Although diabetic nephropathy is a slowly progressing, well studied disease, it is the most common cause of end stage renal disease in industrialized countries. Recently the first randomized controlled long term trials about microvascular complications in patients with type 2 diabetes have been published. Only seven years ago the first hallmark papers about metabolic control and ACE inhibition emerged. This review highlights the current status of prevention and therapy of diabetic nephropathy by metabolic and blood pressure control in type 1 and type 2 diabetic patients, depending on their stage of nephropathy (normo-, micro-, or macroalbuminuria). In patients with type 1 diabetes and normo- or microalbuminuria, strict metabolic control has been shown to slow the progression of nephropathy. In macroalbuminuric patients an aggressive antihypertensive treatment, preferably with an ACE inhibitor, is more important than the metabolic control. ACE inhibitor therapy has also been proven beneficial in microalbuminuric patients, but not yet in normotensive, non-albuminuric type 1 patients. Because of the high prevalence of hypertension in patients with type 2 diabetes, a strict antihypertensive treatment is more important than metabolic control for the prevention of progression of microvascular disease. Since most patients need a combination of antihypertensive medications a recommendation for a single substance class can not be given. 相似文献

Diabetes mellitus (DM) is related to increased risks of cardiovascular diseases, such as myocardial infarction, diabetic cardiomyopathy and secondary hypertension. Dissipative energy loss (EL) derived from vector flow mapping (VFM) is thought to reflect the efficiency of blood flow and has been deemed to be an index for the evaluation of left ventricular function. Our study aimed to investigate the value of dissipative EL in diabetic patients with controlled and uncontrolled blood glucose by VFM. Eighty-eight patients with DM and 58 age-matched healthy controls were recruited. All of the patients received echocardiography examinations. VFM analyses were executed to calculate the EL values according to the apical four-chamber examinations from the left ventricle (LV) view. Our results showed that diastolic EL was compromised in the controlled-blood glucose (59.19 mV/m vs. 32.68 mV/m, p?=?0.039) patients and was more dramatically increased in the uncontrolled blood glucose group (88.84 mV/m vs. 32.68 mV/m, p?<?0.001) compared with the healthy controls. The impairment of systolic EL was observed only in the uncontrolled blood glucose patients (39.65 mV/m vs. 20.29 mV/m, p?<?0.001) and not in the controlled blood glucose patients (29.25 mV/m vs. 20.29 mV/m, p?=?0.072). Multivariate backward stepwise linear regression analysis revealed that the HbA1c level was independently related to the diastolic EL (β?=?0.233, p?=?0.026) and systolic EL (β?=?0.237, p?=?0.023). VFM is feasible and reproducible for assessing LV dissipative EL in DM patients with normal LVEF values in whom diastolic EL may be a more vulnerable indicator of early LV cardiac dysfunction in patients with DM. However, LV systolic EL may be a sensitive indicator of preclinical LV dysfunction for patients with DM with uncontrolled blood glucose levels. Uncontrolled blood glucose, which is independently correlated with subclinical LV dysfunction, may lead to increases in systolic EL and diastolic EL in LV. 相似文献

AIM: To study association between the state of the left ventricle (LV) of the heart, characteristics of a 24-h profile of arterial pressure (AP) and episodes of painless myocardial ischemia (PMI). MATERIAL AND METHODS: Echocardiography, bifurcation 24-h monitoring of AP and ECG were conducted in 137 patients with effort angina (EA) receiving clinically effective antianginal therapy. RESULTS: Episodes of PMI at daytime were detected in 33 (24.1%) patients, at day and nighttime in 10 (7.3%) patients. There were significant differences neither by LV state nor by 24-h AP profile in patients free of PMI and those with daytime episodes. Patients with day and night PMI episodes had dilated LV and a decreased fall of night AP. Comparison of the parameters of 24-h AP and ECG monitoring has demonstrated that PMI episodes follow a rise in systolic and diastolic AP. In ischemia systolic and diastolic AP rise. In postischemic period systolic AP lowered while diastolic AP rose higher. CONCLUSION: Changes in diastolic AP may contribute to both onset and arrest of PMI. Decreased night fall in AP is one of the mechanisms compensating impaired coronary circulation. 相似文献

This study was performed to evaluate whether it is possible to distinguish between diabetics with essential hypertension and diabetics with elevated blood pressure due to diabetic nephropathy. We investigated 46 young diabetics, 21 having incipient nephropathy defined as urinary albumin excretion (UAE) persistently above 15 micrograms/min and total urinary protein less than 0.5 g per 24 h, and 25 patients having overt nephropathy with total protein excretion equal to or above 0.5 g per 24 h. Twenty-three patients with essential hypertension were also studied as well as 24 healthy controls. Only males and females between the age of 25 years and 40 years were included. We found a positive correlation between UAE and blood pressure (BP) but a considerable overlap in BP and UAE values between diabetics and patients with essential hypertension. However, plotting urinary albumin excretion against BP, diabetics and non-diabetics with essential hypertension could be nearly totally separated. Comparison at a similar blood pressure level, for example, mean arterial blood pressure of 125 mmHg, shows that diabetics have UAE 100 times higher than non-diabetic essential hypertensives. Conversely, UAE of 100 micrograms/min would imply that mean arterial blood pressure is about 70 mmHg higher in the non-diabetic essential hypertensives than in the diabetics. Five diabetics with normal UAE and elevated blood pressure higher or equal to 160/95 mmHg were clearly within the area of the essential hypertensive patients. Our observations indicate that it seems possible to distinguish diabetic patients with essential hypertension from diabetics with elevated blood pressure due to early or advanced nephropathy. 相似文献

We measured plasma- and extracellular fluid volume (125I-albumin, 51Cr-EDTA), plasma concentrations of renin, angiotensin I and II, aldosterone and atrial natriuretic peptide by radio-immunoassays in insulin-dependent diabetic (IDDM) patients with (n=28) and without (n=11) nephropathy and in 14 normal control subjects matched for sex and age. Glomerular filtration rate (GFR) (ml/min/1.73 m2, single intravenous bolus 51Cr-EDTA technique) was within normal range in all nephropathic patients; 107 (range 78-134). Mean arterial blood pressure (mmHg) was elevated 102 +/- 13 (+/- S.D.) compared to the diabetic and normal control group, 92 +/- 8 and 87 +/- 5, respectively (p less than 0.01). Plasma volume was identical in all three groups while extracellular volume (1/1.73 m2) was expanded in nephropathic patients, 14.5 +/- 1.5 vs 13.1 +/- 0.9 and 12.4 +/- 1.3 in the diabetic and non-diabetic control groups, respectively (p less than 0.05). A significant correlation between extracellular fluid volume and mean arterial blood pressure was found (n=53, r=0.49, p less than 0.001). Active renin was significantly increased in patients with diabetic nephropathy compared with the normal control subjects, while all the remaining hormones were about the same in the three groups. Our study suggests that fluid retention plays a dominant role in the initiation and maintenance of arterial blood pressure elevation early in the course of diabetic nephropathy. 相似文献
