Cardiovascular disease risk factors, CHD morbidity and mortality in the Federal Republic of Germany.

Analyses of data from the first National Health Examination Survey undertaken from 1984-1986 within the framework of the German Cardiovascular Prevention Study, show the following risk factor prevalences in 25-69 year-old men and women: overweight (BMI males: greater than 25, females greater than 24) or obese (BMI greater than 30): men 65.0%, women 57.6%; total serum cholesterol (less than 5.17 mmol/dl): men 73.7%, women 74.0%; normal blood pressure (according to JNC definitions): men 45.0%, women 59.1%; hypertension according to WHO criteria: men 26.0%, women 21.1%; controlled hypertensives (WHO criteria): men 19.9%, women 33.9%; current smoking: men 40.8%, women 26.1%. For most of the cardiovascular risk factors there is a clear negative association between prevalence and length of school education. Three myocardial infarction (MI) registries (WHO MONICA Project) are operating in the Federal Republic of Germany. Incidence and case-fatality data are within comparable ranges. Coronary heart disease (CHD) mortality has been relatively stable in both sexes from 1970 to 1986 with a minor peak in 1976 and a slight downward trend since then. A study of the reliability of coding procedures in West German state statistical offices revealed major disagreements so that trends derived from national mortality data as aggregate data of the federal states might be spurious. An ecological correlation of regional smoking prevalences (1978) and regional CHD mortality rates (1977-9) showed significant coefficients in men, but not in women.

Social class and risk factors for coronary heart disease in the Federal Republic of Germany. Results of the baseline survey of the German Cardiovascular Prevention Study (GCP).

The relationship between social class and seven important risk factors for coronary heart disease has been evaluated utilising data from the German Cardiovascular Prevention Study baseline survey. Of German residents aged 25 to 69 years, 16,430 were randomly selected from both the six intervention regions and the Federal Republic of Germany to undergo the screening procedures between 1984 and 1986. Among males the prevalence of cigarette smoking and lack of physical activity was associated with social class. For females, overweight and physical activity demonstrated a strong social gradient. No relationship existed between social class and hypercholesterolaemia. The prevalence of Type A behaviour was significantly higher for the upper social classes. The number of CHD risk factors per study subject increased with decreasing social class. Predicted cardiovascular mortality was clearly higher for the lower social class among males in general and for females younger than 60 years. These findings point to the need for risk factor intervention strategies focusing more on the lower social classes in order to achieve more adequate prevention of coronary heart disease.

Cardiac risk in patients with treatment naïve, first-line medically controlled and first-line surgically cured acromegaly in comparison to matched data from the general population.

INTRODUCTION: Coronary risk factors in patients with acromegaly after first-line transsphenoidal surgery (TSS) or first-line somatostatine analogue (SSA) treatment have rarely been examined. Aim of this study was an evaluation of cardiovascular risk factors and left ventricular hypertrophy (LVH) in 3 different patient groups with treatment naïve, active (ACT), first-line medically controlled (MED) and first-line surgically treated (SUR) acromegaly and a calculation of the Framingham Weibull Risk Score (FS). DESIGN: Retrospective comparative matched case-control study. PATIENTS & METHODS: 40 acromegalic patients (cases aged 45-74 years, 23 men) were matched with respect to age and gender to 200 controls from the general population. 13 patients had treatment-naïve acromegaly (ACT), 12 patients were SSA treated (MED) and 15 patients were operated by TSS (SUR). Coronary risk factors were assessed after 12 months of treatment by interviews and direct laboratory measurements. Only patients normalized for IGF-I in MED and SUR group were included. FS and odds ratios (OR) from multiple conditional logistic regression (matched for age and gender, adjusted for BMI) were calculated. RESULTS: Compared to matched controls ACT patients had higher HbA1c levels (6.9±1.4 vs. 5.5±0.7% (p<0.0001)) and an increased prevalence of left ventricular hypertrophy (LVH) (30.8 vs. 3.2% (p=0.007). MED and SUR groups were similar for gender, age, disease duration and IGF-I levels at diagnosis. Compared to matched controls, MED patients had a significantly increased diastolic blood pressure (89±9 vs. 79±11 mmHg (p=0.001), prevalence of LVH (41.7 vs. 1.7% (p<0.0001), prevalence of diabetes mellitus (33.3 vs. 10.0% (p=0.03)), higher HbA1c levels (6.8±1.3 vs. 5.5±0.7% (p=0.0005)) and a higher FS (21.2±9.7 vs. 12.4±7.7% (p=0.002), OR 1.11 [1.02-1.21] (p=0.01)) while in the SUR group only higher prevalences of LVH (40.0 vs. 4.1% (p<0.0001)) and HbA1c levels (6.4±1.2 vs. 5.5±0.8% (p=0.006)) were found compared to controls. CONCLUSION: When comparing treatment naive, medically treated and surgically cured patients with acromegaly to age- and gender-matched subjects from the general population, we have found an increased cardiovascular risk in patients at 12 months after first-line SSA treatment but not in patients after first-line surgery.
