebo plus low-dose aspirin and followed themfor a median of 28 months. The primary efficacy end point was a composite ofmyocardial infarction, stroke, or death from cardiovascular causes. Results The rate of the primary efficacy end point was 6.8 percent with clopidogrel plus aspirinand 7.3 percent with placebo plus aspirin (relative risk, 0.93; 95 percent confidenceinterval, 0.83 to 1.05; P = 0.22). The respective rate of the principal secondary efficacyend point, which included hospitalizations for ischemic events, was 16.7 percent and17.9 percent (relative risk, 0.92; 95 percent confidence interval, 0.86 to 0.995; P = 0.04),and the rate of severe bleeding was 1.7 percent and 1.3 percent (relative risk, 1.25; 95percent confidence interval, 0.97 tο 1.61 percent; P = 0.09). The rate of the primaryend point among patients with multiple risk factors was 6.6 percent with clopidogreland 5.5 percent with placebo (relative risk, 1.2; 95 percent confidence interval, 0.91 to1.59; P = 0.20) and the rate of death from cardiovascular causes also was higher withclopidogrel (3.9 percent vs. 2.2 percent, P = 0.01). In the subgroup with clinically evidentatherothrombosis, the rate was 6.9 percent with clopidogrel and 7.9 percent withplacebo (relative risk, 0.88; 95 percent confidence interval, 0.77 to 0.998; P = 0.046). Conclusions In this trial, there was a suggestion of benefit with clopidogrel treatment in patientswith symptomatic atherothrombosis and a suggestion of harm in patients with multiplerisk factors. Overall, clopidogrel plus aspirin was not significantly more effectivethan aspirin alone in reducing the rate of myocardial infarction, stroke, or death fromcardiovascular causes.

Neuf mille deux cent quatre-vingt-dix-sept (9 297) patients exposés à un risque élevé (âgés de 55 ans ou plus) ayant des antécédents de maladie vasculaire (maladie coronarienne, accident vasculaire cérébral, artériopathie périphérique) ou présentant un diabète et un autre facteur de risque cardiovasculaire (hypertension, taux élevé de cholestérol total, faible taux de cholestérol HDL, tabagisme ou microalbuminurie documentée) ont reçu, au terme d’une randomisation, du ramipril (10 mg, 1 fois par jour par voie orale) ou un placebo de même apparence durant en moyenne 5 ans. Ont été exclus les patients qui présentaient une insuffisance cardiaque, une FEVG inférieure à 40 % ou une hypertension non maîtrisée. Le paramètre principal était composé des issues suivantes : infarctus du myocarde, AVC ou décès d’origine cardiovasculaire. Les paramètres secondaires étaient la mortalité toutes causes confondues, la nécessité de subir une revascularisation, l’hospitalisation pour cause d’angine instable ou d’insuffisance cardiaque, de même que les complications liées au diabète (nécessitant ou non une hospitalisation). L’aggravation de l’angine, l’arrêt cardiaque, l’insuffisance cardiaque (nécessitant ou non une hospitalisation), l’angine instable avec altérations visibles à l’ECG et l’apparition du diabète étaient d’autres issues à l’étude.

La fréquence des événements composant le paramètre principal a également été réduite de façon significative, soit de 20 % dans le cas de l’IM, de 32 % dans le cas de l’AVC et de 26 % dans le cas des décès d’origine cardiovasculaire. Parmi les autres événements dont la fréquence a été significativement réduite, mentionnons la mortalité totale, l’insuffisance cardiaque et les nouveaux cas de diabète.

Le ramipril a eu un effet protecteur évident et constant sur les critères de jugement primaire, tout comme sur chacun des éléments du critère de jugement primaire combiné. Ce qui n’apparaît pas sur la diapo, ce sont les effets bénéfiques constants dans l’ensemble des sous-groupes cliniques (diabète de type 1 par rapport au diabète de type 2, hommes par rapport aux femmes, microalbuminurie par rapport à l’absence de microalbuminurie, antécédents de maladie cardiovasculaire par rapport à l’absence d’antécédents de maladie cardiovasculaire, insulinothérapie par rapport à l’absence d’insulinothérapie). Ce qui n’apparaît pas également, c’est que l’abaissement de la tension artérielle par le ramipril était de 1,9 mm pour la tension systolique et de 3,3 mm pour la tension diastolique comparativement à une élévation de la tension systolique, de 0,55 mm et une chute de la tension diastolique de 2,3 mm dans le groupe placebo. Cette variation de la tension artérielle est beaucoup trop faible pour expliquer les effets bénéfiques qui ont été observés. C’est que, selon des études épidémiologiques, il faut une chute de tension systolique de 10 mm et de tension diastolique de 5 mm pour obtenir une réduction de 38 % des accidents vasculaires cérébraux et de 16 % des maladies coronariennes. Dans cette étude, des réductions du risque > 20 % pour chacun de ces critères de jugement ont été observées pour des effets bien plus modestes sur la tension artérielle. p = 0,007 37 % -40 p = 0,0001 Hope Study Investigators.

Fin de l’étude HOPE 0,30 70% sur IECA 0,25 Placebo 0,20 Étude HOPE (paramètres d’évaluation combinés) Proportion de patients Ramipril 0,15 0,10 p = 0,0002 0,05 Étude HOPE-TOO (Heart Outcomes Prevention Evaluation – The Ongoing Outcomes) Dans le cadre de l’étude complémentaire HOPE-TOO, patients ont fait l’objet d’un suivi (dans 174 centres). On a mis fin au traitement à l’insu et on a conseillé aux patients de prendre un inhibiteur de l’ECA. Les investigateurs se sont intéressés aux mêmes issues cardiovasculaires que celles dont on a tenu compte dans l’étude HOPE. La durée du suivi prolongé a été de 2,6 ans. Emploi d’un inhibiteur de l’ECA durant la phase complémentaire : - groupe ramipril de l’étude HOPE (n = 2317) : 72 % - groupe placebo de l’étude HOPE (n = 2211) : 68 % Plus de 90 % des participants à l’étude HOPE-TOO ont eu recours au ramipril. Durant le suivi postérieur à l’étude, les patients ayant reçu le ramipril présentaient un risque relatif d’IM 19 % moins élevé (IC de 95 %, de 0,65 à 1,01), un risque relatif de revascularisation 16 % moins élevé (IC de 95 %, de 0,70 à 0,99) et un risque relatif 34 % moins élevé de recevoir un nouveau diagnostic de diabète (IC de 95 %, de 0,46 à 0,95). Des réductions semblables du risque relatif d’événements vasculaires ont été observées durant et après la phase active de l’étude, et ce, peu importe le risque initial (risque relatif de 0,76, 0,89 et 0,83, respectivement, chez les patients exposés à un risque faible, moyen et élevé) ou les traitements auxiliaires utilisés (risque relatif de 0,90 pour l’AAS, de 0,76 pour les bêtabloquants et de 0,84 pour les hypolipidémiants). Conclusions Les bienfaits du ramipril se sont maintenus durant le suivi postérieur à l’étude en ce qui a trait aux décès d’origine cardiovasculaire, aux AVC et à l’hospitalisation pour cause d’insuffisance cardiaque.

For persons with diabetes and albuminuria (urinary albumin excretion rates over 30 mg/day) an ACE inhibitor or an angiotensin II receptor blocker is recommended as initial therapy (Grade A). If blood pressure remains greater than 130/80 mmHg despite lifestyle interventions and an ACE inhibitor or angiotensin II receptor blocker, then addition of one or more of a thiazide diuretic, long-acting calcium channel blocker, or use of ACE inhibitor and angiotensin II receptor blocker in combination can be considered (Grade D). If an ACE inhibitor and angiotensin II receptor blocker cannot be tolerated, a cardioselective beta-adrenergic blocker (Grade B), long acting calcium channel blocker (Grade C), or thiazide diuretic can be substituted (Grade B). Comment: We have recommended that this be changed, but not on the basis of ALLHAT. Sentence 2 in the version that was approved implies that use of an ACE inhibitor - ARB combination should be tried ahead of all other add-on and combination options. There is no evidence to support this position and it was not the original intent of the Diabetic subcommittee to indicate a preference for ACE inhibitor/ARB combination therapy over any other strategy. We think the modified wording more clearly indicates this.

Blood pressure response in the INSIGHT study Diabetic vs non-diabetic patients
5669 pts AbstractﾑThe aim of our investigation was to determine whether the presence of additional risk factors or type ofhypertension (diastolic or isolated systolic) influences blood pressure (BP) response to treatment. The InternationalNifedipine GITS Study: Intervention as a Goal in Hypertension Treatment (INSIGHT) study is a double-blindedoutcome comparison of calcium channel blockade with diuretics in high-risk patients aged 55 to 80 years. Dynamicrandomization between nifedipine once daily and hydrochlorothiazide/amiloride was performed to ensure thatapproximately equal numbers of patients in the 2 groups had each of the major cardiovascular risk factors. Patients withisolated systolic hypertension were also separately randomized. Atenolol or enalapril was the mandatory second-linedrug. In 5669 patients who completed the 18-week titration, BP fell from /9969 mm Hg (mean6SD) whilereceiving placebo to /8267 mm Hg. Twenty-six percent of patients required 2 drugs, and 4% required 3 drugs.Patients with diabetes were the most resistant to treatment, requiring second and third drugs 40% and 100% morefrequently than patients without diabetes and achieving marginally the highest final BP, for any risk group, of141613/8268 mm Hg. Age, smoking, gender, hypercholesterolemia, left ventricular hypertrophy, and existingatherosclerosis had little (,1 mm Hg) or no influence on BP at the end of titration, but all except smoking slightlyreduced the initial response of either systolic or diastolic BP. Patients with isolated systolic hypertension were slightlymore responsive than average to treatment. Our findings suggest that in patients at high absolute risk of cardiovascularcomplications from hypertension, the risk factors themselves do not prevent the recommended BP targets frombeing achieved.

Maîtrise glycémique pour la protection vasculaire : Une fois tous les patients sous IECA, AAS et maîtrise des lipides (statine) 5 Infarctus du myocarde mortel ou non : ACD 2003 : CIBLES GLYCÉMIQUES A1c  7 % chez la plupart des patients A1c  6 % quand cela est possible en toute sécurité Diminution de 14 % pour chaque % de réduction de l’A1C p < 0,0001 Rapport de risque 1 0,5 L’étude UKPDS a fait ressortir une relation linéaire directe entre les valeurs de l’A1c moyenne et la fréquence des infarctus du myocarde : chaque pourcentage de réduction (absolue) de l’A1c moyenne était associé à une diminution de 14 % de la fréquence des IM. L’étude UKPDS, une recherche observationnelle prospective, a été réalisée dans 23 cliniques d’hôpitaux d’Angleterre, d’Écosse et d’Irlande du Nord. En tout, participants, affectés ou non à un traitement au terme d’une randomisation, ont été inclus dans les analyses de la fréquence; de ce nombre, ont été inclus dans les analyses du risque relatif. PARAMÈTRES D’ÉVALUATION : Paramètre principal composé d’issues cliniques prédéfinies : toute issue ou mortalité liée au diabète et mortalité toutes causes confondues. Paramètre secondaire composé des événements suivants : infarctus du myocarde, AVC, amputation (incluant la mortalité attribuable à une artériopathie périphérique) et maladie microvasculaire (principalement photocoagulation de la rétine). Paramètres simples : insuffisance cardiaque non mortelle et extraction de cataracte. La diminution du risque associée à chaque pourcentage de réduction de l’A1c moyenne mise à jour a été rectifiée en fonction des facteurs confusionnels ayant pu être présents au moment du diagnostic de diabète. RÉSULTATS : La fréquence des complications cliniques était associée de manière significative à la glycémie. Chaque pourcentage de réduction de l’A1c moyenne mise à jour était associé à une diminution de 21 % du risque que survienne n’importe laquelle des issues ayant trait au diabète (intervalle de confiance à 95 %, de 17 à 24 %, p < 0,0001), de 21 % pour la mortalité associée au diabète (de 15 à 27 %, p < 0,0001), de 14 % pour les infarctus du myocarde (de 8 à 21 %, p < 0,0001) et de 37 % pour les complications microvasculaires (de 33 à 41 %, p < 0,0001). Aucun seuil de risque n’a été observé, quelle que soit l’issue. CONCLUSIONS : Chez les patients atteints de diabète de type 2, le risque de complications diabétiques était étroitement associé à une hyperglycémie antérieure. Toute diminution de la valeur de l’A1c est susceptible de réduire le risque de complications, le plus faible risque étant associé aux valeurs de l’A1c se situant dans la plage normale (< 6,0 %).

The purpose of this study was to assess the effect of 10 mg of atorvastatin versus placebo on CVD prevention in subjects with type 2 diabetes and LDL cholesterol levels below contemporary guideline targets. RESEARCH DESIGN AND METHODS: Subjects were randomly assigned to receive 10 mg of atorvastatin or placebo in a 4-year, double-blind, parallel-group study. The composite primary end point comprised cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, recanalization, coronary artery bypass surgery, resuscitated cardiac arrest, and worsening or unstable angina requiring hospitalization. RESULTS: A total of 2,410 subjects with type 2 diabetes were randomized. Mean LDL cholesterol reduction in the atorvastatin group over 4 years was 29% versus placebo (P < ). When we compared atorvastatin versus placebo, composite primary end point rates were 13.7 and 15.0%, respectively (hazard ratio 0.90 [95% CI ]). In the subset of 1,905 subjects without prior myocardial infarction or interventional procedure, 10.4% of atorvastatin- and 10.8% of placebo-treated subjects experienced a primary end point (0.97 [ ]). In the 505 subjects with prior myocardial infarction or interventional procedure, 26.2% of atorvastatin- and 30.8% of placebo-treated subjects experienced a primary end point (0.82 [ ]). Relative risk reductions in fatal and nonfatal myocardial infarction were 27% overall (P = 0.10) and 19% (P = 0.41) and 36% (P = 0.11) for subjects without and with prior myocardial infarction or interventional procedure, respectively. CONCLUSIONS: Composite end point reductions were not statistically significant. This result may relate to the overall study design, the types of subjects recruited, the nature of the primary end point, and the protocol changes required because of changing treatment guidelines. For these reasons, the results of the Atorvastatin Study for Prevention of Coronary Heart Disease Endpoints in Non-Insulin-Dependent Diabetes Mellitus (ASPEN) did not confirm the benefit of therapy but do not detract from the imperative that the majority of diabetic patients are at risk of coronary heart disease and deserve LDL cholesterol lowering to the currently recommended targets.

Effects of long-term fenofibrate therapy on CV events
Background Patients with type 2 diabetes mellitus are at increased risk of cardiovascular disease, partly owing todyslipidaemia, which can be amenable to fibrate therapy. We designed the Fenofibrate Intervention and Event Loweringin Diabetes (FIELD) study to assess the effect of fenofibrate on cardiovascular disease events in these patients.Methods We did a multinational, randomised controlled trial with 9795 participants aged 50ﾐ75 years, with type 2diabetes mellitus, and not taking statin therapy at study entry. After a placebo and a fenofibrate run-in phase, werandomly assigned patients (2131 with previous cardiovascular disease and 7664 without) with a total-cholesterolconcentration of 3�0ﾐ6�5 mmol/L and a total-cholesterol/HDL-cholesterol ratio of 4�0 or more or plasma triglyceride of1�0ﾐ5�0 mmol/L to micronised fenofibrate 200 mg daily (n=4895) or matching placebo (n=4900). Our primary outcomewas coronary events (coronary heart disease death or non-fatal myocardial infarction); the outcome for prespecifiedsubgroup analyses was total cardiovascular events (the composite of cardiovascular death, myocardial infarction, stroke,and coronary and carotid revascularisation). Analysis was by intention to treat. The study was prospectively registered(number ISRCTN ).Findings Vital status was confirmed on all but 22 patients. Averaged over the 5 yearsﾕ study duration, similar proportionsin each group discontinued study medication (10% placebo vs 11% fenofibrate) and more patients allocated placebo(17%) than fenofibrate (8%; p!0�0001) commenced other lipid treatments, predominantly statins. 5�9% (n=288) ofpatients on placebo and 5�2% (n=256) of those on fenofibrate had a coronary event (relative reduction of 11%; hazardratio [HR] 0�89, 95% CI 0�75ﾐ1�05; p=0�16). This finding corresponds to a significant 24% reduction in non-fatalmyocardial infarction (0�76, 0�62ﾐ0�94; p=0�010) and a non-significant increase in coronary heart disease mortality(1�19, 0�90ﾐ1�57; p=0�22). Total cardiovascular disease events were significantly reduced from 13�9% to 12.5% (0�89,0�80ﾐ0�99; p=0�035). This finding included a 21% reduction in coronary revascularisation (0�79, 0�68ﾐ0�93; p=0�003).Total mortality was 6�6% in the placebo group and 7�3% in the fenofibrate group (p=0�18). Fenofibrate was associatedwith less albuminuria progression (p=0�002), and less retinopathy needing laser treatment (5�2% vs 3�6%, p=0�0003).There was a slight increase in pancreatitis (0�5% vs 0�8%, p=0�031) and pulmonary embolism (0�7% vs 1�1%,p=0�022), but no other significant adverse effects.Interpretation Fenofibrate did not significantly reduce the risk of the primary outcome of coronary events. It did reducetotal cardiovascular events, mainly due to fewer non-fatal myocardial infarctions and revascularisations. The higher rateof starting statin therapy in patients allocated placebo might have masked a moderately larger treatment benefit. Lancet 2005 366:

Theprimary outcome was major coronary events defined ascoronary heart disease death, non-fatal myocardial infarction,or myocardial revascularisation procedures. Results Twelve studies were included. Lipid lowering drugtreatment was found to be at least as effective in diabeticpatients as in non-diabetic patients. In primary prevention, therisk reduction for major coronary events was 21% (95%confidence interval 11% to 30%; P < ) in diabetic patientsand 23% (12% to 33%; P = ) in non-diabetic patients. Insecondary prevention, the corresponding risk reductions were21% (10% to 31%; P = ) and 23% (19% to 26%;P ! ). However, the absolute risk difference was threetimes higher in secondary prevention. When results wereadjusted for baseline risk, diabetic patients benefited more inboth primary and secondary prevention. Blood lipids werereduced to a similar degree in both groups.Conclusions The evidence that lipid lowering drug treatment(especially statins) significantly reduce cardiovascular risk indiabetic and non-diabetic patients is strong and suggests thatdiabetic patients benefit more, in both primary and secondaryprevention.

Watsky, MD;Rich Anziano, MS; Karen R. Reeves, MD; for the Varenicline Study GroupBackground: Currently available smoking cessationtherapies have limited success rates. Varenicline tartrateis a novel, selective nicotinic receptor partial agonistdeveloped specifically for smoking cessation. Thisstudy evaluated the efficacy, tolerability, and safety of 3varenicline doses for smoking cessation. Bupropion hydrochloridewas included as an active control.Methods: A phase 2, multicenter, randomized, doubleblind,placebo-controlled study of healthy smokers (18-65years old). Subjects were randomized to varenicline tartrate,0.3 mg once daily (n=128), 1.0 mg once daily(n=128), or 1.0 mg twice daily (n=127), for 6 weeks plusplacebo for 1 week; to 150-mg sustained-release bupropionhydrochloride twice daily (n=128) for 7 weeks; orto placebo (n=127) for 7 weeks.Results: During the treatment phase, the continuous quitrates for any 4 weeks were significantly higher for vareniclinetartrate, 1.0 mg twice daily (48.0%; P .001) and 1.0mgonce daily (37.3%; P .001), than for placebo (17.1%).Thebupropionratewas33.3%(P=.002vsplacebo).Thecarbonmonoxideﾐconfirmedcontinuous quit ratesfromweek4toweek52were significantly higher in the varenicline tartrate,1.0mgtwice daily, group compared with the placebogroup(14.4%vs4.9%;P=.002).Thebupropionratewas6.3%(P=.60 vs placebo).

Lifestyle Modification Low Cardiorespiratory Fitness and Physical Inactivity as Predictors of Mortality in Men with Type 2 Diabetes FIT UNFIT Background: Although physical activity is recommendedas a basic treatment for patients with diabetes, its longtermassociation with mortality in these patients is unknown.Objective: To evaluate the association of low cardiorespiratoryfitness and physical inactivity with mortality in menwith type 2 diabetes.Design: Prospective cohort study.Setting: Preventive medicine clinic.Patients: 1263 men (50 ! 10 years of age) with type 2diabetes who received a thorough medical examinationbetween 1970 and 1993 and were followed for mortalityup to 31 December 1994.Measurements: Cardiorespiratory fitness measured by amaximal exercise test, self-reported physical inactivity atbaseline, and subsequent death determined by using theNational Death Index.Results: During an average follow-up of 12 years, 180patients died. After adjustment for age, baseline cardiovasculardisease, fasting plasma glucose level, high cholesterollevel, overweight, current smoking, high blood pressure,and parental history of cardiovascular disease, men inthe low-fitness group had an adjusted risk for all-causemortality of 2.1 (95% CI, 1.5 to 2.9) compared with fit men.Men who reported being physically inactive had an adjustedrisk for mortality that was 1.7-fold (CI, 1.2-fold to2.3-fold) higher than that in men who reported beingphysically active.Conclusions: Low cardiorespiratory fitness and physicalinactivity are independent predictors of all-cause mortalityin men with type 2 diabetes. Physicians should encouragepatients with type 2 diabetes to participate in regularphysical activity and improve cardiorespiratory fitness. Wein M et al. Ann Intern Med 2000; 132:
