住院2型糖尿病患者短期血压控制及影响因素探讨 总被引:1,自引:0,他引:1
目的:探讨住院2型糖尿病(T2DM)患者短期血压控制效果及影响因素.方法:169例伴发高血压的T2DM患者给予降压等综合治疗,以出院时血压130/80 mmHg(1 mmHg=0.133 kPa)为界限分为达标组(97例)及未达标组(72例),比较2组入院时临床及实验室指标,并通过回归分析观察各种因素对出院时平均动脉压(MAP)水平的影响.结果:全组T2DM入院时收缩压(SBP)为(143±15)mmHg,舒张压(DBP)为(78±8)mmHg,控制达标率仅17.8%;出院时血压达标率57.4%,降压药物种类平均增加0.8种.未达标组患者入院时SBP[(151±15)∶(137±12)mmHg,P<0.01]、DBP[(80±9)∶(77±7)mmHg, P<0.01]均高于达标组,且TC及24 h尿白蛋白排泄率(UAE)显著升高.回归分析显示MAP与入院时SBP、DBP、TC及高血压病程显著正相关,与年龄呈负相关;MAP与UAE显著正相关(r=0.303, P<0.01).并发糖尿病肾病(DN)患者随UAE增多而SBP显著升高,大量蛋白尿者需要多种降压药物联合且血压难以控制.结论:T2DM患者门诊血压控制达标率低,住院短期治疗明显改善了血压控制水平;住院T2DM患者血压控制受入院时血压水平、高血压病程、高胆固醇血症、高UAE等因素影响;UAE增加可能是并发DN患者血压难以控制的直接原因. 相似文献

BACKGROUND: Arterial hypertension greatly increases the risk of cardiovascular disease, renal insufficiency, and retinopathy in patients with type 2 diabetes. Epidemiological studies all document a reduced risk for the aforementioned consequences at a blood pressure (BP) lower than 130/80 mmHg. For this reason, lower target BPs are recommended by recent guidelines committees. A lower threshold BP for treatment, also proposed in guidelines, could facilitate the attainment of the recommended target BP. However, little data exist on the efficacy and safety of starting pharmacological therapy in type 2 diabetic patients exhibiting high-normal BP (HNBP) or the first stage of isolated systolic hypertension previously considered as borderline isolated systolic hypertension (BISH). OBJECTIVE: To determine the antihypertensive efficacy and safety of the fixed-dose combination of the non-dihydropiridine calcium channel blocker (CCB) and ACE inhibitor verapamil SR/trandolapril 180/2 mg (V + T), versus trandolapril 2 mg (T), versus placebo (P) in previously untreated type 2 diabetic patients diagnosed as having HNBP or BISH. METHODS: Multicentric, double-blind, placebo-controlled study with a 16-week follow-up in three groups totalling 438 participants. The primary end-point was to attain the recommended guideline goal of a systolic BP (SBP) value lower than 130 mmHg in all patients and a diastolic BP (DBP) value lower than 85 mmHg in HNBP. Participants were randomized (2:2:1) to verapamil V + T, T, or P. Doses were doubled at week 8 if BP was not controlled. RESULTS: Both active groups were more effective than placebo to decrease SBP and DBP. The mean difference in SBP from placebo was 7.1 mmHg (3.3-10.9, 95% confidence interval (CI); P < 0.001) for T and 7.8 mmHg (3.9-11.6, 95% CI; P < 0.001) for V + T, with no statistical difference between both active groups. Combined treatment (V + T) decreased DBP by 4.6 mmHg (2.3-6.9, 95% CI; P < 0.001) more than placebo and 2.1 mmHg (0.3-4.0, 95% CI; P = 0.021) more than T. At the end of the study, 36.5% in the T group, 37.8% in the V + T group, and 14.9% (P = 0.009, P versus V + T and T) had attained the primary end-point. No significant difference was found between T and V + T with regard to the percentage of good control for SBP, but the control rate on the DBP (DBP < 85 mmHg) was significantly higher in the V + T group (88.8%), when compared with T (79.1%) or P (63.5%) (P = 0.002). Withdrawal rates due to adverse effects did not differ among trandolapril alone (9.4%), the combination (11.7%) and placebo (8.1%). CONCLUSION: Antihypertensive treatment is more effective than placebo for controlling SBP and DBP in previously untreated participants with type 2 diabetes exhibiting low threshold BP values. Combination therapy with verapamil SR/trandolapril was more effective than trandolapril alone for controlling DBP. 相似文献

Effects of Rhythm Control on Blood Pressure . Introduction: The long‐term effects of atrial fibrillation (AF) on blood pressure (BP) in patients with hypertension (HTN) remain unclear. We hypothesized that restoration of normal sinus rhythm (NSR) results in a decrease in BP despite the expected increase in cardiac output. Methods and Results: Twenty‐four‐hour BP measurements were obtained during AF, and on Day 1 and Day 30 post‐successful cardioversion in 18 patients with AF and HTN (cardioversion group), and another 22 patients with AF and HTN with no immediate plans for cardioversion (control group). Except for the duration of AF, the clinical characteristics and use of medications were similar between the groups. In the cardioversion group, a significant decrease in diastolic blood pressure (DBP) and mean blood pressure (MBP) were noted on Day 1 post‐cardioversion with no significant change in systolic blood pressure (SBP): 117/74/88 ± 13/9/9 mmHg during AF and 116/70/85 ± 13/9/10 mmHg during Day 1 post‐cardioversion (P = 0.68; <0.01 and 0.04 for SBP, DBP, and MBP, respectively). In the 13 subjects who remained in NSR at Day 30, DBP and MBP decreased further on Day 30 when compared to Day 1 with no significant change in SBP: 118/76/90 ± 13/7/8 mmHg during AF; 119/72/88 ± 12/8/9 mmHg during Day 1; and 118/69/86 ± 10/8/7 mmHg during Day 30 post‐cardioversion (P = 0.97; <0.001 and 0.03 for SBP, DBP, and MBP, respectively). In the control group, no significant changes in BP were noted. Conclusion: Restoring NSR in patients with AF and HTN resulted in a sustained decrease in DBP and MBP. To our knowledge, this is the first study to show that maintenance of NSR improves BP control in patients with AF and HTN. (J Cardiovasc Electrophysiol, Vol. 23, pp. 722‐726, July 2012) 相似文献

Background Sildenafil, frequently used as on demand medication for the treatment of erectile dysfunction (ED), has been suggested to improve endothelial function but also to alter blood pressure (BP) and induce sympathetic activation. In people with type 2 diabetes mellitus (T2DM), a high‐risk population, the safety profile and the effects on endothelial function of a maximal sildenafil dose (100 mg) have not been investigated and therefore constituted the aim of our study. Methods A double‐blind, placebo‐controlled, cross‐over trial using a single dose of 100 mg sildenafil or placebo has been conducted in 40 subjects with T2DM without known CVD. Haemodynamic parameters, flow mediated dilatation (FMD) in brachial artery, cardiovascular autonomic function tests and spontaneous baroreflex sensitivity (BRS) were measured. Results Sixty minutes after administration of sildenafil but not placebo, a fall of supine systolic blood pressure (SBP) (?5.41 ± 1.87 vs. + 0.54 ± 1.71 mmHg) and diastolic blood pressure (DBP) (?4.46 ± 1.13 vs. + 0.89 ± 0.94 mmHg), as well as orthostatic SBP (?7.41 ± 2.35 vs. + 0.94 ± 2.06 mmHg) and DBP (?5.65 ± 1.45 vs. + 1.76 ± 1.00 mmHg) during standing occurred, accompanied by an increase in heart rate (+1.98 ± 0.69 vs. ? 2.42 ± 0.59 beats/min) (all p < 0.01 vs. placebo). Changes in BP to standing up, FMD, time domain and frequency domain indices of heart rate variability (HRV) and BRS were comparable between sildenafil and placebo. Conclusions Sildenafil administered at a maximum single dose to T2DM men results in a mild increase in heart rate and decrease in BP, but it induces neither an acute improvement of FMD nor any adverse effects on orthostatic BP regulation, HRV and BRS.

Hyperlipidemia, hypertension, and diabetes mellitus (DM) are well-established risk factors for cardiovascular disease. We analyzed the cardiovascular events in hyperlipidemic patients with or without DM who were administered open-labeled simvastatin in groups stratified by blood pressure level using data from the Japan Lipid Intervention Trial (J-LIT). Hyperlipidemic patients with DM (n=6,288) had significantly more cardiovascular events than those without DM (n=33,933). The incidence rates of total cardiovascular events in the Non-DM and DM groups were 15.40 and 25.76 per 1,000 patients for the 6-year period, respectively. The relative risk of total cardiovascular events in the DM vs. the Non-DM group was 1.68, and the relative risk was significantly higher in the DM than in the Non-DM group. The relative risks of total cardiovascular events were significantly higher in DM and Non-DM patients whose systolic blood pressure (SBP) was greater than or equal to 130 mmHg compared to that of Non-DM patients whose SBP was less than 130 mmHg, and in DM and Non-DM patients whose diastolic blood pressure (DBP) was greater than or equal to 80 mmHg compared to that of Non-DM patients whose DBP was less than 80 mmHg. In all groups stratified by SBP and DBP, relative risks of total cardiovascular events were higher in DM patients than in Non-DM patients. For patients with hypercholesterolemia and DM, blood pressure should be strictly controlled in order to prevent both coronary events and stroke. These results are in good agreement with the JNC 7 and the ESH/ESC guidelines for DM patients, which recommended that the SBP and DBP be less than 130 and 80 mmHg, respectively. 相似文献

The Copenhagen City Heart Study (CCHS) is a longitudinal epidemiological study of 19698 subjects followed up since 1976. Variation in blood pressure (BP) measurement in the first three CCHS surveys is evaluated by assessing two components, systematic variation and random variation [daytime and seasonally variation, observer bias, non-response bias, variation with explanatory variables, such as diabetes, hypertension, body mass index (BMI), height, plasma cholesterol and smoking] for the purpose of identifying relevant errors in population surveys. BP was measured in the seated position after a 5 min rest, with the cuff around the non-dominating arm, in accordance with recommended guidelines. The participation rate fell from 74% in survey 1 to 63% in survey 3. Significant non-response bias with respect to BP values was not found. No daytime variability was noted either in systolic (SBP) or diastolic (DBP) BPs. A trend towards a lower BP was seen during the summertime. Random variation, expressed as the standard deviation of the measured values, increased with increasing BP values (SBP: 11.9-13.4 to 21.2- 25.1 mmHg; DBP: 10.6-11.2 to 11.9-13.4 mmHg). SBP was positively correlated to BMI and plasma cholesterol. SBP was 5-10 mmHg higher in diabetics ( p = 0.000-0.04) than in age- and sex-matched nondiabetics. DBP did not differ between the two groups. Smokers from the age of 50 years had a 2-4 mmHg lower SBP ( p = 0.000-0.01) and 1-3 mmHg lower DBP ( p = 0.000-0.005) than had non-smokers. In addition, significantly fewer smokers took antihypertensive medication than did non-smokers ( p = 0.000). In conclusion, judging from the degree of association with BP and/or differences between the three surveys, the most important factors to consider were seasonal variation, BMI, the use of antihypertensive drug therapy, plasma cholesterol, smoking status and diabetes. An inter-survey comparison of BP in population cohorts requires controlling for these factors. 相似文献
