- OBJECTIVE: To evaluate antihypertensive treatment and other cardiovascular risk factors in primary health care.DESIGN: Cross-sectional survey of consecutive patients with treated hypertension in 1999.SETTING: 17 primary care centres in Sweden.SUBJECTS: 512 patients (mean age 67; SD 11 years).MAIN OUTCOME MEASURES: Antihypertensive treatment, cardiovascular risk factors.RESULTS: Patients with high diastolic BP (> or = 100 mmHg) and systolic BP (> 180 mmHg) values were few. The proportions with diastolic BP < 90, BP < 160/95 and < 140/90 mmHg were 64%, 54% and 15%. Mono-therapy was given in 51%, and > or = 3 drugs in 13%. Hypertensives with hyperlipidaemia were 42%, and only 26% of them were given lipid-lowering drugs, mainly statins, 21%. Smokers were 10%, 23% had diabetes, and many had overweight BMI = 25 kg/m2, 72%.CONCLUSION: Although two-thirds had diastolic BP < 90 mmHg, few had BP below the current treatment target < 140/90 mmHg. More than half of the hypertensives had at least one additional cardiovascular risk factor, and these hypertensives also had low proportions within several current treatment targets of hypertension and hyperlipidaemia, implying a need for intensified multiple risk factor intervention.

- Objectives: Estimate risks of coronary heart disease (CHD), stroke and cardiovascular disease (CVD) with updated mean systolic (SBP) and diastolic (DBP) blood pressure in an observational study of patients with type 2 diabetes. Methods: Thirty-five thousand and forty-one patients treated with antihypertensive drugs, and 18 512 untreated patients, aged 30-75 years, without previous heart failure, followed for 6 years until 2009. Results: In treated patients, nonlinear splines for 6-year risk of fatal/nonfatal CHD, stroke and CVD by BP as a continuous variable showed a progressive increase with higher SBP from 140 mmHg and higher, and with DBP from 80 mmHg, with a J-shaped risk curve at lowest SBP levels, but not obviously at lowest DBP levels. Analysing intervals of SBP with 130-134 mmHg as reference at Cox regression, adjusted hazard ratios (HR) for fatal/nonfatal CHD, stroke and CVD with at least 140 mmHg were 1.22 [95% confidence interval (CI): 1.08-1.39], 1,43 (1.18-1.72), 1.26 (1.13-1.41), all P<0.001. HR with 115-129 and 135-139 mmHg were nonsignificant, whereas increased with 100-114 mmHg, 1.96 (P<0.001), 1.75 (P=0.02), 2.08 (P < 0.001), respectively. With DBP 75-79 mmHg as reference, adjusted HR for fatal/nonfatal CHD, stroke and CVD with DBP 80-84 mmHg were 1.42 (1.26-1.59), 1.46 (1.24-1.72), 1.39 (1.26-1.53), all P< 0.001. Corresponding HR with DBP at least 85 mmHg were 1.70 (1.50-1.92), 2.35 (1.99-2.77), 1..87 (1.69-2.07), all P < 0.001. Corresponding HR with DBP 60-69 and 70-74 mmHg were nonsignificant. The picture was similar in 7059 patients with previous CVD and in untreated patients. Conclusion: BP around 130-135/75-79 mmHg showed lower risks of cardiovascular diseases in patients with type 2 diabetes.

- A prospective study of normoalbuminuric diabetic patients was performed between 1997 and 2002 on 4097 type 1 and 6513 type 2 diabetic patients from the Swedish National Diabetes Register (NDR); mean study period, 4.6 years. The strongest independent baseline risk factors for the development of microalbuminuria (20-200 microg/min) were elevated HbA(1c) and diabetes duration in both types 1 and 2 diabetic patients. Other risk factors were high BMI, elevated systolic and diastolic BP in type 2 patients, and antihypertensive therapy in type 1 patients. A subsequent larger cross-sectional study in 2002 showed that established microalbuminuria was independently associated with HbA(1c), diabetes duration, systolic BP, BMI, smoking and triglycerides in types 1 and 2 diabetic patients, and also with HDL-cholesterol in type 2 patients. Relatively few types 1 and 2 patients with microalbuminuria achieved treatment targets of HbA(1c) < 6.5% (21-48%), BP < 130/85 mmHg (33-13%), cholesterol < 5 mmol/l (48-46%), triglycerides < 1.7 mmol/l (83-48%) and BMI < 25 kg/m(2) (50-18%), respectively. In conclusion, high HbA(1c), BP and BMI were independent risk factors for the development of microalbuminuria in types 1 and 2 diabetic patients. These risk factors as well as triglycerides, HDL-cholesterol and smoking were independently associated with established microalbuminuria. Treatment targets were achieved by a relatively few patients with microalbuminuria.

- OBJECTIVE - Risk prediction models obtained in samples from the general population do mot perform well in type 2 diabetic patients. Recently, 5-year risk estimates were proposed as being more accurate than 10-year risk estimates. This study presents a diabetes-specific equation for estimation of the absolute 5-year risk of first incident fatal/nonfatal cardiovascular disease (CVD) in type 2 diabetic patients with the use of A1C and clinical characteristics.RESEARCH DESIGN AND METHODS - The study was based on 11,646 female and male patients, aged 18-70 years, from the Swedish National Diabetes Register with 1,482 first incident CVD events based on 58,342 person-years with mean follow-up) of 5.64 years.RESULTS - This risk equation incorporates A1C, as in the UK Prospective Diabetes Study risk engine, and several clinical characteristics: onset age of diabetes, diabetes duration, sex, BMI, smoking, systolic blood pressure, and antihypertensive and lipid-reducing drugs. All predictors included were associated with the Outcome (P < 0.0001, except for BMI P = 0.0016) with Cox regression analysis. Calibration was excellent when assessed by comparing observed and predicted risk. Discrimination was sufficient, with a receiver operator curve statistic of 0.70. Mean 5-year risk of CVD in all patients was 12.0 +/- 7.5%, whereas 54% of the patients had a 5-year risk >= 10%.CONCLUSIONS - This more simplified risk equation enables 5-year risk prediction of CVD based on easily available nonlaboratory predictors in clinical practice and A1C and was elaborated in a large observational study obtained from the normal patient population aged up to 70 years.
