An empirically derived short form of the Hypoglycaemia Fear Survey II.

AIMS: To develop an empirically derived short version of the Hypoglycaemia Fear Survey II that still accurately measures fear of hypoglycaemia. METHODS: Item response theory methods were used to generate an 11-item version of the Hypoglycaemia Fear Survey from a sample of 487 people with Type 1 or Type 2 diabetes mellitus. Subsequently, this scale was tested on a sample of 2718 people with Type 1 or insulin-treated Type 2 diabetes taking part in DIALOG, a large observational prospective study of hypoglycaemia in France. RESULTS: The short form of the Hypoglycaemia Fear Survey II matched the factor structure of the long form for respondents with both Type 1 and Type 2 diabetes, while maintaining adequate internal reliability on the total scale and all three subscales. The two forms were highly correlated on both the total scale and each subscale (Pearson's R > 0.89). CONCLUSIONS: The short form of the Hypoglycaemia Fear Survey II is an important first step in more efficiently measuring fear of hypoglycaemia. Future prospective studies are needed for further validity testing and exploring the survey's applicability to different populations.

Bypassing the emergency room reduces delays and mortality in ST elevation myocardial infarction: the USIC 2000 registry.

OBJECTIVE: To study the impact on outcomes of direct admission versus emergency room (ER) admission in patients with ST-segment elevation myocardial infarction (STEMI) DESIGN: Nationwide observational registry of STEMI patients SETTING: 369 intensive care units in France. INTERVENTIONS: Patients were categorised on the basis of the initial management pathway (direct transfer to the coronary care unit or catheterisation laboratory versus transfer via the ER). MAIN OUTCOME MEASURES: Delays between symptom onset, admission and reperfusion therapy. Mortality at five days and one year. RESULTS: Of 1204 patients enrolled, 66.9% were admitted direct and 33.1% via the ER. Bypassing the ER was associated with more frequent use of reperfusion (61.7% v 53.1%; p = 0.001) and shorter delays between symptom onset and admission (244 (interquartile range 158) v 292 (172) min; p < 0.001), thrombolysis (204 (150) v 258 (240) min; p < 0.01), hospital thrombolysis (228 (156) v 256 (227) min, p = 0.22), and primary percutaneous coronary intervention (294 (246) v 402 (312) min; p < 0.005). Five day mortality rates were lower in patients who bypassed the ER (4.9% v 8.6%; p = 0.01), regardless of the use and type of reperfusion therapy. After adjusting for the simplified Thrombolysis in Myocardial Infarction (TIMI) risk score, admission via the ER was an independent predictor of five day mortality (odds ratio 1.67, 95% confidence interval 1.01 to 2.75). CONCLUSIONS: In this observational analysis, bypassing the ER was associated with more frequent and earlier use of reperfusion therapy, and with an apparent survival benefit compared with admission via the ER.

Insulin initiation in type 2 diabetic patients admitted in hospital in France and follow-up at 1 year.

OBJECTIVES AND METHODS: The IDAHO 2 epidemiological survey was conducted in departments of diabetology in insulin-naïve type 2 diabetics for whom insulin was initiated. The objective was to assess the patients' profile, the treatments proposed during hospital stay and after one year. RESULTS: 797 patients were analysed. Their characteristics were: age 64+/-12 years, 49% males, weight: 78+/-17 kg, BMI: 29+/-6 kg/m2, diabetes duration 11 years, prevalence of complications: 68%, fasting blood glucose 13+/-6 mmol/l, HbA1c: 10+/-2.2%; treatment prior to insulin comprised: at least 2 OHA: 71% of cases, one: 21%, no OAD: 8%. At hospital discharge, 54% of the patients used basal insulin. After 1 year, 670 continued on insulin. The insulin initiation was accompanied by a decrease in the FBG level (baseline: 13+/-6 mmol/l; final: 8.5+/-2.75 mmol/l; P<0.0001) and a HbA1c improvement (baseline: 10+/-2.2%; final: 7.9+/-1.4%; P<0.0001). This was observed du-ring the first 6 months (HbA1c: 7.8%, P<0.0001 versus baseline). 80% of the patients remained on the same insulin regimen after 1 year: 35% had 1 injection/day, 44% had 2, 12% had 3 and 9% had a complex regimen. The weight gain, the final daily dose and hypoglycaemias increased with the number of injections. The mean daily insulin dose was 33 U/day (24 U with 1 injection/day). CONCLUSION: The IDAHO study shows that insulin is effective in type 2 diabetics however, management is inadequate with insulin therapy being initiated too late and at doses which are low after one year.

High risk hypertensives: pre-hospital management of acute myocardial infarction--results from the French nationwide registry USIC 2000.

OBJECTIVE: To assess the use of mobile coronary care units (MCU) in hypertensive patients previously treated for cardiovascular diseases in comparison with those with no history of cardiovascular disease and to estimate the influence of the use of MCU on cardiovascular outcome in this population. PATIENTS: We used a nationwide prospective registry of all patients admitted for AMI in French intensive care units in 2000. Patients without history of hypertension or patients admitted with pulmonary oedema or cardiogenic shock were excluded. Men (N = 514) and women (N = 291) were analysed separately. RESULTS: The proportion of patients with history of myocardial infarction, peripheral artery disease and stroke was not significantly higher in subjects who used physician-staffed MCU as compared with patients with no history of myocardial infarction, peripheral artery disease or stroke. In each sex, revascularization (pre hospital fibrinolysis, in hospital fibrinolysis or coronary angioplasty) were more frequent in patients who used MCU. Also, one year cardiovascular mortality was lower in men who used MCU. CONCLUSION: Known high risk hypertensive patients did not use physician-staffed MCU more than subjects free of such condition. Education of hypertensive patients at risk during routine visits is required to increase of the use of physician-staffed MCU in case of symptoms suggestive of AMI.

Major impact of admission glycaemia on 30 day and one year mortality in non-diabetic patients admitted for myocardial infarction: results from the nationwide French USIC 2000 study.

OBJECTIVE: To analyse the short and long term prognostic significance of admission glycaemia in a large registry of non-diabetic patients with acute myocardial infarction. METHODS: Assessment of short and long term prognostic significance of admission blood glucose in a consecutive population of 1604 non-diabetic patients admitted to intensive care units in France in November 2000 for a recent (

[Management of patients admitted for acute myocardial infarction in France from 1995 to 2000: time to admission dependent improvement in outcome]. / Prise en charge de l'infarctus du myocarde en France dans les études USIK 1995 et USIC 2000: amélioration pronoslique et rôle du délai d'admission.

The in-hospital management and short- and long-term outcomes was assessed in 2 registries of consecutive patients admitted for acute myocardial infarction, 5 years apart, in France. The 2000 cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Time to admission was actually longer in 2000 than in 1995 (median 5.25 hours vs 4.00 hours). Overall, reperfusion therapy was used in 43% of the patients in both registries. However, the use of reperfusion therapy increased from 1995 to 2000 in patients admitted within 6 hours of symptom onset (64 vs 58%), with an increasing use of primary angioplasty (from 12 to 30%). Five-day mortality significantly improved from 7.7 to 6.1% (p < 0.03) and one-year survival was also less in the most recent period (85 vs 81%, p < 0.01). Multivariate analyses showed that the period of inclusion (2000 vs 1995) was an independent predictor of both short- and long-term mortality in patients admitted within 6 hours of symptom onset. Thus, in the real world setting, a continued decline in one-year mortality was observed in patients admitted to intensive care units for recent acute myocardial infarction, especially for patients admitted early. This goes along with a shift in reperfusion therapy towards a broader use of primary angioplasty, and with an increased use of the early prescription of recognised secondary prevention medications.

Electronic pill-boxes in the evaluation of oral hypoglycemic agent compliance.

OBJECTIVE: To compare compliance in type 2 diabetic patients treated with glimepiride once daily or glibenclamide twice to three times daily. METHODS: Poorly controlled type 2 diabetic patients aged 35-65 years were randomized to glimepiride 1 mg once daily or to glibenclamide 1.25 mg twice daily. During initial titration, doses ranged from 1 to 6 mg once daily (glimepiride) and from 1.25 mg twice daily to 5 mg 3 times daily (glibenclamide) to achieve fasting blood glucose < 126 mg/dL. The final titration phase doses were continued during the maintenance phase. Both treatments were packed in electronic pill-boxes fitted with a microprocessor to record dates and times of each opening. Compliance was assessed in terms of mean daily compliance (MDC) and the ratio of days with adequate compliance (DAC). Glycemic control was assessed in terms of the adjusted mean final HbA1c, and the incidence of hypoglycemia. Patient satisfaction was evaluated using the Diabetes Treatment Satisfaction Questionnaire. RESULTS: Compliance over the whole study was generally good, but the MDC was significantly better with glimepiride (87+/-16%) than with glibenclamide (80+/-17%;P < 0.0001). The ratios of DAC for glimepiride and glibenclamide were 87+/-16% and 67+/-24% respectively (P < 0.0001). The adjusted final HbA1c, and the incidence of hypoglycemia were similar in the two groups. Treatment satisfaction on the DTSQc was greater with glimepiride than with glibenclamide (P = 0.0034). CONCLUSIONS: Patient compliance and treatment satisfaction with once-daily glimepiride were significantly better than with glibenclamide 2 to 3 times daily.

Detection of masked hypertension by home blood pressure measurement: is the number of measurements an important issue?

BACKGROUND: Office blood pressure (OBP) and home blood pressure (HBP) enable the identification of patients with masked hypertension. Masked hypertension is defined by normal OBP and high HBP and is known as a pejorative cardiovascular risk factor. OBJECTIVE: The objective was to evaluate in the SHEAF study the influence of the number of office or home blood pressure measurements on the classification of patients as masked hypertensives. METHODS: Patients with OBP <140/90 mmHg (mean of six values: three measurements at two separate visits, V1 and V2) and HBP >135/85 mmHg (mean of all valid measurements performed over a 4-day period) were the masked hypertensive reference group. The consistency of the classification was evaluated by using five definitions of HBP values (mean of the 3, 6, 9, 12 and 15 first measurements) and two definitions of OBP values (mean of three measurements at V1 and mean of three measurements at V2). RESULTS: Among the 4939 treated hypertensives included in the SHEAF study, 463 (9.4%) were classified as masked hypertensives (reference group). By decreasing the number of office or home measurements, the prevalence of masked hypertension ranged from 8.9-12.1%. The sensitivity of the classification ranged from 94-69% therefore 6-31% of the masked hypertensives were not detected. The specificity ranged from 98-94% therefore 1-6% of patients were wrongly classified as masked hypertensives. CONCLUSION: A limited number of home and office BP measurements allowed the detection of masked hypertension with a high specificity and a low sensitivity. A sufficient number of measurements (three measurements at two visits for OBP and three measurements in the morning and in the evening over 2 days for HBP) are required to diagnose masked hypertension.

Management and in-hospital outcome of patients with acute myocardial infarction admitted to intensive care units at the turn of the century: results from the French nationwide USIC 2000 registry.

OBJECTIVE: To assess actual practices and in-hospital outcome of patients with acute myocardial infarction on a nationwide scale. METHODS: Of 443 intensive care units in France, 369 (83%) prospectively collected data on all cases of infarction (within < 48 hours of symptom onset) in November 2000. RESULTS: 2320 patients (median age 68 years, 73% men) were included, of whom 83% had ST segment elevation infarction (STEMI). Patients without STEMI were older and had a more frequent history of cardiovascular disease. Median time to admission was 5.0 hours for patients with and 6.5 hours for those without STEMI. Reperfusion therapy was used for 53% of patients with STEMI (thrombolysis 28%, primary angioplasty 25%). In-hospital mortality was 8.7% (5.5% of patients without and 9.3% of those with STEMI). Multivariate analysis found that age, Killip class, lower blood pressure, higher heart rate on admission, anterior location of infarct, STEMI, diabetes mellitus, previous stroke, and no current smoking independently predicted in-hospital mortality. At hospital discharge, 95% received antiplatelet agents, 75% received beta blockers, and over 60% received statins. Angiotensin converting enzyme inhibitors were prescribed for 40% of the patients without and 52% of those with ST elevation. CONCLUSIONS: This nationwide registry, including all types of centres irrespective of their size and experience, shows continued improvement in patient care and outcomes. Time from symptom onset to admission, however, has not improved in recent years and reperfusion therapy is used for just over 50% of patients with STEMI, with an increasing use of primary angioplasty.

[Evolution of the management and outcomes of patients admitted for acute myocardial infarction in France from 1995 to 2000: data from the USIK 1995 and USIC 2000 nationwide registries]. / Evolution de la prise en charge et du pronostic de l'infarctus du myocarde en France entre 1995 et 2000: résultats des études USIK 1995 et USIC 2000.

We assessed the in-hospital management and short- and long-term outcomes of two series of patients admitted for acute myocardial infarction, 5 years apart, in France. The most recent cohort was younger and with a less frequent history of cardiac diseases, but was more often diabetic and with anterior infarcts. Five-day mortality significantly improved from 7.7% to 6.1% (P < 0.03) and 1-year survival was also less in the most recent period (15% versus 19%, P < 0.01). Multivariate analyses showed that the period of inclusion (2000 versus 1995) was an independent predictor of both short- and long-term mortality. In analyses restricted to the patients who were alive by day 5, initial treatment with statins was associated with a 38% decrease in the risk of death at 1 year. Likewise, in patients with left ventricular ejection fraction < or = 35%, the early prescription of ACE inhibitors was associated with a 41% reduction in the risk of 1-year mortality. Thus, in the real world setting, a continued decline in 1-year mortality is observed in patients admitted to intensive care units for recent acute myocardial infarction. This goes along with a shift in reperfusion therapy towards a broader use of coronary angioplasty and with an increased use of the early prescription of recognised secondary prevention medications.

Management and short-term outcome of diabetic patients hospitalized for acute myocardial infarction: results of a nationwide French survey.

OBJECTIVES: To compare management and short-term outcome of diabetic and non-diabetic patients hospitalized for acute myocardial infarction. METHODS: This was a prospective epidemiological survey. All patients admitted in coronary care units in France in November 2000 for confirmed acute myocardial infarction were eligible to enter the study. RESULTS: Of the 2320 patients recruited from 369 centers, 487 were diabetic (21%). Compared to non-diabetic patients, diabetic patients were 5 years older, more often female, obese and hypertensive; they had more often a history of cardiovascular disease; they had a lower ejection fraction and worse Killip class. Reperfusion therapy was less frequent among diabetic patients (39% versus 51%; p=0.0001), as was the use of beta-blockers (61% versus 72%; p=0.0001), aspirin (83% versus 89%; p=0.0001) and statins (52% versus 60%; p=0.001) during hospitalization. Conversely, the use of ACE-inhibitors was more frequent (54% versus 44%; p=0.0001). 58% of diabetic patients received insulin during hospitalization. Twenty-eight-day mortality was 13.1% in diabetic patients and 7.0% in non-diabetic patients (risk ratio: 1.87; p=0.001). Diabetes remained associated with increased mortality after adjustment for relevant risk factors including age and ejection fraction (risk ratio: 1.51; p=0.07). In patients treated with antidiabetic drugs (chiefly sulfonylureas) before admission, 28-day mortality was 10.4% compared with 19.9% in diabetic patients on diet alone or untreated (p=0.005). CONCLUSION: Despite higher cardiovascular risk and worse prognosis, in-hospital management of diabetic patients with acute myocardial infarction remains sub-optimal. Patients previously treated with antidiabetic drugs including sulfonylureas had a better prognosis than untreated diabetic patients.

Control of diabetes and cardiovascular risk factors in patients with type 2 diabetes: a nationwide French survey.

OBJECTIVES: To evaluate in France in 2001 the therapeutic management and control of diabetes and of modifiable cardiovascular risk factors in patients with type 2 diabetes receiving specialist care. METHODS: The study was proposed to 575 diabetologists across France. The first 8 consecutive ambulatory patients with type 2 diabetes treated by oral antidiabetic drugs (OADs) and/or insulin attending for consultation with a diabetologist were eligible for inclusion in the survey. The following data were collected: demographics, diabetic and cardiovascular history, cardiovascular risk factors, blood pressure, last recorded measurements of HbA(1c) and LDL cholesterol, and details of diabetes medication and cardiovascular medication. RESULTS: 4, 930 patients (53% men) aged 62 +/- 11 years were recruited by 410 specialists in diabetes care. The mean duration of diabetes was 12 +/- 9 years. 71% of patients were treated with OADs, 18% with an OAD + insulin and 9% with insulin alone. Mean HbA(1c) was 7.6 +/- 1.6%; HbA(1c) was<=6.5% in 27% of patients, between 6.6% and 8% in 39% of patients, and > 8% in 34% of patients. Mean blood pressure was 140 +/- 16/80 +/- 9 mmHg. In the study population as a whole the target blood pressure (systolic BP<140 mmHg and diastolic BP<80 mmHg) was attained by 29% of patients. Among the 3, 085 patients (63%) treated for hypertension, this target was attained in only 23% of patients; 40% of patients treated for hypertension received one single antihypertensive treatment, 36% received 2 treatments and 24% received 3 treatments or more. Among the 1, 845 patients considered by the investigators as not having hypertension, the target blood pressure was attained by 39%. A measurement for LDL cholesterol was available in 4, 036 patients (82%). 58% of these patients had LDL cholesterol<1.3 g/l, 29% had values between 1.3 and 1.6 g/l, and 13% had values > 1.6 g/l. 52% of patients were not receiving any lipid-lowering agents, 28% were treated with statins, 19% with fibrates, and 1% with statins + fibrates. LDL cholesterol was<1.3 g/l in only 66% of the 646 patients with associated coronary heart disease. CONCLUSION: According to this large nationwide survey, the prevalence of cardiovascular risk factors remains high. Control of glycaemia, blood pressure and LDL cholesterol does not appear to be optimal. This is due in part to the severity of diabetes in these patients seen by specialists in diabetes care; however, both awareness and application of published recommendations need to be reinforced.

[Trends in discharge prescriptions for patients hospitalized for acute coronary syndromes in France from 1995 to 2000. Data from the Usik 1995, Prevenir 1, Prevenir 2 and Usic 2000 surveys]. / Evolution du traitement de sortie après hospitalisation pour syndrome coronaire aigu en France entre 1995 et 2000: données des études Usik 1995, Prévenir 1 et 2 et Usic 2000.

The use of cardiovascular secondary prevention medications in patients with acute coronary syndromes was compared in 4 sequential observational surveys carried out in France from 1995 to 2000. The Usik 1995 and Usic 2000 surveys included patients admitted for acute myocardial infarction, while the 2 Prevenir surveys (1998 and 1999) assessed the medications prescribed in patients with acute coronary syndromes. Antiplatelet agents were prescribed in 91% of the patients in 1995, 93% in 1998 and 1999 and 96% in 2000; for beta-blockers, the respective figures were: 64%, 68%, 75% and 76%. For ACE-Inhibitors, the figures were: 46%, 41%, 41% and 50%. For statins, the prescription increased from 10% to 36%, 59% and 64%. In 1995, 8% of the patients received both antiplatelet agents, beta-blockers and statins (4% of them also had an ACE-Inhibitor); in 2000, the respective figures were 53% and 27%. The results of the recent trials of secondary prevention medications have had a considerable impact on real-life practice in France during the late 1990s.

[Efficacy of early reperfusion therapy at the acute stage of myocardial infarction in elderly patients: the USIK database]. / Efficacité du traitement de reperfusion au stade aigu de l'infarctus dans la population âgée: données du registre USIK 1995.

The role of early reperfusion therapy at the acute stage of myocardial infarctus in elderly patients is debated. The aim of this study was to analyze the prognostic role of reperfusion with i.v. thrombolysis or primary PTCA in the nationwide USIK database, which prospectively included all pts admitted to a CCU for an AMI < 48 hours in France in November 1998. For the purpose of the present study, only patients admitted within 24 hours of AMI and with one-year follow-up available were included. Of the 1838 patients included, 785 were > 70 years-old, of whom 225 (29%) had early reperfusion therapy with thrombolysis (N = 173) or primary PTCA (N = 52). Patients treated with early reperfusion had a baseline profile that differed substantially from that of patients treated conventionally: women (31% vs 50%, p < 0.001), admission within six hours of symptom onset (84% vs 55%, p < 0.001), history of systemic hypertension (48% vs 60%, p < 0.002), stroke (5% vs 11%, p < 0.01), peripheral arterial disease (8% vs 18%, p < 0.001); congestive heart failure (5% vs 20%, p < 0.001) or previous MI (12% vs 25%, p < 0.001), more anterior location of current MI (40% vs 28%, p < 0.002). Overall one-year Kaplan-Meier survival was 78% for patients with versus 64% for those without reperfusion therapy (p < 0.01). In patients with Q wave myocardial infarction, Cox multivariate analysis showed that reperfusion therapy was an independent predictor of survival (RR 0.66; 95% Confidence Interval: 0.45-0.96), along with age, anterior location and history of congestive heart failure. Therefore, data from this large "real life" registry indicate that reperfusion therapy with either thrombolysis or primary PTCA is associated with improved one-year survival in patients over 70 years of age.

[Hypertension management in patients with stable coronary disease]. / Prise en charge de l'hypertension chez le patient coronarien en cardiologie libérale.

AIMS: To assess hypertension control in patients with stable coronary disease in France. DESIGN: A cross sectional study was conducted in a representative sample of 794 cardiologists. PARTICIPANTS: The first 6 patients with coronary disease received at practitioner's office were included. MAIN OUTCOME MEASURES: Cardiovascular risk factors, antihypertensive drugs, cardiovascular history were reported. BP was measured. Patients considered as hypertensive by his cardiologist and receiving antihypertensive drugs were considered as hypertensive. Controlled hypertension was defined as a blood pressure < 140/90 mmHg. Uncontrolled hypertension was defined as blood pressure > or = 140/90 mmHg. Among the uncontrolled hypertensives we distinguished patients with isolated systolic hypertension: diastolic blood pressure < 90 mmHg and systolic blood pressure > or = 140 mmHg. RESULTS: All variables were available in 6,349 patients who form the basis of this report. 3,161 patients were hypertensive. Of them, 1,846 (58.4%) were uncontrolled hypertensives, whom 1,280 (69.3%) were uncontrolled on the basis of systolic blood pressure alone. CONCLUSION: This study conducted in a representative sample of French cardiologists indicates that there is a considerable potential to further reduce cardiovascular morbidity in patients in secondary prevention.

[Arterial hypertension management in patients with type 2 diabetes]. / Prise en charge de l'hypertension artérielle chez le diabétique de type 2.

AIMS: To assess hypertension management and blood pressure control in patients with type 2 diabetes in France. DESIGN: A cross sectional study was conducted in a representative sample of 410 diabetologists. The first 8 patients with type 2 diabetes, treated with oral antidiabetic agents and/or insulin, received at practitioner's office were included. Cardiovascular risk factors, antihypertensive drugs, cardiovascular history were reported. BP was measured. Patients considered as hypertensive by his practitioner and receiving antihypertensive drugs were considered as hypertensives. Controlled hypertension was defined as a blood pressure < 140/80 mmHg. Uncontrolled hypertension was defined as blood pressure > or = 140/80 mmHg. RESULTS: 4,930 diabetics were included in the study. Of them 3,085 (63%) patients were hypertensives. They were markedly older, overweight and reported most frequently complications. Only 723 (23%) patients presented with controlled hypertension. 40% of hypertensives were under monotherapy, 36% received 2 antihypertensive treatments and 24% received 3 treatments or more. ACE-inhibitors (49%), diuretics (41%), beta-blockers (35%), calcium channel blockers (33%), angiotensin II antagonists (19%) were the most commonly prescribed agents. Apart from hypertension, the main risk factors associated with each kind of prescription was micro or macroalbuminuria for ACE-I (OR = 1.5), coronary artery disease for beta-blockers and calcium channel blockers (OR = 3.8 and 2.5 respectively), and age for diuretics and angiotensin II antagonists (OR = 1.05 and 1.03). CONCLUSION: This study conducted in a representative sample of french diabetologists indicated that despite the large use of antihypertensive treatments only 23% of hypertensive diabetics were well controlled. Due to the high CV risk of these patients, hypertension management is of major importance.

Is "isolated home" hypertension as opposed to "isolated office" hypertension a sign of greater cardiovascular risk?

BACKGROUND: The SHEAF (Self-Measurement of Blood Pressure at Home in the Elderly: Assessment and Follow-up) study is an observational study (from February 1998 to early 2002) designed to determine whether home blood pressure (BP) measurement has a greater cardiovascular prognostic value than office BP measurement among elderly (> or =60 years) French patients with hypertension. The objective of this present work is to describe the baseline characteristics of the treated patients in the SHEAF study from February 1998 to March 1999, placing special emphasis on "isolated office" and "isolated home" hypertension. METHODS: Baseline office BP measurement was assessed using a mercury sphygmomanometer. Home BP measurement was performed over a 4-day period. A 140/90-mm Hg threshold was chosen to define office hypertension, and a 135/85-mm Hg threshold to define home hypertension. RESULTS: Of the 5211 hypertensive patients in the SHEAF study with a valid home BP measurement, 4939 received treatment with at least 1 antihypertensive drug. Patients with isolated office hypertension represented 12.5% of this population, while patients with isolated home hypertension represented 10.8%. The characteristics of the patients with isolated office hypertension were similar to those of patients with controlled hypertension. However, patients with isolated office hypertension had fewer previous cardiovascular complications. In contrast, rates of cardiovascular risk factors and history of cardiovascular disease in patients with isolated home hypertension resembled those in patients with uncontrolled hypertension. CONCLUSIONS: This retrospective analysis suggests that patients with isolated home hypertension belong to a high-risk subgroup. The 3-year follow-up of these patients will provide prospective data about the cardiovascular prognosis of these subgroups.

Predictors of response to glimepiride in patients with type 2 diabetes mellitus.

OBJECTIVE: The purpose of DIAMETRE (DIabète et Amarel en Monothérapie. Etude de Titration pour la définition des Répondeurs) was to identify factors predictive of response to glimepiride monotherapy in type 2 diabetic patients in the setting of a prospective multicentre open study. MATERIAL AND METHODS: Patients aged 35-70 years with poorly controlled diabetes [fasting plasma glucose (FPG) > or =1,40 g/l and < 3 g/l at baseline] were treated with glimepiride for 6 months, with dosage titrated from 1-6 mg daily, depending on the monthly FPG measurement. Responders were defined as patients with a) FPG < 7.78 mmol/l (1.40 g/l) and HbA(1c) < 7.5% at endpoint, or b) decrease in FPG > or = 20% and/or HbA1c > or = 10%. Stepwise logistic regression analysis was used to identify factors predictive of response. RESULTS: Of 849 patients evaluable for efficacy, 483 (56.9%) were responders. The response was independently influenced by prior treatment with OADs [OR: 0.399 (0.290-0.549), p=0.0001] and diabetes duration [OR: 0.912 (0.877-0.948), p=0.0001]. Ninety patients (9.2%) experienced 124 episodes of symptomatic hypoglycaemia. Multivariate analysis revealed that a high level of HbA(1c) decreased the risk of symptomatic hypoglycaemia [OR: 0.734 (0.628; 0.858), p=0.0001] whereas a family history of type 2 diabetes doubled this risk [OR: 1.956 (1.246; 3.072), p=0.003]. CONCLUSION: This large-scale study, conducted under conditions approximating to current medical practice, confirms that glimepiride has a favourable risk-benefit ratio in type 2 diabetes mellitus. Diabetes duration and previous treatment with OADs reduced the likelihood of being a responder to treatment.

Improved glycaemic control by addition of glimepiride to metformin monotherapy in type 2 diabetic patients.

AIM: To compare the effect of glimepiride in combination with metformin with monotherapy of each drug on glycaemic control in Type 2 diabetic patients. DESIGN AND METHODS: Randomized, double-blind, double-dummy, parallel-group multicentre study conducted in France. Type 2 diabetic patients aged 35-70 years inadequately controlled by metformin monotherapy 2550 mg daily for at least 4 weeks were randomized to either metformin, glimepiride or metformin and glimepiride. RESULTS: Three hundred and seventy-two patients aged 56 +/- 8 years were treated for 5 months. Combination treatment was significantly more efficient in controlling HbA1c (% change + 0.07 +/- 1.20 for metformin, + 0.27 +/- 1.10 for glimepiride, -0.74 +/- 0.96 for combination treatment, P < 0.001), fasting blood glucose (FBG) (mmol/l change + 0.8 +/- 0.4 for metformin, + 0.7 +/- 3.1 for glimepiride and -1.8 +/- 2.2 for combination treatment, P < 0.001) and post-prandial blood glucose (PPBG) (mmol/l change + 1.1 +/- 5.9 for metformin, + 0.1 +/- 5.1 for glimepiride and -2.6 +/- 3.9 for combination treatment, P < 0.001) than either glimepiride or metformin alone. There was no significant difference between metformin or glimepiride monotherapy with respect to the change in HbA1c or FBG; however, glimepiride was significantly more effective than metformin in reducing PPBG. The incidence of symptomatic hypoglycaemia was higher in the combination group than in either monotherapy group (P = 0.039). CONCLUSIONS: Addition of glimepiride to metformin in Type 2 diabetic patients inadequately controlled by metformin alone resulted in superior glycaemic control compared with glimepiride or metformin monotherapy.

[Arterial hypertension management in general practice in France according to global risk factors]. / Contrôle de l'hypertension artérielle en médecine générale en France selon le risque global.

OBJECTIVE: The absolute benefit of antihypertensive medications increases with the level of cardiovascular risk. Moreover in high risk groups, it has been demonstrated that tight blood pressure (BP) control conferred a substantial reduction in the risk of cardiovascular events compared to less tight BP control. Taking into accounts these data, the WHO guidelines recommend to achieve normal BP in high risk subjects. The aim of the study was to assess BP control in a large population of hypertensives (HT) after stratification by cardiovascular risk. METHODS: 15,514 HT defined as office BP > or = 140/90 or the presence of antihypertensive treatment were recruited in France by 3,152 general practitioners. Cardiovascular risk factors and office BP were recorded. Controlled hypertension was defined as a BP < 140/90 mmHg. In patients free of cardiovascular disease, 10-year cardiovascular risks were calculated on the basis of the equations derived from the Framingham Study. RESULTS: 10-year risks were available in 13,560 HT. Those in the highest quartile had greater body mass index (BMI) and the highest concentration of diabetics and current smokers (upper quartile versus lower quartile: BMI: 28.15 vs 26.51 kg/m2; diabetics: 45% vs 3%; current smoking 32% vs 12%; p < .001). [table: see text] Increasing quartiles of risk were associated with the prevalence of uncontrolled hypertension and at a lesser extent with the use of combination therapy. Subjects in the upper quartile had more frequent calcium-blockers, ACE inhibitors and diuretics use and a less frequent betablocker use. CONCLUSION: In general practice, 85% of hypertensives at highest risk are uncontrolled whereas half of them are under monotherapy. An antihypertensive strategy based on global risk may improve BP control in high risk patients.
